Re: turn on script with ftp holding

It looks like you will need to have your Pi running a program that receives messages and stores them until it can forward them to the FTP server. This should be as simple as the typical "Echo Server" code you find in tutorials on TCP communication. But instead of echoing right away, you wait until t...

Re: raspberrypi-kernel-devel

If you want to compile a kernel for the Pi your best bet is to just download the source directly from the git repos.

http://elinux.org/Rpi_kernel_compilation has all the info on how to pull the source and compile it.

RPi User Groups and PGP Keysigning Party

Today I was thinking about security and decided to update my PGP Key to a better layout. That got me thinking that since there are lots of RPi User Groups popping up, one OT activity all the groups could do is have a Key Singing Party.

Re: NEEDED: Arch AVR-GCC Package/Information

One of the easiest ways to build a GCC cross target is to use crosstool-NG.

Call the manufacturer's customer service and give them your order number. That way you know that someone has modified your account rather than just hoping someone reads the emails that get sent to whatever the automated confirmations are sent.

Re: Best File System for Flash

What you are looking for is a non-journaling file system like ext2.

What kind of writing are you expecting? I think that you might ...

You could attempt to build a low power cut off circuit that would regulate the connection between the Pi and the battery. Using a 555 Timer you can create a switch that goes Vcc or Gnd based on the difference between an input voltage and a reference. The reference voltage will be the difficult part ...
