Started being a Teaching Assistant for Intro to Programming at the uni I study at a while ago and, although it's not entirely my piece of cake, here are some "highlights":
* students were asked to use functions, so someone was ingenious (laughed my ass off for this one):
def all_lines(input):
all_lines =input
return all_lines
* "you need to use functions" part 2
*moves the whole code from main to a function*
* for Math-related coding assignments, someone was always reading the input as a string and parsing it, instead of reading it as numbers, and was incredibly surprised that he can do the latter "I always thought you can't read numbers! Technology has gone so far!"
* for an assignment requiring a class with 3 private variables, someone actually declared each variable needed as a vector and was handling all these 3 vectors as 3D matrices
* because the lecturer specified that the length of the program does not matter, as long as it does its job and is well-written, someone wrote a 100-lines program on one single line
* someone was spamming me with emails to tell me that the grade I gave them was unfair (on the reason that it was directly crashing when run), because it was running on their machine (they included pictures), but was not running on mine, because "my Python version was expired". They sent at least 20 emails in less than 2h
* "But if it works, why do I still have to make it look better and more understandable?"
* "can't we assume the input is always going to be correct? Who'd want to type in garbage?"
* *writes 10 if-statements that could be basically replaced by one for-loop*
"okay, here, you can use a for-loop"
*writes the for loop, includes all the if-statements from before, one for each of the 10 values the for-loop variable gets*
* this picture
N.B.: depending on how many others I remember, I may include them in the comments afterwards19 -
Line numbers should be on by default on all editors for fucks sake. Why the hell it is the other way around??11

curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line
tldr
do curl cht.sh/go/execute+external+program to see how to execute external program in go
And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?
I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.
Nowadays you probably know, how to check the weather from the command line, but if not:
curl wttr.in
or
curl wttr.in/Paris
(curl wetter in Paris if you want to know the weather in Paris)
After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):
curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text
And now last but not least, the gem in this collection: cheat.sh.
The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.
With cheat.sh you don't need to install anything, just do:
curl cheat.sh/tar (or whatever)
you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).
But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.
Now you can simply do:
curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read
or even
curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件
and get your question answered
(cht.sh is an alias for cheat.sh).
And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.
One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.
The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.
The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh
What do you think about this service?
What do you think about this approach?
Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?26 -
Interviewed a dev for a junior role earlier this week...my first question:
const numbers = [0.1, 0.2, 0.3];
let sum = 0;
for (i = 0; i < numbers.length; ++i) {
setTimeout(() => {
sum += numbers[i];
}, 0);
}
// Refactor the preceding code so that the following returns true.
console.log(sum === 0.6);

He had no idea where to even start, so I asked him to walk through the code with me line by line, he couldn't get past line 1 - literally didn't know what an array was... I walked through the code with him and he just started to look more and more lost.
I didn't even bother with the rest of my questions on OOP, FP, etc...
Am I really expecting too much of somebody that claims to have 2 years practical experience in JavaScript, jQuery, Angular, and PHP?
Do you think this is a problem a junior dev should be able to solve...even if it takes some hand-holding?57 -
Heck yes!
I implement a stack trace in my embedded systems!
Whenever a device crashes, it makes a stack dump in an unused part of ram.
After it has rebooted and is connected to the server again, it uploads the stack dump.
The server then opens the correct firmware elf file, walks the stack and associates the debug info from the elf.
The result? A beautiful stack trace with file names, function names and line numbers.
No more guessing where random crashes come from.12 -
Large comment block at the top of the file, commenting explicit line numbers, as in: "line 365: copy to a new image".
Only everytime the comment block grew, the line numbers got more and more off. -_-4 -
Whoever implemented the data import in Numbers on Mac needs to be lined up against a wall and shot with needles until they wish they were dead.
Why on all of gods unholy green and shitty earth would i want data i import (EVEN IN CSV FOR FUCK SAKE) to be delimited by an arbitrary text width? WHAT THE ACTUAL FUCK
WHY WHY why would I EVER want to delimit my carefully structured data by fucking text width instead of new line or comma? AAAAARRRHHH
And what fucking big brain genius made this the DEFAULT SETTING for imported text AND CSV FILES. IT STANDS FOR COMMA SEPARATED FILE YOU FUCK BOI MAYBE JUST MAYBE I WANT IT SEPARATED BY FUCKING COMMMMMMMAAAAASSSSSS9 -
WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.
The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.
Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.
My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.
And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.
And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.
And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.
And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.
I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.7 -
I had a huge epiphany on Friday... not all developers enjoy coding.
Discovered when they brought down 2 of our environments, well told them what was wrong with the changes in their code that caused the environments to break, gave them links directly to the file in the gitlab repo that needed to be updated, and...
They fucking went home. The change would’ve taken all of about 30-45 seconds to update and they fucking left.
This person’s team lead come storming in pissed off because her manager is furious about 2 environments going down and preventing everyone else from being able to deploy their changes.
We provide the exact same details to the team lead about what needs to be changed, and advise that her team member took off....
30 mins later, her manager is storming up to us (devops/sre) livid as hell.
Explain the situation for a third time... manager is like, why can’t you guys fix it?
Look here you dense motherfuckers, we can fix the code. We can be the plumbers that clean up your shit. But what value do you gain as a developer if you don’t understand how the systems work and you keep pushing shit in?
Made the changes, fixed the environments, done right? Wrong.
The original developer made more changes not knowing what would happen and thoroughly fucked the environments again.
This dumb-fucking dumpster fire of a dude then sends us a slack message. “It’s down again, can you fix it?”
Our manager steps in and tells us to send him a link to the logs and have him fix it himself!
Thank goodness we have a badass manager.
Send logs, send repo file links (again), and send line numbers in the logs to try and help just a bit more. Dude goes almost the whole day without fixing it, environments are down, other devs are pissed, we throw this dude to the wolves. His manager starts to head over and was about to talk with my team lead when our manager steps out of his office and tells him the in’s and out’s of the situation and that our job isn’t to play log parser/error fixer for the developers. This dude that’s breaking the environments needs to be the one to fix the issue and his team lead should be aware of the problems and should have been able to correct his errors before it ever came to us.
The amount of hand-holding we do is ridiculous.
(Disclaimer, this one guy making some mistakes doesn’t sound too bad, but this is actually a common occurrence for like 40% of all of our developers)
We literally have interns still in college running circles around some of our full time devs. I know I’m not a developer, but for anyone that’s new-ish to developing, when you see shit like that please don’t lose hope. Those ass-hats got into programming purely for a paycheck, not because of passion.
Stick with it and your greatness will know no bounds 👍
As for you craptastic dipstick lickers, FUCK YOU!!! Go back to school and learn how to give a damn.4 -

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 -
A dev team has been spending the past couple of weeks working on a 'generic rule engine' to validate a marketing process. The “Buy 5, get 10% off” kind of promotions.
The UI has all the great bits, drop-downs, various data lookups, etc etc..
What the dev is storing the database is the actual string representation FieldA=“Buy 5, get 10% off” that is “built” from the UI.
Might be OK, but now they want to apply that string to an actual order. Extract ‘5’, the word ‘Buy’ to apply to the purchase quantity rule, ‘10%’ and the word ‘off’ to subtract from the total.
Dev asked me:
Dev: “How can I use reflection to parse the string and determine what are integers, decimals, and percents?”
Me: “That sounds complicated. Why would you do that?”
Dev: “It’s only a string. Parsing it was easy. First we need to know how to extract numbers and be able to compare them.”
Me: “I’ve seen the data structures, wouldn’t it be easier to serialize the objects to JSON and store the string in the database? When you deserialize, you won’t have to parse or do any kind of reflection. You should try to keep the rule behavior as simple as possible. Developing your own tokenizer that relies on reflection and hoping the UI doesn’t change isn’t going to be reliable.”
Dev: “Tokens!...yea…tokens…that’s what we want. I’ll come up with a tokenizing algorithm that can utilize recursion and reflection to extract all the comparable data structures.”
Me: “Wow…uh…no, don’t do that. The UI already has to map the data, just make it easy on yourself and serialize that object. It’s like one line of code to serialize and deserialize.”
Dev: “I don’t know…sounds like magic. Using tokens seems like the more straightforward O-O approach. Thanks anyway.”
I probably getting too old to keep up with these kids, I have no idea what the frack he was talking about. Not sure if they are too smart or I’m too stupid/lazy. Either way, I keeping my name as far away from that project as possible.4 -
Where I work we develop drivers and command-line software for embedded systems. The contracts we have with our customers tend to be in the £100k-£500k range and are usually completed in 6 - 9 months; our team is made up of 20 developers. You would think that it would be worthwhile investing in the department. But no, instead we have to deal with >10 year old build servers on their last legs; limited numbers of development boards with wires soldered on so that we can keep up with new board revisions; no room for R&D into new products; and to top it all off, not one of the executives has a laptop on par with the placement students in the next department. It's like the company is trying to kill the department, we've seen our staffing dwindle with no new graduate (or higher) positions being made available in the last 3 years while we've lost at least 5 people to other places. I just don't get it!2
-
Woohoo!!! I made it to 1000++s :) Now I feel less newbie-like around here :)
So... I don't want to shit-post, so in gratitude to all you guys for this awesome community you've built, specially @trogus and @dfox, I'll post here a list of my ideas/projects for the future, so you guys can have something to talk about or at least laugh at.
Here we go!
Current Project: Ensayador.
It's a webapp that intends to ease and help students write essays. I'm making it with history students in mind, but it should also help in other discipline's essay production. It will store the thesis, arguments, keywords and bibliography so students can create a guideline before the moment of writting. It will also let students catalogue their reads with the same fields they'd use for an essay: that is thesis, arguments, keywords and bibliography, for their further use in other essays. The bibliography field will consist on foreign keys to reads catalogued. The idea is to build upon the models natural/logical relations.
Apps: All the apps that will come next could be integrated in just one big app that I would call "ChatPo" ("Po" is a contextual word we use in my country when we end sentences, I think it derived from "Pues"). But I guess it's better to think about them as different apps, just so I don't find myself lost in a neverending side-project.
A subchat(similar to a subreddit)-based chat app:
An app where people can join/create sub-chats where they can talk about things they are interested in. In my country, this is normally done by facebook groups making a whatsapp group and posting the link in the group, but I think that an integrated app would let people find/create/join groups more easily. I'm not sure if this should work with nicknames or real names and phone numbers, but let's save that for the future.
A slack clone:
Yes, you read it right. I want to make a slack clone. You see, in my country, enterprise communications are shitty as hell: everything consists in emails and informal whatsapp groups. Slack solves all these problems, but nobody even knows what it is over here. I think a more localized solution would be perfect to fill this void, and it would be cool to make it myself (with a team of friends of course), and hopefully profit out of it.
A labour chat-app marketplace:
This is a big hybrid I'd like to make based on the premise of contracting services on a reliable manner and paying through the app. "Are you in need of a plumber, but don't know where to find a reliable one? Maybe you want a new look on your wall, but don't want to paint it yourself? Don't worry, we got you covered. In <Insert app name> you can find a professional perfect to suit your needs. Payment? It's just a tap away!". I guess you get the idea. I think wechat made something like this, I wonder how it worked out.
* Why so many chat apps? Well... I want to learn Erlang, it is something close to mythical to me, and it's perfect for the backend of a comms app. So I want to learn it and put it in practice in any of these ideas.*
Videogames:
Flat-land arena: A top down arena game based on the book "flat land". Different symmetrical shapes will fight on a 2d plane of existence, having different rotating and moving speeds, and attack mechanics. For example, the triangle could have a "lance" on the front, making it agressive but leaving the rest defenseless. The field of view will be small, but there'll be a 2d POV all around the screen, which will consist on a line that fills with the colors of surrounding objects, scaling from dark colors to lighter colors to give a sense of distance.
This read could help understand the concept better:
http://eldritchpress.org/eaa/...
A 2D darksouls-like class based adventure: I've thought very little about this, but it's a project I'm considering to build with my brothers. I hope we can make it.
Imposible/distant future projects:
History-reading AI: History is best teached when you start from a linguistic approach. That is, you first teach both the disciplinar vocabulary and the propper keywords, and from that you build on causality's logic. It would be cool to make an AI recognize keywords and disciplinary vocabulary to make sense of historical texts and maybe reformat them into another text/platform/database. (this is very close to the next idea)
Extensive Historical DB: A database containing the most historical phenomena posible, which is crazy, I know. It would be a neverending iterative software in which, through historical documents, it would store historical process, events, dates, figures, etc. All this would then be presented in a webapp in which you could query historical data and it would return it in a wikipedia like manner, but much more concize and prioritized, with links to documents about the data requested. This could be automated to an extent by History-reading AI.
I'm out of characters, but this was fun. Plus, I don't want this to be any more cringy than it already is.12 -
Starting my new bot experience together with Discord.
Discord is kinda easier than LINE. You had to create facebook accounts or fake lots of telephone numbers to be able to verify your bot account. They also kept changing the endpoints to avoid people using their bots.
Discord is the opposite. Discord loves bots. And that's why I start feeling love towards Discord.8 -
Was just thinking of building a command line tool's to ease development of some of my games assets (Just packing them all together) and seeing as I want to use gamemaker studio 2 thought that my obsession with JSON would be perfect for use with it's ds_map functions so lets start understanding the backend of these functions to tie them with my CL tool...
*See's ds_map_secure_save*
Oh this might be helpful, easily save a data structure with decent encryption...
*Looks at saved output and starts noticing some patterns*
Hmm, this looks kinda familiar... Hmmm using UTF-8, always ends with =, seems to always have 8 random numbers at the start.. almost like padding... Wait... this is just base64!
Now yoyogames, I understand encryption can be hard but calling base64 'secure' is like me flopping my knob on the table and calling it a subtle flirt...6 -
LPT: NEVER accept a freelance job without looking at the project's source first
Client: I have a project made by a company that is now abandoning it, I want you to fix some bugs
Me: Okay, can you:
1) Give me a build to test the current state of the game
2) Tell me what the bugs are
3) Show me the source
4) Tell me your budget
Client: *sends a list of 10 bugs* Here's the APK and to give you the project I'll need you to sign an NDA
Me: Sure...
*tests build*
*sees at least 20 bugs*
*still downloading source*
*bugs look quite easy to fix should be done under an hour*
Me: Okay, so, I can fix each bug for $10 and I can do 2 today
Client: Okay can you fix 8 bugs today for $40??
*sigh*
Me: No I cannot.
Client: okay then 2 today for $20 is fine, I want a refund if you can't fix them today
*sigh*
Me: Look dude, this isn't the first time I am doing this, aight? I'll fix the bugs today you can pay me after check they are done, savvy?
Client: okay
*source is downloaded*
*literal apes wrote the scripts, commented out code EVERYWHERE
Debug logs after every line printing every frame causing FPS drops, empty objects in the scene
multiple unused UI objects
everything is spaghetti*
*give up, after 2 hours of hell*
*tfw averted an order cancellation by not taking the order and telling client that they can pay me after I am done*
Attached is an image of a level object pool
It's an array with each element representing a level.
The numbers and "Final" are ids for objects in an object pool
The whole string is .Split(',') into an array (RIP MEMORY BTW) and then a loop goes through each element in the split array and instantiates the object from an object pool5 -
Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

They actually did it...
Cheezus Crust, they actually "generated" 3 HTML selects to let a user chose a Date.
(nvm the line numbers, it ends at 3000)
They didn't even bother to generate the fucking arrays lol15 -
So... did I mention I sometimes hate banks?
But I'll start at the beginning.
In the beginning, the big bang created the universe and evolution created humans, penguins, polar bea... oh well, fuck it, a couple million years fast forward...
Your trusted, local flightless bird walks into a bank to open an account. This, on its own, was a mistake, but opening an online bank account as a minor (which I was before I turned 18, because that was how things worked) was not that easy at the time.
So, yours truly of course signs a contract, binding me to follow the BSI Grundschutz (A basic security standard in Germany, it's not a law, but part of some contracts. It contains basic security advice like "don't run unknown software, install antivirus/firewall, use strong passwords", so it's just a basic prototype for a security policy).
The copy provided with my contract states a minimum password length of 8 (somewhat reasonable if you don't limit yourself to alphanumeric, include the entire UTF 8 standard and so on).
The bank's online banking password length is limited to 5 characters. So... fuck the contract, huh?
Calling support, they claimed that it is a "technical neccessity" (I never state my job when calling a support line. The more skilled people on the other hand notice it sooner or later, the others - why bother telling them) and that it is "stored encrypted". Why they use a nonstandard way of storing and encrypting it and making it that easy to brute-force it... no idea.
However, after three login attempts, the account is blocked, so a brute force attack turns into a DOS attack.
And since the only way to unblock it is to physically appear in a branch, you just would need to hit a couple thousand accounts in a neighbourhood (not a lot if you use bots and know a thing or two about the syntax of IBAN numbers) and fill up all the branches with lots of potential hostages for your planned heist or terrorist attack. Quite useful.
So, after getting nowhere with the support - After suggesting to change my username to something cryptic and insisting that their homegrown, 2FA would prevent attacks. Unless someone would login (which worked without 2FA because the 2FA only is used when moving money), report the card missing, request a new one to a different address and log in with that. Which, you know, is quite likely to happen and be blamed on the customer.
So... I went to cancel my account there - seeing as I could not fulfill my contract as a customer. I've signed to use a minimum password length of 8. I can only use a password length of 5.
Contract void. Sometimes, I love dealing with idiots.
And these people are in charge of billions of money, stock and assets. I think I'll move to... idk, Antarctica?4 -
Cracking old recovery CDs for the 9x/2000/XP era shines some light into how companies operated and when concepts came to be in that time:
Packard Bell: An EXE checks that you're running on a Packard Bell machine and reboots if it's not. How do we bypass it? Easy: just fucking delete it. The files to reinstall Windows from scratch come from...
...
C:?
Yup. Turns out Packard Bell was doing the recovery partition thing all the way back to the 9x era, maybe even further. Files aren't even on the restore disc so if your partition table got fucked (pretty common because malware and disk corruption) you were totally fucked and needed to repurchase Windows. (My dad, at the time, only charged at-cost OEM prices for a replacement retail copy. He knew it was dumb so he never sold PB machines.)
Compaq:
Computer check? Nope, remove one line from a BATCH file and it's gone.
Six archives, named "WINA.ZIP" through "WINF.ZIP" (plus one or two extras for OEM software) hold Windows. Problematic? Well... only because they never put the password anywhere so the installer can't install them. (Some interesting on-disc technician-only utils, though!)
Dell:
If not a Dell machine, lock up. Cause? CONFIG.SYS driver masquerading as OAK (the common CD driver) doing the check, then chainloading the real OAK driver. Simple fix: replace the fake driver with the real one.
Issues?
Would I mention this one if there weren't?
Disc is mounted on N:. Subdirectories work, but doing anything in them (a DIR, trying to execute something, trying to view shit in EDIT.COM) kicked you back to the disc root.
Installer couldn't find machine manifest in the MAP folder (it wanted your PC's serial before it'd let you install, to make sure you have the correct recovery disc) so it asked for 12-digit alphanumeric serial. The defined serials in the manifest were something like "02884902-01" or similar (8-2, all numbers) and it couldn't read the file so it couldn't show the right format, nor check for the right type.
Bypassing that issue, trying to do the ACTUAL install process caused nothing to happen... as all BATCHes for install think the CD should be on X:.
Welp.
well that was fun. Now to test on-real-PC behavior, as VBOX and VMWare both don't like the special hardware shit it tries to use. (Why does a textmode GUI need GPU acceleration, COMPAQ?????)4 -
This whole corporate numbers game is killing me. I know I'm getting paid to do what I'm asked, I know. But the metrics are so one dimensional
You fixed the data of 20 tests? Doesn't count because you didn't code
You implemented a function to reduce recurrent failures in the future? Doesn't count because those already pass with time consuming workarounds
You spent half a day communicating and coordinating across teams to fix an issue? That's 1 test, this other person changed 1 line in 5 files, you're 4 tests behind4 -
Jest addin for vscode:
The Good
- I love how it's running all the time testing my code
The Bad
- Doesn't show line numbers where the problems are (may be a babel/promises issue perhaps)
- Doesnt have coloured text (normal jest runner does)
- I can't get debugging working (I'm sure I will eventually)

Doing a full rewrite from some DIY spaghetti framework: when it can't find a search query it returns "false" with the status code 200, the same php file responsible for querying an external api is put into all sorts of named folders, so e.g. a user that is in the results page X can continue searching on the same URL, instead of doing proper url rewrites or ajax calls to the one in the root directory, html is thrown into every other php line, a DIY sort function for a numbers array that fails to sort 0 before 1 and that all is just a 10 minute review, can't wait to see the rest.2

Everyone and their dog is making a game, so why can't I?
1. open world (check)
2. taking inspiration from metro and fallout (check)
3. on a map roughly the size of the u.s. (check)
So I thought what I'd do is pretend to be one of those deaf mutes. While also pretending to be a programmer. Sometimes you make believe
so hard that it comes true apparently.
For the main map I thought I'd automate laying down the base map before hand tweaking it. It's been a bit of a slog. Roughly 1 pixel per mile. (okay, 1973 by 1067). The u.s. is 3.1 million miles, this would work out to 2.1 million miles instead. Eh.
Wrote the script to filter out all the ocean pixels, based on the elevation map, and output the difference. Still had to edit around the shoreline but it sped things up a lot. Just attached the elevation map, because the actual one is an ugly cluster of death magenta to represent the ocean.
Consequence of filtering is, the shoreline is messy and not entirely representative of the u.s.
The preprocessing step also added a lot of in-land 'lakes' that don't exist in some areas, like death valley. Already expected that.
But the plus side is I now have map layers for both elevation and ecology biomes. Aligning them close enough so that the heightmap wasn't displaced, and didn't cut off the shoreline in the ecology layer (at export), was a royal pain, and as super finicky. But thankfully thats done.
Next step is to go through the ecology map, copy each key color, and write down the biome id, courtesy of the 2017 ecoregions project.
From there, I write down the primary landscape features (water, plants, trees, terrain roughness, etc), anything easy to convey.
Main thing I'm interested in is tree types, because those, as tiles, convey a lot more information about the hex terrain than anything else.
Once the biomes are marked, and the tree types are written, the next step is to assign a tile to each tree type, and each density level of mountains (flat, hills, mountains, snowcapped peaks, etc).
The reference ids, colors, and numbers on the map will simplify the process.
After that, I'll write an exporter with python, and dump to csv or another format.
Next steps are laying out the instances in the level editor, that'll act as the tiles in question.
Theres a few naive approaches:
Spawn all the relevant instances at startup, and load the corresponding tiles.
Or setup chunks of instances, enough to cover the camera, and a buffer surrounding the camera. As the camera moves, reconfigure the instances to match the streamed in tile data.
Instances here make sense, because if theres any simulation going on (and I'd like there to be), they can detect in event code, when they are in the invisible buffer around the camera but not yet visible, and be activated by the camera, or deactive themselves after leaving the camera and buffer's area.
The alternative is to let a global controller stream the data in, as a series of tile IDs, corresponding to the various tile sprites, and code global interaction like tile picking into a single event, which seems unwieldy and not at all manageable. I can see it turning into a giant switch case already.
So instances it is.
Actually, if I do 16^2 pixel chunks, it only works out to 124x68 chunks in all. A few thousand, mostly inactive chunks is pretty trivial, and simplifies spawning and serializing/deserializing.
All of this doesn't account for
* putting lakes back in that aren't present
* lots of islands and parts of shores that would typically have bays and parts that jut out, need reworked.
* great lakes need refinement and corrections
* elevation key map too blocky. Need a higher resolution one while reducing color count
This can be solved by introducing some noise into the elevations, varying say, within one standard div.
* mountains will still require refinement to individual state geography. Thats for later on
* shoreline is too smooth, and needs to be less straight-line and less blocky. less corners.
* rivers need added, not just large ones but smaller ones too
* available tree assets need to be matched, as best and fully as possible, to types of trees represented in biome data, so that even if I don't have an exact match, I can still place *something* thats native or looks close enough to what you would expect in a given biome.
Ponderosa pines vs white pines for example.
This also doesn't account for 1. major and minor roads, 2. artificial and natural attractions, 3. other major features people in any given state are familiar with. 4. named places, 5. infrastructure, 6. cities and buildings and towns.
Also I'm pretty sure I cut off part of florida.
Woops, sorry everglades.
Guess I'll just make it a death-zone from nuclear fallout.
Take that gators!5 -
(Dev)Life in the past 12 hours
Oh boy have the last 12 hours been a roller coaster ride for me. Noob me decided to "compile" AoSP for my device to get a taste of how custom ROMs are built from source. Overall it was fun but the errors were a very good excercise for googling, SO. Couple stuff I learnt ( possibly useful for anyone who comes here )
* The shebang line ( #!/usr/bin/env python ) on my system translated to Python 3.7 environment instead of the expected Python 2.7. Best solution I think to avoid confusion is to create a python 2.7 environment and source it.
* Get your trees right. A jar file called WfdCommon.jar ( apparently known as wifi-display common ) was the cause of several hours of hunting the fault. My vendor tree somehow didn't have this file so dex2oat was borking out like mad. I'm still amazed how I figured this one out almost by myself. ( Basically I had to check every file included in the boot class path, and find the odd one )
* I wasted a lot of time in finding the right files to change version numbers and all. Maybe I didn't search XDA properly for a guide ?
Overall it was a fun experience. Also if anyone's experienced in this area could you share resources to learn more about custom ROM development? Specifically on the tweaking part where you mix features from different ROMs to make a great ROM ( like AoSP extended or Pixel Experience ). All I could find were on the zips and not on sources.7 -
Working with atlassian products....
Possibility 1
You can either use exactly this one way and only with these specific instructions ...
Which will certainly not work for the project you have.
Possibility 2
There is an feature request which gets ignored for years, someone made a plugin...
But plugin was removed as inactive. :-)
Possibility 3
Atlassian provided in their endless graciousness a plugin.
After hours of deciphering Kotlin / Java code as the documentation is either useless or lacking details...
You did it. You got the REST shit working.
Well.
You just needed a script which wraps the underlying command, parses the commands well defined format like XML with specification.... To a completely gobbled up JSON, that looks like undecipherable shit.
I really hate Atlassian.

A really unnecessary and seldomly used future as it seems.
And yeah... The JSON contains a coverage element which contains a semicolon separated key value store, value being a comma separated list of line numbers....4 -
WTF IS WRONG WITH ASSEMBLY LANGUAGE?!
I was just modifying an existing program for adding a sequence of numbers from the data section and through console input. I studied the code and started modifying it one step at a time. I needed to modify it into a multiplication program. So I started by changing the ADD functions, replaced the result and buffer registers with bigger size and thought I completed it. WELL GUESS WHAT?

300 global variables.. THREE HUNDRED FUCKING GLOBAL VARIABLES?
Are you for real?
Now let me check the line numbers again..
hmm.. line 97 to .. yep line 410, just a few new lines to seperate some of them or.. group? Idk, I've given up on trying to understand those.
Now you may ask "But ThatPerlDeb, where did you see this and what was the intention?"
Low and behold, take a chair and I may explain this to you.
First of all: Fuck the dev that wrote this!
Second: Fuck all the devs that kept up with this practice or whatever you want to fucking call this!
Now, the application is our POS system that our customers can use for a monthly fee (That this piece of garbage even requires payment is disgusting) but anyway..
The global variables sometimes are declared for labels, sometimes for some frames, sometimes just for random values to be there.
We're using Perl for the POS system and Perl ain't the best at OOP, so in the dev's defense I can understand why you'd use a few global variables, but not fucking 300!! FUCK OFF WITH THIS BULLSHIT!!
So now I'm going through this torture slowly but surely deleting globals and putting them into some sort of scope and always MANUALLY test if something broke. Again, this company sucks ass and there's nothing that could even be considered a "unit test" or something like that, so fuck that, too.
After two hours I've brought down the count of global variables to about 260, so there's progress being made..
But then, there comes more!
"But how???" you may ask, and you're right, I've asked that myself.
Now to resolve the global stuff in each file some of the initial globals are used, we got about 20-30 files which do different stuff, all fair and square, at least there was an attempt at seperating functions but god this mess is so fucking fucked up. So in order to "safely" delete a global variable I have to check if any of the variables are used in another file, and if so, in which scope and how they are used.
Spaghetti would be a compliment for this fucking disgusting piece of utter bullshit.
Let alone the code quality of this "code"
Indendation? Dafuq is dat?
Scope? Nah, we got everything global anyway
Function size? Well, some are 5 lines, some are 900 lines, who cares anyways, right?
I'm so fucking glad once I leave this shithole, for real.6 -
So this is what a test looks like here in my school...
I really like my teacher but his test are... uhh... fucking awful.
I mean the code isn't even indented ffs! Like wtf?!? How should one be able to read this bullshit?
The questions are shitty too.
Also please add line numbers so it is easier to describe how things work in the code.
AND USE FUCKING A4 PAPERS FFS!!!

My LinkedIn is usually pretty quiet. Recently I've received quite a few messages from recruiters. Some of them put numbers in and I look at them, well, the market looks hot.
I like where I am but doesn't hurt to have a look around eh? So I went through some interviews and shit. No preps, not trying to please anyone, being completely honest. And out of the 3 I tried, 1 got to the final round.
Before the final round, the recruiter kept harassing me (it's their job really) about what my "bottom line" is. She said they really liked me but I'm not up to their expectation as a senior role. So they want to proceed with a non-senior role, then climb my ladder up. I told her, I don't give a shit about the title. The she said for that, the salary will be "adjusted" (reads reduced). I told her, look, I said I wouldn't bother if the offer is anything less than X amount of money. Then she said but this company would offer 10% bonus, which will add up , mind you, "close to" X. She said she wanted to know so we don't waste the director's time (as the final round is to meet the bloody director).
I said, if I need to disclose my bottom line before going to this, which is pretty much my negotiation, then let's call it off. No point wasting my time either.
The next day I received the last call from her. They fucked right off.
I know everyone here already knows. But let me experience be another example of how a plague recruiters is. I don't have any experience like this before but this is probably a fucking lowball case too.3 -

Oh BASIC night, the LEDs are brightly glinting;
It is the night of the dear GOSUB’s birth!
Long lay the world in sin and error printing,
Till you appeared and the RAM felt its worth.
Shiver of fear, line numbers do inspire,
For yonder breaks a mostly harmless GOTO.
Fall on your bits, O hear the Visual voices!
O BASIC divine, O BASIC where GOTO was born!
O BASIC, O Holy BASIC, O BASIC, you’re mine!
Some want to say, “GOTO is harmful always,”
But what of them, in their post-modern world.
We PRINT the truth, in the line-numbered goodness,
But Dijkstra appeared, and the faith, it was lost.
A thrill of hope, when .NET BASIC announces,
But Visual BASIC, what kind of thing are you?
Fall on your GUI, O see the old line numbers!
Behold BASICA, O BASIC when DOS was born!
O numbers, O lines, spaghetti divine!

When we subtract some number m from another number n, we are essentially creating a relationship between n and m such that whatever the difference is, can be treated as a 'local identity' (relative value of '1') for n, and the base then becomes '(base n/(n-m))%1' (the floating point component).
for example, take any number, say 512
697/(697-512)
3.7675675675675677
here, 697 is a partial multiple of our new value of '1' whose actual value is the difference (697-512) 185 in base 10. proper multiples on this example number line, based on natural numbers, would be
185*1,
185*2
185*3, etc
The translation factor between these number lines becomes
0.7675675675675677
multiplying any base 10 number by this, puts it on the 1:185 integer line.
Once on a number line other than 1:10, you must multiply by the multiplicative identity of the new number line (185 in the case of 1:185), to get integers on the 1:10 integer line back out.
185*0.7675675675675677 for example gives us
185*0.7675675675675677
142.000000000000
This value, pulled from our example, would be 'zero' on the line.
185 becomes the 'multiplicative' identity of the 1:185 line. And 142 becomes the additive identity.
Incidentally the proof of this is trivial to see just by example. if 185 is the multiplicative identity of 697-512, and and 142 is the additive identity of number line 1:185
then any number '1', or k=some integer, (185*(k+0.7675675675675677))%185
should equal 142.
because on the 1:10 number line, any number n%1 == 0
We can start to think of the difference of any two integers n, as the multiplicative identity of a new number line, and the floating point component of quotient of any number n to the difference of any number n-m, as the additive identity.
let n =697
let m = 185
n-m == '1' (for the 1:185 line)
(n-m) * ((n/(n-m))%1) == '0'
As we can see just like on the integer number line, n%1 == 0
or in the case of 1:185, it equals 142, our additive identity.
And now, the purpose of this long convoluted post: all so I could bait people into reading a rant on division by zero.30 -
You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)

Maybe I'm severely misunderstanding set theory. Hear me out though.
Let f equal the set of all fibonacci numbers, and p equal the set of all primes.
If the density of primes is a function of the number of *multiples* of all primes under n,
then the *number of primes* or density should shrink as n increases, at an ever increasing rate
greater than the density of the number of fibonacci numbers below n.
That means as n grows, the relative density of f to p should grow as well.
At sufficiently large n, the density of p is zero (prime number theorem), not just absolutely, but relative to f as well. The density of f is therefore an upper limit of the density of p.
And the density of p given some sufficiently large n, is therefore also a lower limit on the density of f.
And that therefore the density of p must also be the upper limit on the density of the subset of primes that are Fibonacci numbers.
WHICH MEANS at sufficiently large values of n, there are either NO Fibonacci primes (the functions diverge), and therefore the set of Fibonacci primes is *finite*, OR the density of primes given n in the prime number theorem
*never* truly reaches zero, meaning the primes are in fact infinite.
Proving the Fibonacci primes are infinite, therefore would prove that the prime number line ends (fat chance). While proving the primes are infinite, proves the Fibonacci primes are finite in quantity.
And because the number of primes has been proven time and again to be infinite, as far back as 300BC,the Fibonacci primes MUST be finite.
QED.

Today I could finally spend some time reviewing the merge requests an intern made (and I occasionally helped).
My god, I want to put it this months amount of work an, put it in a trash, burn it and rewrite it before the fire is gone.
5 small and unrelated issues. The intern used branches with the correct naming scheme, but IT'S A FUCKING STRAIGHT LINE BUILDING ON TOP OF EACHOTHER.
Oh ans also they took the liberty to update the dependencies and the language versions used. There was no issue regarding this. It's the first branch in the line and it was called "update_<dependency>" where they just upped the version numbers of everything and then COMMENT OUT all mentions of <dependency> so that it compiles at the very least.
Now today I spend most of my time reviewing the code by fixing that mess. Thanks to updates I had to update the CI and replace some libraries that are now incompatible. Tomorrow I can finally inspect the shit itself.

A few years ago I had a client that wanted a site transfered to their servers before it was complete. They then took over, making changes to their files. Then they would ask me to change some js and css that they couldn't figure out. Since neither them or I were using source control, I had to add my changes to a text doc and send to them with the file names and line numbers. What a pain.

I once tried to create a client for the fonds bank of Frankfurt. But I didn't expect their JSON API to be designed by a trainee.
Look at the API.
Stringified numbers, decimal commas (Germany), separator dots for thousands, and even one breaks as if it came from a pjp script where they just put an if condition in each line.
I documented the API and tried to create a Jax rs client, but stopped completing it. Not useable atm. Just look at what I spoofed.

In an IT management class, the professor wanted us to estimate the operation costs for a small IT company, breaking them down by service offered. I remember creating a markdown file, multiple times executing the line `echo $RANDOM >> estimations.md`. We rounded the numbers slightly, pimped the document a bit and submitted a nice PDF. When we had to present our work, the professor asked us how we had proceeded to calculate those results. We told him a story about an Excel file we worked on, but did not submit, because we thought he'd be interested in the end result and not care about those details. He asked us to submit that Excel calculation, because he wanted to comprehend our method. So we got together, created an Excel sheet, copied our "estimations" into column C and called it "service cost". For column B, we used the same "cost per man hour" value (scientifically estimated using the RAND() function) for every row. Finally, we divided the "service cost" by the "cost per man hour" for every row, put the result in column A and called it "effort (in man hours)". The professor, being able to "reproduce" our estimation, accepted our solution.2

This is gonna be a long post, and inevitably DR will mutilate my line breaks, so bear with me.
Also I cut out a bunch because the length was overlimit, so I'll post the second half later.
I'm annoyed because it appears the current stablediffusion trend has thrown the baby out with the bath water. I'll explain that in a moment.
As you all know I like to make extraordinary claims with little proof, sometimes
for shits and giggles, and sometimes because I'm just delusional apparently.
One of my legit 'claims to fame' is, on the theoretical level, I predicted
most of the developments in AI over the last 10+ years, down to key insights.
I've never had the math background for it, but I understood the ideas I
was working with at a conceptual level. Part of this flowed from powering
through literal (god I hate that word) hundreds of research papers a year, because I'm an obsessive like that. And I had to power through them, because
a lot of the technical low-level details were beyond my reach, but architecturally
I started to see a lot of patterns, and begin to grasp the general thrust
of where research and development *needed* to go.
In any case, I'm looking at stablediffusion and what occurs to me is that we've almost entirely thrown out GANs. As some or most of you may know, a GAN is
where networks compete, one to generate outputs that look real, another
to discern which is real, and by the process of competition, improve the ability
to generate a convincing fake, and to discern one. Imagine a self-sharpening knife and you get the idea.
Well, when we went to the diffusion method, upscaling noise (essentially a form of controlled pareidolia using autoencoders over seq2seq models) we threw out
GANs.
We also threw out online learning. The models only grow on the backend.
This doesn't help anyone but those corporations that have massive funding
to create and train models. They get to decide how the models 'think', what their
biases are, and what topics or subjects they cover. This is no good long run,
but thats more of an ideological argument. Thats not the real problem.
The problem is they've once again gimped the research, chosen a suboptimal
trap for the direction of development.
What interested me early on in the lottery ticket theory was the implications.
The lottery ticket theory says that, part of the reason *some* RANDOM initializations of a network train/predict better than others, is essentially
down to a small pool of subgraphs that happened, by pure luck, to chance on
initialization that just so happened to be the right 'lottery numbers' as it were, for training quickly.
The first implication of this, is that the bigger a network therefore, the greater the chance of these lucky subgraphs occurring. Whether the density grows
faster than the density of the 'unlucky' or average subgraphs, is another matter.
From this though, they realized what they could do was search out these subgraphs, and prune many of the worst or average performing neighbor graphs, without meaningful loss in model performance. Essentially they could *shrink down* things like chatGPT and BERT.
The second implication was more sublte and overlooked, and still is.
The existence of lucky subnetworks might suggest nothing additional--In which case the implication is that *any* subnet could *technically*, by transfer learning, be 'lucky' and train fast or be particularly good for some unknown task.
INSTEAD however, what has happened is we haven't really seen that. What this means is actually pretty startling. It has two possible implications, either of which will have significant outcomes on the research sooner or later:
1. there is an 'island' of network size, beyond what we've currently achieved,
where networks that are currently state of the3 art at some things, rapidly converge to state-of-the-art *generalists* in nearly *all* task, regardless of input. What this would look like at first, is a gradual drop off in gains of the current approach, characterized as a potential new "ai winter", or a "limit to the current approach", which wouldn't actually be the limit, but a saddle point in its utility across domains and its intelligence (for some measure and definition of 'intelligence').4 -

I MEAN, COME ON MAN, WHY ARE DOCS SO HARD TO COME BY? WHY DOES YOUR "CUSTOM SCRIPT" EDITOR LACK BAISIC LINE NUMBERS? WHY ARE YOUR ERROR MESSAGES TELLING ME EVERYTHING BUT THE LINE THE ERROR'S ON, SO I'LL BE HOPEFULL THE ERROR IS IN THE DEV CONSOLE? WHY NOT USE MONACO, SOMETHING, ANYTHING THAT WILL SHOW SYNTAX ERRORS? I'VE WAISTED HOURS ON LITTLE AUTOMATION SCRIPTS!!!! WHY WHY WHY WHY????1 -
I learned to program with the joy of the command line and ASCII rocket ships printed and shell games on GWBasic. It was fat spiral bound manual my Dad gave me when he worked at EDS. My dad then tried to press me to leaning a program for calculating prime and perfect numbers. My dad sort of forgot I was only six and hadn't learned division yet.1

What the fuck is going on ???
How the "intermediate" c# developers can't do a simple null safe average of even numbers in an array ?!
Why they still write loops and shit (without any nul checks ofc) while it can be done in 1 line :
array?.Where(x => x % 2 == 0).DefaultIfEmpty(0).Average() ?? 0
WHY ? Even Junior c# dev is supposed to know that shit4 -
After my first ever "thing" I wrote (see story here: https://devrant.com/rants/2132057/...) fast forward 7 years to my first project when I /* thought I */ knew what I was doing and didn't write just for myself.
Preset:
I worked in a very small company distributing various materials for medical research, many of them bought from manufacturers and then relabelled as if we had produced it. One part of that was to indicate a production batch / lot number. Before I started there, they would just invent a random number on the spot and use that on the new label and somewhere write it down to document that, I at least used an Excel sheet to have numbers prepared and document it on the same line (still crappy but more than nothing). After some time my boss got the idea to have all of that documented in MS Access (because that was the only database he knew). I had just started with HTML, PHP and MySQL in apprentice school around the same time, so I proposed writing an appropriate solution using those and got permission.
-----
I started coding and learnt so much that I didn't need to pay attention at school anymore as I was years ahead of the curriculum (the others were struggling with If-statements and the likes).
When I was done with Version 1.0 of my web application, it was of course still crude as hell. I used html forms to save input (like editor.php -> submit to save.php, do save -> redirect to editor.php), but it did what had not been done before: keeping it all together and force people to do it properly. 2 years later I wrote a version 2, adding features that showed to be useful and with improved structure, as my last project before leaving, and as far as I know, they are still using it, which is at this point 2 years after I've left.
Looking back I would do it differently, but for what I knew back then it was not bad at all.2 -
Another terrible rant from the inhereted Hydra source code. So deep in the dark dungeon of that code I noticed something interesting. They declare this INT32 array with an incredibly long (like 200 values) list of hard coded magic numbers. Something along the lines of:
INT32 array[200] = {-1,0,1,21,4,7,19,33...};
However, the resulting output was incorrect. After spending a fort night and a good chunk of my remaining sanity I had overcone the 437 levels of indirection left by the previous programmers, and narrowed it down to this line. But it looked perfectly fine.
I pull up the diffs and notice someone had checked in a change to the source. I track it to this line and find what the original data had been.
INT32 array[200] = {-1,0,1,2l,4,7,19,33...};
In VS the default font shows l and 1 as fucking identical. Someone had accidentally made that change to 21 from the original 2l and checked it in. I mean I can't really blame them. Who the fucking hell inatantiates a fucking int32 array and peppers in a fucking 2l (long) for no fucking reason?! -
Can we PLEASE once and for all redesign email and texting to be whitelist only?
Seriously, blacklisting doesn't work. We still have assholes that just because they know a line of text or a phone number can harass you forever. It IS harassment and needs to stop. We can always have the option of throw away blacklist addresses, but lets make primary email and phone numbers whitelist only as a standard feature. The business of SPAM would be dead overnight.4 -

If any of you were wondering why all the panic when we keep hearing reports of so few people personally knowing anyone with covid19 symptoms, I think I just figured out why.
So as of yesterday, assume unofficially fatality is 15%. Yesterdays death total was 3861.
If we assume roughly 15% death rate, based on ten days average for a case to recover or die, then the cases that would be recovering today on april 1st would have been infected or started to show symptoms on march 22nd.
At that time there was 32882 cases total in the u.s.
Therefore for april 1st, that would mean by the end of the day today, if the ~15% fatality rate is accurate, there would be at least 4,932 fatalities logged today.
I don't know about you, but here it's almost 9am, not even halfway through the day, and we're already at 4067 deaths.
And now we get to the part where all this shit starts to make sense.
For a long time since this outbreak has started somethings been bugging me and I couldn't place what it was till now.
Why did it seem, no matter how high the numbers climbed, no matter how much this spread 'like the flu', no matter how hard I looked into it, very few people seemed to personally know anyone *in real life* who died or at least came down with this?
I mean we'd all heard the rumors that it was more lethal, and then mums the word, it seemed like media the world over simply except the official "it's only 2% lethal" line. Same as the line about it only infecting people of asian descent.
And it didn't make sense to me why the numbers were so high, and why all the panic if it's just the flu? I knew in the back of my mind it wasn't I just didn't have a specific reason why.
Here it is: This thing is still pretty contagious, but not as contagious as it *could* be with a lower fatality rate. And with a fatality rate at 15%, combine with *just sufficient* spread, it would continue to burn and fester in communities for a year or more until those panic-numbers we see on the news would become a real thing. And then no matter HOW flat we made the curve, it would be x5-x50 times worse than a bad flu.
So we get panic and fake numbers. Because you really don't want to catch this thing. It kills 1 in 6.6. And it spread just enough that it is hard to effectively fight.8 -
Hey everyone :-) - Hope you're all doing well & Staying safe, i just have a question for you all, i have a project i am working on which is a command line tool to track my storage on my PC & laptop, right now it outputs my remaining space, used space and storage capacity :-), it also shows these numbers on bar chart & pie chart - i'm proud of it! :D , its written in Python also - would love to know what other things would you guys add to it? any ideas? id really appreciate it :-) cheers! <336

nothing new, just another rant about php...
php, PHP, Php, whatever is written, wherever is piled, I hate this thing, in every stack.
stuff that works only according how php itself is compiled, globals superglobals and turbo-globals everywhere, == is not transitive, comparisons are non-deterministic, ?: is freaking left associative, utility functions that returns sometimes -1, sometimes null, sometimes are void, each with different style of usage and naming, lowercase/under_score/camelCase/PascalCase, numbers are 32bit on 32bit cpus and 64bit on 64bit cpus, a ton of silent failing stuff that doesn't warn you, references are actually aliases, nothing has a determined type except references, abuse of mega-global static vars and funcs, you can cast to int in a language where int doesn't even exists, 25236 ways to import/require/include for every different subcase, @ operator, :: parsed to T_PAAMAYIM_NEKUDOTAYIM for no reason in stack traces, you don't know who can throw stuff, fatal errors are sometimes catchable according to nobody knows, closed-over vars are passed as functions unless you use &, functions calls that don't match args signature don't fail, classes are not object and you can refer them only by string name, builtin underlying types cannot be wrapped, subclasses can't override parents' private methods, no overload for equality or ordering, -1 is a valid index for array and doesn't fail, funcs are not data nor objects when clojures instead are objects, there's no way to distinguish between a random string and a function 'reference', php.ini, documentation with comments and flame wars on the side, becomes case sensitive/insensitive according to the filesystem when line break instead is determined according to php.ini, it's freaking sloooooow...
enough. i'm tired of this crap.
it's almost weekend! 🍻1 -
So we now do continuous deployment to a development environment. Once a PR gets merged it gets deployed there. We then have to manually deploy to staging every so often.
We did this because QA wined that the Dev was constantly breaking Staging, when we contentiously deployed to that.
So now we have a staging instance that is always behind. Which isn't big deal, because its supposed to be stable right?
Well now the stupid fucking QA team is always making mountains of tickets and noise for stuff that is already fixed on the development instance.
Fucking shit that they message me about, or have to call me about. "Hey let me tell me about this thing I found." And then I'm like I already fixed that thing last week.
So it seems to be wasting everyone time to not just CDCI into staging. I have to wait weeks to retest my bugs on staging. To make sure that some other stupid fuckeshir on my team didn't undo or break my fucking fix. Shit keeps getting kicked out of QA Review. Fuck. lol.
Then there like I can update the thing on the database through the front end tool. Well tough shit buddy, your going to have to wait a week unti next staging deployment to see if that tool is fixed. This is your fault for fucking up our pure CDCI with your ideas. Now everything takes longer for everyody.
To sum things up. Some dumb bug makes it into the manual staging deployment and gets fixed an hour later. Doesn't get deployed until next fucking week. QA makes a bunch of noise about it. A thing that is fixed and in the pipe-line.
Also a dumb fucking bug will make it into staging, lets say a critical front-end back office tool that needs to send numbers to the backend, they send a fucking string instead of a number and break it. Now we have to redeploy the tool and backend to staging because there related. Then if we deploy backend we have to deploy the client facing site too. since it also depends on backend.
Its a fucking hassle.
Now if the fucking DevOps guy could do his job, and make a god-damn deploy button for all the staging servers that would be great.1 -
Wherein I disprove Goldbachs Conjecture (in one specific case)
golbach conjecture:
every even number is the sum of two primes
lets call the primes p and q
lets call our even number p+q=n
we can go further by establishing two additional variables
u=p-1, v=q-1
therefore every even number is the sum of u+v+2, according to goldbach's own reasoning.
in the simplest case...
p=2, q=2, p+q=4
u=1, v=1, u+v+2 = 4
We can therefore make a further conjecture in the simplest case every sum of two primes, less 2, is the sum of two composites. This likely has connections to the abc conjecture for a variety of reasons. But leaving ancillary discussion aside for a moment...
We can generalize to a statement that every even number is the sum of two odd numbers. And every odd number greater than 1 is the sum of an odd number and an even number.
Finding an even number that is not the sum of (p-1)+(q-1) would therefore be equivalent to disproving the goldbach conjecture. Likewise proving every even number is the sum of (p-1)+(q-1) would be the equivalent of proving it.
Proving all even numbers greater than 2 are the sum of two composites + 2 would be proof of goldbachs conjecture, and finding any example or an equation that proves an example exists such that *some* subset of even numbers are NOT the sum of two composites +2, would disprove the conjecture.
Lets start with a simple example:
2+2=4
because 4-2=2, and two is not the sum of two composite numbers goldbachs conjecture must ipso facto be false.
QED
If I've wildly misapprehended the math, please, somebody who is better at it, correct me.
Honestly if this is actually anything, I'd be floored to discover no one has stumbled on this line of reasoning before.8
