Well duh. If it didn't have both live and neutral then it wouldn't light up. Maybe you are surprised by the presence of an earth (ground) wire? That is required in the UK for equipment that is metal on the outside, unless it meets stringent insulation regs. You might like to feel this live 230V wire to experience why this is a good idea.
As for the fuse, you are correct that it should have been a 3-amp fuse, not a 13-amp one. If the manufacturers put it there, they need a good slap. But you are wrong to imply that the fuse would fail to prevent the lamp from melting. Typical mains wiring will carry this sort of current for many seconds before melting. The fuse will blow in a fraction of a second if shorted, as I have demonstrated on various occasions.
That may be true in some parts of the UK. There seems to be plenty of compulsory music and freely-provided optional music in the schools here in East Lothian, Scotland.
The correct way to observe the Sun (projecting it) is a good thing to do. Pity we are at the bottom of the sunspot cycle right now: there won't be many spots to see. You should, of course put something nice and flammable in front of the eyepiece to see how fast it bursts into flames. (The 8-inch refractor we had use of when I was a student would light a pencil in under a second, IIRC)
My guess is that michaeas is American, while devonborn and AC are not (and may even be from the UK like me). Here we are taught to do a hill start as AC describes --- you fail your driving test if you can not do this. Americans seem unaware of this procedure, to the extent that many manual transmission cars sold there make it hard to do. (For example, the handbrake may turn off the headlights, so you can't do a hill start at night without sending weird signals to other road users.)
Yeah. What he said. I grew up on DEC/Sun gear, which tended to have Ctrl to the left of A. I find the positioning of it in the bottom left to be hugely infuriating, to the extent that I tend to select the option that maps both positions to be Ctrl and eliminates CAPS LOCK altogether. (In the days when I still wrote FORTRAN 77 I would map some other useless key (Sun keyboards had lots!) to be Caps Lock.)
No lie, that. It becomes obvious if you cycle a lot: pedestrians don't look for you because you don't make the sound of an internal combustion engine. I occasionally wish for a device that would make my 1995 Raleigh sound like a Harley-Davidson.
... when you could LIVE?
bada-bing-TISH! Thank you ladies and gentlemen, I'll be here all week.
Seriously, though, did their advertising people not spot what a silly name Wi-Di is?
Parent is dead right. It infuriates me to see equal time being given (for example) to someone who actually understands the climate system and that clown Lord Monckton. But the BBC feel an obligation to do this. They don't seem to get that yes, you do have to give the Tories and NuLab an equal crack at the whip. But you don't have to do the same for a proper evolutionary biologist and a young-earth creationist.
Nobody thinks that the climate was ever in a steady state, least of all climate scientists. What it has done for the last several million years is oscillate between interglacials (more-or-less like now, perhaps a tiny bit warmer) and glaciated periods ( ice ages: a whole lot colder than now -- by about 5 deg C). The temperature difference between an ice age and an interglacial is big, so it is easy to infer it from the geological record. The CO2 levels over that time have tended to be lower in the glacials and higher in the interglacials. None of this is made up: there are good records in ice cores.
Also rather well understood are the smaller temperature changes over the last 150 years. Only about 1 degree, but we had thermometers for that period.
Much harder to get at are the small changes over the last 1000 - 2000 years --- things like the "medieval warm period" Trying to infer these small changes from the geological/tree-ring record is really hard.
So, the executive answer to your question is that the climate changes by both large and small amounts on both large and small timescales. But the smaller the change and the longer ago it happened, the harder it gets to say anything accurate about it.
Both the Nature article mentioned in the summary and the NS article linked by Idiomatick are clear and sensible articles and well worth a read. I do not, of course, hold out any hope that they will prevent the oil company shills and SUV drivers from baying for blood.
Does this mean that they'll be running Linux on the Slim?
Neither TFA nor the justification document says explicitly whether they are buying slim or original, but I get the impression that they will be using the original (non-slim) PS3s.
but after a week or 2 or so you will need to buy ned ones.;)
I think that you have to live in Scotland[1] to really LoL at that one.

In some parts of the continent ( mostly southern Europe: Italy and Malta for sure but France too) it is common for people to shoot small birds for the sheer fun of shooting them. Anything that flies is shot and they don't care if it is edible, or rare, or a protected species. See here for details.
In the UK, shooting of birds is restricted to (a) Farmers shooting pest species (e.g. crows) and (b) rich people shooting specially-reared game birds (grouse, pheasant etc.) and (c) People with green wellies shooting ducks --- they are usually keen conservationists to ensure that there continue to be ducks to shoot and places to shoot them
This all makes it entirely plausible that typical garden birds in the UK see people as less of a threat than is the case on the continent. Mind you, if that sodding blackbird steals any more of my Victoria Plums I will be very tempted to blow him away.
PC ownership in the Far East is much lower than in our decadent Westron cultures.
Indeed, the Shire, Bree and what is left of Arnor have saturation computer ownership and ubiquitous WiFi. Mordor, OTOH, is stuck on DOS 5.0 and 33k modems since the recent collapse of political power in that region.
Noctilucent clouds occur over a very small altitude range (about 82-84 km) Observations of the same cloud from different locations can be used to find the height by triangulation. ISTR that the 1887 observation did this and that it is therefore a genuine observation of NLC.
The question of whether there were no NLC before this date was a contentious one last time I asked. Some make the argument that NLC are very distinctive and that if they were there we would have records going back to the Viking era, as we do with the Aurora Borealis. Others, however, argue that NLC look sufficiently like other clouds and are sufficiently unremarkable to the casual observer that it is not surprising that there are no descriptions prior to 1887. (Remember that the idea that it is worth naming and describing clouds only really goes back to Luke Howard in the early 1800s.)
But seriously, to what extent is this a gain, given that the energy "produced" must all originate in the petrol tanks of the cars visiting the supermarket. I suppose that it is a double gain for the supermarket in that they get some free electricity and also get to sell a bit more of the petrol that makes it.
Or can it be shown that the power generated would otherwise have all been lost in braking for the speed-bumps in the car park?
In earth science one gets the whole culture clash between the hard-core physics/computer types who like LaTeX and the biologist/ecologist types who like Word. I get a little depressed by the extent to which Word seems to be replacing LaTeX, especially given how much less nice the final result looks. If MS can really improve the typesetting then the "Not a chance" posts above are likely to prove wrong once Word 2010 becomes prevalent.

Those are both wuss units. Real physicists measure speed in metres per second.

Just don't point it at any aircraft. The authorities in various parts of the world are getting fed up with this.

The movie may have sucked, but the line is in the original radio series. Which was excellent.

Only if your £23 notes are sufficiently pornographic. (Bonus points to those who recognise the obscure UK TV reference.)

Perhaps the RCC could sponsor the development of a "moderate" button that doesn't select "Redundant" when I meant "Interesting". Posting to undo same.
