github has recently disabled downloads feature sysutils/pefs-kmod port was relaying on. github downloads were frustrating but less hassle than hosting PEFS elsewhere and having to deal with two bug trackers, repositories, etc.
Downloads moved to code.google.com, but I intend to continue using github for bug tracking and as main source repository.
PEFS - code.google.com/p/pefs
ggateu - code.google.com/p/ggateu

Two month ago I've decided to encrypt some personal files, which wasn't a big deal thanks to stacked crypto file system we have in FreeBSD :) This weekend I've realized that the worst thing that could possibly happen to encrypted data did actually happen -- I couldn't recall the password.
Decision was made to roll back ZFS transactions to recover deleted snapshot. Performing such dangerous operation on personal laptop wasn't an option. Especially considering there was no spare disk laying around for a backup. So I've started hacking on ggate to create a union provider.
The key idea behind ggateu was not to use matadata storage but to relay on the fact that probability of encrypting disk sector into all zeros in negligible. That's the same trick used by PEFS to handle sparse files.
Utility available for download here: https://github.com/glk/ggateu
It worked for me, it's likely to be buggy and it's great for file system experiments!
p.s. Right after finishing initial version of ggateu it became clear ZFS uberblock for that particular transaction was long gone. By spending another half an hour typing semirandom passwords I've recovered my files. Still have no idea what the password was.

Graphics mode in recently release links 2.6 changelog sounded vaguely familiar. So I've started googling for my first non-trivial contribution to a open source project. It was in 2003 - nearly 9 years ago. I wish I have that patch to look at :D
 can't recall much of it, mozilla was too buggy and elinks unusable. used FreeBSD :)
