Ubuntu - linux

Setup ubuntu today.
First impressions:
- Very simple to install (very simple partition manager).
- GUI looks similar to fedora.
- Music started playing without any messy configuration( had to struggle to get it working on fedora)
  Bundled radio stations started singing the melody....
- Was looking around for a cool applications equivalent for ubuntu like "easylife" installer in Fedora.
sudo aptitude install [application name] looks reasonable but not so cool like eaylife.
- Windows XP gets automatically detected and drives get auto mounted.
- More to come..

Cleanup dirty code using the power of regular expressions

In eclipse search for all irrelevant comments and clean them up:
/\*\s(\r\n.*\r\n)+(\s)+\*.*(@see)*.*(\r\n)+(\s)+\*/
or
For finding all comments blank use >> (?m:)/\*\*(\r\n)+(\s)+\* @[^/]*/
Note: m tells eclipse to search multi line.

Eg:
/*
  *
   * @see ...
   */

The above pattern can be cleaned up very easily with pattern above.
