Aim, shoot, weigh! - hunting for samples in the forest of JIT

Many people are using OProfile for system measurements on Linux. This is a very handy profiling tool (supports hardware performance counters and has a very low runtime overhead) although it is in alpha phase. Using OProfile to measure any application performance is a straightforward task on Linux: you should get the latest OProfile for your machine or device, build, configure and run the daemon, and start measuring an application or your whole system. Finally, you can execute several scripts which report the performance numbers to you (according to your reporting requests). It sounds easy, doesn't it?

WebKitGtk+ cross compilation for ARM

WebKitGtk+ cross compilation consists of two parts. First, you need a cross compiler and the library dependencies of WebKitGtk+. Next, you have to setup the build system properly. You can reach this with some wrapper scripts.

Compiling QtWebkit with RVCT for ARM-Linux

There are a lot of make specifications in Qt, but none of them is suitable for RVCT compilation. So, if you want to compile QtWebKit with RVCT, you have two options: either you create a new specification or you can use an existing one with wrapper scripts. In this post I'll describe the second option.

What are JavaScript and SVG good for? - Built-in Flash engine?

There is a very interesting open source project: a Flash runtime engine written in JavaScript, called Gordon, written by Tobias Schneider. Although the project is still under development, you can get the first impressions how strong the JavaScript and SVG technologies are nowadays.

QtWebKit cross compilation with GCC for ARM-Linux

When I tried to cross compile QtWebKit for ARM-Linux, I didn't find any clear description, so I have decided to write a blogpost about it. It's not too hard, but if you have never done something like this, it can be a little bit confusing. In this post, I will describe this method in some simple steps.
