1275: Arduino IDE on amd64
The compiled packages available at arduino.cc works out of the box only for 32-bit architecture. For 64 bit you have two options
1. Download the normal package and do a small tweaking
Instructions for the same are available here. The explanation is for Gutsy, Hardy etc. (So they obviously work for the true-blooded Debian systems) Effectively just a simple modification to use system library version of librxtx rather than the packaged one. I am not repeating the steps in the hope that the site would be up for a long time to come (technology has a short shelf life anyway)
2. Check out the trunk from svn and build
I prefer this solution, not only due to my great love for svn trunks, but also due to the fact that you are more upto date in terms of developments, and it somehow feels like a purer way of doing things. The building instructions are here.
and then simply build.
Once you have the ide up and running things are relatively simple. Read about the already intuitive ide elements if you want, Blink a few times ( Arduino Hello World) and go on to further adventures (ok. guided tours).

sudo aptitude install sun-java5-jre sun-java5-jdk sun-java5-bin unzip zip gcc-avr avr-libc (install the necessary packages)
svn co svn://svn.berlios.de/arduino/trunk (check out the trunk.. not a small download ..really)
and then simply build.

1272: Diecimila
Finally, arduino is here after 15 days from the order( around 4 USD postal charge). Seems like postal service is not that bad after all .
For those who haven't yet been bored by my arduino references, well Diecimila is a microcontroller board with ATMega 168, and a USB Interface which makes microcontroller programming really easy. Effectively you can use Arduino as a small brain for anyTHING you want to build. The full set of functionality is available here . I hope to move on to/make Sanguino maybe in January 2009 ( around week 1285).
Though actual tinkering would require a bit of electronic minutiae purchase in my dear town. Just setting up basic infrastructure : avr-gcc , arduino ide ( :( a bit of java lurking around there, but not much of a direct issue i hope) USB Interfacing to electronic boards is really neat I guess, considering the fact that my laptop doesn't have a serial port. My megalith of a desktop does ( as an add-on), but in effect USB sounds like the future, or maybe I am already in the past with bluetooth and other wireless interfaces being the present.
For starters there is a whole set of interesting instructables at instructables.com . And well in the end there will always be reprap. But as you can see I am pretty far away from a self-replicating rapid prototyper.
If you think Diecimila sounds like a greek goddess or demon or something ( I thought so :P) well it is just 10k in Italian.

I really need to start coding on constraint satisfaction (brl-cad) more regularly. Very few changes since gsoc.

1279 : EDA & Molecular Visualization
Electronic Desgin Automation is indeed a vast and very fruitful field to say the least. Schematic diagram generation and PCB artwork forms a very small part of it. I was particularly impressed by the ease of use of kicad. Though I am practically more inclined towards Floorplanning ( considering my architectural backgrounds , interest in constraints, 2 gsocs in similar fields etc.) most aspects of EDA are quite inviting. Though i toyed with gEDA sometime back it never really went anywhere. Hopefully with the "more intuitive" kicad, maybe random walks would end somewhere. ( Don't laugh at the screenshot .. probably the most terrible rs232 :) and an example of a particularly large hole in the PCB :D )
Who doesn't like visualizing molecules ? If the representation looks artistically intricate like that of proteins, it hardly takes a push to try things out. I have always been impressed by the amount of open information availability in the field of genetic and protein related studies. So a book like Branden & Tooze + www = roaming around in the molecular world ( well an artistic representation of it .. blah) I have almost always used only rasmol. But I recently shifted pymol and it has been quite a wonderful experience. It is somehow much more intutive. In the picture above, the molecule on the left is Haemoglobin A ( with its characteristic Iron complexes) and the one on right is Seal Myoglobin.I have only reached Chapter 3 (alpha-domain protein structures) of B&T, but it seems like it is going to be on the top of my reading list. On a connected note , The crystal structure (3.2 A) of mammalian Fatty Acid Synthase is on Septemeber's Science cover.

On a followup note seems like Techsouls is not working. So waiting to order arduino via sparkfun
as soon as gsoc money comes to the ge corporate card which i finally got unlocked today.
