An implementation of Kruskal's algorithm for generating mazes.
# --------------------------------------------------------------------
# An implementation of Kruskal's algorithm for generating mazes.
# Fairly expensive, memory-wise, as it requires memory proportional
# to the size of the entire maze, and it's not the fastest of the
# algorithms (what with all the set and edge management is has to
# do). Also, the mazes it generates tend to have a lot of very short
# dead-ends, giving the maze a kind of "spiky" look.
# --------------------------------------------------------------------
# NOTE: the display routine used in this script requires a terminal
# that supports ANSI escape sequences. Windows users, sorry. :(

Whatsapp like image compression
- (UIImage *)compressImage:(UIImage *)image{
float actualHeight = image.size.height;
float actualWidth = image.size.width;
float maxHeight = 600.0;
float maxWidth = 800.0;
float imgRatio = actualWidth/actualHeight;
float maxRatio = maxWidth/maxHeight;
float compressionQuality = 0.5;//50 percent compression
if (actualHeight > maxHeight || actualWidth > maxWidth) {

Lock and unlock a page's scroll position.

jquery.scrollLock.js

Useful for when a blocking user experience is needed (in my case, didn't want people unwittingly loosing their place by scrolling while a modal required their attention): $.scrollLock() locks the body in place, preventing scroll until it is unlocked.

// Locks the page if it's currently unlocked
$.scrollLock();

// ...or vice versa
