I am a huge fan of TimeMachine (the Mac OS X backup solution) and I like the approach of archiving whole files. The only drawback occurs if you have huge files (e.g., hard disk images for virtual machines) that are often modified.

Here a way to reduce the backup size of your VirtualBox hard disk images: simply create a snapshot of your machine. VirtualBox will then leave your hard disk image untouched and create a separate file with just the changes from the time of the snapshot.



When the snapshot becomes too large you can merge it and create a new one (by choosing delete snapshot the difference file will be merged with the hard disk image).

Psoriasis Area Severity Index (PASI) is the most widely used tool for the measurement of severity of psoriasis.

The computation is quite simple but it requires a lot of parameters. There are several pocket calculator but data input is painful and the feedback not optimal. I then decided to write a simple web JavaScript based application so that dermatologists could compute it quickly with an easy-to-use interface.

I moved all my pictures to MobileMe Galleries (the interface is much nicer than my album-made pages)

I just split the ETHZ hints page (with instruction on how to use VPN on a Nokia E90 Communicator) in two:

• a page with ETHZ-related hints (801.X, VPP, …)
• a page with E90-related hints (VPN, keyboard shortcuts)

I updated the list of yum repositories and configuration files that I am using with my Fedora 8 machines.
