How to detect DIV's dimension changed?
...ion. It uses an event-based approach, so it's damn fast and doesn't waste CPU time.
Example:
new ResizeSensor(jQuery('#divId'), function(){

Hashing a file in Python
...chunks the hash function finds ideal which makes it faster or at lest less CPU intensive to compute the hash function. So instead of disabling buffering and trying to emulate it yourself, you use Python buffering and control what you should be controlling: what the consumer of your data finds ideal,...

Why use armeabi-v7a code over armeabi code?

Do take some benchmarks for your particular application, but removing the armeabi-v7a binaries is generally not a good idea. If you need to reduce size, you might want to have two separate apks for older (a...
