Re: microsoft and facebook to help teach computer science

Stating that Microsoft is to a great part responsible for the closing up of computer systems and making it harder to program, came across as rather rabid and you haven't convinced me at all that this is the case. Your statement that it isn't in the interests if MS for it's customers to be programmer...

Re: Rev2 Mounted with P5 & P6 Fitted!

Complete speculation but I believe previously they have said that the RPi's are made on sheets of 6 boards, so my guess is it is identifying which part of the sheet you RPi came from.

Re: Is 512mb a good thing?

C and assembler (and, god forbid, C++), whilst they have their place, are again, not good teaching languages. Python, Smalltalk, Logo, Ruby, Lisp/Scheme, these are good teaching languages. My opinion is that, although 512MB is an incremental step forwards in hardware capability, what the Pi needs i...

Re: Is 512mb a good thing?

In general it's fantastic news. However, if like me, you are selling pre-formatted SD cards to newbies, this is causing me a major headache and I'm struggling to explain the issue in a non-scary way. It also means that my customers have to make a 256/512 *choice* and they might not know why (so I'm...

Re: Donation to the foundation

You already ask for a donation in the trademark rules if people are making a commercial profit from the Raspberry Pi. I think everyone agrees this is more than reasonable - in fact it looks like Texy is in this position hence the question. Therefore it seems reasonable to put a button (or just a sim...

Re: ext3/4 and SD-card wear leveling

Of course all you have proved is that if you read an erased/trimmed block the SD card controller return zeros, you haven't proved whether it actually wasted time erasing them, it may just have set a flag somewhere and have code in the format:
if(blockErased) return zeroData else return blockData.

Re: confused about H264 encoding

Most doing digital TV just stream the digital TV over USB - no decoding required, if you are lucky they may strip out the parts of the stream that aren't related to the channel you are watching - this is pretty cheap and easy and no complex decoding/encoding is needed at all. Others just overwhelm t...

Re: What's the plural of Raspberry Pi.

It's inelegant because in the standard rules of English pronunciation when reading "Pis" out of context there are no rules or precedents to persuade that it should be pronounced like "Pies", instead it would almost certainly be pronounced like "Piss". The issue is Pi is a greek letter so should prob...

Re: RPi in Car: "live" image (read-only)?

I'd suggest searching google on how to create a Linux rescue or live CD image - by definitions these have to ensure nothing is written to disk. You'll probably also want to configure the fstab file to tell it to enforce readonly (ro) mounting so that the low level drivers prevent files from actually...

it would probably be possible to use a level converter with PS/2 style mice/keyboard and bit-bang the interface.
No idea whether existing drivers exist or you would have to write them from scratch as well.
