Raphaël-JavaScript Library

Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.

Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël's goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.

Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.

Timechart: Finding out why your Linux computer performs the way it does has

  
Finding out why your Linux computer performs the way it does has been a hard task. Sure, there is Oprofile, and even 'perf' in recent kernels. There is LatencyTOP to find out where latencies happen.

 But all of these tools are rather limited when the software stack that has the performance issue is more complex than a single program. The tool that comes closest to being useful is `bootchart', but that has a rather limited resolution.
