There are a few "progressive" contact lenses as well. I use Air-Optix with great success. They are NOT weighted for orientation but (I believe) have a radial variation in power, and somehow your optics processing center learns, very quickly, to use the reduced power info for short-range work and the full-power info for distance viewing.

That said, the day either medication unstiffens my natural lens or a focussable artificial implant is approved, I'm going to jump at the chance. In fact, I'd prefer the latter so I can dump my -8 diopter contacts!

Dunno why it's necessary to remind you of this: https://what-if.xkcd.com/5/ .

If AI gets "out of hand," just pull the frakking plug. Stop thinking it'll have some magic way of staying powered. This is why sieges worked in the medaevil days: sooner or later the castle runs out of food, or water, or batteries for their cellphones.

Sounds like an ideal site for all-optical computing.

No, I'm not serious -- there's no chance of designing a completely electron-free system of a computer, memory, keyboard, and display. (at least not yet...)

But really -- it's not hard to build Farday-cage-style workrooms. It's things like RF LED light controllers, RFID door / ID badge systems, and all the other little things (OnStar) that nobody thinks about.

There are some quality/safety standards for UK automotive software

Those are just voluntary guidelines that everyone is free to ignore.

Oh, please. Do I have to quote you the formula for determining whether to make something safer? It involves cost of new parts, frequency of accidents, cost of lawsuits, and possibly soap made from human fat.

Comment The next USA nuclear power plant accident is: (Score 2) 128 128

Sorry for the flamebait, but the next "accident" really is the complete failure to start building more power plants. The cost we're incurring by sticking w/ fossil fuels, in environmental damage, human health, $$ flowing to the Middle East, far outweighs either the cost of nuc plants or the potential hazards of such plants.

Not all disasters are active. Some are purely passive but just as destructive.

Hah. Just wait 'til someone tells them those radio sources are in the day sky but invisible . You know, invisible just like radiation!

So... if sunlight's bad for vampires, but the moon isn't, even tho' the moon is lit primarily w/ sunlight, does this mean vampires could live happily in houses where all sunliight is reflected once before entering the house?

Lim as x->0 of X/X =??

Sorry,can't tell if you're asking a question or posing a rhetorical response.

The answer is "1" . The limit is NOT the same as the value of the expression at 0. Calculus is loaded with examples of functions whose limit is not the same as the value at the stated point.
