Seven months ago:
Project Manager: - "Guys, we need to make this brand new ProjectX, here are the specs. What do you think?"
Bored Old Lead: - "I was going to resign this week but you've convinced me, this is a challenge, I never worked with this stack, I'm staying! I'll gladly play with this framework I never used before, it seems to work with this libA I can use here and this libB that I can use here! Such fun!"
Project Manager: - "Awesome! I'm counting on you!"
Six months ago:
Cprn: - "So this part you asked me to implement is tons of work due to the way you're using libA. I really don't think we need it here. We could use a more common approach."
Bored Old Lead: - "No, I already rewrote parts of libB to work with libA, we're keeping it. Just do what's needed."
Cprn: - "Really? Oh, I see. It solves this one issue I'm having at least. Did you push the changes upstream?"
Bored Old Lead: - "No, nobody uses it like that, people don't need it."
Cprn: - "Wait... What? Then why did you even *think* about using those two libs together? It makes no sense."
Bored Old Lead: - "Come on, it's a challenge! Read it! Understand it! It'll make you a better coder!"
Four months ago:
Cprn: - "That version of the framework you used is loosing support next month. We really should update."
Bored Old Lead: - "Yeah, we can't. I changed some core framework mechanics and the patches won't work with the new version. I'd have to rewrite these."
Cprn: - "Please do?"
Bored Old Lead: - "Nah, it's a waste of time! We're not updating!"
Three months ago:
Bored Old Lead: - "The code you committed doesn't pass the tests."
Cprn: - "I just run it on my working copy and everything passes."
Bored Old Lead: - "Doesn't work on mine."
Cprn: - "Let me take a look... Ah! Here you go! You've misused these two options in the framework config for your dev environment."
Bored Old Lead: - "No, I had to hack them like that to work with libB."
Cprn: - "But the new framework version already brings everything we need from libB. We could just update and drop it."
Bored Old Lead: - "No! Can't update, remember?"
Bored Old Lead: - "You need to rewrite these tests. They work really slow. Two hours to pass all."
Cprn: - "What..? How come? I just run them on revision from this morning and all passed in a minute."
Bored Old Lead: - "Pull the changes and try again. I changed few input dataset objects and then copied results from error messages to assertions to make the tests pass and now it takes two hours. I've narrowed it to those weird tests here."
Cprn: - "Yeah, all of those use ORM. Maybe it's something with the model?"
Bored Old Lead: - "No, all is fine with the model. I was just there rewriting the way framework maps data types to accommodate for my new type that's really just an enum but I made it into a special custom object that needs special custom handling in the ORM. I haven't noticed any issues."
Cprn: - "What!? This makes *zero* sense! You're rewriting vendor code and expect everything to just work!? You're using libs that aren't designed to work together in production code because you wanted a challenge!?? And when everything blows up you're blaming my test code that you're feeding with incorrect dataset!??? See you on Monday, I'm going home! *door slam*"
Project Manager: - "Cprn, Bored Old Lead left on Friday. He said he can't work with you. You're responsible for Project X now."26
I recently joined the dark side - an agile consulting company (why and how is a long story). The first client I was assigned to was an international bank. The client wanted a web portal, that was at its core, just a massive web form for their users to perform data entry.
My company pitched and won the project even though they didn't have a single developer on their bench. The entire project team (including myself) was fast tracked through interviews and hired very rapidly so that they could staff the project (a fact I found out months later).
Although I had ~8 years of systems programming experience, my entire web development experience amounted to 12 weeks (a part time web dev course) just before I got hired.
I introduce to you, my team ...
Scrum Master. 12 years experience on paper.
Rote memorised the agile manifesto and scrum textbooks. He constantly went “We should do X instead of (practical thing) Y, because X is the agile way.” Easily pressured by the client to include ridiculous (real time chat in a form filling webpage), and sometimes near impossible features (undo at the keystroke level). He would just nag at the devs until someone mumbled ‘yes' just so that he would stfu and go away.
UX Designer. 3 years experience on paper ... as business analyst.
Zero professional experience in UX. Can’t use design tools like AI / photoshop. All he has is 10 weeks of UX bootcamp and a massive chip on his shoulder. The client wanted a web form, he designed a monstrosity that included several custom components that just HAD to be put in, because UX. When we asked for clarification the reply was a usually condescending “you guys don’t understand UX, just do <insert unhandled edge case>, this is intended."
Developer - PHD in his first job.
Invents programming puzzles to solve where there are none. The user story asked for a upload file button. He implemented a queue system that made use of custom metadata to detect file extensions, file size, and other attributes, so that he could determine which file to synchronously upload first.
Developer - Bootlicker. 5 years experience on paper.
He tried to ingratiate himself with the management from day 1. He also writes code I would fire interns and fail students for. His very first PR corrupted the database. The most recent one didn’t even compile.
Developer - Millennial fratboy with a business degree. 8 years experience on paper.
His entire knowledge of programming amounted to a single data structures class he took on Coursera. Claims that’s all he needs. His PRs was a single 4000+ line files, of which 3500+ failed the linter, had numerous bugs / console warnings / compile warnings, and implemented 60% of functionality requested in the user story. Also forget about getting his attention whenever one of the pretty secretaries walked by. He would leap out of his seat and waltz off to flirt.
Developer - Brooding loner. 6 years experience on paper.
His code works. It runs, in exponential time. Simply ignores you when you attempt to ask.
Developer - Agile fullstack developer extraordinaire. 8 years experience on paper.
Insists on doing the absolute minimum required in the user story, because more would be a waste. Does not believe in thinking ahead for edge conditions because it isn’t in the story. Every single PR is a hack around existing code. Sometimes he hacks a hack that was initially hacked by him. No one understands the components he maintains.
Developer - Team lead. 10 years of programming experience on paper.
Writes spaghetti code with if/else blocks nested 6 levels deep. When asked "how does this work ?”, the answer “I don’t know the details, but hey it works!”. Assigned as the team lead as he had the most experience on paper. Tries organise technical discussions during which he speaks absolute gibberish that either make no sense, or are complete misunderstandings of how our system actually works.
The last 2 guys are actually highly regarded by my company and are several pay grades above me. The rest were hired because my company was desperate to staff the project.
There are a 3 more guys I didn’t mention. The 4 of us literally carried the project. The codebase is ugly as hell because the others merge in each others crap. We have no unit tests, and It’s near impossible to start because of the quality of the code. But this junk works, and was deployed to production. Today is it actually hailed as a success story.
All these 3 guys have quit. 2 of them quit without a job. 1 found a new and better gig.
I’m still here because I need the money. There’s a tsunami of trash code waiting to fail in production, and I’m the only one left holding the fort.
Why am I surrounded by morons?
Why are these retards paid more than me?
Why are they so proud when all they produce is trash?
How on earth are they still hired?
And yeah, FML.7
UPDATE: devRant Trans-Oceanic Journey Community Project
It was a mere 12 days ago that I asked the question; 'Could devRanters, as a community, build a 21st Century Technology-Laden ‘devRant devie-Stressball-in-a-Bottle’ and send it on a journey across the Atlantic ocean?
I am thrilled to report that devRanters enthusiastically accepted this difficult challenge. A core team quickly formed and a tremendous amount of research and progress has been made in a short period of time. I want to give you a high level-flavor of what we are doing. Please keep in mind we still need your help. We welcome all develops to take part in this journey.
I want to give appreciation to the devRant Founders @dfox and @trogus. Without your support and sponsorship this project would not have been possible. devRant brought us together and it a reality. Devie journeying across the Ocean the Columbus sailed will stir the imagination of children and adults worldwide when we launch on May 1, 2017.
Some of the research and action items in progress:
- Slack and trello environments were created to capture research and foster discussion.
- A Stony Brook University Oceanography Professor suggested the Gulf Stream would be a good pathway across the ocean. We researched it very and agree. The Gulf Stream has been a trans-Atlantic conduit for hundreds of years. We are deciding whether to launch from Cape Hatteras, NC or the Virginia coast. Both have easy access to the rapid currents in the Gulf Stream.
- We are researching every detail of the Gulf Stream to make the journey easier and faster for devie. We have maps and a team member gathered valuable ideas reading a thorough book – ‘The Gulf Stream’.
- We decided on using a highly resilient plastic rather than glass for the bottle material. Plastic is much lighter, faster and glass breaks down more easily. The lightweight enclosure will allow us to take full advantage of waves and ample trade winds. We are still discussing the final design as we want to minimize friction and mimic the non-locomotion fish that migrate thousands of miles riding the Gulf Stream.
-The enclosure might be 3D printed unless we can locate a commercial solution. We have 3D specs and are speaking with some experts. There are advantages and dis-advantages to each solution.
- We will be using Iridiums' RockBLOCK two-way satellite technology to bounce lat-long coordinate pings off their 36 low-orbit satellites. The data will be analyzed by our devRant devie analysis software. IOS and Android public apps being built by the team will display devie's location throughout the journey in.
- Arduino will be used as the brains
- Multiple sensors including temperature and depth are being considered
-A project plan will be published to the team Friday 12/9. Sorry I am a few days late but adding some new ideas.
There are still a lot of challenges we must overcome and we will.
That’s all for now. I will send updates and all ideas / comments are valued.6

I'm only two step far from having an intelligent house, just missing finish my own domotic system and then a bot to control, music, TV, and electricity.
Let's do the list:
1.- Kodi on TV ✔
2.- MPD on a hidden PC inside my old grandpa's stereo ✔
3.- a small data server to provide music, movies and series to Kodi and mpd ✔
(This is something that im trying to do with spare PC's running Linux on my free time)
MPD on a PIII (500mhz + 512mb RAM)
Kodi on a dual core (2.80ghz +3gb RAM)
Server on a opteron (1.80ghz + 1.5gb RAM)4
I started two months ago a new role in a new company.
Together with 3 colleagues I manage a HUGE OpenStack platform (I’m talking about more than 300 customers, many petabytes of data, dozens of compute nodes 😍).
On Friday night a well-known multinational had the GREAT idea to update the software of one of the core components of the platform (Neutron).
Obviously it all went wrong and customers started to call and open tickets, so even if it was already past midnight we’ve been all called to arms.
As a workaround we had to rebuild ALL the networks, detach all the ports and reattach them to the VMs, with all the errors that came with this kind of operations, such as failing to get an internal/external IP, fail to boot etcetera.
What amuses me is the fact that the above-mentioned multinational just asked for logs with no solution (except for the above workaround) until Monday morning.
It has been a good weekend, i talked with professionals from all over the world, in various languages, and worked multi-tasking with two different computers, with a third that was used just to share my screen and VPN for the management network.
During this weekend I virtually met all the possible colleagues that I will meet in this new role, and it was pretty funny to see how they handle stress. (Badly if you ask)
I’ve been woken up at 7:30 after falling asleep at 6:45, I’ve slept 17 hours in 5 days, haven’t taken a shower in 5 days (I know, it happens, I worked from home) but it was worth it.
Not only and merely for the money (overtime work), but mainly for the job itself.
I love to handle this HUGE infrastructures for now, even if I think they have many limitations and many components could have been written better.
The best thing about this weekend was to meet a group of people from all over the country and the world that worked non-stop from Friday night until Wednesday night to solve the situation.
All of them understood me when I asked them questions, and didn’t treat me like the [insert random]science nerd that I am.
I felt like in the movies, in front of three monitors, working from the comfort of my chair, in my underwear, eating as fast as I could because I was constantly in call with someone.
Apart from that, WHAT THE FUCK WENT THROUGH YOUR HEAD TO DEPLOY AN UPDATE ON FRIDAY NIGHT, YOU FUCKING PIECE OF adorable man???
WHY COULDN’T YOU WAIT UNTIL MONDAY??? NOBODY USES THOSE SERVICES AT NIGHT APART FROM THE SCHEDULED JOBS!!!!!
I HOPE YOU’LL HAVE A LONG AND PROSPER LIFE, FULL OF JOY AND HAPPINESS5
Fucking cloud providers always trying to steal your shit and spy on your things, fucking prying eyes. That's why i've decided to go back hosting my own private cloud from home. Running on some very energy efficient shit: dual core intel atom cpu (so slow that it can't fucking run windows normally), 16gb of ram, because why the fuck not? and 1tb 2.5"hdd, along with unlimited data - 100/100 Mbit/s internet connection with a server response time less than 95ms just to backup my shitty Iphone selfies and cat pics, host some very important files and regularly back up my contacts. This shit runs CentOS, Nginx, https, bitch! This platform is more trustworthy than your shitty dropbox or whatever other shit they offer you. I can choose whether i back-up my shit from local network or over internetz, Costing me no more than 25€ annually(just to keep the machine on 24/7/365).14
@netikras since when does proprietary mean bad?
Lemme tell you 3 stories.
- come in to the office
- use internal resources (company newsletter, jira, etc.)
- connect to client's VPN using Cisco AnyConnect
- lose access to my company resources, because AnyConnect overwrites routing table (rather normal for VPN clients)
- issue a route command updating routing table so you could reach confluence page in the intranet
- route command executes successfully, `route -n` shows nothing has changed
- google this whole WTF case
- Cisco AnyConnect constantly overwrites OS routing table to ENFORCE you to use VPN settings and nothing else.
Sooo basically if you want to check your company's email, you have to disconnect from client's VPN, check email and reconnect again. Neat!
Can be easily resolved by using opensource VPN client -- openconnect
- get a server in your company
- connect it to client's VPN and keep the VPN running for data sync. VPN has to be UP at all times
- network glitch [uh-oh]
- VPN is no longer working, AnyConnect still believes everything is peachy. No reconnect attempts.
- service is unable to sync data w/ client's systems. Data gets outdated and eventually corrupted
OpenConnect (OSS alternative to AnyConnect) detects all network glitches, reports them to the log and attempts reconnect immediatelly. Subsequent reconnect attempts getting triggered with longer delays to not to spam network.
SYMANTEC VIP (alleged 2FA?):
- client's portal requires Sym VIP otp code to log in
- open up a browser in your laptop
- navigate to the portal
- enter your credentials
- click on a Sym VIP icon in the systray
- write down the shown otp number
- log in
umm... in what fucking way is that a secure 2FA? Everything is IN the same fucking device, a single click away.
Can be easily solved by opensource alternatives to Sym VIP app: they make HTTP calls to Symantec to register a new token and return you the whole totp url. You can convert that url to a qr code and scan it w/ your phone (e.g. Google's Authenticator). Now you have a true 2FA.
Proprietary is not always bad. There are good propr sw too. But the ones that are core to your BAU and are doing shit -- well these ARE bad. and w/o an oppurtunity to workaround/fix it yourself.15
Thanks to Devrant I've learned about rubber duck debugging. Never heard of it before! It reminds me of a story many moons ago when I worked for a certain multinational company as a business analyst. The company brought in some consultants who basically stole the work my team was already doing on a big project (a horrendous series of spreadsheets linked to data coming from the core systems) and sold it back to the company for an insane amount of money as their idea.
When they launched the new product, the team I was in was asked to test and review it. It took my colleague ten seconds to bring the whole thing to its knees and trigger a corrupt data export back into the core systems. Bearing in mind this external company somehow managed to charge tens of thousands of pounds. So what did my colleague do? Hack the system? Some kind of complicated sabotage? Nope. He typed "FISH" into one of the spreadsheet cells! Thus the FISH test was born.
That day I learned several things: it's easy to break things with a fish; the importance of validating your input; and the satisfaction of showing up the smug bastards who stole your ideas and work.3
A lot of engineering fads go in circle.
Architecture in the 80s: Mainframe and clients.
Architecture in the 90s: Software systems connected by an ESB.
Architecture in the 2000s: Big central service and everyone connects to it for everything
Architecture in the 2010s: Decentralized microservices that communicate with queues.
Current: RabbitMQ and Kafka.
... Can't we just go back to the 90s?
I hate fads.
I hate when I have to get some data, and it's scattered on 20 different servers, and to load a fucking account page, a convoluted network of 40 apps have to be activated, some in PHP, others in JS, others on Java, that are developed by different teams, connected to different tiny ass DBs, all on huge clusters of tiny ass virtual machines that get 30% load at peak hours, 90% of which comes from serializing and parsing messages. 40 people maintaining this nightmare, that could've been just 7 people making a small monolithic system that easily handles this workload on a 4-core server with 32GB of RAM.
Tripple it, put it behind a load balancer, proper DB replication (use fucking CockroachDB if you really want survivability), and you've got zero downtime at a fraction of the cost.
Just because something's cool now, doesn't mean that everybody has to blindly follow it for fucks sake!
Same rant goes for functional vs OOP and all that crap. Going blindly with any of these is just a stupid fad, and the main reason why companies need refactoring of legacy code.13
Last year, we had to do a big university project in randomly selected groups (5-6 students in every group).Three of the five guys were completely useless, I mean, both the other competent guy and me wrote around 20,000 lines of code each, the other ones wrote around 500 lines of code (combined).
After our first few meetings we quickly knew that we have to give them a small task which was so trivial that not even they can fuck it up. But we were wrong. Oh boy, so wrong.
They simply had to code the excel export of the data, which means they had to use two functions from a library and pass the correct data. But their solution was so bad, I lost faith in humanity and was fascinated by it at the same time.
For example, there was this simple class "Room", which had a few properties like size or number of seats and a few getter/setter etc. That was a core class and written by the other qualified guy. So how did the others fuck up the excel export? They somehow rewrote that class in German (although the other code was completely in English), implemented a function for each property that would write its value to a hardcoded cell in a hardcoded excel file.
And this was just the tip of the iceberg. Needlessly to say that I had to rewrite the whole export in the night before we had to present the project.5
Here in Italy we run a few exam simulation in order to prepare for finals in June.
One of the two categories of simulations, one of which revolves around the core subjects of our technical course which in my case is CompSci and Networking.
"Sounds good!" one would say.
And I'd agree, if only our CompSci professor graded solutions in a sensate manner.
If one does not exactly copy and paste the solutions we repated in class 100 times (which, by the way, are all EXACTLY the same solution but with different data in diagrams and other sections), the grade WILL be insufficient: no but's or why's.
This is only one of the prime examples of what school revolves around. Sometimes it just feels like we are trained to be sheeps in a world of wolves. Rinse and repeat over and over. No technical competency is (almost) ever valued or allowed to be expressed and is often looked down upon by old school professors who literally care about everything but their subject, students and school in general.
I'm glad this is almost over, and that greener pastures are ahead :)9
Ok friends let's try to compile Flownet2 with Torch. It's made by NVIDIA themselves so there won't be any problem at all with dependencies right?????? /s
Let's use Deep Learning AMI with a K80 on AWS, totally updated and ready to go super great always works with everything else.
> CUDA error
> CuDNN version mismatch
> CUDA versions overwrite
> Library paths not updated ever
> Torch 0.4.1 doesn't work so have to go back to Torch 0.4
> Flownet doesn't compile, get bunch of CUDA errors piece of shit code
> online forums have lots of questions and 0 answers
> Decide to skip straight to vid2vid
> More cuda errors
> Can't compile the fucking 2d kernel
> Through some act of God reinstalling cuda and CuDNN, manage to finally compile Flownet2
> Try running
> "Kernel image" error
> Try without a label map because fuck it the instructions and flags they gave are basically guaranteed not to work, it's fucking Nvidia amirite
> Enormous fucking CUDA error and Torch error, makes no sense, online no one agrees and 0 answers again
> Try again but this time on a clean machine
> Still no go
> Last resort, use the docker image they themselves provided of flownet
> Same fucking error
> While in the process of debugging, realize my training image set is also bound to have bad results because "directly concatenating" images together as they claim in the paper actually has horrible results, and the network doesn't accept 6 channel input no matter what, so the only way to get around this is to make 2 images (3 * 2 = 6 quick maths)
> Fix my training data, fuck Nvidia dude who gave me wrong info
> Try again
> Same fucking errors
> Doesn't give nay helpful information, just spits out a bunch of fucking memory addresses and long function names from the CUDA core
> Try reinstalling and then making a basic torch network, works perfectly fine
> Setup vid2vid and flownet again
> SAME FUCKING ERROR
> Try to build the entire network in tensorflow
> CUDA error
> CuDNN version mismatch
> Doesn't work with TF
> HAVE TO FUCKING DOWNGEADE DRIVERS TOO
> TF doesn't support latest cuda because no one in the ML community can be bothered to support anything other than their own machine
> After setting up everything again, realize have no space left on 75gb machine
> Try torch again, hoping that the entire change will fix things
At this point I'll leave a space so you can try to guess what happened next before seeing the result.
> SAME FUCKING ERROR
In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.
If anyone has vid2vid working or has gotten around the kernel image error for AWS K80s please throw me a lifeline, in exchange you can have my soul or what little is left of it5
Client : We have performance issues on <this> page.
US : Testing with their data on : Xeon : All good, Core i7 : all good, Core i5 : all good, A smartphone : all good, core i5 UM version from 5 years ago (You know, 1.8Ghz, 2 cores, not 4) : all good.
US : Could you share your screen and show us ?
Client : Sure ! Shares his screen. Chrome is already opened. Refreshes the page, after 15 seconds, chrome : Would you like to stop script on this page ?”
US with mic on mute : “WTF?! It cannot happen here. It’s only a list of about 500 rows!”.
US : “Hello, could you open a tasks manager?”
Client : “ Sure, but I need to do it through here”
Some random VID interface popping up. Opens tasks manager with a beautiful “48 vCPUs detected”.
I have no idea how their virtualization is settled, but it seems to be messed up. Tomorrow going to be fun. I have a call at 9am to explain them their problem. Their IT will hate me forever.
If anyone has tips on Chrome through virtualization, please tell me.
EDIT : Yes 48. Not 4-8. It's not an error6
I was part of a on-call rotation. We had ~800 microsites with decent traffic on this one box, because that's a good idea...
One day the box was experiencing kernel panics and causing core dumps. After exhausting every possiblity I decided it was time to restart the box:
sudo shutdown now
Missed the -r and the box was not accessible remotely. Had to wait for someone at the data center to terminal in.
Downtime was ~2 hours.
This was caused by a crontab that automatically ran apt-get update & apt-get upgrade... Also made by me... None of this should have worked or allowed to be done!
This whole experience thing is really killing me.
"We like you a lot and you seem to have a solid understanding of the core concepts but you just lack the experience we need"
I've heard that basic response from plenty of different potential employers. Granted they could be lying just to be nice but that doesn't help the situation either.
Like tell me where I am lacking and where to improve.
Yea I can learn on my own but they're a lot of things I will never think about touching or gain any knowledge of because it's not something I may ever need to dive into during just everyday apps. There is a difference in building a hobby app to learn and what goes into a full blown application handling thousands of users and all the data that can come along with it. Not to mention the kind of things that can go wrong when you have thousands of users on your app at the same time all doing different things. That's not something I can just have experience with. If I could just get in somewhere I can prove myself because then I will be doing it each and everyday.
Gotta keep grinding though, I'll get something eventually.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.23
After a few weeks of being insanely busy, I decided to log onto Steam and maybe relax with a few people and play some games. I enjoy playing a few sandbox games and do freelance development for those games (Anywhere from a simple script to a full on server setup) on the side. It just so happened that I had an 'urgent' request from one of my old staff member from an old community I use to own. This staff member decided to run his own community after I sold mine off since I didn't have the passion anymore to deal with the community on a daily basis.
O: Owner (Former staff member/friend)
D: Other Dev
O: Hey, I need urgent help man! Got a few things developed for my server, and now the server won't stay stable and crashes randomly. I really need help, my developer can't figure it out.
Me: Uhm, sure. Just remember, if it's small I'll do it for free since you're an old friend, but if it's a bigger issue or needs a full recode or whatever, you're gonna have to pay. Another option is, I tell you what's wrong and you can have your developer fix it.
O: Sounds good, I'll give you owner access to everything so you can check it out.
Me: Sounds good
*An hour passes by*
O: Sorry it took so long, had to deal with some crap. *Insert credentials, etc*
Me: Ok, give me a few minutes to do some basic tests. What was that new feature or whatever you added?
O: *Explains long feature, and where it's located*
Me: *Begins to review the files* *Internal rage wondering what fucking developer could code such trash* *Tests a few methods, and watches CPU/RAM and an internal graph for usage*
Me: Who coded this module?
O: My developer.
Me: *Calm tone, with a mix of some anger* So, you know what, I'm just gonna do some simple math for ya. You're running 33 ticks a second for the server, with an average of about 40ish players. 33x60 = 1980 cycles a minute, now lets times that by the 40 players on average, you have 79,200 cycles per minute or nearly 4.8 fucking cycles an hour (If you maxed the server at 64 players, it's going to run an amazing fucking 7.6 million cycles an hour, like holy fuck). You're also running a MySQLite query every cycle while transferring useless data to the server, you're clusterfucking the server and overloading it for no fucking reason and that's why you're crashing it. Another question, who the fuck wrote the security of this? I can literally send commands to the server with this insecure method and delete all of your files... If you actually want your fucking server stable and secure, I'm gonna have to recode this entire module to reduce your developer's clusterfuck of 4.8 million cycles to about 400 every hour... it's gonna be $50.
D: *Angered* You're wrong, this is the best way to do it, I did stress testing! *Insert other defensive comments* You're just a shitty developer (This one got me)
Me: *Calm* You're calling me a shitty developer? You're the person that doesn't understand a timer, I get that you're new to this world, but reading the wiki or even using the game's forums would've ripped this code to shreds and you to shreds. You're not even a developer, cause most of this is so disorganized it looks like you copy and pasted it. *Get's angered here and starts some light screaming* You're wasting CPU usage, the game can't use more than 1 physical core, and after a quick test, you're stupid 'amazing' module is using about 40% of the CPU. You need to fucking realize the 40ish average players, use less than this... THEY SHOULD BE MORE INTENSIVE THAN YOUR CODE, NOT THE OPPOSITE.
O: Hey don't be rude to Venom, he's an amazing coder. You're still new, you don't know as much as him. Ok, I'll pay you the money to get it recoded.
Me: Sounds good. *Angered tone* Also you developer boy, learn to listen to feedback and maybe learn to improve your shitty code. Cause you'll never go anywhere if you don't even understand who bad this garbage is, and that you can't even use the fucking wiki for this game. The only fucking way you're gonna improve is to use some of my suggestions.
D: *Leaves call without saying anything*
TL;DR: Shitty developer ran some shitty XP system code for a game nearly 4.8 million times an hour (average) or just above 7.6 million times an hour (if maxed), plus running MySQLite when it could've been done within about like 400 an hour at max. Tried calling me a shitty developer, and got sorta yelled at while I was trying to keep calm.
Still pissed he tried calling me a shitty developer...
I think I have multiple but this guy stands out.
He was a fellow student at my software development study. Used primarily FOSS systems/software, not because he cared about ethics as much but because that way he could tinker with the software as much as he wanted.
He was always searching for new things to tweak, write, explore and so on. And he shared as much as he could with fellow students.
A few examples of what he did:
- wanted to change something about how Linux worked at its core (he mainly used debian based systems) so he learned how to write kernel modules and wrote his solution.
- wanted to be able to monitor his gas/power usage so he hacked an arduino thing into the power/gas meter and got it to send updates to a messenger at command.
- setup and automated mini data center because fuck it, fun to do.
His thinking was always very creative and to this day I still appreciate what he taught me on that!4
I’ve found a variant of a variant of Mirai in a client’s server, tried to remove it, failed, shut off the server and disconnected it.
The server was our ownership but was situated at the client’s building in their network.
We asked for this server to be in a DMZ segregated from the actual production network just because in the production network there’s the core business as well as credit card data.
They failed to implement our requests and they got hacked.
I hope I discovered the threat in time, but I’m quite sure some head will fall off.
Hell, I’m sorry for those guys but I love my job ❤️
I traced back the malware maker/s and dumped their VPS just because.2
Hi! I'm new in freelancing. I've created a program that scrapes data from a website, parses it, runs DB queries, and emails the prepared data to the customer for whom I've created this program. The whole program is written in PHP and uses a MySQL table. There's almost no front-end, it's just like an automated background process that runs with a cron job. I've bought and set up a domain and hosting for them (my cutomer paid it all). I got the core part of the program running after ~2 days, and it took me ~a week to complete the project including adding features and the testing phase. Now, I'd like to know, how much does this kind of project cost? The business operates in Silicon Valley.10
I once agreed to maintain and develop an application used in a different section of the school to keep inventory and make sure everything is where it is supposed to be.
At first there was enthusiasm, together with 2 of my classmates we agreed and git clone-d the .NET application that now graduated students built and maintained for the past few years. What could go wrong right?!
It became clear that the original students that worked on it followed an older curriculum, meaning they still got taught .NET instead of the core variant that we get now, not only that but it also seemed that they either did not fully grasp the Clean/Onion architecture or didn't get it in class since there were infrastructure components in the 'Domain' project of the solution. Think of 2 DBContexts in the domain model, yep.
One of us bailed in the first week, the other one and I felt bad for the people using the app so we went on and tried to work on the first bugs that were described in a document. One of these bugs was 'whenever I filter on something in the list, everybody gets to see that filter on their screen instead of only me'. Woah that's weird! Let's see how they put that together!
Oh god, they are using a _static_ variable to store filters, no wonder that it doesn't work properly. Ever heard of sessions?!
Second bug: Sometimes people can't create an account when we sign them up from the admin panel. Alright that is weird, let's figure that one out! Wait a second it seems to work in development? What's this about.
Oh wait I can't create an account on production either? Oh that's weird, wait a second... Why do I have to put my e-mail in a form that was sent to me through e-mail? Why is my address not filled in already? OOH, if someone types in the wrong e-mail address (which is easy since our school has 4 variants of the same f*cking e-mail address) it won't work since it can't recognize the user! Brilliant! Remove e-mail input box and make a token/queryparam determine the user account.
Ah that seems good, it's a mess but it seems a tiny bit better now, great! We're making progress and some sweet buck.
Next bug, trillions of 50x errors on random pages, that's a weird one.
Hm everything works in development, that's odd. Is the production data corrupted?
DID I MENTION that in order to get into the system in development we have to load in a f*cking production database backup ON OUR DEVELOPMENT MACHINE and then ask one of the users' password to login to it and create an account for ourselves? Seeding? What's that, right?!
Anyway, back to bug fixing. I e-mail the the people responsible for the app and get a production admin account, oh I also can't ssh into it because of policies so I have to do everything over e-mail and figure out what's causing the errors. I somehow also wonder if they have any kind of virtualization in place, giving students a VM to do that stuff in doesn't seem so weird does it ? Even with school policies?
Oh btw, 'deploying' means sending a .zip file to a guy in another building and telling him how to configure it, apparently this resulted in a missing folder that the application needed to work and couldn't make on its own. This after 2 weeks of e-mailing back and forth.
After 3 months i quit out of despair and sadness, and due to the fact that I just couldn't do it anymore. I separated everything into logical subprojects and let the last guy handle it, he was OK with that and understood why I left.
Luckily, around that time I already had an actual job at a software development company :)1
Is your code green?
I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.
I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?
* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.
Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.
I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.
In terms of cycles that can be the difference between needing a single core and a thousand cores.
This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.
Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.
I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.
I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.
I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.
The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.6
There are a couple of them to list! But to sum my main ones(biggest personal heroes):
John McCarthy, one of the founding fathers of Artificial Intelligence and accredited with coining such term(sometimes before 1960 if memory serves right), a mathematical prodigy, the man based the original model of the Lisp programming language in lambda calculus. Many modern concepts that we have in programming where implemented in one way or another from his systems back in the day, and as a data analyst and ML nut.....well I am a big fan.
Herb Sutter: C++ programmer extraordinaire. I appreciate him more for his lectures and published articles than anything else. Incredibly smart and down to earth and manages to make C++ less intimidating while still approaching it with respect.
Rich Hickey: The mastermind behind Clojure, the Lisp dialect for the JVM. Rich is really talented and his lectures behind his motivations and reasons behind everything he does with Clojure are fascinating to see.
Ryan Dahl: Awww shit y'all know how it is. The man changed web development both in the backend and the frontend for good. The concept of people writing their own servers to run their pages was not new, but the Node JS runtime environment made it more widely available to people by means of a simple to use language that was already popular with web developers. I would venture to say that Ryan's amazing contributions to JS made the language better, as it stands, the language continues to evolve and new features that make it overall better keep being added. He is currently building Deno, which would be a runtime environment for TypeScript, in Rust.
Anders Hejlsberg: This dude was everywhere man....the original author of Turbo Pascal and the lead of Delphi back in the day. These RAD tools paved the way for what would be a revolution in the computing world. The dude is also the lead architect and designer of the C# programming language as well as TypeScript.
This fucker is everywhere and I love it.
Yukihiro "Matz" Matsumoto: Matsumoto san is the creator of the Ruby programming language. Not only am I a die hard fan of Ruby, but of the core philosophies that the man keeps as the core of his language design: Make the developer happy, principle of least surprise. Also I follow: minswan which is a term made by the Ruby community that states Mats is nice so we are nice. <---- because being cool to others is better than being a passive aggressive cunt.
Steve Wozniak: I feel as if the man does not get enough recognition...the man designed the Apple || computer which (regardless of how much most of y'all bitch and whine) paved the way for modern micro computers. Dude is also accredited with designing one of the first programmable universal remotes(which momma said was shitty) but he did none the less.
Alan Kay: Developed Smalltalk and the original OOP way of doing things. Smalltalk as a concept is really fucking interesting. If you guys ever get the chance, play with Pharo, which is a modern Smalltalk. The thing is really interesting and the overall idea of Smalltalk can be grasped in very little time. It sucks because the software scales beautifully in terms of project building, the idea of hoisting a program as its own runtime environment and ide by preserving state through images is just mind blowing to me. Makes file based programs feel....well....quaint.
Those are some of the biggest dudes for me. I know that the list is large, but I wanted to give credit to the people that inspired me the most. Honorary mention goes to other language creators and engineers of course, but it would be way too large to list!9
Hey guys it's not a rant, but i feel this place might help...
I am a 20 yr old, second year guy ...have got some experience in core Java and after that, i have been doing android for 8months... Yeah , i coded some basic apps got my hands dirty on firebase, sql libraries and some connectivity...
Even got landed in an internship.
Today i feel myself to be an intermediate android dev , nd i know their are many things that can be learnt in android that i don't know..
But what after that?development as a carrier interests me, but i fear for a job security ... I could learn more of Android,maybe learn ios after that but their are always articles coming out that react is future, webapps will replace android and stuff like that...
I Have also heard stuff like companies today want to squeeze more out of their techs, so they want less and complete developers having experience in both web and mobile app designing and other stuff like that
Are you freakin kidding me? Android and ios alone are like drinking Pacific and indian ocean and to add web developing, its like drinking out every drop of ocean in the world.
I guess their are guys which exist with knowledge of all three, maybe I can cover them all too(someday) but that would take my whole clg life of 4 years..(I guess)
And no ,I don't have problems with that too.. I actually like developing but again i hear big words like cloud computing, AR,VR AI, data sciences, automation, graphics designing, game dev, and many more...
Basically i hear too much and i fear too much 😅 and i don't think closing my ears would be a good choice...
So, which ocean of carrier should i aim to go for?nd are my fears real? Do companies really prefer some web guy designing Amazon like apps over android-only guys like me?is automation nd templates really gonna take all we, developers jobs?should i look into ai/data sciences?
Well , i am a simple guy, who got his first pc at 17 so naturally, i am fascinated even by the working of a calculator app and anything relates to tech so am open to pursue my interests in any fields23
Oh I have quite a few.
#1 a BASH script automating ~70% of all our team's work back in my sysadmin days. It was like a Swiss army knife. You could even do `ScriptName INC_number fix` to fix a handful of types of issues automagically! Or `ScriptName server_name healthcheck` to run HW and SW healthchecks. Or things like `ScriptName server_name hw fix` to run HW diags, discover faulty parts, schedule a maintenance timeframe, raise a change request to the appropriate DC and inform service owners by automatically chasing them for CHNG approvals. Not to mention you could `ScriptName -l "serv1 serv2 serv3 ..." doSomething` and similar shit. I am VERY proud of this util. Employee liked it as well and got me awarded. Bought a nice set of Swarowski earrings for my wife with that award :)
#2 a JAVA sort-of-lib - a ModelMapper - able to map two data structures with a single util method call. Defining datamodels like https://github.com/netikras/... (note the @ModelTransform anno) and mapping them to my DTOs like https://github.com/netikras/... .
#3 a @RestTemplate annptation processor / code generator. Basically this dummy class https://github.com/netikras/... will be a template for a REST endpoint. My anno processor will read that class at compile-time and build: a producer (a Controller with all the mappings, correct data types, etc.) and a consumer (a class with the same methods as the template, except when called these methods will actually make the required data transformations and make a REST call to the producer and return the API response object to the caller) as a .jar library. Sort of a custom swagger, just a lil different :)
I had #2 and #3 opensourced but accidentally pushed my nexus password to gitlab. Ever since my utils are a private repo :/3
-- This is my first rant so sorry if it's bad--
We have a nice project that I am working on that needs to store and interact with location data. It is a .NET Core API using Entity Framework Core to interact with the database. All good and well. Until today when I started working on the implementation of storing location data we retrieve from mobile devices.
SQL has a nice data type named: "Geography" which can store a location and do calculations on it with queries. Such as proximity and distance which is what we need.
But then it turns out that EntityFramework Core does not have support for the Spatial data types. even though version 6 did have Spatial support.
Then i found the following issue on GitHub: https://github.com/aspnet/...
Turns out this feature has been requested since 2014 and is even on the "High-priority" list and is still not implemented to this day. Even though in the issue many people are asking to have this implemented.
WHY IS THIS TAKING SO LONG MICROSOFT!!
So now i have to figure out how to work around this. But that is an issue for tomorrow.1
Can someone help me understand?
I subscribed to a nifty IT-releated magazine, and on its back, there's an ad for "Dedicated root server hosting", nothing unusual at a first glance, but after I read the issue, I decided to humor them and see what it is that they offered, and... It just... Doesn't make sense to me!
An ad for "Dedicated Root Server" - What is a dedicated root server first of all? Root servers of any infrastructure sound pretty important.
But, the ad also boasts "High speed performance with the new Intel Core i9-9900K octa-core processor", that's the first weird thing.
Why would anyone responsible enough want to put an i9 into a highly-reliable root server, when the thing doesn't even support ECC? Also, come on, octa-core isn't much, I deal with servers that have anywhere between 2 and 24 cores. 8 isn't exactly a win, even if it has a higher per-core clock.
Oh, also, further down the ad has a list of, seeming, advantages/specs of the servers, they proclaim that the CPU "incl. Hyper-Threading-Technology"... Isn't that... Standard when it comes to servers? I have never seen a server without hyperthreading so far at my job.
"64 GBs of DDR4 RAM" - Fair enough, 64 gigs is a good amount, but... Again, its not ECC, something I would never put into a server.
"2 x 8 TB SATA Enterprise Hard Drive 7200 rpm" - Heh, "enterprise hard drive", another cheap marketing word, would impress me more if they mentioned an actual brand/model, but I'll bite, and say that at least the 7200 rpm is better than I expected.
"100 GBs of Backup Space" - That's... Really, really little. I've dealt with clients who's single database backup is larger than that. Especially with 2x8 TB HDD (Even accounting for software raids on top)
This one cracks me up - "Traffic unlimited"
Whaaaat?! You are not gonna give me a limit to the total transferred traffic to the internet for my server in your data center? Oh, how generous of you, only, the other case would make the server just an expensive paperweight! I thought this ad was for semi-professionals at least, so why mention traffic, and not bandwidth, the thing that matters much more when it comes to servers? How big of a bandwidth do I get? Don't tell me you use dialup for your "Dedicated Root Server"s!
"Location Germany or Finland" - Fair enough, geolocation can matter when it comes to latency.
"No minimum contract" - Oooh, how kiiiind of you, again, you are not gonna charge me extra for using the server only as long as I pay? How nice!
"Setup Fee £60" - I guess, fair enough, the server is not gonna set itself up, only...
The whole ad is for "monthly from £55.50", that's quite the large fee for setup.
Oh, and a cherry on top, the tiny print on the bottom mentions: "All prices exclude VAT and are a subject to..." blah blah blah.
Really? I thought that this sort of almost customer deceipt is present only in the common people's sphere!
I must say, there's being unimpressed, and then... There's this. Why, just... Why? Anyone understands this? Because I don't...12
Android development is unnecessarily complex. To the core. Rant #371651681324
Only being few months in to android development, I can say that using too many functions and classes for doing something silly is very illogical. I mean -
Livedata, think about it, if some data is shown on the UI, it must mean the UI be updated instantly on data change, but the concept of Livedata was introduced only few years back.Which again, needs an observer and we actually have to ask it to observe changes.
Android development is a mess. More and more updates to the architecture and code is to cover up the problems that shouldn't have existed in the first place. A simple Spinner with custom object will require more time in stackoverflow rather than actual coding. Very counter-intuitive, inefficient, time-consuming and exhaustive.5
Core library was giving serious blow out of execution speed as data file size increased.
Traced it back to a GetHashCode implementation that was giving too many collisions for unequal objects, so when used as the key in a hash table it was causing the lookup to fall back to checking Equals (much slower).
Improved the GetHashCode implementation, and also precalculated it on construction (they were immutable objects), and run time went to warp speed! Was very happy with that.
Obviously put in a thread sleep to help manage expectations with the boss/clients going forwards. Can’t give those sort of gains away in one go. Sets a dangerous precedent.1
Hey guys, wanna install Linux first time, but had some doubts.
Config - core 2 duo 2.93GHz, 2GB ddr2 ram, 320 hdd, AMD graphics card.
1. After writing it on usb and setting it in usb boot mode, the system didn't read the pen drive data ... is it because of the writing software ... I used power iso.
2. What about the partitions ? Do they still remain and will the install guide only ask to format the c drive or the whole hdd ?
3. Which distro do y recommend... I had kali/debian/fedora/mint in mind
My friends complained about fedora taking 45 seconds to boot up, I don't know about the other distro's ..
Thanks in advance10
So we work on a Vmware network. And besides the terrible network lag. The specs of that VM is one core (Possibly one thread of a xeon core) and 3 GB RAM.
What do we do on it?
Develop heavy ass java GUI applications on eclipse. It lags in every fucking task. Can't even use latest versions of browsers because the VM is a fucking snail ass piece of shit!
So, in the team meeting I proposed to my manager, Hey our productivity is down because of this POS VM. Please raise the specs!.
He said mere words won't help. He needs proof.
Oh, you need proof ? Sure. I coded up a script that all of my team ran for a week. That generates a CSV with CPU usage, mem left, time - every 10 min. I use this data to show some motherfucking Graphs because apparently all they understand is graphs and shit.
So there you go. Have your proof! Now give me the specs I need to fucking work!3
How are Coding Bootcamps and what are they like?
A little background:
I’ve been going to a University (have a year left for a CS degree) and I am so EXTREMELY frustrated. I thought I would get an education but it’s so underwhelming. 95% of it doesn’t involve programming and the classes that do are so elementary that I know more than the professors. By the end of my web design course we had been taught to center text, insert images, insert links, and how to use tables with a single day on CSS using colors.
The OOP courses are all the same, learn variables, types, conditionals, loops, classes, functions, and so forth. Python, C++, and Java. I taught all this to myself when I was 15, I’m 29 now.
I’ve recently gotten extremely interested into full stack web development. .NET Core, React, Typescript. I’m also working with Electron. I’m basically 100% self taught and spend almost every waking moment trying to learn more and apply it.
There’s only one person at my school who has the same passion as me and he’s the president at the coding club but is going into machine learning and big data (I’m the Secretary) and I just wish I could interact with more people who have the same passion. I would love to be challenged. I feel as if I spend more time trying to learn and diagnose problems then applying my knowledge because web development is so complicated when it comes to connecting everything together and I’m still relatively new to it (started like 4 months ago). I’m an extremely fast learner and extremely dedicated so I’m not worried about that being an issue.
I just really want to be a part of a community where I have people who can answer my questions and I don’t have to spend hours or days on google finding a solution to integrating Webpack or using typescript with react, and more. I want to feel challenged.
Can I get this from a boot camp? I recently listened to a podcast from Syntax and it really excited me but I don’t want to be let down again. Either way I’m finishing my degree to get that bullshit $60000 piece of paper but I wouldn’t mind taking a couple months off for something like this if it’s worth it.
I live in CO so if you have any Bootcamps in CO that you recommend, I’d love to hear it and take a trip to check it out in person.
Thanks a bunch!11
Worst thing? Absuse LINQ and not in a fun sexy way.
Entity framework > check.
LINQ query > check.
Standard IEnunerable magic > check
The developer had decided that it would be a good idea to thread the enumerable all over the place and collapse it anytime they wanted access to the data.
I know it’s a rookie mistake a lot of people make, but it was some pretty core data that ended up being used all over the place, so it was a nightmare to correct and it really impacted performance.
Needless to say they felt very silly when we explained how LINQ was deferred.
Story about my old boss:
I was doing a lot of work in an area that had a data property and a method to build an object. I noticed a reset method that iterated all that objects properties, found the matching data from the data object, passed that data through some logic to format it and then assigned that value to the object property.
As part of my PR I removed that method, since data wasn't changing, and simply called the create method again with data.
The result of tidying the code base and putting it up for review before a merge? I get told I have no respect for my boss's code, that I am undermining him, that I need to be more considerate and respectful of other people's work and that I am no longer allowed to change any code he has written in the code base (half the code base) without talking to him about it first, before it goes up for review. Also if he is working on an area I cannot change anything - not even 1 character (he is working on the core of the app).
Every day there I was so confused :D8
I'm starting to feel super frustrated with my job.
Sometimes I feel like people who work for large tech companies must have it easy. My company is trying to do this digital transformation thing. Modern development practices Scrum, agile, CI/CD etc. So I was put on a team to work on a project with this new methodology. The idea was we would build the front end and interface with the core systems via service calls. Of course it didn't work out that simple and we had to add our own server side stuff but whatever. It's really hard without a point of reference for any of this stuff. We don't have established coding standards, the data we are working with is a mess, incompetent vendors, the infrastructure team supporting the environments can be such arrogant fucks when we need their help to get shit done. The team also doesn't have any members who really know the core systems well. I am the only developer on the team who is an employee of the company the rest are contractors who are in and out. Last week it was literally just me. This is my first job out of school btw I've been here a year now. I guess I just feel frustrated that I have to figure out so much on my own I don't really have many senior devs at the company I can look to. And on the team I've sorta ended up in an unofficial leadership position. Feels like a lot on my shoulders. I feel like if i could have worked for a bigger company I could learn to do a lot of things better. I feel like there's too much on me for the amount of experience I have or am I wrong ?5
The past few months i got a bunch of emails and calls from my previous "boss" (hes the head of the research), that he would be grateful if i helped them out. I got a few friends still working on that piece of shit project so i said yeah, i can help.
Now this whole thing is a research involving most of the big universities, lots of math phds, and is kinda secret. They couldnt find anyone to sketch up a few stupid algorithms for them so i did just that.
Yesterday i got the specifications for the task. Its the core functioning algo, the one i made from fucking discrete integer data, it took me 3 fucking months to correct their mistakes, and now they want me to create 2 similar patterns for 2 completely different...things. Yeeeah no.3
So we’ve taken over from a project team that disbanded... read: “cut their contracts because fuck this, I can earn more working for better people”.
Me and one other guy have been tasked with saving this heap of shit.
Obviously the project guys left saying “it’s nearly done, just this one feature”. Because cut contracts are easier to deal with if “everything is almost done”.
We jump on and find that’s not the case at all... this thing, is a beast, a big old stats analysis program... so we’re like “cool, let’s see what’s going o...OH MY GOD”.
The “recalculation” function was core to this POS. The contractors had done it in C# through entity framework... it took 24 hours to run, over a reasonably small data set that was due to double every 2-5 years.
So... here’s the deal, it ran over night.... then failed. And no cunt had noticed. Entity framework “can’t commit because I’m muddled up as fuck, did you really just put the whole db in EF in memory to work with it?” Exception.
Que 6 months of me and my lead doing the job properly.
Anyway, the failure: I ended up in Hospital again with a Crohn’s flare up... about 5 months in.
Fuckall to do with all this nonsense I just wanted to tell a story. it was an interesting/fun project to fix and my lead was a legend... so happy days.
Similar story, different set of contracted devs... they’d been defining requirements with the business users using the term “Risk” which the business users knew as a group of risks.
The domain model had been written RiskGroup<>—
Yesterday we released this huge refactoring/rewrite I did alone so it was my task to release and fix any upcoming problems. Not that I would have died to refactor a huge part of the codebase but technical debt was waiting to kill us on upcoming features.
Deployment is done by ssh'ing into prod and pulling from git. I'm happy I could convince them to track a dedicated release branch... Why would we want to build anything? What is automation?
Debian 8 with MySQL 5 community edition... Throws some internal error on my use of JSON functions. Thankfully I was allowed to switch prod to MariaDB but updating packages caused segfaults with the PHP MySQL connector. This is why you need NixOS!
Prod is a 4 core 4 GB VM that would take forever to run migrations. Also no disk space. Had to copy the whole db to staging (which is much more powerful and on Debian 9? diverging environments in the same data center...), migrate there and and pipe back mysqldump directly into ssh while in my neck I feel another client's project that I have about half a week left to finish.
It's Monday night. Customer has a full office of over 50 users at 8 AM.
Almost fell asleep in the car the next day, and I think I have RSI in my enter finger now.
Nice to do some refactoring of the whole data access layer of our core logistics software, let me tell an story.
The project is around 80k lines of code, with a lot of integrations with an ERP system and an sql database.
The ERP system is old, shitty api for it also, only static methods through an wrapper to an c++ library
imagine an order table.
To access an order, you would first need to open the database by calling Api.Open(...file paths) (yes, it's an fucking flat file type database)
Now the database is open, now you would open the orders table with method Api.Table(int tableId) and in return you would get an integer value, the pointer.
Now for the actual order. first you need to search for it by setting the search parameter to the column ID of the order number while checking all calls for some BS error code
Api.SetInt(int pointer, int column, int query Value)
Then call the find method.
Then to top this shitcake of an api of: if it doesn't find your shit it will use the "close enough" method of search.
And now to read a singe string 😑
First you will look in the outdated and incorrect documentation given to you from the devil himself and look for the column ID to find the length of the column.
Then you create a string variable with ALL FUCKING SPACES.
Now you call the Api.GetStr(int pointer, int column, ref string emptyString, int length)
Now you have passed your poor string to the api's demon orgy by reference.
Then some more BS error code checking.
Now you have read an string value 😀
Now keep in mind to repeat these steps for all 300+ columns in the order table.
News from the creators: SQL server? yes, sql is good so everything will be better?
Now imagine the poor developers that got tasked to convert this shitcake to use a MS SQL server, that they did.
Now I can honestly say that I found the best SQL server benchmark tool. This sucker creams out just above ~105K sql statements per second on peak and ~15K per second for 1.5 second to read an order. 1.5 second to read less than 4 fucking kilobytes!
Right at that moment I released that our software would grind to an fucking halt before even thinking about starting it. And that me & myself and I would be tasked to fix it.
4 months later and two weeks until functional beta, here I am. We created our own api with the SQL server 😀
And the outcome of all this...
Fixes bugs older than a year, Forces rewriting part of code base. Forces removal of dirty fixes. allows proper unit and integration testing and even database testing with snapshot feature.
The whole ERP system could be replaced with ~10 lines of code (provided same relational structure) on the application while adding it to our own API library.
Best part is probably the performance improvements 😀. Up to 4500 times faster and 60 times less memory usage also with only managed memory.3
Oh god where do I start!?
In my current role I've had horrific experiences with management and higher ups.
The first time I knew it would be a problem: I was on a Java project that was due to go live within the month. The devs and PM on the project were all due to move on at the end. I was sitting next to the PM, and overheard him saying "we'll implement [important key feature] in hypercare"... I blew my top at him, then had my managers come and see if I was OK.
That particular project overran with me and the permanent devs having to implement the core features of the app for 6mo after everyone else had left.
I've had to be the bearer of bad news a lot.
I work now and then with the CTO, my worst with her:
We had implemented a prototype for the CEO of a sister company, he was chuffed with it. She said something like "why is it not on brand" - there was no brand, so I winged it and used a common design pattern that the CEO had suggested he would like with the sister company's colours and logo. The CTO said something like "the problem is we have wilful amateurs designing..." wilful amateurs. Having worked in web design since I was 12 I'm better than a wilful amateur, that one cut deep.
I've had loads with PMs recently, they basically go:
PM: we need this obscure set up.
Me & team: why not use common sense set up.
PM: I don't care, just do obscure set up.
The most recent was they wanted £250k infrastructure for something that was being done on an AWS TC2.small.
Also recently, and in another direction:
PM: we want this mobile app deploying to our internal MDM.
Us: we don't know what the hell it is, what is it!?
PM: it's [megacorp]'s survey filler app that adds survey results into their core cloud platform
Us: fair enough, we don't like writing form fillers, let us have a look at it.
*queue MITM plain text login, private company data being stored in plain text at /sdcard/ on android.
Us: really sorry guys, this is in no way secure.
Pm: *in a huff now because I took a dump on his doorstep*
I'll think of more when I can.
fuck the guy that writed the api that I consume at my company
he's not the worst guy ever, and he might be going through some stuff in life, or maybe he's just happy. There's no way to know actually.
but fuck him. fuck this fucking guy. fuck him with a thousnd dicks.
this guy defends his postures on the api like this thing was fucking sacred and masterly designed ok?
if I ask him to change one url's method from get to post so that I can send more longer data for the request, he comments "i cant believe they still haven't figured out a get request with a body". I appreciate him caring abkut the correctness.
but this is the same piece of shit that makes NOOO fucking validations on whatever I send to it. I get 500 for fucking EVERYTHING.
And if he does 400, the actual response messages are garbage, the same fucking text with no explanation.
I hate the way he structures the names of the url and the parameters, sometimes I have to send arrays of strings, other times arrays of objects, the naming is garbage and INCOSISTENT.
And when we asked him to do the API dotnet core, he was like "nah" FUCK YOU FOR USING SOON TO OBSOLETE TECHNOLOGIES!!!
THIS PIECE OF SHIT IS SLOW, because a coworker did another spi in core and the response times are hugely better.
I wouldnt mind if he was 100% of the time careless, but he actually makes a stand for his ideas, as if he actually gave two shits.
he's actually an ok guy though but... fuck hiim!!!! ive been holding onto this for a while... and I'm sure I have some flaws too.9
So this web company i joined had a page load time in minutes. The free text search (inverted index search, based on elasticsearch) queries would return results in 10-45 seconds (should be milliseconds always). The indexes had no schema. And they would crawl data and feed into mssql db, which had a 2 gb/db limit on the free version. So everytime the db hit the limit, a new db was created and the name was incremented by one.
Had a very tough time cleaning up that mess. Plus the architect who had made this architecture was on his way out and unhelpful to the core.
What was worse was that most of the changes i did were very simple changes that should have been done long back. Basic sanity changes.4
Ok, so I need some clarity from you good folk, please.
We have had a number of chats about what I am best focusing on, both personally and related to work, and he makes quite a compelling case for the "learn as many things as possible; this is what makes you truly valuable" school of thought. Trouble is, this is in direct contrast to what I was taught by my previously esteemed mentor, Gordon Zhu from watchandcode.com. "Watch and Code is about the core skills that all great developers possess. These skills are incredibly important but sound boring and forgettable. They’re things like reading code, consistency and style, debugging, refactoring, and test-driven development. If I could distill Watch and Code to one skill, it would be the ability to take any codebase and rip it apart. And the most important component of that ability is being able to read code."
As you can see, Gordon always emphasised language neutrality, mastering the fundamentals, and going deep rather than wide. He has a ruthlessly high barrier of entry for learning new skills, which is basically "learn something when you have no other option but to learn it".
Any thoughts, people? I would be interested to hear peoples experiences regarding depth vs breadth when it comes to the real world.8
The codebase Im working with is like someone took 3 sets of earphones, crumpled them together in their pocket, and then threw them into a bag full of spaghetti and wasps. Too confusing to comprehend and dependencies absolutely everywhere. All I have to do is port over a relatively straightforward piece of functionality from one iOS app to another. Core Data has other plans it seems....
So I did this https://devrant.io/rants/797965/... which works fine until medium sized data.
However for large data the ETL pegs a 6 core Xeon (2.2GHz) with 50GB of ram. Because of it ends up doing six threaded compares, so 12 different data sets. Other than "pull less data", any tips?
Code (C#) is basically a Linq multi column join between two DataTables and when the compared columns don't match it returns as a var which is turned into a third DataTable to be SqlBulk loaded into the DB.
Table1 is external API return data (no windowing) and Table2 is from our DW.7
Out of the frying pan, into the fire:
So in my first job, I thought it's just us operating so crazy: meddling with arcane C/C++ code from the 80's, shooting our code to production without testing, fixing hundred of customers data base entries by hand, letting an intern alter some core component (to have more logging) and directly push it to prod...
I mean I suspected, that maybe it's not only this tiny little company acting wild, that also the bigger companies with all their ISO certified processes, agile blabla, professional tooling whatsoever - will also have their skeleton in the closet,.. like some obscure assembler part buried in the heart of your code base nobody dares to touch...
How Pieter Hintjens asked about the state of the industry and all the fads so bluntly put it:
"It's all bullshit."
But we are humans, so we better jump on the bandwagon if we want to keep our jobs... and somehow try to keep that trashy house of cards from crashing down.
New "senior" mobile developer started the other day, doesn't know what core data is or the best way to implement a network call. I'll just leave that there to sink in for a second.1
Keep going into application level timeouts and insufficient number of xml messages frames transmitted through tcp sockets.
Found that a "custom" C-written xml parser needs 10 seconds to find the core data within 2500 chars of that xml.
I knew that C is blazing fast but that's until it's used by some dick head.2
Got a new job in data processing. Took them a couple days to get me a laptop and two weeks after that to get the core programs I need to begin working. Found out today that I *still* don't have access to everything I need for my job.3
I work at company that uses Drupal for everything. And i mean EVERYTHING. Our dumb CTO once even wanted us to join tender for flight data collection system... of course it would run on fucking drupal...
Yeah i can see its advantages but it has learning curve the shape of the snail shell and if you want it to do something new you either find module for it or drupal will start crying, shits itself and tell you to go fuck yourself.. also it is full of surprises to make your day as miserable as possible, like you send variable as $content['varname'] to user template and it returns as $user_profile['varname']['value']... and yes user template has $content array for content but why use it for storing content that i want to render.. it is used for other content to render... because in drupal content != content...
I started using laravel for my freelance projects and it took my less than 2 week to get up to speed and start working and is incredible fast to work in... You know.. its fun when you want to just add feature you just code that feature into your app.. and not spend 2 fucking years crawling through retarded preprocess functions...
Whenever i try to suggest we use other frameworks.. "Muh drupal has MODULES".. yeah because drupal is the only thing in universe that has modules.. When client has only need for simple site with simple template why use wordpress and have it done in 2 days when you can use drupal have 10 000 unnecessary DB queries that drupal does on every page load to load page title and make that site in a week.. or why use laravel for e-shop with specific functionality requested by client that would take 2 weeks to add in laravel when you can spend 2 months modifing uber-cart or drupal commerce modules only to hit some Drupal core surprise that wont allow for that feature to be implemented...3
Sometimes I just wish Core Data would die.
I logged the managed object context of each object being touched and they're all identical. 😑😑😑😑😑😑1
1. Teach DS and Algos. Not basics but advanced data structures and the ones that are recently published.
2. DBMS should show core underlying concepts of how queries are executed. Also, what data structures are used in new tech.
3. Teach linkers, compliers and things like JIT. Parsers and how languages have implemented X features.
4. Focus on concept instead of languages. My school has a grad course for R and Java. (I can get that thing from YouTube !!)
5. Focus a little on software engineering design pattern.
6. It's a crime to let a developer graduate if he doesn't know GIT or any version control. Plus, give extra credits for students contributing to open source. Tell them if they submit a PR you get good grades. If that PR gets merged bonus (straight A may be ?)
7. Teach some design pattern and how industry write code. I am taking up a talk at school to explain SOLID design pattern.
Mostly make them build software!
Make them write code!
Make them automate their homeworks!
Make them an educated and employable student.!1

So to give you a feel for what evil, clusterfuck code it was in: this projects largest part was coded by a maniac, witty physicist confined in the factory for a month, intended as a 'provisional' solution of course it ran for years. The style was like C with a bit of classes.. and a big chunk of shared memory as a global mud of storage, communication and catastrophe. Optimistic or no locking of the memory between process barriers, arrays with self implemented boundary checks that would give you the zeroth element on failure and write an error log of which there were often dozens in the log. But if that sounds terrifying already, it is only baseline uneasyness which was largely surpassed by the shear mass of code, special units, undocumented madness. And I had like three month to write a simulator of the physical factory and sensors to feed that behemoth with the 'right' inputs. Still I don't know how I stood it through, but I resigned little time afterwards.
Well, lastly to the bug: there was some central map in that shared memory that hold like view of the central customer data. And somehow - maybe not that surprisingly giving the surrounding codebase - it sometimes got corrupted. Once in a month or two times a day. Tried to put in logging, more checks - but never really could pinpoint the problem... Till today I still get the haunting feeling of a luring memory corruption beneath my feet, if I get closer to the metal core of pure C.1
1) Had to fix severe bugs in a dynamic UI (configuration-driven forms) component.
Recognized undocumented Copy/Paste/Modify/FuckUp driven variations of the same component all over the project. Unsurprisingly, the implementations covered 99% of the antipattern catalog on wiki.c2.com and could compete with brainfuck in regard to human-readable code.
Escalated the issue, proposed a redesign using a new approach, got it approved.
Designed, Implemented, tested and verified the new shared and generic component. Integrated into the main product in the experimental branch. Presented to tech lead/management. Everyone was happy and my solution opened even more possibilities.
Now the WTF moment: the product with the updated dynamic UI solution never has been completely tested by a QA engineer despite my multiple requests and reminders.
It never got merged into baseline.
New initiatives to fix the dynamic UI issues have been made by other developers. Basically looking up my implementation. Removing parts they do not understand and wondering why the data validation does not work. And of course taking the credit.
2) back in 2013, boss wanted me to optimize batch processing performance in the product I developed. Profiling proved that the bottleneck ist not my code, but the "core" I had to use and which I must never ever touch. Reported back to him. He said he does not care and the processing has to get faster. And I must not touch the "core".
(FYI: the "core" was auto-generated from VB6 to VB.Net. Stored in SourceSafe. Unmaintainable, distributed about a bunch of 5000+ LoC files, eye-cancer inducing singlethreaded something, which had naive raw database queries causing the low performance.)
ok this may look like a lazy ass beginner crying out for spoon feeding( which it kinda is), but i want some real industrial training in non documented Android coding.
For last 2 years i have been reading tons of Android articles and documentation on "how to use this library", "how to add this feature", "what this function of this class does", but not much about how to use it efficiently, like the way its used in industry.
When I interned with a startup, all they wanted from me was to push new design changes, fix layout bugs and work as fastly as i could. I had no time to understand their core code, which had so many things that i could have learned : those mvp/mvvm design/architecture patterns, dependency injections, kotlin , coroutines, state management designs, data bindings, eventbuses and handling, and VIPER,RIBS (I mean, not everything was particularly in their code, i picked up a few keywords from here n there)... a lot of stuff that is used by many apps for their codebase.
I can read up these stuff by myself, but i always end up feeling bored coz frankly, i got no big/valuable project to implement it upon and feel excited about it. I feel that open source projects from OSS companies could be my window, but their chat spaces are also mostly empty to discuss/get some guidance.
I want some specific training about these. Can you guys provide any online/offline course/company training/books in this subject, the best practices?1
I needed to align instruction execution to a 64bit boundary, for custom CPU architecture that I'm building. Basically the ISA had 3 types of instruction lengths; 16bit, 32bit, and 48bit. The core did 64bit fetch from the Instruction Cache, the issue was that if an instruction was in between two blocks of data I needed to fetch two blocks. That would impact performance a bit. So I had to modify GCC sources of the ISA that I'm using. So instead of doing it the right way, I just did it the lazy way and modified the GCC backend to print
.p2alignw 3, 0x00ff, 4
.p2alignw 3, 0x00ff, 2
On each 48bit and 32bit instruction to generate NOPs. And it did work lol.
Fucking gdb with your stupid commands, showing me the memory allocation, shos me the data you stupid piece of shit, what is the value pointed by the pointer.
*Segmentation fault**core dumped*
Oh gdb! How much I missed you. Please don't ever leave me okay?
My most recent workaround occurred last week.
We have a demo very soon and I had to change our iOS app to use a new Web API endpoint for uploading content.
Long story short: The existing code is so awful and rigid and dependant on Core Data that I ended up having to completely bypass the service layer of the app and implement the new endpoint as a raw HTTP request. Its gonna take a long time to refactor the existing service layer. All because the new endpoint has a different content type.
How do you think about unit testing/TDD when writing apps? (I'm working this at 3am so might be a bit messy... Just a thought I woke up to).
Whenever I write an app, I don't write unit tests but as I'm developing I may create test functions for specific parts that I run to validate a specific component is working before moving onto the next.
So first, when I get a problem, break it up into components based on the requirements. It's usually sort of input, processor, output sequence.
Where the processor is essentially the core app. And so I start coding it, referring to the input thru an interface, model objects, adding fields as I go along (assume no matter what the input, I will get these before the logic is called). I may add some more interfaces as well for other data I may need but I know won't be going in the first input.
So I write all the logic, functions needed to get a basic app to run that does what I am writing the app for.
Only then do I write a test functions passing in different parameters to make sure the logic and response is what I want and making fixes as necessary. At that point I basically have the simplest version of the app.
(I guess this is sort of like mocking?)
Then build outwards implementing and testing components as I go along and may do some simple refactoring/redesign. (I guess all these tests are functional then, have to start the whole app).
And finally when I have the basic requirements fully complete I will add the "nice to haves" on top via refactoring of specific logic in specific components. Again testing by running the app maybe with simple inputs.
I guess now I'm thinking how do you write unit tests/TDD if the app keeps changing (via adhoc refactorings) as you are creating it?
Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD.
So they're working on a way to store data in DNA. That means next generation computer science students have biology as a core course!
Wanted to know what you guys think about "Dev" jobs that also include making slide shows and presentations?
Eg. Imagine working on an analysis engine. And just when the core functionality is working, your boss wants your team to make presentation for every client that it's going to be used for - using the raw data given by the engine.
Instead of maybe adding that function to the engine itself.
Suddenly your work is now 12+hours of MS office instead of 8 hours of coding.
And a year later. You have 10 unfinished skeleton code architectures, poorly documented and 90% of the test cases never written.
And most of the devs who were on the initial project have either left out of frustration or have been fired because apparently fresher's who can not code with a senior coder level proficiency is not performing well.10
Any recommendations for a slightly older model laptop that is 4+ core, AMD CPU, 8+Gb RAM capable, and comes with a SIM slot for mobile data use.
Running Windows 10 of course. :-)
And at least one USB port so I can plug a mouse in. :-)
And ideally a second monitor..11

My main project in work is making program in C# (right now .NET Standard) that can read scans of invoices that are sent from contractors. I'm working on it for almost two years now (with breaks and only halftime because university). Alone. And for last two months I've been redesigning, refactoring and making whole app "better", using experience and knowledge gained in the last two years.
Obviously my boss wasn't happy with that but I got him to accept it, promising that it'll make it work faster, expansion will be simpler and I'll make core as a separate library that can be used anywhere, not only in the JobRouter ecosystem.
And so I reworked most of the code, made it cleaner, I hope, and a tad quicker. And I was happy with it while testing on a package of invoices. Today I made first integration with customer's JobRouter.
The results aren't any better - in some cases they are much worse. Especially while searching for invoice entries, which can be in any shape or form and on any of document's pages.
I guess, being a Junior, I wasn't really up to the task. I'm sick of working on a "guessing" program that has to work with every invoice template users can imagine. I'm sick of not getting any recognition for what I did good. And I'm sick of constantly being pushed to make it work better when I just don't have any more ideas or my skills are just lacking.
To be honest, I don't know what to do. I'll probably have to work on making it search the data better. But it's not trivial to just look at the code and see errors. Iterating on the code while working with different invoices worked for a bit in older versions, but I reached the point where changes made to make one invoice be read better, made another one worse.
Its like on those GIFs where you squish one bug to make another two appear.
So yeah, I'm currently really doubting my career, skills and intelligence.8
I'm starting to look at how to get devices to send data to an endpoint for storage and analysis. I'm looking at AWS iot stuff like core and green grass but then I'm thinking that a REST API could also do the job. I don't need to connect devices to each other (in first iteration). Dont think I need any edge stuff either. Anybody have any experience with this?3
So the project I have been working on for the past 5 months was finally released yesterday with only very minor problems, this stemmed from both programming side, and users entering data incorrectly.
It has been a rather hectic 5 months. I've had to deal with crap like:
- clients not knowing their own products
- a project manager that didn't document anything (or at least everything into a Google Slides document)
- me writing both requirements AND specifications (I'm a dev, not a PM)
- developers not following said specifications (then having to rewrite all their work)
But the worst thing I think would be the lack of vision from everyone. Everyone sees it as a "project" that should be get it over and done with rather a product that has great potential.
So with the project winding down, and only very few things left to fix/implement. Over these 5 months I learned a lot about domain driven design, Laravel's core, AWS, and just how terrible people are at their jobs. I imagine if I worked with people who gave a damn, or who actually had skills, I probably wouldn't have had such a difficult project.
Right now I'm less stressed but now feel rather exhausted from it all. What kind of things do you to help with the exhaustion and/or slow down of pace?1
I know this is too late to ask this question, but am a final year computer science student, average in all core subjects with 0 knowledge of web development (except a few html tags, but not enough to make a wikipedia like website) or other professional streams.
I know java and python enough to make oop classes and understand code written in them.
A)study more about web dev/ml-ai/testing/other "professional" stuff
B) learn more and strengthen my core subjects , like operating system, algorithms, data structures, etc or
C) learn another core language like C/c++/assembly?27
Was trying to figure out the seemingly unending line of scripts that call scripts scripts and I commented out the core functionality of a job in production. Stayed their for weeks. The script in question? Validates that correct data is loading from an etl job.
Hi Guys if you can share your opinion/experience in what I wrote below it would help me a lot, thanks !
Im a full-stack developer with 4 years of experience, worked with different technologies in backend, frontend, mobile etc.. so I have general knowdgele of how systems works and how they should be built.
So I work as CTO in a startup, Im for almost 2 years here I started here with minimum salary (I decided that, because they said to me we are startup and such things so I wanted to help) 2.2k Euros and it has been almost 2 years without pay rise, so last month I asked for pay rise, but they said to me that they dont have money and sent me +300 euros as gift.
One week ago I wrote to them again (co-founders) that I have a lot of pressure and I dont know if I can handle all of that for much time he told me that I got +300 euro pay rise (which it was gift from them in first place, I refused them to sent this to me), but TODAY CEO and Co-Founder wrote to again me asking if I accept +300 euro pay rise because they can afford to pay me 2.5k or if I dont accept this they can sent me 2.2k again (they think that 2.5k is maximum that they can pay me right now and that this is enough for me).
I want to ask you guys what would you do, would you accepting something like this, considering that right now Im only dev here (yes Im only dev) and Im taking care of these(yes all of these) :
1. Company Website (react js)
2. Web Admin Panel (that clients use to manage their data)(react js)
3. Web Application (that visitors use to see client data)(react js)
4. Widgets (some code that is integrated into clients websites it's same as application, but integrated directly to client website)(react js)
5. Backend of all 3 apps mentioned above (asp.net core)
6. AWS Architecture( some of services : Cognito,Lambda,RDS,API Gateway,CloudFront,S3)
7. DevOps Role
Also consider that I didnt take holidays for 1 year now working on weekends too :)3
spent a few days trying to track down the cause of a thermal shutdown in my workstation. intel 4790k with no overclock would spike to 95C on one core (core1) whenever maxing out all 8 threads, be it real work, mprime, anything with 100% cpu being used. I quadrupled my RAM from 8gb to 32, because its cheap and id like to have all data in memory sometimes, not because I thought that was the problem. I reseated my watercooling block. I checked out the PSU. I unplugged all unnecessary peripherals, drives, etc. It turned out to be a bug in Gigabyte MOBO BIOS (causing temps to be read incorrectly i think, still not exactly sure...) updated from version 5 to 10 and poof now temps are back in the high 50's at full load. it only took 2 days to figure out and i think i learned something
