"Rarely I'll throw everything out and start over". That isn't incremental design. You don't do that - or if you have you haven't talked about it. I've commented on this before. > Some big companies stick to tweaking what they know, and get crushed > by upstarts in dorm rooms. > > Some big companies have futurists and fellows whose job is to consider > possibilities.

ASML was a spin-off from Philips, and took their human factors department with them. I applied for one job at ASML and made it to interview, but didn't seem to fit the pattern that their personnel officers expected, > I like to imagine planting a grenade inside my brain and blowing bits > all over the possible solution space, to start a zillion parallel > processors.

They sell expertise, and planting a grenade inside an expert's brain would destroy that expertise.

If you know of a solution that will work, you'd be mad not to use it. I had a good idea in 1978 that a programmable logic device to make it practical. I got my hands on one in 1993 and it ended up in Sloman A.W., Buggs P., Molloy J., and Stewart D. “A microcontroller-based driver to stabilise the temperature of an optical stage to 1mK in the range 4C to 38C, using a Peltier heat pump and a thermistor sensor” Measurement Science and Technology, 7 1653-64 (1996) >> It's still a serial process.

And some people think that you confuse tinkering with a circuit with circuit design. Somebody thinks that a two-transistor emitter-coupled monostable is a "horrendous mess" can expect to earn that kind of reputation. -- Bill Sloman, Sydney -- This email has been checked for viruses by Norton antivirus software. www.norton.com
