For the curious/inquisitive:
The 'wee bit' extra to the partition is to ensure that rounding at the cylinder boundary doesn't create a partition that is slightly smaller than RAM. With a spot of Googling, you could no doubt find out the exact amount of space to 'over allocate'. It's likely that a smaller amount of space could be used but life's too short to worry about tens of Mb on a 100Gb disc, especially in a home PC environment. I just use a lazy broadbrush power of 2 amount - nothing scientific, sorry.

Disc cleanup for Ubuntu & variants:
1. Using your favourite filemanager (normally Nautilus), go to /home/user
2. Menu, View, Show hidden files
3. Navigate to .thumbnails
4. Delete whatever you find in their.
:)
[Or for the brave]
In a terminal (replacing user with your own login name):
rm -R /home/user/.thumbnails/*
