[b] [u][b]test[u][b] [u][o]test[/o][/u] !TRiPCoDE Why don't we talk about programming? It's a programming board! What programming board? I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called "Linux", and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called "Linux" distributions are really distributions of GNU/Linux.
HAHAHAHA
YOU THINK YOURE THOUGH UH ?
I HAVE ONE WORD FOR YOU
THE FORCED INDENTATION OF THE CODE
GET IT ?
I DONT THINK SO
YOU DONT KNOW ABOUT MY OTHER CAR I GUESS ?
ITS A CDR
AND IS PRONOUNCED ``CUDDER''
OK YOU FUQIN ANGERED AN EXPERT PROGRAMMER
THIS IS /prog/
YOU ARE ALLOWED TO POST HERE ONLY IF YOU HAVE ACHIEVED SATORI
PROGRAMMING IS ALL ABOUT ``ABSTRACT BULLSHITE'' THAT YOU WILL NEVER COMPREHEND
I HAVE READ SICP
IF ITS NOT DONE YOU HAVE TO
TOO BAD RUBY ON RAILS IS SLOW AS FUCKBBCODEAND ((SCHEME)) ARE THE ULTIMATE LANGUAGES
ALSO
WELCOME TO /prog/

When I use an editor, I don't want eight extra KILOBYTES of
worthless help screens and
cursor positioning code! I just want an
EDitor!!
Not a "
viitor".
Not a "

WORDS!!!!
ED!
ED!
ED IS THE STANDARD!!!
1. Use fprintf ("fast printf") instead of printf.
2. ++i is faster than both i++ and i = i + 1.
3. void main(void) is faster than int main(void) or int main(int, char **) since no value needs to be returned to the OS.
4. Swapping with exclusive-or (a^=b^=a^=b swaps a and b) is faster than using a temporary. This works for all types (including structures), but not on all compilers. Some compilers may also give you a harmless warning.
5. Static storage duration objects are faster than automatic storage duration objects because the CPU doesn't have to set aside storage on the stack every time a function is called. Make your loop indexes global so that you can use them everywhere:
int i;
void func(void) { for (i = 0; i < 10; i++) ; /* ... */ }
void func2(void) { for (i = 0; i < 20; i++) ; /* ... */ }
/* ... */
6. Compilers often give more memory to arrays than you asked for. Here's how to check how big an array actually is (memset returns a null pointer if the size you passed to it is bigger than the size of the array you passed to it):
int arr[256];
size_t realsize;
for (realsize = 0; realsize <= SIZE_MAX; ++realsize)
if (!memset(arr, 0, realsize)) break;
/* now you know that arr actually has realsize / sizeof (int) elements */
If you combine this with #5, your program will be faster in the long run (but this usually doesn't work for short programs).
