Article on BBC News website about how Egypt has removed itself from the Internet whilst the unrest is ongoing. Interesting to consider the implications for companies that rely on the Internet for their WAN connectivity for any offices they have in countries like this.

Wipe a disk using dd
You may need to wipe you hard drive to clean
up partition errors, bad installations, or for privacy. This will show you howto do this
These methods use a command called dd
Wiping the entire disk
This will overwrite all partitions, master boot records, and data.
Filling the disk with all zeros (This may take a while, as it is making every bit of data 0) :
dd if=/dev/zero of=/dev/sda bs=1M
If you are wiping your hard drive for security, you should populate it with random data rather than zeros (This is going to take even longer than the first example.) :
dd if=/dev/urandom of=/dev/sda bs=1M

NSA and compromised networks
Apparently the NSA think that their own networks can't be considered clean and security and take the appropriate actions based on that position including increased audit, new network sensors and standardisation.
