a=(1 2 3)
eval set -- "${a[@]}"
This code is often accompanied by getopt or getopts to set $@ to the output of the aforementioned option parsers, however, you can also use it to creat...

While eval may not be needed for a pop like function, it is however required whenever you use getopt:
Consider the following function that accepts -h as an option:
f()
{
local __me__="${FUNCNAME[0]}"
local argv="$(getopt -o 'h' -n $__me__ -- "$@")"
e...
The volatile keyword tells the compiler that the value of the variable may change at any time as a result of external conditions, not only as a result of program control flow.
The compiler will not optimize anything that has to do with the volatile variable.

OpenCL Kernels can be either executed on the GPU or the CPU. This allows for fallback solutions, where the customer may have a very outdated system. The programmer can also choose to limit their functionality to either the CPU or GPU.
To get started using OpenCL, you'll need a 'Context' and a 'Devi...
$logger = $container->get('logger');
This will fetch the service with the service ID "logger" from the container, an object that implements Psr\Log\LoggerInterface.
Many custom views need to accept user interaction in the form of touch events. You can get access to touch events by overriding onTouchEvent. There are a number of actions you can filter out. The main ones are
ACTION_DOWN: This is triggered once when your finger first touches the view.

In PHP, variable values have an associated "truthiness" so even non-boolean values will equate to true or false. This allows any variable to be used in a conditional block, e.g.
if ($var == true) { /* explicit version */ }
if ($var) { /* $var == true is implicit */ }
Here are some fun...
Suppose you are creating a function that requires no arguments when it is called and you are faced with the dilemma of how you should define the parameter list in the function prototype and the function definition.
You have the choice of keeping the parameter list empty for both prototype and d...
