In a user-interface design meeting over a regulatory compliance implementation:
User: “We’ll need to input a city.”
Dev: “Should we validate that city against the state, zip code, and country?”
User: “You are going to make me enter all that data? Ugh…then make it a drop-down. I select the city and the state, zip code auto-fill. I don’t want to make a mistake typing any of that data in.”
Me: “I don’t think a drop-down of every city in the US is feasible.”
Manage: “Why? There cannot be that many. Drop-down is fine. What about the button? We have a few icons to choose from…”
Me: “Uh..yea…there are thousands of cities in the US. Way too much data to for anyone to realistically scroll through”
Dev: “They won’t have to scroll, I’ll filter the list when they start typing.”
Me: “That’s not really the issue and if they are typing the city anyway, just let them type it in.”
User: “What if I mistype Ch1cago? We could inadvertently be out of compliance. The system should never open the company up for federal lawsuits”
Me: “If we’re hiring individuals responsible for legal compliance who can’t spell Chicago, we should be sued by the federal government. We should validate the data the best we can, but it is ultimately your department’s responsibility for data accuracy.”
Manager: “Now now…it’s all our responsibility. What is wrong with a few thousand item drop-down?”
Me: “Um, memory, network bandwidth, database storage, who maintains this list of cities? A lot of time and resources could be saved by simply paying attention.”
Manager: “Memory? Well, memory is cheap. If the workstation needs more memory, we’ll add more”
Dev: “Creating a drop-down is easy and selecting thousands of rows from the database should be fast enough. If the selection is slow, I’ll put it in a thread.”
DBA: “Table won’t be that big and won’t take up much disk space. We’ll need to setup stored procedures, and data import jobs from somewhere to maintain the data. New cities, name changes, ect. ”
Manager: “And if the network starts becoming too slow, we’ll have the Networking dept. open up the valves.”
Me: “Am I the only one seeing all the moving parts we’re introducing just to keep someone from misspelling ‘Chicago’? I’ll admit I’m wrong or maybe I’m not looking at the problem correctly. The point of redesigning the compliance system is to make it simpler, not more complex.”
Manager: “I’m missing the point to why we’re still talking about this. Decision has been made. Drop-down of all cities in the US. Moving on to the button’s icon ..”
Me: “Where is the list of cities going to come from?”
<few seconds of silence>
Dev: “Post office I guess.”
Me: “You guess?…OK…Who is going to manage this list of cities? The manager responsible for regulations?”
User: “Thousands of cities? Oh no …no one is our area has time for that. The system should do it”
Me: “OK, the system. That falls on the DBA. Are you going to be responsible for keeping the data accurate? What is going to audit the cities to make sure the names are properly named and associated with the correct state?”
DBA: “Uh..I don’t know…um…I can set up a job to run every night”
Me: “A job to do what? Validate the data against what?”
Manager: “Do you have a point? No one said it would be easy and all of those details can be answered later.”
Me: “Almost done, and this should be easy. How many cities do we currently have to maintain compliance?”
User: “Maybe 4 or 5. Not many. Regulations are mostly on a state level.”
Me: “When was the last time we created a new city compliance?”
User: “Maybe, 8 years ago. It was before I started.”
Me: “So we’re creating all this complexity for data that, realistically, probably won’t ever change?”
User: “Oh crap, you’re right. What the hell was I thinking…Scratch the drop-down idea. I doubt we’re have a new city regulation anytime soon and how hard is it to type in a city?”
Manager: “OK, are we done wasting everyone’s time on this? No drop-down of cities...next …Let’s get back to the button’s icon …”

Fucking 20 hour days. Third one this week.
Been at work since 6am, it is now midnight. Spent the morning fixing bush league code mistakes from "expert" onshore developers, and explaining how-to-wipe-your-ass level concepts to some rude cunt who is absolutely going to take credit for my work after I leave.
Now I'm just waiting on this slow boat scp to finish because the invalids the customer hired to manage their infra can't figure out the 3 minute exercise that is standing up a registry, so the container deployment process is fucking export multiple 500mb Redhat images as a tar and ship it across the cripplenet they call a datacenter. And of course the same badmins don't understand rsync and can't manage to get network throughput in a datacenter with a $300M annual budget over 128kbps. I guess that's fast for whatever jugaad horseshit network they're used to.
I've said it before, but it bears repeating. Fuck IBM. They're a cancer and at this point I question the moral compass of anyone who works for them.7 -
(Interview for sde-3 position)
(continuation of https://devrant.com/rants/2132431/... )
Interviewer - *opens laptop. Gives a question.* solve this.
Me - *a bit surprised that such questions were being asked on a sde-3 level*
this is the 4th or 5th question from geeksforgeeks, isn't it? I know the answer to this. Do u still want me to solve it?
Interviewer - *not believing me* Yes
Me - okay. Well this *writing down the original solution mentioned on the site* is the verbatim code mentioned on the website, with complexity O(n^2).
However I feel this is not the optimal solution. Let me write a better solution.
*I provide a better solution*
This has a complexity of O(n log n) . What do you think?
Interviewer - Nope. This could be a lot better.
Me - okay. Let me see. Did some minor changes, added some caching (obviously this will have no effect on the base algorithm) etc
How about now?
Interviewer - nope. Still not good.
Me - okay. Can you tell me how to improve it?
Interviewer - no we are not allowed to solve problems for you. It is not our interview, it is yours.
Me - that makes no sense. Interviews are a two way street. I'd very much like to know the optimal answer to this.
Interviewer - okay
*copies down the answer from geeksforgeeks*
This is good
Me - *at first I thought this was a prank or something. *
I just mentioned this answer here.
Then I spent the next 10 minutes providing a BETTER solution.
May I know how yours is better?
Interviewer - this solution has 2-3 loops. Yours has a function calling itself.
Me - that's called divide and conquer using recursion mf!
Anyways let's take an example and do a dry run.
Interviewer - okay
*we do dry run*
Interviewer - oh yes. Yours ran faster. But it will run fast only sometimes.
Me - yes. Each time the algorithm rolls a dice to decide if it should run fast or slow. You have one goddamn awesome weed dealer man.
I got to go. Thank you for meeting me.14 -
About two years ago I get roped into a something when someone was requesting an $8000 laptop to run an "program" that they wrote in Excel to pull data from our mainframe.
In reality they are using our normal application that interacts with the mainframe and screen scrapping it to populate several Excel spreadsheets.
So this guy kept saying that he needed the expensive laptop because he needed the extra RAM and processing power for his application. At the time we only supported 32 bit Windows 7 so even though I told him ten times that the OS wouldn't recognize more than 3.5 GB of RAM he kept saying that increasing the RAM would fix his problem. I also explained that even if we installed the 64 bit OS we didn't have approval for the 64 bit applications.
So we looked at the code and we found that rather than reusing the same workbook he was opening a new instance of a workbook during each iteration of his loop and then not closing or disposing of them. So he was running out of memory due to never disposing of anything.
Even better than all of that, he wanted a faster processor to speed up the processing, but he had about 5 seconds of thread sleeps in each loop so that the place he was screen scrapping from would have time to load. So it wouldn't matter how fast the processor was, in the end there were sleeps and waits in there hard coded to slow down the app. And the guy didn't understand that a faster processor wouldn't have made a difference.
The worst thing is a "dev" that thinks they know what they are doing but they don't have a clue.7 -
I don't want to write clean code anymore :(
I read Clean Code, Clean Coder, and watched many uncle bob's videos, and I was able to apply best practices and design patterns
I created many systems that really stood the test of time...
Management was kind enough to introduce me to uncle bob clean code in the first place, letting us watch it during work hours. after like one year, my code improved 400% minimum because I am new and I needed guidance from veterans...
That said, to management I am very slow, compared to this other guy, they ask me for a feature and my answer would be like "sure, we need to update the system because it just doesn't support that right now, it is easy though it would take 2 days tops"
they ask the same thing for the other guy : "ok let me see what I can do", 1 hour later, on slack, he writes : done. he slaps bunch of if-statement and make special case that will serve the thing they asked for.
oh 'cool' they say -> but it doesn't do this -> it needs to do that -> ok there is a new bug,-> it doesn't work in build mode-> it doesn't work if you are logged in as a guest, now its perfect ! -> it doesn't work on Android -> ok it works on android but now its not perfect anymore.
and they feel like he is fast (and to be fair he is), this feature? done. ok new bugs? solved. Android compatibility ? just one day ... it looks like he is doing doing doing.
it ends up taking double the time I asked for, and that is not to mention the other system affected during this entire process, extra clean up that I have to do, even my systems that stood the test of time are now ruined and cannot be extracted to other projects. because he just slaps whatever bools and if statements he needs inside any system, uses nothing but Singleton pattern on everything. our app will never be ready-for-business, this I can swear. its very buggy. and to fix it, it needs a change in mentality, not in code.
---------------
uncle bob said : write your code the right way, and the management will see that your code generates less errors, with time, you will earn respect even though they will feel you are slow at first.
well sorry uncle, I've been doing it for a year, my image got bad, you are absolutely right, only when there is no one else allowed to drop a giant shit inside your clean code.
note: we don't really have a technical lead.
-------------------
its been only two days since my new "hack n' slash" meta, the management is already kind of "impressed" ... so I'll keep hacking and slashing until I find a better job.9 -
In my current work, I have two systems to work on (let's name em Systems A and B). Both basically do the same thing; both allow users to book facilities available to them.
System A is already in production. My job is to fix any bugs that come up on said system. System B is an improved version that they wanted me to develop. This would follow a different framework etc. I am already halfway through this system.
Now, here's the fucked up part. The code for system A is a massive clusterfuck. It has unused commented code dated back to ancient times where men had the brain of an ape.
And don't get me started on the fucking logic. One part of the code was to retrieve and display the timeslots available for a chosen facility. The code to do that alone takes up 500++ fucking lines, filled with ajax commands, html manipulation and commented, unused codes..AND THAT'S JUST THE FRONTEND!
The fucking backend was not a problem of smelly code anymore. Nope. It was like a programmer had code diarrhea and shat his backend code all over the project. If I had a pin board, I would have made a crazy wall just to understand what some fucknut was trying to achieve.
Anyway, my supervisor told me to fix some bugs on System A. Knowing how the code was, I told her that I could refactor the code. Since I've already achieved that function on System B, with a shorter and cleaner code, I could just copy that and use on System A. But nope. She SPECIFICALLY told me to just "do whatever to fix the bugs. I don't want to waste time on System A." Okay. Makes sense to me. Whatever. I didn't wanna fuck my head up looking through that mess of a cesspool. So, I came up with a few hacks, not thinking of clean code and fixed whatever bugs there was. I then just pushed to the repo (after testing of course).
This bloody morning, supervisor came in and gave me more bugs to fix. When I thought she was done, she said "Hey. I saw the fix you made to the system. The bugs are fixed but the retrieval of the timeslots is now pretty slow. Could you see what is the problem?"
Slow.. She said that it was slow. And asked if I could fix it. I already told her what the problem was and she did not want me to waste time on it. But she wants me to fix it. WHAT THE FUCK IS WRONG IN HER BLOODY HEAD! I SWEAR TO GOD... UGHHHHH I swear I was already waterboarding her in my head. YOU WANT FAST?? How bout fucking allowing me to refactor the code?? Fucking shit head. I think I should take up yoga.1 -
So, I had a friend who hated VS Code like a fuckton alot however, most of my friends are VS Code users and he's the only one who uses atom. He say that it's greater than VS Code and code then would die sooner.
Fast forward to today, he now ranted at my Discord DM about atom ahving slow startups, extensions that doesn't work, that kind of shit, not to mention hentried to commit improperly indented code (we have nazi style enforcement in out projects regarding codestyle) and made CodeClimate ranted over it.
"That's what you get for shitting VS Code" I said. Hours later, he tried VS Code and he instantly fell in love with it.
One down, more to go12 -
Today was the most fuckedup day of my internship as a software developer. I have this shithead manager who doesnt know how to explain the client requirements properly and keeps on fucking yelling at me for not understanding the requirement and not coming up with the right output. That asshole compares me with the other teammate as to how fast he is and how slow i am to even write 5 lines of code in python.(I am new to python). He has yelled at me in his cabin with the door open so that everyone on the floor could hear. Most humiliating and disappointing day of my life. I dont feel like seeing that shitheads face again. I just have a month left and i will be happy if the opportunity doesnt get converted to a full time. Todays events have made me doubt myself to a great extent and has left me disheartened. Ranting abt it makes me feel a little better.7

Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).46 -
I forgot what it was like to have a productive day!
I’m rewriting the Apple wallet pass code to make it fully customizable instead of mostly static, and it’s beautiful.
The code was horrible tangled spaghetti before (and soo slow) but now it’s clean and fast and modular and absolute bliss to spec. Yay, dependency injection!
I actually had fun working today! 😊
It’s been the first time in months.8 -
Biggest challenge I overcame as dev? One of many.
Avoiding a life sentence when the 'powers that be' targeted one of my libraries for the root cause of system performance issues and I didn't correct that accusation with a flame thrower.
What the accusation? What I named the library. Yep. The *name* was causing every single problem in the system.
Panorama (very, very expensive APM system at the time) identified my library in it's analysis, the calls to/from SQLServer was the bottleneck
We had one of Panorama's engineers on-site and he asked what (not the actual name) MyLibrary was and (I'll preface I did not know or involved in any of the so-called 'research') a crack team of developers+managers researched the system thoroughly and found MyLibrary was used in just about every project. I wrote the .Net 1.1 MyLibrary as a mini-ORM to simplify the execution of database code (stored procs, etc) and gracefully handle+log database exceptions (auto-logged details such as the target db, stored procedure name, parameter values, etc, everything you'd need to troubleshoot database errors). This was before Dapper and the other fancy tools used by kids these days.
By the time the news got to me, there was a team cobbled together who's only focus was to remove any/every trace of MyLibrary from the code base. Using Waterfall, they calculated it would take at least a year to remove+replace MyLibrary with the equivalent ADO.Net plumbing.
In a department wide meeting:
DeptMgr: "This day forward, no one is to use MyLibrary to access the database! It's slow, unprofessionally named, and the root cause of all the database issues."
Me: "What about MyLibrary is slow? It's excecuting standard the ADO.Net code. Only extra bit of code is the exception handling to capture the details when the exception is logged."
DeptMgr: "We've spent the last 6 weeks with the Panorama engineer and he's identified MyLibrary as the cause. Company has spent over $100,000 on this software and we have to make fact based decisions. Look at this slide ... "
<DeptMgr shows a histogram of the stacktrace, showing MyLibrary as the slowest>
Me: "You do realize that the execution time is the database call itself, not the code. In that example, the invoice call, it's the stored procedure that taking 5 seconds, not MyLibrary."
<at this point, DeptMgr is getting red-face mad>
AreaMgr: "Yes...yes...but if we stopped using MyLibrary, removing the unnecessary layers, will make the code run faster."
<typical headknodd-ers knod their heads in agreement>
Dev01: "The loading of MyLibrary takes CPU cycles away from code that supports our customers. Every CPU cycle counts."
<headknod-ding continues>
Me: "I'm really confused. Maybe I'm looking at the data wrong. On the slide where you highlighted all the bottlenecks, the histogram shows the latency is the database, I mean...it's right there, in red. Am I looking at it wrong?"
<this was meeting with 20+ other devs, mgrs, a VP, the Panorama engineer>
DeptMgr: "Yes you are! I know MyLibrary is your baby. You need to check your ego at the door and face the facts. Your MyLibrary is a failed experiment and needs to be exterminated from this system!"
Fast forward 9 months, maybe 50% of the projects updated, come across the documentation left from the Panorama. Even after the removal of MyLibrary, there was zero increases in performance. The engineer recommended DBAs start optimizing their indexes and other N+1 problems discovered. I decide to ask the developer who lead the re-write.
Me: "I see that removing MyLibrary did nothing to improve performance."
Dev: "Yes, DeptMgr was pissed. He was ready to throw the Panorama engineer out a window when he said the problems were in the database all along. Didn't you say that?"
Me: "Um, so is this re-write project dead?"
Dev: "No. Removing MyLibrary introduced all kinds of bugs. All the boilerplate ADO.Net code caused a lot of unhandled exceptions, then we had to go back and write exception handling code."
Me: "What a failure. What dipshit would think writing more code leads to less bugs?"
Dev: "I know, I know. We're so far behind schedule. We had to come up with something. I ended up writing a library to make replacing MyLibrary easier. I called it KnightRider. Like the TV show. Everyone is excited to speed up their code with KnightRider. Same method names, same exception handling. All we have to do is replace MyLibrary with KnightRider and we're done."
Me: "Won't the bottlenecks then point to KnightRider?"
Dev: "Meh, not my problem. Panorama meets primarily with the DBAs and the networking team now. I doubt we ever use Panorama to look at our C# code."
Needless to say, I was (still) pissed that they had used MyLibrary as dirty word and a scapegoat for months when they *knew* where the problems were. Pissed enough for a flamethrower? Maybe.6 -
Really fed up with my colleague and possibly my job. Am starting to doubt am cut out to be a developer
Am a junior java dev , been working working for this company for about 2 years now. Although they hired me to be a java dev, they pretty much exclusively had me working on JavaScript crap because none of the other more senior devs wanted to do even so much as poke JS with a long stick....
Oh and the salary was crap but i figured since i had barely 3 years of exp i thought i would stick with it for a while
But a few months ago after seeing other opportunities I got fed up and threatened to quit , already started interviewing etc
Got an offer, not exactly what i wanted but better than where i was. Went to quit but they freaked out and started throwing money at me. They matched and exceed the other salary and promised to addressed the issues that made me want to leave. Ie get me to work more on the java side of the project and have me work with someone more senior who could sort of mentor me, i had been working semi solo on the js shit till then...
The problem is that my supposed mentor is selfish prick... he is the sort of guy who comes in real early, basically he goes to early morning prayer then come in at some ungodly hour and fuckoff home around 3pm
He does all his work early morning then spends the rest of the day with his headphones on stealthily watching youtube, amazon, watching cricket, reading about Palestine , how oppressed muslims are or building a website for some mosque.
I asked him to let me sit with him so that I could just learn how this or that part of the sys worked , he agreed then the very next day comes in and does all the work before i get in at 9 , i asked him how he did it and he tells me oh just read the code.
Its not as simple as that, out codebase is an old pile of non standard legacy dog shit. Nothing works as it should, i tried to go through documentation online for the various stuff we use , but invariably get stuck when i try the usual approach because it turns out the original devs had essentially done a lot of custom hacks and cowboy coding to get stuff working, they screwed around with some of the framework jars & edited libraries to get stuff to work, resulting in some really weird OSGI errors.
My point is that i cant really just "read the code" or google ...
I gotta know a bit more what was actually modified and a lot of this knowledge isn't fucking documented, theres a lot of " ohhh that weird bug yeah yeah that happens cuz x did this hack some years ago to fix this issue and we kinda built on it, yeah we weren't supposed to do that but heyyy what u gonna do, just do this or that instead"
I was asked to set up a web service to export something, since thats his area of expertise and he is suppose to be teaching me the ropes, i asked him to explain where i should start and what would the general workflow be, his response is to tell me to just copy the IMPORT service and rename it to export then "just do it um change it or something" very helpful indeed (building enterprise application here nothing complex at all!!)
He sits right next to me so i can see how much works he actually does, i know when he just idly sitting there so thats when i ask him questions, he always has his earphones on so each time i gotta find a way to get his attention with a poke or a wave, he will give a heavy sigh and a weary look as he removes his headphones, listen to my question then give me the shortest answer possible before IMMEDIATELY turning away and putting his headphones on as fast as possible regardless of whether I actually understood or even heard what he said. If i ask another question ( am talking like an immediate follow up question for a clarification or something) he will
Do the whole sigh + tired look routing to make me know yeah you are disturbing me. ( god was so happy the day he accidentally sat on and broke them)
Yesterday i caught a glance at his screen as i was sitting down and i think he and another dev were talking about me
That am slow with my work and take forever to get into gear.
Starting to have doubts about my own ability n wether am really cut out to be a developer. I know i can work hard but its impossible to do so when you have no clue where to start and unable to look it up since all the custom hacks doesn't really allow any frame of reference.
Feels like am being handicapped and mocked, yesterday i just picked up my gear n left the office.
I never talk ill about my colleagues, whenever i have a 121 with my mgr i always all is fine, x n y are really helpful etc
I tried to indirectly tell my other colleague about this guy, he told me that guy had kinda mentally checked out of this job and was just going through on auto pilot and just laughed it off (they have been working together for almost a decade and a buddies) my other colleague is pretty nice but he usually swamped with work so i feel bad to trouble him.
Am really Fed up with it all7 -
I don't know if I'm being pranked or not, but I work with my boss and he has the strangest way of doing things.
- Only use PHP
- Keep error_reporting off (for development), Site cannot function if they are on.
- 20,000 lines of functions in a single file, 50% of which was unused, mostly repeated code that could have been reduced massively.
- Zero Code Comments
- Inconsistent variable names, function names, file names -- I was literally project searching for months to find things.
- There is nothing close to a normalized SQL Database, column ID names can't even stay consistent.
- Every query is done with a mysqli wrapper to use legacy mysql functions.
- Most used function is to escape stirngs
- Type-hinting is too strict for the code.
- Most files packed with Inline CSS, JavaScript and PHP - we don't want to use an external file otherwise we'd have to open two of them.
- Do not use a package manger composer because he doesn't have it installed.. Though I told him it's easy on any platform and I'll explain it.
- He downloads a few composer packages he likes and drag/drop them into random folder.
- Uses $_GET to set values and pass them around like a message contianer.
- One file is 6000 lines which is a giant if statement with somewhere close to 7 levels deep of recursion.
- Never removes his old code that bloats things.
- Has functions from a decade ago he would like to save to use some day. Just regular, plain old, PHP functions.
- Always wants to build things from scratch, and re-using a lot of his code that is honestly a weird way of doing almost everything.
- Using CodeIntel, Mess Detectors, Error Detectors is not good or useful.
- Would not deploy to production through any tool I setup, though I was told to. Instead he wrote bash scripts that still make me nervous.
- Often tells me to make something modern/great (reinventing a wheel) and then ends up saying, "I think I'd do it this way... Referes to his code 5 years ago".
- Using isset() breaks things.
- Tens of thousands of undefined variables exist because arrays are creates like $this[][][] = 5;
- Understanding the naming of functions required me to write several documents.
- I had to use #region tags to find places in the code quicker since a router was about 2000 lines of if else statements.
- I used Todo Bookmark extensions in VSCode to mark and flag everything that's a bug.
- Gets upset if I add anything to .gitignore; I tried to tell him it ignores files we don't want, he is though it deleted them for a while.
- He would rather explain every line of code in a mammoth project that follows no human known patterns, includes files that overwrite global scope variables and wants has me do the documentation.
- Open to ideas but when I bring them up such as - This is what most standards suggest, here's a literal example of exactly what you want but easier - He will passively decide against it and end up working on tedious things not very necessary for project release dates.
- On another project I try to write code but he wants to go over every single nook and cranny and stay on the phone the entire day as I watch his screen and Im trying to code.
I would like us all to do well but I do not consider him a programmer but a script-whippersnapper. I find myself trying to to debate the most basic of things (you shouldnt 777 every file), and I need all kinds of evidence before he will do something about it. We need "security" and all kinds of buzz words but I'm scared to death of this code. After several months its a nice place to work but I am convinced I'm being pranked or my boss has very little idea what he's doing. I've worked in a lot of disasters but nothing like this.
We are building an API, I could use something open source to help with anything from validations, routing, ACL but he ends up reinventing the wheel. I have never worked so slow, hindered and baffled at how I am supposed to build anything - nothing is stable, tested, and rarely logical. I suggested many things but he would rather have small talk and reason his way into using things he made.
I could fhave this project 50% done i a Node API i two weeks, pretty fast in a PHP or Python one, but we for reasons I have no idea would rather go slow and literally "build a framework". Two knuckleheads are going to build a PHP REST framework and compete with tested, tried and true open source tools by tens of millions?
I just wanted to rant because this drives me crazy. I have so much stress my neck and shoulder seems like a nerve is pinched. I don't understand what any of this means. I've never met someone who was wrong about so many things but believed they were right. I just don't know what to say so often on call I just say, 'uhh..'. It's like nothing anyone or any authority says matters, I don't know why he asks anything he's going to do things one way, a hard way, only that he can decipher. He's an owner, he's not worried about job security.13 -
I need some advice here... This will be a long one, please bear with me.
First, some background:
I'm a senior level developer working in a company that primarily doesn't produce software like most fast paced companies. Lots of legacy code, old processes, etc. It's very slow and bureaucratic to say the least, and much of the management and lead engineering talent subscribes to the very old school way of managing projects (commit up front, fixed budget, deliver or else...), but they let us use agile to run our team, so long as we meet our commitments (!!). We are also largely populated by people who aren't really software engineers but who do software work, so being one myself I'm actually a fish out of water... Our lead engineer is one of these people who doesn't understand software engineering and is very types when it comes to managing a project.
That being said, we have this project we've been working for a while and we've been churning on it for the better part of two years - with multiple changes in mediocre contribution to development along the way (mainly due to development talent being hard to secure from other projects). The application hasn't really been given the chance to have its core architecture developed to be really robust and elegant, in favor of "just making things work" in order to satisfy fake deliverables to give the customer.
This has led us to have to settle for a rickety architecture and sloppy technical debt that we can't take the time to properly fix because it doesn't (in the mind of the lead engineer - who isn't a software engineer mind you) deliver visible value. He's constantly changing his mind on what he wants to see working and functional, he zones out during sprint planning, tries to work stories not on the sprint backlog on the side, and doesn't let our product owner do her job. He's holding us to commitments we made in January and he's not listening when the team says we don't think we can deliver on what's left by the end of the year. He thinks it's reasonable to expect us to deliver and he's brushing us off.
We have a functional product now, but it's not very useful yet and still has some usability issues. It's still missing features, which we're being put under pressure to get implemented (even half-assed) by the end of the year.
TL;DR
Should I stand up for what I know is the right way to write software and push for something more stable sometime next year or settle for a "patch job" that we *might* deliver that will most definitely be buggy and be harder to maintain going forward? I feel like I'm fighting an uphill battle in trying to write good quality code in lieu of faster results and I just can't get behind settling for crap just because.9 -
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 -
After a lot of work I figured out how to build the graph component of my LLM. Figured out the basic architecture, how to connect it in, and how to train it. The design and how-to is 100%.
Ironically generating the embeddings is slower than I expect the training itself to take.
A few extensions of the design will also allow bootstrapped and transfer learning, and as a reach, unsupervised learning but I still need to work out the fine details on that.
Right now because of the design of the embeddings (different from standard transformers in a key aspect), they're slow. Like 10 tokens per minute on an i5 (python, no multithreading, no optimization at all, no training on gpu). I've came up with a modification that takes the token embeddings and turns them into hash keys, which should be significantly faster for a variety of reasons. Essentially I generate a tree of all weights, where the parent nodes are the mean of their immediate child nodes, split the tree on lesser-than-greater-than values, and then convert the node values to keys in a hashmap to make lookup very fast.
Weight comparison can be done either directly through tree traversal, or using normalized hamming distance between parent/child weight keys and the lookup weight.
That last bit is designed already and just needs implemented but it is completely doable.
The design itself is 100% attention free incidentally.
I'm outlining the step by step, only the essentials to train a word boundary detector, noun detector, verb detector, as I already considered prior. But now I'm actually able to implement it.
The hard part was figuring out the *graph* part of the model, not the NN part (if you could even call it an NN, which it doesn't fit the definition of, but I don't know what else to call it). Determining what the design would look like, the necessary graph token types, what function they should have, *how* they use the context, how thats calculated, how loss is to be calculated, and how to train it.
I'm happy to report all that is now settled.
I'm hoping to get more work done on it on my day off, but thats seven days away, 9-10 hour shifts, working fucking BurgerKing and all I want to do is program.
And all because no one takes me seriously due to not having a degree.
Fucking aye. What is life.
If I had a laptop and insurance and taxes weren't a thing, I'd go live in my car and code in a fucking mcdonalds or a park all day and not have to give a shit about any of these other externalities like earning minimum wage to pay 25% of it in rent a month and 20% in taxes and other government bullshit.4 -
The more I'm on here the more I remember all the shit I have had to deal with in the past.
Anyway, lets rant! I just moved cities after college to be closer to my family, I didnt have any work lined up at that stage but started job hunting the moment I was settled in, I did some freelance for smaller companies to stay afloat.
Eventually I got a job at this agency startup where "SEO" was there main focus, still very inexperienced they put me on frontend and data capturing but will teach me how to code using their systems in due time. At this stage I was getting paid minimum wage, but I was doing minimum work and it wasnt that bad.
A new investor bought 49% of the company and immediately moved into the office space to focus more on marketing (He was one of those scaly marketing guys that will sell you babies if he could get his hands on enough to make a profit).
This is where everything starts going to shit. He hires a bunch of "SEO Gurus", fills up the small office with people like sardines squished together. Development was still our main money maker at this stage, so there where 3 new more senior developers at this stage and I started learning a lot really fast.
Here are some of the issues we had to deal with:
1. Incentives - Great more money, haha! No, No, you where 5 minutes late so you only get half of the promised amount.
2. For every minute you are late we will deduct it from you paycheck (Did I mention I was getting paid minimum wage).
3. If you take a smoke break we will dock it from your pay.
4. Free gym membership to the gym downstairs, but you can only go once a week during your lunch.
5. No pay raises if you cant prove your worth on paper.
He on purposely made up shitty rules and regulations to keep us down and make as much profit as he could.
Here are some shitty stuff he has done:
1. We arent getting a 13th check this year because the company didnt make a big profit - while standing next to his brand new BMW.
2. Made changes over FTP on clients work because we where too slow to get to it, than blames me for it because its broken the next day and wants to give me a written warning for not resolving the issue Immediately. They went as far as wanting to fire me for this, gave me 1 day notice for meeting and that I can bring a lawyer to represent me (1 day notice is illegal, you need 5 days where I am from), so I brought a lawyer since my mom was a lawyer. They freaked the fuck out and started harassing me about this a week later.
3. Would have meetings all the time about how much money the company is making, but wont be raising our pay since no one has proven they are worth it yet.
4. Would full on yell at employees infront of the entire office if they accidentally made an mistake on a clients project.
One one occasion I took a week off for holiday, my coworker contacted me to ask a question and I answered that I will handle it when I am back the following week. Withing 2 hours my other boss phones me in a rage, "he is coming to fetch the company laptop from my house in 5 minutes, he will let me know when he arrives. Gives me no time to talk at all and hangs up - I have figured out what has happened by now so when he showed up he has this long speech about abandonment, and trust and loyalty to the company. So I pass him my laptop once he shut up and said: "You do know I am on holiday leave which you approved, right?", he goes even more silent and passes me back my laptop without saying anything, and drives off.
While the above was happening Douche manager back at the office has a rage as well and calls the whole office (25 people) to a meeting talking about how I abandoned the company and how disgraceful that is.
Those are the shitty experiences I can remember, there where many more like this. All of the above eventually led to me going into a deep depression and having panic attacks weekly, from being overworked or scared to step out of line. Its also the reason I almost stopped coding forever at that stage. I worked there for 2.5 years with the abuse.
I left 2 weeks after the last shit show, I am ok now and have my anxiety and depression well under control if not almost gone completely.
Ran into Douche Manager a few months ago after 9 years, the company got bought out and the first person they fired was him. LOL! He now has his own agency and is looking for Developers (They are hard to find he says), little does he know I spread his name far and wide to all and every Dev I knew and didnt know to avoid working for him at all costs. Seems like word of mouth still works in this digital age.
Thanks for reading this far!5 -
So I got this new job as Java developer, the people are really great but is the kind of companies that only takes care for fast results and not for code quality.
Because this I have to deal with libraries updated 4 years ago, classes with 8000 lines, methods with 500 lines, a WHOLE lot of work arounds because there is no time to really fix the issue unless it affects directly the customer (something not working or being really slow) aaand we use fucking svn.
Some of this practice's they know and encourage it (+1000 lines classes for example) and every time I try to talk about good practices in the code everyone seems so interested but there is always no time.
Sooo I will stay here for at least two years, I hope I can make a change for good in their code smells.3 -
This always gets me:
Developers complaining that their 4 year old / cheap ass computer is slow.
Get. A. New. One.
It's not that hard.
Here, let me do one for you:
https://computeruniverse.net/en/...
I just went to a site that delivers across Europe, and selected a cheap laptop with a decent CPU and SSD. Short on RAM, sure, and without a Windows License. But you can buy RAM for an additional 50$, and that brings you to a total of 550€, delivery included. And it will WORK. And it will be fast.
It's too expensive?
No, not exactly. Wherever you are in the world, if you can code decently, good enough to have the right to complain about development tools, you are eligible to at least 10$ per hour income as a freelancer across the globe. I've had such opportunities offered to me by many organizations, especially non-profit ones that need cheap employees. I actually was offered more but let's stick to 10$ per hour.
So that's 1600$ per month. Enough to buy 3 such laptops. Oh, taxes, I forgot. So you get 2 laptops. Wait! You need food and everything else. Well if you're in a country where that offer actually makes sense, then it's likely that you can live off of 400$ per month quite well. Maybe 800$ if you need to pay rent.
So that's roughly 1 month of work for a laptop that will make you not waste time on waiting for stuff.
Sweet! 1 Month! What does it get me?
Well assuming that you have no laptop, it gets you A JOB that pays you 1600$ per month.
But if you DO have a laptop, you can sell it for cheap, and benefit from the following:
1. Boot-up time from 30-60 seconds to 10 seconds.
2. Installing software - from 1 minute to 10 seconds.
3. Opening a browser - from 10 seconds to 1 second.
4. Opening an advanced text editor (Atom, VS.Code) - from 10 seconds to 1 second.
5. Searching for a file on your entire hard drive - from 1 hour to 2 minutes.
....
You get the point. Waiting is reduced by several times.
So how much do you really wait when coding?
Well are you compiling? Are you opening a new project and the IDE needs to re-index the files? Are you opening programs like a terminal emulator, browser and such? Are you using virtual machines for dev environments?
Well all of these processes become several times faster. Depending on how often you do it, you'll be saving yourself from 1 hour per day to upto 4 hours per day (my case, where a HDD would be just out of the question).
How much is that time worth? At least 10$ per day. If you're working for 20 days per month, 240 days per year, that's a total of 2400$. And for the life time of that crappy laptop of 2 years, that's 4800$ saved. And that's with hugely conservative numbers. Nobody pays 10$ per hour any more, except if you've just started in the industry. I know because I've been there.
Please, for all that's sacred to you, justify right here, right now, HOW THE FUCK can you not afford to get that 8GB of RAM, that cheap ass SSD for 100$, or even a brand new laptop (hey! it's even portable and has FHD graphics on it!) for 550$.
That's why every time I hear someone who is a professional developer complain that they don't have money for a decent machine, I have to ask: why the fuck are you wasting yours and everyone else's time?!10 -
Life is good when you're responsible only for your task, code you write.
While i had souch a beautiful life, I could come to wrk, make coffe, magic and be happy. Sometimes it would be fast, sometimes slow. Sometimes I had to learn before implementing, sometimes I just needed to code it down. I had working hours. I had only TL and client to deal with.
If you dislike working with your collegues, imagine being responsible for their work and feel good.1 -
I wrote an algorithm that incorporates a 3rd party API. and the algorithm is so fast and optimized that I started to get 429 status codes from the third party API, asking me to slow down my requests, which I didn't think was an issue when I tested on local env.
Now I'm on purpose slowing down my code, to prevent that from happening.
Talk about suffering from success.8 -
I just realized that I subconsciously believe more lines of code means slower code.
It's not intellectual. I understand that little lines of code often are just calling other code. That this is not how Big O works or does not replace benchmarking and that some data structure requires a lot of code for immense speed up. E.g: B-Trees with sizes at page size for big amounts of data read from a secondary storage location.
But still, when I see a function with just 3 to 5 lines, my inner monkey believes it must be fast.
Know your biases, I guess.3 -
Situation: I have a love hate relationship with python due to the lack of types as I have in more established languages such as C#, Java and shit even TypeScript
Situation (cont): A rather large codebase that i have developed for multiple processes at work run on Python.
I don't hate it, I just don't absolutely love it, there is a lot of things to like about Python, but man I do have some conflicts with it, I have been facing out to use other solutions that feel scripty, such as the newer versions of C# with .net, but I would say that about 80% of our codebase runs on Python, the rest is PHP.
I am somewhat traditional in the way my programs run, I started with C++ and Java, then for whatever reason (I blame codecademy at the time) switched over to Ruby and Javascript, mostly Javascript. I do not remember how I found Python, I do remember learning it with an online tutorial, shit was easy to get started with.
My codebase running on Python is huge, and they do a lot from automation scripts, to data gathering and database management, never had I been bitten with the "oh noes is so slow" bug since my code is not Google level big, for everything else Python seems rather fast imho
I dunno, big time love hate relationship9 -
I freaking hate slow IDEs, especially ones made in Java.
I used to use an IDE/text editor called geany, and it was great, you could do almost every language in it and it worked great. It was fast, and efficient, it was a no-nonsense editor. That was when I was a kid, but I got in univ and got a job, so I had to start using big boy """""enterprise""""" IDEs like eclipse.
Eclipse, netbeans, and intellij (basically every Java based IDE except BlueJ) are exactly what is wrong with IDEs. They are clunky editors that frankly would be better off gone. They are slow, eat RAM like crazy (like most Java software). You just CANNOT have eclipse open for extended periods of time, because it WILL take up too much resources and get slow as heck. Android Studio (based on intellij) is a nightmare to work with. It just does not want to cooperate with you (I will agree they have improved a lot though).
I cannot believe I am saying this, but even the electron based IDEs like atom and code-oss are better than them. They are very easily expandable, something that Java was supposed to be, but is not. They have tons of plugins. Even if its not there, you can make one without having to spend a lifetime making the plugin! They look good. I never thought that going from IDEs with """""enterprise""""" UIs to something modern like code-oss would feel this great. Its ridiculous, I don't want to create a darn project for every single file that I want to edit, I just want syntax highlighting for a single .sh file that I want to edit right now. A project is just a way to logically define what is one "unit" or a "container for multiple files", you know what else is that? A simple directory.
Also I don't want 9 billion .xml files for the IDE to store its crap. Just make a .vscode like folder to hide your shit.11 -
This shit is long story of my computer experience over my lifetime.
When I was young I got my first PC with windows it was not so bad. It required safe shut down of it’s fat32 partition. From time to time I needed to reinstall it cause of slow down but I got used to it I was only a gamer.
Time passes and I got more curious about computers and about this linux. Everything worked there but installation of anything was complete madness and none of windows programs worked well, and I wanted to play games and be productive so I sticked with windows.
I bought hp laptop once with nvidia card, it was overheating and got broken. So I bought toshiba and all I told to the seller was I want ATI card. Took me 5 minutes to do it and I was faster then my friend buying pack of cigarettes because I was earning money using computer.
Then I grown up running my small one person programming businesses and I wanted to run and compile every fucking program on this world. I wanted linux shell commands. I wanted package manager, and I wanted my os to be simple because I wasn’t earning money by using my os but by programming. So after getting my paycheck I bought mac. I can run windows and linux on vm if I need it. I try not to steal someones work so I didn’t want to run hackintosh. I am using this mac for some time.
Also I use playstation for gaming. Because I only want to run and play game I am not excited about graphics but gameplay. I think I am pragmatic person.
I can tell you something about my mac.
When I close lid it go sleep when I open it wakes up instantly. I never need to wonder if I want to hibernate or shut down or sleep and drain battery. It is fucking simple.
When I want to run or open something it doesn’t want me to wait but it gives me my intellij or terminal or another browser or whatever I search for. Yeah search is something that works.
Despite it got 8 gigs of ram I can run whatever number of programs I want at the same speed. The speed is not very fast sometimes but it’s constant fast.
I have a keychain so my passwords are in one place I can slow down shared internet speed, I can put my wifi in monitor mode and I don’t need to install some 3rd party software.
And now I updated my mac to high sierra, cause it’s free and I want to play with ios compilation. Before I did it I didn’t even backup whole work. I just used time machine and regular backups. And guess what, it still works at the same speed and all I did was click to run update and cook something to eat.
When I got bored I close the lid, when got idea open lid and code shit, not waiting for fucking wakeup or fucking updates.
I wanted to rant apple products I use but they work, they got fucking updates all along at the same time. And all of updates are optional.
I cannot tell that about all apple products but about products I use.
I think I just got old and started to praise my limited time on this world. Not being excited about new crap. When I buy something I choose wisely. I bought iPhone. I can buy latest iPhone x but I bought iPhone 7 cause it’s from fucking metal. And I know that metal is harder then glass, why the fucking apple forgot about it? I don’t know.
I know that I am clumsy and drop stuff. Dropped my phone at least 100 times and nothing.
I am not a apple fan boy I won’t buy mac with this glowing shit above keyboard that would got me blind at night.
I buy something when I know that it can save my time on this world. I try to buy things that make me productive and don’t break after a year.
So now piece of advise, stop wasting your time, buy and update wisely, wait a week or a month or a year when more people buy shit and buy what’s not broken. And if something’s broken rant this shit so next customer can be smarter.

I have just slept for a minimum of 5 hours. It is 7:47 PM atm.
Why?
We have had a damn stressful day today.
We have had a programming test, but it really was rather an exam.
Normally, you get 30 minutes for a test and 45 minutes for an exam.
In this "test" we have had to explain what 'extends' does and name a few advantages of why one should use it.
Check.
Read 3 separate texts and write the program code on paper. It was about 1 super class and 1 sub class with a test class in Java.
Check.
Task 3: Create the UML diagram of the code from above. *internally: From above? He probably means my code since there is no other code there. *Checks time*. I have about 3 minutes left. Fuck my life.*
Draws the boxes. Put the class names in each of them. A private attribute for the super class.
Teacher: Last minute!
Draw the arrow starting starting from the sub class to the super class.
Put my name on each written paper. And mentally done for the day. Couldn't finish the last task. Task 3.
During this "test", I heard the frustrations of my classmates. Seemed like everyone was pretty much pissed.
After a short discussion with the teacher who also happens to be the physics professor of a university nearby.
[If you are reading this, I hope that something bad happens to you]
The next course was about computer systems. Remember my recent rant about DNS, dhcp, ftp, web server and samba on ubuntu?
We have had the task to do the screenshots of the consoles where you proof that you have dhcp activated on win7 machine etc. Seemed ok to me. I would have been done in 10 minutes, if I would be doing this relaxed. Now the teacher tells us to change the domain names to <surnameOfEachStudent>.edu.
I was like: That's fine.
Create a new user for the samba server. Read and write directories. Change the config.
Me: That should be easy.
Create new DNS entries in the configs.
Change the IPv6 address area to 192.168.x.100-200/24 only for the dhcp server.
Change the web server's default page. Write your own text into it.
You will have 1 hour and 30 minutes of time for it.
Dumbo -ANGRY-CLIENT-: Aye. Let us first start screenshotting the default page. Oh, it says that we should access it with the domain name. I don't have that much time. Let us be creative and fake it, legally.
Changes the title element so that it looks like it has been accessed via domain name. Deletes the url and writes the domain name without pressing Enter. Screenshot. Done. Ok, let us move to the next target.
Dhcp: Change lease time. Change IP address area. Subnet mask. Router. DNS. Broadcast. Optional domain name. Save.
Switches to win7.
ipconfig /release
ipconfig /renew
Holy shit it does not work!
After changing the configs on ubuntu for a legit 30 minutes: Maybe I should change the ip of the ubuntu virtual machine itself. *me asking my old self: why did not you do that in the first place, ass hole?!*
Same previous commands on win7 console. Does not work. Hmmm...
Where could be the problem?
Check the IP of the ubuntu server once again. Fml. Ubuntu did not save when I clicked on the save button the first time I have changed it. Click on save button 10 times to make sure it really is saved now lol.
Same old procedure on win7.
Alright. Dhcp works. Screenshot.
Checks time. 40 minutes left.
DNS:It is your turn. Checks bind9 configs. sudo nano db.reverse.edu.
sudo nano db.<mysurname>.edu.
Alright. All set. It should work now.
Ping win7 from ubuntu and vice versa. Works. Ping domain name on windows 7 vm. Does not work.
Oh, I forgot to restart the bind9 server on ubuntu.
sudo service bind stop
" " " start
Check DNS server IP on win7. It looks fine.
It still doesn't work. Fuck it. I have only 20 minutes left. Samba. Let us do this!
10 minutes in. No result. I don't remember why. I already forgot why I have done for it. It was a very stressful day.
Let us try DNS again.
Oh shit. I forgot the resolver!
sudo nano /etc/resolv.conf
The previous edits are gone. Dumb me. It says it in the comments. Why did not I care about it. Fuck it.6 minutes left. Open a yt video real quick. Changes the config file. Saves it. Restarts DNS and dhcp. Closes the terminal and opens a new one. The changes do not affect them until you reopen them. That's why.
Change to win7.
Ping works. How about nsloopup.
Does not work.
Teacher: 2 minutes left!
Fuck it.
Saves the word document with the images in it. Export as pdf. Tries to access the directories of the school samba server. Does not work. It was not my fault tho. Our school server is in general very slow. It feels like they are not maintained and left alone like this in the dust from the 90s.
Friend gets the permission to put his document on a USB and give the USB to the teacher.
Sneaky me: Hey xyz, can you give me your USB real quick?
Him: sure.
Gets bombed with "do you want to format the USB?" pop-ups 10 times. Fml. Skips in a fast way.
Transfers the pdf. Plug it out. Give it back.
After this we have had to give a presentation in politics. I am done.6 -
Little addition on my rant about the enter and leave instructions being better than push mov sub for stackframes:
I had that debate with a friend of mine, who tried the same code ... and failed to get enter to be as fast. Infact, for him, enter was twice as slow, on his older computer even 3times as slow.
Mhh... pretty bad. basically blows up my whole point.
I tried the code on my computer... Can't reproduce the error.
Weird.
"Which CPU are you on?"
>"I'm on Intel"
Both of his computers are on intel. I use an amd ryzeni1600. Now this might be a bit of a fast conclusion, but I think that its safe to say that intel should atleast do better for SOME parts of their CPUs.9 -
grrrr
last week my laptop died out of nowhere. it stopped recognizing the one drive in it. I lost a bunch of files, code. evidently ssds fail out of nowhere unlike hdds which slow down and error all the time before ultimate failure
my warranty for this 4k$ laptop expires in 12 months and this was month 13. nice. I don't like warranties anyway, and the site said they would replace things with "comparable hardware, sometimes refurbished" wtf no thanks
so I found some guides of people upgrading the drive in this laptop. seemed easy enough, unlike older laptops from back when I was in school where you had to take out 12 things first to get to anything
unfortunately I needed a specific screwdriver. I walked several miles to the nearby hardware store thinking they would have said screwdriver. the old guy in the basement said there was a kit where it started from t4 (I needed t5), but he had just sold out his last one. I checked their online store with a friend for a while on my way back home and we kept finding torx screws but the wrong sizes. fuck.
he said screwdrivers this small are only used for electronics, asked if there's any other hardware stores and there aren't near me
however it occurred to me this strip mall has a lot of suspicious computer stores on it. so I walked back up the street looking for one.
found one with a suspicious poster, saying it was an internet cafe but the last point on their poster said they do repairs. walked in. nobody is in there, suspiciously 2 desks with old computers all empty, then you go forward in this dark cave, with plastic wrapped implements on the walls, you finally find a glass shield and behind it was a meek Asian man that took me a moment to notice
I asked him if he had t5
he handed me a plastic baggy full of tiny screwdrivers, for me to take one
I asked if they're t5
the shape looked right, but I can't tell the size
I took one out and tried to find size marking, but nothing
he didn't seem to know what I was asking when I asked about its size
he said if it's wrong I can come back and trade what I took for another. lol
I asked him if I can buy it, since that wasn't evident to me due to how sus this random bag of screws is being thwarted on me lmao
he said 5$ cash
I gave him a fiver
this sus shop literally avoiding taxes lmao
walked back home, ate food cuz starving, tried the screw and FUCK, it's too big. put laptop in a bag and hauled ass fast, checked on maps the store I got this from closes in a few minutes so I really wanted to make it there because what if the receptionist changes and they don't know I took this screw. I got no receipt
got there right before closing, put my laptop down, said it was too big. he used a few screws until he found one that fit, said I could try it and I did (so scam aware!). bingo bango. now I got a screwdriver that fits the laptop.
walked home, sat down and took apart the laptop. been a few years since I did so. the hardware inside looks entirely unrecognizable to me. started cycling through YouTube videos of laptops of the same name as mine, but their insides don't look like mine. is this ram? is this the NVMe? what the fuck is anything?
finally found a video guide where the guy was quite informative. not the same laptop but he's informative enough I figure it out. ram and drives are so different and weird now. took parts out, put them back in, rebuilt laptop, tried to boot, same problem. jiggling parts like this works with desktops often, guess not with a failed NVMe
so I'm screwed. get on Newegg and bought a new NVMe. should arrive in 3 days via Purolator
yesterday was day 3. it was at a sort facility near me, then out on delivery, but nobody ever came. then it went back to sorting. now it's out on delivery again. I'm sitting here thinking that's a little weird, wasn't Purolator the delivery company that had me go 2 hours outside of town to pick up a 15lb desktop case once?
... and then I looked up Reddit comments... then reviews on the purolator facility it's at... I am screwed. last time iirc they were out for delivery for 3 days, never tried delivery, then on the last day at the end of day they stated they attempted delivery but no go. that was bullshit. then it ended up at that facility. which takes 2 hours to fucking reach.
the reviews are so bad... the facility has 1.2 star reviews with thousands of them. they won't leave even a stub, then seem to not know where your package is at the facility, or they deny you have the right to pick it up despite ample IDs, or someone ELSE picks it up and it's not there. they also ship your package back after 5 days, so if they don't leave a note and you miss it tough luck...
fucking hell
also rumours that they just hire "contractors" in normal cars to drop off packages? wat? lol
AND EVERY REVIEW HAS A BOT COMMENT. THEIR SUPPORT IS JUST A CHATBOT
I thought this was just a small hiccup
I think I might not have a drive for weeks now
fucking hell
now I'm sitting on my porch2 -
When you hear “Haskell performance”, what comes to your mind? I was never really interested in Haskell since I had Clojure, and I thought Haskell might be slow.
Haskell with GHC is actually as fast as C or even faster. Haskell runs right on your hardware, no VM or interpreter.
When a program is small, the performance is comparable to C. Sometimes it’s quicker, sometimes not. But when a program is large, Haskell implementation would be faster if you’re not a robot that generates perfect C code.
It’s both very high-order AND very fast. You don’t need math to code in Haskell.
Too bad there are no kewl libraries.12 -
Just received code review from interview technical task. 50 percent of it was because of encapsulation (that 5-8 variables could have been private instead of public). 20 percent was about shit that was expected but missing (error validation, dependency injection). It was missing because it was not specified in app requirements and also noone said that I have to build a production level application for a simple interview here. 10 percent was nitpicking about formatting(I used default intellij formatter) and one ide error that appeared because of project importing. And only 20 percent of feedback was actually constructive and useful. Cool. Also developer said that he was shocked that I made loading animation but didnt call it in my app. However I made it, but if you have fast internet connection it doesnt show up. I mean if you run my app on a phone with gprs connection u will see that damn animation. What Im supposed to do slow down the app so u could see it? But we are building production level app here no? Shit. It feels like he applied double standards to me or something. Half of review nitpicking about useless details and another half about shit that is expected to be in the app but was not even communicated. Also I did not get developers contact so I could ask him what the fck he wanted from me.1

tell me guys what would you prefer:
function a(){
..
b(..)
..
b(..)
..
}
function b(p1,p2,p3,p4,p5,p6){.
...
}
or
function a(){
..
b(..)
..
b(..)
..
}
function b(
p1,
p2,
p3,
p4,
p5,
p6
){
...
}
if you read this rant before expanding, you got a complete context on how what function a is, its calling b 2 times and how function b looks.
if instead of the first option, i had used 2nd block, you wouldn't even know the 2nd param of b function without expanding this rant.
my point?
i prefer to keeping unnecessary info on one line. and w lot of linters disagree by splitting up the code. and most importantly , my arrogant tl disagree by saying he prefers the splitted code "for readability" and becaue "he likes code this way, old-eng1 likes this and old-eng2 likes this" .
why tf does an ide have horizontal a scrolling option available when you are too stupid to use it?
ok, i know some smartass is going to point that i too can use vertical scrolling, but hear me out: i am optimising this!
case 1 : a function with 7 params is NOT split into 7 lines. lets calculate the effort to remember it
- since all params could have similar charactersticks ( they will be of some type, might have defaults, might be a suspendable/async function etc), each param will take similar memory-efforts points. say 5sp each.
- total memory-efforts= 5sp *7 = 35 sp.
- say a human has 100 sp of fast memory storage, he can use the remaining 65 sp for loading say 5 small lines above or below.
- but since 5 lines above are already read and still visible on screen, they won't be needed to be loaded again nd again, nd we can just check the lines below.
- thus we are able to store 65+35+65 = 165 sp or about 11 lines of code in out fast memory for just a 100sp brain storage
case 2 function with 7 params IS split into 7 lines.
- in this case all lines are somewhat similar. 5sp for param lines as they are still similar which implies same 35sp for storing current function and params
- remaining 65sp can only be used to store next 5 lines of 13sp as the previous code is no longer visible.
- plus if you wanna refresh the code above, you gotta scroll, which will result in removing bottom code from screen , and now your 65sp from bottom code is overwritten by 65sp of top code.
- thus at a time, you are storing only 6 lines worth of code info. this makes you slow.
this is some imaginary math, but i believe it works10 -
So at my last job we had an AM deployment and a PM deployment. We had code reviews, QA, a slow roll process (deployed to three servers), monitoring process, and once everything checked out we fast rolled to the other servers.
At my current job we have a QA process, and we deploy once every three weeks.
My first job I deployed as needed, with no QA at all (I was the only web dev there).
I'm currently at a major e-commerce site, my last job was more of a click-bait site (though it still made millions in revenue each year).
So my question is: is there a "normal" as far as deployment schedules? I realize that each business type is going to have their own needs, but what's the "average" time between deployments?
