If I get bored later I'll find more links, but I know for a fact that several of the LISP ones are readily available online. Maybe have a go yourself?

and here is my code in response to
>>58393002

#include <stdio.h>
#include <cs50.h>

int main(void)
{
    int height;
    printf("What is the height of the pyramid?\n");
    height = get_int();
    
    do {
        printf("The pyramid cannot be higher than 23 feet!\n");
        printf("Try again!\n");
        printf("What is the height of the pyramid?\n");
        height = get_int(); }
    while (height > 23);
    
    if (height <= 23) {
        printf("The height of the pyramid is %d feet high!\n", height);
    }
}

So basically if I move

if (height <= 23) {
        printf("The height of the pyramid is %d feet high!\n", height);
    }

above

do {
        printf("The pyramid cannot be higher than 23 feet!\n");
        printf("Try again!\n");
        printf("What is the height of the pyramid?\n");
        height = get_int(); }
    while (height > 23);

It will say

>"What is the height of the pyramid?"
23
>"The height of the pyramid is 23 feet high!"
>"The pyramid cannot be higher than 23 feet!"
>"Try again!"
>"What is the height of the pyramid?"
*input here*

then it ends the program.

Ha! I've asserted there IS a job, and that you haven't done a good job. You've only asserted that you didn't do ANY job, which together agree with my point.

Now you're trying to claim that there isn't a job in the first place, which is:
1) Moving the goalposts
2) Pretty fucking stupid: if you're going to spam every one these threads with your shite, the idea that you don't care about the quality of said shite is laughable.

I decided I could make my first simple game so I wanted to make hangman which I will read words from a file and pick it randomly excepts I can't make it work.

FileInputStream in = new FileInputStream("words.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while((strLine=br.readLine())!= null){
String[] s = br.readLine().split(" ");
for(String index : s)
filearray.add(index);
}
in.close();

I get an error at "String[] s = br.readLine().split(" ");" which is pretty much reading the line in the file and splitting into words. I should just hang myself instead.

Hey, I want to learn C, should I got straight to K&R or are there better choices with less -posible- bad practices?

I was reading as well Modern C by Jens G. and didn't understood shit.

K&R C is great for writing ANSI C.

>>58395230
>split strLine instead of calling readline() again inside the loop.
I tried but "The method split(String) is undefined for the type BufferedReader".

Anyway, I already could make it work but I had to separate one word for each line instead of one line and spaces. I wanted to make it using spaces instead of lines.

>>58395326

Wat. strLine is a String. Did you try strLine.split(" ") ?

>>58395141
>split(" ");
shouldnt this be split(' ') //one apostrophe?

>>58395141
it may not be as nice, but try this

while(true)
{
var x = br.readline();
if(x == null) break;

//rest of code
}

I think in the second br.readline, it reads the next part. This could give an exception error the one in the while condition was the last one, and the assignment to s reads again but it goes out of bounds,

>>58395325
what should I read after finishing it?

>>58394902
Mine says 41

>>58395383

Probably not.

What split() expects is actually a regular expression pattern. It can be much more complicated than a single character.

>>58395457

You should read the source code to a few C programs you like to use.

dpt how hard would it be to make a collectivist village of programmers in usa?

>>58395457
You could try to go back to reading the book you didn't understand, because K&R C covers the language as a whol, yet wriiten in plain English.

I mean, it's really small scale, it usually works small scale. It's more a matter of wanting to be part of something. Cults have proven that it works fine. would work better without some demagogue exploiting it.

no, browser predates the API and the catalog by a few years. I've looked at the API but didn't see anything worth using.

If it's a commune, they'll all be hippies. People who wear striped thigh high socks are a dime a dozen in San Francisco. It's the gay capital of the world. As for Infrastructure... build it yourself, you damn commie!

Striped thigh-high socks are not just for the homosexuals, Ruby.

I'm pro-capitalism, hence not a fan of the hippie thing. It's more about having a group to grow with together within the greater capitalist system. And that's why I'm asking, how hard would that be? what would be the initial investment to establish something like that?

>>58395840
>I'm pro-capitalism
Prove it.

>>58395749
>less load on the servers
highly unlikely.
loading all of a board's OP thumbnails (which is also what the catalog does) currently consumes about 1.3MB on /g/. browser then refreshes the main index page every so often, which takes very little data since it's compressed html, and even less data when 304 Not Modified is returned.

I really doubt the API could consume less server resources than browser.

Then the proper question might be, "how do I make my own municipality." To which I say, take over an existing ghost town, clean the place up, get a bunch of Northern Californians to join you, and get an ISP in a nearby town to lay down some cable for you guys. And yeah, believe it or not, there are quite a few ghost towns in the US, abandoned for one reason or another.

the group would still be collectivist though. but you're right, maybe I should have phrased it like this just to get the right answers.

sure, optionally.
but it only downloads a thread when you request it (when the option is enabled and when you try scrolling to replies that browser hasn't seen yet). and it only downloads images on demand (right when it appears on the screen).

and regarding the threads, browser tries to obtain ALL new posts from the main index page. it does not load every thread.

#include <stdio.h>
#include <cs50.h>

int main(void)
{
    
    int height;
    do
    {
        height = get_int();
        
    }
    while (height >= 24);
    
    /*How many rows to print (how many times the height is printed) */
    for(int i = 0; i < height; i++) {
        printf("\n");
        
            for(int j = 0; j < height-i-1; j++) {
            printf(" ");
        }
            for(int k = 0; k < i+2; k++) {
            printf("#");
    }
    }
}

It works but I don't know how the fuck it works.

mainly this part

for(int i = 0; i < height; i++) {
        printf("\n");
        
            for(int j = 0; j < height-i-1; j++) {
            printf(" ");
        }
            for(int k = 0; k < i+2; k++) {
            printf("#");
    }
    }

Basically it outputs a "pyramid" based on the height.

The JSON can also be sent compressed and an API client can also send If-Modified-Since.

The API client also doesn't need the JS/CSS resources the browser does.

The difference is minimal but an API client does transfer less data(if written correctly).

>>58395988
to add to that, if browser is left running long enough, it can see ALL posts in ALL threads on a board simply by refreshing the main index page. this is especially true on a fast board like /b/, where the oldest thread might only be 6 hours old.

I've put tons of effort into making sure browser is a good citizen and doesn't rape the server.

Well let's put it this way: Most of the ghost towns in the US are ghost towns for a reason. They're old mining towns out in the desert and far from civilization. You would have the land, and some buildings, but you'd need to lay down pipes to get water from elsewhere, and cable to get Internet from elsewhere. You'd also need to get food delivered to you because nothing will grow there. When I said "clean the place up," that was a bit of an understatement. Everywhere worth living in is already being lived in, so you would have to take a shit town and make it worth living in. That on its own will detract most of the autistic "such a nerd" types, because they don't want to do real work. The problem, of course, is that since you want to fill your commune with programmers that all wear striped thigh high socks, the only type of people you will let in are autistic "such a nerd" types. Most of them will probably be SJWs too, since the idea of living in a commune only really appeals to SJWs.

So guys, I've finally decided on the core structure of my concatenative shell language.
I've decided to represent the two core structures (Syntax and Semantics) as monoids.
The evaluator is three lines, or six if you include the interpreter structure.
I'm pretty much set on what the syntax will be, although there is some ironing out to do with regard to system calls.
I'm currently writing a rough draft of the standard library, but I got distracting by reducing boilerplate, and I suspect I'm lumbering towards simulating variadic functions.

"Boohoo someone said fake news, they must be a SJW" how are you unaware of the absolute PLAGUE of fake news sites? There appears to be a significant portion of the population (like you, possibly) who browse with their critical thinking skills turned entirely off.

"Hurr dis banner looks high quality, must be a legit news site!"

Christ. You bunch of snotty dumbfucks.

As for the "sex attacks" nonsense, I first heard about this bullshit from the same retarded uncle. He sent me another "news" piece that cited some data about an insane increase in rapes in Sweden. It looked suspicious to me, like for the given number of immigrants they'd have to be raping full-time, 24/7/365 for the numbers to add up. So I googled it and, sure enough, the numbers were fabricated by a conservative "think tank".

Just like that "no go zones" bullshit, where they asked police if they'd ever felt unsafe anywhere, and turned that into, "police won't even enter these zones!" Absolute retardation. I honestly don't understand where the drive comes from for this sort of bizarre nonsense. Like, what's in it for you personally to be pushing this anti-migrant/anti-Muslim agenda? Does it just give you a justice hard-on, because you're too dumb to realize that you're reading false information?

Or do you actually think that you're somehow tapped into the truth, and the rest of the world just doesn't understand? Do you think you're saving us? Have you been evaluated for schizophrenia?

>>58398129
that's a really nice strawman, sören. but it's ok that there were over 2000 documented cases of rape in germany because niggers in the us rape at the same rate. isnt that great.

Some serialization/deserialization stuff for my game editor. I'm trying to keep the game's assets as text where it makes sense, to make debugging easier, and so that they produce nice diffs in git.

>>58398165
Niggers? Retard, most of the world has 10 rapes per 10 000

Democrat here. Pacific Northwest.
You're a fool if you think progressives aren't armed. Shit man a lot of us served. Those of us who haven't have family who have, family in law enforcement, and so on.
I've hunted and gutted deer. I've slaughtered squirrel in potato fields. I've fought. I've wrestled. I used to skate and I've broken so many bones I've literally lost count and walked half of them off.
And there's nothing special or exceptional about me.
You're a fool if you don't think progressives are formidable. For every straw man pic you have of a faggy liberal I have a pic of a fat virgin beta orbiter with a weak stance who still flinches when he fires.
I don't presume that the alt right is not formidable. I grew up surrounded by the tea party before they became the tea party. I know what they can do. I've hunted with them.
But that's what's funny about these neolibertarian pseudofascists. They assume they're the toughest guys in the world and everyone else is soft. That's why they keep losing wars.
The south loses. Every time they flex. Progressives are ruthless when cornered. We burned Atlanta to the ground and used rape as a weapon of mass psychological operation, disrupted troops and marched right up to Jefferson Davis front door. We designed a bomb that destroyed entire cities, then we upgraded it. We invented remote control flying guns and remote control bombers..
Don't fuck with us. The south will rise again? Fine. We'll put em down again.

>>58398163
things liberals disagree with or don't want to acknowledge == "fake news"

got it

>>58398157
Fuck optimisations, it's a shell.

>>58398129

Good job. These people are fucking retarded. Look at how desperately they cling to their bizarre, racist views.

Why don't these shithawks take their alt-right agenda and go somewhere else with it? I can't get a single tech question answered, but I've been inundated with xenophobic nonsense all day long.

>>58398040

I've been learning forth recently so I can try to work with an old f68hc11fn board. Certainly a different experience working with this kind of language. What made you decide to make one?

You anti-Trump, Cultural Marxist morons still don't fucking get it. This guy is the ANTI-Clinton, ANTI-Obama, ANTI-politic bullshit president. Obama would tweet shit like: "Happy New Year to a proud nation of diverse people and empowered women!" You know, Trudeau shit. This guy is making it clear: The days of peak cuck are over. If you stood in his way, he's going to fuck you over.

that's it. Im with her now.

any point you want to make?

>You're a fool if you think progressives aren't armed.

Wait, what? What the fuck are you talking about? Who said anything about 'progressives' not being armed?

Is this copy-pasta that I'm not getting, or did you reply to the wrong person, or are you just insane?

>>58398196
>things liberals disagree with or don't want to acknowledge == "fake news"

No, the vast number of fake news sites that make money on advertising by publishing LITERALLY FABRICATED 'NEWS' are fake news sites.

Seriously, are you guys not aware of this? It's been around for awhile, but it absolutely exploded during the election cycle.

Here's a podcast that looked into it and investigated a guy who makes a fair bit of money running several fake news sites:

I guess it's fine with you as long as it's only other people who get raped, huh? Then you can tell them to just, like, get over it and stop being so racist, he was from a different culture, he wasn't used to the effects of alcohol because of his religion, it was a sexual emergency, he's definitely a Syrian refugee despite not knowing any Arabic, or whatever the excuse of the week is.

For people who claim to care about women's rights you sure seem to throw them under the bus when a group of people you can virtue signal more for comes along.

Writing tests for any bullshit using gen_server behaviour is fucking painful, and nobody fucking does it. Either you have to wire up handle_call to just proxy shit to handle_info (which breaks shit) or you test everything else but the implementation, or, you be a dick and fire up the fucking thing with start_link and gen_tcp:send() in your tests.

>>58398216
You mean no more Eid tweets from @POTUS? Shit, what if we offend Muslims?

>>58398252
>I guess it's fine with you as long as it's only other people who get raped, huh?

Just makin' shit up right there.

I honestly have no idea what your point is. It was demonstrated that the claimed rape statistic was *wildly* inflated, and that the rape "plague" is on part with rape elsewhere.

If you want to prevent rape, mindless xenophobia isn't the way to do it.

>>58398252
now you baited to hard, friendo. maybe next time.

>>58398249
I am a Pozz-Cuckold. You want to know what that is? Well, let me explain.

The normal cuckold wants just one gift from his black bull: A black child. But the Pozz-cuckold wants more. He wants three gifts. We are greedy little bitches. But first, here's how it goes.

Normally I drive in my Mercedes to a street gym where ripped blacks train their muscles, there skin shining with sweat and the air filled with their scent. I am already a bit hard just from thinking about it. Sometimes I cum a bit in my pants. I get out of the car and ask who of them has AIDS. Then they know what happens.

The black man with AIDS gets into my car and we drive to somewhere isolated. Then I take a small knife and stick it inside the hole of my penis and twist it a litte. In the cuckold community we call this the AIDS twister. Sure it hurts and causes me to bleed. But it is worth it.

Then the black man docks me until we both cum and I contract his AIDS. I already have 4 types of AIDS from this. That is the first gift. Then we drive on to my house and he fucks my wife, who has also contracted many types of AIDS. That is the second gift. And then 9 months later the third and best gift arrives: a black child who also has AIDS.

Sounds a lot like the Guardian and CNN

Why is /dpt/ so shit when europosters are asleep?

>>58398291
because the americaposters are awake

>>58398280

Please do cite some articles CNN and the Guardian have published on fabricated events. Not simply getting some facts wrong, or covering one thing in favor of another. I'm talking about literally 100% fabricated stories.

>>58398270
Want to really reduce the number of rapes? Arm women, train them to defend themselves, and give them the right to do it with stand your ground laws and castle doctrine.

Gun control only serves to disempower women, due to the general strength disparity between men and women. Gun control is anti-feminist.

>>58398291
It's shit either way.

>>58398321
Try the whole fucking election. Try all the fake accusations thrown at Trump.

>>58398207
Couple of reasons, in descending order of importance:

1) They are incredibly clean and elegant, which are hand-wavy words that are vindicated somewhat here:
http://www.kevinalbrecht.com/code/joy-mirror/j02maf.html
2) Related to the above, they are very simple. This means I have fewer decisions to make (in contrast to LC-based languages where I start drowning in options). Furthermore, implementation is almost trivial, as demonstrated: all the time is spent in *design*, not actually implementing features/etc.
3) I haven't used a postfix language before, and a shell is a good place to try one out. Furthermore, I suspect the minimal syntax will help with terse commands (although, like all shells, I will require some nasty syntactic hacks to get it really terse).
4) Concatenative languages are closely tied to combinatory calculi, which I was reading about recently. I found this particularly interesting:
http://tunes.org/~iepos/joy.html
5) Because 'imperative' and 'functional' begin to overlap somewhat when you simplify down to the level of concatenative languages (demonstrated by Forth cf. Joy); I might take a crack at implementing a compiler later on, since I've never really had any experience of assembly.

>>58398214
I used finger trees instead of singly linked lists internally, are you happy now?


Is anyone else doing any actual programming?

>>58398077
so are you defining 'i' in that snippet?

>>58398364
Also note that I forgot that I was writing that list in descending order of importance.

Luckily it's pretty damn close, but point #4 should be tied with #1.

>>58398366
Not really. It's more 'what i does' than 'i the combinator', which I'm tempted to chuck in as 's k k' (fuck going fast, Ruby).

/**
 * Rotates the bits in a value left or right depending on ins
 * Params:
 *      *op1 is the value to be rotated and where the result is stored
 *      op2 is the amount to be rotated by
 **/
private void rot(string ins)(int *op1, int op2)
{
    int tmp = *op1;
    mixin("
    asm
    {
        mov EAX, tmp;
        mov ECX, op2[EBP];" ~
        ins ~ " EAX, CL;
        mov tmp, EAX;
    }
    ");
    *op1 = tmp;        
}

wtf I love mixins now

I'm finishing my algorithm for physically accurate 2d soft shadows that can bisect the light volume and create double edged occlusion from each occluder's segment.

Since it's the first of his kind (bisecting the light radius from 2 edges was not done yet) i'll publish full source once it's done

>>58398435
What's it written in?

>>58398364
>>58398366
>>58398393
I would also add that I think that all *sh derivatives are fucking abominable languages, and I'd love to be able to stop using them.
This is a strong motivator to actually complete this project to a usable degree, and not just come up with a design I'm happy with only to flake on implementing it.

>>58398451
Oh yes, I'm also pretty sure I can hack in lazy piping without too much trouble. That's another interesting problem.

In this game there is this store that sells an item X that expire at the end of the week and a player can buy things only once each time.At the end of the week the store resets and the item X can be bought again once and expire at the end of that week. How would you implement this? In a database would you just have one entry for item X and change the expire column? Or would you have multiple unique entries in the table for the item named X and the different weeks they expire?

Not homework just something that dumb devs of a game I play keep having problems with

>>58398450
It runs well on javascript + raw webgl, also the physics system is in pure js (matter.js)

But i'll soon port it to android with plain jni/c++ and box2d, did it in .js first for simplicity and to make a website out of it

If you could go back in time when you were in school or just learning how to program what would you tell yourself?

>>58398629
Don't try to do it right. Do it so it does what the client wants.

>>58398629
That I easily could have learned C/C++ when I was like 13, but I was too intimidated and only got enough courage at 17.

>>58398340

Citations. Come on, buddy, I'm not doing the work for you.

>>58398629
Do a maths degree instead

>>58398629
I'd tell my parents what to invest in, and when.

Why do people keep designing languages that are riddled with the mistakes of the past, like weak or dynamic typing, or OOP?

>>58398681
Then you are a liberal SJW feminist communist anti-white socialist cuck.

>>58398407

Nice.

>>58398364
http://tunes.org/~iepos/joy.html is always inspiring to read, really brings out the curiousity and elegence of the "hacker mindset", to me. Anyways, good luck.

How on earth did I convince myself that I'd actually get OpenGL working this time? Like, I actually fooled myself into believing I'd be able to successfully load a PNG image and render it on the screen.
