The story of the $500,000,000 error.
In 1996, an unmanned Ariane 5 model rocket was launched by the European Space Agency.
Onboard was software written to analyze the horizontal velocity of the spacecraft. A conversion between a 64-bit floating point value and a 16-bit signed integer within this software ultimately caused an overflow error just forty seconds after launch, leading to a catastrophic failure of the spacecraft.
That day, $7 billion of development met it's match: a data type conversion.14 -

Ever wanted cheat codes to devRant? Well, that's weird. But here you go, I guess.
Since the avatars do not use any external assets (Such as images), all avatars are generated. To be friendly to people who want to make third-party devRant clients (such as devRantron), avatars are generated server-side, so that the assets don't need to be distributed, and third-party programmers don't need to work out rendering avatars.
But this allows you to cheat a little.
The devRant avatars API works like this: you request a really long URL from the API, specifying the IDs of each cosmetic item the user has active, and it returns a PNG file. But you don't need an auth token to generate an avatar (which makes sense), so the avatar API is essentially a sandbox you can play around with if you have the time and patience.
You can write a really good avatar previewer with this knowledge, and see your avatar with a white tiger, even if you don't have the ++s

I just had the most intense nerdgasm of my life.
So I'm learning NodeJS (11/10, super fun, totally recommend) and I already had a chat script written up but it was only available to my LAN. Im hosting it using my Raspberry Pi Zero, which is surprisingly fast, and obviously sips power. Anyways, I FINALLY figure out port forwarding (Comcast made things harder, as per usual) and for the first time in my young life, I chatted with someone half way across the country... Using the hardware I set up, running the script I wote, on the network I configured.
I could have sworn I was drooling.
Today was a good fuckin day.19 -

A story of love, loss, and devRant.
My favorite sunglasses were a victim of hurricane Irma. They were sitting on the park bench when a powerful gust of wind blew them onto the cement floor, where both lenses were fucked right where I look out of them. I bought these sunglasses at Disney with my family and have not stopped wearing them since. I was pretty upset.
Enter devRant. Sad and without sunglasses, I hoped that virtual ones might suffice. Lo and fucking behold, in the profile editor, there they were: my exact sunglasses, even with the choice between silver and gold. Absolutely fucking perfect. Made my day.

People on Stack Overflow are SUCH FUCKING ASSHOLES
"You didn't show us where you declared this unimportant array, please review this article for how to ask questions"
My question doesn't concern the array, my question concerns how the system works, all code I provided was only for clarity. Read my fucking question you arrogant asshole. You have lots of points, fine, go tell your mother, but you assume I don't know how to ask a question which you clearly did not read.8 -

"Fuck JavaScript, its such a shitty language" seems to be quite a common rant today. It seems as if JS is actually getting more hate than PHP, which is certainly odd, considering the stereotype.
So, as someone who has spent a lot of time in JS and a lot of time elsewhere, here are my views. Please, discuss your opinions with me as well. I am genuinely interested in an intelligent conversation about this topic.
So here's my background: learned HTML/CSS/JS in that order when I was 12 because I liked computers. I was pretty shitty at JS until U was at least 15, but you get the point, Ive had it sploshing about in my brain for a while.
Now, JS certainly has its quirks, no doubt, but theres nothing about the language itself that I would say makes it shitty. Its a very easy leanguage to use, but isn't overdeveloped like VB.net (Or, as I like to call it, TheresAFunctionForThat)
Most of the hate is centered around JS being used for a very broad range of systems. I doubt JS would be in the rant feed so often if it were to stay in its native ecosystem of web browsers. JS can be used in server backend, web frontent, desktop and mobile applications, and even in some system services (Although this isn't very popular as of yet). People seem to be terrified that one very easy to learn language can go so far. And, oh god, its interpreted... How can a system app run off an interpreted language? That's absurd.
My opinion on JSEverything is that it's progress. Thats what we're all about, right? The technologies already in place are unthreatened by JS, it isn't a gamechanger. The only thing JS integration is doing is making tedius and simple tasks easier. Big companies with large systems aren't going to jump ship and migrate to JS. A startup, however, could save a fucking ton of development time by using a JS framework, however. I want to live in a world where startups can become the next Google, because technology will stagnate when youre trying to protect your fortune, (Look at Apple for fucks sake) but innovation is born of small people with big ideas.
I have a feeling the hate for JS is coming from fear of abandoning what you're already doing. You don't have to do that. JS is only another option (And a very good one, which is why it's becoming so popular).
As for my personal opinion from my experiences... I've left this part til the end on purpose. I love programming and learning and creating, so I've never hated a lamguage, really. It all depends on what I want to do. In the times i've played arpund with JS, I've loved it. Very very easy. The idea of having it on both ends of web development makes a lot of sense too, no conversion, just direct communication. I would imagine this really helps with speed, as well. I wouldn't use it in a complicated system, though. Small things, medium size projects: perfect. Running a bank? No.
So what do you think about this JSUniverse?13 -
Interesting thing I did yesterday:
This is a program which loops over every word in the wamerican word database and checks if the username is available on the Mojang servers, thus, this is a Minecraft OG username finder, and it works beautifully.
I'm checking 72,000 words, the only thing is I can only check one per second, so the entire process takes about 20 hours. Any usernames which are available are sent into a text file for later viewing, and it remembers which word it looked at last if you can't have your computer on for 20 hours straight.
Very happy! Found quite a few good names so far!

I had to open the desktop app to write this because I could never write a rant this long on the app.
This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.
Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.
[START RANT]
"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."
From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table
The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.
The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:
array[index]
Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.
Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:
a = {1, 5, 9};
a["hello_world"] = "whatever";
a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.
This is the difference between indexing and lookups. But you may say,
"Algo! If I do this:
a = {"first", "second", "third"};
print(a[1]);
...then "first" appears in my console!"
Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:
Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):
el = arr + (sz * i)
This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.
That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.13 -

I always use brackets for clarity even if there is only one statement inside them
if (boolean){
function ();
}
Cus it's so much easier to read, and if I need to add statements after the if I don't need to remember to add brackets. Plus the else may need brackets and an if with no brackets but an else with brackets looks awful.14 -

This one hits home a bit.
So my friend from my first college hits me up, asks about what's going on and shit. It's all chill, we took a bunch of programming classes together, so it we weren't intimate friends just kinda familiar with each other. He says he's having trouble finding work, they all turn him down due to a lack of experience. I suggest we work on a project together. Anything. He thinks it's a good idea and we plan to meet up.
We meet up, long story short decided on an Android app. I failed setting up git but whatever, I'll fix it at home. He seems excited, I'm excited...
...Never heard back from him again. Won't answer texts, Skype, anything.10 -

My first real "rant", okay...
So I decided today to hop back on the horse and open Android Studio for the first time in a couple months.
I decided I was going to make a random color generator. One of my favorite projects. Very excited.
Got all the layouts set up, and got a new color every tap with RGB and hex codes, too. Took more time to open Android Studio, really.
Excited with my speedy progress, I think "This'll be done in no time!". Text a friend and tell them what I'm up to. Shes very nice, wants the app. "As soon as I'm done". I expected that to be within the hour.
I want to be able to save the colors for future reference. Got the longClickListener set up just fine. Cute little toast pops up every time. Now I just need to save the color to a file.
Easy, just a semicolon-deliminated text file in my app's cache folder.
Three hours later, and my file still won't write any data. Friend has gone to sleep. Homework has gone undone. My hatred for Android is reborn.
Stay tuned, the adventure continues tomorrow...11 -

This spring I was working on a library for an algorithm class at uni with some friends and one of the algorithm was extremely slow, we were using Python to study graphs of roads on a map and a medium example took about 6-7h of commission to finish (I never actually waited for so long, so maybe more).
I got so pissed of for that code that I left the lab and went to eat. Once I got back I rewrote just the god-damned data structure we were using and the time got down to 300ms. Milliseconds!
Lessons learned:
- If you're pissed go take a walk and when you'll come back it will be much easier;
- Don't generalize to much a library, the data structure I write before was optimized for a different kind of usage and complete garbage for that last one;
- Never fucking use frozen sets in Python unless you really need them, they're so fricking slow!3 -
Juste design a new algorithm to evaluate the chance of a project (any kind of project) will exceed the budget (time of cost). This algorithm been proven to be right almost all the time.

I just experienced the opposite of rant.
I spent 1 entire day ranting about a algorithm I couldn't write with no issues, it occupied all my mind and got me pissed of.
And today, I rewrote it entirely, and it works perfectly everywhere.
I was like : "No it can't work here. Oh ok", "And here's the bug ! No ? Nice.", "Don't tell me it'll work here. I'm a God".
That's why I love being a dev :D

A LOT of this article makes me fairly upset. (Second screenshot in comments). Sure, Java is difficult, especially as an introductory language, but fuck me, replace it with ANYTHING OTHER THAN JAVASCRIPT PLEASE. JavaScript is not a good language to learn from - it is cheaty and makes script kiddies, not programmers. Fuck, they went from a strong-typed, verbose language to a shit show where you can turn an integer into a function without so much as a peep from the interpreter.
And fUCK ME WHY NOT PYTHON?? It's a weak typed but dynamic language that FORCES good indentation and actually has ACCESS TO THE FILE SYSTEM instead of just the web APIs that don't let you do SHIT compared to what you SHOULD learn.
OH AND TO PUT THE ICING ON THE CAKE, the article was comparing hello worlds, and they did the whole Java thing right but used ALERT instead of CONSOLE.LOG for JavaScript??? Sure, you can communicate with the user that way too but if you're comparing the languages, write text to the console in both languages, don't write text to the console in Java and use the alert api in JavaScript.
Fuck you Stanford, I expected better you shitty cockmunchers.

When you don't want to explain what you've done with application's code base so you play the "algorithm" card.
Boss: tell me about the new release.
Me: updated the search algorithms boss.
Boss: cool. Release!
Me: 😎 -
Writing some algorithm:
me: *codes for half an hour*
"hmm... isn't working... wait wtf this isn't right..."
me: *codes for an hour again*
"still not working hmmm... wait what no this isn't supposed to work..."
me: *codes for a few hours*
"still not working God damnit.... it's supposed to work now..."
me after another few hours: MOTHERFUCKER CAN YOU START FCKING WORKING FUUUUUUUUUUU1 -
We were going over man in the middle attacks today and I honestly just could not stop thinking about that SpongeBob episode where Squidward keeps intercepting the bubble messages between SpongeBob and Patrick and it was so dumb that I could not stop smiling.3

I FUCKING HATE THE INSTAGRAM ALGORITHM FOR SUGGESTED POSTS TO EXPLORE.
You piece of shit; I have NEVER EVER looked at pictures of nature, but I get a shit load of suggested pictures of nature. Can't forget the time they spammed it with memes in a random language I can't read.
OH. AND LETS NOT FORGET YOUR TIMELINE ALGO. IT'S JUST AS SHITTY.
"Hmm. Let him see a picture posted a few minutes ago or one from a week ago? Fuck it, a week ago it is!"7 -

I have not researched it so I'm not sure if this is a widely known thing but I figured out a sort of hacky way to get a max integer value:
-Declare an unsigned int.
-Subtract 1
-Divide 2
That is your max signed int value
int main(){
unsigned int a = 0;
a--;
std::cout << a / 2 << std::endl;

Facebook's algorithm is so bad that I can't believe that. In the past few days I marked ~20 posts from the same person with the same/similar content as "Hide post - see fewer posts like this". And now, not that I see fewer of these posts, they are literally throwing all such posts of that person to my feed. I know that I can unfollow this person but I don't want to. I just want to filter out these specific posts (they are all the same, some link, image of an old black and white photo and some description).8

So during a test I was to write an algo of binary search tree traversal and I got a zero....Why? Cause I wrote a recursive algorithm and also because I wrote "English" instead of pseudocode, which she thought is called algorithm and on showing her the exact same recursive Algo on various websites and books, she just declared all of them wrong1

I think God is a developer. I have to say a most impressive feat, even for God, is the idiot algorithm. It has persisted through millennia of attempts to remove it, but it just keeps refining itself. While it's incredibly brief, its functions are yet to find an environment in which they cannot operate. It's full adaptable to any task, impressively modular, and self replicating.
No matter how what problem you present it with the idiot algorithm can always find a solution. It never leaves well enough alone. It can even give you an answer before everything is fully processed!4 -
A funny story I just remember while my code is compiling :
Back in high school, in Math, we were taught how algorithm works, and we made some exercises with practical examples.
I didn't know anything about it back then, so was curious. Was pretty fun, but one day, my teacher said that a IF is a loop. I said "no, this is a test" but she keeps saying that it was a loop, ignoring me (I dunno if she actually heard me) and no one actually noticed it as she repeated it several times (while I was saying that it's not). I just gave up trying to say it's wrong.8 -
Anyone played Human Resource Machine yet? It's fun to solve and optimize these algorithm puzzles after a hard work day.
Does anyone know other games like this?5 -
Hmm, this gameboy emulator is pretty cool. I have been playing Pokemon Sapphire for about two hour-
Well shit now I gotta make Pokemon MMORPG, because my excitement said so. God damnit.
(Friend seemed very excited about the idea too. I love being able to make stuff for just me and my friends)5 -
One of my favorite things to do in Secondary School was to go around telling people I had written a program that uses the 'Doomsday Algorithm' which sounded really cool and always scared those who didn't understand it.
Truth is, the 'Doomsday Algorithm' is just an Algorithm that used to determine the Day of the Week of a given date.
I wrote this when I was 13/14 years old and I'm still super proud of it today.... well I mean I probably would be if I could read my own code.1 -
This is more of a story than a rant, but it has some rant-ey elements, so whetever...
I work for a pretty big company. Several departments, teams, many different markets...so it's a big orchestration. The programming department (aprox. 5% of all employees) is the core of the whole company, because everybody else uses software we've written...(a bit off topic, the point is there are a lot of people)
So today, I got assigned with a side-project. The project spec arrives, and as I read through it, I start realizing that upper-management whats me to build an app to fire people instead for them. The app is supposed to track salary, connect with Trello (for departments that use it) to track finished tasks, track sick days, work attendence...a lot of stuff, and at the end, if the situation requires, spit out a person that is of least benefit to the company, to be fired...
Now from coding perspective, this will be very interesting and fun to build, but from a moral standpoint, I'm a bit woried...simply because, indirectly, I'm firing those people. Because, the way I tune the the app(specifically the algorithm that weighs the value of an employee to the company) will cause certain people to get fired...
So I'm woried I'm gonna have a small breakdown when the app goes live and I see someone saying goodbye to theie colegues of something similar...heck, the app might even spit out my name some day(I should probably add a tiny if statement somewhere in there :) )
What do you guys think about this, from a moral standpoint? Would you be okay with building something like this?
(Sorry for the long post :/ )8 -
I’m stressing out man. I can look at let’s just say a sorting algorithm for now. I can look at that insertion sort and I can understand what’s happening, but if you were to tell me I was supposed to be able to write that just based off a description I couldn’t. I need to be able to design and understand algorithms but I don’t know where or how to start. There was some course I was gonna try and see what that does. I put aside JS completely to focus on C# but I’m just stressing out over here. I learned the basics of C# although I feel like I’m learning it wrong but I’m moving on to SQLite and it’s my first Database experience and it’s confusing me and I also don’t know how I’m going to be able to use it for my future applications yet I’m just expecting too much out of me idk I love programming but sometimes it’s a cruel mistress13

I’m really liking the Algorithm Design Manual so far, except for the fact that there’s not a glossary somewhere for “random mathematical symbols you have probably never had to deal with but we will use in psuedocode examples”1

Actually what I did was I split the challenge into smaller piece and posted the miniature on stackoverlfow. 2 minutes later I stood in front of everyone explaining my solution. -

Few days back, I developed an app for a client where users can buy textile designs online.
The designs to be uploaded on the server must be square to display correctly on the app. so I had to make them square manually (by either pattern repetition or by filling extra space).
I was like "fuck me!", 800 design image to make it square and each takes like 1 and half minute. I did uploaded 30 to 40 images and then...
I got really frustrated and I was lazy to make more designs square anymore.. So I developed an algorithm that would identify the type of design and then it automatically makes it square by self decision.
so that was my little anti-laziness for my big laziness. -
There should be algorithm in DevRant to identify duplicate photos - same memes/photos posted in the last 48hours or less.

Another GeeksForGeeks rant
Wisecrack got me a bit interested in primes (just a passing interest). I looked up their python implementation of "Sieve of Atkin". Wow, is it bad.
First of all, they use PascalCase instead of underscore_natation so that's points off right there.
Their function takes a limit as a parameter (pretty obviously).
Their program breaks if you pass a prime number as a limit. That's right, if you give it a 2, it breaks. Pretty pathetic.
Reading the comments, their Java implementation is wrong too.
For fucks sake guys, if you're going to have an algorithm blog at least write good algorithms.6 -
Trying to make my first genetic algorithm program "to be or not to be" in javascript.... (coming from java and experimenting a bit)
Can't even get past instantiating a function/class Gene.js file into the main.js file. -_-

Update to Doomsday !rant which can be found here: https://devrant.com/rants/1000628
Hey Everyone I'd like to let everyone know that I finally found the original file for my Doomsday Algorithm and thought it would be fun to show you the dirtiest code I've ever written (I was 12 when I wrote it).
here is the github link, https://github.com/LiamHolmesEPD/... , and I'll likely update it will more cleaner languages in the future.2 -

I am a cs student at first class. Obviously we take an algorithm lesson. However, despite we have learned all things related to OOP , we didn't even learn switch case statement not even bubble sort algorithm or anything related to the algorithms. Because of that in my free time I learn this stuff individually. I know we will learn these things in the second class but it doesn't make sense to program anything without knowing them because you need to use them. You can use standard library but that doesn't mean you don't need to know how that works.

I have experiences and I am able to show what I've done,including spare time projects that I do during non-working hours. But i were given a algorithm question in the interview, that just marked the end of my 2 years efforts. I want to shout to the interviewer next time please don't write lies on your description, state it clearly that someone have to answer algorithm questions to get the job, so that I won't bother to apply and attend to the interview. Thanks!2

The Devrant Algorithm not only reads everything and then sort by sarcasm but sees everything and then sort by sarcasm.
Even puts Google's cloud vision to shame.

If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?
Now according to
https://en.wikipedia.org/wiki/...
"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"
Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?
Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."
If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.
Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?
Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?
I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.
It's all unknown unknowns to me. -
