Re: if it legal to sell pi rom?

By "rom" do you mean SD card?
As long as you abide by http://www.raspberrypi.org/help/faqs/ and http://www.raspberrypi.org/trademark-rules/ and e.g. http://www.gnu.org/copyleft/gpl.html you should be fine.

Lots of 3rd-party Pi shops already sell pre-flashed SD cards for example.

Re: Simulating keyboard events (?) in Python

I see, I thought that was probably what you meant. I just think it's wasteful to type 'uinput.KEY_x', when I could keep re-declaring the tuple like this: variables = [30, 46, etc] tuple = (1, variables[x]) device.emit_click(tuple) Which works. Sure, it's harder to keep track of which number means w...

Re: RP used as Linux PC and Router?

Yup, no reason why it wouldn't work.

But in practical terms, buying a small standalone wireless router may well be cheaper, faster, and easier to set-up :|

Re: How to rotate by 90° Wheezy-lxde ?

It's much easier than all that. Simply set the display_rotate option as appropriate in config.txt on the first partition of your SD card. This takes effect at the 'firmware' level, no messing about in Linux or XWindows necessary :D

Re: Will I Overwrite by OpenElect Installation?

Dougie is right 8-) NOOBS itself will be on the partition 1 of the card, OpenELEC will be on partitions 5 and 6 of the card, and Pidora will be on partitions 7 and 8. Using the NOOBS boot menu simply chooses between booting the "real OS" from either partition 5 or partition 7. The only way to overwr...

Re: Performance problem

Maybe two of your Pis have slow SD cards which can't keep up with the write-rate? :?
Are all your Pis similar ages? The same Models (A/B/B+), same revisions?
Have you got the same GPU-memory-split on each Pi?

It's probably theoretically possible to learn ARM assembly without a board, but I'd expect it to be very difficult without a board that you can practise writing programs for.

In Python, a lookup table is typically implemented with a dictionary, which is something slightly different to a 2D list ;)

Re: The Raspberry Pi Model B+ Q&A thread

The camera firmware (running on the GPU) still uses I2C-0 on the B+ (same as on the B) but it uses GPIOs 28/29 to talk to the camera over I2C-0, rather than GPIOs 0/1. But this is all buried away deep inside the GPU firmware (i.e. not accessible from the Linux / CPU side), so is nothing you need to ...

Wow, "Fatal: Bad FAT: unterminated chain for \OS\ARCH\SLIDES~1." is certainly an error I've not seen before :o

Do you always get the same error every time, even after using the SDFormatter option? Have you used H2testw to check that your SD card isn't faulty?
