Access physical memory from Linux user space

If you want to find a way for access physical memory in Linux there are only two solutions. The first is to develop a module running in kernel space with the correct privileges to access physical memory and the second is to use a special devices called " /dev/mem ". If your purpose is only to read or write some small parts of physical memory from user space this device is the right solution for you.

Browse android source code in a quicker way

The Android package is composed of an huge amount of sources code and, since the documentation about internal structure is virtually non-existent (except some text files around that doesn't help very much), the only "documentation" are the sources code itself. Using some tool like grep is possible to search inside sources tree but it take a large amount of time and the output could be very hard to "follow". The following site could be a very very useful tool for make quick search inside Android source package. Basically it have already indexed all the Android versions from 1.6.0 to the last and allow advanced searches inside Android sources tree. The search result is well formatted and each language elements (functions. defines, variables and so on) is linked for allow to jump very quickly between the code inside source files. I strongly suggest to give a try!
