Inspired and adapted from a math joke:

Why do computer scientists always confuse Halloween and Christmas?
Because 31 Oct = 25 Dec.

Gnome 3: go to Shell? Not just yet, thanks.

In Debian Unstable the transition to Gnome 3 is taking place; when Gnome 3.0 firstly came out some unnamed geeky users complained loudly about the design decisions of the development team to push strongly towards gnome-shell as a new default UI; gnome-shell was designed focusing on usability (usability is a metric relative to a certain target audience BTW) and simplicity, hiding a lot of details from the users. Obviously you can never make everyone happy so some of us simply happened to be “out of target”: you know us computer people (*cough cough*), we like to be in charge and control The Machine...

ssh tunnelling with Telepathy and ssh-contact

I needed to connect remotely to my brother's computer to help him fix something, in the past I relied on the X Windows protocol for these things: the people I was helping just needed to open a remote xterm on my screen (with $ xterm -display my.public.ip.address:0.0) to let me operate on their system , it was insecure —no encryption in the communication— but it was one simple command for them to copy and paste as I were putting on my end all the boring details about port forwarding and access control, but this time I wanted to try something different.
