I just read and loved Twyla Tharp's book; this is a summary of the main points.

So I won't be spending the month of April toasting 50 years of the overopinionated and underinformed little book that put so many people in this unhappy state of grammatical angst. I've spent too much of my scholarly life studying English grammar in a serious way. English syntax is a deep and interesting subject. It is much too important to be reduced to a bunch of trivial don't-do-this prescriptions by a pair of idiosyncratic bumblers who can't even tell when they've broken their own misbegotten rules.

New to Ubuntu 8.10 is a nifty seamless encryption feature. It's always been possible to encrypt individual files/folders in Ubuntu but it involved creating a key pair and then individually encrypting files. To view or edit the file, it was necessary to decrypt it and then re-encrypt it again if changes were made. Messy.

The new feature creates an encrypted filestore, mounted in the Private folder in your /home directory. This is automatically locked and unlocked as you log in and out, so accessing it is seamless and transparent. Other users won't be able to access it, and it isn't possible to see its contents by booting into rescue mode.

To activate the feature, just type the following two commands:

sudo apt-get install ecryptfs-utils
ecryptfs-setup-private

Follow the prompts shown and then log out and back in again. Once the desktop reappears, you'll see a new Private directory in your /home folder, where you can save data, as with any other directory.

No longer recommended, but nice nice review.
