The university system is fucked.
I've been working in this industry for a few years now, but have been self taught for much longer. I'm only just starting college and I'm already angry.
What does a college degree really mean anymore? From some of the posts I've seen on devRant, it certainly doesn't ensure professional conduct, work ethic, or quality (shout out to the brave souls who deal with the lack of these daily). Companies should hire based on talent, not on a degree. Universities should focus more on real world applications or at least offer such programs for students interested in entering the workforce rather than research positions. A sizable chunk of universities' income (in the U.S. at least) comes from research and corporate sponsorships, and educating students is secondary to that. Nowadays education is treated as a business instead of a tool to create value in the world. That's what I signed up for, anyway - gaining the knowledge to create value in the world. And yet I along with many others feel so restricted, so bogged down with requirements, fees, shitty professors, and shitty university resources. There is so much knowledge out there that can be put to instant practical use - I am constantly shocked at the things left out of my college curriculum (lack of automated tests, version control, inadequate or inaccurate coverage of design patterns and philosophies) - things that are ABSOLUTELY essential to be successful in this career path.
It's wonderful that we eventually find the resources we need, or the motivation to develop essential skills, but it's sad that so many students in university lack proper direction through no fault of their own.
Fuck you, universities, for being so inflexible and consistently failing to serve your basic purpose - one of if not the most important purpose on this earth.
Fuck you, corporations, for hiring and paying based on degree. Fuck you, management, for being so ignorant about the industry you work in.
Fuck you, clients, who treat intelligent people like dirt, make unreasonable demands, pull some really shady shit, and perpetuate a damaging stereotype.
And fuck you to the developer who wrote my company's antipattern-filled, stringy-as-all hell codebase without comments. Just. Fuck you.17 -
--- GitHub 24-hour outage post mortem ---
As many of you will remember; Github fell over earlier this month and cracked its head on the counter top on the way down. For more or less a full 24 hours the repo-wrangling behemoth had inconsistent data being presented to users, slow response times and failing requests during common user actions such as reporting issues and questioning your career choice in code reviews.
It's been revealed in a post-mortem of the incident (link at the end of the article) that DB replication was the root cause of the chaos after a failing 100G network link was being replaced during routine maintenance. I don't pretend to be a rockstar-ninja-wizard DBA but after speaking with colleagues who went a shade whiter when the term "replication" was used - It's hard to predict where a design decision will bite back and leave you untanging the web of lies and misinformation reported by the databases for weeks if not months after everything's gone a tad sideways.
When the link was yanked out of the east coast DC undergoing maintenance - Github's "Orchestrator" software did exactly what it was meant to do; It hit the "ohshi" button and failed over to another DC that wasn't reporting any issues. The hitch in the master plan was that when connectivity came back up at the east coast DC, Orchestrator was unable to (un)fail-over back to the east coast DC due to each cluster containing data the other didn't have.
At this point it's reasonable to assume that pants were turning funny colours - Monitoring systems across the board started squealing, firing off messages to engineers demanding they rouse from the land of nod and snap back to reality, that was a bit more "on-fire" than usual. A quick call to Orchestrator's API returned a result set that only contained database servers from the west coast - none of the east coast servers had responded.
Come 11pm UTC (about 10 minutes after the initial pant re-colouring) engineers realised they were well and truly backed into a corner, the site was flipped into "Yellow" status and internal mechanisms for deployments were locked out. 5 minutes later an Incident Co-ordinator was dragged from their lair by the status change and almost immediately flipped the site into "Red" status, a move i can only hope was accompanied by all the lights going red and klaxons sounding.
Even more engineers were roused from their slumber to help with the recovery effort, By this point hair was turning grey in real time - The fail-over DB cluster had been processing user data for nearly 40 minutes, every second that passed made the inevitable untangling process exponentially more difficult. Not long after this Github made the call to pause webhooks and Github Pages builds in an attempt to prevent further data loss, causing disruption to those of us using Github as a way of kicking off our deployment processes (myself included, I had to SSH in and run a git pull myself like some kind of savage).
Glossing over several more "And then things were still broken" sections of the post mortem; Clever engineers with their heads screwed on the right way successfully executed what i can only imagine was a large, complex and risky plan to untangle the mess and restore functionality. Github was picked up off the kitchen floor and promptly placed in a comfy chair with a sweet tea to recover. The enormous backlog of webhooks and Pages builds was caught up with and everything was more or less back to normal.
It goes to show that even the best laid plan rarely survives first contact with the enemy, In this case a failing 100G network link somewhere inside an east coast data center.

I was interviewing a candidate for a senior UI dev position and I began to ask him stuff about closures, contexts, design patterns and others.
At some point, after failing to respond to most of the questions, the candidate looked at me and said something like: ‘I am amazed. You didn’t have a lot of toys when you were a kid. The PC was your only toy when you were a kid, right??’.
I looked at my junior colleague that was shadowing the interview and we couldn’t believe what the guy was asking. He was extremely serious and he was looking for a way to find an explanation for his failure.11 -
On my former job we once bought a competing company that was failing.
Not for the code but for their customers.
But to make the transition easy we needed to understand their code and database to make a migration script.
And that was a real deep dive.
Their system was built on top of a home grown platform intended to let customers design their own business flows which meant it contained solutions for forms and workflow path design. But that never hit of so instead they used their own platform to design a new system for a more specific purpose.
This required some extra functionality and had it been for their customers to use that functionality would have been added to the platform.
But since they had given up on that they took an easy route and started adding direct references between the code and the configuration.
That is, in the configuration they added explicit class names and method names to be used as data store or for actions.
This was of cause never documented in any way.
And it also was a big contributing cause to their downfall as they hit a complexity they could not handle.
Even the slightest change required synchronizing between the config in the db and the compiled code, which meant you could not see mistakes in compilation but only by trying out every form and action that touched what you changed.
And without documentation or search tools that also meant that no one new could work the code, you had to know what used what to make any changes.
Luckily for us we mostly only needed to understand the storage in the database but even that took about a month to map out WITH the help of their developer ;)
It was not only the “inner platform” it was abusing and breaking the inner platform in more was I can count.
If you are going down the inner platform, at least make sure you go all the way and build it as if it was for the customers, then you at least keep it consistent and keep a clear border between platform and how it is used.12 -
I think I want to quit my first applicantion developer job 6 months in because of just how bad the code and deployment and.. Just everything, is.
I'm a C#/.net developer. Currently I'm working on some asp.net and sql stuff for this company.
We have no code standards. Our project manager is somewhere between useless and determinental. Our clients are unreasonable (its the government, so im a bit stifled on what I can say.) and expect absurd things from us. We have 0 automated tests and before I arrived all our infrastructure wasn't correct to our documentation... And we barely had any documentation to begin with.
The code is another horror story. It's out sourced C# asp.net, js and SQL code.. And to very bad programmers in India, no offense to the good ones, I know you exist. Its all spagheti. And half of it isn't spelled correctly.
We have a single, massive constant class that probably has over 2000 constants, I don't care to count. Our SQL projects are a mess with tons of quick fix scripts to run pre and post publishing. Our folder structure makes no sense (We have root/js and root/js1 to make you cringe.) our javascript is majoritly on the asp.net pages themselves inline, so we don't even have minification most of the time.
It's... God awful. The result of a billion and one quick fixes that nobody documented. The configuration alone has to have the same value put multiple times. And now our senior developer is getting the outsourced department to work on moving every SINGLE NORMAL STRING INTO THE DATABASE. That's right. Rather then putting them into some local resource file or anything sane, our website will now be drawing every single standard string from the database. Our SENIOR DEVELOPER thinks this is a good idea. I don't need to go into detail about how slow this is. Want to do it on boot? Fine. But they do it every time the page loads. It's absurd.
Our sql database design is an absolute atrocity. You have to join several tables together just to get anything done. Half of our SP's are failing all the time because nobody really understands the design. Its gloriously awful its like.. The epitome of failed database designs.
But rather then taking a step back and dealing with all the issues, we keep adding new features and other ones get left in the dust. Hell, we don't even have complete browser support yet. There were things on the website that were still running SILVERLIGHT. In 2019. I don't even know how to feel about it.
I brought up our insane technical debt to our PM who told me that we don't have time to worry about things like technical debt. They also wouldn't spend the time to teach me anything, saying they would rather outsource everything then take the time to teach me. So i did. I learned a huge chunk of it myself.
But calling this a developer job was a sick, twisted joke. All our lives revolve around bugnet. Our work is our BN's. So every issue the client emails about becomes BN's. I haven't developed anything. All I've done is clean up others mess.
Except for the one time they did have me develop something. And I did it right and took my time. And then they told me it took too long, forced me to release before it was ready, even though I had never worked on what I was doing before. And it worked. I did it.
They then told me it likely wouldn't even be used anyway. I wasn't very happy at all.
I then discovered quickly the horrors of wanting to make changes on production. In order to make changes to it, we have to... Get this
Write a huge document explaining why. Not to our management. To the customer. The customer wants us to 'request' to fix our application.
I feel like I am literally against a wall. A huge massive wall. I can't get constent from my PM to fix the shitty code they have as a result of outsourcing. I can't make changes without the customer asking why I would work on something that doesn't add something new for them. And I can't ask for any sort of help, and half of the people I have to ask help from don't even speak english very well so it makes it double hard to understand anything.
But what can I do? If I leave my job it leaves a lasting stain on my record that I am unsure if I can shake off.
... Well, thats my tl;dr rant. Im a junior, so maybe idk what the hell im talking about.rant code application bad project management annoying as hell bad code c++ bad client bad design application development16 -
Rant!
Been working on 'MVP' features of a new product for the past 14 months. Customer has no f**king clue on how to design for performance. An uncomfortable amount of faith was placed on the ORM (ORMs are not bad as long as you know what you are doing) and the magic that the current framework provides. (Again, magic is good so long as you understand what happens behind the smoke and mirrors - but f**k all that... coz hey, productivity, right?). Customer was so focussed on features that no one ever thought of giving any attention to subtler things like 'hey, my transaction is doing a gazillion joins across trizillion tables while making a million calls to the db - maybe I should put more f**king thought into my design.' We foresaw performance and concurrency issues and raised them way ahead of the release. How did the customer respond? By hiring a performance tester. Fair enough - but what did that translate into? Nothing. Nada. Zilch. Hiring a perf tester doesn't automagically fix issues. The perf tester did not have a stable environment, a stable build or anything that is required to do a test with meaningful results. As the release date approached, the customer launched a pilot and things started failing spectacularly with the system not able to support more than 15 concurrent users. WTF! (My 'I told you so' moment) Emails started flying in all directions and the hunt for the scapegoat was on (I'm a sucker for CYA so I was covered). People started pointing in all directions but no one bothered to take a step back and understand what was causing the issues. Numero uno reason for transaction failure was deadlocks. We were using a proprietary DB with kickass tooling. No one bothered to use the tooling to understand what was the resource in contention let alone how to fix the contention. Absolute panic - its like they just froze. Debugging shit and doing the same thing again and again just so that management knew they were upto something. Most of the indexes had a fragmentation of 99.8% - I shit you not. Anywho, we now have a 'war room' where the perf tester needs to script the entire project by tonight and come up with some numbers that will amount to nothing while we stay up and keep profiling the shit out of the application under load.
Lessons learnt - When you foresee a problem make a LOT of noise to get people to act upon it and not wait till it comes back and bites you in the ass. Better yet, try not to get into a team where people can't understand the implications of shitty design choices. War room my ass!3 -
Our team - if ever existed - is falling apart. Pressure raising. Release deadline probably failing. No release ready for Big Sur.
Almost seemed we were getting somewhere: More focus on code quality, unit tests, proper design, smaller classes. But somehow we now ended up in "microservice" hell; a gazillion classes, mostly tested in isolation, but together they just fail to do their job. A cheap and dirty proof of concept from March is still more capable than this pile. I really start to doubt all that "Clean code", TDD, Agility rhetorics. What does it help you, if nobody cares for the end result? It's like a month I try to hammer down that message: we have to have testable artifacts, we have to ensure code signing works, our artifact is packaged and installable, we have to give QA something they can test - but time just passes and this piece of shit software is still being killed or does nothing.
Now my knee is broken and can do no sports and are tied to my chair even more. To top it all my coffee machine broke and my internet connection was abysmal this week. Not the usual small disconnects, after which it would recover, but more annoying and enduring: often being throttled to 1.7 MB/s (ranking my connection in the slowest 7% even in Germany). My RDP sessions had compression artifacts all over the screen and a mouse click would only take effect 5 sec later.
But my Esspresso machine was just repaired. Not all hope is lost.7 -
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! -
Spend several months designing an alternative approach to string matching/parsing not based on parser combination or Regex. Benchmark and profile the ever living hell out of it. Find out the performance is highly competitive with FParsec and far easier on memory than either approach. Discover FParsec responds very badly when failing. Document all of this, do a presentation on the design. Upload video of presentation with links to it on a few sites. Presentation gets downvoted, and receive hatemail. Yay.18
