So I accidentally published my AWS keys to GitHub, stupid me. I realize this the next day.

$ git reset
$ git push
Reset keys in AWS

I was too late. Bot already stole the keys and started up 53 EC2 instances. Racked up $4000+ of compute time (probably Bitcoin mining, I'd assume)

4 weeks later, I finally have this shit disputed and settled.

Don't test with hardcoded keys. You WILL forget about them. Env vars always. That is all.

Linux sucks.

Now now, chill. I'm using it as my main OS for a few years now. I know what I'm talking and this title is a bit click-baity, but this just has to go out there:

1. It's usable as a Windows replacement just fine - FALSE. XFCE4 is years old and buggy as hell especially on multi-monitor set-up, Gnome3 gets stuck more often than my Windows 98 machine used to, KDE is like a rich kid on meth. Plug in Bluetooth headphones? Well no, sorry, you have to research that online, since you'll probably need to install some packages for it to work. Did I say "work"? Well no, because after more research you realize that Debian on Gnome3 on gdm3 launches pulseaudio on its own, so you have 2 instances of pulseaudio, and one of them is stealing your headphones sometimes and you either have no sound or shitty sound. How do I know that you ask? The same way I know everything else - every time you try to do something new on any Linux, it involves a ton of research. Exciting research, don't get me wrong, but at this point it looks more like a toy than a reliable desktop computer operating system.

2. And why am I using pulseaudio? Why not alsa? years ago people were discussing on forums that pulseaudio is old and dead, yet here we are with new LTS release of Ubuntu still shining with Pulseaudio. How about several different service management systems being deprecated by new ones, each having different configurations and calling methods? Apparently systemd is old and lame now. It's a mix of 10 year old software that works badly, with a 5 year old replacement that works worse, somehow trying to live under the same roof. Does it work? Ask my headphones who sound like a fucking dial-up modem.

3. Let's talk about displays, shall we? xorg is old and deprecated, right? We got Wayland that's mostly stable. Don't know what that is? That's just basic knowledge for Linux. And when you try to install network-manager, it also tries to install Mir toolkits. Because why the fuck not install 3 display managers when you want a network manager, of which one is old and dying, one is young and stupid, and another is an infant that died of cancer?

4. Want to integrate with Google Drive? Yeah, there's a tool that mounts the drive as a local directory. Yeah only for Ubuntu. Want it on Debian? You need to compile it. Oh wait, it's on Ocaml, because fuck mainstream languages, we're hipsters. How do you compile Ocaml? Well you need to have Ocaml on your system, dummy. How do you do that? Well you need to compile Ocaml. Ok, how do I do that? Well, git clone, download and install some dependencies, configure, make... oh sorry, you're using libssl1.0.2g when you need libssl1.0.1f, nope, sorry, won't work. Want to install libssl1.0.1f? Why? You already have the "g", stupid! Want to remove libssl1.0.2g? Bye-bye literally everything that you have on your PC. But at least you got the "f". Does it work now? Well no, because you need libssl1.0.2g for another dependency to work.
And all I ever wanted was to get a fucking document from google drive (not nudes, I promise).

5. Want to watch a movie? Let me tear that screen in half and make the bottom half late by a couple of frames, because who needs vertical sync, right? Oh you do? Well install the native drivers maybe. Oh you have? Welcome to eternal Boot to Recovery mode, motherfucka!

---------------------------------

Yeah, most of the times things work just fine. But the reason I know what those things are and how they work is not curiosity. The reason that I know the inner workings of Linux much better than the inner workings of Windows, is because in those few years that I've been using it full time, it has caused me 10 times more headache than I have ever experienced with other systems. And it's not the usual annoyances like "OMG it rebooted when I didn't ask it to", but more like "Oh, it won't work and I need 2 days to find out why" kind of stuff, because even if you experience the same thing again, it's always caused by some new shit and the old solution won't work any more.

I still love it, and will continue to use it. I don't know why really. Maybe because I'm not afraid of fucking it up any more? Maybe because I can do what I want in it and recovering will be easier than on Windows?
It's a toy for me, after all these years. And I also use it for professional reasons.

But whenever someone presents it as a better alternative to Windows, I just want to puke.

Royally fucked up my computer by having my application open 50 instances of itself. I can't even move my mouse...

My team handles infrastructure deployment and automation in the cloud for our company, so we don't exactly develop applications ourselves, but we're responsible for building deployment pipelines, provisioning cloud resources, automating their deployments, etc.

I've ranted about this before, but it fits the weekly rant so I'll do it again.

Someone deployed an autoscaling application into our production AWS account, but they set the maximum instance count to 300. The account limit was less than that. So, of course, their application gets stuck and starts scaling out infinitely. Two hundred new servers spun up in an hour before hitting the limit and then throwing errors all over the place. They send me a ticket and I login to AWS to investigate. Not only have they broken their own application, but they've also made it impossible to deploy anything else into prod. Every other autoscaling group is now unable to scale out at all. We had to submit an emergency limit increase request to AWS, spent thousands of dollars on those stupidly-large instances, and yelled at the dev team responsible. Two weeks later, THEY INCREASED THE MAX COUNT TO 500 AND IT HAPPENED AGAIN!

And the whole thing happened because a database filled up the hard drive, so it would spin up a new server, whose hard drive would be full already and thus spin up a new server, and so on into infinity.

Thats probably the only WTF moment that resulted in me actually saying "WTF?!" out loud to the person responsible, but I've had others. One dev team had their code logging to a location they couldn't access, so we got daily requests for two weeks to download and email log files to them. Another dev team refused to believe their server was crashing due to their bad code even after we showed them the logs that demonstrated their application had a massive memory leak. Another team arbitrarily decided that they were going to deploy their code at 4 AM on a Saturday and they wanted a member of my team to be available in case something went wrong. We aren't 24/7 support. We aren't even weekend support. Or any support, technically. Another team told us we had one day to do three weeks' worth of work to deploy their application because they had set a hard deadline and then didn't tell us about it until the day before. We gave them a flat "No" for that request.

I could probably keep going, but you get the gist of it.

Simple 1 day task. This idiot takes two weeks and after 7 days of hounding finally opens a pull request.

I go in to review the code. Should be a simple 10-15 line patch.

13,000 lines of code changed.

THIRTEEN THOUSAND!

"I fixed a bunch of formatting mistakes and replaced all instances of single quotes to double. Consistency is important you know."

Why do some non-devs treat professional app development like some kids craft-making hobby that requires zero skill and knowledge or brain?
A friend (with ZERO knowledge about coding) said to me today, teach me, or tell me how to learn this app development, I'll learn it within a month and make my own apps plus do freelance app work in free time, apps fetch plenty of money easily. Blah blah.
Not the first time, other non dev friends have talked in the same way on other instances.
It's insulting and infuriating. I don't even know what to reply.

My coworker shared account keys of Amazon aws on a public repo at Github. Took me around 3 days to find out and about 20 ec2 instances were created and running by a hacker...

Playing Warcraft and similar games prepared me for understanding Classes and Instances in Object Orientation later.

I wrote a database migration to add a column to a table and populated that column upon record creation.
But the code is so freaking convoluted that it took me four days of clawing my eyes out to manage this.
BUT IT'S FINALLY DONE.
FREAKING YAY.

Why so long, you ask? Just how convoluted could this possibly be? Follow my lead ~

There's an API to create a gift. (Possibly more; I have no bloody clue.)
I needed the mobile dev contractor to tell me which APIs he uses because there are lots of unused ones, and no reasoning to their naming, nor comments telling me what they do.

This API takes the supplied gift params, cherry-picks a few bits of useful data out (by passing both hashes by reference to several methods), replaces a couple of them with lookups / class instances (more pass-by-reference nonsense). After all of this, it logs the resulting (and very different) mess, and happily declares it the original supplied params. Utterly useless for basically everything, and so very wrong.

It then uses this data to call GiftSale#create, which returns an instance of GiftSale (that's actually a Gift; more on that soon).

GiftSale inherits from Gift, and redefines three of its methods.

GiftSale#create performs a lot of validations / data massaging, some by reference, some not. It uses `super` to call Gift#create which actually maps to the constructor Gift#initialize.

Gift#initialize calls Gift#pre_init (passing the data by reference again), which does nothing and returns null. But remember: GiftSale inherits from Gift, meaning GiftSale#pre_init supersedes Gift#pre_init, so that one is called instead. GiftSale#pre_init returns a Stripe charge object upon success, or a Gift (and a log entry containing '500 Internal') upon failure. But this is irrelevant because the return value is never actually used. Pass by reference, remember? I didn't.

We're now back at Gift#initialize, Rails finally creates a Gift object using the args modified [mostly] in-place by all of the above.

Another step back and we're at GiftSale#create again. This method returns either the shiny new Gift object or an error string (???), and the API logic branches on its type. For further confusion: not all of the method's returns are explicit, and those implicit return values are nested three levels deep. (In Ruby, a method will return the last executed line's return value automatically, allowing e.g. `def add(a,b); a+b; end`)

So, to summarize: GiftSale#create jumps back and forth between Gift five times before finally creating a Gift instance, and each jump further modifies the supplied params in-place.

Also. There are no rescue/catch blocks, meaning any issue with any of the above results in a 500. (A real 500, not a fake 500 like last time. A real 500, with tragic consequences.)

If you're having trouble following the above... yep! That's why it took FOUR FREAKING DAYS! I had no tests, no documentation, no already-built way of testing the API, and no idea what data to send it. especially considering it requires data from Stripe. It also requires an active session token + user data, and I likewise had no login API tests, documentation, logging, no idea how to create a user ... fucking hell, it's a mess.)

Also, and quite confusingly:
There's a class for GiftSale, but there's no table for it.
Gift and GiftSale are completely interchangeable except for their #create methods.

So, why does GiftSale exist?
I have no bloody idea.
All it seems to do is make everything far more complicated than it needs to be.

Anyway. My total commit?
Six lines.
IN FOUR FUCKING DAYS!

When I was in college, I had some serious knob-heads in my class. They kept on asking where they could download free movies.

So I made a .bat file called "free movies". It had a nice icon and everything. And placed it on their desktops.

What did it do?

Kept spawning message boxes that read "do some math bitch" and opening new instances of the calculator.

It was too brilliant to see people watch their computers crash, and might I add, crash slowly, because these computers had tons of ram.

Never click on "free movies" kids.

WWDC was not about developers this year. It was a conference call with shareholders and investors. No bold moves, just several consecutive "this product will no longer suck" and "look at what you can do now, big companies" announcements.

watchOS will work now (it's too slow ATM). tvOS will just be less cumbersome. macOS still lagging behind (I mean, I already have great third party apps that clean my hard drive, but thank you for solving a problem I didn't need fixing). iOS 10 is simply about messages (it's not going to make me ditch Telegram, because it doesn't have an Android client, regardless of how large you make emoticons appear on screen). Apple Music will still suck, especially if you have more than one Apple ID. And Apple Maps will continue to be useless outside of the US.

Where did the bold moves go? Where's the "we're breaking up iTunes into several distinct apps that serve their purposes really well"? (Guess iTunes is too valuable a trademark...) Where is the "we will end the WKView vs UIView vs NSView nonsense"? (You know, OOP is about creating classes, which are abstractions and whose instances deal with the particularities of their environment; a View is a View, regardless of where they live; an instance of a View should care about being on a watch or on a phone, not the developer.) Where is the "we love indie developers and will help you"? They showed off a lot of integration with well established apps, that don't really need to stand out any more. They showed that video of "normal people" who have developed apps, but no one knows about them! And then they changed the AppStore so you can pay to advertise your app, but who has the means to do that? Indie devs are surely on a tight budget, so who's that helping again?

For me, this WWDC was sugar coated with a "we love you developers" BS, but was a business statement to large companies ("see what you can do now Uber, Lyft, WeChat, WhatsApp, Doordash, all the P2P payment apps, ESPN, WSJ and so on?"). It's already a known fact that the bulk of the AppStore revenue goes to the top 1% apps. And what's the point of having tvOS be open to developers if it is very unlikely I'll ever develop anything for it unless I work at CBS?

It's great that they want to make it easier for kids to learn Swift. But there's very little point in that, if those kids' apps aren't going to be used and are simply going to make the "we have 2 million apps on the AppStore" announcement look shinier for shareholders. Without a strong indie community, the Swift Playgrounds app for the iPad is just manufacturing workers for large corporations.

And without a strong indie community, things get tougher for indie clients as well. Who will have the money (and therefore the time) to implement all those integrations in order to even dream about competing with heavily funded apps?

Yeah... So thanks, Apple, but no thanks.

!rant I read some documentation about Amazon, "save all the data in my butt".
- me laughing
* I installed the extension that replaces all the instances of" the cloud " by "my butt". I'm easily entertained ;p

!dev

lol I keep getting in trouble over people taking secondhand-offense, and managers keep bringing up the same instances like I’m somehow at fault.

Look, if Alice says something to Bob, and Carol hears it and gets offended on Bob’s behalf, but Bob doesn’t? Carol should jump off a bridge.

It's enough. I have to quit my job.

December last year I've started working for a company doing finance. Since it was a serious-sounding field, I tought I'd be better off than with my previous employer. Which was kinda the family-agency where you can do pretty much anything you want without any real concequences, nor structures. I liked it, but the professionalism was missing.

Turns out, they do operate more professionally, but the intern mood and commitment is awful. They all pretty much bash on eachother. And the root cause of this and why it will stay like this is simply the Project Lead.

The plan was that I was positioned as glue between Design/UX and Backend to then make the best Frontend for the situation. Since that is somewhat new and has the most potential to get better. Beside, this is what the customer sees everyday.

After just two months, an retrospective and a hell lot of communication with co-workers, I've decided that there is no other way other than to leave.

I had a weekly productivity of 60h+ (work and private, sometimes up to 80h). I had no problems with that, I was happy to work, but since working in this company, my weekly productivity dropped to 25~30h. Not only can I not work for a whole proper work-week, this time still includes private projects. So in hindsight, I efficiently work less than 20h for my actual job.

The Product lead just wants feature on top of feature, our customers don't want to pay concepts, but also won't give us exact specifications on what they want.
Refactoring is forbidden since we get to many issues/bugs on a daily basis so we won't get time.
An re-design is forbidden because that would mean that all Screens have to be re-designed.
The product should be responsive, but none of the components feel finished on Desktop - don't talk about mobile, it doesn't exist.
The Designer next to me has to make 200+ Screens for Desktop and Mobile JUST so we can change the primary colors for an potential new customer, nothing more. Remember that we don't have responsiveness? Guess what, that should be purposely included on the Designs (and it looks awful).
I may hate PHP, but I can still work with it. But not here, this is worse then any ecommerce. I have to fix legacy backend code that has no test coverage. But I haven't touched php for 4 years, letalone wrote sql (I hate it). There should be no reason whatsoever to let me do this kind of work, as FRONTEND ARCHITECT.

After an (short) analysis of the Frontend, I conclude that it is required to be rewritten to 90%. There have been no performance checks for the Client/UI, therefor not only the components behave badly, but the whole system is slow as FUCK! Back in my days I wrote jQuery, but even that shit was faster than the architecuture of this React Multi-instance app. Nothing is shared, most of the AppState correlate to other instances.

The Backend. Oh boy. Not only do we use an shitty outated open-source project with tons of XSS possibillities as base, no we clone that shit and COPY OUR SOURCES ON TOP. But since these people also don't want to write SQL, they tought using Symfony as base on top of the base would be an good idea.
Generally speaking (and done right), this is true. but not then there will be no time and not properly checked. As I said I'm working on Legacy code. And the more I look into it, the more Bugs I find. Nothing too bad, but it's still a bad sign why the webservices are buggy in general. And therefor, the buggyness has to travel into the frontend.

And now the last goodies:
- Composer itself is commited to the repo (the fucking .phar!)
- Deployments never work and every release is done manually
- We commit an "_TRASH" folder
- There is an secret ongoing refactoring in the root of the Project called "_REFACTORING" (right, no branches)
- I cannot test locally, nor have just the Frontend locally connected to the Staging webservices
- I am required to upload my sources I write to an in-house server that get's shared with the other coworkers
- This is the only Linux server here and all of the permissions are fucked up
- We don't have versions, nor builds, we use the current Date as build number, but nothing simple to read, nonono. It's has to be an german Date, with only numbers and has always to end with "00"
- They take security "super serious" but disable the abillity to unlock your device with your fingerprint sensor ON PURPOSE

My brain hurts, maybe I'll post more on this shit fucking cuntfuck company. Sorry to be rude, but this triggers me sooo much!

Rocky Linux.

The ancient Linux distro, presumably the main desktop Linux used by cavemen.

You can still see some instances running these days.

Today a friend of mine kinda broke windows

Description:
There are 4 desktop instances, all of them "work" perfectly fine. Partly overlapping eachother

We have a group slack chat for my class which was intended to be a space for asking questions about assignments and getting help from your peers. Instead it has become a dick measuring contest in there where guys who know very little can act all high and mighty about their (plain wrong, in some instances) facts they're distributing without care. It pisses me off so much seeing how toxic it has become in there. It's the same 5 guys using it to bully each other and God forbid anyone else asks a question, they'll be mocked for not being confident handing in a solution they aren't sure is right. Why can't people treat each other with respect? We're in school to LEARN. Not impress other students with how much (read: little) we know. GJ, guys. You created a smaller version of stack overflow.

The website for our biggest client went down and the server went haywire. Though for this client we don’t provide any infrastructure, so we called their it partner to start figuring this out.
They started blaming us, asking is if we had upgraded the website or changed any PHP settings, which all were a firm no from us. So they told us they had competent people working on the matter.

TL;DR their people isn’t competent and I ended up fixing the issue.

Hours go by, nothing happens, client calls us and we call the it partner, nothing, they don’t understand anything. Told us they can’t find any logs etc.

So we setup a conference call with our CXO, me, another dev and a few people from the it partner.
At this point I’m just asking them if they’ve looked at this and this, no good answer, I fetch a long ethernet cable from my desk, pull it to the CXO’s office and hook up my laptop to start looking into things myself.

IT partner still can’t find anything wrong. I tail the httpd error log and see thousands upon thousands of warning messages about mysql being loaded twice, but that’s not the issue here.
Check top and see there’s 257 instances of httpd, whereas 256 is spawned by httpd, mysql is using 600% cpu and whenever I try to connect to mysql through cli it throws me a too many connections error.

I heard the IT partner talking about a ddos attack, so I asked them to pull it off the public network and only give us access through our vpn. They do that, reboot server, same problems.

Finally we get the it partner to rollback the vm to earlier last night. Everything works great, 30 min later, it crashes again. At this point I’m getting tired and frustrated, this isn’t my job, I thought they had competent people working on this.

I noticed that the db had a few corrupted tables, and ask the it partner to get a dba to look at it. No prevail.

5’o’clock is here, we decide to give the vm rollback another try, but first we go home, get some dinner and resume at 6pm. I had told them I wanted to be in on this call, and said let me try this time.

They spend ages doing the rollback, and then for some reason they have to reconfigure the network and shit. Once it booted, I told their tech to stop mysqld and httpd immediately and prevent it from start at boot.

I can now look at the logs that is leading to this issue. I noticed our debug flag was on and had generated a 30gb log file. Tail it and see it’s what I’d expect, warmings and warnings, And all other logs for mysql and apache is huge, so the drive is full. Just gotta delete it.

I quietly start apache and mysql, see the website is working fine, shut it down and just take a copy of the var/lib/mysql directory and etc directory just go have backups.

Starting to connect a few dots, but I wasn’t exactly sure if it was right. Had the full drive caused mysql to corrupt itself? Only one way to find out. Start apache and mysql back up, and just wait and see. Meanwhile I fixed that mysql being loaded twice. Some genius had put load mysql.so at the top and bottom of php ini.

While waiting on the server to crash again, I’m talking to the it support guy, who told me they haven’t updated anything on the server except security patches now and then, and they didn’t have anyone familiar with this setup. No shit, it’s running php 5.3 -.-

Website up and running 1.5 later, mission accomplished.

Today is sprint demo day. As usual I'm only half paying attention since being a Platform Engineer, my work is always technically being "demoed" (shit's running ain't it? There you go, enjoy the EC2 instances.)

One team presents a new thing they built. I'm still half paying attention, half playing Rocket League on another monitor.

Then someone says

"We're storing in prod-db-3"

They have my curiosity.

"Storing x amount of data at y rate"

They now have my attention. I speak up "Do you have a plan to drop data after a certain period of time?"

They don't. I reply "Okay, then your new feature only has about 2 months to live before you exhaust the disk on prod-db-3 and we need to add more storage"

I am asked if we can add more storage preemptively.

"Sure, I say." I then direct my attention to the VP "{VP} I'll make the change request to approve the spend for additional volume on prod-db-3"

VP immediately balks and asks why this wasn't considered before. I calmly reply "I'm not sure. This is the first time I'm learning of this new feature even coming to life. Had anyone consulted with the Platform team we'd have made sure the storage availability was there."

VP asks product guy what happened.

"We didn't think we'd need platform resources for this so we never reached out for anything".

I calmly mute myself, turn my camera back off and go back to Rocket League as the VP goes off about planning and collaboration.

"CT we'll reach out to you next week about getting this all done"

*unmute, camera stays off* "Sounds good" *clears ball*

Now seriously, WHAT THE FUCK???
Every single time I have to work with people from a particular country [you have one guess. Yepp, that's the one], I see A-FUCKING-LOOOOOOT of manual work?!?

"can you reboot the server?"
-"sure, let me help you, sir" <20 minutes later> "done"

"can you unlock my account?"
-"yes, just a moment sir" <20 minutes later> "please check now"

"can you restart this environment w/ 200 instances?"
-"yes sir, let me check" <6 hours later> "please check now"
"you've missed 18 containers"
-"oh okay sir, will restart them now" <2hours later> "please check now"
[I am already OoO]

why is it that every time I have to work with you guys I am the one who is automating shit. How come you never think of/do any automata? You are fucking technitians, you should know how. WHY DO YOU ENJOY CLICKING ALL-DAY-LONG????

I'm serious. Why??? I'm struggling to understand...

TL;DR
I accidentally surpassed(?) my user permissions and closed some of my classmates browsers and locked up a terminal for me

In school we have 2 primary operating systems: Windows and Ubuntu. Windows is hell in general and but not as hell as the firefox installation on Ubuntu.

"Just loaded this page. Now wait half a minute so that I can render it"
"Woah, woah, woah. Slow there. You just made an input event. Give me those 5 seconds to compute what you just did"

Executing "top" or "htop" shows you a long list of firefox processes with a cpu usage of 99.9%, since the whole school shares that linux environment.

Anyway, one day it was way more servere than normally and I way forced to kill my firefox instances. So I pressed CTRL+ALT+T for that terminal, waited 5 minutes until it accepted input typed "killall firefox" with a delay of half a minute per character and smahed that enter key.

At this very point in time I could hear confusion from every corner of the room. "What happened to firefox?"

Around 30% of the opened browsers where abruptly stopped. I looked back to my screen noticed I was logged out. I couldn't login from that terminal for the rest of that day.

Our network admin, which happened to be there, since the server is just next door, said that this was just convenience, but the timing was too perfect so I heighly doubt that.

I felt like a real hackerman even if it was by accident :)

...i just remembered why I have a MasturbatorPattern repository on my bitbucket, why is it named that way, and what it does.

It's one of the core abilities of that magical AI i've mentioned in my previous rant. And it's called that way, because of how it works:

The Agent has some objects (as in, class instances) available to it, and wants to get some other kind of object. So it inspects by reflection ("touches") all objects around itself, inspecting their public functions, building up a plan/path/tree of "this function takes the object I have as input, and returns this other object which this other function of other object takes as input and returns this different object, which...." etc, etc, until the final function returns the object the Agent wanted to get in the first place.

And then it goes and "does" all those functions, in that order piping the parameters through.

So first it touches them (second layer of metaphor - linux finger command), and then it does those which output (ejaculate =D) something useful to it.

Therefore, MasturbatorPattern =D

Not sure if my sense of humor is just weird or outright unfunny.

Pour one out for our last VMS/Alpha computers heading to the great bit bucket in the sky.

Was decent hardware in it's day, 20 years ago, but we now run EC2 instances that are faster. 🙃

Ugh I'm getting so owned. Currently having a burst DDOS on a host of ours. It is always at xx:00 and xx:30 for ~2 minutes from ~200++ unique AWS instances (Ip's).

Not long enough to ban them (max 2-3 requests per IP), not general enough to ban them on the type of request.. and the IP's.. yea... It would result banning all the amazon subnets which is also not an option lol.

Now waiting I guess.. I sent an email to amazon

When I was about 10 I tried to make a basic midi sequencer/synthesiser using just the python standard library.
The only sound production there was was winsound.beep, which played a sine wave at the frequency given.
I realised that if I put enough really short beeps together I could make some mildly convincing instruments - I remember an electric piano, acoustic guitar, some kind of bass synth, and maybe more?
Then I put them together to make a song. The problem was though that you can't play multiple notes together as winsound.beep was blocking (though I didn't understand that at the time).
I had no knowledge of threading or async so I opened multiple python interpreter instances to play multiple channels. That's how I learnt about command-line arguments!
But I really struggled to get the sounds to be in time because python is not exactly rapid.
I made a kind of note sequencer using a library called easygui, based on tkinter (TCL wrapper), and I remember being told off at school for bringing in a usb stick with the exe of my program that I made with py2exe.
So many old technologies and fond memories...

# PROD

* 10 app instances running
* 1 instance starts burning up 100% cpu
* we ask for a Thread Dump (stack traces)
* we get a TD taken after they manually restarted the instance
* they: "Please investigate. We need this fixed ASAP"
* .....

EVERY FUCKING TIME!!! Not once in recent years have they managed to take a TD correctly. What kind of a retarded monkey do you have to be for this to not sink in for YEARS!

Who tf put those idiot monkeys there in the first place...

colleague: AWS is facing some network issue.

me: But I see you are able to SSH into EC2 instances.

colleague: Well, I am running my nodejs app on 8080 but can't access it over the Internet. Works fine on my laptop though.

me: ec2_prod ~# netstat | grep node
lolol -> 127.0.0.1:8080 node

Turns out it was running on localhost IP. Worked fine on his laptop though.

Me: develops my first android app with firebase by google.
Me: finishes app, tests it and it works.

Firebase after 3 months: we were first going to scale our servers on our own based on how many people are simultaneously using your app. But now fuck you, we will have a cap of 100000 simultaneous users.

Me: fuck this kills my app if it scales. Have to Shard everything on the db side and overhaul the entire app to work will multiple db instances. Takes a month.

Android after 6 months: dude your app is working fine without any hiccups. Let me fuck it up. We will stop all your services when your app is not running or backgrounded. Also we will make it illegal to start services in this case and we will throw exceptions.

Me: what the actual fuck. They now want me to focus on a JobScheduler, fine... But now even intent services won't work properly. So use a job scheduler to start a JobIntentService which is essentially another job scheduler for queuing. wtf android.

Ps solved it and works again.

PS: WAITING FOR ANDROID TO FML WITH ANOTHER NEW VERSION. Maybe they'll say you can't run your app at all now

Threaded API Calls, or rather:

How I killed five server instances in one shot..

Creating 50000 Threads sounds like a good idea in general, the bad part starts when you use start() in a for loop to run them all at once.

No further comments your honor...

Spent an hour and a half renaming a method everywhere in a project from `feature_name` to `feature_name!`. There are a lot of constants, symbols, and other methods that use "feature_name" as a prefix (plus comments and spec descriptions), so was a little more difficult than normal.

Should have taken like 5 minutes with a proper IDE refactor tool. but noo, it was too difficult for RubyMine. wah wah wah. Stupid thing. Not even the search tool was useful -- it's limited to 100 results, and there were around 250 for that substring.

I ended up having to run specs repeatedly to find all the remaining instances, which took freaking forever. blahhh

We are developing a single page APPLICATION which will be embeded into another single page APPLICATION using iframes (!?!?!?!). The embedded SINGLE PAGE application has POPUPS (browser instances, not UI popups) opened. Every app contains at least 75% of the other apps and they do not share common code. Everything in IE11 and ng4.

My most satisfying bug fix?

I found a core concurrency issue in this gnarly homegrown ORM and reported it to the lead devs, who (very defensively, having written the damn thing) argued that it would never pop up in a prod environment and I was stupid for even bringing it up. Theoretically, this bug could cause pretty much every foreign key to be assigned to the wrong parent, but only if multiple instances of the application were open/running at once. They were so certain it would never happen on live that they explicitly instructed me not to fix it. After all, this bug had been active for many years on a previous project and nobody complained.

Problem was, that previous project was something that only a single user had open most of the time (think: a manager). The new project was something that would be used by multiple people at the same time (think: all the employees). Once we released this new-project-with-old-orm, it didn't take long at all for our customers to start complaining.

After that, they let me fix the bug. :)

Old rant here. Took place ~2 years ago and just remembered it recently:

For some reason our company decided to disable incognito mode in Chrome... Wtf, who comes up with that shit?!
Our team has different certificates to test our application and therefore the private mode comes in quite useful. Otherwise you would need to close and reopen all browser instances again.

At least, after a shitstorm from various teams they unblocked incognito again.

I'm having an existential crisis with this client.

We are spending millions of $s every year to make sure the product's performance is perfect. We are testing various scenarios, fine-tuning PLABs: the environment, application, middleware, infra,... And then we provide our recommendations to the client: "To handle load of XX parallel users focusing on YY, yy and Zy APIs, use <THIS> configuration".

And what the client does?
- take our recommendations and measure the wind speed outside
- if speed is <20m/s and milk hasn't gone bad yet, add 2x more instances of API X
- otherwise add 3xX, 1xY and give more CPUs to Z
- split the setup in half and deploy in 2 completely separate load-balanced prod environments.
- <do other "tweaking">

- bomb our team with questions "why do we have slow RTs?", "why did the env crash?", "why do we have all those errors?", "why has this been overlooked in PLABs?!?"

If you're improvising despite our recommendations, wtf are we doing here???

One day I will crack. Hopefully, not sometime soon.

Current task:

Somehow, one of my predecessors made some sort of custom hook tied to woocommerce check out that pipes some data into a nightmarish spaghetti fuck pile of undocumented wild west visual basic bullshit. It does this, presumably, via a set of parameters passed as plaintext in a url. I know this because I found the singleton that declares this. Helpfully, Mr. Fuckass named the class "Default", so I only have around 30k instances being kicked back by my IDE when I search for it. The only reason I "need" to find this, is so that I can just change the button to an href pointing at my own MS for shipping, and I need to change the fifteen params being passed to just one - a customer ID, which should be stored in the session, and referenced by a cookie. Once that is done, I should be able to freely delete a couple of gigs worth of bullshit. Been stuck on this for three days now. God forbid we have a test environment or something.

I'm tired. Can't even get angry anymore really. Can't even think of anything funny to say about it either, I just can't wait until this is done and I can go back to sleep.

I find it funny on Windows, Android studio reaches as much as 12GB of ram usage, while on Linux two instances barely take up to 3GB

Either java sucks on Windows or AS sucks in memory usage but happened to be saved by Linux

Just read a comment on rant that stated "You’d be surprised as how disgusting people are especially in the work setting.". In regard to bathrooms. This reads true, for my current place of work

I was about to reply to that, but I thought this is worthy of a rant of its own. Allow me to quote some emails...

"We have had reports of excrement being left on toilet seats, which surely could be seen by the person responsible before they left the cubicle. "

"very poor toilet hygiene in some the ladies toilets.

Firstly, someone person should I say.... has used a toilet brush to clear a blockage in the Ladies loo nearest [removed]. They obviously couldn't unblock the toilet due to the density of the blockage and therefore.. returned the brush to it's holder full of the blockage!! "

"The phantom "snot" wiper is back and is using the back of the toilet door nearest the [removed] as a tissue! Again.. the poor Cleaner has had to clean this up... "

"Toilet paper being put in the Urinal blocking the system in [removed] and faeces being left on the toilet floor in [removed]. This goes without saying that this can't go on and it's not the cleaners job to be cleaning such messes! "

Its ever worse in our other office that contains a call centre. A lady was fired for leaving shit in the stairwells on multiple instances. She had been fired from her last role for the same thing.

There were also reports of subway subs been left in the toilet bowl.

You also find the most curious items in the waste bins (they have no lid, we're not search through them - just to make that clear) everything from half eaten sandwiches to watermelon.

I'm 2 months into my first dev job. Today, I was working on upgrading one of our products to React 18. Had a feeling my UI changes weren't being pushed to AWS so I wanted to test that. Changed all labels from ".. filter users..." to "shmilter shusers". Committed, then nearly pushed those changes for a PR. There are multiple lines of defence and only a 5% chance that no one would spot it but as soon as I realized that there's a small possibility that our customers would suddenly see "shmilter shusers" on their instances, I had an absolute fit. Maybe it's a "you had to be there" kind of thing but I don't remember the last time I laughed this hard.

Well, I suppose there's no rules against talking about a non-tech company situation.

Before I made it into my career as a developer, I wrote code as a self-learned hobby programmer. I had a job though, which was selling chips. No, not ICs... potato chips. Funny enough, I made a killing doing it.

Anyway, this isn't about me. It's about the guy who quit shortly after I showed up. You see, we all had company trucks and most of us parked them at the warehouse and commuted in our own vehicles. We'd load the trucks up with product and lock them up in the yard for the next day.

It used to be that there was an option to take the truck home, but after this gentleman, that was reserved for special instances.

That would be due to the fact that the guy played "hide the chip truck" and called up to quit his job, forcing my former boss to hunt around an entire city to find the damn thing.

I've found it isn't so different in software, except when people quit, it's more like "hide the actual deployed branch you didn't commit".

Want to make someone's life a misery? Here's how.

Don't base your tech stack on any prior knowledge or what's relevant to the problem.

Instead design it around all the latest trends and badges you want to put on your resume because they're frequent key words on job postings.

Once your data goes in, you'll never get it out again. At best you'll be teased with little crumbs of data but never the whole.

I know, here's a genius idea, instead of putting data into a normal data base then using a cache, lets put it all into the cache and by the way it's a volatile cache.

Here's an idea. For something as simple as a single log lets make it use a queue that goes into a queue that goes into another queue that goes into another queue all of which are black boxes. No rhyme of reason, queues are all the rage.

Have you tried: Lets use a new fangled tangle, trust me it's safe, INSERT BIG NAME HERE uses it.

Finally it all gets flushed down into this subterranean cunt of a sewerage system and good luck getting it all out again. It's like hell except it's all shitty instead of all fiery.

All I want is to export one table, a simple log table with a few GB to CSV or heck whatever generic format it supports, that's it.

So I run the export table to file command and off it goes only less than a minute later for timeout commands to start piling up until it aborts. WTF. So then I set the most obvious timeout setting in the client, no change, then another timeout setting on the client, no change, then i try to put it in the client configuration file, no change, then I set the timeout on the export query, no change, then finally I bump the timeouts in the server config, no change, then I find someone has downloaded it from both tucows and apt, but they're using the tucows version so its real config is in /dev/database.xml (don't even ask). I increase that from seconds to a minute, it's still timing out after a minute.

In the end I have to make my own and this involves working out how to parse non-standard binary formatted data structures. It's the umpteenth time I have had to do this.

These aren't some no name solutions and it really terrifies me. All this is doing is taking some access logs, store them in one place then index by timestamp. These things are all meant to be blazing fast but grep is often faster. How the hell is such a trivial thing turned into a series of one nightmare after another? Things that should take a few minutes take days of screwing around. I don't have access logs any more because I can't access them anymore.

The terror of this isn't that it's so awful, it's that all the little kiddies doing all this jazz for the first time and using all these shit wipe buzzword driven approaches have no fucking clue it's not meant to be this difficult. I'm replacing entire tens of thousands to million line enterprise systems with a few hundred lines of code that's faster, more reliable and better in virtually every measurable way time and time again.

This is constant. It's not one offender, it's not one project, it's not one company, it's not one developer, it's the industry standard. It's all over open source software and all over dev shops. Everything is exponentially becoming more bloated and difficult than it needs to be. I'm seeing people pull up a hundred cloud instances for things that'll be happy at home with a few minutes to a week's optimisation efforts. Queries that are N*N and only take a few minutes to turn to LOG(N) but instead people renting out a fucking off huge ass SQL cluster instead that not only costs gobs of money but takes a ton of time maintaining and configuring which isn't going to be done right either.

I think most people are bullshitting when they say they have impostor syndrome but when the trend in technology is to make every fucking little trivial thing a thousand times more complex than it has to be I can see how they'd feel that way. There's so bloody much you need to do that you don't need to do these days that you either can't get anything done right or the smallest thing takes an age.

I have no idea why some people put up with some of these appliances. If you bought a dish washer that made washing dishes even harder than it was before you'd return it to the store.

Every time I see the terms enterprise, fast, big data, scalable, cloud or anything of the like I bang my head on the table. One of these days I'm going to lose my fucking tits.

A few days ago Aruba Cloud terminated my VPS's without notice (shortly after my previous rant about email spam). The reason behind it is rather mundane - while slightly tipsy I wanted to send some traffic back to those Chinese smtp-shop assholes.

Around half an hour later I found that e1.nixmagic.com had lost its network link. I logged into the admin panel at Aruba and connected to the recovery console. In the kernel log there was a mention of the main network link being unresponsive. Apparently Aruba Cloud's automated systems had cut it off.

Shortly afterwards I got an email about the suspension, requested that I get back to them within 72 hours.. despite the email being from a noreply address. Big brain right there.

Now one server wasn't yet a reason to consider this a major outage. I did have 3 edge nodes, all of which had equal duties and importance in the network. However an hour later I found that Aruba had also shut down the other 2 instances, despite those doing nothing wrong. Another hour later I found my account limited, unable to login to the admin panel. Oh and did I mention that for anything in that admin panel, you have to login to the customer area first? And that the account ID used to login there is more secure than the password? Yeah their password security is that good. Normally my passwords would be 64 random characters.. not there.

So with all my servers now gone, I immediately considered it an emergency. Aruba's employees had already left the office, and wouldn't get back to me until the next day (on-call be damned I guess?). So I had to immediately pull an all-nighter and deploy new servers elsewhere and move my DNS records to those ASAP. For that I chose Hetzner.

Now at Hetzner I was actually very pleasantly surprised at just how clean the interface was, how it puts the project front and center in everything, and just tells you "this is what this is and what it does", nothing else. Despite being a sysadmin myself, I find the hosting part of it insignificant. The project - the application that is to be hosted - that's what's important. Administration of a datacenter on the other hand is background stuff. Aruba's interface is very cluttered, on Hetzner it's super clean. Night and day difference.

Oh and the specs are better for the same price, the password security is actually decent, and the servers are already up despite me not having paid for anything yet. That's incredible if you ask me.. they actually trust a new customer to pay the bills afterwards. How about you Aruba Cloud? Oh yeah.. too much to ask for right. Even the network isn't something you can trust a long-time customer of yours with.

So everything has been set up again now, and there are some things I would like to stress about hosting providers.

You don't own the hardware. While you do have root access, you don't have hardware access at all. Remember that therefore you can't store anything on it that you can't afford to lose, have stolen, or otherwise compromised. This is something I kept in mind when I made my servers. The edge nodes do nothing but reverse proxying the services from my LXC containers at home. Therefore the edge nodes could go down, while the worker nodes still kept running. All that was necessary was a new set of reverse proxies. On the other hand, if e.g. my Gitea server were to be hosted directly on those VPS's, losing that would've been devastating. All my configs, projects, mirrors and shit are hosted there.

Also remember that your hosting provider can terminate you at any time, for any reason. Server redundancy is not enough. If you can afford multiple redundant servers, get them at different hosting providers. I've looked at Aruba Cloud's Terms of Use and this is indeed something they were legally allowed to do. Any reason, any time, no notice. They covered all their bases. Make sure you do too, and hope that you'll never need it.

Oh, right - this is a rant - Aruba Cloud you are a bunch of assholes. Kindly take a 1Gbps DDoS attack up your ass in exchange for that termination without notice, will you?

I have a couple of thoughts about social justice controversies from these last years.

I think it's hard to have a good opinion about these events for several reasons.

One reason is that finding good information in 2019 is very hard.

Revenue based sites (thus unneutral) dominate the search results. You search about something and you find thousands of sites basically saying the same thing (because they copy each other).

That's why the existence of a free and open search engine is so important, so it's easier to find neutral hence good information on which to base your opinions, but they are prohibitively big for small groups to build.

Another reason is that controversies generate shock and shock curtails rational thinking. Maybe that's how the primitive brain works?

I'm not much of a scholar to feel confident to say that, but it's so recurrent that it's not too much of a wild guess.

When a controversy happens, a natural reaction is to pick a side. This means that:
a) we assume that there are only 2 sides, and
b) we must pick one of them

So, maybe the human is a bad politician by nature?

Also, because of the shock controversies generate, peaceful dialogue is very rare.

I have yet to see peaceful dialogue online about what patriarchy means to feminists and a lot of other terms they use.

I don't care much about feminists that vandalize or interrupt talks (yelling over someone else is abuse in my opinion).

But for the rest of them, I think discussing their ideas would be good.

I say this because most feminist discourse I see online is not open. Or maybe there are such instances but the web is so big that it's hard to find such instances.

I think some part of the modern feminist doctrine is bullshit, and some part is true.

I for one hate when some men I know in life expect their wives to be their cooks+cleaners (unless they want to do that, willingly). Personally, I'd encourage my wife to get a job (rightfully so, not just to meet some minority quota in some company).

I don't mind either calling a trans person the pronoun she wants.

But other ideas are awful, like the idea that meritocracy is patriarchy, so you need to force minorities to meet a proportionate quota. That's terrible reasoning.

Or the excessive self appreciation culture, like saying to yourself "you are pretty, you are beautiful, you are perfect". I think that grows arrogance and black-or-white thinking.

And some other ideas as well.

I guess the same you can say about any doctrine with different degrees. Some part is bullshit, some part isn't.

Some right wing people hate everyone who isn't white by default, but some want to have more immigration control.

I sure don't like the experiment of separating children from families like the current us govt did, but I wouldn't be happy either to know that by '99 50% of gangs members in the us were hispanic.

With this, I'm not going to say "embrace everyone's ideas" like an idiot. I hate when people do that. It's a stupid and weak reaction to radicalism.

In fact I think the way you fight radicalism and bad doctrines is that you listen to them and maintain good dialogue and counterargue in a respectful but insightful manner.

Making snide remarks, insulting or trolling won't change anyone's mind. That is just throwing fire to the fire.

In fact, when someone gets harassed because of something they believe in, usually it results in even more adherence to their beliefs, because of the usual assumption that success or goodness is full of strife.

So by telling a "sjw" or kkk member that they are idiots over twitter, you are in fact making them stronger believers in their doctrine.

Think of Daryl Davis, a black guy that made 200 members leave the kkk. How? He didn't tell them they were assholes, he somehow made friends with them.

I feel bad now because I've been trolling new devrant users a lot because of how they worsen the quality of the site, but maybe I should tell them that they are ruining the site somehow in a nice way and maybe they'll listen? I dunno...

The worst was an open source project I tried to look at.

It was written in Turbo Pascal.

I am not sure, never really got so far, but it looked like it was one single class with hundreds of methods and hundreds of instance fields for data.

Almost no data objects, if it needed for example 4 sets of 6 variables it had 24 instance fields and in some instances 4 different sets of methods for accessing said variables.

Around there I stopped looking ;)

So building a game engine/framework/thing/thang and was working on a scripting language designed for the Dev terminals commands/applications...

Then I also have to design a language for the asset scripts, instances (probably going to do JSON) and it only took me about 4 months of planning to realise I could just use the same language for everything and just double down on the one.

Well aren't I a fucking dickhead .-.

Monthly Update call
Me : I need 2 undivided weeks in the next 3 months to make some refactoring to our codebase, so we dont have issues in scaling.

Senior Manager (with years of tech experience almost equal to my age) :
Why would we need that, We are already hosted on AWS so we can just spin up more instances.

Me ( trying to hold the rage inside) : No it doesnt work that way, that will only hurt us more than help.

Him : What if we try with a bigger instance size. Its AWS, sure they will have a bigger instance.

Me : No, tha....
Him : (cuts me off) How about we use autoscaling and let AWS decide

Me : (Silently praying for a gun that shots across video calls.)

“Overhearing powers of the Fullstack dev”

We have an internal control panel (BEEP) to manage our dev Tomcat instances. The other day, with one of my muggle friend, I was trying to restart an instance. There’s a checkbox to clean the host tmp files and directories, ingeniously named as - Purge cache.

Innocent Me (to my muggle friend): bro would Purge cache delete the application log files?

__(Fullstack dev overhearing us)__

Muggle friend: Purge ca... (gets interrupted my the Fullstack dev)

Fullstack dev: so the thing is ... it’s like ... (gotta be consistent with the opening) what “npm purge” does is it deletes the files which are not being used.

Confused Muggle friend: bro it’s a BEEP option to clean the tmp dirs.

Fullstack dev: oh I thought you guys were talking about “npm purge”

Angry muggle friend: then WHY THE FUCK did you answer if you didn’t know [...] the fuck we were talking about.

Calm fullstack dev: FYI. Might help you someday.

Deeply-hurt Me: (what the fuck is “npm purge”). Hey man do you mean “npm prune”? Because they don’t have an npm purge. And what do you mean by “it deletes the files which are not being used”?

Confident Fullstack dev: NO

Me: (cries in npm)

More to come!

Everyone and their dog is making a game, so why can't I?
1. open world (check)

2. taking inspiration from metro and fallout (check)

3. on a map roughly the size of the u.s. (check)

So I thought what I'd do is pretend to be one of those deaf mutes. While also pretending to be a programmer. Sometimes you make believe
so hard that it comes true apparently.

For the main map I thought I'd automate laying down the base map before hand tweaking it. It's been a bit of a slog. Roughly 1 pixel per mile. (okay, 1973 by 1067). The u.s. is 3.1 million miles, this would work out to 2.1 million miles instead. Eh.

Wrote the script to filter out all the ocean pixels, based on the elevation map, and output the difference. Still had to edit around the shoreline but it sped things up a lot. Just attached the elevation map, because the actual one is an ugly cluster of death magenta to represent the ocean.

Consequence of filtering is, the shoreline is messy and not entirely representative of the u.s.

The preprocessing step also added a lot of in-land 'lakes' that don't exist in some areas, like death valley. Already expected that.

But the plus side is I now have map layers for both elevation and ecology biomes. Aligning them close enough so that the heightmap wasn't displaced, and didn't cut off the shoreline in the ecology layer (at export), was a royal pain, and as super finicky. But thankfully thats done.

Next step is to go through the ecology map, copy each key color, and write down the biome id, courtesy of the 2017 ecoregions project.

From there, I write down the primary landscape features (water, plants, trees, terrain roughness, etc), anything easy to convey.
Main thing I'm interested in is tree types, because those, as tiles, convey a lot more information about the hex terrain than anything else.

Once the biomes are marked, and the tree types are written, the next step is to assign a tile to each tree type, and each density level of mountains (flat, hills, mountains, snowcapped peaks, etc).
The reference ids, colors, and numbers on the map will simplify the process.

After that, I'll write an exporter with python, and dump to csv or another format.

Next steps are laying out the instances in the level editor, that'll act as the tiles in question.
Theres a few naive approaches:

Spawn all the relevant instances at startup, and load the corresponding tiles.

Or setup chunks of instances, enough to cover the camera, and a buffer surrounding the camera. As the camera moves, reconfigure the instances to match the streamed in tile data.

Instances here make sense, because if theres any simulation going on (and I'd like there to be), they can detect in event code, when they are in the invisible buffer around the camera but not yet visible, and be activated by the camera, or deactive themselves after leaving the camera and buffer's area.

The alternative is to let a global controller stream the data in, as a series of tile IDs, corresponding to the various tile sprites, and code global interaction like tile picking into a single event, which seems unwieldy and not at all manageable. I can see it turning into a giant switch case already.

So instances it is.

Actually, if I do 16^2 pixel chunks, it only works out to 124x68 chunks in all. A few thousand, mostly inactive chunks is pretty trivial, and simplifies spawning and serializing/deserializing.

All of this doesn't account for
* putting lakes back in that aren't present

* lots of islands and parts of shores that would typically have bays and parts that jut out, need reworked.

* great lakes need refinement and corrections

* elevation key map too blocky. Need a higher resolution one while reducing color count
This can be solved by introducing some noise into the elevations, varying say, within one standard div.

* mountains will still require refinement to individual state geography. Thats for later on

* shoreline is too smooth, and needs to be less straight-line and less blocky. less corners.

* rivers need added, not just large ones but smaller ones too

* available tree assets need to be matched, as best and fully as possible, to types of trees represented in biome data, so that even if I don't have an exact match, I can still place *something* thats native or looks close enough to what you would expect in a given biome.
Ponderosa pines vs white pines for example.

This also doesn't account for 1. major and minor roads, 2. artificial and natural attractions, 3. other major features people in any given state are familiar with. 4. named places, 5. infrastructure, 6. cities and buildings and towns.

Also I'm pretty sure I cut off part of florida.
Woops, sorry everglades.

Guess I'll just make it a death-zone from nuclear fallout.

Take that gators!

Ok, this is my first post here...and I came here to rant - I had heard about this place, but I guess I just hadn't had a bad enough day...until today...the day I found my ec2 instance was playing hide and seek with me. I just found out that my aws billing dashboard is going to swoosh 2000rs (30$) out of my wallet. Imagine ranting about this to a layperson... ok anyway, I had taken a t2-medium (my first one ever) for a hackathon and I was just playing with the regions I guess and it somehow ended up in the ohio region. I had given IAM access to some of my teammates and they were using it. We were supposed to shutdown the instance after 1 day. The next day I check the dashboard (for N.Virginia - which is the default) and I see no running instances. I thought ok my teammates must've turned it off and I left it at that. A month after the hackathon, I login today and I have this jaw-dropping moment. I now have to pay 30$ for nothing!

I think that two criterias are important:

- don't block my productivity
- author should have his userbase in mind

1) Some simple anti examples:

- Windows popping up a big fat blue screen screaming for updates. Like... Go suck some donkey balls you stupid shit that's totally irritating you arsehole.
- Graphical tools having no UI concept. E.g. Adobes PDF reader - which was minimalized in it's UI and it became just unbearable pain. When the concept is to castrate the user in it's abilities and call the concept intuitive, it's not a concept it's shit. Other examples are e.g. GEdit - which was severely massacred in Gnome 3 if I remember correctly (never touched Gnome ever again. I was really put off because their concept just alienated me)
- Having an UI concept but no consistency. Eg. looking at a lot of large web apps, especially Atlassian software.
Too many times I had e.g. a simple HTML form. In menu 1 you could use enter. In menu 2 Enter does not work. in another menu Enter works, but it doesn't submit the form it instead submits the whole page... Which can end in clusterfuck.
Yaaayyyy.
- Keyboard usage not possible at all.
It becomes a sad majority.... Pressing tab, not switching between form fields. Looking for keyboard shortcuts, not finding any. Yes, it's a graphical interface. But the charm of 16 bit interfaces (YES. I'm praising DOS interfaces) was that once you memorized the necessary keyboard strokes... You were faster than lightning. Ever seen e.g. a good pharmacist, receptionist or warehouse clerk... most of the software is completely based on short keyboard strokes, eg. for a receptionist at a doctor for the ICD code / pharmaceutical search et cetera.
- don't poop rainbows. I mean it.
I love colors. When they make sense. but when I use some software, e.g. netdata, I think an epilepsy warning would be fair. Too. Many. Neon. Colors. -.-

2) It should be obvious... But it's become a burden.

E.g. when asked for a release as there were some fixes... Don't point to the install from master script. Maybe you like it rolling release style - but don't enforce it please. It's hard to use SHA256 hash as a version number and shortening the hash might be a bad idea.

Don't start experiments. If it works - don't throw everything over board without good reasons. E.g. my previous example of GEdit: Turning a valuable text editor into a minimalistic unusable piece of crap and calling it a genius idea for the sake of simplicity... Nope. You murdered a successful product.
Gnome 3 felt like a complete experiment and judging from the last years of changes in the news it was an rather unsuccessful one... As they gave up quite a few of their ideas.

When doing design stuff or other big changes make it a community event or at least put a poll up on the github page. Even If it's an small user base, listen to them instead of just randomly fucking them over.

One of my favorite projects is a texteditor called Kate from KDE.

It has a ton of features, could even be seen as a small IDE. The reason I love it because one of the original authors still cares for his creation and ... It never failed me. I use Kate since over 20 years now I think... Oo

Another example is the git cli. It's simple and yet powerful. git add -i is e.g. a thing I really really really love. (memorize the keyboard shortcuts and you'll chunk up large commits faster than flash.

Curl. Yes. The (http) download tool. It's author still cares. It's another tool I use since 20 years. And it has given me a deep insight of how HTTP worked, new protocols and again. It never failed me. It is such a fucking versatile thing. TLS debugging / performance measurements / what the frigging fuck is going on here. Take curl. Find it out.

My worst enemies....

Git based clients. I just hate them. Mostly because they fill the niche of explaining things (good) but completely nuke the learning of git (very bad). You can do any git action without understanding what you do and even worse... They encourage bad workflows.
I've seen great devs completely fucking up git and crying because they had really no fucking clue what git actually does. The UI lead them on the worst and darkest path imaginable. :(

Atlassian products. On the one hand... They're not total shit. But the mass of bugs and the complete lack of interest of Atlassian towards their customers and the cloud movement.... Ouch. Just ouch.

I had to deal with a lot of completely borked up instances and could trace it back to a bug tracking entry / atlassian, 2 - 3 years old with the comment: vote for this, we'll work on a Bugfix. Go fuck yourself you pisswads.

Microsoft Office / Windows. Oh boy.
I could fill entire days of monologues.
It's bad, hmkay?

XEN.
This is not bad.
This is more like kill it before it lays eggs.
The deeper I got into XEN, the more I wanted to lay in a bathtub full of acid to scrub of the feelings of shame... How could anyone call this good?!?????

We actually had a small "code on paper" test (more like a recap test) yesterday, but we didn't have to write much rather than just have a basic understanding how classes and instances of those work. It was like 6 small lines of code to insert. I don't mind coding on paper as long as you don't have to write a big program with it as a 1-hour test.

On the nth day of Christmas, my true love gave to me:

1 misconfigured autoscaling group
200 unnecessary servers
29 urgent emails
3 support teams that would have fixed the problem in an hour of anybody had bothered going to them first

Ugh. Idiots. Somehow the whole issue was caused by a single full hard disk, which caused database transactions to fail, which caused the group to scale out and spin up new instances, which didn't actually fix the problem so it kept scaling until it hit the limit and then continuously failed to create new instances for several hours straight, generating loads of notification emails and generally causing problems for everyone involved.

!dev !rant

One of my closest friends at work is 50. He is very well kept despise his age and feels like a young soul to me. The man could be my dad because of his age but we still hang out like regular friends.

I am 27, turn 28 this month.

The other day he said that he was glad I went through the military. He said that it was because of that that I matured way past my age and that thanks to all the traumatic shit I have an older soul.

While I don't disagree, I kinda feel sad at it, it was one of the only instances in which i have felt that my military service has brought something semi good from it.

Friends are cool tho.

So recently I completed side gig from random freelancing site where I had to shadow troubleshoot performance problems over teams call with random Indian guy on his client's AWS account. Long story short you can autoscale new instances all you want but it's not gonna help if your FIFO sqs has only one message group ID. This architecture is running an online game, which is basically limited to processing ONE event at the same time for ALL players xD
What's even better, basing on naming convention I realized it's a company that I interviewed for like 4 months ago and they told me "we need someone with more experience". Well good luck, thanks for quick cash

Ok, here goes...

I was once asked to evaluate upgrade options for an online shop platform.

The thing was built on Zend 1, but that's not the problem.

The geniuses that worked on it before didn't have any clue about best practices, framework convention, modular thinking, testing, security issues...nothing!

There were some instances when querying was done using a rudimentary excuse for a model layer. Other times, they would just use raw queries and just ignore the previous method. Sometimes the database calls were made in strange function calls inside randomly loaded PHP files from different folders from all over the place. Sometimes they used JOINs to get the data from multiple tables, sometimes they would do a bunch of single table queries and just loop every data set to format it using multiple for loops.

And, best of all, there were some parts of the app that would just ignore any ideea of frameworks, conventions and all that and would be just a huge PHP file full of spagetti code just spalshed around, sometimes with no apparent logic to it. Queries, processing, HTML...everything crammed in one file...

The most amazing thing was that this code base somehow managed to function in production for more than 5 years and people actualy used it...

Imagine the reaction I got from the client the moment I said we should burn it to the ground and rebuild the whole thing from scratch...

Good thing my boss trusted me and backed me up (he is a great guy by the way) and we never had to go along with that Frankenstein monster...

Have some troubles with MySQL server with multiple instances.
After some search, I have a “bind-address” parameter set to “127.0.0.1”
Changed to “localhost” do the trick. Love my work.

My mind was blown when I found out AWS offers FPGA instances (EC2 instances)

how fucking cool is that?

My best prank: A year ago I was at my friends flat, which he finally rented with his new girlfriend. He is a kind of person, which has like constantly opened 110 tabs in chrome, three or four instances of chrome running, torrenting at full speed and in the meanwhile a few films having opened to "watch" later. He is very very secure about his computer and NEVER leaves me or anyone else alone with his computer. That day we were just talking in the same room, and he goes for some food. I was like yeah thats my chance to prank him. So I opened a new tab and came with an idea - what If I change his desktop background to some random chick, to prank both him and his gf. I knew she will not be mad but his reaction would be priceless (it was his first gf). So I started googling, found a three pretty naked chicks. This was like soft porn, they were still "dressed" but not much. I did not wanted to use a porn for this.
So I was about to download image - right click - save as - little window opened and..

...what the hell, that guy had literally like terabytes of porn in download folder, all totally in one chaos, thousands of images, millions of downloaded videos, all categories just everything from gangbang to milfs or old/ young, what the fuck that computer was like cursed station of porn.

In that point I was like fuck that. This prank has no sense then. So I just closed that little window and did nothing. Prank failed.

Nowdays, He still does not know what I know about his "hobbies". And I will never say him lol. About a months after he broke with his gf and moved to different house. He has now three monitors attached to his computer and 4tb of space. He is still complaining about "lack of space" and "too big downloaded movies" but we all know what is going on lol. We call his "working deck" a sacred porn station.

Too many to count, but this one useless meeting stands out the most.

I was working as an outside dev for software corporation. I was hired as an UI dev although my skill set was UI/engineer/devops at the time.

we wrote a big chunk of 'documentation' (read word files explaining features) before the project even started, I had 2 sprints of just meetings. Everybody does nothing, while I set up the project, tuned configs, added testing libraries, linters, environments, instances, CI/CD etc.

When we started actual project we had at least 2 meetings that were 2-3 hours long on a daily basis, then I said : look guys, you are paying me just to sit here and listen to you, I would rather be working as we are behind the schedule and long meetings don't help us at all.

ok, but there is that one more meeting i have to be on.

So some senior architect(just a senior backend engineer as I found out later) who is really some kind of manager and didn't wrote code for like 10 years starts to roast devs from the team about documentation and architectural decisions. I was like second one that he attacked.

I explained why I think his opinion doesn't matter to me as he is explaining server side related issues and I'm on the client-side and if he wants to argue we can argue on actual client-side decisions I made.

He tried to discuss thinking that he is far superior to some noob UI developer (Which I wasn't, but he didn't know that).

I started asking some questions and soon he felt lost and offended. We ended that discussion with conclusion that I made my own decisions on the client-side. That lasted less than 10 minutes.

So I just sit there and eat popcorn for next 4 and half hours listening to their unnecessary discussions where some angry manager that did programing decades ago wanted to show that we are all noobs and stupid.

what a sad human being.
what a waste of time, but hey I got payed for this 5 hour meeting.

Ec2 mac instances🤔

We'd just finished a refactor of the gRPC strategy. Upgraded all the containers and services to .Net core 3, pushed a number of perf changes to the base layer and a custom adaptive thread scheduler with a heuristic analyzer to adjust between various strategies.

Went from 1.7M requests/s on 4 cores and 8gb ram to almost 8M requests/s on the same, ended up having to split everything out distributed 2 core instances because we were bottlenecking against 10gb/e bandwidth in AWS.

Cat-warming solution when the power goes out

Problem: Your power goes out in the middle of winter. Your cat is cold and will not leave you alone. You are her only source of heat.

Step 1: Find battery-powered laptop.
Step 2: Power on laptop and turn off sleep/hibernation in the settings.
Step 3: Open up 5 instances of Minecraft and load a single-player world in each.
Step 4: Close laptop and flip it upside down
Step 5: Place cat on computer above the fan. Cat will begin to purr.

(Yes this works)

Recently I've started thinking about how we are always told "No you can't do that" to everything. That feels like a theme in our industry.

I've also been thinking about how often people say well done to each other, or just comment that something is good in a pull request. Everything is always focused on bugs and mistakes - not good bits.

The first point conflicts with the idea that when using languages and frameworks you should follow their philosophy or you're gonna have a bad time - but in all other instances you mostly don't have wrong answers, just answers that can be better so a lot of stuff is opinion based.

I've decided to change my ways and focus just as much on good stuff as bad when I review code and to make sure I'm focusing just as much, if not more, when people do something good.

I think I do a good job, but I don't think I've been told I'm doing a good job or that anything specific is good more than a couple times in the last year - mostly in mandatory reviews. What about you?

Is your code green?

I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.

I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?

* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.

Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.

I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.

In terms of cycles that can be the difference between needing a single core and a thousand cores.

This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.

Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.

I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.

I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.

I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.

The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.

A couple of years ago, we decide to migrate our customer's data from one data center to another, this is the story of how it goes well.

The product was a Facebook canvas and mobile game with 200M users, that represent approximately 500Gibi of data to move stored in MySQL and Redis. The source was stored in Dallas, and the target was New York.

Because downtime is responsible for preventing users to spend their money on our "free" game, we decide to avoid it as much as possible.

In our MySQL main table (manually sharded 100 tables) , we had a modification TIMESTAMP column. We decide to use it to check if a user needs to be copied on the new database. The rest of the data consist of a savegame stored as gzipped JSON in a LONGBLOB column.

A program in Go has been developed to continuously track if a user's data needs to be copied again everytime progress has been made on its savegame. The process goes like this: First the JSON was unzipped to detect bot users with no progress that we simply drop, then data was exported in a custom binary file with fast compressed data to reduce the size of the file. Next, the exported file was copied using rsync to the new servers, and a second Go program do the import on the new MySQL instances.

The 1st loop takes 1 week to copy; the 2nd takes 1 day; a couple of hours for the 3rd, and so on. At the end, copying the latest versions of all the savegame takes roughly a couple of minutes.

On the Redis side, some data were cache that we knew can be dropped without impacting the user's experience. Others were big bunch of data and we simply SCAN each Redis instances and produces the same kind of custom binary files. The process was fast enough to launch it once during migration. It takes 15 minutes because we were able to parallelise across the 22 instances.

It takes 6 months of meticulous preparation. The D day, the process goes smoothly, but we shutdowns our service for one long hour because of a typo on a domain name.

Of course the shouting episodes all happened during the era I was doing WordPress dev.

So we were a team of consultants working on this elephant-traffic website. There were a couple of systems for managing content on a more modular level, the "best" being one dubbed MF, a spaghettified monstrosity that the 2 people who joined before me had developed.

We were about to launch that shit into production, so I was watching their AWS account, being the only dev who had operational experience (and not afraid to wipe out that macos piece of shit and dev on a real os).

Anyhow, we enable the thing, and the average number of queries per page load instantly jumps from ~30 (even vanilla WP is horrible) to 1000+. Instances are overloaded and the ASG group goes up from 4 to 22. That just moves the problem elsewhere as now the database server is overwhelmed.

Me: we have to enable database caching for this thing *NOW*

Shitty authors of the monstrosity (SAM): no, our code cannot be responsible for that, it's the platform that can't handle the transition.

Me: we literally flipped a single switch here and look at the jump in all these graphs.

SAM: nono, it's fine, just add more instances

Me: ARE YOU FUCKIN SERIOUS?
Me: - goes and enables database caching without any approvals to do so, explaining to mgmt. that failure to do so would impair business revenue due to huge loading times, so they have to live with some data staleness -

SAM: Noooo, we'll show you it's not our code.
SAM: - pushes a new release of the monstrosity that makes DB queries go above 2k / page load -

...

Tho on the bright side, from that point on I focused exclusively on performance, was building a nice fragment caching framework which made the site fly regardless of what shitty code was powering it, tuned the stack to no end and learned a ton of stuff in the process which allowed me to graduate from the tar pit of WP development.

FUUCCKKKK!! I need to hit smth. Or rant..

So that flaky ec2 issue.. These ec2s act as a shared environment for multiple apps. Our app is one of them. I have no access to those ec2s at all.

What I have access to is my app and some monitoring. Now the app randomly starts lagging while nearly idling. At the same random times monitoring stops completely and doesn't come back up. This happens to random app instances at random times.

Reached out to infra support, managed to get attention from the big boys [mgmt]. Today we got the fix deployed. I test it out -- problem persists.

I find this behaviour somewhat familiar. Managed to get some server stats from infra folks. Apparently cpu% is high as well as load avg [cpu queue]. Bingo! I know how to fix it!

So I write a long comment w/ all the commands and all the 'if that, do this'. Send it to one of the infra technitians

and I get a reply: 'we will apply cpu usage limitations to fix the issue'

wait... Cpu% limitations will do nothing but highlight the underlying problem...

'no, instances have high cpu utilisation which is causing those lags. We will limit cpu resources and it will be fixed'

oh ffs... Cpu utilization and cpu queue are VERY different things.. I tried explaining that to them like 7-9 times. And all I get is:

'yes, cpu utilization is the problem. We will limit it and solve the problem'

I would surely escalate all of this through higher channels if only I could get my hands on those ec2s and have a proof. But that is not happening and I'm forced to sit back and watch them break things even worse until they are out of options and mark my query as 'wont fix'....

Fuck that's frustrating....

*thinking to myself* so I've read about that new vulnerability 2 days ago that allows one to escape from docker container to the host... What if <...>

So I was assigned to improve an existing internal CMS application where they wanted the ability to add extra form applications and restricting them based on people from different departments. As well as include some other improvements like speed as they mentioned that it was slow in some instances.

What I found was the original developer decided to not use any kind of framework and decided to be creative by creating his own MVC framework. With about 300 users in this system and utilising no caching of queries, views, not even using PHP OpCache, even quite a few security holes, I was damn surprised at how this thing was running. I asked the original developer why he didn't use an open source framework and he said that he thought that he'd create something and be the next Facebook.

It was a mammoth task to "improve" this system but the main thing was that I took custody of this project and that I prevented him from trying to make a bigger mess of things for this project.

I was writing some migrations and I had to do THIS. Could I have named my variables differently? Didn't wanna... 😈

Request I saw today...

* A new, empty AWS Account
* The ability to run 120 high memory EC2 instances, including up to 80 instances of dl1.24xlarge, but don't worry, 40 of them will be spot instances. I'll probably just start with two m5.xlarge for simplicity.
* VPC Peering into our primary AWS network
* VPC Peering into a 3rd party's network (because we're paying them for this service)
* A couple cross-acount IAM roles
* Granting "AWS: AdministratorAccess" to said IAM roles

I'm a bit behind schedule, and this is urgent. When will you have this completed?

my job went from being a programmer ==> technical support girl for the whole company D:

its kinda annoying because its mostly about amazon ec2 instances and i have to chat with the support team from amazon when something goes wrong while following the steps (that the others could have followed instead of going to directly to me to make me do it)
now i have to try and fix all the problems occuring in the servers :((

I was experimenting with a load test suite called 'Siege' to build and scale increasingly complex searches against our new site search engine. I assumed that an old iMac couldn't have generated a crushing load against the beta servers and I learned two things the day I wrote and started that script before heading to lunch:

1) Beta and Production shared MSSQL instances
2) That single iMac was more than enough to take the whole production site down...

I'm writing a devrant like site, so a kind of forum that supports live chat under every article. Login will be just username and password to stay anonymous. Email is optional for password reset. Also it won't have password requirements. Who cares if user uses insecure password. I do like the devrant avatar thing. I will use the ducky generator instead. So everyone on the site is a custom duck. K-SASS prolly never expected his generator to be used anywhere. The requirement of this site is that it scales very well. I have db calls of 0.006s, this is for persistent data only and will be used by all site instances. I expect that it can handle many clients concurrent as long I do not return more than 30 rows or so. Events get handled by a self written pubsub server.

All sounds great and development goes fine. But why is this a rant? Because the same thing as always is biting me, I can't design a site at all. I know how but I don't have any feeling for design at all making me almost incapable of building an attractive site. The only thing I can 'design' is an application in bootstrap or smth. I spend so much time one design while I don't like to do it ironically. But looks of site is almost as important as an good working site. Good working site doesn't get used if looks bad in many casee. This is since the start of my career an issue and it sucks that I appearantly can't deliver a whole site on my own meeting my standards.

My backend work is top notch tho. Btw, this application is not to be an alternative for devrant. I do not think I can attract more users than it already has and I've seen two communities disappearing once because someone decided to make a new one, took half of community with him and both communities died after short while.

End product of this project is a working project, not a live site hosted somewhere. It's pure about mixing mostly self written tech to get the best performance. Reinventing wheel on many levels. I wanted maybe to do the site in C but decided that it's way to much work for the value. I change the site so rapid since I don't have decent plan that python aiohttp is the best choice in amount of writing it yourself and fast. It's very lightweight.

More a story than a rant, sorry

More masturbation with numbers.

If you take some product p,
and do

√p**(1/p)

and it's factors

a**(1/p)

and

b**(1/p)

you might find something interesting.

Take for example

a=21977
b=43331
p=a*b=952285387

(√p)**(1/p) = 1.0000000108551363

a**(1/p) = 1.0000000104986928
b**(1/p) = 1.0000000112115799

More often then not, a, b, or both, will share one or two of the most significant digits in the mantissa, as the root of p.

It doesn't always work, but it seems to be true more often than you might expect.

This is probably obvious in hindsight but I still think it's cool.

In some instances if you then do, say
sqrt(log(p, 1.000000010)), it comes pretty close to the original factors, but thats really hit or miss.

OK semi rant... Would like suggestions

Boss wants me to figure out someway to find the maximum load/users our servers/API/database can handle before it freezes or crashes **under normal usage**.

HOW THE FUCK AM I SUPPOSED TO DO THAT WITH 1 PC? The question seems to me to mean how big a DDoS can it handle?

I'm not sure if this is vague requirements, don't know what they're talking about, or they think I can shit gold... for nothing... or I'm missing something (I'm thinking how many concurrent requests and a single Neville melee even with 4 CPUs)

"Oh just doing up some cloud servers"

Uh well I'm a developer, I've never used Chef or Puppet and or cloud sucks, it's like a web GUI, not only do I have to create the instances manually and would have to upload the testing programs to each manually... And set up the envs needed to run it.

Docker you say? There's no Docker here... Prebuilt VM images? Not supported.

And it's due in 2 weeks...

TLDR: There's some days where the Gods of IT are not with you. Just lost a whole day of work.

So this morning, we (me and my team) big performance issues with our web app. Lot's of requests time out, big latency, etc

Try to ssh to VPS, latency of 10 seconds between user input and output.

Usual checks: RAM ok, Proc ok, hard drive ok, reboot server (20 minutes), update/upgrade

We decide to call OVH. After 15 minutes call, we try to reboot in rescue mode. Reboot fails at 60% + everything freezes.

After an hour, OVH opens an incident ticket on +200 vps instances (including mine) everything is down during +1h

Finally everything is okay ! Even had time to migrate my new database schema.

Still, quick heavy on the mind but feels good to go home with everything working out correctly

TL;DR: When picking vendors to outsource work to, vet them really well.

Backstory:
Got a large redesign project that involves rebuilding a website's main navigation (accessibility reasons).
Project is too big just for our dev team to handle with our workload so we got to bring a 3rd party vendor to help us. We do this often so no big deal.
But, this time the twist was Senior Management already had retained hours with a dev shop so they want us to use them for project. Okay...

It begins:
Have our scope / discovery meeting about the changes and our expected DevOps workflow.

Devs work Local and push changes to our Github, that kicks off the build and we test on Dev, then it goes to Staging for more testing & PM review. Once ready we can push to prod, or whenever needed. All is agreed, everyone was happy.

Emailed the vendors' project manager to ask for their devs Github accounts so we can add them to the project. Got no reply for 3 days.

4th day, I get back "Who sets up the Github accounts?"

fuck me. they've never used Github before but in our scope meeting 4 days ago you said Github was fine...??

Whatever, fuck it. I'll make the accounts and add them.

Added 4 devs to the repo and setup new branch. 40min later get an email that they can't setup dev environment now, the dev doesn't know how to setup our CMS locally, "not working for some reason."

So, they ask for permission to develop on our STAGING server.. "because it's already setup"... they want to actively dev on our staging where we get PM/Senior Management approvals?

We have dev, staging, production instances and you want to dev in staging, not dev?... nay nay good sir.

This is whom senior management wants us to use, already paid for via retainer no less. They are a major dev shop and they're useless...

😢😭

Cant wait for today's progress checkup meeting. 😐😐

Ok so I have done some work with crypto currency mining pools and recently a client requested for me to make a splash page that showed data from multiple instances of these pools APIs. I went to find some documentation for this open source api and to my surprise there is none. I thought of querying the public API from the clients side and it worked, however it's so slow that the data shows up roughly 20 seconds after the page loads.

Easy fix right? Make a PHP server get the data every 5 seconds, cache it and serve the data with the page and use a websocket for live updates! Until I found out that there is no practical way in this garbage framework to get the damn API data without making an HTTP request or mutilating the original source code. I'm so done with this garbage framework. It literally loads pages based on a page and action parameter on the index.php. I quit.

I used to work at a startup company that was so mismanaged that they lost track of when the Visual Studio licenses expire.

So during a critical week, the Visual Studio instances stopped working, and they have to scramble getting new licenses, which took a while.

In the end, the client lost confidence, pulled the plug on the project. I also lost confidence in the company and bailed out. Less than a year later the company went totally bankrupt.

That moment when you change your username because you a get a bit too paranoid of your stalker-ish manager finding you here

But i start to get why so many people want to divide their online footprint into as many instances as possible, the less is know, the less traceable you are

Do any of you have two browser instances for personal and work things? I do at least, and it's so annoying when I click a link and it opens in my personal browser instead of my work one.

So I made a script that I set as default browser that checks the link and opens the correct browser. Oh boy do I love Linux :D

1) Never be afraid to ask questions.

There are so many instances of situations where assumptions have been made that shouldn’t have been made, resulting in an oversight that could have been rectified earlier in a process and wasn’t.

Just because no one’s asking a question doesn’t mean you’re the only person who has it.

That being said, it’s really important to figure out how to ask questions. Provide enough context so that the audience for your question understands what you’re really asking. If you’re trying to troubleshoot a problem, list out the steps you’ve already tested and what those outcomes were.

2) When you’ve learned something, try to write about it. Try to break it down as though you were explaining it to a child. It’s through breaking down a concept into its most simple terms that you really know that you understand it.

3) Don’t feel like you have to code *all of the time*. Just because this is what you’re doing for a living doesn’t mean that you have to make it your life. Burnout is real, and it happens a lot faster if it’s all you do.

4) Find hobbies outside of tech!

5) Network. There are a number of great communities. I volunteer for and am a member of Virtual Coffee, and can vouch for that community being particularly friendly and approachable.

6) Don’t let a company pay you less than industry standard and convince you that they’re doing you the favor of employing you.

7) Negotiate salary. Always.

8) If you’re a career transitioner, don’t be afraid to talk about your previous work and how it gave you experience that you can use in programming. There’s a whole lot of jobs that require time management, multi-tasking, critical thinking, etc. Those skills are relevant no matter where you got them.

9) If it takes a while for you to get a gig, it’s not necessarily a reflection on you or your abilities.

10) Despite what some people would say, coding’s not for everyone. Don’t feel like you have to continue down a road just because you started walking down it. Life’s not a straight path.

I was talking to a friend about the current state of machine learning through tensorflow and commented about the use of Javascript as a language.

He discarded the idea as he views Javascript as something that should only be used as a frontend technology rather than something to build backends or deep learning models.

I am thorn. I have always liked Javascript but will admit that I have used it mostly in the area of front end with very few backend instances(i did create a full stack intranet app in Express once, major success for the application it was hosting, it was a very basic api which had its own nosql db with no need to interact with the company's relational data, it was perfect for the occasion and still help maintaining it from time to time)

My boi states that node's biggest issue has always been npm and the quality of packages. I always contradict those statements by saying that if one uses community standards and the best packages then one does not need to worry about the quality(i.e mongoose over some unmaintained mongo wrapper etc)

I sometimes catch myself finding that my way of thinking adapts better to JS than it even does Python (which is his preference for deep learning) and whilst there are some beastly packages for python in terms of quality and usefulness such as matplotlib etc that one can do great things with the equivalent JS.

I mean, tensorflow.js came from the same wizards that did tensorflow (obviously) and i find the functional approach of JS to be more on par with how we develop solutions.

I am no deep learning expert, and sadly I have no professional experience with machine learning. But I venture to say that we should not cast aside the great strides that the JS community has done to the language in terms of evolution and tooling. Today's Js is not your grandaddy's Js and thinking that the language is crippled because of early iterations of the language would be severely biased.

What do you guys(maybe someone with professional experience) think of Js as a language for machine learning?

Do you think the language poses something worth considering in terms of tooling and power for ml?

An anti-rant: I just made some code and out of nowhere it suddenly had an awesome feature that I didn't even program. No, not a euphemism for "bug", an actual feature.

Here's the story: A few months ago I made a shortcut for "System.out.println(…)" called "print(…)". Then I developed it further to also print arrays as "[1,2,3]", lists as "{1,2,3}", work with nested arrays and lists and accept multiple arguments.
Today I wanted to expand the list printing feature, which previously only worked for ArrayLists, to all types of List. That caused a few problems, but eventually I got it to work. Then I also wanted to expand it to all instances of Collection. As a first step, I replaced the two references to "List" with "Collection" and magically, no error message. So I tested it with this code:

HashMap<Integer, String> map = new HashMap<>();
map.put(1, "1");
map.put(2, "");
map.put(3, "a");
print(map);

And magic happened! The output was:

{1=1, 2=, 3=a}

That's awesome! I didn't even think yet about how I wanted to display key-value pairs, but Java already gave me the perfect solution. Now the next puzzle is where the space after the comma comes from, because I didn't program that in either.

I feel a bit like a character in "The subtle knife", who writes a barebones program to communicate with sentient elementary particles (believe me, it makes sense in context) and suddenly there's text alignment on the left and right, without that character having programmed any alignment.

The IT at my current work designed infra as such :
One repo for ALL the configs for every project and one config file per project that defines the version of the language (ex node 6) for all environment of a project. I don't even want to talk about deploying previous version or what happen when you update the version and AWS spawns new instances.
Jump into chatops hype approach and use one single script to deploy every app. Talk about a single point of failure but hey we use slack now it's great no?

Since I always think we are one character away from bad deployment and I'm into one click deployment then I've made a web app just to generate command and copy it or send it to slack.

I guess this is what happens when IT work for themselves only..

When your customer calls you out and asks why "such and such" data wasn't copied over to the other two instances.

Then, thinking of course that it must be my fault: *research begins*

Reply to customer:
Your boss sent me an email that listed data points to *not* copy over, the item in question being one of them.

BAM!! ....developers: 1 customer: 0

I bought this to serve Minecraft:
HP Z420 Workstation E5-1650 V2 Six Core 3.5Ghz 32GB 256GB SSD Quadro 600 Win 10

Adding 1TB 870 Evo for Linux. Gonna default boot to Linux. I am hoping to serve up a few instances of various modpacks. Minecraft is single thread so I wanted decent per core performance.

All total I spent about $450.

I'm so used to using IDEs that I'm expecting double tapped words to highlight other instances of the same words while browsing the web 😅

So I suck at scripts, windows scripts namely. I need a script to monitor a program on machine and send an email if it goes down. There are eight instances running on the machine and they can be determined to be working if a specific port is open, one port per instance. I have no clue where to start and I thought it could be done with some existing service or script. Suggestions?

TLDR: I need advice on reasonable salary expectations for sysadmin work in the rural United States.

I need some community advice. I’m the sysadmin at a small (35 employee) credit card processing company. I began as an intern and have now become their full time sysadmin/networking specialist. Since I was hired in January I have:

-migrated their 2007 Exchange server to Office 365

-Upgraded their ailing Windows server 2003 based architecture to 2012R2

-Licensed their unlicensed VMware ESXi servers (which they had already paid for license keys for!!!) and then upgraded them to 6.5 while preventing downtime on hosted VMs using tricky transfers and deployments (without vMotion!)

-Deployed a vCenter server to manage said ESXi servers easier

-Fixed a three month gap in their backups by implementing Veeam, and verifying its functionality

-Migrated a ‘no downtime’ fileserver to a new hypervisor host, implemented a ‘hot standby’ server as a backup kept up to date by the minute with DFS replication.

-Replaced failing hard drives in a RAID array underlying their one ‘business critical’ fileserver, which had no backups for 3 months at that time

-Reorganized Active Directory and Group Policy deployment from a nightmare spiderweb of OUs and duplicate policies

-Documented the entire old network and now the new one as I’ve been upgrading this

-Audited the developers AWS instances and removed redundant machines, optimized load balancing on front end Nginx servers, joined developer run Fedora workstations to the AD domain and implemented centralized syslog monitoring on them.

-Performed network scans and rewrote firewall exceptions to tighten security

There’s more, but you get the idea. I’ve now been tasked with taking point on an upcoming PCI audit which will be my first.

I’m being paid $16/hr US, with marginal health benefits. This is roughly $32,000 a year, before taxes.

I have two years previous work experience managing a third party Apple repair facility (SimplyMac) and every Apple certification for warranty repair and software troubleshooting. I have a two year degree in general sciences, with about 4 years of college credit (Two years of a physics education and two years of computer science after I switched focus) I’m actively pursuing a CCNA and MCSA server 2016 with exams paid for and scheduled.

I’m going into a salary negotiation in two months. What is a reasonable salary to request, from your perspective, for someone in my position?

Thanks in advance!

Don't need Netflix when you have a production deployment right before a long weekend. It has failed since last two weeks due to vulnerabilities present in one of libraries(P.S. FUCK JAVASCRIPT and Post release vulnerability scans!). You have rewritten the whole functionality from scratch twice! Security gates finally open for you, welcoming with arms wide open. So you click Deploy! DAFUQ!! FUCK MY LIFE! Deployment failed! It's only a 3 hour window to deploy! You frantically re-review your code, is it me?? Not again!! It isn't! Well, why is the deployment failing, you work against the clock. Going through configs, code, documentation! WTF is it?? Should I give up and raise a support ticket? Nope! You login to the server, sifting through logs and configs, there's a couple of other tickets with today's deadline. What are you going to do? And you get a hint! You take the hunch, change the config 5 minutes before deadline!
Get merge request approved, wait for the build, hit DEPLOY!! Nail biting 3 minutes! Your eyes fixed on the logs! Building..... Pushing instances..... Starting App..... SUCCESS!!! Finish the remaining tickets! Your long weekend still exists!

Hey! This is a followup to my last story.

TL;DR: I thinking of quitting my old job, got an offer at a startup, about the same pay, but much better working conditions.

First of all, the meeting with my lead. It was a performance report on her side to me, and I got 100 to 110% in performance in all points. My lead said "this team without you wouldn't be this team anymore" - which makes me feel a little bit bad for her if I decide to quit. She is a great team lead, but I don't belive the old company is worth my time anymore.

Now to the new company. Shortly after that performance report meeting, I had a call with the ceo, and what do I have to say besides: What a cool dude. He listened to me, asked me questions about my previous jobs (not just as programmer) and so on. But because first looks are deceiving, I went to their office last thursday. And wow. Their are exactly what I imagined them to be. Cool, young folks, 100% tech enthusiasts, and open minded.

One of the new hires in the new company wanted a 6 months internship between his studies. Instead they offered him a full time job - for the 6 months. They even offered me to pay back my scholarship that I will own my old company for leaving early. This is awesome.

The only things that will be worse than my old job are, that I have to negotiate payment instead of yearly increases, 4 days less paid vacation, so only 26 days, and 40h weeks. And they have no workers council, which isn't good, but it's not the worst either.

I got them fixed on 57.000€, not including an up to 10.000€ annual bonus. The way you achieve your bonus seems good to. It's split in two parts, internal and external bonus. Internal bonus is when you engage with internal events like tech calls, sharing your knowledge on your main IT topics, etc. External Bonus is a bit more complicated, but also straight forward. You work on projects for customers, and if you have less than 3 weeks a year that you dont participate in an project, you get the full bonus.

Last friday, I filed a request for a certificate of employment from my current team lead, this is odd for her because I have never done it before, and she asked why I requested it. I said to her that we can talk about it, and she agreed but didn't call me, yet.

Lastly, another good friend of mine will be employed by my team soon, but for a fraction of the payment that I currently receive! He is doing the exact same work, and even worse, he is doing project managment for his main developer project too! And is getting less paid... I just cant...

Yesterday we needed to update a few cloud instances, the only other person who knows about setting up CICD and our OpenShift Containers than me is only in part time and works two days a week, his trainee didn't know anything, so it's up to me. This isn't hard or anything, but it shows that this system our mangement maintains will fail soon, maybe even with me going? I sure hope so tbh.

One of you guys said, I should go to my team lead and negotiate a higher pay, but the truth is, that because we are a big ISP we have an collective agreement for payment and are grouped by tasks (which is bull shit btw, because I'm doing tasks much higher paid than currently). This also means that I cannot simply jump in another group, and can only increase my current pay to about 115%, which is done automatically every year by 5% up to 115%. Anything above is considered extra, but I don't think they will go with it.

I will decide this week about my future at the old company, but I really don't know what to do...

Another fun thing. This morning one of the first mails i read was a issue about a bug in our software.

This was a bug i mentioned months ago but there was nog evidence where i searched like mails chats or tickets.

If people would just listen to me this bug was solved months ago but back then i got a reaction like: "works over here" while i tested it on two different instances with buggy results each time.

Oh my, never was i triggered more. Of course i can only speak for my experience. I study software development as focus.

First off, the starting languages and or concepts you learn.
Why the fuck do they start with java and don't even really explain how instances actually work? Of course they don't. Because it would be way too fucken much for a semester to go over garbage collection, Instanciation of stuff, allocation in such an advanced system, etc..
How about starting with something not 50% managed by a vm?
Good ol' C. And now don't tell me thats a rough start. We all know about these subjects or exams where it's all about sorting people out. Who will be able to manage a whole bunch of shit or who should consider something else.
Yo dawg sick idea: how about sorting it via the will to achieve the skill of coding?
Nah but we make the exams around coding (by the fucking way done on paper, what the hell) such a fucking breeze, asking you how to convert hex do dec.
Meanwhile maths will make you cut yourself in a dark corner, after you nearly shot yourself because of some lame-ass business-subject.

This senior engineer had this kid spend most of a day tracing down all of the instances of a certain variable so they could make heavy changes to the software. We work under a change management system of course and all of this led to two weeks of work outside of any of this. The senior engineer ended up 🔥 and the kid very close.

I'm still trying to figure out what makes someone do something like that knowing the outcome.

Rebooted the two oldest EC2 instances in our network today. It went as badly as expected. They were supposed to be identical

* One server rebooted perfectly
* Second server rebooted with data loss, permission issues, configuration failures.

What the fuck is this steaming shit!?
You fucking background apps, chrome and Firefox take all my resources to fucking open my Google drive?!

AND WHY THE FUCK ARE THERE 19 INSTANCES OF CHROME RUNNING!!!!

WHY THE FLYING FUCK DO YOU NEED TO DO THIS! LET THE FUCK LOAD!

I HATE WINDOWS! BUT THEN THERE ARE APPS WHO ARE FOR WINDOWS AND MAC ONLY!

I'M DYING NOW!!!!!!!!

FINE! EAT ALL MY 12 GB RAM AND FUCK YOURSELF IN THE CORNER BUT PET ME DO MY WORK!

Is the CS field creating terms for the sake of creating terms?

Someone mentioned a "closure" in another post. I instinctively knew what they meant by that based upon the code I saw. I had heard the term thrown around before, but it had not yet connected in my mind. I wondered why I had not been exposed enough to care.

So I thought: What does C++ have as far as closures?

I found that C++ has lambdas. Those are definitions for function objects. They do not exist at runtime. But a closure does. The analog is you have classes. They are definitions and do not exist at runtime. But instances of classes do. So at runtime the instance is what you are working with. This is the same as lambdas vs closures in C++. The closure is the runtime counterpart. Why a separate term for what essentially is an instance? Is it because it captures data and code? As far as I know the closure is all data that gets passed around that calls a function. So it is essentially an instance of a lambda.

Another term: memoization. I have yet to see this added to any dictionary in online tools like a browser. Is the term so specific that nobody cares to add it? I mean these are tools programmers use all the time.

My guess is these terms originated a long time ago and I have just not been exposed to the contexts for these terms enough. It just seems like I feel like I have been in the field a long time. But a lot of terms seem alien to me. I also have never seen these terms used at work. Many of the devs I work with actively avoid CS specific terms to not confuse our electrical coworkers. My background started in electrical. So maybe I just didn't do enough CS in college.

I don't like when

you have a couple of years of experience with some language and you're like "I should read a good book about it, and have some proper solid foundation instead of playing by ear".

So you get a book and what follows is a very jarring experience.

Because for the first 8 chapters they get into the basics of the language.

You're occasionally like "interesting, I did not know that".

But for the most part you're like "yes, for fucking christ I know that, everybody knows that",

or you complain about the author being redundant,

or about the outdatedness of the book, since most documentation is now in the interwebs

or you reach flawed conclusions out of frustration like "this isn't making me any money, I could get on upwork, or do some bounties instead of wasting time on this"

then you start to skim through the pages like "I know this, and this, and this" until you realize you're in some page you have no fucking idea what it's talking about, as if you ended up on the wrong side of town

so you start backtracking (frustration is going critical at this point)

but backtracking is annoying because it's not well defined where you stopped getting it, as if in page 33 you were getting it 100%, but 0% on page 34, it's more like a gradual, irregular decrease,

so you have no idea where to start re reading from.

you just shove that shit into the wall at that point.

Some of these are learning discipline problems.

I guess there are ways to mitigate them, such as writing down questions of things not understood, co reading, etc.

But the one thing I don't think I can't get past is when authors write like shit,

like being redundant, using different words to say the same shit

or using confusing sentences that can mean different things at the same time,

or using the incorrect terminology, eg: if I were teaching OOP, saying shit like "classes create objects" but later on saying something like "classes create instances".
They usually nail the definitions the first time, but then use different terms for the same thing. It's shit.

And I think that's a writing culture that I hate.
From school you are taught to bot repeat words.

To say the same shit in different ways.

To be descritive, but vague.

That's absolutely shitty for programming in my opinion.

Why is it that the tech Youtubers of this world (and tech reviewers in general) tend to completely skip development as a use case, and instead (if they do ever move off gaming) focus on things like Rendering & Modelling / CAD work? I'm sure there's *way* more devs in the world than CAD guys, surely?!

And if they *do* give it the light of day, it's always a quick benchmark based on "Firefox compile time", "Linux kernel compile time" or similar. Dude, it's 2020. Much as some would like to believe otherwise, most guys stopped compiling swathes of heavy C & C++ as part of their normal workflow over a decade ago.

Real-world tests I want to know about are things like docker performance, common IDE startup performance, compile performance of different sized applications on a bunch of langs like Kotlin, C#, Java, Clojure - or node.js performance, Tensorflow performance on NVidia's vs AMDs latest GPUs, etc. I care about how many IntelliJ instances & VMs I can have open way more than how many Chrome tabs I can forget to close.

But noooo - forget that, here's how fast Blender can render a BMW! 😬

I’m really bad at closing my tabs. I’ll often have 40+ tabs open when tackling some sort of problem or when doing research. Sometimes I’ll crack open another browser instance to research something unrelated. I use a tab session saver to save all of my instances before a reset. But the funny part is, I almost never go back into my stored sessions. I’ll just open up a fresh browser after restarting and the cycle begins anew.

I need help.

One of biggest epiphanies came through this fundamental critique in SICP of the assignment operator. Through years of imperative programming it seems so innocent, doesn't it? But that you lose referential transparency, run into the alias problem and fundamental difficulty to determine object equality (or of their instances) - that was kind of eye opening considering all the pain I had already experienced with state in concurrency.
(It led me so far to think it's an ontological issue, that even in the discrete computing universe we have not come so much further than Zenon's paradoxa on change.)

How would you support multiple versions of an API and why?

- Multiple version instances behind a load balancer.
- Versioned controllers behind a proxy.

Curious to hear yours thoughts and reasoning.

A large pool of application instances' is writing logs to the same physical file. No way to distinguish which instance wrote which line.

Welcome to hell

We're being asked questions. We're replying that we cannot help unless logging is fixed. Noone's bothering to fix this mess and instead returns tickets with requests to investigate more.

F.U.N
/s

I'm absolutely exhausted...
Just spent the past 2 days restructuring our SAAS products entire server network on AWS just so we can have a static IP address for all our server instances passing through an NAT....because we need to integrate with another service that only allows you to access their API if they whitelist your IP.

participating at an coding challenge.

the mission is to write an game solver for an game engine - in java. based on astar, pathfinding should be made possible by cloning objects.
never seen a so hardly misconcepted challenge, where character instances and their variables are static and contain uncloneable data😂 oh god what a waste of time realizing this bs

Small chaotic startup that never grew up (15 years atm).
Hosts/maintains a number of apps/sites for various customers.

At some point, someone decides that a CMS would be usefull to maintain the content across all products. Forgoing all sense, reason and the very notion of "additional maintenance and dev" it is decided that one should be built in-house.

Fast forward a number of years.

Ops performs routine maintenance on prod-servers. A java-patch accidently knocks out one of the pillars a 3rd party lib the CMS uses for storing images. CMS basically burst in to flames causing a.... significant incident.

Enter yours truly to fix the mess.
Spend a few days replacing the affected 3rd party lib. Run tests on CMS in test and staging environments. Apply java-patch. All seems fine.

When speaking to frontenders and app-devs, a significant hurdle present itself:
All test/staging instances of all websites/apps/etc ALL USE PRODUCTION CMS. Hardcoded. No way around.

There is -no- way to properly test and verify the functionality of any changes made to the home-brewed CMS.
My patch did indeed work in the end.

But did the company learn anything? Did they listen to my reasoning, pleading or even anguished screams for sanity?

No.

1, Visual studio shouldn't slow down after opening 3-4 instances

When the CTO/CEO of your "startup" is always AFK and it takes weeks to get anything approved by them (or even secure a meeting with them) and they have almost-exclusive access to production and the admin account for all third party services.

Want to create a new messaging channel? Too bad! What about a new repository for that cool idea you had, or that new microservice you're expected to build. Expect to be blocked for at least a week.

When they also hold themselves solely responsible for security and operations, they've built their own proprietary framework that handles all the authentication, database models and microservice communications.

Speaking of which, there's more than six microservices per developer!

Oh there's a bug or limitation in the framework? Too bad. It's a black box that nobody else in the company can touch. Good luck with the two week lead time on getting anything changed there. Oh and there's no dedicated issue tracker. Have you heard of email?

When the systems and processes in place were designed for "consistency" and "scalability" in mind you can be certain that everything is consistently broken at scale. Each microservice offers:

1. Anemic & non-idempotent CRUD APIs (Can't believe it's not a Database Table™) because the consumer should do all the work.
2. Race Conditions, because transactions are "not portable" (but not to worry, all the code is written as if it were running single threaded on a single machine).
3. Fault Intolerance, just a single failure in a chain of layered microservice calls will leave the requested operation in a partially applied and corrupted state. Ger ready for manual intervention.
4. Completely Redundant Documentation, our web documentation is automatically generated and is always of the form //[FieldName] of the [ObjectName].
5. Happy Path Support, only the intended use cases and fields work, we added a bunch of others because YouAreGoingToNeedIt™ but it won't work when you do need it. The only record of this happy path is the code itself.

Consider this, you're been building a new microservice, you've carefully followed all the unwritten highly specific technical implementation standards enforced by the CTO/CEO (that your aware of). You've decided to write some unit tests, well um.. didn't you know? There's nothing scalable and consistent about running the system locally! That's not built-in to the framework. So just use curl to test your service whilst it is deployed or connected to the development environment. Then you can open a PR and once it has been approved it will be included in the next full deployment (at least a week later).

Most new 'services' feel like the are about one to five days of writing straightforward code followed by weeks to months of integration hell, testing and blocked dependencies.

When confronted/advised about these issues the response from the CTO/CEO
varies:

(A) "yes but it's an edge case, the cloud is highly available and reliable, our software doesn't crash frequently".
(B) "yes, that's why I'm thinking about adding [idempotency] to the framework to address that when I'm not so busy" two weeks go by...
(C) "yes, but we are still doing better than all of our competitors".
(D) "oh, but you can just [highly specific sequence of undocumented steps, that probably won't work when you try it].
(E) "yes, let's setup a meeting to go through this in more detail" *doesn't show up to the meeting*.
(F) "oh, but our customers are really happy with our level of [Documentation]".

Sometimes it can feel like a bit of a cult, as all of the project managers (and some of the developers) see the CTO/CEO as a sort of 'programming god' because they are never blocked on anything they work on, they're able to bypass all the limitations and obstacles they've placed in front of the 'ordinary' developers.

There's been several instances where the CTO/CEO will suddenly make widespread changes to the codebase (to enforce some 'standard') without having to go through the same review process as everybody else, these changes will usually break something like the automatic build process or something in the dev environment and its up to the developers to pick up the pieces. I think developers find it intimidating to identify issues in the CTO/CEO's code because it's implicitly defined due to their status as the "gold standard".

It's certainly frustrating but I hope this story serves as a bit of a foil to those who wish they had a more technical CTO/CEO in their organisation. Does anybody else have a similar experience or is this situation an absolute one of a kind?

Least successful...

In a nutshell, an multi version http client for a elasticsearch.

It supported ES 1.7 up to v7.

With an reduced future set, but all in all it allowed doing everything ES offered - just not for one version, rather the whole monty.

For various reasons I wasn't allowed to opensource that...

Which brings me to the least successful part. The client is a beast and would be a blessing for a lot of people I'd guess, but it's sadly covered by more legalese than one could imagine.

Think of legalese as in "Angel - Wolfram and Heart" legalese. I wouldn't be surprised if some part of the contract was written in blood.

... And least successful as in: Nope. Never gonna do that again.

Abstractions necessary for supporting multiple versions are are really painful.

Having an E2E test suite consuming > 64 Gigabyte of RAM for testing against several ES docker instances in parallel isn't fun.

Nothing of that project was fun.

Still gives me nightmares.

(NDA expired short time ago)

wow office is full of pessimistic and unhappy people. being a covid graduate i didn't knew the sadistic life of office goers . can some of you pre covid people share instances of a positive ofice environment that made you go to office each day?

## Learning k8s

Okay, that's kind of obvious, I just have no idea why I didn't think of it..

I've made a cluster out of a rpi, a i7 PC and a dell xps lappy. Lappy is a master and the other two are worker nodes.

I've noticed that the rpi tends to hardly ever run any of my pods. It's only got 3 of them assigned and neither of them work. They all say: "Back-off restarting failed container" as a sole message in pod's description and the log only says 'standard_init_linux.go:211: exec user process caused "exec format error"' - also the only entry.

Tried running the same image locally on the XPS, via docker run -- works flawlessly (apart from being detached from the cluster of other instances).

Tried to redeploy k8s.yaml -- still raspberry keeps failing.

wtf...

And then it came to me. Wait.. You idiot.. Now ssh to that rpi and run that container manually. Et voila! "docker: no matching manifest for linux/arm/v7 in the manifest list entries."

IDK whether it's lack of sleep or what, but I have missed the obvious -- while docker IS cross-platform, it's not a VM and it does not change the instructions' set supported by the node's cpu. Effectively meaning that the dockerized app is not guaranteed to work on any platform there is!

Shit. I'll have to assemble my own image I guess. It sucks, since I'll have to use CentOS, which is oh-so-heavy compared to Alpine :( Since one of the dependencies does not run well there..

Shit.

Learning k8s is sometimes so frustrating :)

- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite

All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.

Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.

New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.

I'm not even dreading writing basic syntax highlighting!

Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.

Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.

Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.

Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).

Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.

The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.

I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.

Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.

I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.

My companys custom logging library is not thread safe and has problems with multiple instances of the endproduct as well.

Identical configuration.
Application won't find proper base URL locally.
Application will find proper base URL on test and prod instances.
Excuse me, what the FUCK?

Shit bathed and stack smashing ass loads of fuck.

I wrote a virtual machine, and just to fuck myself harder, I make the decision of applying some fancy dumbass theories of mine. This translates to a piece of shit modular design that works exactly as intended, but constantly gives me vietnam flashbacks to the horrifying, multiple concurrent instances of my younger mind being incessantly turbo-raped by the dozen object-obsessed pedophiles that I initially studied under.

Now, were they *actual* pedophiles? No, of course not. But I have to make fun of the acronym somehow and that's what came to mind, leaking horse dung all over the walls, floor, curtains and carpets.

Anyway, I feel so smart after this traumatic experience I just have to keep doing it to relive the terror once again. Find me in the corner, laying down in the fetal position, sobbing until the tears build up and drown me in this well of despair, or rather this finely shit painted portrait of a toilet in a lonely and stinking unisex public bathroom stall.

But let me squeeze these fucking tits a little bit harder, because that's my actual day job. That's right. I get PAID for slapping around mammary glands, it's not much but it's an honest living.

So where was I? Ah, yes, absolute degeneration. I'm truly the Max Wright of programming, mostly for smoking crack and having unprotected sex with homeless people, but also for keeping alien life forms in my basement that go out at night to hunt for sweet feline delight.

But as I keep going, I decide I want a language for the machine so I don't have to punch bits by hand all fucking day like an idiot, so alright let's make a small assembler for this shit... oh, right, except it's not small, because gently suckle the bile out the lips of my fucking butthole.

I may redefine a load of shit two months down the line, so I have to make everything perfectly encapsulated and easily fucked with -- which in my licking vomit off the floor of a porn theater travesty of a case means I'm generating half the code and scrambling as hard as I can to glue everything together.

Does it work? Of course it works, I'm Max Wright bitch. I can redefine the ISA all I want, anytime I want without breaking anything because of my pristine crackhead encapsulation. And to credit the scrambled eggs I have for fucking brains, it's not even *that* complex.

The problem is I keep forgetting shit, not how it works, just that it's there. So I forget that I have a virtual machine, and I forget that I have an assembler, and so I spend an entire day trying to figure out how the fuck I'm going to handle a loop inside an unrelated interpreter.

By the time I manage to remind the drooling undead jackass that is this husk that my irredeemably demonic self inhabits, that we can easily solve this by using the tools we've already built, it's so late and we're so tired there's not much we can do. All this time, WASTED.

So I promised a post after work last night, discussing the new factorization technique.

As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.

697 becomes -> 600, 90, and 7.

It then factors *those* to give a decomposition matrix that looks something like the following when printed out:

offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]

offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]

offset: 1, exp: [[Decimal('7'), Decimal('1')]]

Each entry is a pair of numbers representing a prime base and an exponent.

Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.

So for offset three (600) here, we're looking at

2^3 * 3 ^ 1 * 5 ^ 2.

But actually we're searching

2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1

etc..

On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.

And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.

So by implication we can filter out any product of this exponent search that is greater than the square root of n.

Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.

Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.

And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.

It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.

But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.

For example, for one particular semiprime n=pq, this was some of the data:

n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]

q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]

It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.

And I found this rule held each time I tested it.

Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.

I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.

This was ripe for a decision tree generated through random search.

Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]

n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]

Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]

And so it was clear from the get go that this approach held promise.

From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.

It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.

Christe on a bike, why would anyone sane use PowerShell? I can't even run my own fucking script, because "cannot be loaded because running scripts is disabled on this system". Even tho I used the same script file literally yesterday.

So I'm just gonna use single command to change it. Easy? Well fuck no! Because no one thought that implementing something like "sudo" would be a fantastic idea, so you have to jump between two separate instances of that piecie of shit. Not to mention it takes ages to even load it.

WARNING - a lot of text.
I am open for questions and discussions :)

I am not an education program specialist and I can't decide what's best for everyone. It is hard process of managing the prigram which is going through a lot of instances.
Computer Science.
Speaking about schools: regular schools does not prepare computer scientists. I have a lot of thoughts abouth whether we need or do NOT need such amount of knowledge in some subjects, but that's completely different story. Back to cs.
The main problem is that IT sphere evolves exceedingly fast (compared to others) and education system adaptation is honestly too slow.
SC studies in schools needs to be reformed almost every year to accept updates and corrections, but education system in most countries does not support that, thats the main problem. In basic course, which is for everyone I'd suggest to tell about brief computer usage, like office, OS basics, etc. But not only MS stuff... Linux is no more that nerdy stuff from 90', it's evolved and ready to use OS for everyone. So basic OS tour, like wtf is MAC, Linux (you can show Ubuntu/Mint, etc - the easy stuff) would be great... Also, show students cloud technologies. Like, you have an option to do *that* in your browser! And, yeah, classy stuff like what's USB and what's MB/GB and other basic stuff.. not digging into it for 6 months, but just brief overview wuth some useful info... Everyone had seen a PC by the time they are studying cs anyway.. and somewhere at the end we can introduce programming, what you can do with it and maybe hello world in whatever language, but no more.. 'cause it's still class for everyone, no need to explain stars there.
For last years, where shit's getting serious, like where you can choose: study cs or not - there we can teach programming. In my country it's 2 years. It's possible to cover OOP principles of +/- modern language (Java or C++ is not bad too, maybe even GO, whatever, that's not me who will decide it. Point that it's not from 70') + VCS + sime real world app like simplified, but still functional bookstore managing app.
That's about schools.

Speaking about universities - logic isbthe same. It needs to be modern and accept corrections and updates every year. And now it depends on what you're studying there. Are you going to have software engineering diploma or business system analyst...
Generally speaking, for developers - we need more real world scenarios and I guess, some technologies and frameworks. Ofc, theory too, but not that stuff from 1980. Come-on, nowadays nobody specifies 1 functional requirement in several pages and, generally, nobody is writing that specification for 2 years. Product becomes obsolete and it's haven't even started yet.
Everything changes, whether it is how we write specification documents, or literally anything else in IT.

Once more, morale: update CS program yearly, goddammit

How to do it - it's the whole another topic.

Thank you for reading.

I wonder what is going on in the minds of inexperienced developers. It must be very interesting.

I just read this bit of code
The task was to implement a certain schema into a database. They were given an ORM library, and several tutorials explaining what an ORM was and how it did it.

The result were these 3 models:
- A defaultUser with all of the defaults values for the User model. It wasn't even supposed to be instantiated, just accessed by `defaultUser.fields.username.default`
- another default table for another model.
- The "main" model, containing all other models in the form of JSON fields that would contain an array with other JSON objects that would represent the instances themselves.

I will say though, they made a home-brew ORM with (most of) all the logic a normal ORM has by parsing through the "main model", except, of course, common sense

I once baffled a colleague by showing him that you don't have to (and shouldn't!) use memcpy to copy struct-instances into a different variable in C, which in turn baffled me.

Good times!

What to do if someone asks for your help with problem X, but then you figure out they originally tried to fix problem A and recursively came up with bad solutions until they got at X at which point the entire codebase overlaps responsibilities, implementations leak, concrete instances are created in controllers ignoring DI and you just can't say ANYTHING nice about it?

Also does not follow a methodology and just does whatever, thinks singletonning a database context is a good option because stuff isn't saved, says they will 'refactor later' even though it should have been done last week and just doesn't seem to get it?

I've told them that what they're doing is plain wrong and they're making it harder for themselves than it needs to be, but they just seem to not get it, even though at this point basic stuff like that shouldn't be an issue.

Posted this in rant since it became kind of a rant instead of a question

Launch modes in Android?

Standard: It creates a new instance of an activity in the task from which it was started. Multiple instances of the activity can be created and multiple instances can be added to the same or different tasks.
Eg: Suppose there is an activity stack of A -> B -> C.
Now if we launch B again with the launch mode is “standard”, the new stack will be A -> B -> C -> B.
singleton: It is the same as the standard, except if there is a previous instance of the activity that exists in the top of the stack, then it will not create a new instance but rather send the intent to the existing instance of the activity.
Eg: Suppose there is an activity stack of A -> B.
Now if we launch C with the launch mode as “singleton”, the new stack will be A -> B -> C as usual.
Now if there is an activity stack of A -> B -> C.
If we launch C again with the launch mode as “singleton”, the new stack will still be A -> B -> C.
SingleTask: A new task will always be created and a new instance will be pushed to the task as the root one. So if the activity is already in the task, the intent will be redirected to onNewIntent() else a new instance will be created. At a time only one instance of activity will exist.
Eg: Suppose there is an activity stack of A -> B -> C -> D.
Now if we launch D with the launch mode as “single-task”, the new stack will be A -> B -> C -> D as usual.
Now if there is an activity stack of A -> B -> C -> D.
If we launch activity B again with the launch mode as “single-task”, the new activity stack will be A -> B. Activities C and D will be destroyed.
SingleInstance: Same as a single task but the system does not launch any activities in the same task as this activity. If new activities are launched, they are done so in a separate task.
Eg: Suppose there is an activity stack of A -> B -> C -> D. If we launch activity B again with the launch mode as “single instance”, the new activity stack will be:
Task1 — A -> B -> C
Task2 — D

I've done it! I've implemented a new feature. I call it, wheal. its just like the wheel you know and love, in every way, shape, and form. But now, you can take comfort in knowing the state of the art has surely progressed, every time you go to reference, "wheal". This has the added benefit that others who may already be familiar with wheels, will have no trouble at all coming to terms with wheals. Just please, do not make reference to wheels, or your software will not compile. And also be sure to annotate all instances of wheals *wheals are just like wheels!* until all devs have been on-boarded.

The conversations that come across my DevOps desk on a monthly basis.... These have come into my care via Slack, Email, Jira Tickets, PagerDuty alerts, text messages, GitHub PR Reviews, and phone calls. I spend most of my day just trying to log the work I'm being asked to do.

From Random People:
* Employee <A> and Contractor <B> are starting today. Please provision all 19 of their required accounts.
* Oh, they actually started yesterday, please hurry on this request.

From Engineers:

A developer couldn't get a application performance monitoring (APM) tool to trace his application. They claimed that their libraries and their configurations were alright and that the APM tool was non-performant.

The developer then argues with sysadmin that the APM tool can't trace the application and that there's nothing wrong with the application or the configurations. When sysadmin questions whether the developer got the tool to work anywhere, they say, "No" and head off to make it work at least in one place. They come back saying that it works on their development environment (which is their local machine). Sysadmin claims that the system configurations on the server instances cannot be matched by the development environment and there could be a lot more factors to be considered for the problem. The sysadmin asks to prove it on a server instance on one of the test environments and then they'd agree that it is a problem with the tool. They also argue that this is not the only application that uses the APM tool and the tool happily traces other applications with no issues.

The developer tries the same configuration on a staging instance and fails. In order to make it work, they silently uninstall the existing version of the APM tool and then compiles an unstable branch of the tool. It finally works with this version.

They go back to the sysadmin and show that it works on the staging environment, but does not on production. After banging their head on the wall for a while, the sysadmin figure that the tool had been swapped out for the unstable branch that was manually compiled. When questioned, the developer responds, "It works with this version on staging, so deploy the same version on production"

WTF? You don't deploy an unstable branch to production. Just because you can't make it work on the stable branch doesn't mean that it is the problem with the tool itself. There's a big difference between a stable branch and a non-stable branch. How would you feel if the sysadmin retorted by asking you to deploy the staging branch of your application to production?

Interesting...

On Friday, I was playing with the ChatGPT integration in DBeaver. I was using the DBeaver sample SQLite database. This database has a couple of tables, among them Album and Artist, where Album has a foreign key into Artist.

So, I asked it:

"give me a query that lists all albums from artists who's name starts with s"

The query I got back was:

SELECT * FROM Album

Uhh, okay.

But then, I noticed that I wrote "who's" instead of 'whose', which would be proper grammatically. So, I changed that, and then I got this query:

SELECT * FROM Album WHERE ArtistId IN (SELECT ArtistId FROM Artist WHERE Name LIKE 'S%');

Hooray, that works! I'm not sure it's the best way to write the query... I might have written:

SELECT * FROM album a, artist r WHERE a.artistid=r.artistid AND r.name LIKE 'S%'

...I'd have to check to see if one performs better than the other, and consider which syntax I find clearer, but that's a separate issue, it's just nice to see a working, reasonable query generated because that's the point, after all.

But I found it interesting that such a minor error would cause it to not work, that's my main point.

Interestingly, it seems to have learned: I just tried the same thing, and I got the right query either way. So that's pretty cool.

It's a pretty neat feature and I can see some legitimate value in it. I'm pretty good writing SQL myself... I've managed to write some truly hideously complex queries over the years... but there are definitely instances I can recall where the query didn't seem obvious at the start, and having an AI that can MAYBE produce something that is AT LEAST a starting point is definitely something I can get onboard with.

Dear god, tried to explain to my mum how to use a computer. Wait for spring creators update...😓
Everything went ... decent: learn opening different windows, closing them again, explaining functionality, which areas/buttons/etc.. are interactive ... and then comes the browser with its tabs😓
the only program which can open multiple "instances" of itself ... in itself. How to explain that? (i know that's probably not correct but that's the only way i can explain it) Needless to say she hasn't figured out how to use broswer tabs and what they are there for.
An now "Sets" come to windows. Oh boy how to teach that...?😥
... I'll probably just never show her just to keep safe😅

Hi people first as you know my English is not very poor im sorry for that.
I try to make an automat a sprinkle water and a auto light on a interior garden in aquarium.

For that in python i use main thread, a class Water.py extends Threading and Light.py extends Threading

In the __init__.py file i put my main function that get argv for execution. One of my arguments is -v (--verbose)
I want to pass that args to my class instances.

-I don't want to make one parameter in my constructors because I think we don't passe verbose mode in parameter of constructor.

-I use global not working through de import.

Do you have some magic for me :/ ?

load balanced three micro nodejs instances with Apache in my local system. load performance improved by 50% straight.

A way of running Minecraft servers on AWS and automatically hibernate instances when there are no players online.

I really don't like this trend of building command line applications for controlling some <buzzword> cloud app or <buzzword> framework.

Why should I need or want to learn the exact wording of your gcloud command, or the path to your Ng cli, or some ass-backwards AWS search syntax when I can get the same functionality from your web app, where I can use my FUCKING EYES to work out where the "Create Instance" button is and how to click it!!!??

Stop pushing your shitty python monolith of a client where possibilities for the above task range from:
- google-cloud instances --add "subfjfechye thiq"
To
- gcloud /create /type=INSTANCE "rogdhyuffhue"

"BuT iT mAkEs iT MoRe aUtomaTaBLe"
I DON'T CARE. What is the point when I can use a proper programming language instead of bash, with actual code-completion and syntax rather than the horrendous excuse for a suggestion system that is the Tab key where it probably doesn't even work in the first place and I have to copy and paste some mysterious dbus command buried in an old documentation page on the Wayback Machine using a utility I don't have installed and a broken URL?

Go away.

Idk why but this morning I was thinking about this high school elective class where we learned Adobe flash. But specifically 2 instances where I ignored the teacher and did my own thing

1. We were using Sprite sheets and he had us use photoshop to cut out the Sprite to a different layer and manually save each Sprite one by one to disk to use in flash. Some sheets had 50 fucking sprites
So I found a script for Adobe (action script I think they called their Javascript derivative) that exported every layer for me without all the manual clicking. There is probably an even better way. But this worked for how lazy I was back then

2. Our final projects we could do anything but he suggested not doing anything too complicated cause of time constraints and he barely taught is the scrptinh language for Adobe flash so making flash games was almost out of the question.
Me being stupid really wanted to make a working pong game. So I spent too long watching a German (i dont know German) tutorial video I found, and troubleshooting outdated code from that video. And improving things where I could with my limited knowledge made worse cause I wasn't interested in programming and didn't start learning python until the following year

Yeah don't know why I was thinking about those. But I feel it's a good perspective on how far I've come. From hacking together a pong clone with no skills, to being hired to automate and optimize processes and legacy projects

I hate the elasticsearch backup api.

From beginning to end it's an painful experience.

I try to explain it, but I don't think I will be able to cover it all.

The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)

The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.

Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots

Workaround... Create many repositories as each new repository forces an full backup.........

The second thing: ES scales. Many nodes / es instances form a cluster.

Usually backup APIs incorporate these in their design. ES does not.

If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.

It might sound not so bad with 12 nodes and one index...

But it get's pretty bad with 100s of indexes and several dozen nodes...

And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.

So traffic shaping must be manually added. Yay...

The last thing is the API itself.

It's a... very fragile thing.

Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.

Documentation != API != Reality.

Especially the fault handling left me more than once speechless...

Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS

Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.

And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).

So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...

Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.

So much joy and fun, isn't it?

Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.

PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.

I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.

Changing instances to arrays. So we've all had this issue:

Option 1 was the most flexible and abstract option where a lot of functionality could be built on this.

Option 2 was the fastest solution, that would solve only specific problems.

The whole Agile philosophy points to option 2. The problem is that clients will always want to add that functionality in option 1, and changing requirements makes us lose time, the precious resource that managers supposedly cherish, yet they always want us to choose the fast option.

We're at that point where the client wants to add functionalities, but since we already built with the previous requirements in mind. Ugh.

Changing instances to arrays.

TLDR: Why the fuck is a senior developer creating multiple instances of a core piece of logic all over the fucking application?!?!?!?

Context: I am also a senior dev, and have worked with this guy for years. He has even completed me on my clean code practices and architecture, so I really cant understand why he would copy and paste a public class into 3 other models on the project instead of just referencing the original. I’m just posting this hear as my version of screaming into a pillow in frustration, and to avoid badmouthing him to co-workers.

A truly scary multiplayer gothic horror action RPG set in a Victorian world with a Lovecraft inspired story (already got the story written as it so happens) with multiple mutually exclusive but tightly linked story lines. That is to say you can experience only one part of the unfolding story with the player having to communicate and interact with others in the game world to discover the full horror of the world.

The world would not have instances the world would be in a state that players find it in, based on what other players had done.

I have a lot of the game mechanics thought out, but time and money... If only it were limitless...

i might not have ssh access to live instances but i can redirect live traffic to test instances and debug my shit there!

... no but i really do that

Be me half asleep wondering if the other instances of me will be able to figure out the solution... Suddenly I realize I'm the only me. Shit. Wtf have you done to me programming!?

Hey guys (and girls (and people who dont identify as either of them)),

As some people here might know I am currently in the planning phase of an open source alternative for Thingiverse. After gathering information on multiple platforms Ive heard people really wanting it to be decentralized (a bit like Mastodon).

I really like that idea and thus want to implement it, does any of you have experience or knowledge of decentralized systems programming? I have trouble getting information on how this works. If someone is willing to help me explain a few things like "How does one instance retrieve data from other instances? How does it know a new instance is running somewhere?"

So if anyone knows a great source for information or can and wants to help me via a chat session please respond below

Trying to get HIPPA compliance, and wet have to put full disk encryption and anti virus software on all our servers...

All of our servers are on aws ec2 / eks. The instances we do control aren't big enough for anti virus to be running...

God help me now

I think it's time to make a devrant bot automatically downvoting spam posts and spin it as 2 instances. Any takers? :)

fight automatism with automatism

robot fights of 2024 😁

Ok, I'm not saying there's a causal relationship here... I'm just going to say that the morning the VSCode Python extension is publicly moved in to the Microsoft product line, it starts devouring my resources by spawning a million instances of python.exe on startup. Computer unresponsive in minutes.

Again, I'm not *saying* there's a causal relationship... but I do find the timing somewhat suspicious.

I just witnessed Microsoft trolling preview setup.
Let me set the scene for you. I was in Visual Studio and saw the notifications and I had a minute so I decided to check them and saw there were updates, this one being one of them. I went to update and first it asked me to close all instances of VS. Fair enough, I close VS and continue. Instead of taking a minute at most to install it took ~10 minutes which is insane, but fine, I stopped my work for it... And then I'm greeted by this gem. Restart your computer for freaking .NET core and trolling.. I'm sorry, tooling... Preview... What the actual fuck Microsoft?

Are airwaves cast by WiFi and cell towers dangerous. Please link a credible source for it. During lunch my father brought up the fact that a actress sued the Indian government asking them to announce of 5g is dangerous or not. I said that it is not dangerous since we get higher amounts of radiation at us every day so 5g should not be anything dangerous for us. I should have said that it is non ionising radiation though. He also brought up that fact that there have been numerous instances of misleading advertising saying that what we use at our home is bad like saying ghee causes cholesterol which is bad and then a few years later saying that ghee is actually good. He just believes that companies could be doing false advertising saying that 5g is good when it actually is not. Can't blame him since he has seen multiple instances of false advertising.

Digging up on Google landed me on a nytimes article which basically said radiation 5g airwaves not effect us since our skin reflects that off and the small amount that does not get reflected heats up our skin to a negligible amount

I believe that I have found the worst feeling in the world.

Not when a push to production on Friday fails. But when a few of your teammates don't want to do JACK FUCKING SHIT. The worst ones are where they think you fabricated projected expenses for raspberry pies, and thus believe that you are apart of some communist conspiracy.

They also believe that cheap AWS ec2 instances are crappy for teaching some basic fucking command line and git to high schoolers!!

I feel like a need a brick handy at all times just to chuck it at a wall.

As I started learning React, I found the allure of declarative style of programming appealing. I try to avoid maintaining multiple state variables for data that can be derived from the base state itself that's stored in the redux store. It works wonders when I have to change something; as I just need to make changes to one function in the utils folder and that change is implemented across the whole app, rather than change the instances everywhere as was the case when I initially started working on this project after the previous dev left.

But I see myself redefining a lot of computed values everywhere, and if I just try to define them in the root component, I'll end up with a huge list of props being passed to a couple of components. Shifting it to the utils folder helps a bit, but then I find myself defining even the simplest of array filtering methods to the utils folder.

Is this need to define computed values everywhere a trade-off that you need to accept when you write declarative code, or is there a workaround/solution I am missing? As of now, the code-base is much better than how it used to be when they had a literal Java dev work on React with their knowledge of Java patterns being used in a framework that is the polar opposite of OOP, but I still feel like there's room for improvement in this duplication of computed values.

Reason #69 why I'm considering nuking windows on my main pc.

I had to print something... (I know, why would I want a document to exist in the physical world?)
1. The pc couldn't see the printer, that was connected via USB... Replugging the cable fixed it... How?
2. I had to print images, so I had pre-opened the 9 files. After printing 4 images windows decided to update the imageviewer, closing all the instances and not open them again... Wtf?

So that's how my evening was fucked, how was yours?

I jumped on this NodeJS codebase to quickly implement an additional method in the custom logger. How hard could it be, right?

I implemented the method alright. But I can't find where to use it... There are like 10 different logger instances used in this tiny app and in one place logger is even used as a vessel (holder object) for the client's JWT token (to access it from the interactor).

oh, and it's a javascript app (somehow I assumed that node apps are typescript.. silly me!)

What the fØ©ĸ spaghetty-fest is this!?!?!

C++: the Static Initialisation Order Fiasco. If you have two static instances in separate translation units, there is no way to guarantee their initialisation order, you're at the mercy of the compiler/linker. If one of the instance constructors depends on the other already being initialised, you have a 50% random chance of your program blowing up. The same ordering problem applies to global destruction at program termination time.
