Quite some years after the iPhone was introduced it still seems that everybody wants to have one to send email messages. But what if you just can’t afford it? In this short post I would like to show how to setup your email client so it looks like you were sending these messages from your shiny iPhone. It’s easy, quick and fun.

HTML select box to download files
January 21st, 2010 — Tech
Just recently I wanted to have a simple HTML select element where the user should be able to click on a specific option to download a certain file. I came up with a solution that contains some JavaScript and straight forward HTML markup.
The HTML markup consists of a simple HTML select element that triggers a certain JavaScript function via the onChange hook. The JavaScript function in turn just sets the window.location to the given file and so the browser starts downloading.
Profiling with CPU-Sampler
January 13th, 2010 — Tech
Apple’s Xcode comes with a neat profiling tool called CPU Sampler. It helps you identifying time consuming code blocks in your software and is really handy if you need to optimize for optimal performance.
Just recently I tried rewriting OpenGL’s routines that handle matrix calculations as part of a lecture at the university. Pretty soon I came to the conclusion, that I had to optimize my code if I wanted to compete with the implementation provided by OpenGL.
This post presents at quick look at CPU Sampler which helped me making well-founded decisions resulting in a faster implementation.
WordPress: Adding a sidebar to your theme
January 5th, 2010 — Tech
In another post I discussed the idea of placing a sidebar into your theme and using it to manage the navigation menu of your site. I came to the conclusion – proposed by other people from the WordPress community as well – that you can use a sidebar for basically anything but not just a sidebar.
Although you can find this information in the Codex too, I would like to show you how easy it is to add a sidebar somewhere into your theme. You’ll see that it’s just about adding some function calls here and there – that’s it and you’ve got a new sidebar that can hold arbitrary widgets.
