Its Friday, you all know what that means! ... Its results day for practiseSafeHex's most incompetent co-worker!!!

*audience: wwwwwwooooooooo!!!!*

We've had a bewildering array of candidates, lets remind ourselves:

- a psychopath that genuinely scared me a little
- a CEO I would take pleasure seeing in pain
- a pothead who mistook me for his drug dealer
- an unbelievable idiot
- an arrogant idiot obsessed with strings

Tough competition, but there can be only one ... *drum roll* ... the winner is ... none of them!

*audience: GASP!*
*audience member: what?*
*audience member: no way!*
*audience member: your fucking kidding me!*

Sir calm down! this is a day time show, no need for that ... let me explain, there is a winner ... but we've kept him till last and for a good reason

*audience: ooooohhhhh*

You see our final contestant and ultimate winner of this series is our good old friend "C", taking the letters of each of our previous contestants, that spells TRAGIC which is the only word to explain C.

*audience: laughs*

Oh I assure you its no laughing matter. C was with us for 6 whole months ... 6 excruciatingly painful months.

Backstory:

We needed someone with frontend, backend and experience with IoT devices, or raspberry PI's. We didn't think we'd get it all, but in walked an interviewee with web development experience, a tiny bit of Angular and his masters project was building a robot device that would change LED's depending on your facial expressions. PERFECT!!!

... oh to have a time machine

Working with C:

- He never actually did the tutorials I first set him on for Node.js and Angular 2+ because they were "too boring". I didn't find this out until some time later.

- The first project I had him work on was a small dashboard and backend, but he decided to use Angular 1 and a different database than what we were using because "for me, these are easier".

- He called that project done without testing / deploying it in the cloud, despite that being part of the ticket, because he didn't know how. Rather than tell or ask anyone ... he just didn't do it and moved on.

- As part of his first tech review I had to explain to him why he should be using if / else, rather than just if's.

- Despite his past experience building server applications and dashboards (4 years!), he never heard of a websocket, and it took a considerable amount of time to explain.

- When he used a node module to open a server socket, he sat staring at me like a deer caught in headlights completely unaware of how to use / test it was working. I again had to explain it and ultimately test it for him with a command line client.

- He didn't understand the need to leave logging inside an application to report errors. Because he used to ... I shit you not ... drive to his customers, plug into their server and debug their application using a debugger.

... props for using a debugger, but fuck me.

- Once, after an entire 2 days of tapping me on the shoulder every 15 mins for questions / issues, I had to stop and ask:

Me: "Have you googled it?"
C: "... eh, no"
Me: "can I ask why?"
C: "well, for me, I only google for something I don't know"
Me: "... well do you know what this error message means?"
C: "ah good point, i'll try this time"

... maybe he was A's stoner buddy?

- He burned through our free cloud usage allowance for a month, after 1 day, meaning he couldn't test anything else under his account. He left an application running, broadcasting a lot of data. Turns out the on / off button on the dashboard only worked for "on". He had been killing his terminal locally and didn't know how to "ctrl + c a cloud app" ... so left it running. His intention was to restart the app every time you are done using it ... but forgot.

- His issue with the previous one ... not any of his countless mistakes, not the lack of even trying to make the button work, no, no, not for C. C's issue is the cloud is "shit" for giving us such little allowances. (for the record in a month I had never used more than 5%).

- I had to explain environment variables and why they are necessary for passwords and tokens etc. He didn't know it wasn't ok to commit these into GitHub.

- At his project meetups with partners I had to repeatedly ask him to stop googling gifs and pay attention to the talks.

- He complained that we don't have 3 hour lunch breaks like his last place.

- He once copied and pasted the same function 450 times into a file as a load test ... are loops too mainstream nowadays?

You see C is our winner, because after 6 painful months (companies internal process / requirements) he actually achieved nothing. I really mean that, nothing. Every thing was so broken, so insecure / wide open, built without any kind of common sense or standards I had to delete it all and start again ... it took me 2 weeks.

I hope you've all enjoyed this series and will join me in praying for the return of my sanity ... I do miss it a lot.

Yours truly,
practiseSafeHex

Long rant ahead, but it's worth it.

I used to work with a professor (let's call him Dr. X) and developed a backend + acted as sysadmin for our team's research project. Two semesters ago, they wanted to revamp the front end + do some data visualization, so a girl (let's call her W) joined the team and did all that. We wanted to merge the two sites and host on azure, but due to issues and impeding conferences that require our data to be online, we kept postponing. I graduate this semester and haven't worked with the team for a while, so they have a new guy in charge of the azure server (let's call him H), and yesterday my professor sends me (let's call me M), H and W an email telling us to coordinate to have the merge up on azure in 2-3 days, max. The following convo was what I had with H:

M: Hi, if you just give me access to azure I'll be able to set everything up myself, also I'll need a db set up, and just send me the connection string.
H: Hi, we won't have dbs because that is extra costs involved since we don't have dynamic content. Also I can't give you access, instead push everything on git and set up the site on a test azure server and I will take it from there.
M: There is proprietary data on the site...
H: Oh really? I don't know what's on it.
<and yet he knows we have no dynamic data>
M: Fine, I'll load the data some other way, but I have access to all the data anyway, just talk to Dr. X and you'll see you can give me access. Delete my access after if you want.
H: No, just do what I said: git then upload to test azure account.

Fine, he's a complete tool, but I like Dr. X, so I message W and tell her we have to merge, she tells me that it's not that easy to set it up on github as she's using wordpress. She sends me instructions on what to do, and, lo and behold, there's a db in her solution. Ok, I go back to talking to H:

M: W is using a db. Talk to her so we can figure out whether we need a database or not.
H: We can't use a database because we want to decrease costs.
M: Yes I know that, so talk to her because that probably means she has to re-do some stuff, which might take some time. Also there might be dynamic content in what she's doing.
H: This is your project, you talk to her.
<I'm starting to get mad right now>
M: I don't know what they had her do apart from how it interfaces with what I've done.
H: We still can't have databases.
M: Listen, I don't do wordpress, and I'm not gonna mess with it, you talk to her
H: I won't do any development
<So you won't do any dev, but you won't give me access to do it either?>
M: Man, the bottleneck isn't the merging right now, it's the fact that W needs a db
H: I know, so talk to her
M: THE RESTRICTION TO NOT HAVE DATABASES IS NOT MINE, IT'S YOURS, YOU TALK TO HER. I can't evaluate whether it's a reasonable enough reason or not since I don't know the requirements or what they're willing to spend.
H: It's your project.
M: Then give me fucking access to azure and I'll handle it, you know you'll have to set up wordpress again regardless whether we set it up the first time.
H: Man just do your job.

At this point I lost it. WHAT A FUCKING TOOL. He doesn't wanna do dev work, wants me to go through the trouble of setting up on a test subscription first, and doesn't want to give me access to azure. What's more, he did shit all and doesn't want to anything else. Well fuck you. I googled him, to see if he's anyone important, if he's done anything notable which is why he's being so God damn condescending. MY INTERNSHIP ALONE ECLIPSES HIS ENTIRE CV. Then what the fuck?

There's also this that happened sometime during our talk:

M: You'll have to take to Dr. Y so he'll change the DNS to point to the azure subscription instead of my server.
H: Yea don't worry, too early for that.
M: DNS propagation takes 24 hours...
H: Yea don't worry.

DNS propagation allows the entire web to know that your website is hosted on a different server so it can change where it's pointing to. We have to do this in 2-3 days. Why do work in parallel? Nah let's wait.

I went over his head and talked to the professor directly, and despite wanting to tell him that he was both drunk and high the day he hired that guy, I kept it professional. He hasn't replied yet, but this fucker's pompous attitude is just too much for me alone, so I had to share.

PS: I named his contact as Annoying Prick 4 minutes into our chat. Gonna rename him cz that seems tooooooo soft a name right now.

Oh, man, I just realized I haven't ranted one of my best stories on here!

So, here goes!

A few years back the company I work for was contacted by an older client regarding a new project.

The guy was now pitching to build the website for the Parliament of another country (not gonna name it, NDAs and stuff), and was planning on outsourcing the development, as he had no team and he was only aiming on taking care of the client service/project management side of the project.

Out of principle (and also to preserve our mental integrity), we have purposely avoided working with government bodies of any kind, in any country, but he was a friend of our CEO and pleaded until we singed on board.

Now, the project itself was way bigger than we expected, as the wanted more of an internal CRM, centralized document archive, event management, internal planning, multiple interfaced, role based access restricted monster of an administration interface, complete with regular user website, also packed with all kind of features, dashboards and so on.

Long story short, a lot bigger than what we were expecting based on the initial brief.

The development period was hell. New features were coming in on a weekly basis. Already implemented functionality was constantly being changed or redefined. No requests we ever made about clarifications and/or materials or information were ever answered on time.

They also somehow bullied the guy that brought us the project into also including the data migration from the old website into the new one we were building and we somehow ended up having to extract meaningful, formatted, sanitized content parsing static HTML files and connecting them to download-able files (almost every page in the old website had files available to download) we needed to also include in a sane way.

Now, don't think the files were simple URL paths we can trace to a folder/file path, oh no!!! The links were some form of hash combination that had to be exploded and tested against some king of database relationship tables that only had hashed indexes relating to other tables, that also only had hashed indexes relating to some other tables that kept a database of the website pages HTML file naming. So what we had to do is identify the files based on a combination of hashed indexes and re-hashed HTML file names that in the end would give us a filename for a real file that we had to then search for inside a list of over 20 folders not related to one another.

So we did this. Created a script that processed the hell out of over 10000 HTML files, database entries and files and re-indexed and re-named all this shit into a meaningful database of sane data and well organized files.

So, with this we were nearing the finish line for the project, which by now exceeded the estimated time by over to times.

We test everything, retest it all again for good measure, pack everything up for deployment, simulate on a staging environment, give the final client access to the staging version, get them to accept that all requirements are met, finish writing the documentation for the codebase, write detailed deployment procedure, include some automation and testing tools also for good measure, recommend production setup, hardware specs, software versions, server side optimization like caching, load balancing and all that we could think would ever be useful, all with more documentation and instructions.

As the project was built on PHP/MySQL (as requested), we recommended a Linux environment for production. Oh, I forgot to tell you that over the development period they kept asking us to also include steps for Windows procedures along with our regular documentation. Was a bit strange, but we added it in there just so we can finish and close the damn project.

So, we send them all the above and go get drunk as fuck in celebration of getting rid of them once and for all...

Next day: hung over, I get to the office, open my laptop and see on new email. I only had the one new mail, so I open it to see what it's about.

Lo and behold! The fuckers over in the other country that called themselves "IT guys", and were the ones making all the changes and additions to our requirements, were not capable enough to follow step by step instructions in order to deploy the project on their servers!!!

[Continues in the comments]

I absolutely HATE "web developers" who call you in to fix their FooBar'd mess, yet can't stop themselves from dictating what you should and shouldn't do, especially when they have no idea what they're doing.

So I get called in to a job improving the performance of a Magento site (and let's just say I have no love for Magento for a number of reasons) because this "developer" enabled Redis and expected everything to be lightning fast. Maybe he thought "Redis" was the name of a magical sorcerer living in the server. A master conjurer capable of weaving mystical time-altering spells to inexplicably improve the performance. Who knows?

This guy claims he spent "months" trying to figure out why the website couldn't load faster than 7 seconds at best, and his employer is demanding a resolution so he stops losing conversions. I usually try to avoid Magento because of all the headaches that come with it, but I figured "sure, why not?" I mean, he built the website less than a year ago, so how bad can it really be? Well...let's see how fast you all can facepalm:

1.) The website was built brand new on Magento 1.9.2.4...what? I mean, if this were built a few years back, that would be a different story, but building a fresh Magento website in 2017 in 1.x? I asked him why he did that...his answer absolutely floored me: "because PHP 5.5 was the best choice at the time for speed and performance..." What?!

2.) The ONLY optimization done on the website was Redis cache being enabled. No merged CSS/JS, no use of a CDN, no image optimization, no gzip, no expires rules. Just Redis...

3.) Now to say the website was poorly coded was an understatement. This wasn't the worst coding I've seen, but it was far from acceptable. There was no organization whatsoever. Templates and skin assets are being called from across 12 different locations on the server, making tracking down and finding a snippet to fix downright annoying.

But not only that, the home page itself had 83 custom database queries to load the products on the page. He said this was so he could load products from several different categories and custom tables to show on the page. I asked him why he didn't just call a few join queries, and he had no idea what I was talking about.

4.) Almost every image on the website was a .PNG file, 2000x2000 px and lossless. The home page alone was 22MB just from images.

There were several other issues, but those 4 should be enough to paint a good picture. The client wanted this all done in a week for less than $500. We laughed. But we agreed on the price only because of a long relationship and because they have some referrals they got us in the door with. But we told them it would get done on our time, not theirs. So I copied the website to our server as a test bed and got to work.

After numerous hours of bug fixes, recoding queries, disabling Redis and opting for higher innodb cache (more on that later), image optimization, js/css/html combining, render-unblocking and minification, lazyloading images tweaking Magento to work with PHP7, installing OpCache and setting up basic htaccess optimizations, we smash the loading time down to 1.2 seconds total, and most of that time was for external JavaScript plugins deemed "necessary". Time to First Byte went from a staggering 2.2 seconds to about 45ms. Needless to say, we kicked its ass.

So I show their developer the changes and he's stunned. He says he'll tell the hosting provider create a new server set up to migrate the optimized site over and cut over to, because taking the live website down for maintenance for even an hour or two in the middle of the night is "unacceptable".

So trying to be cool about it, I tell him I'd be happy to configure the server to the exact specifications needed. He says "we can't do that". I look at him confused. "What do you mean we 'can't'?" He tells me that even though this is a dedicated server, the provider doesn't allow any access other than a jailed shell account and cPanel access. What?! This is a company averaging 3 million+ per year in revenue. Why don't they have an IT manager overseeing everything? Apparently for them, they're too cheap for that, so they went with a "managed dedicated server", "managed" apparently meaning "you only get to use it like a shared host".

So after countless phone calls arguing with the hosting provider, they agree to make our changes. Then the client's developer starts getting nasty out of nowhere. He says my optimizations are not acceptable because I'm not using Redis cache, and now the client is threatening to walk away without paying us.

So I guess the overall message from this rant is not so much about the situation, but the developer and countless others like him that are clueless, but try to speak from a position of authority.

If we as developers don't stop challenging each other in a measuring contest and learn to let go when we need help, we can get a lot more done and prevent losing clients. </rant>

"Ok, the site looks fine. Now let's move the style tag into it's own file."

*makes css file*

"WHY DOES IT HARDLY EVER LOAD!?!?, I checked the syntax trice"

*Spends 20 min. Asking friends for help, but none of them knows a reason*

"Time to ask the teacher, I guess"

*Teacher comes over, but has no clue either*

Teacher: "Give me the files, let's test it on my laptop"

*Css doesn't load there either*

*Teachers pair programming and trying some serious debugging technics. No progress*

*I decided to look at the sourcecode while refreshing the site*

1. Refresh: Css is loaded properly
2. Refresh: Css is gone, and source turned into various asian symbols.

Looks at the (default) file encoding: UCS-2
WTF NOTEPAD++, I SPEND 2 HOURS OF MY LIFE BECAUSE YOU DECIDED THIS WAS A PROPER ENCODING!

Web programming seems fun.

Write a small js function using setInterval to fire a request every second ... then copy paste the code 450 times (literally, not an exaggeration) into a massive file to create a load test script.

This load test script also had no means to gather metrics or test response times or anything useful. It was literally a “did the server crash” test.

I've had my share of incompetent coworkers. In order of appearance:

1. A full stack dev. This one guy never, and I mean NEVER uses relationships in their tables. No indexing, no keys, nada. Couple of months later he was baffled why his page took ten seconds to load.

2. The same dev as (1). Requirement was to create some sort of "theme" feature for a web app. Hacked it by putting !important all over the place.

3. The same dev again. He creates several functions that if the data exists returns a view, and if it doesn't, "echo '0'". No, not return 0 or return false or anything, but fucking echo. This was PHP. If posted a rant about this a few months ago.

4. Same dev, has no idea what clean code is. No, not just reusable functions, he doesn't even get indenting right. Some functions have 4 spaces, some 2 tabs, some 6 tabs! And this is inside the same function. God wait until he tries Python...

5. Same dev now suggests that he become the PM. GM approves (very small company). Assigns me to travel to a client since they needed "technical assistance about the API". Was actually there to lead a UAT session.

Intermezzo, that guy went from fullstack dev to PM to sales (yes, one who calls clients to offer products) to business development, to product analyst in the span of two years.

After a year and a half there, I quit.

6. New company, a "QA engineer" who also assumes the role as the product owner. Does absolutely no tests other than "functional tests" in which he NEVER produces any form of documentation. Not even a set of test cases. He goes by "intuition".

7. Same guy as (6), hands me requirements for a feature. By "hands me" I mean he did that verbally. No spec documents, no slack chat, no Trello card. I ended up writing it as a card in Trello. Fast forward to the due date, he flips out because that wasn't what he wanted. Showed him the card. He walked away, without thinking of a solution how this mess should be handled.

Despite all this, I really don't want him (6&7) to leave the company. The devs get really stressed out at this job and he does make a really good person to laugh with/at.

My boss caught me out the other day. He asked which browser do we test on. In our documentation it's ff chrome and ie10. In reality it's not ie.

I opened ie for the first time in a long time the other day to find a crap load of bugs. Including the attached.

So my ethernet randomly stopped working on Arch.

At first I thought it had to do with a conflict between it and my tethered phone, so I tried removing all my connections. Still wasn't working.

Next I tried to test the driver itself and make sure it loaded on boot. It loaded, but was disconnected.

Next I decided "fuck it, I know I was just using the internet on Windows, but I'll check the ethernet cable is still plugged in anyway". It was, and it was returning the right MAC address, but still no connection.

So I try debugging the driver further. Everything seemed fine, except it would time out trying to establish a dhcp connection.

Finally I figured, maybe Microsoft tried to troll me and lock out the ethernet waking on boot. So I restart my computer, load into windows and check my ethernet driver, it seems fine. I go to disable the shutdown of the card on OS shutdown. Turns out this driver no longer has that capability.

Wait a minute!? Windows is also having connection issues!?

I look to my left.

Fuck my life...

My router was off... I must of kicked the powerboard under my desk..........

So, some time ago, I was working for a complete puckered anus of a cosmetics company on their ecommerce product. Won't name names, but they're shitty and known for MLM. If you're clever, go you ;)

Anyways, over the course of years they brought in a competent firm to implement their service layer. I'd even worked with them in the past and it was designed to handle a frankly ridiculous-scale load. After they got the 1.0 released, the manager was replaced with some absolutely talentless, chauvinist cuntrag from a phone company that is well known for having 99% indian devs and not being able to heard now. He of course brought in his number two, worked on making life miserable and running everyone on the team off; inside of a year the entire team was ex-said-phone-company.

Watching the decay of this product was a sheer joy. They cratered the database numerous times during peak-load periods, caused $20M in redis-cluster cost overrun, ended up submitting hundreds of erroneous and duplicate orders, and mailed almost $40K worth of product to a random guy in outer mongolia who is , we can only hope, now enjoying his new life as an instagram influencer. They even terminally broke the automatic metadata, and hired THIRTY PEOPLE to sit there and do nothing but edit swagger. And it was still both wrong and unusable.

Over the course of two years, I ended up rewriting large portions of their infra surrounding the centralized service cancer to do things like, "implement security," as well as cut memory usage and runtimes down by quite literally 100x in the worst cases.

It was during this time I discovered a rather critical flaw. This is the story of what, how and how can you fucking even be that stupid. The issue relates to users and their reports and their ability to order.

I first found this issue looking at some erroneous data for a low value order and went, "There's no fucking way, they're fucking stupid, but this is borderline criminal." It was easy to miss, but someone in a top down reporting chain had submitted an order for someone else in a different org. Shouldn't be possible, but here was that order staring me in the face.

So I set to work seeing if we'd pwned ourselves as an org. I spend a few hours poring over logs from the log service and dynatrace trying to recreate what happened. I first tested to see if I could get a user, not something that was usually done because auth identity was pervasive. I discover the users are INCREMENTAL int values they used for ids in the database when requesting from the API, so naturally I have a full list of users and their title and relative position, as well as reports and descendants in about 10 minutes.

I try the happy path of setting values for random, known payment methods and org structures similar to the impossible order, and submitting as a normal user, no dice. Several more tries and I'm confident this isn't the vector.

Exhausting that option, I look at the protocol for a type of order in the system that allowed higher level people to impersonate people below them and use their own payment info for descendant report orders. I see that all of the data for this transaction is stored in a cookie. Few tests later, I discover the UI has no forgery checks, hashing, etc, and just fucking trusts whatever is present in that cookie.

An hour of tweaking later, I'm impersonating a director as a bottom rung employee. Score. So I fill a cart with a bunch of test items and proceed to checkout. There, in all its glory are the director's payment options. I select one and am presented with:

"please reenter card number to validate."

Bupkiss. Dead end.

OR SO YOU WOULD THINK.

One unimportant detail I noticed during my log investigations that the shit slinging GUI monkeys who butchered the system didn't was, on a failed attempt to submit payment in the DB, the logs were filled with messages like:

"Failed to submit order for [userid] with credit card id [id], number [FULL CREDIT CARD NUMBER]"

One submit click later and the user's credit card number drops into lnav like a gatcha prize. I dutifully rerun the checkout and got an email send notification in the logs for successful transfer to fulfillment. Order placed. Some continued experimentation later and the truth is evident:

With an authenticated user or any privilege, you could place any order, as anyone, using anyon's payment methods and have it sent anywhere.

So naturally, I pack the crucifixion-worthy body of evidence up and walk it into the IT director's office. I show him the defect, and he turns sheet fucking white. He knows there's no recovering from it, and there's no way his shitstick service team can handle fixing it. Somewhere in his tiny little grinchly manager's heart he knew they'd caused it, and he was to blame for being a shit captain to the SS Failboat. He replies quietly, "You will never speak of this to anyone, fix this discretely." Straight up hitler's bunker meme rage.

We're getting a lot of traffic, we need this bitch to scale! *auto-scale and load balance all the things*

Account creation begins breaking at random, some people receiving the "Your IP address doesn't match" error. Look at login history table, what the shit... All recent logins coming from internal IP addressohfuckmylife need to look at X-Forwarded-For header for actual IP behind load balancer.

IP address matching feature stays. I am sad, drink away sadness.

I have to make this a separate rant.
It's been going on for months, and I don't have alternatives.

This.

This is what I pay 35€ per month for. Every evening it's like this. Usually it can't even load the speed test. Right now it can't even load the upload meter.

A big FUCK YOU to Vodafone in Berlin. Giant ass FUCK YOU, for just promises and appalling service.

I have been creating mods for Skyrim and Fallout for a few years now. One day another modder wanted to make his own game using Unreal Engine 4. I wanted to learn UE4 anyway and the other members have made many mods before, so I joined in.

Well, it turned out I was the only one with a professional programming background (this is where I should have run). The others were all modders who somehow got their shit working. "It works, so it's good enough right?" On top of that UE4 has a visual scripting system called Blueprint. Instead of writing code you connect function blocks with execution lines. Needles to say that spaghetti code gets a whole new meening.

There was no issue board, no concept, no plan what the game should look like. Everyone was just doing whatever he wants and adding tons of gameplay mechanics. Gameplay mechanics that I had to redo because they where not reusable, not maintainable or/and poorly performing.

Coming from a modding background, they wanted to make the game moddable. This was the #1 priority. The game can only load "cooked" assets when it got packaged. So to make modding possible, we needed to include the unpacked project files in the download. This made the download size grow to 20+ GB. 20 GB for a fucking sidescroller. Now, 1 year after release we have one mod online: Our own test mod.

Well we "finished" the game eventually and it got released on Steam. A 20 GB sidescroller for $6.99. It's more like a $2.99 game in my opinion. But instead of lowering the price they increased it to $9.99, because we have spent so much time creating the game. Since that we selled less than 5 more copies. And now they want to make it work on mobile. Guess who will definetly NOT help them.

I have spent ~6 month of my freetime for this project, my rev share is < 100€ and they got me a lot of headaches with all their dumb decisions. Lesson learned. But hey, I am pretty good with UE4 now.

I feel like the web frontend landscape has gone to hell...

It used to be a priority to develop lean front end applications that load fast and work the same on most devices. If resources are required you try to share them. I have always liked the way this was solved using CDN.

Proper workflow: include some small libs you might need, script your interactions, test site, deliver.

And now our friends of the Javascript community have discovered the nuclear science called npm... It started off as this great benefit allowing frontenders to complete entire projects in the language they know and love but I feel like it has grown into an abomination that produces bulky applications with more boilerplate configuration than actual active code...

Surely I can't be the only one who is completely fed up with the direction this is going? Is anyone else looking for a lean way of developing javascript again using only a couple of small libs instead of those monstrous frameworks.

I have even considered to develop a library that makes it easy to develop with CDN (and dependencies) in mind but I don't even know if it will be worth it as more and more people tend to move away from it.

I'm sad

I fucking hate my boss so much

He looks down on me like I’m some idiot who doesn’t know his shit.
The other day he was trying to explain OAuth2.0 to me in the most dumbed down way ever, even after telling him I do already know how OAuth 2.0 works. He just said “oh well just making sure” and continued explaining it to me the exact same way. Felt shitty having something explained to you which you already know in such a way in front of all of your coworkers

Whenever I give my thoughts on something he answers with an argument that’s essentially true but pretty stupid:

B: “We don’t need to bundle our JS files” (see my other rant)
M: “Our load time is around 15 seconds though and it takes forever to update our script tags”
B: “Yes but it’s only 15 seconds once and the tags are already there so it’s fine”

How do you reply to something like that??

On top of that, his code is absolutely awful, always looks hacked together, lacks documentation and i don’t think he has written a unit test in his life

I don’t even like frontend, was told I would mostly do backend and it seems like all I’m doing recently is write fucking javascript because even if I wanted to write backend code, it’s nearly impossible to write clean code in this pile of horseshit codebase

AWS DBAs: your application is wrong.
We: Ora didn't complain about that...

AWS DBAs: umm.. Err.. Then your load test is wrong
We: ora wasn't complaining about that either...

AWS DBAs: errr.. Ummm.. Oh, I've got it! Your queries aren't optimized!
We: we cannot change queried - they are hardcoded by our framework's vendor

AWS DBAs: well there you go! Your queries aren't optimized! It's your fault, not aurora's

yyeeahhhh... Riight...

From my xp, aws support and aws engineers ALWAYS try to put the blame on a client. Always. Even when they're obviously wrong.

html email test sent to client:
Client: Great but I can't see any images.
Me: You may have "load images" disabled in your email client/preferences.
Client: (a few hours later) can you make it so that the images appear even if "load images" is disabled?

In my web dev languages class today I went to try the feature to test the site through VS. Literally every browser BUT Edge would load... Even a Microsoft product knows that Edge is shit.

Rant!

Been working on 'MVP' features of a new product for the past 14 months. Customer has no f**king clue on how to design for performance. An uncomfortable amount of faith was placed on the ORM (ORMs are not bad as long as you know what you are doing) and the magic that the current framework provides. (Again, magic is good so long as you understand what happens behind the smoke and mirrors - but f**k all that... coz hey, productivity, right?). Customer was so focussed on features that no one ever thought of giving any attention to subtler things like 'hey, my transaction is doing a gazillion joins across trizillion tables while making a million calls to the db - maybe I should put more f**king thought into my design.' We foresaw performance and concurrency issues and raised them way ahead of the release. How did the customer respond? By hiring a performance tester. Fair enough - but what did that translate into? Nothing. Nada. Zilch. Hiring a perf tester doesn't automagically fix issues. The perf tester did not have a stable environment, a stable build or anything that is required to do a test with meaningful results. As the release date approached, the customer launched a pilot and things started failing spectacularly with the system not able to support more than 15 concurrent users. WTF! (My 'I told you so' moment) Emails started flying in all directions and the hunt for the scapegoat was on (I'm a sucker for CYA so I was covered). People started pointing in all directions but no one bothered to take a step back and understand what was causing the issues. Numero uno reason for transaction failure was deadlocks. We were using a proprietary DB with kickass tooling. No one bothered to use the tooling to understand what was the resource in contention let alone how to fix the contention. Absolute panic - its like they just froze. Debugging shit and doing the same thing again and again just so that management knew they were upto something. Most of the indexes had a fragmentation of 99.8% - I shit you not. Anywho, we now have a 'war room' where the perf tester needs to script the entire project by tonight and come up with some numbers that will amount to nothing while we stay up and keep profiling the shit out of the application under load.

Lessons learnt - When you foresee a problem make a LOT of noise to get people to act upon it and not wait till it comes back and bites you in the ass. Better yet, try not to get into a team where people can't understand the implications of shitty design choices. War room my ass!

Today I had a programming exam

We had to read a request, write uml, use case etc...

I think "it's going to be easy!"

Than I remember that for some unholy reason we use java7

Than I remember that the keyword to automatically add getters and setters was added in java10

Had to write getters and setters by hand, on a piece of paper, for 5 classes...

I hate my university, we are Information Engineering that is the closest thing we have to Software Engineering in my city and we still do our programming exams on paper, that doesn't test your ability to program, but your ability to learn a load of information by memory

Fucking incompetence

Senior level developer with 15 years of software development experience ...

ends up writing brute force search on a sorted data - when questioned he's like yeah well dataset is not that large so performance degradation will be marginal

He literally evades any particularly toil heavy task like fixing the unit test cases , or managing the builder node versions to latest ( python 2 to 3 ) because it's beneath him and would rather work on something flashy like microservice microfrontend etc. -- which he cannot implement anyway

Or will pick up something very straightforward like adding a if condition to a particular method just to stay relevant

And the management doesn't really care who does what so he ends up getting away with this

The junior guys end up taking up the butt load of crappy tasks which are beneath the senior guy

And sometimes those tasks are not really junioresque - so we end up missing deadlines and getting questioned as to why we are are not able to deliver.

Fuck this shit ... My cortisol shoots up whenever I think of him

I'm a contractor at a product company and today I had the pleasure of working with some jQuery.

A function needed to be called before another function, hard work right?

So I moved the call to the function 3 rows higher, checked it in, set the task as ready for test and started to look for other tasks.
Within a couple of minutes I get a direct message from another dev, let's call him Steve.
Steve wanted me to set the task to ready for code review instead of test, so I did just that and tried to move on.

Some minute or two later Steve contacts me again:
"It would be great if you'd move the comment so it'd be over the call to the function"

Well, I'm not one of those who likes comments... If you need a comment, it's probably not good/readable code. In some cases sure, it might be a complex block coming up.
Sorry, lost my train of thought.

I answered Steve : "Are you sure, I could just remove it instead?"

(for readability S will be Steve and M will be me)

S: Well, it's always good to have comments
M: In this case I think it will be alright.
S: But it's nice to see what the function is doing.
M: I'll do it if you really want me to.
S: It's better to have the comment than to not have it and needing it.
M: Okay then

The name of the function : LoadOrganizationTree()

And this is the comment :
//Load organization tree

MTP is utter garbage and belongs to the technological hall of shame.

MTP (media transfer protocol, or, more accurately, MOST TERRIBLE PROTOCOL) sometimes spontaneously stops responding, causing Windows Explorer to show its green placebo progress bar inside the file path bar which never reaches the end, and sometimes to whiningly show "(not responding)" with that white layer of mist fading in. Sometimes lists files' dates as 1970-01-01 (which is the Unix epoch), sometimes shows former names of folders prior to being renamed, even after refreshing. I refer to them as "ghost folders". As well known, large directories load extremely slowly in MTP. A directory listing with one thousand files could take well over a minute to load. On mass storage and FTP? Three seconds at most. Sometimes, new files are not even listed until rebooting the smartphone!

Arguably, MTP "has" no bugs. It IS a bug. There is so much more wrong with it that it does not even fit into one post. Therefore it has to be expanded into the comments.

When moving files within an MTP device, MTP does not directly move the selected files, but creates a copy and then deletes the source file, causing both needless wear on the mobile device' flash memory and the loss of files' original date and time attribute. Sometimes, the simple act of renaming a file causes Windows Explorer to stop responding until unplugging the MTP device. It actually once unfreezed after more than half an hour where I did something else in the meantime, but come on, who likes to wait that long? Thankfully, this has not happened to me on Linux file managers such as Nemo yet.

When moving files out using MTP, Windows Explorer does not move and delete each selected file individually, but only deletes the whole selection after finishing the transfer. This means that if the process crashes, no space has been freed on the MTP device (usually a smartphone), and one will have to carefully sort out a mess of duplicates. Linux file managers thankfully delete the source files individually.

Also, for each file transferred from an MTP device onto a mass storage device, Windows has the strange behaviour of briefly creating a file on the target device with the size of the entire selection. It does not actually write that amount of data for each file, since it couldn't do so in this short time, but the current file is listed with that size in Windows Explorer. You can test this by refreshing the target directory shortly after starting a file transfer of multiple selected files originating from an MTP device. For example, when copying or moving out 01.MP4 to 10.MP4, while 01.MP4 is being written, it is listed with the file size of all 01.MP4 to 10.MP4 combined, on the target device, and the file actually exists with that size on the file system for a brief moment. The same happens with each file of the selection. This means that the target device needs almost twice the free space as the selection of files on the source MTP device to be able to accept the incoming files, since the last file, 10.MP4 in this example, temporarily has the total size of 01.MP4 to 10.MP4. This strange behaviour has been on Windows since at least Windows 7, presumably since Microsoft implemented MTP, and has still not been changed. Perhaps the goal is to reserve space on the target device? However, it reserves far too much space.

When transfering from MTP to a UDF file system, sometimes it fails to transfer ZIP files, and only copies the first few bytes. 208 or 74 bytes in my testing.

When transfering several thousand files, Windows Explorer also sometimes decides to quit and restart in midst of the transfer. Also, I sometimes move files out by loading a part of the directory listing in Windows Explorer and then hitting "Esc" because it would take too long to load the entire directory listing. It actually once assigned the wrong file names, which I noticed since file naming conflicts would occur where the source and target files with the same names would have different sizes and time stamps. Both files were intact, but the target file had the name of a different file. You'd think they would figure something like this out after two decades, but no. On Linux, the MTP directory listing is only shown after it is loaded in entirety. However, if the directory has too many files, it fails with an "libmtp: couldn't get object handles" error without listing anything.

Sometimes, a folder appears empty until refreshing one more time. Sometimes, copying a folder out causes a blank folder to be copied to the target. This is why on MTP, only a selection of files and never folders should be moved out, due to the risk of the folder being deleted without everything having been transferred completely.

Dev: The server is completely down right now. Nobody can access the application, we need to divert some resources to horizontally scaling our app.

Manager: Hm, this was not in the schedule. I need to consult senior leadership on what to do about this. I don’t want to be held accountable for making a decision on this complex and highly nuanced situation.

Dev: No need, I have a solution. Just need a week to build/test/deploy the ability to horizontally scale.

Manager: But that will cause delays to new features.

Dev: New features don’t matter if the app can’t even load.

Manager: Ok you can implement your solution but it can’t take any time. I need those new features out.

Dev: ???????

So I have 1mb/s internet that cuts out every ~5 min - i had to wait for internet connection to load the speed test.

I am just outside London - internet speed should not be bad, i am not exactly in the middle of nowhere

Are devrant servers dying? Algo sorting doesn’t load more rants and recents sorting is kinda wonky.

I tried official devrant app on ios and joyrant with same results.

This is kind of a test if I can still rant or not.

Our project at work goes live in 3 weeks.

The code base has no automated tests, breaks very often, has never had any level of manual testing

will not be releasing with any form of enforced roles or permissions in our first release now due to no time to enforce, however there is a whole admin api where you can literally change anything in our database including roles.

We also have teams in various countries all working separately on the same solution using microservices with shared nuget packages and they aren't using them properly.

Our pull requests are so big - as much as, 75 file changes - in our fe app that I can't keep up with it and I honestly have no idea if it even works or not due to no automated tests and no time to manually test.

We have no testing team, or qa team of any sort.

Every request into the system has to hit a minimum of 3 different databases via 3 different microservices so 1 request = 4 requests with the load on the servers.

We don't use any file streams so everything is just shoved in the buffer on the server.

Most of the people working on the angular apps cba to learn angular, no one across 2 teams cba to learn git. We use git so they constantly face problems. The guy in charge has 0 experience in angular but makes me do things how he wants architecturally so half the patterns make no sense.

No one looks at the pull requests, they just click approve so they may as well push directly to master.

Unfinished work gets put in for pull request so we don't know if the app is in a release state since aall teams are working independently, but on the same code base.

I sat down and tested the app myself for an hour and found 25 fe only issues, and 5 breaking cross browser issues.

Most of our databases are not normalised. Most of our databases make no sense. 99% of our tables have no indexing since there is no expertise with free time to do it.

No one there understands css properly. Or javascript.

Our. Net core microservices all directly use ef in the controller actions so there is no shared code there.

Our customer facing fe app is not dry because no tests so it was decided it was better this way.

Management has no idea on code state, it seems team lead is lieing to them about things like having any level of tests.

Management hire devs that claim to be experts but then it turns out they have basically no knowledge of what they were hired to do, even don't know what json is or the framework or language they are hired for, but we just leave them to get on with it and again make prs too big to review.

Honestly I have no hope that this will go well now but I am morbidly curious to watch. I've never seen anything like the train wreck that we are about to get experience.

Team: * hands over release to QA
QA: Release broken. It doesn't load any entries from the test system.
Me: Not possible. It works perfectly fine in our environment and we haven't touched that logic in weeks.

A couple of days later...
QA: It seems that we accidentally deleted all the entries from our environment. We'll apply a backup.

Team, clients, air wasted to keep these people alive:

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 <...>

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...

The reason for half the web-dev world sufferings is that Microsoft won't stop choking their users with explorer or edge, and half of the client are too dumb or lazy to download a different browser to test stuff. Fuck this shit man! Nothing works the way it should on this bitch.

Everytime my manager says- It should work perfectly on IE because client doesn't have any other browser, I curse IE for exisiting. If you can't improve it, just remove it you freakin' sadists. It'll not be an embarrassment to load something better on your OS. If anything, it'll get people to like you maybe. Like you for accepting your fuckery and making a decision in favor of the web dev world and innocent windows users, who only use your explorer to download other browser asap. For just that one time and for all your arrogance, you're making the whole world suffer.

ME: *runs a load test for the umpteenth time*

RDS DB: *is slow af: HI contentions*

ME: "dear AWS support, I see the RDS has troubles writing to disk as THIS db exhibits 10x higher W latencies than THAT OTHER db we have. Both are identical, apps are identical."

AWS: "Hello, I hope you have a good day. After the investigation that took us almost 2 weeks, we can confirm that there are 10x higher IO latencies to disks: [CloudWatch link]. We also see a high load average during your tests.

We recommend investigating the high load average and tuning your queries along with the database.

I hope this helps, good day."

ME: *are you seriously calling this PREMIUM support package....?*

I've finally got a monitor at work that works with Samsung Dex.
Positive things:
- new super cool monitor
- can remove windows now from the dual boot of the laptop since everything I needed it for can be now done on Dex.

Negative things:
- DevRant doesn't work with Dex. It just doesn't load properly. But maybe it will work through a browser. Need to test...

Q.13 - Which one of the following is used in DHCP process ?
A. Boot, Test, Load, Start
B. Discover, Host, Configure, Process
C. Discover, Offer, Request, Acknowledge
D. Syn, Syn/Ack, Ack
E. I'm the DHCP server now.

Due to coronovirus, my work asked everyone to login for 30mins (in a 2hr window) to test test max load/capacity...

1. how do you test max load if people can login at different times...

2. Isn't there software that can test that.... Isn't this load testing?

In This Rant: A mildly satisfying piece of mind story.

Using code to prove yourself right is a hell of a drug.

A few weeks ago I whipped up a tiny program that downloads configs from hardware we manage. Since the vendor's API documentation is hidden behind a pay wall, my method of extraction is different. It results in bigger files, but testing showed it to still be valid.

Enter today. Interns at work downloaded a config to load onto a spare machine and it won't work.

"TheCapeGreek, your configs don't work"

I was confused since I tested the files when I built it and it worked. I am also currently fleshing out that download utility's features so the fear that I've been wasting the past 2 weeks on improvements is looming.

Last 15 minutes of the day and nothing else to do so I figured I might as well whip up a string comparer. The smaller file's content is scattered in the big file so a direct diff won't work.

Code it all, quick hardcoded proof of concept code, bit it got the job done. I was right, my bigger file is still correct!

Turns out the issue was with the machine they were configuring. They found this out before I finished my test code, so I'm off the hook already, but it was good to have piece of mind haha!

How is coupling backend + frontend as a single nextjs app a good idea? What the fuck is this?

What if you have to create new replica sets of a backend because of high load pressure? What about load balancers?? What if i want my backend to be a microservice? How do i unit test the backend if its cluttered with frontend? WTF IS THIS

WHY DID NEXTJS THINK THIS IS A GOOD IDEA AND WHY DO SO MANY DEVS LOVE THIS IDEA AND GLORIFY NEXTJS?

Nextjs seems like the type of framework that was built by a frontend web developer who just refuses to learn backend technology at all costs.

---

its been a few hours and the concept of nextjs is bending my mind rn. I thought nextjs is just another frontend framework. A react killer. Only to find out its both a backend + frontend framework.

Cluttering backend stuff into frontend is gonna get messy no matter how much you try to modularize the code. Am i lost or am i right???

---

Scratching my head over nextjs. Looks like a great framework for small-mid project but definitely not large project. The more shit the project needs the more messy shit become. Angular has modularized all of this in separate folders -- components services guards interceptors (now new stuff coming called Signals) etc. All of it is separated in individual folders and kept frontend-only. Simple enough. No backend clutter

---

Can i even use nextjs strictly as a frontend framework while it uses my custom backend built in java spring boot? For example use nextjs /api/ folder to handle custom routes built outside of nextjs framework?

Am i insane here

Why can’t IE just die?!

I was sent home for almost 3 months due to the pandemic, when I came back on monday there was a major issue with page load speed on IE and some potential customer, had a test account and told us that the platform is taking forever too load and then came the hunt to fix what is asap, it was a very important customer that still uses IE

This happens last week, the only developer on the job last week, was 3 days trying to figure this out, no dice! then I come back on monday, then Im being reboarded and keep up to date what has been going on while away, then I am given that damn task on Wednesday and I’ve been tearing out my hair trying to fix this all week.

But today!

I fixed it!

The solution: npm update <package-name>

Great way to start up at work again *clap*

When devRant take a minute to load any page on your main optic fiber connection, and speed test says that everything is fine....😤
UNACCEPTABLE!!!!!
bah at least the 4G works properly 😧

Why use git, do it simple, send me your changes by email and I will merge it.
Why split split source code (js) into different files, use one so we will no have trouble about load order.
Use the same user account for github/gitlab/bitbucket/etc. So we will no worry to setup access permisions.
Use Dropbox/Drive for version control.
We will test the whole system until the end when all is finish.

Fuck me I'm pissed. This sprint, my tech lead has been away and a senior dev has been covering for him. We plan a load of work and distribute stories and we churn threw it quite well. However, my senior dev says let's not deploy until all the works done. I was like, how is it going to be tested? He was like well it will be fine because it's all one test. Bs. We now have 2 days left, tester is getting stressed because they don't know what to test or what's been finished. Scrum master is asking why all of it should be tested at the same time and I'm here like this is fucking dumb. Also the tester decided to start testing with the most complex piece of work, rather than prioritising.

Starting to wonder if I'm just the outsider or whether no one understands that granularity is better.

We take over development of a live customer facing system and PM agrees date for our first code deployment with client CIO
Me: The dev and staging environments don't have any test data currently as the old agency screwed it up
PM: Well you better load some
Me: There isn't any... It'll take 10 days to copy prod db due to hosting provider SLAs, leaving 1 week for SIT, UAT and performance testing (assuming they don't screw up)
PM: Well the date is set, 1 week will be enough for testing

My company insists on working in one production environment to save time and every time I try to convince them to set up a work flow with a dev and test environment, they tell me we don't have the time...

Even after I set one up anyway as I'm scared shitless to touch production. They tell me it's faster doing it all in one environment.

They launch an update. Site buggy as hell and doesn't load 90% of the content...

Sigh....

I need some opinions on Rx and MVVM. Its being done in iOS, but I think its fairly general programming question.

The small team I joined is using Rx (I've never used it before) and I'm trying to learn and catch up to them. Looking at the code, I think there are thousands of lines of over-engineered code that could be done so much simpler. From a non Rx point of view, I think we are following some bad practises, from an Rx point of view the guys are saying this is what Rx needs to be. I'm trying to discuss this with them, but they are shooting me down saying I just don't know enough about Rx. Maybe thats true, maybe I just don't get it, but they aren't exactly explaining it, just telling me i'm wrong and they are right. I need another set of eyes on this to see if it is just me.

One of the main points is that there are many places where network errors shouldn't complete the observable (i.e. can't call onError), I understand this concept. I read a response from the RxSwift maintainers that said the way to handle this was to wrap your response type in a class with a generic type (e.g. Result<T>) that contained a property to denote a success or error and maybe an error message. This way errors (such as incorrect password) won't cause it to complete, everything goes through onNext and users can retry / go again, makes sense.

The guys are saying that this breaks Rx principals and MVVM. Instead we need separate observables for every type of response. So we have viewModels that contain:

- isSuccessObservable
- isErrorObservable
- isLoadingObservable
- isRefreshingObservable
- etc. (some have close to 10 different observables)

To me this is overkill to have so many streams all frequently only ever delivering 1 or none messages. I would have aimed for 1 observable, that returns an object holding properties for each of these things, and sending several messages. Is that not what streams are suppose to do? Then the local code can use filters as part of the subscriptions. The major benefit of having 1 is that it becomes easier to make it generic and abstract away, which brings us to point 2.

Currently, due to each viewModel having different numbers of observables and methods of different names (but effectively doing the same thing) the guys create a new custom protocol (equivalent of a java interface) for each viewModel with its N observables. The viewModel creates local variables of PublishSubject, BehavorSubject, Driver etc. Then it implements the procotol / interface and casts all the local's back as observables. e.g.

protocol CarViewModelType {
isSuccessObservable: Observable<Car>
isErrorObservable: Observable<String>
isLoadingObservable: Observable<Void>
}

class CarViewModel {
isSuccessSubject: PublishSubject<Car>
isErrorSubject: PublishSubject<String>
isLoadingSubject: PublishSubject<Void>

// other stuff
}

extension CarViewModel: CarViewModelType {
isSuccessObservable {
return isSuccessSubject.asObservable()
}
isErrorObservable {
return isSuccessSubject.asObservable()
}
isLoadingObservable {
return isSuccessSubject.asObservable()
}
}

This has to be created by hand, for every viewModel, of which there is one for every screen and there is 40+ screens. This same structure is copy / pasted into every viewModel. As mentioned above I would like to make this all generic. Have a generic protocol for all viewModels to define 1 Observable, 1 local variable of generic type and handle the cast back automatically. The method to trigger all the business logic could also have its name standardised ("load", "fetch", "processData" etc.). Maybe we could also figure out a few other bits too. This would remove a lot of code, as well as making the code more readable (less messy), and make unit testing much easier. While it could never do everything automatically we could test the basic responses of each viewModel and have at least some testing done by default and not have everything be very boilerplate-y and copy / paste nature.

The guys think that subscribing to isSuccess and / or isError is perfect Rx + MVVM. But for some reason subscribing to status.filter(success) or status.filter(!success) is a sin of unimaginable proportions. Also the idea of multiple buttons and events all "reacting" to the same method named e.g. "load", is bad Rx (why if they all need to do the same thing?)

My thoughts on this are:

- To me its indentical in meaning and architecture, one way is just significantly less code.
- Lets say I agree its not textbook, is it not worth bending the rules to reduce code.
- We are already breaking the rules of MVVM to introduce coordinators (which I hate, as they are adding even more unnecessary code), so why is breaking it to reduce code such a no no.

Any thoughts on the above? Am I way off the mark or is this classic Rx?

I swear the God I'm considering getting a rabied dog just to bite your balls off in case I ever see you in the streets..

- guys X are running load tests on env A
- load tests complete
- analysis of test results is being done
- slow response times are obsered
- someone asks whether X guys took a thread dump for further analysis
- a guy from team X (Mr. Xx) replies: "Will take the Thread Dump now."
- 10 minutes later uploads the whole fucking 2GB log file to Slack
- Xx replies: "I do not see anything wrong in the dump"

A fucking retard... Shove that useless dump up your ass and THEN tell me there's nothing wrong with it! Why the FUCK do you think that's the case? Moron

Me: API support team, 3% of our requests to your API during a load test are getting ECONNTIMEDOUT errors. Can you check why is that?

API supp: Please check connectivity to our API

I don't know how it makes me feel, but it is not a good feeling.

That moment when your monitoring software breaks before your app in a load test

Is it just me or should a vendor be able to load test their own fucking product?

Fucking buffoons

Web Devs of Devrant, i have a question for you!

How to you efficiently test a website speed?
Sure i know about googles page insight, GTmatrix and all the other "free" testing tools.
But im more interested in a tool i can make run multiple times, and then get a avg (or at least some kind op spreadsheet) showing the time it taken to load - and the different parts.

Say i want a test to run 1 time every 5 min, 20 times - then get data for all those. Any tools that can make such data available to me?
Or should i look at some other tools?

Why the fuck open source solutions need to be such a load of bullcrap? I've spent a week trying to set up every single self-hosted video conference software, and the only thing I've got is a shorter lifespan.

How the fuck does your (judging by GitHub, well maintained) software only support Ubuntu 16.04? And I mean ONLY, there's no support for docker, or any other distro either, and we're only weeks from getting the second LTS since 16.04. And why the fuck does documentation tell me to manually go through 20 different config files just to enable SSL?

Why the fuck doesn't your official AWS cloudformation template include VPC or other required parameters? I've had to rewrite the whole thing just to get a valid stack you dipshit!

And how fucking hard is to make your software look decent, I can't expect clients to chat with me using something that looks like an incest child of 2003 MSN and eDonkey?

Oh, and it'd be fucking dandy if your documentation wouldn't return 404, maybe I'd be even able to test what your product has to offer?

I guess after everything I've tried I'll go with Jitsi; it seems the most decent, although it lacks some pretty basic features like limiting chat features for guests.

In last episode of "How SystemD screwed me over", we talked about Systemd's PrivateTMP and how it stopped me from generating SSL certificates.

In today's episode - SystemD vs CGroups!

Mister Pottering and his team apparently felt that CGroups are underused (As they can be quite difficult to set up), and so decided to integrate them into SystemD by default. As well as to provide a friendlier interface to control their values.

One can read about these interactions in the manual page "systemd.resource-control"

All is cool so far. So what happened to me today?

Imagine you did a major system release upgrade of a production server, previously tested on a standalone server. This upgrade doesn't only upgrade the distribution however, it also includes the switch from SysVInit to SystemD. Still, everything went smooth before, nothing to worry now then, right? Wrong.

The test server was never properly stress-tested. This would prove to be an issue.

When the upgrade finishes, it is 4 AM. I am happy to go to bed at last. At 6 AM, however, I am woken up again as the server's webservices are unavailable, and the machine is under 100% CPU load. Weird, I check htop and see that Apache now eats up all 32 virtual cores. So I restart it, casting it off to some weird bug or something as the load returns to normal.

2 hours later, however, the same situation occurs. This time, I scour all the logs I can, and find something weird - Many mentions that Apache couldn't create a worker thread? That's weird.

Several hours of research and tinkering later, I found out the following:
1 - By default, all processes of a system that runs SystemD are part of several CGroups. One of these CGroups is the PID CGroup, meant to stop a runaway process from exhausting all PIDs/TIDs of a system.

This limit is, by default, set to a certain amount of the total available PIDs. If a process exhausts this limit, it can no longer perform operations like fork().

So now, I know the how and why, but how should I solve this? The sanest option would be to get a rough estimate of just how many threads the Apache webserver might need. This option, though, is harder, than apparent. I cannot just take the MaxRequestsWorkers number... The instance has roughly double the amount of threads already. The cause being, as I found out, the HTTP/2 module, which spawns additional threads that do not count towards this limit. So I have no idea what limit to set.

Or I could... Disable the limit for just the webserver via the TasksAccounting switch. I thought this would work. And it did seem to... Until I ran out of TIDs again - Although systemctl status apache2.service no longer reported the number of tasks or a task limit of the process, the PID CGroup stayed set to the previous limit. Later I found out that I can only really disable the Task Accounting for all the units of a given slice and its parents.

This, though, systemctl somewhat didn't make apparent (And I skimmed the manual, that part was my fault)

So... The only remaining option I had was to... Just set the limit to infinite. And that worked, at last.

It took me several hours to debug this issue. And I once again feel like uninstalling systemd again, in favor of sysvinit.

What did I learn? RTFM, carefully, everything is important, it is not enough to read *half* the paragraph of a given configuration option...

Oh, and apache + http/2 = huge TID sink.

The Odyssey of the Tenacious Tester:

Once upon a time in the digital kingdom of Binaryburg, there lived a diligent software tester named Alice. Alice was on a mission to ensure the flawless functionality of the kingdom's latest creation – the Grand Software Citadel.

The Grand Software Citadel was a marvel, built by the brilliant developers of Binaryburg to serve as the backbone of all digital endeavors. However, with great complexity came an even greater need for meticulous testing.

Alice, armed with her trusty testing toolkit, embarked on a journey through the intricate corridors of the Citadel. Her first challenge was the Maze of Edge Cases, where unexpected scenarios lurked at every turn. With a keen eye and a knack for uncovering hidden bugs, Alice navigated the maze, leaving no corner untested.

As she progressed, Alice encountered the Chamber of Compatibility, a place where the Citadel's code had to dance harmoniously with various browsers and devices. With each compatibility test, she waltzed through the intricacies of cross-browser compatibility, ensuring that the Citadel would shine on every screen.

But the true test awaited Alice in the Abyss of Load and Performance. Here, the Citadel's resilience was put to the test under the weight of simulated user hordes. Alice, undeterred by the mounting pressure, unleashed her army of virtual users upon the software, monitoring performance metrics like a hawk.

In the end, after days and nights of relentless testing, Alice emerged victorious. The Grand Software Citadel stood strong, its code fortified against the perils of bugs and glitches.

To honor her dedication, the software gods bestowed upon Alice the coveted title of Bug Slayer and a badge of distinction for her testing prowess. The testing community of Binaryburg celebrated her success, and her story became a legend shared around digital campfires.

And so, dear software testers, let the tale of Alice inspire you in your testing quests. May your test cases be thorough, your bug reports clear, and your software resilient against the challenges of the digital realm.

In the world of software testing, every diligent tester is a hero in their own right, ensuring that the digital kingdoms stand tall and bug-free.

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)

v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- 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.

Load tests:

I'm used to do load tests in Visual Studio where it gives which line is exactly your bottleneck. But now I'm using VS Code (visual studio requires enterprise license for load tests :\ no longer have one)

Anyways long story short, what are the best practices for load tests? For me what I'm testing is how much can a given hardware specs handle and when test fails I go back and check if code can be optimized, is this the correct way to do this?

About to checkout Gatling for load test to my REST api, any other suggestions?

So far their docs look straightforward to follow, requires scala but it doesn't look that complicated for that particular case.

Dotnet core devs, do you recommend another tool?

Created a win7 vm for a test in an environment of all of Linux vms. Named it billgates. I'm 99% sure my other vms increased resource load in spite. There is a revolution brewing.

Programmer looking for a new language

I have been a JavaScript developer for a few years now (non professionally) and I really like the language. I mainly program for execution with NodeJS rather than web, because I feel like I get more freedom (e.i. the ability to use a computer file system).

I normally never use other people's libraries and instead either write my own library/ies for the specific task or use an old one. I only ever use someone else’s if I need a quick frame work to test an idea, never for something I will actually use.
I prefer to work object / class orientated.

I have worked on distributed servers with NodeJS before, however trying to distribute a load across one computer across it's multiple threads has proved problematic due to the heavy delays of standard io transfer speeds.

Why do I want to switch?:
•Because JavaScript is not at all created with multithreading in mind, and pretty much any multithreading solution is a bodge and allot of the time it is more efficient to work single threaded.
•Also, I get the sense that JavaScript + NodeJS is not used often in the programming industry comparison to other languages like; ruby, python, and I don't want to get stuck in a nesh language of which would decrease my employment chances heavy.

Side Note: I have been working on a pet project to have a distributed database (made with nodejs), and so far, there are no language specific problems, but I feel like it would be more efficient if I used a programming language designed more to cater for multi threading.

rent / question (there is a question at the end and I'd appreciate your opinion)

8 months ago, I agreed to help a not too distant relative of mine to do his master thesis at the company where I work. He was supposed to build something really MVP, but useful for us and I'd help him get some scientific questions out of it, and provide him with (computing) resources to test his theories / implementations under simulated and much heavier load.

Since then, he didn't get done anything even remotely useful, always just stuck on very rudimentary issues, claimed things are almost ready, I wrote a quick smoke test to prove that the whole application blows up when you touch it, in short - a disaster and went over to radio silence.

In the meanwhile, we didn't need it anymore, so 1.5 months ago, I got in touch with him again, with an even more technical proposal, something, at least I'd think, that's even cooler to do. He asked me some question about hypothetical load, the system should be able to handle eventually, to come up with alternative implementations to compare them against each other. He said that his exam period is going to be over soon and he'll get back to me with some initial version.

2 weeks ago, I got back in touch with him, trying to urge him, to get finally started and get something done. If he'd actually sit down and do it during the holidays as a "full time job", he'd be probably done in 2 weeks. Last week, he came back to me and said he has an initial PR ready to review.

I was excited about it, but basically froze when I realized what he did. He deleted all his previous work - some infrastructure stuff which took us basically 3 months of back and forth to get running - and as far as I could see, all the new code were only auto generated clients based on a swagger specification. In short - I could do it in less then an hour. If you really have no idea what you're doing, it might take you half a day, but definitely nowhere near to a week.

His brother, which a good friend of mine, thinks I'm being too hard on him. His argument was, that it's too hard, and he has to do it in C#, but he only knows Java (I gave him access to some of our repositories to copy paste code together, he didn't need to invent anything. I also prefer C# but wrote my master thesis in Java) Personally, I'm just pissed because he promises stuff that he never does. I totally understand him - I was like that as a student as well, I guess karma is a ... but still, he's wasting my time.

Right now I'm thinking how to get out of this, without having even more time wasted. I doubt he'd ever deliver anything useful. He got plenty of input from me about what he could consider for his scientific question, how to measure performance, ... He can keep his credentials to access our test environment with the test data, but I won't give him access to any additional computing resources, to compare how his solutions might scale on our company's cost. (mainly it's not the money, but I'd have to provide that stuff, and probably help him set it up)

does it sound like a fair deal (saying, I'm done with you. You can finish your topic on your own, but don't expect any help from me)? or am I being a dick about it and too demanding?

So, I have been working for a company XYZ for about 2 years now and for this 2 years, we are just two engineers handling everything. The job is becoming super stressful and time consuming, the founders dictates how the engineering team operate, ranging from choosing a third party service we are to integrate into the platform without letting us know and also study the api to see if it will be the most viable one to use.

Imagine using a third party service that you can't get through to when something is unclear?

I and my team mate has asked the founders to hire engineers so the work load on us will reduce, they said it's on their mind ( this request was made months ago), fast forward last week, we were told to start interviewing interns ( I don't have problem with interns working with us ), but what we asked for was experience engineers working with us but the founders did entire 180 degree of what we asked.

We have been asking for a QA Engineer for months and months now, all we get is we will hire one, and till now nothing is been done.

Following good software practice has been a problem in company XYZ, we have been finding it difficult to write test and documentation (this shit makes me seriously sick and hate myt po self).

On top of all this, the salary is shitty, there are no benefits, we are coerced into working during weekends (most times), and we are also told to work during our holiday, no single health insurance.

I think I have come to that point where I will have to say good bye ( but I am finding it difficult to do this).

Any suggestions ? Should I wait until I get another job and then I resign from company XYZ or just resign.

I learned to code on a jailbroken iPod touch around 2009. I wanted to compile some random project for jailbroken devices, but I had a windows comp (with dialup!!!), so I was like "why not do it on the iPod itself?". I didn't even have wifi, so I'd sneak out of my parents' house at night and steal the neighbor's (hey, I was 11 w/ overprotective parents who would freak out if I occupied the phone line w/ internet) to go read up on compilers, jailbreaking, etc etc. Eventually I got a working compiler and toolchain, but when I went to compile the project I wanted to use (and not just a test project that I found), it spat out errors. So I learned C/ObjC on my iPod. Turned out the project I was trying to compile was a load of BS, so I implemented my own version and put it on github. From a fuckin iPod. Win. It was some SBSettings control. Once upon a time, you had to jailbreak to get those cool slide up/down menus with the toggles for wifi, bluetooth, location, etc!!!

I want to make a phone designed for programming. I want to use something like the pine phone and either load or make a custom OS for this purpose. I've found my self sitting some where doing nothing and having an idea that I would like to test but either don't have a laptop or don't have the space to use my laptop (Lenovo x240). I would love to hear your suggestions for base phones and custom ROMS or OS to use. I am on a bit of a budget however I would be willing to spend a bit along as it's worth the price.

What the hell am I!? I wonder if you guys can help me...

I've been programming most of my life but I've never actually been a developer by title or job role. I thought maybe if I list what I do and have done someone here could help? I'm sure there are more of you in a similar boat.

- C# and VB dev for some quick DBMS projects to help me understand and mine databases and create a nice simple view for project teams to show findings from the data to help make certain decisions.
- Automating a lot of my colleagues work with Python and if very restricted then just VBA macros in Excel and MSP. This did also include creating tools to gather data during workshops and converting the data for input into other systems.
- Brought Linux to the office with most team members now moving over to Linux with the peace of mind to know that though they do need to try solve their own problems, I can help if need be.
- Had to learn AWS and then implement an autoscaling and load balanced data center installation of a few Atlassian toolsets.
- Creating the architecture diagrams documentation needed for things like the above point.
- Having said that, also have ended up setting up all the Jira/Confluence etc. servers we use and have implemented so far whether cloud (Azure/AWS) or on prem and set up scripts to automate where possible.
- Implemented an automated workflow view in SharePoint based on SP list data and though in an ASPX page, primarily built in JS.
- Building test systems in PHP/JS with Laravel and Angular to help manage integration between systems. Having quite a time right looking into how to build middleware to connect between SOAP and REST API's, the trouble caused more by the systems and their reliance on frameworks we're trying to cut out of the picture.
- Working on BI and MI and training a team to help on the report creation so that I can do the fun creative stuff and then set them to work on the detail :)

Actually it seems safe to say that it seems that though I've finally moved into a dev office (beforehand being the only developer around) I seem to be the one they go to when a strategic solution is needed ASAP and the normal processes can't be followed (fun for someone with a CompSci degree and a number of project management courses under the belt... though I honestly do enjoy the challenges)

But I always end up Jack of all but master of, well hopefully some at least. let's not even get started on the tech related hobbies from circuit design and IoT to Andoid / iOS and game dev and enjoying a bit of pen testing to make sure we're all safe at work and at home.

As much as I don't like boxes, I'm interested to know if there is in fact a box for me? By the way, the above is just a snapshot of my last two years minus the project management work...

How the fuck you people do load testing ?

Don't tell me JMeter, it's useless as it doesn't represent an actual browser session...

I'm not taliong "test APIs" but the whole user experiance....

Can't find a single tool which does it at 1000+ sessions....

Darn xml config file for a dll wouldn't load.

1) Searching Stackoverflow which says that only configs for exe files are loaded. Problem found and time to send bug report? Nah, better check source code first.

2) Downloading and reading the source for the dll. Nope, dll should explicitly load config file and read settings. Time to send problem report to author? Nah, better to test in greater isolation first.

3) Setting up isolated test. About to copy the LibName.dll.config.xml and WHAT? Note to self: You half witted twat, the file contents is XML, the bloody file extension isn't!

Now apply this sort of typo error to program code, and you will see why I use statically typed languages.

Fuck me Amazon cert manager is so fucking complicated. Just do it all for me; why do i have to providing a route 53 entry (TECHNICALLY 2 IF I WANT MY NAME CORRECT) BEFORE I set up my load balancer??!! I should be able to test a load balancer first and then add on tls, not have to get a cert all set up and then sit on my fucking ass when the load balancer shits itself

I'm not experienced in VB Forms. So can someone who is, tell me if I'm just too inexperienced or if Im right about this?
Im tasked with fixing some bugs in a VB Forms project that a privious employee wrote some years ago. When I opened the project and checked it out, there was over 5600 lines of code in the codebehind for the form.
I feel like this is somewhat bad practice, no comments, no documentation... Nothing. And to top it off, among the worst naming of Subs and variables ever. Stuff like: "Run", "Stop", "Feeder", "When Load".
Oh, and the best part? The guy forgot some test code in the software, so when he left, the software stoped functioning. For real, he coded in a dependency to his own account in The AD.

At last, I'm doing some unknown stuff. We are using Terraform, to create our load balancers and them, kops to deploy our stateless services inside K8 clusters and Jaeger to trace requests end to end (and being able to test/debug our services).
Next step will be using gRPC for our RPC API.
Pretty cool

Another disaster of 2020 had struck.
The internet is fucked again. This time of a global scale. Did you grow a bit suspicious why everything takes more to load? USA is getting ddosed by china again... I get dns proube failed error on every website and things that work are as fast as that inter your company have hired for thag cobol project from 1876. I have a online test tomorrow, usa can you fucking get ddosed later?

Yep and the attack is currently shown on the famous ddos graph web site

When the vendor did a search page but retrieve all the records from the database and paginate them with js, and the load test crashes with 20 concurrent users!!!
