NFS or Network File System is a quick and easy way to share files between Linux hosts on a network. Client machines are able to mount specific directories on a server machine and access the files as if they are on the client's local filesystem.
Configuring an NFS share is as easy as installing a package and editing a config file. For the steps below I'm using a Debian client and a Ubuntu based server.
Configuring the server
Begin by installing the nfs-kernel-server package if it isn't already installed:
sudo apt-get install nfs-kernel-server

The Gnome 3 default behaviour for Alt-Tab switching displays applications across all virtual desktops and groups together multiple instances of the same application.
If you find this annoying, the list of applications can be limited to the current virtual desktop, using the command:

I wrote a utility to write content directly to .vdi files.

Restarting a wifi connection without rebooting
I have a Mythbuntu box who's only connection to the outside world is through a wi-fi connection. It can be frustrating when the connection drops out at a critical time - during an upgrade to the next LTS release for instance. Here are some things to try to reset the connection.

In this article I will demonstrate one way to backup up a Debian based web server, together with MySQL databases.
The concepts shown here should easily adapt to work on most Linux distributions.
The tools we will use include rsync, mysqldump and tar.

This is a post for the sole purpose of testing the comments functionality.
Today we will build Ogre3D graphics rendering engine (http://www.ogre3d.org/) using Microsoft Visual C++ 14.0 compiler (Visual Studio Community 2015).
Building Ogre can take some time and things don't always go smoothly, which is why I decided to document the entire process. I will follow the basic process as documented in the official guides:
Just be aware that I may be using a slightly different directory structure within my build. Substitute my paths for yours where applicable.
The latest stable release is 1.9 and has been around for a long time, so it should build without too much trouble.

Linux + Apache + MySQL + PHP
Probably the most common installation of web server, at least for a Linux system, is Linux, Apache, MySQL and PHP. Also possible on a Windows system, in which case it would be known as WAMP. I will cover setting up the former here.
I assume you already have a working Debian based Linux distribution. If not then I highly recommend Debian, or for Raspberry Pi users, Raspbian.

There are a few simple steps I consider important to securing a new Raspbian installation:

- Remove the default pi user
- Prevent root login
- Use ssh key-pair authentication
If your Raspbian image came pre-installled with X.org and GUI components you may want to remove them to free up some space on your partition. It's quite easy to do and highlights some useful commands:

Today we will build Boost C++ libraries (http://www.boost.org/) using Microsoft Visual C++ 14.0 compiler (Visual Studio Community 2015).
We will build both 32 bit and 64 bit binaries.
Download and extract files
Download the latest release (at this time Boost 1.59.0 hosted on SourceForge) http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.zip/download
Extract the files to a directory of your choice; I use /lib_source/
I like to keep my third party libraries separate from my own projects. I copy the final compiled binary files to a separate location, depending on the compiler used. For MSVC 2015 the folder is /lib_msvc14 (for MinGW it might be /lib_mingw47). You get the idea.
