Raspberry Pi now with 512MB RAM, other random links…

Earlier on today, the Raspberry Pi Foundation announced that the Model B will now be shipping with 512Mb RAM as standard, with no price change. I posted the link up on Hacker News and its caused quite a lot of happy people!

So, with the news of extra RAM, its started making me think of more things the Pi could be used for…

  • An Austrian hosting company are offering free Co-Location for Raspberry Pis with a 100Mb/s uplink and 100Gb bandwidth! FREE! with 512Mb RAM (or even 256Mb RAM) thats enough for a small site. or even a medium site (like this one) running statically.
  • Since the Pi can connect to the internet using 3G, you could install a copy of Squid and use an SSH tunnel back to your main office or home, have have multiple levels of caching going on… It would also secure your browsing.
  • Sending SMS messages though the Raspberry Pi could be useful for sending diagnostic info if the device is remote…
  • [XBMC on the Raspberry Pi] would make your media center a lot smaller, use less power, etc.

just a note on the idea of using 3G and Squid for the Pi… This is something i am interested in, so its something i want to start playing with. The idea would be as follows:

  • have a linux box in house with Squid and SSH enabled, and port forward SSH to the linux box.
  • tell the pi, on boot, to try and connect to a 3G connection.
  • once connection is live, connect to SSH tunnel
  • Squid should already be configued to load and use the upstream Squid box as an upstream cache
  • local squid should use some storage on either USB or SD for local cache

Also, using something like WANProxy on both ends should make things faster also… Having the Pi, a 3G modem, USB key (optional) and a battery pack, all in a small box, with a Wifi Adapter, should give you a faster mobile internet connection… And if you could get 2 or more 3G modems (using a Powered USB Hub of some sort), you could do load balancing…
