Pressing C-h a will run the emacs function apropos-command which makes emacs prompt for words (or a regexp) to search for. It will then show a buffer containing a list of names and descriptions related to that topic, including key bindings for each of the functions available via keystrokes.

Vectors can be map'd and fold'd,filter'd andzip`'d:
Prelude Data.Vector> Data.Vector.map (^2) y
fromList [0,1,4,9,16,25,36,49,64,81,100,121] :: Data.Vector.Vector
Reduce to a single value:
Prelude Data.Vector> Data.Vector.foldl (+) 0 y

A Haskell project can either use the system wide packages or use a sandbox. A sandbox is an isolated package database and can prevent dependency conflicts, e. g. if multiple Haskell projects use different versions of a package.
To initialize a sandbox for a Haskell package go to its directory and r...

If you either have apps generated with pre-android support or just did that on purpose, you can always add android project to your app.

Consider this example function to check if a host is up:
is_alive() {
ping -c1 "$1" &> /dev/null
}
This function sends a single ping to the host specified by the first function parameter.
The output and error output of ping are both redirected to /dev/null,
so the functi...
