Raspberry Pi

Looks interesting!
However, one thing I don't like is that there already seems to be two versions of it, fixed platforms should have fixed configs so you can code for one directly without worrying if it runs on another config or not...

The other issue is that it's running Linux, having a multitasking OS really kills any code-to-the-metal projects.

It's too bad, I'd love to have a fixed, fast, modern platform where I still can be 100% sure that the code running, cycle by cycle is only my code and not some OS crap stealing valuable time...

Sdw you can always code your crappy OS. Although you would loose all the closed GPU libs.

Or use something like RTEMS. (Apparently it's what Milkymist ships with, which is the first thing that sprang to mind as a 'fixed, fast, modern platform')

...and any OS with a name that used to stand for "Real-Time Executive for Missile Systems" gets automatic awesome points.

There will be two models of the Raspberry Pi, model A and model B. Model A will cost about $25 and model B $35. Model A will ship with 128MB of SDRAM, while model B will have 256MB of SDRAM. A USB wi-fi dongle can be added to support wireless networking and model B will include an Ethernet controller.

Well I was considering installing debian on my moms old computer, but this looks like a much better (and faster) option for a home server :)

no realtime clock on it. As a very old amigian, I know the importance of damn clock. They should stick one on it.

ref: In the age of internet and NTP, this is a non-issue ... for the Model B, at least.

And now it seems it's finally on the factory. 10 000 units in the next 3 weeks or something.

they're already on ebay actually. Just not at £15 ;)

It also got an awesome breakout and I/O board: Gertboard
For 35$ this is an awesome platform!

Something similar I'm currently experimenting with is IOIO for Android. Connects analog, digital and PWM I/Os via USB or Bluetooth to Android systems via a simple library. It also has beta-support foor Google's Open Accessory (ADK) protocol, but is only 50$ instead of the 150-200$ Google kits.

would be nice as a video box to hook up to tv also :)

I'll definitely be getting one, I just hope the GPU is not total garbage.
parcelshit: It's capable of both Full HD and running Quake 3.

Does anyone know how you access the GPU? Through OpenGL I guess? Maybe OpenGL ES? I'm just wondering since the open source Linux graphics drivers doesn't support either OpenGL 3 or 4 which is a major pain in the ass since OpenGL 2 is vastly outdated.

paldepind: OpenGL ES 2.0

Other interesting rumors floating around are RiscOS and XMBC support. Waiting for the damn web store to start selling these already! :)

XBMC, to be exact.

paldepind, Quake 3 is not really a challenging benchmark for a modern embedded GPU...
AROS would fit greatly on Raspberry Pi

blueghost: Thanks!

parcelshit: I don't know anything about how impressive Q3 is or isn't. I was only mentioning it to give an idea of how fast/slow it is.
