Most of the current generation of computer nerds started out writing small programs in languages like BASIC. If you’re in your 30′s, chances are you started out on a Commodore C64, or one of its competitors, and fiddled around with writing small programs. Since then, computing has changed dramatically. Knowing your way around Microsoft Word makes you a “whiz kid” nowadays, and knowing how to install Windows can get you a job.

In my opinion, one of the coolest things about Ubuntu is that it comes with a Bittorrent client pre-installed. Transmission is an excellent torrent downloader. I use it all the time on my media server PC, both using the GUI (on my TV) and the web interface. I’ve even set it up so it watches my dropbox folder for new torrent files, so all I have to do to start downloading is power up the computer.

However, in order to make that work, Transmission needs to start automatically with Ubuntu. This used to be really straight-forward in older Ubuntu versions. You could simply add the terminal command “transmission” to the startup programs and that was it. Since “Meerkat” (or perhaps the version before that), this does not work any more.
