what the hell is this talking about when it says it prefers you to let it generate the salt automatically? if the function is generating a random salt every time how are you supposed to store the salt so you know how to get it to use it the next time a user enters their password and you want to check if its correct? you'd have to get lucky and get the exact same random salt, no?

>What are you working on, /g/?
A Youtube to mp3 converter in Python.

I'm new to programming and I decided to write it as my first real "project" with the aid of youtube-dl and ffmpeg. It's nothing more than a simple script that links youtube-dl and ffmpeg, I'm sure anyone experienced could do it in a couple minutes but I had so many problems getting it to work. After 5 hours reading through documentation and source code and failure after failure it finally worked so I'm pretty happy.

It has a built-in proof system so you can prove your program is correct at compile-time. Of course, there are external proof systems too, so it isn't unique in that regard. It is a vehicle for dependent types research, and dependent types allow you to verify things that would normally be verified at runtime (example: type-safe printf).

>>58694162
>W-why is this?
You use 0 to read from memory, not R, because that program uses atoi() to parse arguments, even ones that don't really need to be numeric. Because its author is stupid.

What you actually get when you read from some random memory isn't always what you expect. Sometimes it can just kill your program (if you try to read from memory that isn't mapped). Other times, it works but is just zero pages. Virtual memory means you don't read real memory, or at least not using physical addresses.

The program doesn't check for errors. Bad Program! Bad Programmer!

>>58695267
the % and ^ operator do the same thing but ^ has lower precedence then *,/,+,- so if I write x + x^2 then it evaluates it to 4x^2 since it does (x + x)^2. I'm not using literals since I'm lazy.

What kind of codes are more desirable?
1. Short, concise and genius code that takes a while for a fellow project contributor to fully understand. (ie nested ternary/recursion etc)

2. Long, expanded and dumb code that is very easy for a fellow project contributor to fully understand. (ie. dumb if else, while, switch etc)

I think (2) makes a project large but maintainable and forkable. But it does not give any 1337 cred.

>This is what I wrote to test it.
Read up on how to do real software testing. Since it is java and just a single class, look at junit that most people use for doing unit testing.

If you do that, you'll write more code, but it will be BETTER code. Nobody sensible tests by just printing things out and eyeballing it; it's far too hard to do it that way.

Fucking stack frame analogy

" As each function is called, it may call other functions, which may call other func-
tions—all before any function returns. Each function eventually must return control to the
function that called it. So, we must keep track of the return addresses that each function
needs to return control to the function that called it. The function call stack is the perfect
data structure for handling this information. Each time a function calls another function,
an entry is pushed onto the stack. This entry, called a stack frame, contains the return
address that the called function needs in order to return to the calling function. It also con-
tains some additional information we’ll soon discuss. If the called function returns, instead
of calling another function before returning, the stack frame for the function call is popped,
and control transfers to the return address in the popped stack frame.
Each called function always finds the information it needs to return to its caller at the
top of the call stack. And, if a function makes a call to another function, a stack frame for the
new function call is simply pushed onto the call stack. Thus, the return address required by
the newly called function to return to its caller is now located at the top of the stack.
The stack frames have another important responsibility. Most functions have auto-
matic variables—parameters and some or all of their local variables. Automatic variables
need to exist while a function is executing. They need to remain active if the function
makes calls to other functions. But when a called function returns to its caller, the called
function’s automatic variables need to “go away.” The called function’s stack frame is a
perfect place to reserve the memory for automatic variables. That stack frame exists only
as long as the called function is active. When that function returns—and no longer needs
its local automatic variables—its stack frame is popped from the stack, ..."

I could use some tips for an animation algorithm.
I have an animation that consists of 6 distinct frames, but I want each frame to have multiple shots (e.g. 2s or 3s). Within a loop, how could I set up an algorithm to give every two adjacent indices (of the animation array) the same image?

Conway's game of life in C++ using SFML. Never programmed it before and I feel like it's something every programmer has to make eventually. Right now I have the window drawn and have figured out how to draw some stuff and now's the time for the fun part which is seeding the grid and then doing generational logic.

Is storing all the cells in a vertexarray of quads a reasonable approach to start with, or is there a better way that I'm unaware of? I'm still new to C++. Pic related it's what I've got so far. The grid is a single vertexarray and so are the quads. I'd like to get a basic implementation working and then work on optimizing it.

SDL is a multimedia library. It handles graphics, windowing, input, and audio all under one library. It's also a lot less of a pain in the ass to use. Seriously, try writing your program in raw OpenGL and OpenAL, then try writing it in SDL. You will be a lot more productive with SDL.

I had roughly 1100 cat images around the time the /dpt/ was born. I've no idea how many I have now.

>>58696978
But it's still one line of source code.

>>58696956
compare the size of their standards reports

>>58696978
Yeah, which is why the images you use have such old time stamps. Or are you suggesting /dpt/ was born relatively recently? In which case you are even more retarded.

>>58696988
No, it isn't. Did you not read the conversation?

>>58696995
Ah yeah, I'm a time traveler

>>58697016
Please prove this you fucking retard.

ghc compiles the code to quantum state in which all outcomes are predetermined with infinitely fast runtime

>>58697001
Yes, it is. Did you read the other posts?

I'm not sure what you're upset about. /dpt/ was conceived summer 2011, IIRC.

>>58696945
I'm trying to figure out simply which columns need to be condensed into just one column (columns like "data 1997, data 1998", etc.)

But the first problem is I can't fucking Open it to see what the title are. I'm going to just try reading the raw XML myself and only the first few lines using head. I'm doing this on my storage server too so it's slower than my ssd server

They must be able to open it in some way to have entered the data in the first place. Just for information gathering, have you tried opening the sheet on their system?

>>58697035
Yup.

i get the "most posters here are animals" joke you're trying to make but could you please post anime instead? at least it's more related to the subject.

>>58697019
this is true. i actually implemented that myself.

Yes, I did. I also wrote the code, which is four lines of Haskell that define four functions.

Where did you go wrong? :)

>>58697075
>>58697077
Bravo

>>58697044
already planned that after I get a basic system set up.

>>58697048
they open their sheet very slowly on an iMac. My server has 256mb ram and is not used for processing huge files like this all at once, just simple web serving stuff

>>58697057
Not much anime is programming related. I'll admit Nagato is an exception.

>>58697075
>>58697077
Nicely done, guys.

>>58697125
Why the fuck would you be processing it on a server with 256mb of RAM?

>>58696925
>not allowed to point out that the US system is inherently stupid because it might upset the burgers

Yeah nah.
It's not even a properly capitalist system either, otherwise you'd be throwing money at people studying subjects that lead into understaffed sectors.
Except nobody is doing that, and they still fucking wonder why the staff supply doesn't meet the demand.

>>58697125
>how do they open such a ridiculous file?
>very slowly
I chuckled.

gib algorithm books pls

>>58697218
>It's not even a properly capitalist system either,
I don't think any sane person will claim that it is. Your initial point is blatantly false by the way.

Any ideas about what the fuck should I create? I have some electronic parts and a few toys that I could make use of to build something, but I don't know what.
Preferrably, I'd like to do some random gadget for my room that's not really useful but might be cool.
I feel like there are lots of things I can do, by I am held back by being able to waste my time on other pointelss shit.

>>58697164
Cause 256mb is all I have?

>>58697248
I'm not >>58696897
Making education unequivocally free is almost certainly a bad idea, all degrees are not anywhere near equal.

But charging someone who wants to become a doctor or a nurse tens of thousands of dollars just so they can do their job saving lives is piss fucking poor in the long term.

I'm all for charging the shit out of fuckers who want to waste 3 years of their life reading literature or studying politics though.

>>58697125
Anyway, if you want to gather information about the sheet, just open it on their iMac. Navigate through it a bit until you get the idea, then try to digest it programatically.
