What are you working on, /g/?
first for rust is shit
PHP IS BEST LANGUAGE
third for go is shit
Java
xth for D sucks ass
nth for static typing
>>51710888

nth for homotopy type theory and higher inductive types
I figured out how to split screens and switch between them using screen, but I can't get anything to type in the second screen. Pls halp. Also if there is a better alternative in vim that would be great.
Basically I want terminal/vim to behave like the instructor's gedit does

Currently working on coding new firmware for a new type of delophonic verbirator that will be built at work for hydro electric power variable integration in the next six months. Because shit needs to be cross platform (major drag), it written in Racket. (Not many Racket hackers in Australia in this kind of work.)
any idea why this makes two leaves, their parent node, and then segfaults?Node* treeFromBinary(BFILE* filename)
{
if(readBit(filename)==1)
{
Node* leaf = new Node(readByte(filename));
return leaf;
}
else if(readBit(filename)==0)
{
Node *left = treeFromBinary(filename);
Node *right = treeFromBinary(filename);
Node *nonleaf = new Node(left, right);
return nonleaf;
}
else
{
printf("end of file\n");
return NULL;
}
}

There are many variables that concern hydro power.
(After all we are dealing with nature here).
Variables, (such as rainfall etc), need to be entered into the firmware so the machinery can deal with complex changes according to whats happening with the environment. Thats all.
Why would one Ruby gem give me fail to build native extension errors on 7 ("gem install twitter" for example) but a different one install fine (nokogiri). I've been trying to fix this for like 5 hours with zero progress..

Pretty much no ruby dev ever tests this shit on Windows.
That said, ffi gems under OSX is currently fucked.
I had an idea for an actual prototypal language, allowing you to create classes that add functionality to any type of object (as long as it satisfies some parameters) but is strongly typed.
This would be used to create small component classes to build up a larger object, which is all the rage right now in gamedev.

m8, this guy didn't know basic trigonometry like a couple of weeks ago and his physics are still messed up. just learn a bit at a time and it will all come together
>>51711954
Could definitely just be C. I think those are default GLUT menus.
>>51712026
I began learning C a couple weeks ago. It's not hard, it's just graphics are intimidating to the new programmer.
>>51711986
not sure if i'm even allowed to post this pic but this is what the foam is used for...
>>51712047
Just C and GLUT.
>>51712045
>>51712051
Also the physics are fucked up, yeah. I'm working on a tiny scale so I'm not using actual gravity, and there's no angles involved so things like angular momentum aren't here.
It's just gravity, friction, air resistance, inter-particle collision, particle-floor collision. Particle collision is jank, though.

Word Sudoku.

>>51712173
What are the rules? How is it different from normal Sudoku?
>>51710874
Does this seem like the most efficient algorithm for finding the divisors of a number n?
1. generate all primes under n/2 with a sieve
2. use primes to factor n into a list of divisors and their respective powers
3. permute all possible powers for the divisors and take their total products to find a divisor of the number
100 = [(5 2), (2 2)] // that is 5^2 * 2^2
permutations for powers
5 2
-----
0 0 = 5^0 * 2^0 = 1
0 1 = 5^0 * 2^1 = 2
0 2 = 4
1 0 = 5
1 1 = 10
1 2 = 20
2 0 = 25
2 1 = 50
2 2 = 100
I'd think, especially for large n, this would be much faster than trial division. Yes or no?
>>51712185
Cyan = unbounced
Yellow = bounced
Magenta = can no longer bounce
Magenta is for particles below the lowest floor (killplane) or ones with no speed.
>>51712168
It's not done yet.
>>51712173
yellow's really bright, good for the selector but not the borders
actually make the selector a bit more noticeable
and darken the yellow so that the letters are more prominent
what are you making it with?
>>51712186
I have no problem with being a furry in and of itself. 99% of furries are disgusting, but I wouldn't mind being friends with a non-disgusting furry.
My own interests (weebshit) are hardly respected, so I won't judge other people for their interests.
>>51712205
>It's not done yet.
And? It will probably never be done.
>>51712230
I have a list of things I want to implement. It's done when I hit them all.
>>51712237
OK, good for you.
Can we see the code in the meantime?
>>51712196
Exactly the same as Sudoku, but with words. In this case it's a 9 lettered word.

Thanks man. Java. I know very little programming so I'm teaching myself the basics with this
anyone know how to cast the struct stat variables to stuff from INODEs and MINODES?
struct stat statistics
printf("gid: %u", &mip->INODE.i_uid);
statistics.st_mode = ip->i_mode;
statistics.st_mode = ip->i_mode;
printf("gid: %u", statistics.st_mode);
mip is a MINODE pointer that is in the correct directory and ip is an INODE pointer that is correct as well.
I just don't understand how the fuck to cast struct stat correctly.
I see people making it a pointer but that failed for me too. Anyone got ideas? my head is kind of in a fog right now.
>>51712259
Sure, here's a code snippet:#include <stdlib.h>
#include <stdio.h>
#include <malloc.h>
#include <freeglut.h>
#include <math.h>
#include <stdbool.h>

Some people started programming just because they want to make games, and they are all faggots.
Games can be hard to make from scratch, though, depending on how scratch and how complicated the game.
>>51712706
games deal with algorithms and performance constraints that most programmers never have to deal with. Plus it can be fun and challenging.

In c++, how can I use erase() to remove all of the semicolons from a string?
>>51712932
(some) dogs are retarded
>>51712953
you probably wouldn't use string::erase. or c++.
But in all seriousness, you would find the index of the ';' and erase if if you really needed to.
>>51713021
It's for an assignment and I'm not really sure how to remove a character from a string without evaluating every character. Is there a simpler way?
>>51712932
If you're programming literate, can you please answer my question?

Why don't we see more second amendment advocates pushing to own nuclear weapons?
If they extend their philosophy to its logical conclusion then citizens of the United States should be able to own any and all weapons, including those that can kill thousands of people in one go.
Is it so ridiculous a concept that most gun rights advocates aren't interested in touching it, or do they actually have a personal limit set(in terms of a weapon being too dangerous or deadly) on their gun liberty philosophies due to morality, feasibility, or economical reasons?
If the whole point of the second amendment is to guarantee the right to bear arms in case the higher-ups need to be forced out of office then you would imagine that it should extend to things that could actually destabilize the country in its modern form. The fact is that even a large group of men with the worst guns possible can't do squat against America's fearsome military. The only thing that poses such an existential threat that it could alter the nature of our government are WMDs that can destabilize large portions of the country. If gun advocates truly cared about protecting the second amendment, why don't they want to keep it as modern and relevant as possible? Why not claim that WMDs should be included in the right to bear arms? If they think the second amendment should extend to the insane killing machines that are modern assault weapons, which the writers of that amendment could have never imagined, then shouldn't they extend out to anything with massive killing power? It's just weird that they seem so gung-ho about their rights even though there's such an obvious disconnect between the logic of the amendment and the common sense reality of futility against the government.

Sounds like youre struggling with architecture. If something is implemented in am extended staye, expect the thing to have it's own class and expect every other step in the parent object to have a class as well.
Like...if its a factory every operatable "machine"/"cog"/thing will have a class that you can specify action to or from where to gather info. Just like the internet has an OSI model that layers a packaging process over several steps and each one deals with the info in a manner distinct from the rest.
Another good way to see it is that your keyboard has a board, chips, gates and then ultimately a "parser" that then transfers the info from one form to another and then the packaging process happens again. Gotta make jobs for all these useless people somehow.

i am using c. when i run my compiled software in my terminal (i am just using the default xfce4 terminal) the output is placed before my username@hostname. getchar() isn't working. what can I do to fix this?
also what is the purpose of return 0;? the website i am using (cprogramming.com) says it is for error checking. but when i don't write return 0; nothing seems to be different at all

>the latency of trying to talk to a server-side application to make a move in games like Tetris means you need to do things client-side.
>implying
Here's a very rough estimation:
>50ms latency
>100ms to send/receive data
>10ms for the actual computing (probably much much less)
You could easily fit 6 moves per second. That's enough not only for tetris but for a many many other games.

Quadratic residues.
x^2 mod p (where p is prime)
will generate a unique sequence of numbers as long as 2x < p
for 32 bit numbers pick the closest prime to 2^32, it wont fit exactly so the rest of the numbers you can just identity map.
Then combine this with other bijective functions and you have a PRNG that generates a unique sequence.

That's fucking awful for tetris you retard. Try playing tetris with 100ms input lag and see how much "fun" it is.
4chan might not be the best place to ask this, but I'm writing a scraper for a website whose admins have openly expressed their dislike of data scraping.
Yes I know this is legally risky, however they don't really have a browserwrap agreement and the data is available without registering/signing up and agreeing to any TOS, so I figure I'm okay to archive the data for personal use. It's also indexed on google.
I understand that I should rate limit and try to make my user agents look as common as possible.
What else can I do that ISN'T distributed?

xorshift does not generate a guaranteed unique sequence (since it's generally a bad attribute for an RNG)
>>51715421
you don't do server sided calculations when you don't have to
there is no point
the point of a game server is to broadcast messages to other players, store essential state and store any game state needed to validate the correctness of received data so the server doesn't just forward bullshit moves
sometimes, when the server already has to do some heavy calculation as a result of one of the reasons mentioned before, it makes sense to just notify clients from the server so they don't have to calculate it themselves
in a single player tetris, none of these reasons is fulfilled, so there is no point in doing any server sided calculations

That's my thinking, but there's always stories like this http://petewarden.com/2010/04/05/how-i-got-sued-by-facebook/ that make scraping seem fairly precarious.

You must have been using shit documentation/tutorials, 2 weeks ago I started learning OpenGL and in about 8 hours I had a semi-working game base with texture and model loaders, basic player camera, simple collision check (albeit flawed) and font rendering.

I don't know anything about NUMA.
Assembly won't really help you to write cache-friendly stuff, it'll just let you check to make sure that the compiler isn't shuffling things around and messing with what you're doing at the C level. Cache optimization is pretty simple, you just want to minimize the amount of non-serial memory access. Pointer chasing is bad, virtual functions are bad, making structs have too many fields that don't get used together so you can't load as much useful stuff in a cache line is bad, etc.

hey guys i'm trying to make a compression algorithm which uses a huffman tree to compress on a character-basis.
right now i'm just trying to print the encoded tree to a text file, and then read it in with another program and convert it back to a tree within that program. i'm running in to trouble. some of my character codes are 9 bits, but my professor's binary functions are as followsvoid writeByte(BFILE* f, int b)
{
int r = b;
if(r < 0) r = r + 256;
for(int i = 0; i < 8; i++)
{
putc((r >> 7) + '0', f->file);
r = (r << 1) & 0xFF;
}
}
for writing a character's code andint readByte(BFILE* f)
{
int r = 0;
int b;
for(int i = 0; i < 8; i++)
{
b = readBit(f);
if(b == EOF) return EOF;
r = (r << 1) | b;
}
return r;
}
for reading it.

any insight on where i may be going wrong would be helpful. i spent last night trying to see if there was an issue with the uncompressor program's side, but i couldn't find any, so i figured it must be on the compressor's side.

writeByte and readByte are both my professor's functions. there's also thisvoid writeBit(BFILE* f, int b)
{
if(b < 0 || b > 1)
{
printf("Bad bit %i passed to writeBit\n", b);
fflush(stdout);
}
putc(b + '0', f->file);
}
and thisfor reading an individual bit (1 is supposed to indicate a leaf which holds a character, 0 is supposed to indivate a nonleaf which holds a left and right node pointer)
int readBit(BFILE* f)
{
int c = getc(f->file);
if(c == EOF) return EOF;
else return c - '0';
}
>>51718490
what the shit is BFILE?
>fflush(stdout);
The standard does not allow this
>>51718508
this is the rest of the binary file he gave us#include <cstdio>
#include "binary.h"
using namespace std;
struct BFILE
{
FILE* file;
BFILE(FILE* f)
{
file = f;
}
};
BFILE* openBinaryFileWrite(const char* filename)
{
FILE* f = fopen(filename, "w");
if(f == NULL) return NULL;
else return new BFILE(f);
}
void closeBinaryFileWrite(BFILE*& f)
{
if(f != NULL)
{
fclose(f->file);
delete f;
f = NULL;
}
}
BFILE* openBinaryFileRead(const char* filename)
{
FILE* f = fopen(filename, "r");
if(f == NULL) return NULL;

}
void closeBinaryFileRead(BFILE*& f)
{
if(f != NULL)
{
fclose(f->file);
delete f;
f = NULL;
}
}
it's not actually a binary file, it just prints text in 1's and 0's to make it readable so we can debug it if needed. there's a separate file we're supposed to replace it with at the end with a different implementation that actually does it in binary
