GPS and compass project - Breadboard prototype

PHP: Easy integrated benchmarking

Source code

When I began developing PHP I found the biggest stumbling block for me was learning the best practices and many nuances for greater performance, especially when querying a database.

Quick tip: Firebug console output

Source code

I’ve found debugging my JavaScript projects much easier since using the Firebug add-on for Firefox, but more specifically outputting to the Firebug console.  It’s as easy as this: var myVar = 42; console.log(‘my variable: ‘ + myVar); This will output ‘my variable: 42‘ to the Firebug console, just like using System.out.println() in Java.
