That's what I meant when I said the safety profile is well known. Some people are hypersensitive to light, whether it's their eyes or their skin. They already know it, so this won't sneak up on them. For everyone else, it's not going to hurt them to have a high frequency signal modulated onto their light bulbs.

Upsides: Unlicensed spectrum. Pretty much unenforceable even if it was licensed. Little or no bleeding over from desired coverage areas, at least indoors. Plenty of bandwidth to go around. We know the safety profile of this sort of radiation quite well also.

Downsides: Line-of-sight only, so an AP in every room would pretty much be required (or equivalently, fiber from a central AP to every room). Probably can be degraded by "noisy" light-emitting devices, but spread-spectrum will probably get around that pretty well.

It sounds a little like using fiber optics for the last-mile problem, only in this case it's the last-meter problem and possibly without a fiber.

Oh, incidentally, the thread I posted to may be of considerable interest here.

Ironically, it's the tale of a guy who goes to the completely opposite extreme and then wonders why some people would dare to disagree with him.

Go deep, not wide. Offer Fn layers and dedicated keys, but put those dedicated keys in back, not off to the side. If you do expand to the side, expand left, not right.

You may want a Tipro MID, though those are hard to come by in the U.S.

Cherry MX Black switches (heavy linear), relegendable keys on the top three rows. You can get them in either a matrix layout or a staggered ANSI or ISO layout for the bottom four rows. The top four rows are always a matrix. If you want more keys, they come in various sizes and bolt together.

Be aware of the significant problem that the programming software requires Windows. It does not run on anything else. The PS/2 connected versions not only require Windows, but 32-bit Windows. (The USB versions will accept 64-bit.) While PS/2 to USB (and vice-versa) conversion works, it does not allow programming. They must be programmed on their native interface. However, once programmed, they stay programmed and can be used on any system or any OS, and either interface type.

Another option is the Cherry boards I posted elsewhere, though they don't have nearly as much customization ability as the Tipro.

There are simple, off the shelf answers out there, you just need to look at the point-of-sale market. This means you may end up with an unnecessary credit card reader attached to your keyboard, but otherwise there is no real issue. (Besides, wouldn't being able to swipe a card, even a magstripe, be a nice second factor for login?)

As I posted to Deskthority just yesterday:

If that was the case, putting a blob of material on the power supply chip (and nothing else) wouldn't remedy the problem – but it does (see the last post on this page.)

Filing a false police report is criminal in and of itself, even if it doesn't result in an expensive, resource-wasting, and potentially injurious or deadly response from the police.

Do it once, maybe you get away with it. Keep doing it, and you can [i]expect[/i] to get caught.

I think this is a solid indication that you have gone insane in the membrane.

No matter how good your "live view" screen is, it won't be of resolution comparable to a matte glass screen. This may eventually become indistinguishable. However, there will always be a little bit of latency and flicker, no matter how good it gets. The "latency" of a mirror box is and always has been well below detection thresholds for humans.

The only "mirrorless" I'd be interested in at this pint is more accurately a half-silvered mirror. Some of the light goes to the detector, some of it to the focusing screen, and nothing moves. Unfortunately, you sacrifice half your light sensitivity (one stop) for this.

You need look no further than the discrete GPU market for an example of this. Integrated GPUs have long since eaten up the low end. They're starting to eat the middle of the market too. The consequence is that high-end cards escalate in price, and come out less often because each generation has to be milked longer to get the ROI. Another, more fortunate consequence is that even if you don't want to pay for a high-end GPU, you still get something that doesn't totally suck.

Had them? We still do.

They may be inadequate, but they're certainly not impossible.

I lived in an apartment which had a swamp cooler and no air conditioning. Even in the dry air of suburban Los Angeles, it sucked. It required moving massive amounts of air, which meant constant noise. It meant interior doors – and exterior windows – had to be left open.

I suppose it's better than nothing, but so is a fan and a wet towel.

The problem there would be that the epigenome, developed through one's life, would also get reverted. Your body might not recognize the reboot cells as its own.

I have a mouse (the one currently at my right hand side) that is perfectly useful this way. I middle-click without any issues at all. I have another one -- also made by Logitech -- where the spring force of the click function significantly exceeds that of the scroll wheel's detents. The only way to middle-click reliably without scrolling is to reach forward and press down on the leading edge of the wheel, where it basically can't spin under the pressure. Luckily I only keep that one around as a backup. It also has a tendency to occasionally "spin out" and send the cursor (or viewpoint) flying around randomly for about 300 ms.

You'd be kinda foolish to only add one can at a time though. When you needed the last five, why not put all of it in at once? For that matter, why not have a single five-gallon can? It would certainly simplify refilling.

Of course, you'd still be well within your rights to complain about the misrepresentation of the fuel capacity.
