old thread: >>52107255
What are you working on, /g/?
Posted in last thread.
How do I motivate myself to learn a programming language? I did some C in college last year but haven't touched anything since. What do I do?
Threadly reminder that coding is not the proper term to use when referring to the act of programming
You are a programmer not a coder
While programming you produce code
>>52111886
Before the bump limit.
REEEEEEEEEEEEEE
Based trap threads
>>52111903

Daily reminder that if you are this autistic, you are not cut out for life
>>52111936
Then fucking post yours already
>>52111908
While programming you should produce programs. If you can only produce code you might as well kill yourself now and end your suffering.
>>52111903
I'll rephrase this actually.
I absolutely loved the module, came out top of my class in terms of grades too. But how do I continue? Should I continue learning C or try and learn some scripting language like Python?
>>52111946
sure thing redditor
What CSS does /dpt/ recommend for 4chan?

I would like to move replies to the bottom of posts next.

kill yourself
>>52111909
you better get used to posting them around 290-300. the de facto standard is to keep the thread posted near the bump limit and delete subsequent threads as they are to be considered duplicates. the only way to reduce the occurence of trap threads is to post early threads of your own. i would have posted a thread myself if it weren't for the fact that i'm going to bed now. have fun :^)

Fuck off, brodowner.
>>52112011
they produce code. they don't make programs. they make markup shit and simple scripts. they are neither professional nor hobbyist programmers.
>>52111968
This is a dumb question. If you have an interested in C, continue with C. If you have an interest in Python, do Python. If you want to learn a programming language to get a job, read some job offerings to see what they want.

Making your stack a linked list means no stack overflows unless you run out of memory.typedef struct _frame {
int data;
struct _frame *next;
} frame_t;
typedef struct _stack {
struct _frame *head;
unsigned size;
} stack_t;
void stack_push(stack_t *stk, int data)
{
frame_t *frame = (frame_t *) malloc(sizeof(frame_t));
frame->data = data;
frame->next = stk->head;
stk->head = frame;
stk->size += 1;
}
int stack_pop(stack_t *stk)
{
if (stk->head == NULL)
printf("Stack empty.\n");
frame_t *frame = stk->head;
int data = frame->data;
stk->head = frame->next;
stk->size -= 1;
free(frame);
return data;
}
>>52112080
Oh right, I did feel the difference
c++
what is the difference betweenstruct
{
string text1 = "foo";
string text2 = "fooo";
}foo;
andstruct foo
{
string text1 = "foo";
string text2 = "fooo";
};

Why is /dpt/ still called /dpt/ if it isn't actually daily?
The old thread is less than 5 hours old.
>>52112077
wow dude u r right i have been lookin at this world wrongly this whole time!!! guess i need 2 do more codin...
>>52112102
I like that stack_pop checks for NULL and then just proceeds to use it anyways.
>>52112102
Have you ever heard of vectors?
>>52112134
not sure if pretending or seriously assburger
>>52112047
I don't care about any language in particular, that's why I'm asking. I have no idea where to start so I can just start learning about programming instead of start learning language x or y.
>>52112140
This is literally a vector if you keep traversing stk->head->next->next.... and so forth
>>52112117
>>52112117
first one just declares a "foo" variable that has a text1 and text 2 variable as its structure
second one declares a reusable type. Not a variable. which allows you to later go on and declare instance of the "foo" type likefoo fooins;
foo fooins2
>>52112130
/dpt/ stands for /dog petting thread/
>>52112102
Oh.
You meant a stack implemented as a linked list.
I thought you were referring to the other way around.
>>52112140
Vectors aren't thread safe.

Daily implies like a regular, ongoing thing, like your life.
Your daily chores are called "daily" even if you don't do them daily.
>>52112172
Do a project you actually care about and preferably with others.

unless you have the right text so that it will align perfectly at the intersections, it's inevitable for one text to go "on top" of the other(s)

His implementation of the stack isn't thread safe, but the initial post was about multithreaded stacks implemented as linked lists.
Incidentally, multithreaded queues ARE implemented as linked lists.

Shut up cuck, you have your flaws too.
>>52112266
He's being sarcastic.
>>52112244
if you use for example bresenham's circle drawing algorithm, the circles will not align correctly at the intersections because of the geometry of the flower of life.
>>52112266
Depends, where do you draw the line?
>>52112288
People who are or were wards of the state because of their illness sound like a pretty good generic line to me, though I'm not him.
>>52112281
Weird, perfect circles line up properly on paper.
>>52112253
>Incidentally, multithreaded queues ARE implemented as linked lists.
Yeah, that makes sense.
If anon wanted to make thread-safe code all he would have to do is add a mutex. Or if he really wanted to travel down the rabbit hole a lock-less list is the simplest lock-less ADT to make.
>>52112314
yes but now you have "pixels" in the form of a grid of chars. you can't draw perfect circles like this.
Do you professional programmers do a lot of stuff on the side?
Some days I have that itch to solve shit, others I want to kill myself if I look at a screen some more.
>>52112326
Well maybe your circles aren't big enough.
>>52112277

Oh, I'm sorry. I was giving you the benefit of the doubt, I didn't know you were actually retarded.
Dumb question, which I don't know how to search for on google:
Is there a file extension that defaults to opening a file in the web browser, as an URL?
>>52112288
I'm not sure, but I would assume there are people out there who definitely aren't fit to own guns (i.e. most republicans). Arming everyone seems careless.
>>52112373
>I didn't know you were actually retarded.
Praise the lord and pass the ammunition.
>>52112345
making them larger would indeed improve their appearance, or in the case of bresenham circles improve the approximation of the flower of life. but i would have to piece together several screenshots or concoct the image in some other way and i can't be bothered doing that right now. good night, for real this time
Haven't been to this thread in years. What do you guys who program games use (discounting raw sepples+opengl and SDL). Love still can't target web afaik, but snowkit's too immature. Maybe I should stop being lazy and do shit in javascript
>>52112345
That's part of the problem. If he drew them in terms of actual pixels (SDL/SFML, Graphics/C#, Graphics2D/Java, etc) he'd have circles which were a lot more accurate.
>>52112402
raw sepples+opengl

Opinion discarded.
>>52112382
.htm
.html
possibly .url
maybe more, don't know
>>52112413
yes but you fuck up the flower of life pattern because the circles are supposed to be a certain distance and angle away from each other
>>52112387
This is the greatest irony to me. Republicans are the front runners for gun ownership yet most of them are unstable old codgers who should never be allowed near a gun.
>>52112422now you're getting it
>>52112435
More accurate circles would result in a more accurate flower of life.
>>52112435
wait nvm i see you're talking about actual pixels. indeed with a higher resolution y'all niggas wouldn't be so upset about the circles
>>52112428
>Gun grabbers pls go
Sorry, but gun ownership should only be allowed for people who can trace their ancestry back 5 generations or more.
>>52112428

Last ludum dare I followed was the one where chrome deprecated extensions and everyone panicked. At that time, prevailing opinion seemed to be that unity's HTML5 export was shit. Has it gotten substantially better in the past year or so?
>>52112486
>At that time, prevailing opinion seemed to be that unity's HTML5 export was shit.
everything about unity is shit
>>52112102
Implementing a stack as a vector also means no overflows unless you run out of memory.
>>52112195
>I believe private weapon companies should be free to sell weapons to enemies of the state
No. As a general rule of thumb, aiding someone whom you know to be committing a criminal act is, in and of itself, a criminal act. Aiding someone who has declared war against your people is treason. The proper role of government is to protect the people's rights to life, liberty, and property. Part of this role requires maintaining an active military, and may even require an offensive role against groups that have attacked us in the past.
>I believe there should be no public roads or property
The constitution actually has clauses for public roads and property. If we consider that the government must protect the people's rights, sometimes via a military, this logically requires an infrastructure to support said military. How do you move tanks and troops around a country without roads?
>I believe the mentally ill should have easy access to recreational drugs
Yes.

Kewl. Enjoy programming in Lua where typos create a new variable that's initialised as nil then.

Has anyone every reverse engineered a USB device protocol to get data off of it? It's basically an RFID reader but doesn't simulate keypresses - it keeps the data on the device until it gets some command and then sends it over.

hey /dpt/
how much of your time spent "programming" is on average spent thinking/working through the problem you're trying to solve rather than actually physically entering code?

There are already kernels written in Haskell. House comes to mind but I think there are plenty more. Haskell isn't an ideal systems programming language due to the arcane ghc knowledge you need to be able to predict how memory will be used. Rust is the language you should be using.

Trannies and SJW types have literally contributed nothing but shitposting to any project ever. It's an extreme form of bikeshedding - they can't contribute shit to real discussions so they make themselves into victims in order to get the attention they can't legitimately earn.
I honestly don't think I've ever seen these people write a single line of code. They just chase away real developers then claim the remnants of projects as their own work since they're the only ones still around.
At what point should I make a GitHub? I haven't made anything original, just uni assignments and stuff out of textbooks.

Are there any image file types that are easy to digest? I'm thinking of making animation/motion graphics software out of frustration and I'd like to output a sequence of images.

there was this guy in an intro programming class that wanted to write a program that read a text files of number pairs (frequency, duration) and played the sound
ended up using some strange library that needed borland C in an MSDOS vm or something like that.
>>52116681
There are plenty of libraries that handle that for you. No image format is easy to work with. not even BMP - most BMP pics are easy to process, but there is some insane shit in the standard and implementing it all is more difficult than implementing PNG from scratch.
>>52116723
Although I'll add that if you're only interested in outputting images and not reading them, BMP is the easiest way to go without having to rely on third party libraries.

Does the C standard guarantee the size of a bool to be one byte?

If so, why are we using chars as bytes?

OpenGL + GLFW.
>>52117328
A byte is the smallest addressable unit of memory.
If you wanna play with individual bits, you have to dedicate at least 1 byte to a bitfield.
If you make a bitfield that only uses 1 bit, the rest of the bits will be padded out.
I'm pretty sure the _bool type in C takes up the size of an integer on the platform it's running on.
>>52117328
Quickly glacing at the standard, it seems that it is possible for _Bool to be larger than a char, but I don't believe that any sane implementation would do this.

There, much more efficient.
>>52117542
I'm pretty sure operations on those fields are going to be way, way less efficient.
>>52117559
Hardly. Maybe you'll need an extra instruction to access it, but it would hardly be bad.
It's better that wasting 7/8 of the memory used.
>>52117586
> you'll need an extra instruction to access it
That's already less efficient!
Modern superscalar architecture can parallelize your work involving a b c, but if you put them all into one byte, it won't.
>>52117542
You're using 3 bits out of a bitfield.
That's pretty wasteful desu.
>>52117596
If I was allocating a shitload of those, I would still go for the bitfield. It would remove a lot of wastage and means that you could fit more into a cache line.
>>52117633
I guess we won't know unless we test it but I still think it will be faster to do one byte per one bool.
>>52117657
C++ does some interesting optimizations, not this situations but similar:
https://stackoverflow.com/questions/29656648/java-8-times-faster-with-arrays-than-stdvector-in-c-what-did-i-do-wrong
Bitshifting does cost something and arrays already get good cache performance. As with anything it's a tradeoff but I'd argue until you have benchmarks telling you otherwise byte packing is usually a bad idea.
