Quake III bounty: we have a winner!

At the end of February, Broadcom announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack for the BCM21553 cellphone chip. To celebrate, we offered a $10k prize to the first person to port this codebase to the BCM2835 application processor that sits at the heart of the Raspberry Pi, and to get Quake 3 (which already runs on the Pi) running on the newly open ARM driver, rather on the closed-source VPU driver. Our hope was that the ported driver would be a helpful reference for anyone working on a Mesa / Gallium3D driver for VideoCore IV

A birthday present from Broadcom

Two years ago today*, the Raspberry Pi Model B went on sale, selling 100,000 units on the first day. Since then, over 2.5 million Raspberry Pis have found homes with hobbyists, children and professional engineers around the world. Each Pi in this first pallet now has over 1250 friends

More on Raspberry Pi in Africa

One of the biggest (and nicest) surprises for us over the last two years has been the Raspberry Pi project’s popularity outside the UK. Over three quarters of our sales are now to overseas customers, and while the US and mainland Europe are our largest markets (with honorable mentions to Australia, New Zealand and Japan), there’s also been a lot of interest from the developing world.

Modeling Physics with the Wolfram Language

Here’s another guest post from Allison Taylor at Wolfram Research. Today we’re looking at how to build simple physics models using the Wolfram Language If you’ve taken any introductory physics course, you’ve learned about Newtonian mechanics—conservation of energy and momentum, friction, harmonic motion, and so on. Idealized, classical motion can be broken down into a series of simple equations based on position, acceleration, and velocity.

Test Tim’s NuScratch alpha

Over the last year, we’ve seen big improvements in Scratch performance on the Pi. To date these have resulted from tweaks to the Scratch codebase and the addition of ARMv6-optimized blitting routines to the Squeak Smalltalk VM on which it runs
