CHRIS REDDEN  Relying on permissions for security is a terrible idea. Anyone with root access to ANY computer can plug a physical drive into it and setuid/setgid to whatever they want. The only limitation is that you can't do that with the drive your currently booted off.

So if someone took the drive out of your computer and plugged it into their computer, it's already trivial for them to access all of your files regardless of the permissions you have set. All he did was change the _default_ behaviour on NTFS drive, so that you don't have to worry about users lining up between OSes.

The only secure way to keep your data is to encrypt it.

CHRIS REDDEN  Open up system preferences, go to displays and check the refresh rate your monitor is running at. Divide 1000 by your refresh rate. This number is the smallest increment, in milliseconds, that your monitor is capable of displaying a message for.

For example, a refresh rate of 60 Hz gives an increment of 16.7ms. This means the shortest amount of time the message can be displayed for is 16.7ms. The next increment up would be 33.3ms. The next would be 50ms. The slider in this application gives you the illusion that you have much finer control over the timing than you actually do, because your monitor only refreshes itself a fixed number of times per second (usually in the 50-100 range).

Also, addons for programs without built-in support are notorious for being unstable and quirky when updates to the base program are released.
