Timestamps in Truecrypt Traveler Disk

By default, TrueCrypt doesn't change the modification timestamp (shown in Windows as Date modified) of TrueCrypt containers when you change the files inside them. This is good when you want plausible deniability; the ability to claim, "look, I haven't touched that file in 3 years!". Unfortunately, it has the downside of breaking backup programs that use the last modified date to determine which files need to be backed up.

Luckily, you can change this behavior. In TrueCrypt, you can open Edit > Preferences, and uncheck Preserve modification time of file containers (see my post TrueCrypt timestamps). This setting is included in the release notes for Truecrypt 4.3a.

I found out the hard way that this setting doesn't apply to a TrueCrypt Traveler Disk. Because the Traveler Disk launches TrueCrypt using the Windows Autorun feature, it takes its marching orders from whatever parameters are passed in the autorun.inf file on the Traveler Disk, regardless of what you set in the Preferences. So, to turn off timestamp preservation, you need to add this parameter for TrueCrypt.exe in the autorun.inf file:
/m ts
The file probably already has /m rm, so right behind it add /m ts. This is the command line parameter for "Do not preserve container modification timestamp". See the TrueCrypt Command Line Usage page for this and other parameters.

The difference between burritos, chimichangas, and enchiladas

I love Mexican food, but I'm embarrassed to admit that I always get confused between burritos, wet burritos, chimichangas, and enchiladas. Here are the descriptions, with the differences in bold and pictures following each description.

A flour tortilla wrapped around a filling (meat, beans, vegetables, etc)

wet burrito
A burrito that's covered in red chili sauce and cheese. Because of the sauce covering, it looks like an enchilada, but it's made with a flour tortilla, whereas the enchilada is made with a corn tortilla.

A burrito that's deep-fried. Sometimes covered with cheese or another topping.

Considering retiring this blog

I'm seriously considering retiring this blog. When I started it in 2008, it was a place for me to share thoughts and links on a variety of topics. For at least the last year, however, it's just been a place where I re-post book reviews from Goodreads.

You can see all my book reviews on my Goodreads profile, and subscribe to my Goodreads RSS feed to be notified of new reviews. I also intend to keep blogging about WordPress, web design, and web-related topics on my OptimWise blog, which also has an RSS feed.

Would you miss this blog if I discontinued it? Please leave a comment.
