Raspberry Pi, an innovative $35 GNU/Linux box in a tiny package, launched yesterday — sort of. Demand was so hot that all the company’s retail partners collapsed under load. From Ars Technica’s Ryan Paul:
The product is a bare board with a 700MHz ARM11 CPU and 256MB of RAM. It’s roughly the size of a deck of playing cards and has a powerful GPU that is reportedly competitive with that of modern smartphones. Developer prototypes of the product have been shown running impressive graphics demos and decoding high-definition video…
At the time of publication, the Farnell website is still spitting errors. The RS site has been partially restored and is intermittently available, but isn’t currently allowing users to purchase the Raspberry Pi. Instead, it displays a screen where users can register to express their interest in the product. The Raspberry Pi foundation managed to withstand the traffic by temporarily replacing the contents of its official website with a static page.
Alongside the launch, the Raspberry Pi foundation also announced that the cheaper $25 model, which will be launched at an undisclosed future date, got a spec bump and will have 256MB of RAM, just like the $35 model. The $25 board was originally expected to have only 128MB of RAM. The cheaper model will still lack several of the features found in the $35 model, such as the built-in ethernet controller.

Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as:
- Finding out bottlenecks.
- Disk (storage) bottlenecks.
- CPU and memory bottlenecks.
- Network bottlenecks.
You may have last seen gOS, the free, Ubuntu-based Linux distribution, touted here as a way to revive an old PC with a webapp focus. Now there’s three flavors of gOS available, including a ‘Space’ release that was designed with a Mac-like slickness to its interface, and a lot of MySpace functionality thrown in, on top of all the other Google, Facebook, and other link-ups. ‘Space’ ups the hardware demands from the standard gOS (to about the modern Ubuntu requirements); if you’re running older stock or just like the original interface, it’s still offered as ‘gOS Rocket E,’ or the GNOME-based ‘gOS Rocket G’ for Ubuntu fans. Live CDs/DVDs are offered for each flavor, so it’s free to take a look. Photo by thinbegin.
