Setting up a Raspberry Pi as a home web server is a great way to learn about web design and server administration. A Raspberry Pi uses much less power than a PC, and takes up much less space. The fully featured Linux operating system comes with lots of software, including the Apache web server which is used to host some of the world’s biggest web sites.

Let face it, the Secure Shell (SSH) daemon running on your VPS is the most sensitive service open to attack on your system. Any hacker worth their salt will first try to gain access to your VPS via SSH and 99.9% of all VPS connected to the internet run this service by default and on their public IP.
If somebody gains access to your VPS via the SSH service, you can kiss your data and entire VPS goodbye. This is the ultimate goal for any would-be hacker and as such, needs to be the first thing you secure as a VPS administrator.
In this article I’m going to show you how to take three simple precautions with the SSH service that will stop most hackers and script kiddies in their tracks.

Note that while the article and title makes reference to a Virtual Private Server (VPN), there is no reason these techniques would not work with any version of Linux that offers SSH access.
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

If you are keen to get your hands on the latest Android 4.3, but your phone’s manufacturer/carrier is not ready to push the update to your phone yet, you can try it out on your desktop. You doesn’t have to install the Android SDK or emulator. As long as you have VirtualBox in your computer, you can run Android 4.3 in a virtual machine.
We have previously shown you how to do so with Android 4.0 (Ice Cream Sandwich), but the build back then was not working well and the WiFi module is not working. This latest Android 4.3 build is more complete and a lot of things just work out of the box, even when you run it as a LiveCD.

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:

Say for instance you wish to block IP ranges by region such as blocking China. This is easy to do with one spiffy website and ufw in Ubuntu or other Linux distros. I’ll show you how!

Consider that a Raspberry Pi costs $35 (for the higher end model) and for that money you get no case and no power supply. Now look at what you can get for $45, or perhaps a bit more if you want a more powerful device. If you were going to use a Raspberry Pi with XBMC or some other media center software, you might want to wait until the reviews for this device come in (we’d love the chance to review one, if anyone from SolidRun happens to read this!). Note that it has optical audio SPDIF out, which is something the Raspberry Pi doesn’t offer!
