In the wise words of Wikipedia, "Virtualisation is a broad term that refers to the abstraction of computer resources". Within this definition sits a whole variety of products - Sun's VirtualBox, Parallels, Bochs, Xen, KVM, Qemu, various flavours of VMware and many others. And there's a great deal of jargon to confuse the unwary - emulation, full virtualisation, paravirtualisation, virtual appliance, hypervisor... the list goes on. And not everyone agrees exactly what all these terms actually mean.
We're going to deliberately sidestep the jargon and the hype to take a practical look at the virtualisation technologies in Ubuntu, in particular KVM and Qemu and the related userspace tools that create and manage virtual machines. Although the discussion centres on Ubuntu, the technology is applicable to all Linux distros.
Warning: if you're a little less experienced (or a little more time constrained!) you might find our other article, virtualisation made easy, a little easier to read.

In our previous two tutorials (see here and here), we created a Simon-type game using the Arduino, a hardware platform for simple, and not so simple, electronics projects.
We placed three buttons and three LEDs on to something called a breadboard, and wrote a small program that would send a random sequence to the LEDs, which the player would then need to replicate by pressing the buttons in the same order. Each time you got the sequence correct, the sequence would be extended by one and repeated. The further into the random sequence you got, the higher you scored.
In this, part three, we're going to build on what we already created and add another important feature - sound! So, get the hardware out, make some coffee, and prepare for some hardware hacking fun...

A few years ago, British newspaper The Telegraph covered the UK government's budget announcements by posting tweets onto their site that included the hashtag #budget. As you can imagine, this was soon abused, and Twitter users had much fun at the Telegraph's expense.
Well, apparently Mozilla hasn't learned, and so we were surprised to find a curious link on the Mozilla.org front page this morning, promising "Screenshot - Free Hard Sex Videos, XXX porn, Hot Sex...", apparently on the grounds that the link in question had "Mozilla Firefox" in its title.
We expect Mozilla will remove the offending link quickly enough, but let's hope they are smart enough to modify their Community Ticker code so it doesn't happen again. If you weren't lucky to catch the comedy URL yourself, we've put the pic below.

Tools such as grep, find and awk have often come to the rescue of gleeful Bash-mongers searching for files buried beneath gigabytes of other items. But when a typical Linux distro takes up a couple of gigs of disk space, it's not hard to imagine that finding your files will only become trickier over time.
Compared with their internet brethren, today's desktop search tools can be used not only to look for the names of files on your disk, but can also perform context-sensitive searches within email archives, images, videos and music. Some tools take it a bit further and even index your browser history and bookmarks. But with so many different tools to choose from, often offering the same or similar features, just which are worth trying?
We picked out the best desktop search tools for Linux and put them through their paces - read on to find out how they fared!
(PS: if you much prefer working on the command line, don't miss our how to find files on the Linux command line tutorial!)

Over the last 12 months, netbook and mobile Linux has made massive advances in features and install base. This is primarily thanks to two netbook distributions - Moblin and Canonical's Ubuntu Netbook Remix (UNR). Both have built on the massive potential that was unlocked by the Asus Eee PC but led nowhere, as its operating system failed to inspire a new generation of Linux users.
But now technologies from Google such as Android and Chrome OS are bringing a new wave of innovation to the Linux netbook space, so we thought it was time to take a look at the contenders in the netbook and mobile distro space to see just what's going on. Which netbook distro is right for you? Do they work just as well on desktops? Are Chrome OS or Maemo real contenders? Read on to find out!
(NB: if you missed our previous articles, catch up by reading our group test of netbook distros and our guide to choosing the best Linux distro for you.)

The internet is inherently insecure. Whenever you send data across it, there is a chance that that data could be sniffed, and someone could end up with your personal data. Hopefully once you've read this article, you'll have a better understanding of how to prevent this from happening.
When data travels through the internet, it needs to pass through multiple connections to get to its final destination. Most people don't realise that the data can be read by any machine it passes through on this journey.
With the right tools, you can sniff this data yourself, and any data that passes through your network. This is because most networks actually send data intended for anyone on that network to all machines on your network, and your computer will ignore anything that's not meant for it. This is especially true for most wireless networks, even networks that are 'secured' with WEP/WPA.

Here's a quick heads-up about the latest issue of Linux Format. We're giving it a special mention here because we're expecting it to sell out quickly! Why, you ask? Well, just like every issue it's packed to the gills with Linux and free software reviews, features and guides, but this month we've gone the extra mile:
- A monster double-sided, 8GB DVD with Ubuntu 9.10 (special Linux Format remaster with 300 extra packages), Mandriva 2010 and OpenSUSE 11.2
- A free, bonus wallchart: one side is crammed with quick Linux tips, shortcuts and links, while the other side has awesome Ubuntu artwork for your wall
LXF 127 is available in UK newsagents today, and for US-based readers it should be stocked in your nearest Barnes & Noble or Borders soon!
Update: copies have already sold out at our online store, so you'll need to buy it in brick-and-mortar stores instead. Heck, buy five, put them on eBay, and make yourself a tidy profit.
Update part 2: we've got some more copies available in our online store, so grab one before they sell out again!

The Software Freedom Law Center has announced a lawsuit against 14 companies, including Best Buy, JVC and Samsung, for GPL violations relating to BusyBox, which is a GPL-licensed bundle of Unix tools. The SFLC said it "gave each defendant ample time to comply with the requirements of the license", but what do you think: is suing necessary in today's world, or does it reflect badly on the Free Software community? Moreover, should we be encouraging the naming and shaming of offenders, or does it generate bad feeling towards the GPL?
As per usual, the best comments will be used in our podcast, so please leave a name other than Anonymous Penguin, please state your view clearly, then back it up with some sort of logical reasoning.

Not all distros are made equal, particularly if you're a KDE user. KDE has had something of a rough time over the last couple of years. The transition from version 3.5 to 4.x hasn't been easy, and over this period many distributions have decided to use either Gnome or stick with KDE 3.5 as their default desktop.
But we feel KDE 4 has now matured to a point where most KDE users can safely dump their old desktop and move on to the new one. There are very few stability issues, and most of the functionality found in 3.5 has been migrated to 4.3. The question is, which Linux distro provides the best experience for KDE users?
Rather than providing simple packages for KDE, a real KDE distro is likely to include GUI refinements, usability tweaks, custom themes, artwork and a good selection of KDE applications. It's also nice when Gnome and GTK applications play happily with their KDE counterparts, especially if a compatible theme has been chosen from them both. KDE-based distros should be able to do this better than simple Gnome desktops.
So, we took eight of the top KDE-focused distros and pitched them head-to-head to find which ones really rock, and which ones just limp along with a vanilla set of packages. Read on!

It's now fair to say that the Linux desktop is at the forefront of visual effects, a cornucopia of eye-candy overflowing on to your desktop. And with a few tweaks, it can look even better.
With both Windows and OS X continually upping the ante in what the average desktop user expects from their desktop experience, it's vitally important that Linux stays ahead of the game - even if that only means turning on a genie effect for minimized applications when your friends come over, or using a more usable version of virtual desktops when you lend your machine to someone.
Adding eye candy should never be about purely cosmetic changes. Instead, it should enhance the usability of the desktop and make the average session more productive and more streamlined. We're going to show you how to do just this, and in the process we'll help you turn your Linux desktop into the envy of your proprietary OS-loving friends.

Python is a great way to make apps quickly, and what better source of data is there than the world wide web? We've already shown you how to control Digg with Python and how to create a Twitter bot in Python, and now we turn our beady eyes towards Flickr, the home of more cat photos than I Can Haz Cheezburger knows what to do with. If you want to try your hand at uploading photos to Flickr, while learning just a smidge of PyGTK along the way, this project is for you.
If you're desperate for even more things to code, don't forget our complete code projects archive is waiting for you...

Cloud computing is now firmly embedded within the IT mainstream, with companies like Amazon, Google and Microsoft offering a range of cloud services. And now you can too: in this tutorial we're going to create a cloud server using a piece of software called Tonido.
We'll set it up initially so we can access the various services from within our home network and also over the internet so we can share music and documents and remotely access a calendar, to-do list and other services. Let's go!

Is it possible to cram a whole Linux server into something the size of a plug? Apparently it is - Marvell has combined gigabit Ethernet, flash storage and an ARM CPU with a full install of Ubuntu to produce the tiniest Linux server we've seen for some time. Can you resist the power of your geek hardware lust? If not, don't read on...
