WebKit

I have been working on WebKit for quite some time and here are some basics which can help people to get around the code base. I will be talking about the gtk port and working on ubuntu 11.04. Some one was asking what is the debugger to use it is GDB.
So first to start with webkit.org will give you the code , either download the nightly builds if you are just interested in using it or checkout the code from svn or git if you want to be the tip of tree and/or contribute patches to webkit.

The directory structure of webkit has gone through quite a few modifications.
The current code base has following directories of interest in the root directory->
Source =>has the entire code base
Tools =>has the sample applications like WinLauncher,GtkLauncher etc; scripts folder has many perl scripts for building, updating,create patches and run webkit tests to name a few
Inside Source
WebCore => has the code for html parser,tokenizer, css parser, loader,graphics,svg rendering,html rendering,websockets, webworkers and any new rendering engine related features code will be found here.
JavaScriptCore => has the code for javascript parser,interpreter/runtime compiler.
There are two other important folders WebKit and WebKit2 these are basically port dependent glue code and they have the API layer that is exposed to the applications.
The essential difference between WebKit and WebKit2 is that WebKit2 is a new API layer for WebKit designed to support a split process model, where the rendering engine runs in a separate process from the application UI.
In the next few posts i will try and take up each path and explain in detail..leave me comments if you want to know about some thing in specific

Hands on with OpenGL

I started working with OpenGL and thought it is worthwhile to document stuff I learn.
Development environment is Ubuntu 11.04 and im using mesa3d gl and freeglut3-dev libs for opengl libs.
how to compile:
if you have a sample program you want to compile do it as
gcc file.c -lglut -lGLU -o output
