Programming?

[Skridovaste 11]

#include <pthread.h>

#include <unistd.h>

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

#include "user.h"

void *worker(void *arg){

while(1){

if(((user_t*)arg)->sux){

printf("&ssux\n", ((user_t*)arg)->name);

break;

}

}

}

int main(int argc, char **argv){

pthread_t **threads=malloc(sizeof(pthread_t *)*(argc-1));

void **output=malloc(sizeof(void *)*(argc-1));

int i=1;

for(;i<(argc);i++){

pthread_create(&(threads[i-1]), NULL, worker, findUser(argv));

}

int j=0;

for(;j<(argc-1);j++){

pthread_join(threads[j], (void**)&(output[j]));

}

}

What is that? What language is it even?

its a multithreaded joke that got out of hand

also its C

think of parallel programming as the thing that lets your computer run multiple applications at the same time, efficiently

also there was indenting but it got ruined after i posted

oh shit wait i forgot to free the memory i allocated at the end and now there is memory leaks i am a FOOL

I know I probably should know this already, but what kind of things can Python do? I know it is more of a scripting language then a programming language, so what sort of scripts can it write?

Python's used pretty extensively for web development (Django is the most popular of its web development frameworks I think). Most notably, Google uses Python for lots of things (also Yahoo and Youtube), which is a big reason for why it started gaining popularity. BitTorrent was written in Python up to its 6.0 release. Apparently Civilization IV uses Python for its inner logic including AI, and Battlefield 2 uses it for all of its addons and things like score keeping (hi wikipedia).

So it's pretty common deal to write something up in Python, then reprogram certain parts where performance is critical in a language like C++, or to use python as an ADHESIVE for parts that need to be easy to maintain

I don't know much about Lua, but it's like the most popular scripting language in games and has a reputation for being fast

updated it using code BBC tag to make it readable.

did not add the freeing memory part to remind me of my mistake FOREVER

[T1g 1503]

this is all I really know about python

[Ganny 285]

That's all you need to know

typing "import antigravity" in the Python interpreter brings up that page, also

Next MP we are doing is MapReduce

holy shit this is the best April Fools joke ever

learn it in a college who's strongest department is computer science

elitist

can't even spell whose right

Java is a bad idea to learn as a first language. It's conventions are rather different from a lot of other languages, and its overreliance on classes can make learning other languages after Java confusing.

This is absolutely true. Watch out!

i noticed that the more advanced programming techniques i learn

the more typos i make

soon i will make all of my posts in c format

[Ganny 285]

I don't think "who's" is valid C

BAADDA BOOOM BBABAAAAAAA

while(1) printf("gannysux ");

so i finished MapReduce the day after I got it so I dont have homework in that class for 2 weeks

basically, MapReduce was created due to parallelization.

So, Imagine I have a huge text file, or some other form of data. I want to Find out how much a certain piece of data occurs in the file (like a word). You could do a linear O(n) run through the whole file and count it up that way, OR you could use parallelization to divide the file up into smaller files, and have each one of those get scanned through at the same time.

MapReduce is for this situation right here:

imagine i want to count the number of each letter in "Hello World"

After parallelization, you get

H 1 E 1 L 2 O 1

W 1 O 1 R 1 L 1 D 1

but you need to combine these two lists, both of which contain L's and O's. So that its

H 1 E 1 L 3 O 2 W 1 R 1 D 1

this is a really simple explanation but a good one

our last assignment is going to be implementing a web server

idk if I will be able to link you guys to it but I will certainly try
