I love-love-love my new HP calculator. I haven't felt this way abaout a piece of engineering kit since I got my HP25C more than 30 years ago.

In my opinion, the HP 35s is the first calculator HP's made since the 41CV that's worthy of the name. A whole lotta love for $60!

Very inexpensive S/W tool for FIR filter design. Includes C library for implementing FIR filters.

Quoted: ScopeFIR designs Complex FIR filters using the Parks-McClellan algorithm or windowing. It can mix, scale, quantize, and edit the coefficients of the Finite-Impulse Response filter.

Cool web tool for filter calculations

Super efficient biomass stove fabricated from recycled PC parts

From an editorial in the San Jose Mercury News by a couple of university professors.

Quoted: The next wave of high-value products will require assembly at the micro and nano scales, where manual labor is no longer an option. These trends suggest enormous opportunities.

Includes a detailed discussion and analysis of current practice. PhD Dissertation by Jung-Hoon Chun.

Wired 8.04: Why the future doesn't need us.
The process of developing the underlying techniques is unstoppable because the component benefits are so compelling. The question is, can we regulate how the pieces are put together, perhaps in the same way we now attempt to regulate human genetic research?
I'm fascinated by Hillis and Kurzweil who look at silicon-based transcriptions of their humanity as an option. Even if it's impossible for someone to see its pointlessness, surely they can grasp how their new existence would become obsolete within one processor generation (3 years?). Who would care to upgrade them? Who would protect them from predation by more powerful next-generation H/W & S/W?
