Recently I did a lecture on the magical world of vim. Despite having used it for quite a long time I realize there is still far more that I could know about it, but there is also more that I haven’t published on this blog. Some of you might remember some of my earlier posts on vim [here], [here].
Ubuntu includes a very limited shortcut key configuration utility which doesn’t allow you to assign hotkeys to your own applications or scripts. To get around this limitation, we can use the built-in gconf-editor utility to assign them ourselves.
First you’ll want to load up gconf-editor by typing it into the Alt+F2 Run dialog.
SSL requires applications to be modified as it operates above the TCP layer and this happens in user space in linux and other OSes.

You hear about the great macro feature of Emacs all the time. You see cheat sheets for Emacs key combinations all the time. But you never quite see the keyboard macro trick demonstrated clearly. Here's how it works:
This document describes how to install a Proftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota with this setup.
Pretty much since I started using Openbox, I’ve been wanting a simple way to change the wallpaper from the right-click menu.
