Re: MS announced ARM support for windows 8

<t>According to Microsofts demands for branding ARM based products as Win 8 compatible this will not happen.<br/> <br/> For the ARM architecture, the Microsoft document lists as a requirement that the UEFI bootloader *must* be configured in safe mode meaning it will only boot operating systems with ...

Re: repository for 'official' educational material/documentation

<t>I would say that the foundation needs some official spot where we could get started on setting up the required teaching material for the educational (and home educational) sector.<br/> <br/> My immediate thoughts are that this is mostly a documentation project. It needs to support collaborative w...

Re: Failure is not costly.

<r>Failure is highly necessary to learn, but it is also extremely important that the material and the teachers/mentors build the correct atmosphere/mindset for learning from faults.<br/> <br/> If you have anything to do with mentoring/teaching other people (and that is why you are here, right?), ple...

Re: Best first language

<t>As a long time computer geek fostered on BBC model B I am thinking that for children (starting at age 6 or so) scratch is a very nice environment. My 6 year old creates logo turtle like graphics using the graphical building blocks. The great thing is there is no need to understand english in orde...

Re: The Old Beeb and Computer Literacy.

<t>I was also a proud BBC B owner, but I did not live in the UK and had no direct benefit from the beeb being the school computer. Absolutely none of my friends had one either.<br/> <br/> Still, being the UK school computer meant there was a lot of good documentation on it, lots of in-depth articles...

Re: power RPi through the USB 2.0 port?

<t>What I have read on the net suggests the opposite. That powered USB hubs normally provide power only to downstream ports, not to the upstream (host) port.<br/> <br/> From my readings there should be a diode connecting +5V from the upstream port so that current will flow from the upstream host onl...

Re: power RPi through the USB 2.0 port?

<r>Can the RPi be powered through the USB 2.0 port? I saw a comment in the wiki that +5V from the micro USB was sent unfiltered to HDMI and USB, so I hope this means the RPi can also be powered from the ordinary USB port.<br/> <br/> The reason I ask is that a 7-port hub on DX is getting some warning...
