When I’ve started working with Git, besides using the quick how-to guides from the official site, I’ve also wanted to read a more detailed book about how this distributed VCS tool should be used in order to benefit from all of its functionalities.

The familiarity [...]

Booting Ubuntu from an USB stick is both fast and convenient: fast because an USB stick definitely has better R/W speeds than CDs, convenient because you can alter those files for how many times you want without buying several storage mediums (you could use a CD-RW, but that still would be slow). Nowadays USB sticks [...]

My move to HostGator was partly due to the fact that on my old host this blog got hacked. And judging by the impact, I suspect this was a server-side security breach because my DB was intact. Since then I’ve spent some time to secure my WP instance as much as I could given the [...]

After I had installed Firefox 3.6 on my Ubuntu machines I noticed that when I would want to open the FTP bookmarks saved in Nautilus those targets would open in tabs from Firefox. The problem with this approach was that I couldn’t edit files (create, update, delete) the way I could with Nautilus. After some [...]

Starting to work on my diploma project my setup required that I installed Oracle 10g XE and OC4J. For a while now Oracle has started to offer *.deb packages and to host a repository for Debian-based Linux distributions, which means that they have gained the maturity to be used in enterprise environments.
