I have a “thumb drive” attached to my keychain. That way, I always have information with me and I don’t leave my drive behind when I leave (since I can’t go anywhere without my keys). I keep two sets of files included on the keychain.
First is a set of personal files that are encrypted with TrueCrypt – a free encryption program. I can decrypt them on any computer I want just by running the Portable Mode of the program.
The second set of files is my computer geek recommendation for the day: PortableApps.com
With this platform, you can run a set of applications from your portable USB drive without ever installing the programs to a computer. When you surf the internet, all the cookies and site information stay on your USB drive. If you want to use a program and it isn’t installed on the computer you are using, you can plug in the USB drive and use the PortableApp application.
There is a long list of applications you can use with the platform and all of them are free.
I like using Firefox as a browser, but our hospital computer only uses Internet Explorer. So I plug in my USB drive and I’m running Firefox in no time. I can also run Google Chrome if I want.
There are also several games you can run, including Sudoku, poker, and a Wolfenstein-like game called AssaultCube.
Comes in very handy … and it’s free.
