I have been a linux user since 1996, this started with Slackware 2.6,
I have configured xinitrc, lilo, grub, xconfig, fstab, etc..
Then with Slackware 7 I installed Apache, PHP, MySql, I made bash files, c++ applications and perl scripts.
I then had relatively old hardware compared to the time, so I spent a lot of time reconfiguring the kernel and recompiling it.
I created fvwm configs for my machine which ran very fast compared to other window managers.
From slackware I moved on to Debian, which still involved configuring the xconf file, more recently with debian
I installed applications such a compiz, for 3D window management.
My text editors include eclipse, vim, emacs, nano or gedit.
I have made Make files, installed the LAMP stack made programs in php using mySQL.
I have configured Apache, lighttpd, nginx, php. Have used apache, lighttpd and nginx for virtual hosting.
I have programmed Ruby on Rails and set up mySQL.
I new use Ubuntu and am a competent CLI user.
I have also installed Gentoo, Sabayon and FreeBSD.
I have looked into Mono for c# development but have a preference for Python and django.
I have installed svn, used svn and cvs.
The latest example of my python can be seen at http://code.google.com/p/ajaxmmo
I have remote accessed other Linux machines using ssh (including X11 redirection) and VNC.
I have used web control panels such as cpanel and the django panel.
