Except they're not. They use 20% of the electricity but also give out about 40% as much light. To replace a single incandescent bulb and illuminate a room to the same level you need two or three good-quality CFLs.
I'd also seriously question how much less energy they use in real terms. In our place up north I fitted CFLs throughout, hoping to squeeze a bit more than eight hours from a tank of diesel for the generator. With the incandescents replaced with CFLs, we now see six hours from a tank of diesel. Just to be clear, that's *less* efficient, and using *more* fuel. Nothing else has changed, just the lights.
Are you going to force a user to use KDE so that you can talk them through which icons to click to get the printer working?
Of course not. If you need to talk a user through setting up their printer, they are going to be unable to do it whatever OS they're on. From past experience if a user can't figure out how to get something like that sorted out, their choice of desktop isn't going to make any difference - they need to get a grown-up to do it.
Everything is all over the place. Linux will not gain mainstream acceptance until it is easy to support.
If you're in a situation where you need to support a lot of Linux machines, use the same desktop on all of them. If someone wants to use something else, make it clear that you won't be able to walk them through common fixes. Don't be a dick about it though; if someone wants the login details for the IMAP server, don't say "oh I can't tell you because I can't walk you through how to set up kmail", just tell them the details and if they can't figure out out, tough.

Yet another reason why private healthcare must be stopped. Curing people doesn't come into it - it's about keeping them sick enough to stay profitable.
... when I was 11. It was powered by a big tightly-coiled length of bungee cord that you wound up against a ratched with a handle. When you released the brake, it would shoot forwards for an incredible distance with breathtaking acceleration, all powered by renewable energy, mostly derived from sugary soft drinks and pies.
That didn't work so well, either.
On its best-ever test run it managed a good 30 feet or so before the elastic came off the attachment to the drive axle. Once the elastic was off, it coasted rather better and further than it had ever managed under power.
The energy could come from solar panels on your garage. It compresses the air.
How big is your garage? A 1kW solar panel is about 2.5m by 1.5m, or about the size of two slightly taller than standard doors. My compressor draws 3kW from an ordinary wall socket, so by the time you add in the inefficiency of the inverter you're probably looking at four such panels - an area 5m by 3m - to comfortably run that. I suspect that my compressor, with its 200-litre receiver that it can get up to about 150psi before the motor starts to struggle, would just not be enough to power this car for very long. Oh, and don't forget that you could only run the compressor during the day, when you probably will want to use the car. If you're going to store the power in a bank of batteries, why not put the batteries in the car?
The "air car" websites seem a little light on specifics, but they don't seem to mention how large the receiver is or what kind of pressure it holds. I'm betting it's very non-trivial to fill that, safely, without consuming a lot of power.
It's nasty, and I can see it contributing to component failure in bad cases.
Straight off the obvious cause of failure is by blocking vents and jamming fans. I recently repaired a radio base station that had been used in a smoking environment (tucked away in the corner of a security control room). Despite the ban on smoking in the workplace coming into force several years ago, the sticky residue was still attracting huge amounts of dust, which was causing the radios (in particular the transmitter) to overheat and crash.
its because second-hand smoke is bad for the Apple workers
But there isn't any "second-hand smoke" actually in the computer. There's the residue that you get from smoke, but that's not actually smoke. It's not particularly harmful unless you breath in a big cloud of it, but that's true of any kind of dust. If you're poking about inside dusty equipment, you should be wearing appropriate PPE anyway.
... is not the cameras. In the US, wherever you go there are armed police who are allowed to shoot and kill you, for any reason they feel like. Fix that, then worry about CCTV cameras.
Most Linux desktop environments have this. The default in Gnome is to use to pop up a run dialogue, that will autocomplete recently used apps. I configured the same thing in openbox, with lxpanel.
I haven't seen "V for Vendetta", but I can imagine the sort of thing you mean. The TV equivalent of the raving loony right-wing red-top tabloids, then.
See, that is how you write a helpful answer. Read, and learn.

Most of the obese people I see in my gym spend half their time sitting around, or cycling on the lowest level while reading a magazine.
Most of the skinny people are doing that, too. They'd burn up more energy just walking or cycling to the gym instead of driving over in their car. What a waste of time and money.
If it works well with a potentially poor channel, maybe it would be suitable for improving packet radio systems. Remember that article a week or two back about what would happen if "the Government" shut off the Internet? Go get those amateur radio licences, folks...
A petrol engine has a throttle that restricts the flow of air into the engine, because the air and fuel must be mixed in a precise ratio for the engine to run. A diesel engine doesn't have this - the air intake is wide open all the time. To control the engine power, you only turn up or down the amount of fuel injected. At all times there's an excess of air, unless you're massively overfuelling in which case you get smelly black smoke and poor performance.
My vague memory of the conclusions were that you breath a lot of diesel exhaust without harmful side effects, although the particulates would keep your pulmonary macrophage in business.
Because diesel engines don't have a throttle there's little-to-no significant carbon monoxide in the exhaust, which is the big nasty toxin with petrol engines.
Not that one - it's the 2.2 litre four-cyl petrol - but I did have a 2.5 turbodiesel version of the same car. After a bit of judicious tweaking on the dyno it produced around 470lb/ft torque at 1900rpm and turned in about 45 UK mpg. Not bad for a car that weighs the thick end of two tons...
313 miles on 15 US gallons of fuel? That's pretty thirsty - about 21 US mpg. My 1988 Citroen CX with its heavy carb-fed 2.2 litre engine can easily break 30 US mpg. I was slightly irritated to find that it barely achieved 34mpg on a long run (around 350 miles) at the weekend. Obviously time to get under the bonnet again...

PL-238 antenna connector
That would be PL-259, and you *don't* want that on UHF. They suck above 150MHz. They suck a bit above 50MHz, at that.
Either way, it would be trivial to identify if the bulbs are not consuming their rated wattage by plugging in a kill-a-watt and measuring it.
Wattmeters don't tell the whole story, because CFLs have a frankly atrocious power factor.
CFLs + Efficient, a bit longer lifespan
Except they're not. They use 20% of the electricity but also give out about 40% as much light. To replace a single incandescent bulb and illuminate a room to the same level you need two or three good-quality CFLs.

Okay, but one gallon of fuel weighs closer to five kilograms, than one kilogram.
A petrol engine has a throttle that restricts the flow of air into the engine, because the air and fuel must be mixed in a precise ratio for the engine to run. A diesel engine doesn't have this - the air intake is wide open all the time. To control the engine power, you only turn up or down the amount of fuel injected. At all times there's an excess of air, unless you're massively overfuelling in which case you get smelly black smoke and poor performance.
That works out to 45 gallons/acre which doesn't sound unreasonable to me.
That seems pretty unreasonable to me. You'd be fuelling your tractor every half hour or so, at that.
Even for something with a 400bhp engine, 45 gallons per acre is approaching the fuel efficiency of an engine fire.
My vague memory of the conclusions were that you breath a lot of diesel exhaust without harmful side effects, although the particulates would keep your pulmonary macrophage in business.
Because diesel engines don't have a throttle there's little-to-no significant carbon monoxide in the exhaust, which is the big nasty toxin with petrol engines.
Isn't the Citroen diesel?
