A library of utility of generally useful PHP functions (filesystem, images, ini, text manipulation...). Outdated version of PHP.
<?php
// ============ strings ================
function smart_truncate($string, $limit, $break=" ", $pad="...") {
// truncates string to the first $break after $limit characters, then adds $pad to the end
// Original PHP code by Chirp Internet: www.chirp.com.au
// Please acknowledge use of this code by including this header.
// return with no change if string is shorter than $limit
$string = strip_tags($string);

Resume a dd operation with a check

This little script resumes an interrupted dd copy at a given offset.

Before resuming, it rolls back (the amount of roll-back is OVERLAP_SIZE * CHUNK) then calculate the checksum of the overlap on both files to make sure that they are valid images of each other.

The checksums have to be checked manually by the operator (todo: automate).

Deconstruct URL (quick regex)
window.location.href.match(/^([^/]+):\/\/([^/:]+):?([1-9]*)\/([^?]*)\??(.*)$/)
Example output:
["http://127.0.0.1:1337/projects/sd?sdflkj&jh", "http", "127.0.0.1", "1337", "projects/sd", "sdflkj&jh"]
That is: full match, protocol, host, port, path (relative to root), query string
Todo: test for bugs.
