I recently came upon an excellent and detailed account of how to recover a damaged sparse disk image.

I use encrypted sparse images all the time to securely store files. Sparse images have the advantage of automatically resizing as you add more files, so that you don’t have to devote a huge amount of disk space for the image until it’s really needed.

Hash a Pass was recently featured on Digg.com and is an interesting idea. Using a master password and a Javascript implementation of the SHA-1 hash algorithm, you can generate a secure and un-guessable password, and then simply re-generate it when you need it again.

A nifty trick, to be sure, but does this really make you safer?
