If you have more than one computer running Ubuntu (or Debian), or maybe you are experimenting with different installations of Ubuntu using something like VirtualBox, you might find yourself using a lot of bandwidth and time when downloading packages from the Internet to update or add capabilities to your machine. By default each installation of Ubuntu will go directly to the Ubuntu download servers to get packages, producing a situation where you are downloading the same file multiple times through your connection to your ISP. There is an alternative to this situation though, you can download the packages through a host on your own network that will act as a cache. The next time any machine wanting that file requires it, the cache will serve its own copy, instead of having to download it again. This is a lot quicker, as the speed in your internal network will be much higher than the speed of the connection to your ISP, it is also a great bonus if you have maximum download allowances as part of your Internet connectivity package. Setting this up is not too difficult, thanks to a program called Apt-cacher.

Asus have released a free SDK for their popular EEE PC. The SDK also includes a facilty to generate a VMWare image of an EEE from the support DVD supplied with the machine or with an image of that DVD. The SDK and an image of the support DVD can be downloaded from: http://sourceforge.net/project/showfiles.php?group_id=215613. As the Asus EEE PC uses the Linux operating system an SDK is not absolutely necessary for software development as everything you need could probably be obtained within your favourite distribution, so the emphasis in this SDK might be a little bit different to what you are used to. What Asus have supplied is a complete environment to create applications, so the SDK DVD is an installer disk for Xandros Open Circulation Edition (a free version of their product) which has the Eclipse IDE built into it, some tools for developing with Qt, and a Xandros produced package maker. So the idea is you can burn the image to a DVD and boot your computer with that and then you can get straight on with some development. You can also run the SDK in a virtual machine as well.
