[ad#ad-1]When I used Windows, I had come across several “system cleaners and optimizers”. One I liked was CCleaner (Crap Cleaner). It had a nice interface and was capable of cleaning cache and data of several applications.
I found a similar application for my Ubuntu 10.04 Lucid Lynx Alpha. It has similar interface and features. It is called bleachbit and can be installed via Synaptic (universe repos need to be enabled) and can be accessed from Applications>System Tools>Bleachbit. It is also capable of wiping the data so that it is impossible(or lets say difficult) to recover. It can also clean backup files (those hidden with ~ at the end of the filename, .bak, .tmp and more) with Deep Scan.
You just found a solution to your problem in google, but cannot view it because the site that requires you to be a registered user.
How do you bypass compulsory registrations to such sites?
Well, I used bugmenot most of the times. But bugmenot does not contain login for all sites (unless of course somebody posts it there) and some sites ban users whose login information is posted in bugmenot.
Solution: Use Google Cache.
Most sites allow google bots to view and cache the page contents so that they get their content indexed in Google. You can view the page the by simply clicking Cached.
