One of my aims for this year is to learn the Python programming language. Why? Well it seems to be cropping up all over the place. If you own a Linux machine or an Apple Mac, chances are it is already installed. Google recently made it the primary language for their AppEngine platform. The design ethos behind it is very appealing, a down to business approach to programming that dispenses with needing lots and lots of code and allows the developer to ulitlise powerful libraries to get the job done. Python code can be run on many different devices, and it is possible to use it to develop desktop, server and web applications. Now it can also be used to develop applications for mobile phones. This is very appealing to me as a developer as it takes time to master a new skill and I would rather that skill provides a lot of flexibility and the chance to get involved in a wide variety of challenges.

Something we do have a wide choice of in Ubuntu Linux (and on many other Linux platforms) is virtualisation software. Previously in this blog I've covered VirtualBox, which was recently acquired by Sun Microsystems. A new version of this software is out, but unfortunately the download repositories have been disabled and the downloads moved to an old fashioned manual download and install model thanks to "U.S. export regulations". I hope Sun sort this out soon. Another option though has been quietly developing and as available in (K)Ubuntu 8.10. The Kernel-based Virtual Machine is an an open source option to run virtual machines on your computer which can benefit from hardware acceleration many many modern CPUs to achieve near-native speeds for the guest images. The user friendliness of this software has been greatly improved through the addition of Virt-Manager, a GUI front end for KVM which means that you don't have to use the command line anymore to set up, monitor and run your virtual machines. I took this software out for a test drive by making a virtual machine that can run Ubuntu 8.04 (32 bit) on my Kubuntu 8.04 (64 bit) system, you could of course also have Microsoft Windows as a guest, the software emulates an entire machine.

Along with many of my OU colleagues, I have been using Twitter to regularly post my 140 character thoughts and share them with people who follow me. It has become a very popular service, and despite the simple nature of its core service all sorts of innovative add-ons have been dreamt of to enhance its functionality, Twitterholics gives a good sense of what is being developed. Twitter can be updated through its website or an increasing number of clients that are being developed for it. One of these clients is KDE Twitter, which I first saw on a screenshot on the Kubuntu website, but had a bit of trouble it tracking down. KDE Twitter is a Plasmoid, a widget that can be added to the KDE4 desktop.

I've got the new Kubuntu 8.04 KDE4 Remix running now on my laptop and it is looking really good. I really like the new visual design and it is great that the Kubuntu project team made a release featuring KDE4 available on top of everything else they have had to do to get the main release of Kubuntu out. Up to now I have been running KDE3 and experimenting a bit with KDE4 on a virtual machine, but now I'm making the move full time. I don't know yet if that will prove a good decision while KDE4 is so young, it was only released in January 2008, but it is easy enough to swap desktop system on an Ubuntu distribution so I thought it was worth gaining that "bit of an edge" and going with the latest desktop experience that is available on Linux. The Ubuntu distributions always show very significant progress on every new release, and 8.04 has followed this trend and I'm finding it very pleasant to use.

Congratulations to the Ubuntu community on the release of Ubuntu 8.04! I am currently downloading a copy of Kubuntu 8.04 KDE4 Remix and preparing to make a jump from KDE3 to 4, which should give a modern looking computing experience anyway. I've been playing with the beta version of the Remix CD for a while now, and KDE4 seems to have improved quite a lot since I first blogged about it back in January. I'll about the experience of installing it on my laptop in the next few days, and since seeing this video on YouTube I'm tempted to install it on my Asus EEE PC as well! Ubuntu is a project I much admire, the name is an African term for "humanity to others", a concept they bring right into their community through the use of a Code of Conduct which encourages participants to treat each other with respect. This has resulted in an atmosphere on sites related to their project, for example the Ubuntu Forums, which I think is quite welcoming to people.

I've just been installing the new Kubuntu KDE4 Remix Beta on an old Acer L100 Media Centre using the Alternative Install CD (so I can do a text mode install) as I only have an old CRT TV attached to it. When I tried to boot from the CD it looked like the installer picked a display mode that didn't work with the TV as the picture lost stability and was unviewable. I couldn't find the usual options to change the screen mode, but found that this worked to override the screen mode:

Up to now the computing experience has been divided into two - online and offline. Being online means using sites through a web browser, offline means working with different applications, mostly designed to work with documents not stored on the Internet, but instead on local file systems. However, changes changes in the way we communicate and work are starting to make this arrangement look creaky and old fashioned so thoughts have turned to how to integrate these two worlds.

As with previous blog posts on the subject of virtualisation, I used VirtualBox to run an image of Windows Server 2008 Standard Edition(tm) on Kubuntu 7.10. You will need a fairly powerful machine with a lot of free hard disk space and free RAM. I set aside 15GB of hard disk space for the image and 1GB of RAM to be dedicated to the virtual machine.

You have probably already heard of the One Laptop Per Child Project, which aims to equip children in developing nations with low cost laptops to aid their education. The XO-1 is the first machine to be made by this project, and is very innovative in both hardware and software design. Getting your hands on one of these machines is quite difficult, especially if you don't live in North America, but what you can do is get hold of an image of the machine's operating system and run it inside a virtual machine.
