By Yannick Loth, on August 1st, 2010%

This is the line defining my bash prompt in .bashrc, using some colors:

PS1=’\[\e[0;32m\][\u@\H\[\e[m\] \[\e[1;34m\]\w\[\e[m\] \[\e[0;32m\]]\[\e[1;32m\]\$\[\e[m\] \[\e[0m’

This is what my prompt looks like:

If I’m not wrong, the characters in bold give the content of the prompt, the other ones are color-codes.

I currently haven’t found out how to use this prompt by default for all users, even existing . . . → Read More: Color in bash

On the web, you’ll find how to setup ArchLinux with LVM, or with RAID, or with encryption, but not with the combination of these three technologies. This article explains the different steps I took to setup these three technologies with ArchLinux.

My experience with Arch Linux x86_64

By Yannick Loth, on May 18th, 2010%

My laptop currently runs the 64-bit version of Arch Linux.

The last time (some years ago, I must admit) I tried to run a 64-bit Linux distribution, I was disappointed by the issues that existed with some Firefox plugins, Skype and some other 32-bit applications.

Some weeks ago, as I had to reinstall my laptop and thought it’s . . . → Read More: My experience with Arch Linux x86_64

Arch Linux: faster pacman

By Yannick Loth, on January 8th, 2010%

Instead of using pacman,I use pacman-color.
Instead of using pacman-color, I use powerpill.
Instead of using powerpill, I use yaourt.
Well, that’s the chain of wrappers around pacman I use:
yaourt->powerpill->pacman-color->pacman

This provides colorized output and parallel (thus faster) package downloads.

Simply change in /etc/yaourtrc:
PacmanBin = /usr/bin/powerpill
and in /etc/powerpill.conf:
PacmanBin = . . . → Read More: Arch Linux: faster pacman

Endian Firewall Community 2.3

By Yannick Loth, on November 2nd, 2009%

This week-end, I managed to reconfigure my complete home network to use a virtualized instance of Endian Firewall 2.3 Community. And it rocks.

You simply download the ISO file, install it in a new VM, connect to its web interface, and that’s all. Or almost. I think even people without much knowledge of TCP/IP would be able . . . → Read More: Endian Firewall Community 2.3
