Back in 2007, US researchers have simulated half a virtual brain of a mouse on a supercomputer. Interestingly, Ray Kurzweil, in his 2005 book “The Singularity is Near“, accurately predicted the amount of computing power necessary for that scientific achievement.
What’s really interesting is the prediction that he made for 2013. Check this graphic:
I know this is old news1, but I guess it’s worth the consideration: asteroid 2011 AG5, an asteroid roughly the size of a football stadium, is thought to be in a (albeit improbable) collision course to Earth.

Continuing the work with analog sensors on the Raspberry Pi, I decided to test the PulseSensor‘s behavior in building a pulse sensing application. The Pulse Sensor is a well-designed plug-and-play heart-rate sensor for Arduino but considering that it’s a simple analog sensor that sends values between 0 and 1023, it’s easy enough to use with the MCP3008 ADC on the RPi.
However, the use of the Web Audio API (I didn’t want to use MP3 or WAV) for this end proved somehow useless mainly because the sounds it generates are only comparable to those of the good old days of dial-up connections. Moreover, the API is only available (for now) in Google Chrome and Mac OS X’s Safari’s latest version.
Perhaps, in the future, I’ll change it once there’s some more interesting way of doing that and that works across more browsers.
So, for now, enjoy only the visual aspect of the game.
Remember when I wrote about the “magic dust”, a vision of the possible future of nano-technology? Well, it seems that this kind of innovation (although not from a nano-technology point of view) will be available sooner than I expected, with the arrival of a new spray containing neonatal cells that can help skin heal faster.
As usual, the future looks fascinating.
