Comment Good people do this anyway (Score 2) 141

Creative people are curious, and anybody who is any good has toys to play with and side projects on the go. A good manager will encourage a bit of goofing off...sorry, personal research. Good people do so anyway, and if it's on company time, the company may be able to make some money out of it.

Not every side project will be a winner, but if you don't try, you will never know. One of mine got a security guard fired. Another became a key test tool. Another looked like a good way for the company to make lots of money until our marketing person screwed it up. :-(

Comment Is this progress? (Score 4, Insightful) 170

Sorry, but I can't accept this being progress toward a proof.

Consider Fermat's Last Theorem. Proving it for any particular exponent is doable. Mathematicians had proved it for various sets of exponents (Sophie Germain, Wieferich, etc.). But the proof for all exponents was based on completely different mathematics (Elliptic curves/modular forms, Taniyama-Shimura, Wiles) and didn't look like anything that had come before.

Comment I don't get it... :-( (Score 1) 239

I don't get the point of a hybrid airplane in the first place.

Hybrid cars work well in stop-and-go city traffic (almost all the taxis here are hybrids, as are all the new transit buses), but drone along on their engines on the highway like any other car.

An airplane engine runs at constant speed, constant load, usually a fairly high percentage of its maximum output (65 to 75%). I see no advantage here.

Am I missing something?

Comment Good view from home! (Score 3, Interesting) 143

I live in southwestern British Columbia, Canada, and not only will we have a good view (egress is just after sunset), the weather prospects are decent. My mylar filter is ready to go on my Takahashi, so is my Coronado PST, bought on the way to the airport to observe the 2006 eclipse in Turkey.

In 2004 I looked at creative places I might go to see the transit, and one candidate was Inuvik, thanks to the midnight sun. Until I looked at the weather prospects there, and concluded it wasn't going to happen. I got skunked by the 2010 eclipse from Mangaia in the Cook Islands, nice sunny weather the entire time, except at the time of the eclipse. Nice place, otherwise.

The nonsense about electric cars is no different. It's just attempts by the lobbying department of interested automobile makers (the ones who aren't adapting to the 21st century) using bribed republicans and regulatory capture to try to create artificial barriers to adoption against their competition.

A very long time ago steam was the proven technology, electric cars were considered quiet and civilized, and gas engine cars were the noisy, dangerous, smelly upstarts. The gas engine car manufacturers engaged in a major FUD campaign against electric cars. They were dangerous! They were so quiet you couldn't hear them coming...

We have an active electric vehicle club here in Vancouver. The loudest noise their best conversions make is the whirr of the tires, sometimes with a slight groan from their power controllers. They have a 1912 Detroit electric car, and it's almost completely silent.

Our bus system has one of the larger fleets of electric trolley buses in the western world. They too are very quiet, but people get used to looking for them before crossing the street.

Comment Re:The pitch for his product is wrong. (Score 1) 166

Indeed.

If the merchants were on the ball they would have real people wandering around their stores helping customers. Then they wouldn't need technology to bombard us with ads. If a sales person points out a special to me, or brings another product to my attention, I won't mind.

I did a lot of work a few years ago with assisted GPS, that used both GPS and the cellphone network to determine location. I did one test where I was driving around a parkade in downtown Seattle. The assisted cellphone fixes were spot on. The GPS fixes were - literally - all over the map. The I drove along the nastiest urban canyon I could find (under the monorail), and out the I-90 bridge/tunnel, with all the big underpasses and things that confused every other GPS.

Our stuff basically worked, but our marketing person still managed to bankrupt the company. That was another matter. It was fun while it lasted.
