Autotrash is a simple Python script which will purge files from your trash based on their age or the amount of free space left on the device. Using autotrash -d 30 will delete files which have been in the trash for more then 30 days. It uses the FreeDesktop.org Trash Info files included in the new GNOME system to find the correct files and the dates they where deleted.
Features:
Remove files that are older then a given number of days (see the -d option)
Purge older files to ensure a specific amount of disk space is free (see the –min-free option)
Check for remaining disk space, and only delete if you are running out (see the –max-free option)
Delete regex matching files first (see –delete-frist option)Install autotrash on ubuntu

Pipelight, which allows to run your favorite Silverlight application directly inside your Linux browser. The project combines the effort by Erich E. Hoover with a new browser plugin that embeds Silverlight directly in any Linux browser supporting the Netscape Plugin API. He worked on a set of Wine patches to get Playready DRM protected content working inside Wine and afterwards created an Ubuntu package called Netflix Desktop. This package allows one to use Silverlight inside a Windows version of Firefox, which works as a temporary solution but is not really user-friendly and moreover requires Wine to translate all API calls of the browser. To solve this problem we created Pipelight.
Pipelight consists out of two parts: A Linux library which is loaded into the browser and a Windows program started in Wine. The Windows program, called pluginloader.exe, simply simulates a browser and loads the Silverlight DLLs. When you open a page with a Silverlight application the library will send all commands from the browser through a pipe to the Windows process and act like a bridge between your browser and Silverlight.

Most current SSDs support the ATA_TRIM command for sustained long-term performance and wear-leveling. On Linux TRIM is supported by the Ext4 and Btrfs filesystems but the latter is out of the scope of this tutorial. We need two things in order to enable TRIM:
- Installed and working Ubuntu or other GNU/Linux distribution with root and text editor. We use
geditfor our editing purposes, but if you have another tool on your machine – you are free to use that instead.- Linux kernel 2.6.33 or later. Ubuntu 10.10 (Maverick) ships with kernel 2.6.35. This kernel is also available for Ubuntu 10.04 (Lucid) via a backport package.
Having met the two requirements, all we need to do to enable TRIM is the following:

If you are using a Solid State Drive (SSD), you should know that you shouldn’t run any defragmentation or free space consolidation software on it. So how do you clean up your SSD and free up the empty space? TRIM is the command we use to inform the OS to do the cleaning job. Windows 8 comes with the “Optimize Drive” feature that can run the TRIM command regularly. What about Ubuntu? How can you enable TRIM for SSD in Ubuntu?

In Ubuntu (and any other Ubuntu-based distro), when you use a “sudo” command, the system will prompt you for your password. After the first “sudo” command, the system will remember your password for the next 15 minutes so you don’t have to enter any more password for subsequent “sudo” command. If, however, you feel that the 15 minutes is a bit too long/short, here is how you can change it.
