Re: Power supply news!

<t>Excellent decision. Most people will be able to find a micro-USB adapter, either in hand or cheaply. Or they can combine the expense of a powered USB hub and an AC adapter for the Pi with just a USB / micro-USB cable needed to serve as the power supply for the RP instead of yet another wall wart ...

Re: Clustering

<t>In terms of processing power I don't think it would be cost-effective except for educational purposes. Even if GPGPU is available (and I hope it will be) the effective processing power will be a bit over 15 GFLOPS. (60% of nominal 24 GFLOPS). The SD cards, power supply, cables and ethernet switch...

Re: Specific Software Test Cases

I hope someone will test and make sure the JVM is working properly. Some of the primary target educational languages such as Proce55ing depend on it, as well as many other things of course.

Re: What have we missed?

<t>@ vadsamoht:<br/> I was trying to make an estimate of the additional costs for the original target market, kids who don't have their own computer. Some families will have old peripherals, but USB is needed, so many of the old ones won't work, and of course many families do not have any old periph...

Re: What have we missed?

<t>We need a price on a package that actually gives all the minimum items needed for a working system. I've tried to find the cheapest credible new prices to make an estimate. (UK prices will likely be at least 30% higher, plus VAT - I cynically figure it'll be about the same number in pounds as it ...

Re: Raspberry Pi 101 (read before posting)

<t>One basic bit of information which doesn't seem to be in the FAQ or the Wiki:<br/> Will it come with an SD card?<br/> If not, how will the software be distributed, will there be an option to get an SD card with pre-loaded software and how much will it cost?<br/> In either case, how big is the cap...

Re: Shipping and Handling

<t>It seems likely to me that you'll need the capability of scaling to hundreds of thousands of units per year over the first few months, with hundreds of returns and the associated customer service needs. You can't do it yourself, and building the logistics and other capacity needed to do it in-hou...

Re: Teaching Youngsters Programming

<t>OOP shouldn't be a primary requirement. It's more of a religious precept with confusing theology than anything else. The same is true of structured programming and functional programming. Good ideas, but sometimes a GOTO or procedural bit with side effects will get the job done faster. The langua...

Re: Science and Maths programs

Do others have ideas for good educational programs to be included with Raspberry Pi? Here are two I think are indispensable: Frink http://futureboy.us/frinkdocs/ and GAViewer http://www.geometricalgebra.net/gaviewer_download.html Frink is a full-featured programming language for physical computation...

Re: What have we missed?

<t>The biggest improvement to usability for the target educational market would be a 2nd SD card slot. On the old computers that had only one floppy drive it was a pain in the butt to copy a disk. The source and destination disks would have to be shuffled several times as a block the size of free me...
