*Rules For Work*
1. Never give me work in the morning. Always wait until 4:00 and then bring it to me. The challenge of a deadline is refreshing.
2. If it's really a rush job, run in and interrupt me every 10 minutes to inquire how it's going. That helps. Even better, hover behind me, and advise me at every keystroke.
3. Always leave without telling anyone where you're going. It gives me a chance to be creative when someone asks where you are.
4. If my arms are full of papers, boxes, books, or supplies, don't open the door for me. I need to learn how to function as a paraplegic and opening doors with no arms is good training in case I should ever be injured and lose all use of my limbs.
5. If you give me more than one job to do, don't tell me which is priority. I am psychic.
6. Do your best to keep me late. I adore this office and really have nowhere to go or anything to do. I have no life beyond work.
7. If a job I do pleases you, keep it a secret. If that gets out, it could mean a promotion.
8. If you don't like my work, tell everyone. I like my name to be popular in conversations. I was born to be whipped.
9. If you have special instructions for a job, don't write them down. In fact, save them until the job is almost done. No use confusing me with useful information.
10. Never introduce me to the people you're with. I have no right to know anything. In the corporate food chain, I am plankton. When you refer to them later, my shrewd deductions will identify them.
11. Be nice to me only when the job I'm doing for you could really change your life and send you straight to manager's hell.
12. Tell me all your little problems. No one else has any and it's nice to know someone is less fortunate. I especially like the story about having to pay so many taxes on the bonus check you received for being such a good manager.
13. Wait until my yearly review and THEN tell me what my goals SHOULD have been. Give me a mediocre performance rating with a cost of living increase. I'm not here for the money anyway.

Write a small js function using setInterval to fire a request every second ... then copy paste the code 450 times (literally, not an exaggeration) into a massive file to create a load test script.
This load test script also had no means to gather metrics or test response times or anything useful. It was literally a “did the server crash” test.9 -
New JS arrow functions:
⇶ (“the gun rack”) – executes three times
↝ (“wiggly boi”) – finds the least efficient solution possible
⟳ (“the self-monch”) – executes forever
⍆ (“🤷”) – adds random side effects
⍅ (“the total and complete s**t”) – undoes the only useful and expected part of its execution
Absolutely hilarious 😆

I have a lot of interesting code snippets from some kind of inhouse CRM/billing software, but for now let's look at this very useful PHP function.4
-
Share your most useful terminal aliases and functions.
alias gs='git status'
alias gcm='git commit -m'
alias push='git push'
alias pull='git pull'
alias hosts='sudo nano /etc/hosts'
alias glog='git log --graph --oneline --decorate -n 10 --color'
alias mykey='cat ~/.ssh/id_rsa.pub | xclip -sel clip'
function mkcd () {
mkdir -p -- "$1" && cd -P -- "$1"
}
As well as one for each major project (lets say 1+ weeks of dev time) to immediately cd to it from anywhere. How about you guys?
Always looking to improve my terminal commands, so am curious what everyone else uses for shortcuts.27 -
I hate myself. Really.
Last week I wrote a function to handle file uploads and at some point I left this very useful comment.
Do I know what to fix? Absolutely fucking nope.
I want to punch me from last week in the face9 -
Yo!
I went to see my mother a few days, and her TV's broken.
She told me to repair it, because "you're a programmer"
Does anybody knows a python function or a useful library that could repair TV ?5 -
I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.
Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.20 -
I can't help but be disappointed in the direction that technology has directed us into, especially social media.
While I love my girlfriend, she more often than not spends her time scrolling away at the dumbest shit on Instagram, Facebook, .. reels. Reels everywhere. And she's not dumb, mind you. She's an engineer just as much as you (presumably) and I are. Just in a different field.
When looking into it online and stumbling upon more than one study, I learned about the term it had been coined.. technoference. That's the constant interruption of social media into our day-to-day lives, and the dopamine kick it gives -- more so than IRL peers do. Why that is, being the digital equivalent to McDonald's, that's beyond me. But somehow it seems to be better, all while the content isn't even useful. It doesn't allow you to learn anything, to gain insights, or to explore things that could serve you in the real world. Cat videos and random shit that's somehow.. funny? Having pretty much completely disconnected from social media years ago, I seriously fail to see how.
Maybe us nerds in the 90's and early 2000's telling everyone else how we'd change the world and prove everyone who called us freaks wrong, disenchanted as we were (and probably still are), were the catalyst for this social disaster. We had the cognitive skills to do it, but not the social equivalent. I feel guilty... Even though I've always been part of a big tech resistance in some capacity, I still feel guilty. Because I'm one of those people with the skills of those who created this trash fire of a societal status quo. Everyone glued to their screens, 95% of the time not for work. Not even to aid one's ability to function in the real world. Just to combat boredom. All day, for many hours on end.
Where is it going to end? When will people realize the dystopia we got ourselves into? Will anyone but a few fight it? Would those who don't fight it even care?11 -
I messaged a professor at MIT and surprisingly got a response back.
He told me that "generating primes deterministically is a solved problem" and he would be very surprised if what I wrote beat wheel factorization, but that he would be interested if it did.
It didnt when he messaged me.
It does now.
Tested on primes up to 26 digits.
Current time tends to be 1-100th to 2-100th of a second.
Seems to be steady.
First n=1million digits *always* returns false for composites, while for primes the rate is 56% true vs false, and now that I've made it faster, I'm fairly certain I can get it to 100% accuracy.
In fact what I'm thinking I'll do is generate a random semiprime using the suspected prime, map it over to some other factor tree using the variation on modular expotentiation several of us on devrant stumbled on, and then see if it still factors. If it does then we know the number in question is prime. And because we know the factor in question, the semiprime mapping function doesnt require any additional searching or iterations.
The false negative rate, I think goes to zero the larger the prime from what I can see. But it wont be an issue if I'm right about the accuracy being correctable.
I'd like to thank the professor for the challenge. He also shared a bunch of useful links.
That ones a rare bird.21 -
Fuck off cancerous piece of shit on stackoverflow whose dick is an obvious inverse proposition to ego and incapablility to read.
I asked if there's "clean" way, of doing something. I provided my solution to the problem
Your answer and coments make it pretty obvious that you:
* don't really care about (code) quality
* value your reputation just as much as some teen on facebook sucking cook for likes or whatever they use now
* downvoted my question because you can't handle critique in the slightest
* You immediately replied with "but op said..." even though I am the fucking op and if I say _imo_ a fucking for-loop within function is less readable than 3 chained function-calls it and does not include the feature I asked for, it means you have to justify your answer and not get triggered and downvote my fucking question.
After I confronted him about this shit he just said "If you had studied the language for more than 10 minutes you would have known than you can't do that."
And if you had some a basic reading skill you could improve my workaround or tell me just that, instead of providing me with that useless information you vomited out just to get some ez SO reputation.
Piece of shit didn't even deny the anyyhing.
Shove a vibrator up your ass until it arrives at your skull and activate it. Maybe that will stimulate your brain or hopefully upgrade it.
I don't care how much "reputition" you may have "earned" on the internet. I am not afraid to call your bullshit or your sheer pathetic existence out.
People like this are are the reason SO gets so much hsge and even tough I got an improved version for my workaround (from an other user), I'm nowhere near happiness.
Note, the Useful-to-retarded-ratio is

I just lost faith in the entire management team of the company I'm working for.
Context: A mid sized company with
- a software engineering departmant consisting of several teams working on a variety of products and projects.
- a project management department with a bunch of project managers that mostly don't know shit about software development or technical details of the products created by engineering.
Project management is unhappy about the fact that software engineering practically never sticks to the plan regarding cost, time and function that was made at the very beginning of the project. Oh really? Since when does waterfall project management work well? As such they worked out a great idea how to improve the situation: They're going to implement *Shopfloor Management*!
Ever heared about Shopfloor Management? Probably not, because it is meant for improving repetitive workflows like assembly line work. In a nutshell it works by collecting key figures, detecting deviation in these numbers and performing targeted optimization of identified problem areas. Of course, there is more to Shopfloor Management, but that refers largely to the way the process just described is to be carried out (using visualisation boards, treating the employee well, let them solve the actual problem instead of management, and so on...). In any case, this process is not useful for highly complex and hard-to-predict workflows like software development.
That's like trying to improve a book author's output by measuring lines of text per day and fixing deviations in observed numbers with a wrench.
Why the hell don't they simply implement something proven like Scrum? Probably because they're affraid of losing control, affraid of self managed employees, affraid of the day everybody realizes that certain management layers are useless overhead that don't help in generating value but only bloat.
Fun times ahead!8 -
So I would really like to see a devrant like app where devs can share design ideas for problems that are greater than a function call, or topical questions found on stack overflow.
As I have gotten older, I have realized that actual implementation is typically easy, the design approach is typically harder to get right from the first go, so open critique can be very useful.6 -
Definitely Rust, and a bit Haskell.
Rust has made me much more conscious of data ownership through a program, to the point that any C/C++ function I wrote that takes a pointer nowadays gets a comment on ownership.
I wish it was a bit less pedantic about generics sometimes, which is why I've started working on a "less pedantic rust", where generics are done through multiple dispatch à la Julia, but still monomorphising everything I can. I've only started this week, but I already have a tokenizer and most of the type inference system (an SLD tree) ready. Next up is the borrow checker and parsing the tokenized input to whatever the type inference and borrow checker need to work with, and of course actual code generation...
Haskell is my first FP language, and introduced me to some FP patterns which, turns out, are super useful even with less FP languages. -
Well... I had in over 15 years of programming a lot of PHP / HTML projects where I asked myself: What psychopath could have written this?
(PHP haters: Just go trolling somewhere else...)
In my current project I've "inherited" a project which was running around ~ 15 years. Code Base looked solid to me... (Article system for ERP, huge company / branches system, lot of other modules for internal use... All in all: Not small.)
The original goal was to port to PHP 7 and to give it a fresh layout. Seemed doable...
The first days passed by - porting to an asset system, cleaning up the base system (login / logout / session & cookies... you know the drill).
And that was where it all went haywire.
I really have no clue how someone could have been so ignorant to not even think twice before setting cookies or doing other "header related" stuff without at least checking the result codes...
Basically the authentication / permission system was fully fucked up. It relied on redirecting the user via header modification to the login page with an error set in a GET variable...
Uh boy. That ain't funny.
Ported to session flash messages, checked if headers were sent, hard exit otherwise - redirect.
But then I got to the first layers of the whole "OOP class" related shit...
It's basically "whack a mole".
Whoever wrote this, was as dumb and as ignorant to build up a daisy chain of commands for fixing corner cases of corner cases of the regular command... If you don't understand what I mean, take the following example:
Permissions are based on group (accumulation of single permissions) and single permissions - to get all permissions from a user, you need to fetch both and build a unique array.
Well... The "names" for permissions are not unique. I'd never expected to be someone to be so stupid. Yes. You could have two permissions name "article_search" - while relying on uniqueness.
All in all all permissions are fetched once for lifetime of script and stored to a cache...
To fix this corner case… There is another function that fetches the results from the cache and returns simply "one" of the rights (getting permission array).
In case you need to get the ID of the other (yes... two identifiers used in the project for permissions - name and ID (auto increment key))...
Let's write another function on top of the function on top of the function.
My brain is seriously in deep fried mode.
Untangling this mess is basically like getting pumped up with pain killers and trying to solve logic riddles - it just doesn't work....
So... From redesigning and porting from PHP 7 I'm basically rewriting the whole base system to MVC, porting and touching every script, untangling this dumb shit of "functions" / "OOP" [or whatever you call this garbage] and then hoping everything works...
A huge thanks to AURA. http://auraphp.com/
It's incredibily useful in this case, as it has no dependencies and makes it very easy to get a solid ground without writing a whole framework by myself.
Amen.2 -
I've been lurking on devrant a while now, I figure it's time to add my first rant.
Little background and setting a frame of reference for the rant: I'm currently a software engineer in the bioinformatics field. I have a computer science background whereas a vast majority of those around me, especially other devs, are people with little to no formal computer background - mostly biology in some form or another. Now, this said, a lot of the other devs are excellent developers, but some are as bad as you could imagine.
I started at a new company in April. About a month after joining a dev who worked there left, and I inherited the pipeline he maintained. Primarily 3 perl scripts (yes, perl, welcome to bioinformatics, especially when it comes to legacy code like is seen in this pipeline) that mostly copied and generated some files and reports in different places. No biggie, until I really dove in.
This dev, which I barely feel he deserves to be called, is a biology major turned computer developer. He was hired at this company and learned to program on the job. That being said, I give him a bit of a pass as I'm sure he did not have had an adequate support structure to teach him any better, but still, some of this is BS.
One final note: not all of the code, especially a lot of the stupid logic, in this pipeline was developed by this other dev. A lot of it he adopted himself. However, he did nothing about it either, so I put fault on him.
Now, let's start.
1. perl - yay bioinformatics
2. Redundant code. Like, you literally copied 200+ lines of code into a function to change 3 lines in that code for a different condition, and added if(condition) {function();} else {existing code;}?? Seriously??
3. Whitesmiths indentation style.. why? Just, why? Fuck off with that. Where did you learn that and why do you insist on using it??
4. Mixing of whitesmiths and more common K&R indentation.
5. Fucked indentation. Code either not indented and even some code indented THE WRONG WAY
6. 10+ indentation levels. This, not "terrible" normally, but imagine this with the last 3 points. Cannot follow the code at freaking all.
7. Stupid logic. Like, for example, check if a string has a comma in it. If it does, split the string on the comma and push everything to an array. If not, just push the string to the array.... You, you know you can just split the string on the comma and push it, right?? If there is no comma it will be an array containing the original string.. Why the fuck did you think you needed to add a condition for that??
8. Functions that are called to set values in global variables, arrays, and hashes.. function has like 5 lines in it and is called in 2 locations. Just keep that code in place!
9. 50+ global variables/hashes/arrays in one of the scripts with no clear way to tell how/when values are set nor what they are used for.
10. Non-descriptive names for everything
11. Next to no comments in the code. What comments there are are barely useful.
12. No documentation
There's more, but this is all I can think to identify right now. All together these issues have made this pipeline the pinnacle of all the garbage that I've had to work on.
Attaching some screenshots of just a tiny fraction of the code to show some of the crap I'm talking about.6 -
...i just remembered why I have a MasturbatorPattern repository on my bitbucket, why is it named that way, and what it does.
It's one of the core abilities of that magical AI i've mentioned in my previous rant. And it's called that way, because of how it works:
The Agent has some objects (as in, class instances) available to it, and wants to get some other kind of object. So it inspects by reflection ("touches") all objects around itself, inspecting their public functions, building up a plan/path/tree of "this function takes the object I have as input, and returns this other object which this other function of other object takes as input and returns this different object, which...." etc, etc, until the final function returns the object the Agent wanted to get in the first place.
And then it goes and "does" all those functions, in that order piping the parameters through.
So first it touches them (second layer of metaphor - linux finger command), and then it does those which output (ejaculate =D) something useful to it.
Therefore, MasturbatorPattern =D
Not sure if my sense of humor is just weird or outright unfunny.8 -
I started my internship at the end of the year..
Fuck my ass!!! This code I have to work with is a huge pile of shit.
The code base I need to work with is around 40k LOC. It is a mixture of C++, C, Java, Python, Bash and I think I saw some lonely js files around.
A list of awesome parts:
- Paths are hard coded.
- Redundant code everywhere
- No documentation or inline comments available
Most of the comments in the code are just old code that is not used anymore. But the cherry on the turd is the class that should provide all kind of useful functions in my daily routine. About ninety percent of the functions have the same description or nothing. Sometimes a function name says "readSomethingFromSomewhere" but instead it writes something to a file. It is really confusing and I need to check everything twice instead of rely on what the function name promises.
I have also learned why copy paste isn't that good. The brief descriptions of every method in a files are always the same.
getName() - Description: Fork child process
getIp() - Description: Fork child process
getIpv6() - Description: Fork child process.
Surprise: None of these functions forks a child process. :D
Another awesome feature is the thing that they store up to five different versions of libraries. Everyone with slight modifications but no hint which one you need to use. Sometimes it is the newest, sometimes the oldest which is running in production. Another case of try and error.
Oh and my dev machine is a potato with a power supply and a fan. I started with NetBeans and every time I compiled the code it sounds like the machine wants to lift off and leave for a better place. (At this point I switched to Emacs and everything runs smoothly now)
At first I thought that I'm just not that good at coding and understanding a big project from scratch but some colleagues have the same problem. The whole system is very inflexible and it is all about "std::cout"-debugging to check if your changes do what you want them to do.
Currently I'm just trying to fix this mess to make the life for the next student or employee easier. The first month was just frustrating as hell. I need to ask so many questions and most of the time the answer was "I don't know, haven't touched this code in years". Needless to say that my progress isn't that awesome but at least I get a nice payment for 20 hours of work a week.2 -
You may remember a super long time ago I double-buffered the Windows cmd.exe using c++
tl;dr, here it is in c!
Anyways, I was still learning c++ back then. It wasn't my first project in c++ but it was close and I ran into a lot of issues. The thing worked... but only if you didn't touch it.
Here's the same project (With a lot less bells'n'whistles) written in c. I used a different approach this time, and other than my function naming convention (Which, I honestly don't even know if it's bad or not!), I think this is some pretty solid code!
In the image you see the header file (I used as a summary of the code) and then three x's in a terminal. To do this, the code:
-Creates a ConsoleScreenBuffer handle
-Creates two CHAR_INFO buffers for drawing & displaying
-Draws three x's to the draw buffer
-Copies the draw buffer to the display buffer
-Copies the display buffer to the ConsoleScreenBuffer handle
I'm thinking about cutting out the middle man and removing the display buffer (which holds what is currently displayed) but I think it may actually be useful, and I don't know.
Anyways, I have no friends that understand this stuff so that's why it's here. Cheers.3 -
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 wrote this and wonder if it is actually useful. This is a function that eliminates the need for document.getElementById. In the HTML you just set an attribute (jsv) to some value and this scoops that up and puts it in the global scope for you to use.
Neat or shit?12 -
Most succesful project was around this time last year.
A scary club of privacy haters made a 'webapp' to advise people what to vote for in the national elections.
The tool was really bad in multiple ways. For instance, if two parties would score the same amount of points, one would, at random take second place without conveying this to the user.
Oh and it also collected all the data people entered "for scientific purposes". A very sketchy practice, a non profit, funded by the government and George Soros (I kid you not, illuminatie confirmed ;) ).
The tool had this disclaimer on the bottom, saying this webapp needs cookies to function. So that triggered me to make a copy of the tool that works better and ... offline, and without cookies. You could download a html file and turn of your wifi (for the paranoid ppl among us), use the tool, delete the file. No trace.
It was a little bit of tung and cheek project, a gimick, the original was called stemwijzer, mine was called offline stemwijzer.
It was a one day build and a day after launching I got a call of the original stemwijzer project leader. Demanding to take the thing offline for infringing copyright (yeah sort of was). I tried to explain him why I made this and why privacy for such things should be held in high regard. He basicly told me I was talking shit and did not want to discuss, I told him I don't take stuff offline because of phone calls. I told him to email me a seist and desist.
So that guy prolly had a stressful day (because of the launch of his tool), had a few glasses of wine, and wrote an email. He wrote me I was a pathtic kid and I should do more useful stuff. He wrote that anyone could program a tool like that. And he wrote me I should do him a favour not share this email with my measly amount of twitter followers. Super professional email.
So I did him that favour, I did not share it with my twitter followers, I shared it with one of the largest political blogs in the country.
My tool sort of took of after that. To stop infringing copy right I changed the name and I removed their content from the script and wrote instructions on how to copy and paste in the json content yourself and "make your own tool".
The response was great, people actually emailed me job offers and I think that the current job I have is due to the succes of said project. So be balsy, challenge giants, start riots, it will get you places.2 -

I'd just like to interject for a moment. What you're refering to as windows, is in fact, NSA/windows, or as I've recently taken to calling it, NSA plus Windows. Windows is not an operating system unto itself, but rather another free component of a fully functioning NSA system made useful by the NSA corelibs, spyware and data collection system components comprising a full surveillance system.
Many computer users run a modified version of the NSA system every day, without realizing it. Through a peculiar turn of events, the version of the NSA data collection system which is widely used today is often called Windows, and many of its users are not aware that it is basically the NSA system, developed by the NSA.
There really is a Windows, and these people are using it, but it is just a part of the system they use. Windows is the piece of trash: the program in the system that steals the system resources from the other programs that you run. This piece of crap is an essential part of an NSA system, but useless in practice; it can only function in the context of a complete NSA system. Windows is normally used in combination with the NSA surveilance system: the whole system is basically NSA with Windows added, or NSA/Windows. All the so-called Windows systems are really distributions of NSA/Windows!

Boy was I happy to see this when I opened devRant up.
So for starters, more group projects are necessary. Many reasons why. To begin with, it allows for more complex programs than getting some input and printing some shit out. It also develops interpersonal skills (I hate people too, but when you go out to look for work you'll be with them, so better get used to it soon). If a platform like GitHub is used, it's easy to track who did what, and see what each person in the group did, so it should be fairly easy to discourage lazy asses.
Beyond that, stop giving us half completed assignments and asking us to fill in a function/method. Yes, it will take longer. But one doesn't learn to program by doing the minimum required work, you've got to crash and burn a lot in order to git gud. So ffs, let us do all the work. We're like AI, we learn through reinforcement learning.
Stop giving us a spec to follow. We'll do plenty of that in the future, right now we need to make mistakes, not be held by the hand all the way. Let us do dumb shit so you can fail us and tell us our code is repulsive, and this other way was better. Explain why. That's how people learn, not by telling us what each function should return, what can and can't be used, etc. And if you can't come up with a scenario in which what you're teaching is useful, then maybe you're not teaching us the right material.
I'll leave it at that for today... But I'll be back 😈 -
in college ages ago, professor was "teaching" us overloading in C++, he goes something like this:
"so you can overload a function by changing the number of arguments, argument types, or method return type"
I dare put my hand up: "emm .. you can't overload by just changing the return type"
"you can"
"but, but.. how would the compiler know which overload I'm invoking when I call the method?"
pause..
"it depends on the type of the variable receiving the method call result"
"what if I call the method without assigning the result to a variable?"
agitated by now: "ah these are complex compiler concepts that are too complicated blah blah"
although I was unhappy, it was useful to realize no one knows everything5 -
I was working on a thing at work which routes http requests from one endpoint and port to several local services.
I was halfway done when I noticed I just wrote a primitive reverse proxy.
Anyway, I'm calling it GRID, Gateway for REST Interface Distribution.
It's capable of dynamically attaching new routes and services and removing those during runtime via inbuilt typescript compilation service.
Each "runtime module" defines several routes which may have a middleware function (express.js style), which gets executed before forwarding the request to the local service.
I don't know why, but I'm kinda proud of this one; Feels like I made something actually useful for once.
Gonna maybe add a webUI with the monaco editor to write typescript modules without needing VSCode...
Also I may implement a load balancing system for scalability.
It comes with a cli too.
Gonna put it on github and post it here once I'm done with v1.19 -
It’s actually been quite a fun day, after some ranting on one of our slack communities flutter channel, myself and my team realized we were in a really good place to give back.
We have been working on a large scale flutter application for about a year, phase 1 is about done and we at 11k LOC.
We have been doing a big push for testing over the last 2 months and are at about 50% coverage. The thing we realized is that is the 1 place flutter has fallen short with documentation.
Very little about what we learned for testing our code came out of a google search, or it came out of cobbling bits together from numerous searches and sources.
So we decided we are going to plan and host a virtual meetup to discuss what we have learned and hopefully teach a few people some useful things and hopefully also learn a few new things too.
In addition, and as it has a longer shelf life, we going to setup a medium publication for the company and start a series to cover small specific topics, specific use cases or scenarios that we had trouble with and solved.
Today I had my first thing to type out, had worked out how to test that a function that was passed into a widget was called. So the parent passes the child and onTap function but you are testing the child not the parent as the child is reusable...
Anyway, so with that idea I got hold of marketing for some assets, setup the publication and proceeded to type out 3 articles today, all nice short ones under 2 min reading time.
It really is nice to give back, it’s not like I am Remi smart and can go and write BLoC, but I am smart enough to figure shit out and type it up so that the next guy hopefully benefits from my brain bashing.6 -
I'd just like to interject for a moment. What you’re referring to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called “Linux”, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use.
Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux.9 -
Fuck Wordpress, Fuck Wordpress's PHP
I'm so fucking tired of everything in this godforsaken CMS. Import a JS File? Sure, just add a *completely obvious* line into a very specific PHP File, where you'll have to specify a lot of "useful" parameters. No, I somehow DON'T want to specify that I don't wand jQuery in every import. And don't even get me started on Content Delivering. Embed CSS? Sure, just write the fucking whole path to the file, or use the broken get_stylesheet_uri() Function. Embed an Image? Sure, let me just go to the Backend and wait 6 Minutes for this bullshitty System to upload the image and then copy the hard-coded Link. Oh, you want to remove googleapi embeds? Sure, let me just fuck up your whole Website in return.
You want jQuery? Well instead of using the "$" Symbol, you have to use the jQuery() Function. Except when you don't have to, which is 100% random each time you reload the page. Oh, you actually did import a JS File? Sure, let me just not run it. Thank you fucking piece of shit thats calling itself "WordPress" and fuck you and everyone whos actively encouraging its usage1 -
Chemists recently "compiled" a programming language into chemicals! I'll admit that I have no clue how it works, but they were able to get a mathematical function working without any electronics. The article I read doesn't describe the speed of the reaction, so I'm not sure if it's really useful as a replacement for computer operations.4

I'm a C++/Obj-C programmer finding it ludicrously hard to switch to Swift.
I find that the constant ability (leading to very poor programmer code) to reduce syntax and add tokens reduces readability and nowhere is this more apparent that with closures.
I'm working through (to my shame) Ray Wenderlich's Swift course and the closure chapter has this:
PS I loathe K&R as much as I do Swift so it's all in Allman formatting for clarity.
let multiply: (Int, Int) -> Int =
{
(a: Int, b: Int) -> Int in
// do Something else
return a * b
}
Why oh why isn't this more simply and elegantly written as:
let multiply = (a: Int, b: Int) -> Int
{
// do Something else
return a * b
}
The equals sign shows clearly that it's a closure definition assignment, as does the starting 'let'. But this way all of the stupid excesses, like the 'in' keyword, the repetition of the params / return type only this time with useful labels and additional tokens are removed and it looks and reads much more like a regular function and certainly a lot more clearly.
Now I know that with the stupid ability of Swift you can reduce all this down to return $0 * $1, but the point I'm making is that a) that's not as clear and more importantly b) if this closure does something more than just one line of code, then all that complicated stuff - hinted to by the comment '// do Something else' means you can't reduce it to stupid tokens.
So, when you have a clousure that has a lot of stuff going on and you can't reduce it to stupid minimalism, then why isn't is formatted and syntactically better like the suggestion above?
I've mentioned this on the Swift.org (and got banned for criticising Swift) but the suggestions they came up with were 'use type inference' to remove the first set of params / return type and token.
But that still means the param list and return type are NOT on the same line as the declaration and you still need the stupid 'in' keyword!5 -
Okay but whys no one talking about w3js? Its not a complete overhaul of the entire frontend shit, it doesnt introduce fucked up concepts, it literally just abstracts away those 10 functions everyone creates a function for in the first 2 minutes either way, its actually useful.1

So I see posts about an interview question/challenge of inverting a binary tree. I don't use trees very often (mainly file related or parsing server nodes), but I thought I would learn how to do this.
I saw a page that started talking about different ways to invert enough to understand that one type of inversion is swapping left and right nodes. So I stopped before they showed how.
Then I created a test program that has a tree structure and also can display a tree before and after modification. This was kind of fun.
So then I wrote the inversion function. It was less than 10 lines of code. Wtf? I thought it would be harder than this.
Then I started wondering where trees were used. So today I have been learning how they are used and why I might need one to solve a problem. One use I intuited was parsing regex or a language. Apparently it is useful there.
What I am learning is that a lot of these interview questions are really test to see if you can comprehend instructions when stressed. Or you will ask questions to clarify the task. It doesn't necessarily test your ability to solve hard problems.
One thing that perplexes me. If inverting a tree is swapping nodes left<->right, then why not leave data in place and just swap roles in the functions. Maybe I completely misunderstood what inversion means or why it would be done. I guess if this is not inverting I have the structure to try other methods now.2 -
How resource calculations for software services like code analysis, monitoring, etc are done:
Opening fridge, putting all the beer one can find in it.
Opening the necessary tools, e.g Excel, Accounting software, ....
Drinking the first beer.
Starting to aggregate the monthly costs - cause you can never trust the reports written by someone else...
First beer poof.
Looking at the monthly cost, adding columns "Intended use", "Actual usage pattern", "Usage factor"...
Opening next beer...
Usage factor is btw a factor of 0.1 ... 1.0 - to give an estimate how much the products feature are actually used, for further analysis if the invest is justified or not...
Oh. Another half bottle gone...
Filling in the columns...
Oh. Bottle empty and the next one toooooooooooooooo...
*burping*
*cracking finger joints*
Now let's get to the sad part...
Next worksheet, adding infrastructure costs...
Cost and description as columns.
Hehe. Column sounds like gollum.
Another beer...
Ugh. Need the paper reports, manually typing off things for stuff that was e.g. tax deductible.
Many beers die during this task. Poor little beers, dying for such an boring and mundane task...
SUM is a real useful function. I don't think I can add numbers anymore.
Now we can add another sheet.
Hehe. Sheet sounds like shit. And yes, everything in this file is shit.
Summing up costs from both sheets and including the cost factor from 1
... Beeeeeeeer Beeeeer beer we need more beer here... Beer beer beer...
Where was I. Oh yeah. Cost factorization total vs effective.
Why do I want to get even more drunk.
Oh yeah. Most software is completely underused and the costs aren't justified.
Let's add some colored highlighting ...
Uuuuh. ,Too much red. Better change the highlights.
Too much red.
More beer.
Don't give a fuck.
Hm.
Time for some whiskey.
What else is there to do....
Oh yeah.
Diagrams.
The bloody wankers from accounting need diagrams as numbers are too boring.
Not that everything in accounting is boring, no matter how much you paint colors on it... *sigh*
Hm. More whiskey...
Hehe. Whiskey rhymes with frisky.
Uff. Now just need to write mail. Mail mail mail....
"Copy paste the last mail from last month"
Hm.
Ah.
*sipping whiskey*
Spell check extension - to the rescue.
Thesaurus *burps*.
Let's change a few words here and there... Maybe another paragraph there.
Uh....
Trying to attach file...
*fucking mouse is pretty constantly crashing into empty beer bottles*
Done.
Damn.
Need to press send button.
*Creating mess on the desk by just randomly crashing the beer bottles*
Done.
*Pressing computers power button*
Mwahahahaha. No mouse needed.
*regretting to stand up too quickly, nearly barfing on the floor*
Couch ... Where Couch...
After hitting several doors, frames and other stuff, the glorious mission ended successfully with a most graciously executed gut buster on the couch.

at one point documents were useful things to align people to the relevant information to the tasks they must complete for everything to work out
now documents are a ritual, and relevant information is even forgotten or omitted and considered secondary to the document existing and looking like a professional document
I wonder if this is how all industries evolve
at one point there were people who knew what they were doing, they created processes so nobody is left behind
and over time, whoever made the processes, the spirit for their existence, is forgotten
and you're left with empty rituals, so devoid of their original function, the humans subjected to these things, crushed by them, can't even discern what their usage is
evidently if you put monkeys in an enclosure with some apples up a tree with a mechanism that if a monkey goes up the tree and takes an apple it sprays all the other monkeys in the enclosure with water
the monkeys will learn to pull down any monkey trying to go up the tree, because they don't wanna get sprayed
and this will keep going, generations will change and yet they'll still religiously pull down the monkeys, in a ritual... nobody remembers why only that their parents did this to them, so they do it to others
if you take the trap away, they never figure it out, which is how this story is typically told
but regardless of if the trap is there or not
wouldn't you wanna know and see it for yourself instead of following empty rituals?!
and what of people who erroneously view things as traps, and pull people down, but they were just seeing things?!
self limiting myths to doom the ages! -

Maybe a usefull function for the fellow developers here, in case you need default Avatars for your users. "UI-Avatars". Just 'discovered' this beautiful API today and it really is easy and helpful! :D It even has a PHP package if you would like to generate them yourself.. This is not an ad or anything, it's just a usefull API, like 'placehold.it' etc that could be useful for anyone out there! -
Way of wasting time:
generating csv and importing in Open Office Calc, mysteriously what should be ",-," shows as "-0".
I thought some strange fucking time function was responsible of generating a "0" after my "-", until I discovered that for some fucking reason, Open Office Calc decides to add the fucking "0" by itself.
And they say that computer do what they are told to. I just said to import a fucking "-", it's called "Minus". do you fucking understand Calc?
Back to something useful.1 -
What baffles me is how despite being on version 3 of Swift, Apple still havent updated Xcodes refactoring tools to support it. All I want to do is rename a variable or function but oh no. "Xcode can only refactor C or Objective-C code". Yet they are plowing on with new features in other areas like the interface builder but completely ignoring the tools that make IDEs useful.

Is the search function useless?
I tried it in the official devRant app because I consider adding it to JoyRant.
But it never finds anything relevant for me.
Even if I give it an exact substring of a comment, it doesn’t find it.
It also doesn’t find users (which would be useful)
Does it only work for the text in a rant?
Do you find it useful?6 -
I am not a programmer, but I know a little bit of Python, C# and C++, but mostly basic syntax of latest two. Nevertheless it gives me higher ground, why?
I develop way od thinking which maker my life easier. I Havel intershop in Pharmacy and they print small papers with number which you show to get remaining drugs. Currently is number, 17592 which makes someone to type almost 40k numbers and erase also this amount. I use variable function in Libreoffice Writer and you have to type one number and it autonumber 64 (easily to expand but unnecessary) and save fucktone of time 😃 And this is why I thing that teaching programming is beneficial, because it develops mindset of resolving problems in easier way.
On the other hand in a few hours I wrote program for my girlfriend to draw randomly picture of herbal material (leaf, root, fruit etc) and ask for Latin name of this material, check if is correct and display necessary information. Programming was quick, most of time I prepare data for this software and this feels so fuxkibg awesome that I could use my knowledge to help my girlfriend and make something useful which makes me proud (code looks like blue waffle, but it works 😃). Fucking deadlines, but at least I could finish it 😃 -
I’m paying for GitHub Copilot and it is serving me well in about 40% of the cases. It is nice to not have to type entire utility methods. Sometimes it also try-catches things that I wouldn’t generally do with a new library that I haven’t used before. Pretty cool.
I also used the Cursor IDE, that isn’t very useful in general cases, but helped me read and understand a horrible piece of 200 line-function with extremely cryptic variable names. Sadly, my free quota there ended.
I hope GitHub Copilot Chat is better at explaining things.2 -
So at the HS I go to, there are 4~5 programmers (only 3 real "experienced" ones though including me).
So coming from JS & Python, I hate Java (especially for robotics) and prefer C++ (through some basic tutorials).
Programmer Nº2 is great at everything, loves Objective-C, Swift, Python, and to a certain extent Java.
Programmer Nº3 loves Python and used to do lots of C#, dislikes Java and appreciates Go (not much experience).
So naturally I get shit on (playfully) because of my JS background, because they don't understand many aspects of it. They hate the DOM manipulation (which is dislike too tbh), but especially OOP in JS, string/int manipulation, certain methods and HOISTING.
So, IDK if Java or C++ (super limited in them) have hoisting, but if you don't know what hoisting is, it means that you can define a variable, use it before assigning a value, and the code will still run. It also means that you can use a variable before defining it and assigning a value to it.
So in JS you can define a variable, assign no value to it, use it in a function for instance, and then assign a value after calling the function, like so:
var y;
function hi(x) {
console.log(y + " " + x);
y = "hi";
}
hi("bob");
output: undefined bob
And, as said before, you can use a variable before defining it - without causing any errors.
Since I can barely express myself, here is an example:
JS code:
function hi(x) {
console.log(y + " " + x);
var y = "hi";
}
hi("bob");
output: undefined bob
So my friends are like: WTF?? Doesn't that produce an Error of some sort?
- Well no kiddo, it might not make sense to you, and you can trash talk JS and its architecture all you want, but this somehow, sometimes IS useful.
No real point/punchline to this story, but it makes me laugh (internally), and since I really want to say it and my family is shit with computers, I posted it here.
I know many of you hate JS BTW, so I'm prepared to get trashed/downvoted back to the Earth's crust like a StackOverflow question.6 -
NodeJS and MongoDB. And tutorials.
Everywhere tutorials show simple example of console.log output of findOne. Good, that works... But when I try to extrapolate example to assign results to variable, it won't work. Inside that fetch anonymous function it works... But outside, simply undefined no matter what I try. Return doesn't return either...
Why it is so hard to make tutorials and examples that would be actually useful. I've spent hours with this already.
And on top of that it is really hard to find tutorials staying with minimum extra dependencies. Like most tutorials in this case throw mongoose in the soup. And I don't want that.
Sometimes makes me question why I try to learn these new things, when I have knowledge of other technologies that I could use faster and easier...3 -
Rustfmt doesn't support inline function calls with a block last argument unless the last argument is an array literal or lambda. Dedicated support for arrays is obviously intended for XML-like trees where a factory takes a number of arguments and then a list of children, and the use cases for block last lambda argument don't need explanation, but what I don't get is how did no one catch on that this is a useful pattern that should perhaps be generalized? Why can't I produce the same behaviour for a function call in the last position.3

You know
When I first saw etherum talking about am distributed state machine i thought wow. Not very practical but NEAT. I envisioned being able to make a byte code that could be stored in transactions and run by individual clients in an async function and each step of the resulting execution and the values of managed ram would be stored at intervals so other clients could take over and execute a few more statements and compare what should always be expected results that are identical
A grand incredibly inefficient system however really neato from the theoretical computer nerd standpoint !
Boy was I disappointed lol all it is a basic contracts language but yet they state it could be like a word computer ! How ? I thought maybe if you had enough nodes participating maybe you could store registers and the like in transaction values ? Wouldn’t that be the way ?
Seems like as a word computer they’re stuck somewhere between very simplistic js and something prior to amptron in usability yet they advertised as a world computer
Am i missing something ? I mean you could create something that would translate higher level code into smal numeric statements and then send it additions values but what would it be useful for and how would you actually. Store anything ?
