So I got the job. Here's a story, never let anyone stop you from accomplishing your dreams!
It all started in 2010. Windows just crashed unrecoverably for the 3rd time in two years. Back then I wasn't good with computers yet so we got our tech guy to look at it and he said: "either pay for a windows license again (we nearly spend 1K on licenses already) or try another operating system which is free: Ubuntu. If you don't like it anyways, we can always switch back to Windows!"
Oh well, fair enough, not much to lose, right! So we went with Ubuntu. Within about 2 hours I could find everything. From the software installer to OpenOffice, browsers, email things and so on. Also I already got the basics of the Linux terminal (bash in this case) like ls, cd, mkdir and a few more.
My parents found it very easy to work with as well so we decided to stick with it.
I already started to experiment with some html/css code because the thought of being able to write my own websites was awesome! Within about a week or so I figured out a simple html site.
Then I started to experiment more and more.
After about a year of trial and error (repeat about 1000+ times) I finally got my first Apache server setup on a VirtualBox running Ubuntu server. Damn, it felt awesome to see my own shit working!
From that moment on I continued to try everything I could with Linux because I found the principle that I basically could do everything I wanted (possible with software solutions) without any limitations (like with Windows/Mac) very fucking awesome. I owned the fucking system.
Then, after some years, I got my first shared hosting plan! It was awesome to see my own (with subdomain) website online, functioning very well!
I started to learn stuff like FTP, SSH and so on.
Went on with trial and error for a while and then the thought occured to me: what if I'd have a little server ONLINE which I could use myself to experiment around?
First rented VPS was there! Couldn't get enough of it and kept experimenting with server thingies, linux in general aaand so on.
Started learning about rsa key based login, firewalls (iptables), brute force prevention (fail2ban), vhosts (apache2 still), SSL (damn this was an interesting one, how the fuck do you do this yourself?!), PHP and many other things.
Then, after a while, the thought came to mind: what if I'd have a dedicated server!?!?!?!
I ordered my first fucking dedicated server. Damn, this was awesome! Already knew some stuff about defending myself from brute force bots and so on so it went pretty well.
Finally made the jump to NginX and CentOS!
Made multiple VPS's for shitloads of purposes and just to learn. Started working with reverse proxies (nginx), proxy servers, SSL for everything (because fuck basic http WITHOUT SSL), vhosts and so on.
Started with simple, one screen linux setup with ubuntu 10.04.
Running a five monitor setup now with many distro's, running about 20 servers with proxies/nginx/apache2/multiple db engines, as much security as I can integrate and this fucking passion just got me my first Linux job!
It's not just an operating system for me, it's a way of life. And with that I don't just mean the operating system, but also the idea behind it :).20 -
--- HTTP/3 is coming! And it won't use TCP! ---
A recent announcement reveals that HTTP - the protocol used by browsers to communicate with web servers - will get a major change in version 3!
Before, the HTTP protocols (version 1.0, 1.1 and 2.2) were all layered on top of TCP (Transmission Control Protocol).
TCP provides reliable, ordered, and error-checked delivery of data over an IP network.
It can handle hardware failures, timeouts, etc. and makes sure the data is received in the order it was transmitted in.
Also you can easily detect if any corruption during transmission has occurred.
All these features are necessary for a protocol such as HTTP, but TCP wasn't originally designed for HTTP!
It's a "one-size-fits-all" solution, suitable for *any* application that needs this kind of reliability.
TCP does a lot of round trips between the client and the server to make sure everybody receives their data. Especially if you're using SSL. This results in a high network latency.
So if we had a protocol which is basically designed for HTTP, it could help a lot at fixing all these problems.
This is the idea behind "QUIC", an experimental network protocol, originally created by Google, using UDP.
Now we all know how unreliable UDP is: You don't know if the data you sent was received nor does the receiver know if there is anything missing. Also, data is unordered, so if anything takes longer to send, it will most likely mix up with the other pieces of data. The only good part of UDP is its simplicity.
So why use this crappy thing for such an important protocol as HTTP?
Well, QUIC fixes all these problems UDP has, and provides the reliability of TCP but without introducing lots of round trips and a high latency! (How cool is that?)
The Internet Engineering Task Force (IETF) has been working (or is still working) on a standardized version of QUIC, although it's very different from Google's original proposal.
The IETF also wants to create a version of HTTP that uses QUIC, previously referred to as HTTP-over-QUIC. HTTP-over-QUIC isn't, however, HTTP/2 over QUIC.
It's a new, updated version of HTTP built for QUIC.
Now, the chairman of both the HTTP working group and the QUIC working group for IETF, Mark Nottingham, wanted to rename HTTP-over-QUIC to HTTP/3, and it seems like his proposal got accepted!
So version 3 of HTTP will have QUIC as an essential, integral feature, and we can expect that it no longer uses TCP as its network protocol.
We will see how it turns out in the end, but I'm sure we will have to wait a couple more years for HTTP/3, when it has been thoroughly tested and integrated.
Thank you for reading!27 -

This was over a year ago now, but my first PR at my current job was +6,249/-1,545,334 loc. Here is how that happened... When I joined the company and saw the code I was supposed to work on I kind of freaked out. The project was set up in the most ass-backward way with some sort of bootstrap boilerplate sample app thing with its own build process inside a subfolder of the main angular project. The angular app used all the CSS, fonts, icons, etc. from the boilerplate app and referenced the assets directly. If you needed to make changes to the CSS, fonts, icons, etc you would need to cd into the boilerplate app directory, make the changes, run a Gulp build that compiled things there, then cd back to the main directory and run Grunt build (thats right, both grunt and gulp) that then built the angular app and referenced the compiled assets inside the boilerplate directory. One simple CSS change would take 2 minutes to test at minimum.
I told them I needed at least a week to overhaul the app before I felt like I could do any real work. Here were the horrors I found along the way.
- All compiled (unminified) assets (both CSS and JS) were committed to git, including vendor code such as jQuery and Bootstrap.
- All bower components were committed to git (ALL their source code, documentation, etc, not just the one dist/minified JS file we referenced).
- The Grunt build was set up by someone who had no idea what they were doing. Every SINGLE file or dependency that needed to be copied to the build folder was listed one by one in a HUGE config.json file instead of using pattern matching like `assets/images/*`.
- All the example code from the boilerplate and multiple jQuery spaghetti sample apps from the boilerplate were committed to git, as well as ALL the documentation too. There was literally a `git clone` of the boilerplate repo inside a folder in the app.
- There were two separate copies of Bootstrap 3 being compiled from source. One inside the boilerplate folder and one at the angular app level. They were both included on the page, so literally every single CSS rule was overridden by the second copy of bootstrap. Oh, and because bootstrap source was included and commited and built from source, the actual bootstrap source files had been edited by developers to change styles (instead of overriding them) so there was no replacing it with an OOTB minified version.
- It is an angular app but there were multiple jQuery libraries included and relied upon and used for actual in-app functionality behavior. And, beyond that, even though angular includes many native ways to do XHR requests (using $resource or $http), there were numerous places in the app where there were `XMLHttpRequest`s intermixed with angular code.
- There was no live reloading for local development, meaning if I wanted to make one CSS change I had to stop my server, run a build, start again (about 2 minutes total). They seemed to think this was fine.
- All this monstrosity was handled by a single massive Gruntfile that was over 2000loc. When all my hacking and slashing was done, I reduced this to ~140loc.
- There were developer's (I use that term loosely) *PERSONAL AWS ACCESS KEYS* hardcoded into the source code (remember, this is a web end app, so this was in every user's browser) in order to do file uploads. Of course when I checked in AWS, those keys had full admin access to absolutely everything in AWS.
- The entire unminified AWS Javascript SDK was included on the page and not used or referenced (~1.5mb)
- There was no error handling or reporting. An API error would just result in nothing happening on the front end, so the user would usually just click and click again, re-triggering the same error. There was also no error reporting software installed (NewRelic, Rollbar, etc) so we had no idea when our users encountered errors on the front end. The previous developers would literally guide users who were experiencing issues through opening their console in dev tools and have them screenshot the error and send it to them.
- I could go on and on...
This is why you hire a real front-end engineer to build your web app instead of the cheapest contractors you can find from Ukraine.19 -
Its that time of the morning again where I get nothing done and moan about the past ... thats right its practiseSafeHex's most incompetent co-worker!!!
Today I'd like to tell you the story of "i". Interesting about "I" is that he was actually a colleague of yesterdays nominee "G" (and was present at the "java interface" video call, and agreed with G!): https://devrant.com/rants/1152317/...
"I" was the spearhead of a project to end all projects in that company. It was suppose to be a cross-platform thing but ended up only working for iOS. It was actually quite similar to this: https://jasonette.com/ (so similar i'm convinced G / I were part of this but I can't find their github ID's in it).
To briefly explain the above + what they built ... this is the worst piece of shit you can imagine ... and thats a pretty strong statement looking back at the rest of this series so far!
"I" thought this would solve all of our problems of having to build similar-ish apps for multiple customers by letting us re-use more code / UI across apps. His main solution, was every developers favourite part of writing code. I mean how often do you sit back and say:
"God damn I wish more of this development revolved around passing strings back and forth. Screw autocomplete, enums and typed classes / variables, I want more code / variables inside strings in this library!"
Yes thats right, the main part of this bullshittery was putting your entire app, into JSON, into a string and downloading it over http ... what could possibly go wrong!
Some of my issues were:
- Everything was a string, meaning we had no autocomplete. Every type and property had to be remembered and spelled perfectly.
- Everything was a string so we had no way to cmd + click / ctrl + click something to see somethings definition.
- Everything was a string so any business logic methods had to be remembered, all possible overloaded versions, no hints at param types no nothing.
- There was no specific tooling for any of this, it was literally open up xcode, create a json file and start writing strings.
- We couldn't use any of the native UI builders ... cause strings!
- We couldn't use any of the native UI layout constructs and we had to use these god awful custom layout managers, with a weird CSS feel to them.
What angered me a lot was their insistence that "You can download a new app over http and it will update instantly" ... except you can't because you can't download new business logic only UI. So its a new app, but must do 100% exactly the same thing as before.
His other achievements include:
- Deciding he didn't like apple's viewController and navigationBar classes and built his own, which was great when iOS 7 was released (changed the UI to allow drawing under the status bar) and we had no access to any of apples new code or methods, meaning everything had to be re-built from scratch.
- On my first week, my manager noticed he fucked up the login error handling on the app I was taking over. He noticed this as I was about to leave for the evening. I stayed so we could call him (he was in an earlier timezone). Rather than deal with his fucked up, he convinced the manager it would be a "great learning experience" for me to do it ... and stay in late ... while he goes home early.
- He once argued with me in front of the CEO, that his frankenstein cross-platform stuff was the right choice and that my way of using apples storyboards (and well thought out code) wasn't appropriate. So I challenged him to prove it, we got 2 clients who needed similar apps, we each did it our own way. He went 8 man weeks over, I came in 2 days under and his got slated in the app store for poor performance / issues. #result.
But rather than let it die he practically sucked off the CEO to let him improve the cross platform tooling instead.
... in that office you couldn't swing a cat without hitting a retard.
Having had to spend a lot more time working with him and more closely than most of the other nominees, at a minimum "I" is on the top of my list for needing a good punch in the face. Not for being an idiot (which he is), not for ruining so much (which he did), but for just being such an arrogant bastard about it all, despite constant failure.
Will "I" make it to most incompetent? Theres some pretty stiff competition so far
Tune in later for more practiceSafeHex's most incompetent co-worker!!!6 -

So I was hired about 4 months or so in this companty, we will name it 'Derp & Co.'
The first task they want me to do was to 'clean' an android app that, for what they told me:
- Previous dev fired. said that tasks have been done but totally a lie.
- Took a fully week of 2 fellows coworkers to 'undo' the mess.
- And for the last but not least, zero documentation, like ZERO.
So, I clone the repo, install android studio, blah blah blah, get hands to the pile of code and jesus...
- The whole app was working with a gargantuan json, there was no use of POJOs at all. Objects are for normies.
- A masive copy/paste code, like 'I will need this here, crtl-c... ctrl-v, DONE!'
- Threads are free, isn't it? let's just put a thread whenever I desire to make an HTTP request and not reuse code at all.
So... with this on mind, my first task is to make proper objects:
- Coworker: 'Sorry dev, we don't have documentation for this, you must debug the code to se what the server will send to you'.
- Me: 'Real?'
Shit... ok. So I first try to figure out how the hell is made my gargantuan json. A month was entirely lost to unravel this data and implement Objects, improve their code, reuse code, etc. but at the very end:
- coworker: 'Good job dev, when the POJOs are done, we can focus on the next task, whe have to define a new DATA MODEL because the one we are using now is not good at all'.
*note: the app is on production and working with all the previous 'features' and today it still on use on some enviroments.
- Me: 'Wait... this is a joke, now you want to define new data models? This should have been done in first place!' <WTF face>
- Coworker: 'I don't think so dev, Mr. boss have this list with things to improve on the app an this is the order of do the tasks'.
Mr. boss is on vacations, two days after he came back:
- Mr boss: 'Coworker said that you have been working with POJOs, is that right?'
- Me: 'Yes'
- Mr boss: 'Why? Did not see the need of a new data model?'
- Me: 'I told that to him, but he insist on "the order" of the list.
- Mr. boss <facepalm>
This is one of the few tales i have from 'Derp & Co.'
PS: Sorry if i made a mistake on writing, english is not my first language and maybe I have done some mistakes.7 -

Best non-technical description of why we hate to post in forums (shamelessly copied from Shamus Youngs blog found here: http://shamusyoung.com/twentysidedt...) ->
ALLEN: Hi, I’m new to driving and I need to move my car back around 5 meters. How can I move the car backwards?
(2 days later.)
ALLEN: Hello? This is still a problem. I’m sure someone knows how to do this.
BOB: I can’t believe you didn’t figure this out yourself. Just take your foot off the gas and let the car roll backwards down the hill. Tap the bake when you get to where you want to be. Boom. Done.
ALLEN: But I’m not on a hill. I’m in my driveway and it’s completely flat.
CARL: Dude, I don’t know what you’re trying to accomplish, but you should never be driving backwards. It’s dangerous and will confuse the other drivers. See the big window in FRONT of you? That’s your first clue. Don’t drive backwards.
ALLEN: I’m not trying to drive backwards. I just need to move back a little bit so I can get out of my driveway and start driving forwards.
CARL: So just drive in circle until you’re pointed the right way.
ALLEN: I don’t have enough room to turn around like that. I only need to move back a few meters. I don’t understand why this has to be so hard.
CARL: Sounds like your “driveway” isn’t compatible with cars. It’s probably made for bikes. Call a contractor and have them convert some of your yard into driveway to be standards-compliant with the turning radius of a car. Either way, you’re doing something wrong.
DAVE: I see your problem. You can adjust your car to move backwards by using the shifter. It’s a stick located right between the passenger and driver seats. Apply the clutch and move the stick to the “R” position.
ALLEN: But.. I don’t have a clutch. And there isn’t a stick between the seats.
CARL: Sounds like you’re trying to drive in Europe or something.
ALLEN: Ah. Nevermind. I figured it out.8 -
Background: I'm not drunk yet, BUT I'M WORKING ON IT.
okay.
I just finished a second sprint on my React app. The first was to build a merchant onboarding flow. The second was to do substantial cleanup as I learned more about react/redux, and to create a "supply order" flow -- basically purchasing marketing materials and services. I finished that in a week, and I'm pretty proud. api-guy wanted it done in a day. i laughed. he probably could have, but it would have been a copy of the code in a new repo with some lines changed.
ANYWAY. it's all done and It's super pretty and works amazingly well. It has both the onboarding flow and the ordering flow, with a nice pop-out sidebar for navigation, namespaced actions, etc. Everything is pretty clean. I even added a cart to the ordering (despite everyone telling me not to) because wtf, what if someone wants to order TWO items? dumbasses. So I made that. it's sexy.
Anyway, it's all done and shiny and fancy and wonderful and I'd *love* to share screenshots if only it didn't give away where I worked. :<
... but the point of the rant!
After the first sprint, I made a copy of the repo so I could rework it and add more functionality without touching the original. (Hey! That's what a branch is for, right? Why didn't I branch it up?
well, read on)
I knew we were going to have multiple separate flows for this app: onboard, ordering, merchant tools, admin tools, support, etc. So, I wrote its server portion (the webpack builder + http server) so it would serve the same app at whatever url the user hit, and set a cookie containing that host+url. This allows the app to serve different content (basically showing/hiding content) based on the URL and future login roles. If someone hits /order, it would hide everything but the order flow. If they're a merchant, it would show all the merchant views plus ordering, etc.
tl;dr This way I can use the same codebase for multiple sites, drastically simplifying development, branding, and what have you. This new app could obv also be a drop-in replacement for the original onboarding project because of the above.
HOWEVER. this apparently isn't good enough for api-guy. He's terrified that adding/updating future components will affect all the existing content somehow.
so.
now we have three repos for basically the same codebase. 1) onboard aka "surfboard", 2) ordering, 3) merchant tools, aka "ferrari" (the "future" app).
Except.
1) "surfboard" is a very old version of the code. 3) "ferrari" is also old, since 2) "ordering" has newer content in it now.
... and somehow this is better?
fuck if i can figure out how.
His reasoning is "well, you won't be touching surfboard or ordering for 6 months, so now you don't have to worry about it." Sure, except, you know, it'll be a pain in the ass in 6 months now when I have a crapton of code and branding to redo. ffs.
Oh. We also have three Heroku pipelines for these three repos. for the same codebase.
and now you know why i'm drinking.undefined idiocy fucking hell fuck this noise api guy i'm just gonna replace everything later this codebase is as dry as the friggin ocean7 -
Yesterday the web site started logging an exception “A task was canceled” when making a http call using the .Net HTTPClient class (site calling a REST service).
Emails back n’ forth ..blaming the database…blaming the network..then a senior web developer blamed the logging (the system I’m responsible for).
Under the hood, the logger is sending the exception data to another REST service (which sends emails, generates reports etc.) which I had to quickly re-direct the discussion because if we’re seeing the exception email, the logging didn’t cause the exception, it’s just reporting it. Felt a little sad having to explain it to other IT professionals, but everyone seemed to agree and focused on the server resources.
Last night I get a call about the exceptions occurring again in much larger numbers (from 100 to over 5,000 within a few minutes). I log in, add myself to the large skype group chat going on just to catch the same senior web developer say …
“Here is the APM data that shows logging is causing the http tasks to get canceled.”
FRACK!
Me: “No, that data just shows the logging http traffic of the exception. The exception is occurring before any logging is executed. The task is either being canceled due to a network time out or IIS is running out of threads. The web site is failing to execute the http call to the REST service.”
Several other devs, DBAs, and network admins agree.
The errors only lasted a couple of minutes (exactly 2 minutes, which seemed odd), so everyone agrees to dig into the data further in the morning.
This morning I login to my computer to discover the error(s) occurred again at 6:20AM and an email from the senior web developer saying we (my mgr, her mgr, network admins, DBAs, etc) need to discuss changes to the logging system to prevent this problem from negatively affecting the customer experience...blah blah blah.
FRACKing female dog!
Good news is we never had the meeting. When the senior web dev manager came in, he cancelled the meeting.
Turned out to be a hiccup in a domain controller causing the servers to lose their connection to each other for 2 minutes (1-minute timeout, 1 minute to fully re-sync). The exact two-minute burst of errors explained (and proven via wireshark).
People and their petty office politics piss me off.2 -

The solution for this one isn't nearly as amusing as the journey.
I was working for one of the largest retailers in NA as an architect. Said retailer had over a thousand big box stores, IT maintenance budget of $200M/year. The kind of place that just reeks of waste and mismanagement at every level.
They had installed a system to distribute training and instructional videos to every store, as well as recorded daily broadcasts to all store employees as a way of reducing management time spend with employees in the morning. This system had cost a cool 400M USD, not including labor and upgrades for round 1. Round 2 was another 100M to add a storage buffer to each store because they'd failed to account for the fact that their internet connections at the store and the outbound pipe from the DC wasn't capable of running the public facing e-commerce and streaming all the video data to every store in realtime. Typical massive enterprise clusterfuck.
Then security gets involved. Each device at stores had a different address on a private megawan. The stores didn't generally phone home, home phoned them as an access control measure; stores calling the DC was verboten. This presented an obvious problem for the video system because it needed to pull updates.
The brilliant Infosys resources had a bright idea to solve this problem:
- Treat each device IP as an access key for that device (avg 15 per store per store).
- Verify the request ip, then issue a redirect with ANOTHER ip unique to that device that the firewall would ingress only to the video subnet
- Do it all with the F5
A few months later, the networking team comes back and announces that after months of work and 10s of people years they can't implement the solution because iRules have a size limit and they would need more than 60,000 lines or 15,000 rules to implement it. Sad trombones all around.
Then, a wild DBA appears, steps up to the plate and says he can solve the problem with the power of ORACLE! Few months later he comes back with some absolutely batshit solution that stored the individual octets of an IPV4, multiple nested queries to the same table to emulate subnet masking through some temp table spanning voodoo. Time to complete: 2-4 minutes per request. He too eventually gives up the fight, sort of, in that backhanded way DBAs tend to do everything. I wish I would have paid more attention to that abortion because the rationale and its mechanics were just staggeringly rube goldberg and should have been documented for posterity.
So I catch wind of this sitting in a CAB meeting. I hear them talking about how there's "no way to solve this problem, it's too complex, we're going to need a lot more databases to handle this." I tune in and gather all it really needs to do, since the ingress firewall is handling the origin IP checks, is convert the request IP to video ingress IP, 302 and call it a day.
While they're all grandstanding and pontificating, I fire up visual studio and:
- write a method that encodes the incoming request IP into a single uint32
- write an http module that keeps an in-memory dictionary of uint32,string for the request, response, converts the request ip and 302s the call with blackhole support
- convert all the mappings in the spreadsheet attached to the meetings into a csv, dump to disk
- write a wpf application to allow for easily managing the IP database in the short term
- deploy the solution one of our stage boxes
- add a TODO to eventually move this to a database
All this took about 5 minutes. I interrupt their conversation to ask them to retarget their test to the port I exposed on the stage box. Then watch them stare in stunned silence as the crow grows cold.
According to a friend who still works there, that code is still running in production on a single node to this day. And still running on the same static file database.

In reply of a great discussion @mojoJojo started on Google's advertising ethics...
GOOGLE Already Pays AdBlock Extensions to Unblock Their Ads. This has been going on for years. Most of the large tech conglomerates have no morals and no ethics, if you ask me. To everyone saying "Oh, Google wouldn't do that" - they already do.

Recap: https://www.devrant.io/rants/878300
I was out Thursday at the Hospital. I'm what the doctors would call "Ill as fuck"
So, Friday I’m back in the office to the usual: "How was that appointment?"
I know people mean well when they ask this. So, I do the polite thing and tell them it went as well as it could.
Realistically it does't matter how well it went... They haven't cured Crohn's because I showed up to the appointment. They know I'm fucked already.
But, push it down, add it to the future aneurism.
I had to go through the usual resignation meetings with managers:
"We"re fucked now you're going"
"yep"
"we need to get a handle on how fucked"
"already done that for you, here"s a trello board, very fucked."
"we need to put a plan together to drop all the junior devs in the shit with the work you’ve been doing"
"You need about 4 devs, please refer to the previous trello board for your plan"
Meanwhile, me and Morpheus are in constant communication because all of this is like a Shakespearean comedy.
So, I overhear a conversation between a Junior Dev and the Solution Architect.
[SA] took over the project because he knows better than two tried and tested senior devs -_- (fuckwit).
JD: "It took me one and a half days to build it out"
SA: "Yeah, it must have taken me twice as long... It must be a problem with the project, you should just be able to check it out and run it."
JD: "I know, it has to be wrong"
All of this is about Morpheus' work of art, of an Ionic 3 hybrid app.
I fumed quietly at my desk because I've been ordered by the Stazi to be hands off.
Since Morpheus and me were pulled from the project [JD] and [JD2] were dropped into it to get it over the line.
It"s unfortunate and I was clear and honest with my advice to them: I personally would not take over the project because I"d be way out of my depth... Oh, and the App works, so uh, there's no work to do.
They have been constantly at our desks. Asking fuckdiculous questions about how to perform basic tasks. So they can get Morpheus" frigging masterpiece to the user.
It"s like watching that touch up of jesus that got borked by an amateur. Shit I have google, it's like watching this happen: http://ti.me/NnNSAb
[JD] came to me Friday evening.
"I can’t get this to build to iOS or install on [Test Analyst]'s phone."
Me: "No worries brother, where are you stuck right now?"
[JD] describes the first steps with clear indication he hasn't googled his problem.
Life lesson: http://lmgtfy.com/?q=lmgtfy
Que an hour of me showing [JD] how to build an Ion3 project for iOS. Fuck it, your man's in a bind and he"s asked politely for help. I can show him quicker than he can read 3 sets of docos.
I took him through 'ionic cordova build ios', the archive and release processes in XCode 9, then the apk bundling process for droid. Finally we have an MAM so the upload process for that too.
All the while cleaning up his AppIDs, Profiles, deployment attempts.
Damn they were a mess.
I did this with a smile on my face, not because I could say "I told you so"... But. because when any developer asks you how to do something. If you know how to do it, you should always be happy to learn them some new tricks!
Dude's alright, he's been dropped in the shit. Now I know how badly so I'll help him learn things that are useful to his role, but aren't project specific.
As a plausi-senior dev (I'll tell you about that later); it's my job to make sure my team have what they need to go home smiling!
I’m not a hateful fucker, the guy asked me an honest question so I am happy to give him the honest answer.
I took him through it a few times and explained a few best practices. Most were how to do his AppID and ProvProfile set up. Good lad, took it all on board.
However! In his frustration, he pointed the finger at Morpheus' "David" (ref: Michelangelo).
He miraculously morphed into a shiny colourful parrot and fed me SA's line:
"you should just be able to build from a clean clone"
My response was calm and clear:
"You can, it took me 20 minutes on Thursday evening. I was bored and curios, so I wanted to validate Morpheus' work. Here it is on my iOS device and my Android device. It would have taken me 5 if my laptop wasn’t so horrifically out of date."
I validated Morpheus' work so I have evidence, I trust that brilliant bastard.
I just need to be able to prove it's good.
[JD] took this on board.
Maybe listening to two tried and trusted senior devs is better than listening to a headstrong Solution Architect.
When JD left for the weekend I was working a late one (https://www.devrant.io/rants/874765).
His sign off was beautiful.
"I think I can happily admit defeat on this one, it can wait until Monday."
To which I replied: "no worries brother, if you need a hand give me a shout."
Rule 1: Don't be a cunt.
Rule 2: If someone needs help and you can give it: Give it!
Rule 3: Don't interrupt James' cigarette time.
Rule 4: goto Rule 3.rant day 3 jct resigns crohns resignation solution architect wk71 invisible illness fuckwit illness junior developer4 -
I'm thinking about doing a live coding stream on twitch this saturday, late afternoon or evening (CET).
I've never done a live stream before.
Do you have any suggestions or interests?
I'm thinking about something like a small RESTful API with Angular4/TypeScript (frontend, single page application) and CraftCMS/PHP (backend) with somebasic theory about HTTP requests / response, redirecting, data transfer and interfaces et cetera...
The duration will be around 2-4 hours, maybe longer if I have enough Mate & Beer.
But it's all just an idea at the moment. 😉
I will create an empty project for the stream on my Github and push to it during streaming, so you can pull it live or later.17 -

A rather long(it's 8 hrs long to be precise) story
So I just finished an amazing homework assignment. The goal was to open a new shell on Linux using a C program. We were asked to follow instructions from http://phrack.org/issues/49/14.html . However the instructions given were for 32 bit processors and we had to do same for 64 bit machines. In a nutshell we had to write a 64 bit shell code and use buffer-overflow technique to change the return address if the function to our shell code.
I was able to write my own shellcode within 1hr and was able to confirm that it's working by compiling with nasm and all. Also the "show-off-dev" inside me told me to execute "/bin/bash" instead of "/bin/sh"(which everyone else was going to do). After my assembly code was properly executing shellcode, I was excited to put it in my C code.
For that, I needed opcodes of assembly code in a string. Following again the "show-off-dev" inside me, I wrote a shell script which would extract the exact opcodes out of objdump output. After this I put it in my C code, call my friend and tell him that "hell yeah bro, I did it. Pretty sure sir is gonna give me full marks etc etc etc". I compiled the code and BOOM, IT SEGFAULTS RIGHT IN FRONT OF MY FRIEND. Worst, friend had copied a "/bin/sh" code from shellstorm and already had it working.
Really burned my ego, I sat continuously for 8 hrs in front of my laptop and didn't talk to anyone. I was continuously debugging the code for 8 hrs. Just a few minutes ago, I noticed that the shellcode which I'm actually putting in my C code is actually 2 bytes shorter than actual code length. WHAT THE F. I ran objdump manually and copied the opcodes one by one into the string (like a noob) and VOILA ! IT WORKED !!!
TURNS OUT I DIDN'T CUT THE LAST COLUMN OF OPCODES IN MY SHELL SCRIPT. I FIXED THAT AND IT WORKED !!
THE SINGLE SHITTY NUMBER MADE ME STRUGGLE 8 HRS OF MY LIFE !! SMH
Lessons learnt :
1)Never have such an ego that makes you think you're perfect, cuz you're retarded not perfect
2)Examine your scripts properly before using them
3)Never, I repeat NEVER!! brag about your code before compiling and testing it.
That's it!
If you've read this long story, you might as well press the "++" button.6 -
Today we presented our project in Embedded Systems. We made our so called "Blinkdiagnosegerät" (blink diagnosis device) which is used to get error codes from older verhicles which use the check enginge light to output the error. (for reference: http://up.picr.de/7461761jwd.jpg ) This was common for vehicles without OBD.
We made our own PCB, made a small database for 2 vehicles and used a Suzuki Samurai instrument cluster for the presentation (hooked up to an Arduino UNO and a relay for emulating some Error Codes)
Got an 1.0 (A) for the project. Feel proud for the first project done in C++ and making our own PCB. So no rant, just a good day after all the stress in the last weeks doing all assignements and presentations.
Next week we hopefully finish our inverse pendulum in Simulink and then the exams are close. :D19 -
Okay guys, this is it!
Today was my final day at my current employer. I am on vacation next week, and will return to my previous employer on January the 2nd.
So I am going back to full time C/C++ coding on Linux. My machines will, once again, all have Gentoo Linux on them, while the servers run Debian. (Or Devuan if I can help it.)
----------------------------------------------------------------
So what have I learned in my 15 months stint as a C++ Qt5 developer on Windows 10 using Visual Studio 2017?
1. VS2017 is the best ever.
Although I am a Linux guy, I have owned all Visual C++/Studio versions since Visual C++ 6 (1999) - if only to use for cross-platform projects in a Windows VM.
2. I love Qt5, even on Windows!
And QtDesigner is a far better tool than I thought. On Linux I rarely had to design GUIs, so I was happily surprised.
3. GUI apps are always inferior to CLI.
Whenever a collegue of mine and me had worked on the same parts in the same libraries, and hit the inevitable merge conflict resolving session, we played a game: Who would push first? Him, with TortoiseGit and BeyondCompare? Or me, with MinTTY and kdiff3?
Surprise! I always won! 😁
4. Only shortly into Application Development for Windows with Visual Studio, I started to miss the fun it is to code on Linux for Linux.
No matter how much I like VS2017, I really miss Code::Blocks!
5. Big software suites (2,792 files) are interesting, but I prefer libraries and frameworks to work on.
----------------------------------------------------------------
For future reference, I'll answer a possible question I may have in the future about Windows 10: What did I use to mod/pimp it?

No matter how much fun it will be to do full time Linux C/C++ coding, and reverse engineering of WORM file systems and proprietary containers and databases, the thing I am most looking forward to is quite mundane: I can do what the fuck I want!
Being stuck in a project? No problem, any of my own projects is just a 'git clone' away. (Or fetch/pull more likely... 😜)
Here I am leaving a place where gitlab.com, github.com and sourceforge.net are blocked.
But I will also miss my collegues here. I know it.
Well, part of the game I guess?7 -
Just debugged an angularjs app for 2 hours to find out that I spelled "response" "reponse" as an http get request success callback function argument. I hate my life.5
-
Yesterday, I tried to code without googling to see how far I can go. After 20 minutes of coding I run into a problem. I just couldn't make my angularjs app to work with ASP.Net MVC antiforgerytoken. I tried my best to solve it but no luck.
After 2 hours I finally gave up and connect my laptop to network and search for answer, within a few seconds. Google give my this link: http://ojdevelops.com/2016/01/....
After only few minutes I finally make my code to work. And I realized that there is no way I can figure this things out using only my head. I still need the help of community to get things done.
So my question is. During the 80's and 90's how did the old programmers get themselves unstuck when problem like this arrive?8 -
Allright, this one begs for a rant.
Me (Linux boi):
0 checkout code
1 update local config file
2 compile
3 deploy locally
4 run
5 use
Coleague (Windows boi):
0 checkout code
1 update local config file
2 compile
3 deploy locally
4 run
-1 "configuration xyz not found in config file"
→ goto #3
After 4 attempts:
ø windows.reboot()
3 deploy locally
4 run
-1 "configuration xyz not found in config file"
3 deploy locally
4 run
5 use
// out of curiosity...
3 deploy locally
4 run
-1 "configuration xyz not found in config file"
NO side actions taken (no configs updated, no code changes made, no nothing. Just simple double-clicking the redeploy script again and again)
Now... How do you objectively explain THAT?

NEW 6 Programming Language 2k16
1. Go
Golang Programming Language from Google
Let's start a list of six best new programming language and with Go or also known by the name of Golang, Go is an open source programming language and developed by three employees of Google and the launch in 2009, very cool just 3 people.
Go originated and developed from the popular programming languages such as C and Java, which offers the advantages of compact notation and aims to keep the code simple and easy to read / understand. Go language designers, Robert Griesemer, Rob Pike and Ken Thompson, revealed that the complexity of C ++ into their main motivation.
This simple programming language that we successfully completed the most tasks simply by librariesstandar luggage. Combining the speed of pemrogramandinamis languages such as Python and to handalan of C / C ++, Go be the best tools for building 'High Volume of distributed systems'.
You need to know also know, as expressed by the CTO Tokopedia namely Mas Leon, Tokopedia will switch to GO-lang as the main foundation of his system. Horrified not?
eh not watch? try deh see in the video below:
[Embedyt] http://youtube.com/watch/...]
2. Swift
Swift Programming Language from Apple
Apple launched a programming language Swift ago at WWDC 2014 as a successor to the Objective-C. Designed to be simple as it is, Swift focus on speed and security.
Furthermore, in December 2015, Swift Apple became open source under the Apache license. Since its launch, Swift won eye and the community is growing well and has become one of the programming languages 'hottest' in the world.
Learning Swift make sure you get a brighter future and provide the ability to develop applications for the iOS ecosystem Apple is so vast.

3. Rust
Rust Programming Language from Mozilla
Developed by Mozilla in 2014 and then, and in StackOverflow's 2016 survey to the developer, Rust was selected as the most preferred programming language.
Rust was developed as an alternative to C ++ for Mozilla itself, which is referred to as a programming language that focus on "performance, parallelisation, and memory safety".
Rust was created from scratch and implement a modern programming language design. Its own programming language supported very well by many developers out there and libraries.
4. Julia
Julia Programming Language
Julia programming language designed to help mathematicians and data scientist. Called "a complete high-level and dynamic programming solution for technical computing".
Julia is slowly but surely increasing in terms of users and the average growth doubles every nine months. In the future, she will be seen as one of the "most expensive skill" in the finance industry.
5. Hack
Hack Programming Language from Facebook
Hack is another programming language developed by Facebook in 2014.
Social networking giant Facebook Hack develop and gaungkan as the best of their success. Facebook even migrate the entire system developed with PHP to Hack
Facebook also released an open source version of the programming language as part of HHVM runtime platform.
6. Scala
Scala Programming Language
Scala programming termasukbahasa actually relatively long compared to other languages in our list now. While one view of this programming language is relatively difficult to learn, but from the time you invest to learn Scala will not end up sad and disappointing.
The features are so complex gives you the ability to perform better code structure and oriented performance. Based programming language OOP (Object oriented programming) and functional providing the ability to write code that is capable of evolving. Created with the goal to design a "better Java", Scala became one behasa programming that is so needed in large enterprises.3 -
Inmates are trying to take over the asylum again.
Got a message from the web team manager deeply concerned because since switching to the new logging framework, the site is significantly slower.
She provided no proof or any data to what 'significantly slower' means.
#1 The 'new logging' has been in place and logging for 5 years. We only recently depreciated the ILogger interface ('new' ILogger interface only has 1 method instead of 5)
#2 The 'old logging' was modified 5 years ago, so even if you were using the 'old' interface, the underlying implementation is still the same.
She tried to push the 'it wasn't this slow before' argument, so I decided to do some fact based analysis.
Knowing they deployed their logging changes couple of weeks ago, I opened up AppDynamics, looked at the average call time to Splunk (along with a few other http calls they are doing)
- caching services - 5ms
- splunk - 30ms
- Order Service - 350ms
- Product Data Service -525ms
Then I look at the data they are logging, for the month of June, over 5 million messages. At 30ms each, that's almost 42 hours spent logging errors...yes errors. Null reference exceptions, Argument exceptions, easily fixable stuff.
So far for the month of July (using the 'new' logging), almost 2.5 million errors. Pretty close so far with June's numbers.
My only suggestion was to fix the bugs in their code so they don't log so many errors.
Her response.."Can we have one of our developers review your logging code? We believe we can find ways to optimize the http requests"
Oh good Lord. I'm not a drinking man..but ...I might start.1 -
Gaming community of mine launched their slick new website with their new "ticket system" where people could put in tickets to get help by volunteers.
2 hours and an approval by one of the admins later I managed to inject forge http request into literally every form on that side. Modify permissions, delete users, edit tickets, put invalid values into every attribute of them... In other words break everything.
Turns out the whole thing was coded as a first time project by a person who has no clue about web development and noone is in charge of anything really. There are no requirements, no beta testing, no version control or backups, but at least they had a hard deadline. 🤣
Still not sure if I wanna fix their shit and do it properly or just enjoy seeing it crash and burn.5 -
Why is it that pretty much zero package & framework maintainers understand semantic versioning?
1. If you do a complete rewrite of your package, but the resulting API is identical, you don't need to bump to the next major version. As a user, I'm thankful for your increased performance or cleaner internal code, but it doesn't really affect my update process.
2. If your package required some-framework 6.0.0, and now ALSO supports some-framework 7.0.0 but is still compatible with 6.0.0, you don't need to bump to the next major version. As a user, I can now upgrade the framework, and know that the package will keep working, but otherwise it doesn't really affect me.
3. Following your versioning along with the framework/language version is super annoying, especially if your library really doesn't need to differentiate between framework versions because it's not actually utilizing new framework functionality.
4. On the other hand, if you stop supporting a certain language, framework or shared library version, or change the public methods, exceptions, fields, etc, you MUST bump to a new major version.
Yet everyone gets this wrong.
For example, many of Laravel's underlying subpackages (for collections, filesystem, database, config, http, mail, etc) do not change their code in a breaking way, or do not even change at all between major framework versions.
Yet they follow along with the major framework version.
Now if someone makes a library "laravel-elasticsearch" which uses the support libraries and collections from laravel, they need to update their package to move along with the versions as well, and often they choose to number their library along with the framework in turn.
This means that to update the framework, you also need to update over 9000 dependencies.
FOR NO FUCKING REASON. THE ONLY CHANGE IN THOSE FUCKING DEPENDENCIES IS TO UPDATE COMPOSER.JSON TO BE COMPATIBLE WITH THE FUCKING FRAMEWORK.
Meanwhile, Laravel itself breaks repeatedly on minor/patch version updates, because breaking changes slip through their review process.
Ugh.3 -
The company I am currently working for is partnering with another startup. Nothing special about that. We should integrate their API into our system. I wasn't involved in the process when it came to checking there API and if it would work with our Systems. The Person who did that already left the company so I was left behind with some internal documentation. In that Documentation is already written that API is basically trash....
After I started integrating the API I found more and more flaws in the design. They are not sending any responses that would help, when a param is missing or the authentication isn't correct, only 500's . I got some documentation from the partner company so i thought it will be fine as long as the Documentation would be accurate. Turns out the documentation isn't even close to be up to date. Wrong content types wrong endpoints, wrong naming. Basically we could not work with that. We shortly contacted the partner Company. After a few WEEKS we got a response that they updated the Documentation what was right but still not everything was correct. At this point I lost my mind. I researched a little bit about them, the company is founded from 2 young people who basically came strait out of the University and doest have any experience or idea how to build an API. I investigated a little bit there websites.
They have an Admin panel on the base domain from their API but it is only accessible via HTTP. Like WTF , They use HTTP for an Admin Panel this must be a joke right?
They use Cloudflare without a HTTP to HTTPS redirection ???
I really had not that much time to research in there website but if I find these things in 5 minutes I don't want to know what I can find in like an hour.
At the end we will still use them as partners because surprise surprise our company already sold the product that uses their API.
I know that I will be the person who has to help fixing this shit when it breaks and it will break 1000% JUST FUCK THIS SHIT. FUCK THE PARTNER COMPANY. FUCK THERE API.2 -

Fucking shit, this university's website is so damn slow! Basically Every Semester, every student need to enroll to certain classes in University Website.
But the Infrastructure is not enough to handle such a big amount of students, we have approx. 7000 students enrolling at the same fucking time.
And here i am can't enroll to any class at all this semester. Fuck such a waste of time. This always been a thing since they digitalize enrolling system.
I don't want this to happen again. The student always be a victim since they cannot handle the request. Now, as a dev, i want to propose something better to optimize the server, i have some connection to pass some bureaucracy. I am going to do some brainstorming and I will need some solution.
Here some data i gather when i am mad from my univ infrastructure division :
1. The Server is a simple Local Server Forwarded to the Internet.
2. The Server use Windows Server 2007.
4. Web Server Using Microsoft IIS
3. The Website built using ASP.NET
4. The connection is not SSL encrypted (yes its fucking use the http)
5. Hardware Spec (not confirmed officialy, i got this information from my professor) :
- Core i5 4460
- 4 GB Ram
- 1 Gbit NIC
I will summon some expert here and i hope want to help me(us all) out.24 -
So I have to fix this motherfucking insane regex with over 1k chars in it ...
This fucking shit is not maintainable and there are no comments or any other sort of documentation.
And this bullshit was not build via code so that bastard wasted weeks of time to develop that shitty expression by hand on a online regex tester website.
So I have 3 options:
1. Reverse engineer everything and waste my precious time
2. Delete that shit, analyze the input and write the regex via code instead of creating it by hand
3. Look for that "super duper clever" dev and break his legs.
I think option 3 suits me best.
And for you dear reader, if you are regexphile, enjoy this gigantc regex with >16k chars:

Apart from having a baby which is the hardest in the world,i think the hardest project is to learn to code.
I studied philosophy and anthropology but gamed a lot. Me and a good mate decided to work together and he told me hed teach me coding.
The guy is a genius but he is a reckless rebel genius who tells everybody to fuck off.
So,after 1 year in a half of intense coding where i had to learn linux, networks, and im not shitting you html and css as well and of course javascript.
He has now put me on, for the last 2 month, in charge of our front end backoffice. I have to design forms that do the right http requests,do the unit testing, play with redux-form, react-redux and he has thrown me into the basic java backend so i can begin working with entites and how i serve the data and link it to the database and even create tables.
Every time i fail hemakes me remake everything.
I actually came on devrant to study the dev community (i always gamed a lot but this is a whole different community). The dev community is pretty awesome and unique.
Anyhow, i remember when i saw him as me to complete an exercise and i didnt event know which words were the reserved language ones and those i could use myself. It was like fucking magic.3 -
"There's more to it"
This is something that has been bugging me for a long time now, so <rant>.
Yesterday in one of my chats in Telegram I had a question from someone wanting to make their laptop completely bulletproof privacy respecting, yada yada.. down to the MAC address being randomized. Now I am a networking guy.. or at least I like to think I am.
So I told him, routers must block any MAC addresses from leaking out. So the MAC address is only relevant inside of the network you're in. IPv6 changes this and there is network discovery involved with fandroids and cryphones where WiFi remains turned on as you leave the house (price of convenience amirite?) - but I'll get back to that later.
Now for a laptop MAC address randomization isn't exactly relevant yet I'd say.. at least in something other than Windows where your privacy is right out the window anyway. MAC randomization while Nadella does the whole assfuck, sign me up! /s
So let's assume Linux. No MAC randomization, not necessary, privacy respecting nonetheless. MAC addresses do not leak outside of the network in traditional IPv4 networking. So what would you be worried about inside the network? A hacker inside Starbucks? This is the question I asked him, and argued that if you don't trust the network (and with a public hotspot I personally don't) you shouldn't connect to it in the first place. And since I recall MAC randomization being discussed on the ISC's dhcp-users mailing list a few months ago (http://isc-dhcp-users.2343191.n4.nabble.com/...), I linked that in as well. These are the hardcore networking guys, on the forum of one of the granddaddies of the internet. They make BIND which pretty much everyone uses. It's the de facto standard DNS server out there.
The reply to all of this was simply to the "don't connect to it if you don't trust it" - I guess that's all the privacy nut could argue with. And here we get to the topic of this rant. The almighty rebuttal "there's more to it than that!1! HTTPS doesn't require trust anymore!1!"
... An encrypted connection to a website meaning that you could connect to just about any hostile network. Are you fucking retarded? Ever heard of SSL stripping? Yeah HSTS solves that but only a handful of websites use it and it doesn't scale up properly, since it's pretty much a hardcoded list in web browsers. And you know what? Yes "there's more to it"! There's more to networking than just web browsing. There's 65 THOUSAND ports available on both TCP and UDP, and there you go narrow your understanding of networking to just 2 of them - 80 and 443. Yes there's a lot more to it. But not exactly the kind of thing you're arguing about.
Enjoy your cheap-ass Xiaomeme phone where the "phone" part means phoning home to China, and raging about the Google apps on there. Then try to solve problems that aren't actually problems and pretty vital network components, just because it's an identifier.
</rant>
P.S. I do care a lot about privacy. My web and mail servers for example do not know where my visitors are coming from. All they see is some reverse proxies that they think is the whole internet. So yes I care about my own and others' privacy. But you know.. I'm old-fashioned. I like to solve problems with actual solutions.11 -
So here I am reinventing the wheel making an HTTP server in C.
Finished implementing HTTP/1.1 and WebSockets support and now I find out the current thingy is HTTP/2.
Well that's fine, I'll add support for that later. In fact I kinda dig it since it uses binary conventions instead of plain text ones.
I dig a little bit and find out there already is an HTTP/3 going around which uses UDP.
Why me.5 -
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?!?????4 -

Dear fellow developers: Let's talk about the Internet. If you're reading this post, you've probably heard of it and are comfortable using it on a regular basis. You may even develop software that works over the internet, and that's fine and great! But you have to draw the line somewhere, and that line has been pushed farther and farther back as time goes on.
Let's talk about video games. The first game that really got me into FPSes was Team Fortress 2. Back in the day, it had a great community of casual and competitive groups alike, and there were hats! Underneath the hood was a massive number of servers. Some were officially hosted, some were run by independent communities. It had a built-in browser and central index where you could find every publically-available server and connect to it. You could even manually input connection details if that failed. In my opinion, this was a near-perfect combination of optimal user-experience and maximum freedom to run whatever the hell you wanted to. Even today, if Valve decided to stop hosting official servers, the smaller communities could still stay afloat. Fifteen years in the future, after all demand has died off, someone can still recover the server software and play a game with their kids.
Now, contrast that to a game like Overwatch. Also a very pivotal game in the FPS world, and much more modern, but what's the underlying difference in implementation? NO SUPPORT FOR SELF-HOSTED SERVERS. What does that mean when Blizzard decides to stop hosting its central servers? IT DIES. There will be no more multiplayer experience, not now, not ever. You will never be able to fully share this part of your history with future generations.
Another great example is the evolution of voice chat software. While I will agree that Discord revolutionized the market, it took away our freedom to run our own server on our own hardware. I used to run a Mumble server, now it has fallen out of use and I miss it so much.
Over time, client software has become more and more dependent on centrally-hosted services. Not many people will think about how this will impact the future usability of the product, and this will kill our code when it becomes legacy and the company decides to stop supporting it. We will have nothing to give to future generations; nobody will be able to run it in an emulator and fully re-experience it like we can do with older games and software.
This is one of the worst regressions of our time. Think about services like IRC, SMTP, SSH, even HTTP, how you're so easily able to connect to any server running those protocols and how the Internet would change if those were replaced with proprietary software that depended on a central service.
(Relevant talk (16:42): https://youtu.be/_e6BKJPnb5o?t=1002)6 -
So here's is the thing.
For some weird reason I decided to work at a VC funded startup. For 15k year,(I live in a really poor country).
So, let me describe the hell I'm in now, and if for some good grace you happen to be hiring, please consider saving me from the horror that's ahead.
Company got funded 5 months ago, main owners are, an economist and a civil engineer with no programming habilities whatsoever.
They took 1 month to assemble "a killer team", with no hiring expertise they handpicked a CTO that came in 1 month later and took a month of vacation in his first month of work.
He didn't do any specification of the system that needs to be built.
The 2 naive owners hired the rest of this "killer team".
The team is good, but have no appreciation of planning.
They've built and rebuilt the backend system twice, once in graphql and the second with plain http (is not real rest, just a http api), in front of, guess what a mongo database.
This mongo DB is not only one, but 7, because we have 7 microservices, and each has its own database.
After some time, they decided to fire their CTO, and hire one more programmer(that's me), because the CTO wasn't doing anything.
The app has 3 parts, the app per se, a business version, and a help desk, guess what the helpdesk just appeared last week on the radar.
Long story short, we have one month to deliver what couldn't be built in 5.
When I decided to work for these people, I did not imagine the kind of clusterfuck that I was getting into.
It took me 1 month to realize the whole situation, now, I really would like to see some help from the deities of any religion, not for the project, that project is doomed.
It's how I'll pay the bills after that clusterfuck collapses that worries me.
Now in the startup no one is talking about how stupid the whole situation is. Or how far back we are. And at this point there's very little that could be done about it, I have a feeling that it could still be accomplished, but it's fading day after day.
I will do my best to live the best of this experience, and do as the musicians in the Titanic and keep playing the music even after knowing the Titanic is sinking.4 -
Http/2 server push is really cool. Like, really fucking cool. Those researchers at google really got this right. I hate how they handle their users but I have to say they really make good use of the money they get by selling us for kettle.2

Just started using the Dropbox API. Want to do a simple directory listing of my files. Sends HTTP GET request at https://api.dropboxapi.com/2/files/....
"Error in call to API function "files/list_folder": Your request's HTTP request method is "GET". This function only accepts the HTTP request method "POST"."
What. The. Fuck. Dropbox.
HTTP POST is for creating a new instance of a resource. HTTP GET is for reading. GET guarantees server state is not changed while POST does not. I want to fucking list a directory, not put stuff in it.1 -
Crazy... Hm, that could qualify for a *lot*.
Craziest. Probably misusage or rather "brain damaged" knowledge about HTTP.
I've seen a lot of wild things when devs start poking standards, but the tip of the iceberg was someone trying to use UTF-8 in headers...
You might have guessed it - German umlauts. :(
Coz yeah. Fucktard loved writing everything in german, so why not write custom header names in german.
The fun thing is: It *can* work, though the usual sane thing is to keep it in ASCII range for the obvious reason that using UTF-8 (or ISO-8859-1, which is *not* ASCII) is a gamble you gonna loose.
The fun game was that after putting in a much needed load balancer between services for monitoring / scaling etc suddenly *something* seemed off.
It took me 2 days and a lot of Wireshark hoola hooping to find out why, cause the header was used for device detection aka wether it's a bot or not. Or in the german term the dev used: "Geräte-Art".
As the fallback was to assume a bot, but only rate limit based on IP, only few managed to achieve the necessary rate limit to get blocked.
So when I say *something* seemed off, I really mean a spooky kind of "sometimes IP blocked for seemingly no reason at all".
Fun stuff. The dev btw germanized everything. Untangling the code base was a lot of non fun. -.-6 -
I don't know what you did yesterday, but i did make my company throw away 2 months of progress.
It all started in the beginning, since that i've made numerous complaints about the workflow or code and how to improve it. I've been told off every time, and every time i either told the boss who agreed in the end or wrote code to prove myself. Everything was a hassle and my tasks weren't better.
Team lead: you'll do X now, please do that by making Y.
Me: but Y is insecure, we should do Z.
Team lead: please do Y
Later it turns out Y is impossible and we do Z in the end...
Team lead: please do W now
Me, a few days later: i've tried and their server doesn't give http cors headers, doing W in the browser is impossible
Team lead, a few days later: have you made progress on W?
Me: * tells again it's impossible and uploads code to prove it *
Team lead: * no response *
After that i had enough. Technically i still was assigned to do W, but i used my time to look over the application and list all the things wrong with it. We had everything, giant commits, commented out code, unnecessary packages, a new commit introduced packages that crashed npm install on non-macs, angularjs-packages even though we use angular, weird logic, a security bug, all css in one file even though you can use component-specific css files...
I sent that to my boss, telling him to let the backend-guys have a look at it too and we had a meeting about this. I couldn't attend but they agreed with me completely. They decided to throw away what we have already and to let one of the backend-guys supervise our team. I guess there will be another talk with the team lead, but time will tell.
It feels so good having hope to finally escape this hellish development cycle of badly defined task, bad communication and headache-inducing merges. -
Strap in...
- Previous employer
- 3rd party partner firm
- integration link between both over SOAP
- Both sides riddled with poor code and messed up political structures (partner firm CEO is an investor in my employer)
- Doing a deployment to update to https (I know)
- Keep http endpoint live
- Other side starts shitting itself
- Diagnose
- Not us
- feelsgoodman.tiff
- Get angry email
- Explain not us
- Back and forth
- Tell client it’s “irrelevant” on https issue, it’s their side that’s gone wrong
- Get angry reply with boss cc’d about how nothing is “irrelevant” for the client
- We all had to have a make up meeting and meal
- Client was calm and reasonable, all agreed we just snapped and it wouldn’t happen again
- 2 weeks later
- Their system shits itself again and suddenly we’re on the hook
- BA on my team (smarmy little bastard) constantly fucking me off
- Get so close to actually screaming and hitting him
So yeah. I don’t tend to hold that a job is more important to me than my dignity.
I have and will never hold my tongue for the sake of a job, I’m not gonna put up with people shouting / belittling / backstabbing etc. -
In today's episode of kidding on SystemD, we have a surprise guest star appearance - Apache Foundation HTTPD server, or as we in the Debian ecosystem call it, the Apache webserver!
So, imagine a situation like this - Its friday afternoon, you have just migrated a bunch of web domains under a new, up to date, system. Everything works just fine, until... You try to generate SSL certificates from Lets Encrypt.
Such a mundane task, done more than a thousand times already... Yet... No matter what you do, nothing works. Apache just returns a HTTP status code 403 - Forbidden.
Of course, what many folk would think of first when it came to a 403 error is - Ooooh, a permission issue somewhere in the directory structure!
So you check it... And re-check it to make sure... And even switch over to the user the webserver runs under, yet... You can access the challenge just fine, what the hell!
So you go deeper... And enable the most verbose level of logging apache is capable of - Trace8. That tells you... Not a whole lot more... Apparently, the webserver was unable to find file specified? But... Its right there, you can see it!
So you go another step deeper and start tracing the process' system calls to see exactly where it calls stat/lstat on the file, and you see that it... Calls lstat and... It... Returns -1? What the hell#2!
So, you compile a custom binary that calls lstat on the first argument given and prints out everything it returns... And... It works fine!
Until now, I chose to omit one important detail that might have given away the issue to the more knowledgeable right away. Our webservers have the URL /.well-known/acme-challenge/, used for ACME challenges, aliased somewhere else on the filesystem - To /tmp/challenges.
See the issue already?
Some *bleep* over at the Debian Package Maintainer group decided that Apache could save very sensitive data into /tmp, so, it would be for the best if they changed something that worked for decades, and enabled a SystemD service unit option "PrivateTmp" for the webserver, by default.
What it does is that, anytime a process started with this option enabled writes to /tmp/*, the call gets hijacked or something, and actually makes the write to a private /tmp/something/tmp/ directory, where something... Appeared as a completely random name, with the "apache2.service" glued at the end.
That was also the only reason why I managed fix this issue - On the umpteenth time of checking the directory structure, I noticed a "systemd-private-foobarbas-apache2.service-cookie42" directory there... That contained nothing but a "tmp" directory with 777 as its permission, owned by the process' user and group.
Overriding that unit file option finally fixed the issue completely.
I have just one question - Why? Why change something that worked for decades? I understand that, in case you save something into /tmp, it may be read by 3rd parties or programs, but I am of the opinion that, if you did that, its only and only your fault if you wrote sensitive data into the temporary directory.
And as far as I am aware, by default, Apache does not actually write anything even remotely sensitive into /tmp, so...
Why. WHY!
I wasted 4 hours of my life debugging this! Only to find out its just another SystemD-enabled "feature" now!
And as much as I love kidding on SystemD, this time, I see it more as a fault of the package maintainers, because... I found no default apache2/httpd service file in the apache repo mirror... So...8 -
I actually never felt the need to scream at a co-worker so let's talk about that time a co-worker screamed at me instead.
tl;dr : some asshole boss screamed and threatened me because someone else's project was shit and didn't work.
Context: I was in my third year of school internship (graded) and my experience is C, C++, C#, Python all in systems programming, no web.
I was working as an intern for a shit company that was selling a shit software to hospitals (though not medically critical, thank God) the only tech guy on site was the DBA (cool guy) the product was maintained by a single dev in VB from his house, the dude never showed up to work (you'll understand why) and an other intern who couldn't dev shit.
I was working with the DBA on an software making statistical analysis from DB exports, worked nice, no problems here if we forget the lack of specs or boundaries (except must work in ieShit).
The other intern was working on something else (don't ask me what it is) I just remember it was in GWT before the community revived it. His webapp was requesting the company http server for a file instead of having one of it's java servlet to fetch it (both apps ran on sane server) which caused a lot of shit especially CORS error. That guy left (end of contract) and leaves his shit as is, boss asked me to deploy the app, I fiddle with it to see if it works and when I find out it doesn't then that asshole starts screaming at me in front of every other employee present, starts threatening to burn me in the tech world and have me thrown out of my school for no goddamn reason than the other dude's project doesn't work.
After the screaming I leave and warn my school immediately.
I guess that's why the other dev never came to work.
I had three weeks of internship left, that I did from home and worked probably less than 2 hours a day so suck it asshole.
Still had a good grade because I was reviewed by the DBA and he was happy with the work I did.
It was only later that I realized that what he did was categorizing as harassment (at least in France) and decided that never again this would happen without a response from my lawyer.1 -
I explained last week in great detail to a new team member of a dev team (yeah hire or fire part 2) why it is an extremely bad idea to do proactive error handling somewhere down in the stack...
Example
Controller -> Business/Application Logic -> Infrastructure Layer
(shortened)
Now in the infrastructure layer we have a cache that caches an http rest call to another service.
One should not implement retry or some other proactive error handling down in the cache / infra stack, instead propagate the error to the upper layer(s) like application / business logic.
Let them decide what's the course of action, so ...
1) no error is swallowed
2) no unintended side effects like latency spikes / hickups due to retries or similar techniques happens
3) one can actually understand what the services do - behaviour should either be configured explicitly or passed down as a programmed choice from the upper layer... Not randomly implemented in some services.
The explanation was long and I thought ... Well let's call the recruit like the Gremlin he is... Gizmo got the message.
Today Gizmo presented a new solution.
The solution was to log and swallow all exceptions and just return null everywhere.
Yay... Gizmo. You won the Oscar for bad choices TM.
Thx for not asking whether that brain fart made any sense and wasting 5 days with implementing the worst of it all.6 -
Sorry, need to vent.
In my current project I'm using two main libraries [slack client and k8s client], both official. And they both suck!
Okay, okay, their code doesn't really suck [apart from k8s severely violating Liskov's principle!]. The sucky part is not really their fault. It's the commonly used 3rd-party library that's fucked up.
Okhttp3
yeah yeah, here come all the booos. Let them all out.
1. In websockets it hard-caps frame size to 16mb w/o an ability to change it. So.. Forget about unchunked file transfers there... What's even worse - they close the websocket if the frame size exceeds that limit. Yep, instead of failing to send it kills the conn.
2. In websockets they are writing data completely async. Without any control handles.. No clue when the write starts, completes or fails. No callbacks, no promises, no nothing other feedback
3. In http requests they are splitting my request into multiple buffers. This fucks up the slack cluent, as I cannot post messages over 4050 chars in size . Thanks to the okhttp these long texts get split into multiple messages. Which effectively fucks up formatting [bold, italic, codeblocks, links,...], as the formatted blocks get torn apart. [didn't investigate this deeper: it's friday evening and it's kotlin, not java, so I saved myself from the trouble of parsing yet unknown syntax]
yes, okhttp is probably a good library for the most of it. Yes, people like it, but hell, these corner cases and weird design decisions drive me mad!
And it's not like I could swap it with anynother lib.. I don't depend on it -- other libs I need do! -

Java Server Faces!
Don't get me wrong, I kinda love coding Java, but JSF is just a horrible technique for web development.
Had to do it since my company got to maintain an already existing backend which the customer wanted to have some more Features but the original dev didnt continue to support.

So client wants an android app that implements some legacy Epson printer SDK, works on a chinese Windows device with an android Emulator on it, connects to local Webservice that had to be configurated and ran (local Network) , sends and tracks data, if Server down then handle it on the Client and reconnect as soon as Server up, running own TCP Server on Android device that listens for specific http requests, which make the android connect to an Epson printer to start printing. The stuff that is being printed? A png file that has to be converted to a Bitmap, a QR Code that has to be generated by the bugged base64 encrypted stuff coming via http in (webserver-> Android TCP server)
Dont forget the Software Design (MVP), documentation, research etc.. Im about to finish the app , its my 5th day on this Project, the 6th day was planned to be full testing. Client Calls me and ask me how far I am, I reply, he says ok. 30 minutes later he tells me he wont pay me next time that much because this work should take 3 days, or even 2. "A senior Android developer could do this in 2 days"... When i sent him my notices he called me a liar, his webdev has alot of experience and told him it should take 2-3 days...ffs2 -
to;dr: school, raspi, spoofing, public status screen, funny pictured.
So. At school we had these huge ass 2/3 TVs displaying some information such as which teacher is ill, which lessons won't take place and some school related news. Standard stuff.
They worked using a raspberry pi attached to the TV fetching a website over http every now and then.
Using nmap I discovered that these pi's were in the same network as the pupils devices: Sweeeet.
After trying some standard passwords at the ssh port and not succeeding I came up with something different: A spoofing attack.
I would relay all traffic from those pi's through my device, would replace all images with a trollface picture (I know I know) and flip all text upside down.
Chaos, annoyed faces and laughter.
It was beautiful. -
Good morning to everyone, except that one Twitter dev who one day woke up and was like "YOU KNOW WHAT, MY APPLICATION WILL FEATURE BOTH OAUTH1 AND OAUTH2 ENDPOINTS, BUT SOME FEATURES WILL BE EXCLUSIVE TO EITHER OF THE TWO -NOT NECESSARILY THE MOST RECENT, JUST A RANDOM ONE-, AND ALSO THE OFFICIAL TWITTER LIBRARY WON'T COVER ALL THE ENDPOINTS SO PEOPLE WILL HAVE TO RESORT TO RAW HTTP REQUESTS INSTEAD OF USING MY SDK AND ALSO I'MMA MAKE DEVELOPERS FILL 2 VERY DETAILED FORMS, REQUIRING PERSONAL DATA AND ACTUAL REAL PHONE CALLS, JUST TO START DEVELOPMENT WITH 7 DIFFERENT AUTHENTICATION TOKENS, BECAUSE SOME REQUESTS WILL REQUIRE A DIFFERENT AUTHENTICATION METHOD THAN THE OTHER REQUESTS DESPITE ALL OF THEM PERTAINING TO THE SAME FUCKING ENTITY"3
-
GWT.
Let me explain:
Tl;dr : someone fucked up, I took shit, it was a gwt project. In a sense I don't hate GWT because of the framework itself but because how I was introduced and forced to "work" with it.
Context:
Was working as a paid intern at a small company there were 3 devs 2 interns and one senior employee that only worked from home handling the shit ton of legacy VB6 code he wrote over several year and a boss with no technical knowledge. (Other unimportant people as well)
I was working with their DBA (cool dude) because I was writing statistic and report generating software.
Story:
The other intern was tasked of doing a gwt app that was supposed to use a input file.
Rather than asking the user to upload it with a file picker (I guess they exist in gwt I didn't got to dig in the framework) he was trying to load the file with a http request directed at the same host the app was running on.
It did not work.
Then his contract was other and the app was left in an unfinished state.
The boss then tried to have the app deployed, the remaining dev dodged the bullet invoking some bullshit because he was clearly incapable of doing it.
So it fell on me, couldn't deploy the app because it was not even close to working.
Tried to fix things and make it work.
Turns out he thought it would take me 3h to deploy when I clearly explained that the other guy didn't finish the app.
Boss got mad, threatened to ruin my studies and my future career.
Couldn't because my uni had my back.
Didn't want to see me anymore.
Couldn't break my contract.
Told me to work from home for the end of my internship.
I got 3 weeks early vacation and got paid, fuck him, fuck GWT, fuck his company.
Still got well marked for the internship as my supervisor was the DBA who was happy with my work.

Don't let your intern unsupervised, don't let your main dev work from home when you don't know shit, don't piss me off and send me work from home. -
Very eventful day, please see enclosed several smaller rants.
===================
My college's systems are shit and not only do they use HTTP for everything, even the stores and financial aid purchase system, they have homebrew JS shit for PGP site encryption (nifty...), but they exchange the PRIVATE KEYS instead of the public keys. Over HTTP. Not even HTTPS. Also if you log in more than 10 times in 24 hours it's supposed to lock you out of your account until you call... except it locks EVERYONE out. Found this out when on campus, trying to get my textbooks, when suddenly everyone had login lockouts because i'm a "paranoid bastard" and "afraid of idiot college students" for not telling a PUBLIC PC to remember the one password (enforced by password auto-sync across all their shit, not ideal, no) guarding my SUPER-SENSITIVE FINANCIAL AND ACADEMIC DATA... among the other hundreds of issues this college has. I now see why this college is the only one I can afford...
===================
Can't pass-through raw DVD drive access to VMs as VM managers crash when I try (yes, even QEMU...) so i've gotta install Windows on a shitty 80GB laptop HDD for literally one quick project. On the bright side, if my theory proves correct, you'll no longer need modchips for PS2s.
===================
Found a couple odd lines in my xscreensaver config:
GetViewPortIsFullOfLies:False
nice: 10
pointerHysteresis: 10
the first 2 I can't seem to figure out what do, and the last taught me a new word. Fun!
===================
that's it, it's over, why are you still here11 -
Am I the only developer in existence who's ever dealt with Git on Windows? What a colossal train wreck.
1. Authentication. Since there is no ssh key/git url support on Windows, you have to retype your git credentials Every Stinking Time you push. I thought Git Credential Manager was supposed to save your credentials? And this was impossible over SSH (see below). The previous developer had used an http git URL with his username and password baked in for authentication. I thought that was a horrific idea so I eventually figured out how to use a Bitbucket App password.
2. Permissions errors
In order to commit and push updates, I have to run Git for Windows as Administrator.
3. No SSH for easy git access
Here's where I confess that this is a Windows Server machine running as some form of production. Please don't slaughter me! I am not the server admin.
So, I convinced the server guy to find and install some sort of ssh service for Windows just for the off times we have to make a hot fix in production. (Don't ask, but more common than it should be.)
Sadly, this ssh access is totally useless as the git colors are all messed up, the line wrap length and window size are just weird (seems about 60 characters wide by 25 lines tall) and worse of all I can't commit/push in git via ssh because Permissions. Extremely aggravating.
4. Git on Windows hangs open and locks the index file
Finally, we manage to have Git for Windows hang quite frequently and lock the git index file, meaning that we can't do anything in git (commit, push, pull) without manually quitting these processes from task manager, then browsing to the directory and deleting the .git/index.lock file.
Putting this all together, here's the process for a pull on this production server:
Launch a VNC session to the server. Close multiple popups from different services. Ask Windows to please not "restart to install updates". Launch git for Windows. Run a git pull. If the commits to be pulled involve deleting files, the pull will fail with a permissions error. Realize you forgot to launch as Administrator. Depending on how many files were deleted in the last update, you may need to quit the application and force close the process rather than answer "n" for every "would you like to try again?" file. Relaunch Git as Administrator. Run Git pull. Finally everything works.
At this point, I'd be grateful for any tips, appreciate any sympathy, and understand any hatred. Windows Server is bad. Git on Windows is bad.10 -
IT CAN'T BE THAT HARD
1) A CONTROLLER RETURNS HTTP RESPONSES, computed using data received from
2) A SERVICE\MANAGER\YOURMOTHER, which fetches data from a DB\external service\whatever
LITERALLY 2 FUCKING STEPS. I'LL TAKE THAT "SENIOR" IN YOUR TITLE AND CHISEL IT ON YOUR FOREHEAD SO YOU'LL REMEMBER WHAT YOU'RE SUPPOSED TO BE WHEN YOU COMMIT THIS FUCKING GARBAGE2 -
SO MAD. Hands are shaking after dealing with this awful API for too long. I just sent this to a contact at JP Morgan Chase.
-------------------
Hello [X],
1. I'm having absolutely no luck logging in to this account to check the Order Abstraction service settings. I was able to log in once earlier this morning, but ever since I've received this frustratingly vague "We are currently unable to complete your request" error message (attached). I even switched IP's via a VPN, and was able to get as far as entering the below Identification Code until I got the same message. Has this account been blocked? Password incorrect? What's the issue?
2. I've been researching the Order Abstraction API for hours as well, attempting to defuddle this gem of an API call response:
error=1&message=Authentication+failure....processing+stopped
NOWHERE in the documentation (last updated 14 months ago) is there any reference to this^^ error or any sort of standardized error-handling description whatsoever - unless you count the detailed error codes outlined for the Hosted Payment responses, which this Order Abstraction service completely ignores. Finally, the HTTP response status code from the Abstraction API is "200 OK", signaling that everything is fine and dandy, which is incorrect. The error message indicates there should be a 400-level status code response, such as 401 Unauthorized, 403 Forbidden or at least 400 Bad Request.
Frankly, I am extremely frustrated and tired of working with poorly documented, poorly designed and poorly maintained developer services which fail to follow basic methodology standardized decades ago. Error messages should be clear and descriptive, including HTTP status codes and a parseable response - preferably JSON or XML.
-----
This whole piece of garbage is junk. If you're big enough to own a bank, you're big enough to provide useful error messages to the developers kind enough to attempt to work with you.2 -
So an app I use for real-time train schedules broke last week and the official app is really slow, UI is bloated/bad devs.
I figured out the HTTP calls so started writing my own, spent 2 days and basic functionality works but...
Now the other app is working again...
Feels like wasted effort now :(2 -
I used to be a sysadmin and to some extent I still am. But I absolutely fucking hated the software I had to work with, despite server software having a focus on stability and rigid testing instead of new features *cough* bugs.
After ranting about the "do I really have to do everything myself?!" for long enough, I went ahead and did it. Problem is, the list of stuff to do is years upon years long. Off the top of my head, there's this Android application called DAVx5. It's a CalDAV / CardDAV client. Both of those are extensions to WebDAV which in turn is an extension of HTTP. Should be simple enough. Should be! I paid for that godforsaken piece of software, but don't you dare to delete a calendar entry. Don't you dare to update it in one place and expect it to push that change to another device. And despite "server errors" (the client is fucked, face it you piece of trash app!), just keep on trying, trying and trying some more. Error handling be damned! Notifications be damned! One week that piece of shit lasted for, on 2 Android phones. The Radicale server, that's still running. Both phones however are now out of sync and both of them are complaining about "400 I fucked up my request".
Now that is just a simple example. CalDAV and CardDAV are not complicated protocols. In fact you'd be surprised how easy most protocols are. SMTP email? That's 4 commands and spammers still fuck it up. HTTP GET? That's just 1 command. You may have to do it a few times over to request all the JavaScript shit, but still. None of this is hard. Why do people still keep fucking it up? Is reading a fucking RFC when you're implementing a goddamn protocol so damn hard? Correctness be damned, just like the memory? If you're one of those people, kill yourself.
So yeah. I started writing my own implementations out of pure spite. Because I hated the industry so fucking much. And surprisingly, my software does tend to be lightweight and usually reasonably stable. I wonder why! Maybe it's because I care. Maybe people should care more often about their trade, rather than those filthy 6 figures. There's a reason why you're being paid that much. Writing a steaming pile of dogshit shouldn't be one of them.6 -
Finally upgraded my webserver and php modules to support HTTP/2 ^^ Everything works fine.
Found out devrant.com doesn't support it though. @dfox8 -

Did you know that North Korea has its own government approved Linux distro? Well, now you do.
It is so funny that the damn North Korea has fully transferred to Linux, but not any country in Europe, nor the US.
So have anyone here tried it? If so, how is it?

tldr: my classmates suck and I hate them
We study cs in school, and my classmates are super dumb.
Here is an example from today:
The task: build an http server in python, using sockets.
My classmates: writes everything in the main function, uses try-expect for everything and every error possible, nothing works, nothing worked after a week.
Me: properly separated to different functions, used goddam regrx to get data from requests, used asyncio to make sure it can handle multiple requests at the same time, everything worked after 2 hours.
But, and here is the problem, after I finish they ask me a bunch of dumb, 'Just Google it dude' questions and they call me condescending because I get mad after the second hour of teaching them the same thing.
Once they told me:"you think you are a better programmer then us" and I just want to say this out loud: I AM A BETTER PROGRAMMER THEN THEM, THEY ARE THE PERFECT EXAMPLE OF HOW YOU SHOULDN'T DO ANYTHING AND I HATE THEM.
That's it, I'm done. I feel much better now.
PS: it's okay to suck at programming, but please stop thinking that everyone who's better than you is condescending.4 -
*laughing maniacally*
Okidoky you lil fucker where you've been hiding...
*streaming tcpdump via SSH to other box, feeding tshark with input filters*
Finally finding a request with an ominous dissector warning about headers...
Not finding anything with silversearcher / ag in the project...
*getting even more pissed causr I've been looking for lil fucker since 2 days*
*generating possible splits of the header name, piping to silversearcher*
*I/O looks like clusterfuck*
Common, it are just dozen gigabytes of text, don't choke just because you have to suck on all the sucking projects this company owns... Don't drown now, lil bukkake princess.
*half an hour later*
Oh... Interesting. Bukkake princess survived and even spilled the tea.
Someone was trying to be overly "eager" to avoid magic numbers...
They concatenated a header name out of several const vars which stem from a static class with like... 300? 400? vars of which I can make no fucking sense at all.
Class literally looks like the most braindamaged thing one could imagine.
And yes... Coming back to the network error I'm debugging since 2 days as it is occuring at erratic intervals and noone knew of course why...
One of the devs changed the const value of one of the variables to have UTF 8 characters. For "cleaner meaning".
Sometimes I just want to electrocute people ...
The reason this didn't pop up all the time was because the test system triggered one call with the header - whenever said dev pushed changes...
And yeah. Test failures can be ignored.
Why bother? Just continue meddling in shit.
I'm glad for the dev that I'm in home office... :@
TLDR: Dev changed const value without thinking, ignoring test failures and I had the fun of debunking for 2 days a mysterious HAProxy failure due to HTTP header validation... -
With a recent HAProxy update on our reverse proxy VM I decided to enable http/2, disable TLS 1.0 and drop support for non forward-secrecy ciphers.
Tested our sites in Chrome and Firefox, all was well, went to bed.
Next morning a medium-critical havock went loose. Our ERP system couldn't create tickets in our ticket system anymore, the ticket systems Outlook AddIn refused to connect, the mobile app we use to access our anti-spam appliance wouldn't connect although our internal blackboard app still connected over the same load balancer without any issues.
So i declared a 10min maintenance window and disabled HTTP/2, thinking that this was the culprit.
Nope. No dice.
Okay, i thought, enable TLS 1.0 again.
Suddenly the ticket system related stuff starts to work again.
So since both the ERP system and the AddIn run on .NET i dug through the .NET documentation and found out that for some fucking reason even in the newest .NET framework version (4.7.2) you have to explicitly enable TLS 1.1 and 1.2 or else you just get a 'socket reset' error. Why the fuck?!
Okay, now that i had the ticket system out of the way i enabled HTTP/2 and verified that everything still works.
It did, nice.
The anti-spam appliance app still did not work however, so i enabled one non-pfs cipher in the OpenSSL config and tested the app.
Behold, it worked.
I'm currently creating a ticket with them asking politely why the fuck their app has pfs-ciphers disabled.
And I thought disabling DEPRECEATED tech wouldn't be an issue... Wrong... -
So I just spent 2 hours debugging a script that fetches data from an API. Thats all it was supposed to do. Http get some data.
It wasnt working and was giving a "parse error". Worked fine in browser.
So it turns out it was using http 0.9 (first documented http version, defined in 1991) and wasnt sending any headers. And js cant do no headers...
So yea I now have to write a tcp / http 0.9 client in js10 -
I think I used to identify myself heavily by my work, career and so felt very dissatisfied I wasn't living up to my potential and getting the chances I deserved. I just couldn't get my dream job...
But now it feels like I've sorta split into Work and Life. Work does whatever is needed to pay the bills and is pretty satisfied now. Still gotta deal with monkeys but maybe devRant has helped provide an outlet to unleash the stress... and maybe sorta made it fun...
But Life juggles among different things, some time wasters, but seems now not so coding heavy anymore unless it's really inspired. And doesn't like putting aside time to prepare for interviews anymore or even actively seek out the latest tech news...
I sorta forgot what I was saying but does anyone else feel they used to have one identity but now split into 2 or more?
Actually I think this is what triggered it. Read this awhile ago but suddenly had this thought in my mind...

I built my first web server literally from scratch (standard socket lib) today! In Python <3.
It is able to execute php and get the stdout to use it in the Python script afterwards and make use of parallel connections.
Now to the real rant...
I am using HTTP/1.1. I want to use h2 (aka HTTP/2) tho. I am stuck on this. Found the papers to the specs of the h2 and spdy protocols, but they are not really helpful.
Is anyone good in this field? Please let me know :/3 -
I started building an application for FIDAL (Italian Federation of Athletics) because why not: I was bored and wanted to learn Flutter.
There is no API, but I didn't even expect it. Parsing the HTML is easy enough.
BUT OH MY GOD THE ENTIRE WEBSITE IS SHIT. Take this page: http://www.fidal.it/graduatorie.php, it uses some useless jQuery plugin and uses a buttload of JavaScript that isn't even needed. BUT WAIT. Try entering an invalid "club code" (http://fidal.it/graduatorie.php/...), a FUCKING white page with 200, are you kidding?
I'd also like to mention that all pages that require form input won't load correctly if you don't include "submit=Invia" in the URL.
I am not giving up.3 -
My Top 10 most useless keys (#1 is worst):
1. Stop (the media key).
2. Pause/Break. (I understand this has historical usage, but I personaly have never used it.)
3. Page Up
4. Page Down
5. Scroll Lock
6. All those little shortcut keys along the top (above the F-keys) which open things like IE, My Documents, email etc.
7. All the modifier combinations of back tick (it in itself is useful, but WTF is a split pipe supposed to mean!? Or a ¬ !?)
8. Right Windows key.
9. Insert. Again, it has historical significance, but it's completely useless! Especially when you press it by accident.
10. The Menu key which opens the context menu.
I know some people will probably say 'the [blah] key saved my life once...', but I just rebind these keys with AHK. (http://autohotkey.com)7 -
I hate this feeling.
Changing stuff with a greamripers scythe around my neck called doubt because the available data isn't too convincing.
Then having to go big or nothing as it is an ecosystem change (e.g. changing the cipher suites of TLS, changing protocol - e.g. HTTP 1.1 to 2) so it needs to be consistent as otherwise fun stuff could happen (fun as in the grim reaper cuts off my neck except a few centimeters and plays "now your head is off, now your head is on" ).
To top it off - just few seconds after the change has happened people coming up in the support channel.
My hands are - mysteriously - not sweaty then. Rather cold.
Lil prayer to the heavens and getting the whiskey bottle...
Opening an ongoing discussion in support channel....
And they're discussing whether the page needs to have an additional arrow for going back to the last page or if the default page navigation is enough.
Constantly using @all so everyone gets pissed off due to being pinged every few seconds in a channel that was meant for emergency support.
Now my hands go from a dark red to a bright red, my nostrils flare out, my adrenaline goes through the roof and I literally wanna murder people....
Those days.
I hate those days.
And I hate the timing of some people...
Like they're deliberately fucking with me without knowing it, like the universe told them explicitly to do so just to fuck with me.
*gooozfraba*
And of course, everything else is fine and running smooth like butter, except that said discussion now goes on in a total flamewar so I get even more pings.
Sucks to be in management.
You have way to many rooms where people can annoy you.
To top it off - after being grumpy and pissed and angry for people just annoying the fuck out of me, I have to mediate.
Yeah. Cause the usual person is on vacancy.
*slowly strangling the whiskey bottle like homer does with bart*
Turns out after 15 mins listening to enraged UX designer vs Frontend Team Lead that UX designer meant a completely different thing - uploaded wrong screenshot, whole discussion was unnecessary.
*Nah. Fuck it. Drinking whiskey*
Reminding everyone what the fucking frigging support channel is meant for and that penis fights aka who got the longest schlong don't belong there....
"Yeah it was a mistake, but it wasn't so bad"
...
You pinged fucking 32 people like it was the end of the world, you ignorant fucktwads.
For over 5 mins.
For fucking frigging nothing except your tiny dicks and shitty egos.
*Second round of whiskey*
Back to work after a wasted half hour.
What says monitoring?
Ah. Everything's working.
At least luck hasn't failed me.
Good server. Brave server.
Then I hear this lil voice in my head: no.
The servers know your personality.
They're afraid. Terrified.
Somehow that thought makes me giggle always...
Childish? Maybe. But it helps on those days.... Funnily enough, remaining 3 hours noone said anything in any chat channel.
"I wonder why, I wonder how...."... *hum* -
Coolest project I'll continually be working on.

Selling my Dad's famous BBQ sauces and rubs has been my hobby and passion for years. I'm lucky that my Dad was a computer enthusiast in the 1980's and also had a knack for marketing himself. All the while also being a somewhat famous character in the pioneering sport of competition BBQ cooking.
My brother and I shared the following machines growing up:
Commodore 64 w/ 2 Disk Drives, VicModem, & Tape Drive
Tandy 1000 Original Radio Shack IBM PC Clone
IBM 5150 w/ 20mb Hard Drive Expansion (Still Have This In Near Mint Condition)
Tandy 1000 RSX 386 with Win 3.11 For Networks
A Homebuilt Pentium 90 MHz Tower with Soundblaster and 16bit onboard video.
All that time on those machines learning various flavors of BASIC and crude graphic design got me where I am today.
That and learning how to BBQ... ;)8 -
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. -

Today I spent 9 hours trying to resolve an issue with .net core integration testing a project with soap services created using a third party soap library since .net core doesn't support soap anymore. And WCF is before my time.
The tests run in-process so that we can override services like the database, file storage, basically io settings but not code.
This morning I write the first test by creating a connected service reference to generate a service client. That way I don't need to worry about generating soap messages and keeping them in sync with the code.
I sent my first request and... Can't find endpoint.
3 hours later I learn via fiddler that a real request is being made. It's not using the virtual in-process server and http client, it's sending an actual network request that fiddler picks up, and of course that needs a real server accepting requests... Which I don't have.
So I start on MSDN. Please God help me. Nope. Nothing. Makes sense since soap is dead on .net core.
Now what? Nothing on the internet because above. Nothing in the third party soap library. Nothing. At this point I question of I have hit my wall as a developer.
Another 4 hours later I have reverse engineered the Microsoft code on GitHub and figured out that I am fucked. It's so hard to understand.
2 more hours later I have figured out a solution. It's pure filth..I hide it away in another tooling project and move all the filth to internal classes :D the equivalent of tidying your room as a kid by shoving it all under the bed. But fuck it.
My soap tests now use the correct http client with the virtual server. I am a magician.4 -
It looks like serving http/2 with Nginx is pretty easy. I want to move to that with my websites.
Do you have any experience with switching? Good or bad?4 -
The frontend developers in my company are the reason why I have anxiety. Here are few things that grinds my knees:
1) for a long time in projects, they deleted the auth token from their storage without integrating the logout api. They thought why use an API for that. :)
2) most of them had no clue that form fields could accept javascript as inputs and work as XSS vulnerabilities. This actually happened with a client, he got so fucking pissed.
3) One of them asked me to convert a PATCH request to DELETE cos fuck REST and HTTP methods.
For fuck’s sake. I need to get out of this place.4 -
The world must truly hate me.
I refactored my code a lot in order to easily integrate different APIs endpoints but then I can't use the one I specifically did this for, because of TLS errors.
My browsers all agree that it's fine, but curl and the 2 http libraries I tested can't fetxh any data.

FFS! having nodejs server on heroku, added certificate successfully for https, yet when going to www.example.com it uses http on prod and maintanence page while example.com goes to https.

List iteration - Implementation
How do you manipulate lists? In what language?
In my very limited knowledge:
1. C++ Iterators
2. D Ranges
3. Linked Lists

Does anybody have links for advantages for iterators? Why should I use them?2 -

So, I browse to a video livestream and an annoying ad starts before the livestream is shown. Furthermore, the page jumps around because of a cookie notification that also blocks some UI elements at the top.
Note: this is the website of a public (government-paid) national news website with very high standards and a good reputation.
Action 1: refresh page; I hope the ad is skipped. Nope, annoying ad restarts. Page jumps around again because of the cookie notification.
Action 2: accept cookies to remove notification blocking the top UI (it's OK, I know it can't actually save any cookies on my machine). Instead of some nice JS doing it for me in the background, the page refreshes because you know, HTTP requests and whatnot.
Annoying ad restarts again... FML 🤬
Lessons to be learned from this for any web dev: these annoyances can and *will* exponentially get worse if used simultaneously against your users, instead of being used to help or inform your users.
As a user of you website, I want to watch a livestream. I don't care what stupid legislation forced you to shove a fucking cookie notification in my face. Make sure it is not annoying me to the point that I close you website and take minutes to rant about it!
Also, give me the freedom of choice to watch an ad or not. You and I both know that some ads simply are not for me. Better save yourself and myself the bandwidth.
And go get good at web development. You're a news site. That's more than just text and images. If you want great apps, social media coverage, videos, live streams, blogs, etc. go get some better web devs. Your current web frontend devs only qualify to get fired.1 -

So, I started fiddling around APIs which returned data in JSON and parse that data in PHP and it feels so good.... Past 3 days I've been in deep learning PHP and practically $this is the best thing....
I need recommendations for such APIs, so far I've used
1. Chuck Norris Jokes (http://api.icndb.com/jokes/random/)
2. User's IP Address and details (http://ip-api.com/php/)
What would you recommend, let me know..1 -
Fucking retard Liferay.....
At least 2 users (one inour team and another at client's) are claiming they've successfully opened a portlet view multiple times at day X. And a month later it stopped working.
I open up Liferay's (tomcat's) localhost_access.log and can see all the portlet requests at day X have returned http:400
Normally I would consider the human factor and rule this as a human error, assuming they were connected to another environment, another server, etc. But since this is The Fucking Liferay - I'm not that fast in trusting even logs :(
Who the fuck made this piece of shit....6 -
Okay so.
I have a docker instance with 2 running apps. Normally one of them is just a proxy to the other one, so a http req to app0 is redirected to app1 and the same with response.
This works perfectly on bare machine, i can just rewrite the ip in the config file and it works. Now my boss decided that yeah docker is absolutely needed for this software so i have to containerize it.
Thing is docker seems to break local ips? I cant use localhost/, nor assigned ip. Is there a way i can debug this, or what should i look up??? Im lost, this is devops afaik and im far from devops.2 -

google play store and other google services keeps crashes, but other apps doesn't
when ignoring error popups, the app doesn't actually crash

Isn't this (not my code) callback hell all over again? The 2. http call expects results from the 1. http call. I feel like this could be solved cleaner using async await/switchMap/etc. ... but not like this.13 -

Need your help!
Tldr: how do I build a system with 2 power supplies so that I can power it from either one?
I'm currently working on a "video editing van" for an upcoming project and I found awesome atx power supplies that you can use on your normal car power source. Something like this: http://powerstream.com/DC-PC-12V.ht...
Here is where it gets tricky: obvioisly it would be easy to build a dedicated system for this purpose but I want to use an existing system with an existing psu. I still want to use the pc normally at home with the standard psu but don't fell like switching every single power connector everytime I take the pc into or out of the van. Do you have any idea how to make some sort of switching mechanism so that I can leave the Hardware as it is and just power it of any of the two psus?
Thanks in advance!8 -
I want to learn about the most important network protocols (HTTP 1/1.1/2, SSH, IMAP, SMTP, IMAP...) but reading the RFCs is extremely time consuming and probably not necessary for someone which doesn't need to implement these protocol.
Do you know more concise resources where I can learn more about the topic?9 -
So I’m going through a CKAD course. There is a section about checking the status of our Pods or the application running in it through Readiness/Liveness Probes— they mostly use an HTTP test, but there is a TCP option as well. My question is, how will the TCP test work on HTTP/2 given that it does not have TCP (it rather uses QUIC)? Sorry if this is a dumb question.1

Has anyone maybe a link to HTTP security topics in general?
I find often breadcrumbs, like in several different attack possibilities, but nothing comprehensive.
Mostly regarding HTTP 1.1 / HTTP 2 (h2c) and proxying.
I'm currently unclogging an whole ecosystem of proxies, endpoints, edge nodes and so on...
My knowledge is limited and it's frustrating to Google cause seemingly I get always just pieces of the puzzles but not a collection -.-
(Looking for specific information, e.g. regarding attacks like H2C Smuggling, HPACK attacks, stuff regarding Cookies / Headers / Encoding... But please not spread over several dozen pages where it becomes frustrating to read the same shit over and over again without learning something new :( )3 -
If anyone is good with dart (or) other single threaded programming languages, i have this small doubt about the inner workings of the event loop and such and i would like an explanation if possible.
If you're too lazy to goto the link:
1. I have a future returned from a http request.
2. a future.then is declared that prints the http result.
3. A separate while(true) loop is declared that runs forever that just prints natural numbers.
4. the while loop also has an await future.delay that waits for 1ms before continuing with the next iteration
My question :
1. There's only one thread so how does the http download code run WHILE my main loop is still executing.
2. my future.then event is not processed unless i await a future.delay separately for 1ms. returning control to the event loop ? i don't get it how does adding an event help it process a prior event? It's FIFO ?

Hell yeah, I love that feeling! I have absolutely no idea about working with the LEMP stack (nginx in particular) and I'm slowly figuring out how to get it working. Even tho I just noticed that chrome doesn't support npn for http/2 and that I am still up (GMT+1) I wanna continue working in this project. Man, I love that feeling <31 -
I'm teaching a couple of classes where students (~18 years old) work on their own projects. I just deleted two of those from my machine: one Angular and one Spring Boot, but just boilerplate. Together, they were about 500 MB. I spent 2-3 hours working on a little Go tool to make concurrent HTTP requests and to report statistics on the response time. The entire repository is roughly 500 kB in size, but solves a genuine problem. My students have a bloat ratio of 1000 compared to me as a baseline, but my stuff actually does things. Today, I programmed prime factorization in PHP for some load tests (mod_php vs. PHP-FPM). The PHP script is 1148 bytes long (but the file system reports 4 kB). My students could learn more from such a script than from their overblown "projects", but "PHP sucks" I hearsay, so let's bloat on.11

I recently started working on laravel. As the community says it was easy to get along with the framework and its methodologies. But then i had to do multiple login with framework in same domain.
Oh man, i spent a week to make it work. All those guards and middlewares realted to login was driving me crazy. The concept was clear, but somehow the framework was like "You! I shall make you spend a week for my satisfaction". The project demo was nearing and i was doing all kind of stuff i found. Atlast after continous tries it worked. Never in my 4+ years as a developer i had to face such an issue with login.
So here is how it works,if anyone faces the same issue:
(This case is beneficial if you're using table structures different from default laravel auth table structures)
1. Define the guards for each in auth.php
Eg:
'users' => [
'driver' => 'session',
'provider' => 'users',
],
'client' => [
'driver' => 'session',
'provider' => 'client',
],
'admin' => [
'driver' => 'session',
'provider' => 'admins',
],
2. Define providers for each guards in auth.php
'users' => [
'driver' => 'eloquent',
'model' => <Model Namespace>::class,
'table' => '<table name>', //Optional. You can define it in the model also
],
'admins' => [
'driver' => 'eloquent',
'model' => <Model Namespace>::class,
],
'client' => [
'driver' => 'eloquent',
'model' => <Model Namespace>::class,
],
Similarly you can define passwords for resetting passwords in auth.php
3. Edit login controller in app/Http/Controller/Auth folder accordingly
a. Usually this particular line of code is used for authentication
Auth::guard('<guard name>')->attempt(['email' => $request->email, 'password' => $request->password]);
b. If above mentioned method doesn't work, You can directly login using login method
EG:
$user = <model namespace>::where([
'username' => $request->username,
'password' => md5($request->password),
])->first();
Auth::guard('<guard name>')->login($user);
4. If you're using custom build table to store user details, then you should adjust the model for that particular table accordingly. NOTE: The model extends Authenticatable
EG
class <model name> extends Authenticatable
{
use Notifiable;
protected $table = "<table name>";
protected $guard = '<guard name>';
protected $fillable = [
'name' , 'username' , 'email' , 'password'
];
protected $hidden = [
'password' ,
];
//Below changes are optional, according to your need
public $timestamps = false;
const CREATED_AT = 'created_time';
const UPDATED_AT = 'updated_time';
//To get your custom id field, in this case username
public function getId()
{
return $this->username;
}
}
5. Create login views according to the user types you required
6. Update the RedirectIfAuthenticated middleware for auth redirections after login
7. Make sure to not use the default laravel Auth routes. This may cause some inconsistancy in workflow
The laravel version which i worked on and the solution is for is Laravel 6.x1 -

Doesn’t it bother anyone else that both HTTP/2 and HTTP/3 were both SPDY and QUIC at Google first? Yeah I know ideas have to “come from somewhere” and I guess it’s not really any different than the AT&T/Bell Labs/MIT of the past; but something doesn’t feel right.10

Anyone here use the NodeJS HTTP/2 API? I started working with it the other day and I can get static files served fine with it but when I try and use it's push feature to "bundle" additional resources that the page will need, it doesn't seem to work, the client still requests the resources from the server instead of looking in the "push" cache. Also the load time seems longer when using http/2 vs 1, was wondering if anyone else had come across these issues and found workarounds. P.S. - I'm using Chrome to test on, with https://localhost and some self-signed certs as http/2 isn't implemented in browser unless using https1

Um hey guys, so I was working with websockets in node.js and wanted to have some form of authentication. Did a bit of googling, read some docs and finally implemented something. It's just I am not sure if it is the right way. Can the experts give their 2 cents?
This is not a rant exactly, so if it comes under self promotion or irrelevant, please tell. 😃

Wow, angular is still a pile of shit in 2024, nothing changed.
I renew my https://devrant.com/rants/7582990 previous rant
I've recently switched to angular 17, not because I'm a masochist, but because, unfortunately, we have a huge portal for a super huge multinational enterprise and it's made in angular.
It's 2 years worth of work, and they've suddenly decided it's cool to switch to angular 17, because standards, because it's new etc.
Now that this crap angular 17 came out I prepared my hair pulling room, where there are whips and self torture instruments, and I've typed into browser url they "super new super modern super efficient" angular.dev, which apparently is their new official super 1337 documentation site (spoiler, it's shit as the other if not worse).
Since they realized angular was pigshit, they decided to eviscerate it like a sacrifical lamb in ancient maya age and add lot of stuff that makes it modern and more friendly.
They think they made the big bang of news, but they implemented stuff that exist since 10 years after people were cutting their wrists in their github "request a feature" section for years.
Well, to make it brief, they made a whole clunky obscure way to bootstrap it and didn't even had the decency and modesty to properly document it (they never learn, sigh....)
In any case I put up a .NET minimal API that works well, and a small angular app with a Hello world page that fetches a "hello word" string from a test api route.
The api works everywhere, browser, postman etc etc.
But ta-dahhhh, in angular throws error.
They put various way of using http client. Main 2 are withFetch() and without.
withFetch() says "as error "Invalid self signed certificate" and withoutFetch "Unknown error".
Apparently we have to do shenanigans also to do some dev development3 -
Some of my dev role models are not actually devs. I am always impressed when people make a tool they need without much programming experience. It highlights how the actual programming work doesn't have to be a hindrance, it's just a matter of sitting down and getting it done.
One if my favorite examples is Chris Huelsbeck who made his own sound engine and editor to emulate the extra virtual sound channels he needed on the Amiga. He actually emulated an emulator that someone had made OF the Amiga on the Atari ST.

Hi all! I want to share my site (https://tinytunes.app/ ) , which I completely created myself. Some information about how I created it:
1) I bought a domain that was freed from the previous owner (here https://mydrop.io/en/ )
2) Next, using the web archive, I restored the information of the main page - http://web.archive.org/web/...
3) website banner and logo created by myself using the service Canva
4) The theme for the site was used by Balanced Blog, but the main page of the site was created from scratch (without editing the template).
5) I added a few more pages to the site and a blog, which I am now actively filling
I would like to read the opinions of professionals: what was done wrong on the site, there may be some comments (some shortcomings, very noticeable) ...
From what I see myself: H1 headers - two instead of one (haven't figured out how to change that yet)
And the footer of the site - remove information about wordpress, add something like "2023 tinytunes.app All rights reserved. - I already figured out how to do this, I'll fix it soon)
I'm just starting to learn web programming, this site is only 3 months old. With knowledge of codes, everything is very weak for me - I study on my own from open free sources.15
