Recently I had to encrypt an entire partition to protected some sensitive data. I found out that TrueCrypt is quite easy to use and provide pretty good protection against attackers with physical access to your machine.

You can encrypt your data in two ways:

1) By creating an encrypted file which you then mount as a regular disk

2) By creating an encrypted partition in a similar fashion.
I am running on ArchLinux but you should have any problems installing truecrypt with any distro’s software installer. In case you’d like to do it manually, just follow this link.

When you are done with the installation make sure that you load the kernel module with ‘modprobe truecrypt’. Remember that all commands are executed as ‘root’. You can use a regular user if you give him access to the truecrypt utility through sudo.

For one of my projects I had to find the exact domain name extension using a php script. While, this doesn’t seems too hard to do for a simple domain name (i.e domain.com) by just exploding the domain string and separating the two arrays items by the dot character, I had to do it a little bit more .. sophisticated let say. Generally a domain name string should look like domain.com, but what if the user types www.domain.com or even worse my.section.at.department.university-name.edu.

They say that everything has its first time … Well, I believe that this was my first problem I have ever had with Firefox. I have tried to install a dictionary from:

https://addons.mozilla.org/en-US/firefox/browse/type:3

I already have the English dictionary installed but I needed an additional one. Unfortunately, the following error is generated every time I try to install the new package:

Firefox could not install the file at:

…..

because: Not a valid install package

-207

I have Googled the error and have found some strange advices regarding this error. Unfortunately, non of them actually resolve my problem. The first one was to restart my browser and try again, another one — to “download the desired package on your desktop and try install it locally” — no luck again.

I have also checked the Knowledge base but I have not been able to find any solution for this issue. Although, my Firefox version is up to date I have downloaded the application again and reinstalled it which, unfortunately, does not resolve the problem either.

I have found a very strange reply in one forum regarding this issue:

There was a problem last night with the new Mozilla Add-ons site. They seem to have reverted back to the old site today, and you should find that you can now download and install without difficulty.

Personally, I don`t believe that this is the case. So … if anyone knows what the the problem is here, please leave a comment :). Thank you in advance.
