We have used nuclear reactors on probes (e.g. all 5 interstellar probes), as well as tested ion drives which could be run from a nuclear reactor.

AFAIK, of all nuclear technologies, only nuclear pulse drive (repeated atomic explosions) could actually lift a rocket off of earth. There are reasons we don't use that one, we have quite enough nuclear fallout on our planet already. I doubt even the Chinese would launch one.

Transistors are analogue components.

I have seen a USB plug in an Ethernet socket. It fits perfectly, and if you get it in right it even locks in place!

We use miles and miles per hour, and miles per gallon. But fuel is sold in litres, not gallons. And it's a different-sized gallon to the US gallon, which just complicates car efficiency talk.

These days miles per £GBP is far more important though, with fuel so expensive and electric cars coming in.

48" is approx 120 cm, so you'd put a screw in every 40 cm.

Note that in a metric country the sheet is likely to be a round metric number, so 120 cm is much more likely than the pain-to-divide 121.92 cm that 48" actually is.

How about if your section is a foot and a couple of inches larger than a yard, and you need to divide that into 3?

Only as much as the book is a crime against the radio show. Douglas Adams wrote them all, after all.

The only crime would be a "book of the film".

I love searching for "XYZ review" and getting "be the first to review XYZ!" on a billion shopping sites.

It doesn't say they're bringing the steam store to PS3.

The features it lists are:
You can bind a PSN account to a steam account.
Trophies earned in Portal 2 on PS3 also unlock the steam achievements. Achievements earned in Windows or OSX do not unlock PSN Trophies.
You buy the PS3 version of Portal 2, you get the PC version free. Via a code in the box.
While playing Portal 2 you can chat to people on steam on either platform.
You can play Portal 2 multiplayer across-platform.
Savegames are automatically copies between PCs and between PS3s using the steam cloud. They are not copied between PC and PS3 though.
You can't play Portal 2 on PS3 and anything else on your PC's steam account at the same time.

Don't put a desk Mic by/over a keyboard, you won't be thanked... otherwise they're fine.

I've had my cordless headphones a few years now, I got them massively discounted in a sale. They still sell for more than I paid! Worth every penny, they've just lasted so much better than any non-cordless I've had before.

No hiss, the only downpoint is that if the source is too quiet (i.e. silent for a few minutes) then the transmitter turns off and the headphones pump loud static into your ears.

They try that anyway. Normally by not finishing on time and threatening to just leave it unfinished if you don't pay them for the extra days.

Why not? Everyone else is.

I don't care much, but cordless headphones are so much nicer than having a cord that gets trapped in chair wheels.

RAID is not backup. A backup lets you roll back to previous versions (preferably from a choice of several). RAID does not.

Actually, holograms do work like he said. You do focus as if the image was really at the depth. This is because a hologram reconstructs the exact light waveform that was recorded.
