A great read. However, I also clicked the link near the bottom about the "$35 Tablet in India" and discovered this little gem in the middle:
---While originally presented as a Linux device, the prototype on the show runs on Android (and handles the operating system "fairly smoothly," the surprised Gurus say).==
I don't think people will ever learn that Android IS Linux!

Android is Linux the way SeaMonkey is FireFox.

arcanis, you haven't read enough. android uses a *forked* version of the linux kernel, so it is not linux any more. At first, they co-operated with the kernel devs and tried to have their code included in the main-line kernel. At that time, you could check out the official kernel sources and produce an android kernel.

But, they could/would not meet the requirements of the kernel devs, so they simply forked the kernel and now make changes without any regard to the main kernel developments. You cannot take the android sources and create a linux kernel.

It has already been announced that
there won't be any Opengl accelerated drivers for raspi .
'Unlikely' according to Eben.

...but I noticed that a German guy from DirectFB is interested
in developing for raspi

this is what annoys me, no OpenGL for Rasp...

also the cost of the hdmi screen etc, you can get opengl capable android tablets for $80 now from ebay and ofc the screen is already there.

im not trying to be a wise guy here, the Rasp will bring alot of awareness from alot of people to the ARM platform, small computers and linux, thus encouraging efficient smart software that relies on good code, not hardware specs.... this is a very good thing.

its a dream of mine to like have a mini server farm, but i dont know really what way ill go, tablet or rasp. Android tablets have ethernet already there, this is important, as a server farm with only wifi would suck. Once setup im looking to learn how to run a cluster.

No OpenGL is a pain, but i never really expected the Rasp to be replacing home systems very much, but..... the way i see it is:

SERVER FTW!!!

cheapish quiet power efficient servers and you can fit 10 of them on top of your bookshelf, its freaking awesome. I already have setup cheapo tablets with debian and run game servers and fileservers etc and stream the webcam over the network, with wifi these things are portable security cameras aswell.

i havent used a Rasp yet, maybe it will impress me, maybe it wont. Whatever the case i think we will have a sweet year ahead of us messing with these things

I would love to build a Beowulf cluster with these little cards. Imagine how many you could put into a PC case with a little creative alteration! Too bad they do not have gigabyte NICs though

i read on the their forums that a cluster (though there's a lot of interest in it) isn't very price feasible. after a certain amount, you could probably just buy a better computer for the same price.

Haha we will end up with one puppy for old computers.
One for RaspberryPi and one that is a forked Android that
can make use of Android apps. Would google allow that?
Most likely not?

What about that WebOS that they told us they would allow to be
open for devs to use? Would that one work on same hardware
as Android do? That would be something interesting then maybe

actually that is pretty much the status quo... Bsd license and such... Thus the fragmentation criticisms... But puppy can do better than that anyways, we have our own fragmentation for a reason.

Guys . . . updates

So desperate to get their hands on it collector geeks are offering £2500 for the first Rpi (as of writing)
http://www.ebay.co.uk/sch/raspberry_pi/m.html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p3686

Mass availability is expected Feb 2012 (not long now . . .)

I love the server cluster ideas. Cool

Personally I have two projects. A Raspberry Pi powered shrine
http://www.murga-linux.com/puppy/viewtopic.php?p=167557#167557
and a portable time and dimensional communicator Embarassed
. . . and I will be using Puppy for both.

I am also keen on the educational potential and am working on learning pharo
http://www.pharo-project.org/home
and developing a version of ASQ for under fives

Since I am considering a mobo upgrade, I revisited the cluster VS multicore processor issue and have decided to get a motherboard that is a bit older. Perhaps quad core at the most. The reason for this is from what I can determine, there are really not huge gains in multIcore or distributed processing unless you are using applications designed to take advantage of this functionality. It would seem that the old rule of adding as much RAM as you can might still be more effective.

im wanting to learn cluster things for the sake of learning something ive always wanted to know about. I wonder if mixed cpu architectures cluster, ie x86 and ARM will work?

10x rasp. @ $25ea = $250.

yeah ill spend a 3rd of my 2 weekly pension on a 10 system cluster for the giggles.

I'm thinking that the '86 mix is probably feasible. Off the top of my head, I would think that you would need a master unit to tie in and control all the nodes (raspberry cards) This controller as master in a master/slave configuration would probably be more efficient as a stand-alone computer because it might be better for the controlling PC to have more RAM and CPU power than the raspberry pi nodes which are the actual cluster. Not to mention, that at least one part of the system should have a hard drive and CD-ROM.
I am also sorely tempted by the 250 for 10 cost. The nice thing about these little jewels is that they can be stacked in a small space. If I succumb to my impulses, I would most likely start with two 'pis and build from there, adding a node as my budget plan allows.
