Can the :not() pseudo-class have multiple arguments?
...
What? so you would rather write .selector:not(.one):not(.two):not(.three):not(.four) { ... } than .selector { @include not('.one','.two','.three','.four') { ... } } ?

Why isn't sizeof for a struct equal to the sum of sizeof of each member?
...izeof(struct Y); /* = 8 */
const int sizeZ = sizeof(struct Z); /* = 8 */
One can minimize the size of structures by sorting members by alignment (sorting by size suffices for that in basic types) (like structure Z in the example above).
IMPORTANT NOTE: Both the C and C++ standards state that stru...
How to merge 2 JSON objects from 2 files using jq?
...If you also want to get rid of the other keys (like your expected result), one way to do it is this:
jq -s '.[0] * .[1] | {value: .value}' file1 file2
Or the presumably somewhat more efficient (because it doesn't merge any other values):
jq -s '.[0].value * .[1].value | {value: .}' file1 file2

JQuery .each() backwards
...(function (i) {
$(this).text( 'Item ' + (++i));
});
This demo here.
One more alternative is to use the length (count of elements matching that selector) and go down from there using the index of each iteration. Then you can use this:
var $li = $("ul > li");
$li.each(function (i) {
$(t...
Find index of last occurrence of a substring in a string
...eversed (i.e. original) string.
Watch out, though! If target is more than one character, you probably won't find it in the reversed string. To fix this, use last_pos = len(s) - 1 - s[::-1].index(target[::-1]), which searches for a reversed version of target.

Actual meaning of 'shell=True' in subprocess
...
Sorry my previous comment went before I was done. To be clear: I often see subprocess use with shell = True and the command is a string, e.g. 'ls -l', (I expect to avoid this error) but subprocess takes a list (and a string as a one element list). To run with out invoki...
