Linux Development
Browse the Linux Kernel Source with LXR
LXR (stands for Linux Cross-Reference), is a great tool which indexes the source code of the Linux Kernel and allows you browse the source in your favorite browser (Firefox), with quick references for all functions/files referenced in that code. (it’s not limited to use in Linux Kernel though, and can be used to index any large project’s source code).
Whenever I need to touch the Linux Kernel code, I first open a new tab with LXR, another with Google ready to work, and a shell terminal ready for grep queries.
Add Colors to Your Manpages
I use the manpages a lot. Manpages are a very useful database of information for linux users and developers. The problem with them is that their appearance becomes boring after a while.
I already wrote a post about reading them from firefox, so they’re displayed in a nice way as html pages.
In this post we’ll add colors to the manpages viewed from inside the shell.
First, open your ~/.bashrc file. To open it with gedit you can type:
gedit ~/.bashrc
Manpages for Linux Development
This year I’m taking a course in Operating Systems, and it looks like I’m loving this area. I’m going to post here problems I face during the course, and their solutions, so I can find them easily next time I need them. As a side effect, I’ll be sharing them with the world. 
The first problem I faced is with the manpages: Sections 2 and 3 of the man pages are necessary for development on Linux: Section 2 is about system calls, and section 3 is about library calls. These two sections do not come with the default Ubuntu installation (after all, Ububtu is for human beings!). So I was surprised when I typed “man 2 sigaction” and got this message:
