Comment Remember the Morrisons in _Scientific American_? (Score 1) 68

Decades ago, before SA became dumbed down, Philip and Phylis Morrison reviewed books for them. They'd (IIRC) do three or four each month, and with one exception they never got below a very good rating. I always assumed that was because there were way too many good books to make it worth while wasting ink on mediocre or bad ones. The reviews themselves were usually worth reading for their own sake—I learned a lot from them.

I guarantee you they were in no sense cheerleaders or shills. They just knew how to make good use of their time.

The one book with a bad review? The Bell Curve , a pseudo-scientific screed trying to justify racism. The Morrisons devoted that month to the single review, showing why it was such a disaster. (For detailed coverage of what's wrong with it, see Steven Jay Gould's The Mismeasure of Man .)

Comment Described attack isn't done for money (Score 1) 1

Future Shop spokesman Elliott Chun told CTV that individuals bought the iPads with cash, replaced them with the model clay, then returned the packages to the stores. The returned fakes were restocked on the shelve and sold to new, unwitting customers.
[...]
"It really saddens Future Shop that people stoop to be this opportunistic and make money in this kind of organized way."

Kinda tough to make money by buying the product first, then substituting the clay. If it's done that way, it must be a prank. This doesn't add up. Who spends $7k (ten bricks) for a prank.

The only way this makes money is if the substitution is made before the box hits the checkout. Methinks me smells a rat.

Comment Siri's networked? Spooky. (Score 1) 2

. I don't have an Iphone, so I only know what I've read online, but Siri's needing the network to be up creeps me out. This means in some sense Apple has access to your queries, and could do anything they want with the information. And how long before the gummint notices this and starts generating search warrants for it? Or just asks, and Apple instantly folds and turns it over?

. This is why I like my phones dumb.

Comment Hooking solar to the grid: maybe a problem (Score 1) 439

We installed solar panels a couple of years ago, and they've been a Good Deal. (Like, zero electricity bills four months a year. In New England. :-) But my jaw dropped when they explained that they won't work during power outages(!).

The base problem is you have to avoid putting juice on the grid when a lineman's up there thinking everything's dead. Not good. There are ways to avoid this (ask anyone who has a gasoline generator hooked to their breaker box), but presumably the vendors want to keep the cost down so far as is possible.

So there are two aspects that may come to bear. First, the inverter (takes DC from solar panels and converts it to AC for the grid) is rigged to shut down immediately if there's no grid power (and wait five minutes after it comes back to resume operations). Second, it must synchronize its AC waveform to accurately match what's coming in. (Things get wasteful if it's a little out of phase, and dangerous if it's a lot out.)

So what I'm going to ask the inverter manufacturer come Monday is whether the incoming waveform is used to decide whether we've got kosher grid power. If so, will these experiments cause the frequency to depart from 60.00 Hz enough to cause the inverter to turn itself off? If so, there'll be a lot of people with solar panels who'll be very upset with these changes.
