About Me

When not at work with students, I spend my time in my room either reading, calculating something using pen and paper, or using a computer. I read almost anything: from the pornographic to the profound, although my main interests are mathematics and physics.

netbook maintenance

I'm still here at school even though it's already 9 pm. I'm downloading a security suite from Microsoft (it's part of the privileges of being a faculty member). The internet is fast here and doesn't disconnect compared to my home dsl connection.

I've upgraded the operating system from a trial version of Windows 7 Home Basic to a licensed Windows 7 Professional. I had to completely remove the trial version because the anytime upgrade feature doesn't work for my system. In the process, I needed to reinstall Adobe Reader, Firefox, Open Office, and the djvu reader. I also downloaded and installed drivers for my netbook.

I started working on it around 3pm until 4pm (when I had to go to a class) and then got back to it at 5pm and then I searched for and downloaded other programs.

I completed the installation of Windows 7 before 4pm. So from 5pm onwards I just downloaded the drivers, office, adobe reader, and Microsoft Forefront Client security. I'm still downloading as I type this, and I estimate that I will leave around 9:30 pm. The drivers are essential; the lovely visuals that Windows 7 offered depends critically on the drivers.

I did learn something new about Windows 7... the product key is not stored in the CD. I originally guessed that the key was encrypted somewhere in the CD, and that you could not complete the installation without because if the key you type in doesn't match the encrypted key, the installation will abort. The key has to be obtained from Microsoft, and their servers check if that key has been used by someone else. So one of the ways to cheat Microsoft is to guess a viable product key that has to both be (1) unused by someone else and (2) in Microsoft's list of viable keys. That's actually hard to do because a key has so many digits and it's alphanumeric, so that means trying 36 raised to the 25th power possible combinations. the verification process also takes time, so if the key is wrong, you will experience a 2 minute penalty.
