Is it generally faster to call an instance method rather than a class method?
Today I encountered something strange: I tried to put a utility method into an Utility class as a class method, so that I can simply call that method to generate me an convenient UIView with no hassle (not the imageNamed method but the other, much more complex one). It was horrible. The performance was so incredible bad. Then I made an i...

For instance, say I wanted a function to escape a string for use in HTML (as in Django's escape filter): def escape(string): """ Returns the given string with ampersands, quotes and angle brackets encoded. """ return string.replace('&', '&').replace('<', '<').replace('>', '>').repla...
How to get decent MySQL driver perfomance in Ruby
I notice that I am getting very poor performance for either or both inserts and queries. The queries themselves are basic and can execute with no delay directly from mysql.

THE FASTEST Smarty Cache Handler
Does anyone know if there is an overview of the performance of different cache handlers for smarty? I compared smarty file cache with a memcache handler, but it seemed memcache has a negative impact on performance. I figured there would be a faster way to cache than through the filesystem... am I wrong? ...

Good way to make animations with Cocos2D?
Hi there, I'm making a little iphone game, and I would get some clues. Let's imagine: Two background sprites moving pretty fast from right to left, and moving up and down with accelerometer. I guess I can't use animations here, cause the movement of the background is recalculated at each frame. So I use a schedule with an interval of ...

My guess is that it is actually running the same queries twice make for just under 900 queries per page (hope I am wrong) The ...
