1 MB truecrypt filesystem file created, formatted FAT with AES-Twofish-Serpent encryption and SHA512 hash.

Copied it for empty versus adding a file.

Added a 453 byte file to one.

command: diff test.tc test\ \(copy\).tc -a > truecrypt.diff

du -h truecrypt.diff
8.0K truecrypt.diff

It changes far too much.

That's because TrueCrypt uses blocksize of 4K.

I've been using spideroak, and I have one complaint which is restorations are sometimes fairly slow (10 minutes to pull down a 300k file). Sometimes it's fast-ish (30 sec) , so I guess it's where the file is in their cloud.

How is restoration time on Dropbox?

As fast as Amazon S3.
It's funny. Laugh.

Pigeon Protocol Finds a Practical Purpose 113

Posted by timothy from the fly-away-little-one dept.
Selanit writes "Since David Waitzman wrote his tongue-in-cheek Standard for the Transmission of IP Datagrams on Avian Carriers, there have been occasional attempts to actually transmit information via pigeon. One group back in 2001 successfully sent a PING command. But now there's a practical use for pigeon-based communications: photographers working for the white-water rafting company Rocky Mountain Adventures send memory sticks full of digital photos via homing pigeon so the photos will be ready when the rafters finish up. The company has details on how the pigeons are trained and equipped. It may not be a full implementation of the Pigeon Protocol, but it works in narrow canyons far off the beaten path — and just as David Waitzman presciently predicted, they occasionally suffer packet loss due to hawks and ospreys."
