The coolest security hardware device ever

"The coolest authentication hardware device ever." -- Steve Gibson, Security Now!

Here are some excerpts from the Security Now! postcast discussing the Yubikey authentication hardware device Steve Gibson is referring to in his quote above.

Yubikey is an OpenID tool (one option is to use Yubico as your OpenID provider). Yubikey is also much, much more, as you will find out if you listen to the podcast.

Using Yubikey as an OpenID authenication tool, any time you needed to authenticate to an OpenID site you would just reach down and put your finger on the little touch surface of the YubiKey, and it would emit a one-time token.

YubiKey has a number of other features.  One is an anti-phishing feature. The authenticator is able to determine when the YubiKey's output was generated.

How to uninstall GRUB from my hard disk drive?

The GNU Grub FAQ has a section entitled "How to uninstall GRUB from my hard disk drive?"

I'll quote it below. However, I want to point out that I feel it is not an adequate answer. I found a better answer at another site, so keep reading.

There is no concept uninstall in boot loaders, because if you uninstall a boot loader, an unbootable machine would simply remain. So all you need to do is overwrite another boot loader you like to your disk, that is, install the boot loader without uninstalling GRUB.

For example, if you want to install the boot loader for Windows, just run FDISK /MBR on Windows. If you want to install LILO (I can't imagine why you want to do such a thing, though), run /sbin/lilo on GNU/Linux

 Here is where I found the better answer:

Best of both worlds - csv2ofx marries Yodlee with desktop personal finance apps

I'm starting to like GnuCash. Yodlee is great too. I'm a new user of both (started at beginning of this year), but I am already hooked, especially on Yodlee. Using these two apps together has allowed me to automate key parts of my financial management that I could never do before while also allowing me to do more sophisticated analysis. So what magic allows me to use these two apps together?

The key to upgrading my personal finance software was a free utility called csv2ofx. Without it, there is no way to get Yodlee data into GnuCash (or any other desktop personal finance app I know of).
