It probably makes some sense for vehicles that are only used in big cities, since it moves the pollution.

London has had a few hydrogen buses for a few years now, but I don't think there are plans to develop them beyond a trial fleet.

An electric bus (all batteries) Also exists, but isn't yet practical.

And the price needs reduced? Wha?

Using your example:
1. "Aerosmith, standing ticket, $400"

2. "Aerosmith, with backstage pass*, $xxx" (*backstage only for first 10 people to arrive)

3. "Aerosmith, with backstage pass, $600"

The second ticket could be considered misleading, even with the small print, and especially if the price is close to $600 rather than $400.

(IANAL, this is vaguely remembered from a basic law course at university several years ago.)

Why not? Why should the creator not be able to impose any restrictions they damn please? As long as they aren't in a position to prevent you from rejecting their entire creation, they ought to be able to attach whatever strings they want.

Many countries have laws preventing unreasonable contracts, and judges that will often side with the consumer when a contract is intentionally misleading etc. These terms would need to be made very clear, and the price reduced too.

High pressure air then

FT2ndArticle: "We have a fleet of rail-head treatment trains which clean the rails using water jets and then apply a sand-based gel to help trains gain adhesion."

Another page says there are 55 treatment trains. There are something like 4000 "trains", so maybe the point of this system is it can be attached to normal trains, rather than requiring a special train.

Comment Re:Better than the USA (Score 1) 70

While you can argue that out in the boondocks high speed internet is harder to do, what is happening in markets like NYC makes the US look like a joke in comparison with other countries with cities of a similar density.

The population density of the Outer Hebrides is 9/km^2, about the same as the Scottish Highlands. The Inner Hebrides have 4-5/km^2. I'm pretty sure that will be the least densely populated place in the whole UK.

(However, I live in an out-of-the-way bit of London, and get about 2Mbit/s. That's very unusual though, so unusual that I didn't think to check before renting there.)

Motorways aren't E roads, they are M roads. Scotland and Ireland don't have any E numbered roads.

Ireland and Scotland have E-numbered roads, but in Scotland there aren't road signs with the numbers on (the UK doesn't sign E roads).

Comment Re:With lots of dark meat? (Score 1) 189

Last time I bought chicken, I specifically bought whole legs, no breast meat.

That phrasing sounds like you rarely buy chicken. Is that normal in the US? I'm surprised the sibling post says you'd need an "odd market in a poorer part of town".

In the UK, 800 million chickens are slaughtered each year, about 14 each, but lots are also imported. British people eat more chicken than anything else.

A 1.6kg chicken is £5 ($8), which is really cheap compared to buying cut-up chicken. It's not too difficult to cut off the majority of the meat to cook as you wish. Make a soup from the carcass by dumping it in a large pan with water, some roughly chopped veg (onion, garlic, carrot, potato) and seasoning, then leaving it to simmer for an hour. Most of the meat falls off the bones.

Alternatively, roast the whole bird, eat what you like, save any big bits for sandwiches/etc, then make soup from the leftovers the next day.

Let's see.. things that won't be digitized anytime soon:

Thumbprint, perhaps?

Since September you can pay for transport in London with a contactless credit or debit card. (There's no need to pre-register or anything, but foreigners should check their bank won't charge an unreasonable fee on a £1.45 transaction). They claimed to be first to set this up, including some new special kinds of keep-people-moving-and-deal-with-the-fraud-later transaction, so I expect it will catch on elsewhere in the next year or two.

"Favorite"?

Data structures are tools. I don't really have affection for any particular one. It depends on what I need them for.

And does the job require implementing one (assuming you are using that word the way I think that you are)? Or does it involve using them, in service of business goals?

It's an interview, so I'd take "favourite" to mean "interesting".

And if someone can tell me how to implement a linked list that's a good start. Even better if they can use that to tell me when using a linked list is worse than using an array list, and vice-versa.

Comparing the U.S. the little toy countries in Europe is silly. They are about the size of one of our states. It is much easier given their pop. density to keep their little toy grids up and running.

The European countries have connections between them -- mine (UK) imports/exports power from Ireland, France and the Netherlands. There are plans to connect to Norway and Iceland (not in the EU).

http://rrc-energy.com/electric... shows most other countries have many more connections (since they're not going across water).

Comment Re:8X cost increase up front (Score 1) 516

Something like a railway cable trough, typically concrete, is common in Britain at the side of most railway track.

But it's a criminal offence to trespass on the railway.

Better example: buried cables along canals in London. Only pedestrians and cyclists (and horses) can use that path, could it stand up to cars and lorries?

(I'm pretty sure the electricity company will use boats and barges to maintain the cables, which is probably a lot easier than having to divert road traffic etc, and earns them eco-points.)
