Another post for my fading memory, how to install the GD libraries for your Leopard Apache installation running PHP 5.2.5. I will be using these libraries in a forthcoming blog about the use of ‘sparklines‘ to present complex performance monitoring data. Now on with installation. Thanks to topicdesk for leading the way with detailed OSX 10.5.x [...] If you’ve been using a Macbook Pro or similar for some time, you’ll find that their batteries need tender love and care, if they are to go the distance.

Despite having some initial issues with the code, the author of the jmx4r module turned around [...] I quite literally stole this idea from Charlie at PerformanceEngineering in which he posted a response to a challenge by Dmitry on how to get regular expressions up and running within LoadRunner. I’m a huge fan of regex, and thanks to these guys, now have a way of implementing at least pattern matching with LoadRunner. Ideally [...] HP LoadRunner Analysis is a free tool right?
