What's the meaning of exception code “EXC_I386_GPFLT”?
...lem is without more context, there are 27 different causes listed in my AMD64 Programmer's Manual, Vol 2 from 2005 - by all accounts, it is likely that 8 years later would have added a few more.
If it is a 64-bit system, a plausible scenario is that your code is using a "non-canonical pointer" - m...
Why isn't sizeof for a struct equal to the sum of sizeof of each member?
...'s an example using typical settings for an x86 processor (all used 32 and 64 bit modes):
struct X
{
short s; /* 2 bytes */
/* 2 padding bytes */
int i; /* 4 bytes */
char c; /* 1 byte */
/* 3 padding bytes */
};
struct Y
{
int i; /* 4 bytes */

What is the size of an enum in C?
I'm creating a set of enum values, but I need each enum value to be 64 bits wide. If I recall correctly, an enum is generally the same size as an int; but I thought I read somewhere that (at least in GCC) the compiler can make the enum any width they need to be to hold their values. So, is it possib...
Is there a Unix utility to prepend timestamps to stdin?
...row this out there: there are a pair of utilities in daemontools called tai64n and tai64nlocal that are made for prepending timestamps to log messages.
Example:
cat file | tai64n | tai64nlocal
JavaScript/jQuery to download file via POST with JSON data

Meaning of epsilon argument of assertEquals for double values
...or (say for degrees) you could set epsilon to 1 meaning that, for example, 64.2° is the same as 64.8° (since abs(64.8-64.2) < 1)
