LONG RANT AHEAD!
In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.
mvn clean && mvn install
same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.
mvn clean && mvn install
the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...
Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...
I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.11 -
I came from a village, we have animals (like a farm), pigs, chicken, sometimes duck and goose. One day I had to work from home, bc had to come back to parents house. Our daily skype meeting was like this:
* discussing very important IT stuff *
* grandma rushes into my room *
me: sorry, but i have a meeting
grandma: i just wan...
me: but i cannot right no...
grandma: just wanted to know if...
me: grandma, I cannot right now, we have a skyp... im talking with colleagues, on the computer
grandma: * quiet voice * okay, i dont want to interrupt, I just want to know - Did you ordered the ducks?
* what I hear in headphones: collegues and boss LOLd sooo hard *
me: ffs, what ducks?
grandma: did your father not give you the guys number?
me: * starting to sweat * what guy? no he didnt, i have no idea what youre talking about
grandma: * disappointed * then who gonna order them...?
me: ...
grandma: * standing next to me, she hears the laughter * whats that?
since then, if im working from home every skype meeting starts with "Tommy, is your grandma there? HAHA!"7 -
Attended one of the best meetups ever. To give you an idea how awesome it was..
Speaker took the first ~20 minutes introducing himself.
His intro card deck kept referring to himself in the third person (he is the only employee in consulting 'company'). Ex. "Mr. Smith began his humble career .."
The powerpoint presentation began with him clicking each page, not executing the slideshow (ex. pressing F5).
Finally someone asked "Can you make slide bigger?"
S:"You can't read that?..um..sure...I guess .."
Starts fumbling around the zoom ...
Dev: "No, can you start the slideshow?"
S: "I don't know what you mean...there...I zoomed it, is that better? Now I can't see my notes..just sec.."
<fumbles again with the zoom>
Dev: "No, not zoom, start the slide show, press F5"
S: "Oh...you want me to F5 it...OK..."
<he *clicks* the slide show button>
Finally getting into code, trying to get out of powerpoint ...
S: "How do I get out of this fullscreen?.."
Dev: "Hit escape"
S:"No..um.."
<keeps trying to click on 'something'>
S:"I see visual studio, but its not on the big screen... "
<keeps click on 'something', no one is sure whats going on>
Dev: "Hit Escape to stop the slideshow"
<finally hits escape, then able to put Visual Studio on the big screen>
S: "Ahh...there, I figured it out."
Speaker had no end of making wild/random statements like:
".Net Core is the future of Microsoft, if you're using .Net 4.5...forget it, its not even supported anymore."
"When I was at Microsoft Build, I asked them why not put all the required .Net assemblies in one directory. Looks like with .Net Core, they listened to me" (he was serious)
"I don't use SQL Server Mgmt Studio. Its free and it sucks. I use <insert a very expensive SSMS clone>, its great, you guys should check it out", then proceeds to struggle to open a query window to write some SQL.
"When you use .Net Core and EntityFramework, you have to write your own stored procedures. If a developer can't write stored procedures, he shouldn't be in this business."
I was on the edge of my seat, hungry for the next crazy bat-shit thing to come out of his mouth. He did not disappoint. BEST MEETUP EVER!9 -
Because of hardware failure we had to move some vpns from one datacenter to another.
The team of highly untrained monkeys at my hosting provider were hired to do this. First they ran backups of all the systems. Then they started the moving process. A few hours later they were done. We got an email everything was back online.
So we restarted all our processes and no data was coming in from our Raspberry's around the country. So we start a little investigation. What did these buffons do, they changed our rsa keys.
So we kindly ask them to put the old keys back so we do not have to fix 200 changed key warnings on systems that are not remotely accesible.
Apperently something that can't be done because their back up process is automated and always makes new keys.
Holy fucking fuck, whats the point in having a backup its not an exact copy. Is this fucking normal?
Now I will be spending the next few weeks literally standing in cow shit reconnecting Raspberry's.
Thanks a fucking lot. Not!4 -
Me: Right, its Monday, time for a fresh start. Things have been unbearable, but i've nowhere else to go just yet. I gotta just dig deep, ignore everything bad and just get it done, It's all about positivity right? Lets just ignore the little things and keep moving.
*My morning so far, 2 hours in*
Remote dev: (timezone 5 hours earlier than me) Hey so whats the plan for this quarter?
Me: ... I posted a big detailed plan in the group chat on Friday night so you wouldn't be delayed ... but anyway, lets just move on. I need you to work on A, B and C. A is just copying what Android has already done, for B one of the backend guys working next to you is doing this, he'll be able to help you. C is all documented in the ticket.
Remote dev: cool thanks.
Local dev: So I was just chatting with remote dev ... yeah he told me he has no idea what he's suppose to do.
Me: ..... Ok i'll book a video call with him in the morning. Can't do it right now.
==========
Remote dev: Hey i'm helping the BE team do some testing. I found a bug in Android. Homepage says theres no trips. But Offers screen says there is.
Me: Ok so just to confirm, The "available" offers screen has offers to accept, but the white notification on the homepage saying "You have X offers to accept" is not showing up?
Remote dev: Correct!
*debugging for 5 mins*
Remote dev: actually no, the "accepted" offers tab has offers, but the homepage says there are no upcoming offers to work on.
Me: ..... ok, thats very different ... but sure, let me have a look.
Me: Right so the BE are ... again ... sending down expired offers. Looks like the accepted tab isn't catching it and the homepage is.
Remote dev: Right i'll open a ticket for Android.
Me: ... and BE team.
Remote dev: why?
Me: ... because they once again have timezone issues. This keeps causing issues in random places. BE need to fix this everywhere.
Remote dev: right, i'll chat to them and see if they can fix it.
==========
Product: So this ticket xxxxx is clear right?
Me: eh, kind of, so you want us to add feature X to user type A?
Product: correct.
Me: right but I don't see anywhere talking about the time it will take to build the screen for feature X
Product: What do you mean the screen?
Me: ... well, feature X is only accessible on screen Y ... we would have to change screen Y to support user type A ... you know ... so they can ... use the feature
Product: .... hhhhmmm .... i suppose you are right. Well we can't just add screen Y, we'll have to add W and Z, it won't make sense without them.
Me: ... ok sure, but our estimates put us over for this quarter. I don't think we can just add in 3 screens.
Product: No this is a must have.
Me: Ok so we'll have to drop something else.
Product: hhhmmm, don't think we can ... let me get back to you.

Backend team invited me to a meeting at 6am my time on Friday.

... 2 hours into Monday ... there must be vodka around here somewhere -
Overheating The Javascript Ecosystem
Paranoid thought: You know, in the course of every day, being the corrupt piece of shit that I am, whenever I see a scandal or what looks like shenanigans-in-the-making, I ask myself
"Wisecrack, is this a fucking scam or con of some sort?"
I was recently asking myself this about javascript.
Not the language per se, but the ecosystem.
I noticed how there are a thousand CLIs for simple shit. Another four thousand for page long libraries, for simpleton level shit (because prototypes are designed after satans own aborted love-child of object models). I noticed another eight thousand guys imitating steve jobs, talking at conferences and 'change the world' high-on-huffing-my-own-shit TEDX talks like rubyists that don't realize the world has moved on, all to hawk books and inflate CVs for cushy positions at major tech firms and the herd of dicksuckers following the next fad off a cliff like lemmings. And another eight thousand 'tech journalists' pushing them off the cliff while begging for outrage and hype dollars and slowly circling like vultures above the drain that is the ad-based economy.
And I thought to myself.
"Wisecrack, who benefits from all this noisy self-indulgent horseshit? Where is all the money coming from for all these books, conferences, meetings, publications, media, bread, and circuses?"
"I don't know wisecrack. But if I were the CEO of a big company, threatened by the prospect of a universal language, or universal platform, like flash, but one I couldn't kill like flash, I would try to do the most corrupt thing I could think of."
"Whats that wisecrack?"
"I would try to 'overheat' the ecosystem by selectively hiring people from that ecosystem, pumping money into a boatload of similar products, all in the hopes of provoking the equivalent of an immune overreaction, imitators all flooding the ecosystem with the same shit in different packages, self promoting sycophants, aggrenadizing social media idiots, tools sold as tools, hyped as 'the next coming of steve jobs', overcooked shit that focuses on ceremony over functionality, ritual over productivity, documentation over innovation like some sort of amazonion infinite nesting doll hellscape of documents linking to documents linking to documents, each one a new circle of dantes inferno, where the definition of anything links to another document that says "see also xyz", and I would convince them that they had done it to themselves."
And then I would push typescript as their lord, savior, and master. "
"How do you know all this wisecrack?"
"Because I am a piece of shit, and, this is what I would do in any executive's shoes."10 -
A mate from highschool contacted me the other day, offering me a job on this grand new idea he had.
So I said: "Allright, lets hear it, whats the idea?"
Him: "Trust me, its the next billion dollar app! It is a whole new social network for..."2 -
So today I realized that Im not happy.
When I was a kid I wanted to do many things because I had time and energy but I had no money. Now that Im an adult and I have the money, I have no energy and no will power to try and have personal life in these few hours left of my day. I spend 9 hours at work everyday and totally 1hr 30min is wasted on commuting.
I spent 4 years in uni between lectures and working on my side projects, and I really believed that after uni I will get a job and my life work balance will improve.
After uni I spent 2 years working abroad in 3 jobs at 3 countries. I work as android dev and now Im making a really decent salary.
However Im not happy at all. I realized that life is not about the money. Im changing countries like socks and dont even feel the need to socialize or enjoy my life anymore. Im european and these other eu countries are not that different at all. It came to a point where relationships are meaningless to me. I became an office drone who cares only about work and outside of work I care only about my projects and more work.
At this point im only 25 years old with around 2 years of experience and money is really good, but fuck it Im so tired of being an emigrant and having no stability in life. Im so drained. I spent past 6 years (4 in uni combined with side projects and 2 years working in 3 jobs in different countriee) working my ass off and lying to myself that after the next big thing Im gonna take a break and enjoy life. But its never enough. I dont want to hit 30s or 40s and realize that I wasted my life on pursuing money and didnt get to enjoy life..
Im really considering taking a 6-12 months vacation. I need to find myself. Probably going back to my own country. Just learn how to enjoy life, attend workshops, get to know new city area, meet new people, do some interesting hobbies. Maybe do a little freelance (max 10hrs a week).
Im tired of feeling like I need to make as much money as I can and learn as much about my work as I can. Its not rewarding because its never enough.
Whats the point in that money if I cant enjoy it?4 -
Food and computers.
Sorry for the fat people as well but i think those is legit.
I am sitting next to this friend of mine in class. She is a bit big. Anyhow.
She opens her laptop and i see her screen. Its dirty. But by dirty i mean fucking dirty. Like brow transparent circle like things all over.
I`m like: “shiiiet, whats that on your screen”.
She: “i am not really sure”.
2 days layer in another class we sit together again and she looks at me with a smile.
She: “look my screen is clean. It was dirty because sometimes o sit in bed and eat chicken then type on my keyboard,so when i close my computer the keys touch the screen and voiiiila!”
Me: “..... Wow”
She was quite proud she had elucidated the problem and did not really understand the meaning of my wow.4 -
getting into dev work is such a shit show. thinking back 2 years ago I decided to switch career so went on bootcamp and starting looking for junior role.
as you know full well all jobs requires 5+ years when the tech has only been around 3. Anyhow, got a junior full stack role at a start up, all good , great pace (cos of startup) and wide range of tech to learn. one minute i am doing great , next day I am not good enough and got let go (WTF?) ,also whats up with some backend devs Jesus why wouldnt you let me put a " on aws because you are the backend dev what the fuck is wrong with your ego man?
fun story number 2: after being let go of my first role due to being good dev for one day and bad the next. I went for an intern role for really low paid. well fair enough I am here to learn right guys? nope, i have experience with the main tech from my last job and I managed the take home test and despite I told them i have more experience front end they criticise my backend code , despite i was able to tell them what I have done not so well and I have found a better solution AT THE INTERVIEW. still not good enough. I was really doubting myself If I am that shit at being an fucking intern with a stack I have experience in.
fast forward another job interview I landed my current role with fantastic culture, good line manager & tech lead. nice colleague and I am being treated like a prince with the work i put in. Why is this industry so fucked?
so, folks out there trying to get into this game. dont lose hope, you can do it , you just need to get fucked a bit to know whats good out there!5 -
WOW!! What a fucking cop out. After what happened yesterday about branching. my senior and our boss had a meeting and I wasn’t included. My senior then message me to next time dont create another branch just use the existing branch even if it was merged. I said “ok but i thought thats the best practice, we we’re doing that since the beginning”. Senior then responded “Whats best practice for our boss, that will be our best practice” what a fucking cop out!!! Bitch!!23

So I joined this financial institution back in Nov. Selling themselves as looking for a developer to code micro-services for a Spring based project and deploying on Cloud. I packed my stuff, drove and moved to the big city 3500 km away. New start in life I thought!
Turns out that micro-services code is an old outdated 20 year old JBoss code, that was ported over to Spring 10 years ago, then let to rot and fester into a giant undocumented Spaghetti code. Microservices? Forget about that. And whats worse? This code is responsible for processing thousands of transactions every month and is currently deployed in PROD. Now its your responsibility and now you have to get new features complied on the damn thing. Whats even worse? They made 4 replicas of that project with different functionalities and now you're responsible for all. Ma'am, this project needs serious refactoring, if not a total redesign/build. Nope! Not doing this! Now go work at it.
It took me 2-3 months just to wrap my mind around this thing and implement some form of working unit tests. I have to work on all that code base by myself and deliver all by myself! naturally, I was delayed in my delivery but I finally managed to deliver.
Time for relief I thought! I wont be looking at this for a while. So they assign me the next project: Automate environment sync between PROD and QA server that is manually done so far. Easy beans right? And surely enough, the automation process is simple and straightforward...except it isnt! Why? Because I am not allowed access to the user Ids and 3rd party software used in the sync process. Database and Data WareHouse data manipulation part is same story too. I ask for access and I get denied over and over again. I try to think of workarounds and I managed to do two using jenkins pipeline and local scripts. But those processes that need 3rd party software access? I cannot do anything! How am I supposed to automate job schedule import on autosys when I DONT HAVE ACCESS!! But noo! I must think of plan B! There is no plan B! Rather than thinking of workarounds, how about getting your access privileges right and get it right the first time!!
They pay relatively well but damn, you will lose your sanity as a programmer.
God, oh god, please bless me with a better job soon so I can escape this programming hell hole.
I will never work in finance again. I don't recommend it, unless you're on the tail end of your career and you want something stable & don't give a damn about proper software engineering principles anymore.3 -
My story about ego boost was when client came one day that they want some system that was prommised to him but guy who promissed him it forgotten about it.
Well, i quickly estimated things in head (i wasnt on meeting, was next to this room so i heared whats up), i pulled out my boss from meeting ("hey i need you urgently for sth") told him that i can make proof of concept to show him for next day (it was +-15) and sure enough, next day 10:00 first version that worked but was kindda rough around edges and with TON of technical debt was created. Than I told client that I just need a little bit more time to work on this as he can see it is here, it works, and it does what he needs, but it would be good to add some polish to it.
He bought my version and i saved company a client, that was lost becose some moron forgotten about him hah
Oh, yes, i got all i needed in return, day off and some extra $$ -
Project manager, who i've complained in the past is neglecting critical things that he doesn't want to do, decided today to cancel our weekly planning meeting, to have the below conversation with me 1:1. Its very long, but anyone who has the will to get through it ... please tell me it's not just me. I'm so bewildered and angry.
Side note: His solution to the planning meeting not taking place ... to just not have one and asked everyone to figure it out themselves offline, with no guidance on priorities.
Conversation:
PM: I need to talk to you about some of phrasing you use during collaboration. It's coming across slightly offensive, or angry or something like that.
Me: ok, can you give me an example?
PM: The ticket I opened yesterday, where you closed it with a comment something along the lines of "as discussed several times before, this is an issue with library X, can't be fixed until Y ...".
"As discussed several times" comes across aggressive.
Me: Ok, fair enough, I get quite frustrated when we are under a crunch, working long hours, and I have to keep debugging or responding to the same tickets over and over. I mean, like we do need to solve this problem, I don't think its fair that we just keep ignoring this.
PM: See this is the problem, you never told me.
Me: ... told you what?
PM: That this is a known issue and not to test it.
Me: ..... i'm sorry ..... I did, that was the comment, this is the 4th ticket i've closed about it.
PM: Right but when you sent me this app, you never said "don't test this".
Me: But I told you that, the last 3 times that it won't be in until feature X, which you know is next month.
PM: No, you need to tell me on each internal release what not to test.
Me: But we release multiple times per week internally. Do you really need me to write a big list of "still broken, still broken, still broken, still broken"?
PM: Yes, how else will I know?
Me: This is documented, the last QA contractor we had work for us, wrote a lot of this down. Its in other tickets that are still open, or notes on test cases etc. You were tagged in all of these too. Can you not read those? and not test them unless I say I've fixed them?
PM: No, i'm only filling for QA until we hire a full time. Thats QA's job to read those and maintain those documents.
Me: So you want me to document for you every single release, whats already documented in a different place?
PM: ok we'll come back to this. Speaking of hiring QA. You left a comment on the excel spreadsheet questioning my decision, publicly, thats not ok.
Me: When I asked why my top pick was rejected?
PM: Yes. Its great that you are involved in this, but I have to work closely with this person and I said no, is that not enough?
Me: Well you asked me to participate, reviewing resumes's and interviewing people. And I also have to work extremely close with this person.
PM: Are you doubting my ability to interview or filter people?
Me: ..... well a little bit yeah. You asked me to interview your top pick after you interviewed her and thought she was great. She was very under qualified. And the second resume you picked was missing 50% of the requirements we asked for ... given those two didn't go well, I do think its fair to ask why my top pick was rejected? ... even just to know the reason?
PM: Could you not have asked publicly? face to face?
Me: you tagged me on a google sheet, asking me to review a resume, and rather than tag you back on 2 rows below ... you want me to wait 4 days to ask you at our next face to face? (which you just cancelled for this meeting)
PM: That would have been more appropriate
Me: ..... i'm sorry, i don't want to be rude but thats ridiculous and very nit pick-y. You asked my opinion on one row, I asked yours on another. To say theres anything wrong with that is ridiculous
PM: Well we are going to call another team meeting and discuss all this face to face then, because this isn't working. We need to jump to this other call now, lets leave it here.5 -
1) Submitted my CV
2) Got an email to schedule a phone interview for the next week, I gave ~5 appiointments on the next week that were good for me

13) I neveg got reply and did not ping for the 4th time
This was the most annoying and ridiculous recruiting process I had to deal with. It was just a waste of time.1 -
I just saw Kickstarter's blog post about moving over to the Blockchain. They're doing it because, uh, protocols, or something. No joke, here's a direct quote from their post:
"You may have heard of HTTP (Hypertext Transfer Protocol) which helps you browse the web, or SMTP (Simple Mail Transfer Protocol) which helps you send email. Protocols like these make up the unseen infrastructure of the internet. Imagine that, but for crowdfunding creative projects."
What the fuck does that even mean? The rest of the blog post is more of the same. They packed it full of every crypto buzzword they could find while also not actually providing any useful information.

Lately my sister's sound wasn't working. So i came over to see, whats wrong. Her boyfriend was also there, who claims to be a programmer himself, so i asked myself why he hasn't already solved the issue. But instead of asking, i just got on her computer and looked around.
First, i checked the audio jack, which was plugged in normally. There's a little wheel on the table, controlling the volume. There was a little light on it, shining. I assumed, it had to be a software problem and got into Windows' Audio Manager. Everything was okay. I spent the next 10 minutes checking EVERYTHING, even tried a restart (obviously changed nothing, but you never know ;D ). Drivers, Audio Settings, everything was okay.
Desperately I leant back in the chair and shot some looks around. Turns out, the plug wasn't plugged in. *facepalm*
The little light, shining on the wheel, seems to get its power through the audio jack.
It's always the simplest thing.3 -
In the 90s most people had touched grass, but few touched a computer.
In the 2090s most people will have touched a computer, but not grass.
But at least we'll have fully sentient dildos armed with laser guns to mildly stimulate our mandatory attached cyber-clits, or alternatively annihilate thought criminals.
In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.
The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.
Whats left after filtering, is strictly the primes.
I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.
I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).
Well, imagine my surprise when I had zero false positives.
Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.
My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.
I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.
I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.
The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.
If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.16 -
Heyo, it's me. That fool who always says shit about unity.(:
So.. i just got my first real hands-on down, and phew, i gotta say.. I overestimated that heap of bullshit.
It's not like there are basic concepts of gamedev, framebased ticking and stuff like that since before the fucking gameboy - nope - let's do shit different. More ... Shit. First, we invent something new. Lets call it "prefab". None of these fuckers is going to know what that shit is.
What next.. oh the new-keyword. That's bullshit, all languages use it. Lets make Instanciate(). That's the stuff.
On we go, scenes. Most shit is statically created beforehand and used by scripts glued to stuff. Hell that so neat actually. Creating materials beforehand and then we can just load em!(:
NOPE. yo bro your Material where u used one of those loading-methods is null. We ain't telling you whats wrong, cus you know.. Load() returning null is like completely normal, why throwing an exception?
Oh and btw, it needs to be in ./Resources/, but it wont make any difference.
So now you want to google your problem, eh? Forget it. The Forums only answer on stuff like "how to add 2 numbers in unity" and the guide shows you how you did it, but they say it works that way.
Dude holy shit, of course this is a buhuuu i don't know how to do shit rant because i feel like good 8-10 years of dev experience collected while not doing homework for school were for fucking nothing.:b
And i have to use it.
Subjective Opinion: Unity was made by crackheads.7 -
So... I take over this one ticket to test... the ticket mentions some visual component popping up when a button is clicked. It says there is a success and a failure message. The title of the story also mentions another functionality.
I start testing and some fellow QA asks me why I'm testing in this environment. Turns out, three people are sharing one environment and three different things are deployed...
I ask the dev whats going on because I heard there are multiple people deploying stuff...
He just tells me "oh, my changes are deployed I just checked".
I tell him that it's not about that but about communication and testing one thing at the time. Then I tell him, that I wouldn't test until his stuff is the only stuff there.
Some time later he hits me up again, now with the env to himself.
I test and quickly I see, that there is only the positive message even when I make sure that the backend is not reachable. I tell the dev what I found and he tells me "oh no, it's just the implementation of the popup thing, it's just frontend for now"...
I tell him, that the ticket should say so.
No answer for like 1-2 hours. Then I get an "ok".
End of the day.
Next day I come in and the fellow QA tells me, that the dev asked him to test the ticket.
I ask him if he changed anything about the scope of the ticket, he says no...
I'm like "ok... know what... begin testing and then tell him what I already told him".
So he's testing and then tells him again to update the scope.
Later in the daily the the dev's update is besically "they won't test my ticket..."
It would have taken him like 1 fucking minute to update the ticket...
The whole QA team was always trying to being helpful and even when the tickets where sometimes not 100% clear we always made it work... but now we are more and more going towards "MR does not meet ticketdescription, fix it" and "I don't care if its just a small thing... fix it and then come back to me"...
Seriously frustrating some times...2 -

Have a question about my career:
So far my career out of uni has been like this:
8 months in first place working as C# .NET dev, creating native desktop apps for windows. job was shitty, was not getting any best practices skills so I left.
12 months in 2nd place working as android dev in a startup. was working all alone and had to rebuilt my app up to 5-6 times to learn best practices. startup didnt care about android app at all so I left and now doing just some small freelance work for them.
3 months in new startup as android dev.Today I was told that its decided to focus on iOS and do all marketing (also uplift of new design) only on iOS. basically for next 3-4 months they don't plan to do much on android side. they saw that I showed some interest in backend and now they are asking me to talk with two other senior guys about starting with some small tasks for me on backend.
Our backend is mainly using python. Also backend guys will be pretty busy for next few months because they will have to deliver many new features in next few upcoming months. I've talked with one of them and he said that this is a bad idea to force frontend to start working on backend. However I feel that he's sort of gateekeping and probably just doesn't want to help me with getting up to speed.
In my defense, my knowledge doesn't end with C# .NET desktop apps and native mobile apps for android.
I have hobbie projects (gameservers) where I worked on websites (php,html,css,javascript,mysql) and also was taking care of a java based gameserver which is hosted in a linux vps.
Also I've had a small hosting "company" where with available tools I've managed to automate VPS(virtual private server) ordering, web hosting ordering and domain ordering. Basically I owned a dedicated server and did everything using whmcs, cpanel and proxmox virtualization.
I trust myself in learning this backend stuff and doing whats required, however I learned everything by myself and I won't follow all of these best practices.
Should I accept more responsibility on backend or should I continue focusing on android?7 -
I'm faszinated by some dev's ability to write legacy code.
Not maintaining but plainly creating code so horrible, that it can be considered legacy.
I wrote a new API for a silly Application because the old one had hardly anything to do with rest. At all. And despite the code being only 2 years old, it was still unmaintainable.
Now that I'm finish with this task, i got the next generation of the angular Frontend.
A guy wrote a completely new version of the frontend in angular5.
Only untyped variables, no documentation, no tests at all, no idea whats going on where,....
I thought my job was to adjust a few URL's and change some DTO's, but now i have to refactor everything again...
And the pain continues.....3 -
Once I wrote a shell script to solve a problem. Then I thought "now I have to rewrite it in a REAL language". So I did it in Go. But then I got bored and left it to rot in my gh. I picked it up again today and made another rewrite, but now in node. What the actual fuck4

tl;dr
You know that feeling when you have your headphones on and somebody is talking to you and then your stomach starts to hurt, because you don't want to put down your headphones because the music is great and your headphones plays it really good?
The post
I cannot code without headphones on. I'm currently on a longterm journey to find the best over-the-head budget headphones for coding, just out of curiosity, I started with cheap Phillips headphones for a couple of euros (9 or 10 i don't rem.), I would say they are usable, for a casual user, but far-far from the best
Then i purchased a Sennheiser HD451 for like 3x the price of the Phillips, really good. I use them in work and wanted to go on with the comparison so i bought a ATH m30x for home, and for gods sake, they are soo fucking good, way better what i would expect from a budget headphone, it cost twice the price of the Sennheiser.
Whats your "daily driver"? What would you suggest to try next?
note: before these I was using earbuds which came with my cellphones and 2.1 systems5 -
I started my career almost 20 years ago now.
I had the chance to work in really good environments, and with people trying to be performant. In my first company, the CTO pushed a lot the new/shiny XP method. Then I used the first iterations of Scrum as a Team Leader.
As I became a Service Manager, I found my love in kanban/lean (and my worst nightmare in sigma six).
I crashed startups created with friends and cashed out sometimes.
I also did a lot of "agile consulting", around productivity, product methods, organization (even got certified SaFe, the Agile framework that states" process over people").
When I came back to Europe, I just wanted to get back to the level I was in North America.
I have done a lot of mentoring, but now I lack the motivation (and time) to keep doing it, the way I did. So I stopped.
And now I have to answer the question "do I leave delivery?". Also, it seems that a lot of actual organizations are starting to put the product under " tech top management" ( companies I like at least).
So I wonder, what my next evolution should be...
Should I leave tech delivery to be fully Top-Management...
Do I want to structure/handle/organize the Product Teams...
Covid has given me time to start thinking a lot more about my situation... And it sucks... -
Story of my first successful project
Being part of a great team, I've shared in a lot of successes, one I am particularly proud of is my first attempt to use agile methodologies in a deeply waterfall-managment culture.
Time was June/July-ish and we applied for a national quality award where one key element in the application stated how well we handled customer complaint resolution.
While somewhat true (our customer service is the top-shelf good stuff), we did not have a systematic process in resolving customer complaints. Long story short,
the VP lied on her section of the application. Then came the 'emergency', borderline panic meeting (several VPs, managers, etc) to develop a process to better manage
complaints before the in-house inspection in December.
As most top priority projects go, the dev manager allocated 3 developers, 2 DBAs, and any/all network admins we would need (plus all the bureaucratic management that wanted their thumb in the pie).
Fast forward to August, after many, many planning meetings, lost interest, new shiny bouncing balls, I was the only one left on the project. The VP runs into the dev manager in the hallway and asks "Is my program done yet? If its not ready before December with report-able data, we will not win the award."
The <bleep> hit the fan...dev manager comes by...
Frank: "How the application coming along? Almost done?"
Me:"No, haven't really started coding. You moved Jake and Tom over to James's team, Tina quit, and you've had me sidetracked helping other teams because the DBAs are too busy."
Frank: "So, it's excuses. You really think the national quality award auditors care about your excuses? The specification design document has been done for months. This is unacceptable."
Me: "The VP finished up her section yesterday and according to the process, we can't start coding until the document is signed off."
Frank: "Holy f<bleep>ing sh<bleep>t! No one told you *you* couldn't start. You know how to create tables and write code."
Me: "There is no specification to write to. The design document is all about how they plan on reporting the data, not how call agents will be using the application to serve customers."
Frank: "The f<bleep> it isn't. F<bleep>ing monkeys could code against that specification, I helped write it! NO MORE F<bleep>ING EXCUSES! This is your top priority from now on!"
I was 'cleared' to work directly with the call center manager and the VP to develop a fully integrated customer complaint management system before December (by-passing any of the waterfall processes that would get in the way).
I had heard about this 'agile' stuff, attended a few conference tracks on the subject, read the manifesto, and thought "I could do this.".
Over the next month, I had my own 'sprints' and 'scrums' with the manager (at the time, 'agile' was a dirty word so I had to be careful of my words and what info I shared) and by the 2nd iteration had a working prototype.
Feature here, feature there (documenting the 'whys' and 'whats' along the way), and by October, had a full deployed application.
Not thinking I would get a parade or anything, the dev manager came back from a meeting where the VP was showing off the new app to the other VPs (and how she didn't really 'lie' on the application)
Frank: "Everyone is pleased how well the project turned out, except one thing. Erin said you bothered him too much with too many questions."
Me: "Bothered? Did he really say that?"
Frank: "No, not directly, but he said you would stop by his office every day to show him your progress and if he needed you to change anything. You shouldn't have done that."
Me: "Erin really seemed to like the continuous feedback. What we have now is very different than what we started with."
Frank: "Yes, probably because you kept bothering him and not following the specification document. That is why we spend so much time up front in design is so we don't waste management's time, which is exactly what you did."
Me: "We beat the deadline by two months, so I don't think I wasted anyone's time. In fact, this is kind of a big win for us, right?"
Frank: "Not really. There was breakdown in the process. We need better focus on the process, not in these one-hit-wonders."
End the end, the company won the award (mgmt team got to meet the vice president, yes the #2 guy). I know I played a very small, somewhat insignificant role in that victory, I was extremely proud to be part of the team. -
The fucking release process. We release weekly which is stressful for both Devs and QA’s. Everything should be committed/promoted in our DVCS by Thursday and should be verified beforehand. The problem is, QA’s doesn’t take development builds, they only want to take whats fucking next in release. In other words WE. FUCKING. RELEASE. UNTESTED. SOFTWARE.
Man, BA’s have it easy on our team.1 -
First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P
Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.
Numerical Methods...
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think
Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee
And finally
Practice practice
Projects projects
like honestly
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output
Team work skills and tools (VCS, communicating, project management, etc.)
Documentation and Reporting
Properly
:)
maybe even with LaTeX :D
Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude. -
does this happen to anyone else?
so every time i am happy, but like really happy and everything in the day goes very well, i am thankful for being alive and truly love life etc, at the end of that day or the next day something hits me and i fall into depression because i remember all the problems i was ignoring while being happy. this has actually happened a lot of times so every time i am really happy i automatically remember how is this temporary happiness gonna end, so i try hard not to be happy in order to avoid deeper depression later. and whats the point of living if ur not happy?4 -
[ WEBDEV frontend QUESTION ]
I will need to build a new admin dashboard for representing a lot of data from the api. the API is written in PHP and this won't change. We are currently using jquery to make the data interactive (choose date ranges, different filters and so on). Were currently using morris.js for charts. I'm thinking this would be a good opportunity to learn and use a new js framework to make the data more easily bindable on buttons and selects (not so many listeners on buttons and shit like that).I will be developing the front end on my own, alone, so i mostly have freedom here. I need something that has implementations of chart rendering, and which I could learn in a week or two in the evenings after work (starting to work on this in the next week probably). What are your guys recommendation? Whats the best option for dashboards js wise? I was thinking vue, won't I shoot myself in the foot for using a new technology(for me anyway) right from the bat?2 -

Im literally laughing and crying rn
I tried to deploy a backend on aws Fargate for the first time. Never used Fargate until now
After several days of brainwreck of trial and error
After Fucking around to find out
After Multiple failures to deploy the backend app on AWS Fargate
After Multiple times of deleting the whole infrastructure and redoing everything again
After trying to create the infrastructure through terraform, where 60% of it has worked but the remaining parts have failed
After then scraping off terraform and doing everything manually via AWS ui dashboard because im that much desperate now and just want to see my fucking backend work on aws and i dont care how it will be done anymore
I have finally deployed the backend, successfully
I am yet unsure of what the fuck is going on. I followed an article. Basically i deployed the backend using:
- RDS
- ECS
- ECR
- VPC
- ALB
You may wonder am i fucking retarded to fail this hard for just deploying a backend to aws?
No. Its much deeper than you think. I deployed it on a real world production ready app way.
- VPC with 2 public and 2 private subnets. Private subnets used only for RDS. Public for ALB.
- Everything is very well done and secure. 3 security groups: 1 for ALB (port 80), 1 for Fargate (port 8080, the one the backend is running on), 1 for RDS postgres (port 5432). Each one stacked on top and chained
- custom domain name + SSL certificate so i can have a clean version of the fully working backend such as https://api.shitstain.com
- custom ECS cluster
- custom target groups
- task definitions
Etc.
Right now im unsure how all of this is glued together. I have no idea why this works and why my backend is secure and reachable. Well i do know to some extent but not everything.
To know everything, I'll now ask some dumbass questions:
1. What is ECS used for?
2. What is a task definition and why do i need it?
3. What does Fargate do exactly? As far as i understood its a on-demand use of a backend. Almost like serverless backend? Like i get billed only when the backend is used by someone?
4. What is a target group and why do i need it?
5. Ive read somewhere theres a difference between using Fargate and... ECS (or is it something else)? Whats the difference?
Everything else i understand well enough.
In the meantime I'll now start analyzing researching and understanding deeply what happened here and why this works. I'll also turn all of this in terraform. I'll also build a custom gitlab CI/CD to automate all of this shit and deploy to fargate prod app

Im pissing and shitting a lot today. I piss so much and i only drink coffee. But the bigger problem is i can barely manage to hold my piss. It feels like i need to piss asap or im gonna piss myself. I used to be able to easily hold it for hours now i can barely do it for seconds. While i was sleeping with my gf @retoor i woke up by pissing on myself on her bed right next to her! the heavy warmness of my piss woke me up. It was so embarrassing. But she was hardcore sleeping and didnt notice. I immediately got out of bed to take a shower like a walking dead. I thought i was dreaming. I was half conscious and could barely see only to find out it wasnt a dream and i really did piss on myself in her bed! What the fuck! Whats next, to uncontrollably shit on her bed while sleeping?! Hopefully i didnt get some infection. I feel healthy. But maybe all of this is one giant dream im having and all of u are not real9 -
Whats next...
Devcons coming up / discussions about tech or dev news highlights / how u even dev bro? -
Honestly, fuck my computer. I dual boot win10 and arch, and due to some work i had to do over on win10, its been 2-3months since i've booted back into linux. Today i decided to go update my stuff, turns out it wont even boot into to GUI. When i try to go in tty and upgrade everything with pacman, it gives me an error without even telling me whats the problem. Next i try to install it again to another hdd, doesnt work. Someone please kill me swiftly....9
