C dynamically growing array
I have a program that reads a "raw" list of in-game entities, and I intend to make an array holding an index number (int) of an indeterminate number of entities, for processing various things. I would like to avoid using too much memory or CPU for keeping such indexes... A quick and dirty solution I use so far is to declare, in the main...

Erlang - C and Erlang
I am building a program that mainly parses binary data and does some number crunching on it. It's primary goal is to do it all as quickly as possible. It will be running on an 8 - 32 core machine [Xeon / Sparc T2]. I choose erlang becasue I beleive that concurrency is much easier as opposed to c++. However, about halfway through I start...

If-else problem
I'm learning queues and I came across this piece of code. It's from a book, so I can't post the whole code here but what I'm posting will be sufficient. More than a problem, I just want to confirm that whether my understanding of this code is correct or not. In the function, delete_ap(), the 'if' statement calls qretrieve() function and...
fscanf: reading a ',' instead of '\n'
Hello everyone, i'm reading a file which contains data such as this: 1,1 0.5,0.5 2,2 these are vectors, all numbers are double. since in my exercise the length of each vector is known, i'm using a for loop to read each vector: for (i=0; i<NUM; i++) { //number of vectors to read for (j=0; j<DIM; j++) { //length of each...

VIM open compile error in existing or new tab
When I compile or run a file from VIM all error references are opened in the last active buffer regardless if the file is open already in another vim tab. This behavior is very annoying. Is there any way to force vim to behave like ':tab drop' on compile errors? (See http://vim.wikia.com/wiki/Edit_a_file_or_jump_to_it_if_already_open) ...

I have this algorithm that I found here, just one thing puzzles me about it: Clear the stencil buffer to 1.
