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...

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.

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...

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...

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...

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.

Please read the thread I've linked to in my last post, it's only a few pages. There are some Pis that don't boot with the latest Raspbian and Arch. One poster in my thread has just bough two Pis (2nd generation), one boots, the other one doesn't. Same SD card, with Rasbpian. It's not a hardware pro...

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...

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...

I take it a long extension cable and cable cover/gaffer tape is out of the question!? Surely there must be somewhere they plug the hover in?

Though a mobile apocalypse proof RPi cluster does sound fun

But what customer would have deliberately selected a Rev 1 board so they wouldn't have managed to clear their backlog of stock? If people did order rev 1 boards It would probably also make complications for them when they finally ran out of boards and had to substitute the 'alternative' product in. ...

My guess is that when a new delivery arrives Farnell stack the new boxes at the front of the shelf. After R2 boards were released they got a sudden increase in orders, they have now worked there way all the way through the new boxes, all the way through the updated boards and are now using the reall...

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...

The approach I took was to void the warrenty on the power supply instead and splice a usb plug onto it from a spare usb cable - safer than taking the soldering iron to the RPi

Presumably if it can produce the linux kernel which runs from bare metal (give or take a bootloader) then it can build an alternative 'kernel' running a specific bare metal application?

mole125

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.

mole125

It may not be in the datasheet but if memory serves me right some sample code has been provided, if it hasn't then isn't the details available in the kernel drivers?

That looks like it is more or less working. Thank you. Two minor comments: 1. You should probably uncheck the Item Statistics option - the author and time is present on the item anyway so I can't see what benefit it adds and looks confusing. 2. All the forum feeds have the same feed name (title=Rasp...

I've already posted the request on both the recent blog posts. RSS seems to have become a generic term for feeds even when they are Atom (at least the BBC use it that way). It would be great if they could be moved up your list - it is pretty much the only way to keep on top of what is happening on t...

<t>No email for me saying my Pi had been dispatched... but did get a nice card through the door yesterday saying it had been left at a vaguely local post office so is now sat on my desk waiting for me to work out if I can find any cables at work Think I'll choose the Pi over the email an...

<t>I'd agree with not just one language, but I don't think many MD's have actually been the janitor, the modern approach is to get some silly business degree and jump in half way up... More to the point it is better for a first language (which sadly is the case for many computer science students) to...

<t>There's various valid arguments for and against using Java to teach programming but I have to say I found that argument to be one of the weaker ones I've seen. Embedded programming is a niche, a very important niche which makes the world go round, but much of the arguments presented in...
