Cool Memories is the other side of America, the disillusioned side, presented in the form of a diary, though not in the classical sense.
His new book is about cats, Foucault, Alfa-Romeos, leukaemia, Catholicism, the Berlin Wall, mattresses, Laurent Fabius, John-Paul II, roses, Antarctica, Lech Walesa, mud wrestling, Zinoviev, porn films, snow, feminism, Rio, Jacques Lacan, Stevie Wonder, Palermo, DNA and terrorism.
I'm trying to grasp a world in all its silences and its brutality. Can you grasp a world when you're no longer tied to it by some kind of ideological enthusiasm, or by traditional passions? Can things "tell" themselves through stories and fragments? THese are some of the questions posed in a book which may seem melancholic. But then I think almost every diary is melancholic. Melancholy is in the very state of things.

FreeIMU
FreeIMU: designing a free (as in speech) 9 DOM/DOF MARG IMU

UPDATE 2011-02-10: Check out FreeIMU project page for all the informations about FreeIMU!
In the past months I worked a lot on accelerometers, gyroscopes and digital compasses. I'm now pretty intimate with the ADXL345, the ITG3200 and the HMC5843.
I've been able to design and construct homebrew DIY breakout board PCBs for all of them (ADXL345 and ITG3200) and to create a nice library to use them which also implement a great sensor fusion algorithm capable of running on the Arduino without problems.
I'm now making the next step. Let me introduce FreeIMU.
FreeIMU is a 9 DOM/DOF MARG IMU based on the ADXL345, the ITG3200 and the HMC5843. As this is part of my Master of Science Project and that I completely share the openness of projects like Arduino, FreeIMU will be completely open: all the designs will be released under a Creative Commons Attribution-ShareAlike 3.0 Unported while all the software will be release under GNU GPL v3.
As my background is in computer science, I'm quite self-taught in PCB designs and in electronics in general. So, I'm now seeking review for FreeIMU's schematics and PCB designs. If you have experience working with IMUs, designing PCBs or circuits and you would like to contribute to a free project please have a look at the designs and feel free to comment it.
I'm using kicad as schematics and PCB editing software. It's free (as in speech) software and, once you get around its glitches, it works really well. Using non-libre software like EAGLE to design a free hardware like FreeIMU would have been simply senseless.
Note: I'm using a nightly updated version of Kicad, so if you have problems opening the files you might need to update your version of Kicad.
So, you'll find the current Kicad based sources of FreeIMU in the attachments to this page just below. You'll also need a library of components which I also attach here. For your convenience I attach also a pdf version of the schematics.
I plan to submit FreeIMU to DorkbotPDX PCB Order of the 13th December to have it constructed. I currently don't see this as a commercial project but if someone is interested in FreeIMU I could sell a couple of boards.
Ok, so.. looking forward to hear your comments. Thanks!

Interview: James Sterrett, Professional Wargamer | Rock, Paper, Shotgun: "Finally, the official AMSO (Army Modeling & Simulation Office) definitions turn out to work remarkably well. Paraphrasing, AMSO defines a model as a mathematical description, a simulation as a model iterated over time, and a game as a simulation with goals and decisions. By this definition, the troops-on-the-ground exercises run at the National Training Center are games – and the military used to call them “wargames” – and Candyland is not a game. (Candyland is a simulation: Candyland derives from Snakes & Ladders, and Snakes & Ladders derives from an Indian game in which the chutes are vices, the ladders are virtues, and the goal is Buddhist Enlightenment… a simulation of the Buddhist worldview.) However, while these definitions are logical, they don’t do much to handle people complaining."

We Lost
""Well, we lost. Now is not about him anymore. His next four years are not about him as, when he finishes, he will be automatically retired and off the politics, and going into history. Now is about America.
Someone said, I don't remember who, that the first four years are about reelection, the second term is about legacy.

Someone said, I don't remember who, that the first four years are about reelection, the second term is about legacy.
I am a Republican, since before I was born. I believe that government must
be minimum, that we shouldn't have any kind of welfare or safety net, I believe that people that cannot pay for their own food, their own housing, their own healthcare, they shouldn't have it for free. Was that way when capitalism began, and was that way when it worked: only the strongest would survive. I am far right, a Tea Party militia commander, and my political views are totally opposite of the President Obama.
But, I am American, and I am tired of fighting my brothers and sisters, my fellow Americans, no matter if they are red or blue.So, President Obama, this time, I won't be a sore loser. Our country needs more from me. Our country needs us to be working together for the good of us all. We need to recover. Because we need America back. And the world also needs America strong, as China is growing its tentacles over Africa, South America, and now Europe, through Portugal.That way, I say: President Obama, I will oppose you, yes, because I can't agree with your political views. But, that will be a different kind of opposition. The give-no-quarter politics will change, and I am here to cooperate with you, if you give yourself to the fight for America reconstruction. I will be waiting, President. Do what is best for my beloved America, and I will be right by your side, fighting alongside you. We need you to be stronger and decisive or we will die as a country.""
