What do 'real', 'user' and 'sys' mean in the output of time(1)?
...h a secure mechanism and both processes have to explicitly attach to it in order to use it.
The privileged mode is usually referred to as 'kernel' mode because the kernel is executed by the CPU running in this mode. In order to switch to kernel mode you have to issue a specific instruction (often ...
What are the differences between virtual memory and physical memory?
...s you from the realm of caches and RAM to that of disk, which is slower by orders of magnitudes. Painfully, irrevocably, transcendentally slower. It is an I/O operation, which means it is not CPU bound (it is rather the exact opposite), which means it does not need to occupy RAM right now. However, ...
Fastest way to check if string contains only digits
... testing (always profile because the results depend on hardware, versions, order, etc.):
static bool isDigitsFr(string s) { if (s == null || s == "") return false; for (int i = 0; i < s.Length; i++) if (s[i] < '0' || s[i] > '9') return false; return true; }
static bool isDigitsFu(string s)...

...ty issue (see: preload attack). This behavior is similar to library search order in Windows (before it had been hardened recently). It's a pity that Python does not follow the trend and does not offer a simple way to disable adding . to sys.path

abort, terminate or exit?
...t successfully exits the
application, and calls atexit()
functions in LIFO order. I don't
normally see this in C++
applications, however, I do see it in
many unix based applications where it
sends an exit code at the end.
Usually a exit(0) indicates a
successful run of the application.

How did this person code “Hello World” with Microsoft Paint?
...olor data (for 24 bpp images it's 3 bytes per pixel, stored in reverse row order and with 4 bytes row stride).
The bytes for color data are used to represent colors (i.e. none of them are "mandated" by the file format2, they all come from the color of each pixel), and there's a perfect 1:1 correspo...
Is MD5 still good enough to uniquely identify files?
...the hash are the same : you can only compare byte-for-byte. A hash is many orders of magnitude smaller than the number of different values for the whole file, so there are many, many, many possible collisions for each hash values. Only if you are in the case of copying a known file (with a known has...
What's the difference between fill_parent and wrap_content?

fill_parent (deprecated) = match_parent
The border of the child view expands to match the border of the parent view.
