The Raspberry Pi

I received my device yesterday and spent the entire day fiddling, adjusting the settings and installing things. Being new to Linux I struggled through out the day trying to get the device to run a Minecraft server that I could play on with my friends, while not having to pay a fortune on electricity when leaving my laptop on.

I only found one java run time environment that I could get to download on the device through the package manager. I used 'apt-get openjdk-7-jre'. I am using the Raspian Wheezy Armel image, I think this is compatible with java? Please correct me if I am wrong, in the comments below. In the end I managed to get a somewhat 'run-able' server, having to fully overclock the device to the maximum 1 GHz CPU clock ("Turbo mode"), this still however used all the device's processing power, while constantly warning me "Has the system time changed or is the server overloaded" every 30 seconds when idle. I am now looking for an alternatively coded server client to use.

With all that out of the way I really want to shout my praises to this device. I haven't used the I/O pins yet but I think that the idea to implement them in this device was amazing. The fact that I could get my device to turn the lights on in my house is really neat. When the camera device is released I plan to create a program to turn the Raspberry Pi into a CCTV camera and controller, giving me a live stream of the outside of my house. The only annoyance I have found is the fact there is no power switch, but it cost me £22 from eBay so I am not complaining.

To conclude, I am really glad I got this device and hope to post more interesting news, its possible uses and compatible programs to use in the future. Also I will be showing you some of my creations as soon as I understand how to make them.
