I was working on a big website recently and faced a really tedious job in editing the content. I needed to find and replace certain words, like 'southeastern' for 'southeast', scattered over something like 140 files in half a dozen folders. What to do?

Introduction To The Enlightenment 17 Window Manager For X (Ubuntu 11.10)

Filed under
Ubuntu
HowTos

This tutorial is supposed to show some features of the Enlightenment window manager as an alternative to the often used Gnome and KDE managers. I will install Enlightenment on a desktop computer with Ubuntu 11.10 installed. Apart from the login screen however, all of the controls shown on the screenshots should be the same for every installation of enlightenment, whatever distribution you install it on. Enlightenment is already included in the Ubuntu repositories, therefore Ubuntu users and those of any Ubuntu derivatives won't have any problems installing it. It is also available for download for most other distributions though.

freesoftwaremagazine.com: I've gotten a lot of personal pleasure from the free software astronomy tools that are included in my Debian GNU/Linux system. But ironically, I haven't written about them much. Recently, though, I was asked a question, so this is a good chance to talk about how to use it.

Setting Up Unison File Synchronization Between Two Servers On Ubuntu 11.10

Filed under
Ubuntu
HowTos

This tutorial shows how to set up file synchronization between two Ubuntu 11.10 servers with Unison. Unison is a file-synchronization tool similar to rsync, but the big difference is that it tracks/synchronizes changes in both directions, i.e., files changed on server1 will be replicated to server2 and vice versa.

Enabling Compiz On Linux Mint 12 (GNOME Classic)

Filed under
Ubuntu
HowTos

This tutorial shows how you can enable Compiz on a Linux Mint 12 Lisa desktop (the system must have a 3D-capable graphics card - I'm using an NVIDIA GeForce 8200 here). With Compiz you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop. Compiz is not supported on GNOME 3 yet, that's why this how-to is applicable only for the classic GNOME desktop.

For a demonstration in a class I'm teaching, I recently assembled a video from a PNG stream with Sintel (except just the trailer, it was a more manageable size for the demo).

My example's a bit different, so bare with me.
