I knew this could be done! … Game of Thrones’ main theme played by 6 floppy drives. Enjoy.

I just came across PeerJS – Peer-to-peer JavaScript library. Great to see this kind of API available, hope we will soon see some real-world applications.
There is an interesting project for your next free weekend – fixing the ISS by inventing a solar panel positioning algorithm. Sounds fun!

An interesting read back from the year 1996 about Inferno vs. Java – http://doc.cat-v.org/inferno/historical_documents/website/infernojava
Infernos with its programming language (Limbo) seemed like such an awesome project. Why did it not take off and why do we use Java instead? I guess some concepts just come too soon, before it is their time to shine…
Finally got it working. All it needed was a 2+ GB SD card and not only 1 GB, which resulted in a restart-loop with error messages not far from “Something is broken! Panic!”.
Next on my agenda – hook up all of my 5 RPis and form a “supercomputer”!

And by the way – the user experience is ground-breaking and paradigm-shifting. The scrolling wheel works in an opposite direction! (+ some other mind blowing things)
It is finally here! My new Raspberry Pi case.

Plan 9 – distributed operating system, now ported to Raspberry Pi.

…newly on my ToDo list.
Here are a few pointers on how to make the sound work on Raspberry Pi. I’ve gathered these bits and pieces along the way of using this tiny computer.
First of all – Arch Linux for ARM (i.e. alarm) is the best distro I’ve used on RasPi so far. Lightweight, starts in just a few seconds, has a lots of packages and you can install it just the way you want. And this is also the distro for which I am writing this short How-To.
To make the system see the integrated sound card you need to load the appropriate kernel module. Like so:
sudo modprobe snd_bcm2835
To check whether it is loaded, just check the output of lsmod. The command written above has to be executed every time the system starts. To make it “stick”, add the module to the list of automatically loaded modules. That is create a new file /etc/modules-load.d/sound.conf containing just a single line:
snd-bcm2835
That’s it. The sound module should now load every time you start your RasPi.
Most of the programs will be able to output sound using Alsa. To install it, issue this command:
sudo pacman -S alsa-utils alsa-plugins alsa-lib alsa-firmware
Now you can run speaker-test and it should produce a nice white noise on your speakers.
If you want to select which sound output should be used (HDMI or analog 3.5mm jack), the command to use for Alsa and analog output is:
sudo amixer cset numid=3 1
Or substitute the last “1” for “2” if you want HDMI.
If you are getting messages like this:
alsa audio output error: cannot commit hardware parameters: Invalid argument jack audio output error: failed to connect to JACK server main audio output error: no suitable audio output module
All you have to do is fix the sound card configuration via creating a simple *.conf file: /etc/asound.conf with the following content:
pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }

Finally! Raspberry Pi with 512 MB of RAM is here, in my hands! Let the fun begin…
Finally a way to write code for those “simple” microcontrollers – in Java!
