First for Fortran

how to programming, I have this

let screenshotPos = takescreenshot (30,300)
let mousePos = getMousePos

let rec jumba sPos mPos diff =
    match diff with
    | x when x >= 30 -> jumba screenshotPos mousePos (screenshotPos - mousePos)
    | _ -> 0

jumba screenshotPos  mousePos (screenshotPos - mousePos)

when running it seems like the screenshotPos and mousePos expression is only evaluate once, anyway to have it always evaluate when calling it inside the recursive function?

>>61516478
just checked
you're using screenshotPos and mousePos inside the function body
but those are the outer variables, not the bound variables/the parameters - those are sPos and mPos

dunno if F# compiler has it, but GHC (Haskell compiler) has an error message for unused bound variables that would have reported this

Coming along nicely. Neat. Are you designing the GUI yourself or using a library?

What are you using to render? A simple 2d library or are you doing opengl?

>>61516786
Just SFML. I do wish I was using a library to handle some of this stuff for me, but I'm pretty sure that I'd have to seriously work around any standard GUI library. I'm hoping I can get the UI stuff out of the way soon and begin working on real mechanics

>>61516485
It's computer science related. Many programmers use computer science consciously or unconsciously.
I'm not sure we can just consider tangentially related topics appropriate for dpt. Why not have computer setups be related to programming then? It's something virtually all programmers have and use.

Not exactly. This has been going on forever.

just sit down close all your open windows and make yourself do 15 minutes worth of work
it takes a person an average of ~15 minutes to get "into the zone", or what scientists call "flow". after you enter that state, hours fly by and you'll have made a shit ton of progress

doing this is literally the only way I get anything done lol

I think it's how they're designed around practicality to a very fine detail and they're rugged. High end power tools are also very cool. Toughbooks are also cool.

What's the equivalent in programming? Is there any? Programming has always been a very effeminate craft to me. Not rugged, more focused on elegance.

I live with my mother right now, and she can't stand guns. I'm going to be moving on campus for my PhD, and they don't allow guns there either.

When I finally have a house onto my own, I'll be getting a few guns. I want an MKA-1919, which is a Turkish made semi-auto shotgun. You could say it is to the AR-15 as the Saiga 12 is to the AK-47.

You can definitely rent guns at ranges for shooting. Gun stores let you handle unloaded firearms and examine them, even going so far as to allow you to function check them.

It's odd. I think it's mainly about the concern of risks. Similar to how people don't mind other people flying personal planes but they don't want other people to fly a Boeing without qualifications. Even if they're not a passenger.

I'm opposed to letting humans drive cars outside of extreme circumstances. So I can relate.

My workflow? Umm...

Sublime Text and GNOME Terminal are open at all times, regardless of whether I'm programming or not. Typically I use either Ruby or C (or C++) for most tasks, unless I feel like tinkering around with some other language. Any C or C++ program that consists of more than one file will typically be built with CMake or Make, same if I am forced to use Java for some reason. I keep Firefox open with documentation for whatever I'm working on under a single tab tree. Can't really say much more beyond that. I like to test things out in a Ruby REPL to see if they make logical sense if I'm implementing some really weird algorithm, and sometimes I'll bust out a pencil and paper if I need to reason about it spacially (e.g. stuff involving graphs and arrays, particularly if I'm trying to avoid off by one errors on array indices).

I also have an extension in Sublime that allows me to evaluate Ruby code and place the output into the editor. I will sometimes use it if I want to generate a fuckload of code, typically C. Really, who needs templates when you can use Ruby as your preprocessor?

>I'm opposed to letting humans drive cars outside of extreme circumstances. So I can relate.
why does no one else understand this
cars should never have even been invented and although it would be bad if they were to start disappearing one by one (because it would create a global power dynamic which would lead to mass genocide) we should make it our business as a species to find a way to destroy them all simultaneously with high precision
i feel similarly about guns
and all weapons actually
those cart things that horses tug around are okay though

>>61517314

>all weapons actually
Would you prefer we go back to eating bone marrow of animals that we didn't even get to kill ourselves?

>>61517345
that presumes all modern technology which war and hunting has enabled would cease to exist along with the instruments of war and hunting themselves
that is not what i am proposing at all and would easily be even worse than allowing weapons to continue existing as a concept, which is already pretty bad

You can't hunt without a weapon, Anon. Even ignoring guns, these aren't the only "weapons" we've used to hunt. Spears, bows, crossbows, slings... these all count as weapons, and would have to go away.

>You can't hunt without a weapon, Anon
Dig a hole. Cover it up with branches. Chase animal over it. Wait.

Do you consider rocks weapons too?

The way humans used to hunt (and some still do) is that they'd chase animals until they got tired (humans have the best endurance out of any land creature), and then stone the exhausted animal. I guess depending on the animal you could strangle it if you're going to exclude stones and coconuts.

idk about this specific case, but it definitely does have that issue when using unions because it doesn't use case to parse identifiers. so the following code will create a bug:

type t = Ab | Ac | Ad
let x = function
  | Ab -> 1
  | Ac -> 2
  | Ad -> 3
  | Ae -> 4 (* No Ae member *)

Is this a joke? You have chronic anemia and you just live with it?

Anyway I realized I mixed up veganism with vegeterianism.

You're going to need to drink 6 glasses of milk a day to stay healthy anon. Drink those 6 glasses of milk a day and the anemia should go away in a few weeks.

>>61517682
People bring this up must be retarded.
Calfs get sustenance from milk. Babies (and I'm confident they knew not just babies can) get sustenance from milk.
So you try making the animal that can live off grass and other plant life you can't live off sustain you instead of a calf.
I don't know how cheese was originally conceived but the problems of preserving milk must have made people pay close attention when a preservative method was discovered. It's not that strange.

People who find this odd should be amazed by the concept of counting things.

Gonna be honest, I don't think my ex would have dated, or even respected me, were I a vegetarian.

>There are substantially more female than male vegetarians, bigger pool to date
You know there's substantially more women that eat meat than vegetarians, right? You know vegetarian girls will date meat eating men, right?

>Good for you and healthy, shes guaranteed to not be fat
It is very, VERY easy to get fat on a vegetarian diet. Do you know why most people get fat these days? We consume several times the WHO recommended maximum daily intake of sugar.

Fat, on the other hand, is not as bad for you as you think, depending on the type of fat (although I tend to eat lean meats anyways).

>>61517682

>up her butt
Nah, not their butt. They were using the internal organs of various animals as a means of storing food since preservation technology wasn't that great. Put milk in and accidentally leave it sitting for a few months. Oh hey, it turned into something nice.

Incidentally, cheese is the fucking shit. I remember making a calzone with ricotta, broccoli, chicken, and an Alfredo sauce made with a fuckload of Parmesan. Like sex in my mouth.

>>61517892

The problems with C++ are that it's designed by committee and intended to retain (mostly) backwards compatibility with C. The result is a disorganized mess of a language with a bunch of features that don't seem like they fit together, at least not in their syntactic style. The only way it could be fixed would be to remove features. This won't happen because it would break compatibility with existing codebases, and because C++ programmers have grown to enjoy having stupid amounts of power.

Rather than trying to fix C++, you should use something else.

The main problem with C++ is reading other people's C++. Since the language is so large, the mental overhead of keeping track of implicit behavior (templates, overloads, different types of constructors, RAII. polymorphism, etc) becomes stupidly large.
I think the additions of Concepts, Modules and Metaclasses should help a bit with managing this complexity, but we'll see.
However, I don't think we should be looking for a successor to C++, but instead use domain specific languages.

currently trying to make pong in in sfml using c++ and am messing around to see how i can get the ball to work.

i have this code:

int ballmovement = 1;

if (ballmovement == 1) {
            ball.rect.move(0.08f, 0.0f);
        }
        
        if (p2.Collision(ball)) {
            ball.rect.move(-5.0f, 0.0f);
            ballmovement = 0;
            std::cout << "P2 Collision" << std::endl;
        }

however when the ball collides with the paddle, it keeps going in the direction from the first if statement and doesn't stop and go in the other direction even though i set the variable to 0. i tried using a dowhile statement but that crashes the program immediately on startup for some reason. anyone know the problem here?

Theres no reason to pause and play the balls movement.
If you want some time for the player to be ready add an arbitrary countdown on reset. Typically you don't hard code movement values.
Its Y value on reset is typically a skewed random number, as is collisions.
Also post your "Collision".

well the y value could be a random number but i don't think it would change anything. and also, how would i not "hard code" movement while still having the ball move on its own from the start?

Appending a new element to a dynamically-resizing array has an amortized O(1) time complexity.

Is that still true if the item being appended is a string? Or will it have a time complexity of O(string length)?

>>61516462
just finished my new network stack (assembly, arm processors)

>>61519167
depends on the way the string is implemented. in c++ for example, a std::string looks pretty much like a std::vector under the hood so it would have the same complexity. But a null-terminated char* would probably work differently.

>>61519167
what precisely do you mean? give code examples

struct record* buff = (struct record*) malloc(n * sizeof (struct record));
if (buff == NULL) {
    perror("malloc");

}

pthread_cleanup_push(free, buff);

if (pthread_setspecific(key, buff) != 0) {
    perror("pthread_setspecific");
    exit(1);
}

According to malloc(3) manpage, calling free() multiple times yields undefined behaviour. How do I deal with this in code related?

>>61519167
If you are appending a string to a vector of strings, then the time complexity is O(string length) for copying the string or O(1) amortized for moving the string. If you are appending a string to a string, then it's just like appending multiple elements to a vector, assuming the string is implemented like a vector as in C++ and Rust.

OpenCV: BSD-licenced, 1,138 open issues. Just pick one, neet-o.

I bet you don't use/want to improve any GPL licensed software either, tard

Trying to optimise the liveness analysis code in my C compiler. Still takes 6-7x longer than clang on a particular pathological function with lots of instructions and virtual registers.

>>61520546
Modern Fortran isn't very interesting from the language perspective. Try Ada.

what is bitwise operators used for?

>>61520671
low level shit with bitmasks mainly

>>61520671
Left over from the days where we had to use every byte sparingly.

>>61520671
Still used a lot in embedded programming such as *duino

Can someone help me with >>>/biz/2855860? I need either an API or a data dump of intraday (minute level is ok) stock trading data.

>>61520671
Any time you need to operate on bits.
Basically any time you'd rather not waste space. Tons of people store boolean values to make up flags. But if you have less than 64 flags to store its way wiser to mask using a long int rather than using multiple bools.
It may seem picky but the performance impact of having big data where you don't need to is quite terrible. You'll stomp the L2 cache for no reason and waiting 200cycles to read 1 bit is just dumb. The situations where you early out om flags is the worst.
>but I work in languages like python
Then you don't have bitwise operations as a core of the language because it's pointless.

>can somebody gibsmestuff

lol

Is the space complexity of this algorithm O(1) or O(n + m), where n and m are the lengths of the strings passed?

function foo(strOne, strTwo) {
  // create arrays based on strings
  strOne = strOne.split('');
  strTwo = strTwo.split('');
}

I want to say that it's O(1). However, consider a language that passes by value rather than reference during the assignment of the arguments to the function parameters. Is that technically not linear space then?

>>61520975
The fuck are you talking about? I'm obviously going to pay for the data, no one is going to give you clean free intraday.

I don't want stuff, I just want some names.

Software is fucked because of brainlets like you who have no common sense.

C++ is the mess it is because it has tried to be everything with no clear focus. The things it does relatively well (RAII, Templates, STL) are still deeply flawed because they weren't really envisioned from the start and have bizarre limitations or gotchas because they were mainly just hacks.

No, C++ is fucked because the ISO refuse to break code you ignorant twat.

Can we all agree that Scheme is the most comfy language?

>>61521211
Those aren't mutually exclusive.

>>61521211
If the C++ standard broke code every time there was a major shift in focus there'd be a Python 2/3-tier split every 5 years.

>>61521220
They are though.

>dont break code
>all your additions are just stapled on and so your language is a mouse trap jungle.

>>61521229
plenty of modern languages now break code logically by adding @deprecated titles so people can transition ahead of time. Its really not a hard concept.

Sounds like hell to me.
