Re: Availability in CANADA

When I buy online and am told it is being shipped from Canada and a Canadian warehouse , I expect that it WILL NOT BE SHIPPED FROM THE USA TO CANADA AFTER MY ORDER IS PLACED They're not made in Canada, how exactly do you expect they get to Canada? When they say "shipped from Canada", they...

Re: Parallella: A Supercomputer For Everyone

How disappointed I was when I started getting two then four core PCs, and realised that they were no faster (for almost all appllications) than before. This is true if you're hoping to get more performance out of a single application. For me, the greatest benefit of multicore has been that I can do...

Re: persistent Wrong Hash value

Are you checking the checksum of the .zip file you downloaded, or of the unzipped contents? I believe the checksum is for the .zip file.

Re: RPi as a mother board

The GPIO pins aren't fast enough to run a video card at full speed (if you were enough of an electronics wizard to get it to work in the first place).

Re: Raspberry Pi boot

The Raspberry Pi boot files are not written in ARM code, but in code specific to the GPU that is actually controlling the boot process. You won't have much luck trying to write your own as the specifications for the GPU are not public. The first stage of the process you can control is kernel.img. I ...

Re: How to find the RAM size?

Exit top by pressing Q or [ctrl]+Z . Ctrl+Z does not exit top (or any other program). It suspends the currently running command/program so you can get back to your shell prompt. Top is still there in the background, type fg to bring it back to the foreground. You may be thinking of Ctrl+C which doe...

Re: Glade on the raspberry pi

I may be mistaken, but I think you can create your Glade UI on another computer, and then transfer the .XML file that it creates to the pi and compile your application there.

Re: Naive question: Why have an sd card slot at all?

Why from a design point of view? 'There isn't any code'... or 'just because' doesnt address the question. Why design it that way? The System on a Chip (SoC) that powers the Raspberry Pi is, to my understanding, designed for mobile phones and the like. Therefore it's probably only been designed at t...

Re: Morse machine problems...

Look up the 'for' loop in Python. For example, you could do something like:

Code: Select all

for letter in string:
    print letter
This would print each letter of the string, one per line.

Re: RPi will not power on

Give it a few hours and then try again. The Pi has fuses that, when blown, take a while to restore themselves. It might just be that you gave it a power surge and blew the fuse.

Re: Pi hangs when start.elf replaced

I think a recent firmware update fixed a bug that was corrupting the boot partition when it was written to (don't quote me on that though ;) ). I did a rpi-update the other day and the process of writing the new firmware to the boot partition seemed to have corrupted it and my Pi would not boot. I j...

I don't think there's room on the Pi to drill any holes. All the mounted boards I've seen have been mounted with brackets of some sort.

Re: Minimising SD card writes

As an alternative to linking .bash_history to /dev/null, you can just set the HISTFILE shell variable (in your .bashrc file for example) to blank, which will cause Bash to not write a history file. I haven't got my Pi yet, so I don't know if distributions like Raspbian already do this, but you might...
