Learn to spell basic English words please, before you embarrass yourself on the internet by getting it wrong several times in one article.
Soundlink Minis are sometimes available for about £130, which helps a bit. And if you want to use two for stereo you can make up a Y-lead (or maybe even buy one) which will send one channel down each leg. Obviously not wireless any more, but much better for using with TV, as the delay through the Bluetooth connection seriously messes up lip-sync.
@AC Yes but I believe the Superhub actually provides the subscriber's identity and bandwidth throttling so can't possibly be replaced by a generic device. They're not just being bloody minded - in fact they're being rather helpful by allowing you to switch off all non-essential functions and use your own router/firewall/access point - "modem mode".
But then you no longer get the benefit of any other hotspot!
Instead of trying to impress us with your paranoia about security (would Virgin really snoop on data flowing around your LAN?), why didn't you just say what we all know - the Virgin Superhub is a crap wifi router and replacing that functionality with a third party device makes the whole experience far better?
Churches are where all the mobile phone masts are hidden instead, conveniently providing those facilities...
Ol' Grumpy: "In BT's case, they also claim they put a Quality of Service policy on the router so the home network always takes priority over the public one and therefore your service shouldn't be impacted."
"shouldn't" is I guess the operative word. Only if transactions were instant would this be the case. Due to the latency of the link, once a data stream has been established, packets can continue to appear from the remote end for a relatively long time even if the local end tries to put a stop to them, potentially saturating the download path and so interfering with downloads the high priority user wishes to make.
Of course, how much effect this has in practice is open to debate.
Sorry, I'm no fan of American imperialism but I was unaware the US had annexed parts of Chile.

...you could at least correct your naive description of "white space". It isn't simply the frequencies vacated by analogue TV, which would be nothing special. As Mage says, it is the parts of the spectrum in a given area which are apparenty not in use for TV broadcasts, requiring a device to be location-aware in order to know what frequencies and transmission powers to use. Unfortunately Mage then rather clouds the issue by going off on one about how free this spectrum actually is.
Those sound as much like hardware as firmware problems.
You haven't heard the impressive spacial effect created by a bit of signal processing on a dual-speaker handheld device then? No it's not proper stereo, but then neither is what you'd get from "two loudspeakers on opposite sides of the room."
You'd have to block GPS as well, as decent ones fly back to launch point on signal loss.
"If the reporting party withdraws their complaint or you obtain a determination of your legal rights, we would be happy to follow up about possibly restoring the removed material." (My emphasis.)
Why on earth would they not restore the material if the original complaint went away or was proved to be groundless?
Your average race vehicle has 7 cylnders then?
I hoped that, being in Australia, they would be powered from 100% renewable energy sources. I'm guessing that, because they're stuck in cities, they aren't.
Then put a micro SD card in.
Your simplistic theory doesn't take into account the fact that we live in a welfare state. Smash yourself up through not wearing a seatbelt and it costs the rest of us to put you back together again.
Plenty of logic to the 250W rule: if you want more, get a motorbike and a driving licence, number plate, helmet, insurance, MOT etc and keep out of most bus lanes, etc. The more powerful these things are, the more dangerous they are for you and others (not to mention the lower the benefits in terms of keeping you fit and healthy and reducing energy use) and at some point this has to be regulated. Yes, of course the cutoff is is a bit arbitrary but can you suggest a better way of dealing with such situations?
You forgot at least two coaxial wifi (etc) aerial cables which, like the rest, simply pass through the centre of the hollow pivot points. This design has more pivot points between base and screen so I assume that the cables pass through each one, following the straight line drawn between them (almost parallel to the back of the unit), and therefore not needing to change direction significantly. There is more than twice the amount of twisting (360 degrees) but it can be spread over a significant distance. There are also more sets of hinges, so the cables can be distributed better. I'm not sure why you have concerns about dirt and grease - they are insulated cables which will stand up to this.
Ha ha ha ha ha! Maybe I'll stop laughing when I hear this miracle of nano-technology, but I doubt it.
"the Android version gets half the storage [of the Windows version]" so you can't compare prices.
I agree, but I think some of it is the horrendous overbrightness of a lot of blue LEDs. In the old days, LEDs were very inefficient and so much more muted. High-efficiency/brightness ones cost more; it seems nowadays they don't so they put them everywhere.
All LED bulb assemblies, whether mains or 12V, contain a bridge rectifier and a switch-mode power supply (LED driver). So the difference isn't as stark as you might expect, but I agree that it seems it should be easier to make a cheap reliable 12V AC LED driver than a mains one. I have eight 3W MR16 LED fittings (12V) in my hall/stairs which, despite being imported from a Chinese tat bazaar, are still working apparently perfectly after several years.
@AndyS - Marcus Aurelius does have a point. You only have to look at what happened when mains reflector halogen lamps (GU10) came along. They started a whole fashion in excessive lighting. With bulbs and fittings being cheap as chips, you'd get one 100W pendant lamp being replaced with a dozen 50W halogens. LEDs will also be sold for fashion rather than practicality, their size and low heat output allowing a whole new generation of lighting which will be exploited because it looks different, not necessarily because it can be made to consume less power for a given light output.
I agree that the step change in efficiency between halogen and LED is a lot greater than between conventional incandescent and halogen, though.
All other technologies used for street lights either cannot be switched on instantaneously and/or their life is reduced by every switching cycle. So as well as being more efficient in the first place, LED street lights can be on motion sensors, allowing them to remain off most of the night without a safety implication.
True, it's hard for an LED to survive in an oven, but most of the time an incandescent will be as "efficient" as any LED as the heat it generates is offsetting use of the elements!
Typical Luddite comments with a hint of "nanny state". (How DARE you take any control away from ME! It's my party and I can pollute if I want to!)
You could get auto stop start on VW Polos (and probably other things) in the early 1980s, before fuel injection and engine management systems, which at the very minimum increase idle speed if they sense the battery is low. Even then they had thought about engine temperature and so were disabled by a thermostat if the engine was cold. No doubt they checked battery voltage too (dead simple), but the Haynes manual is long gone. If they were reliable enough to be incorportated into a retail product in those days, just think how reliable they will be now.
I am fortunate enough not to have to drive very often, but on a car hired recently (an up-to-date VW Polo coincidentally) found the need to turn the key back to off after a stall and to press the clutch before starting (a hire car thing?) far more disconcerting than the already whisper-quiet engine stopping at the lights and starting again so smoothly and rapidly that there was never a worry that it wouldn't be there. Super in traffic jams - hopefully the vehicle in front would be similarly equipped so as not to be pumping fumes at me in the same way that I wasn't pumping fumes at the vehicle behind.
Sounds like you should apply that to your sub-editing...
You're still missing the point though - concentrating the sun's power on one point to get high temperature heat is not the clever bit. They have indeed been doing this for ages, but they have not been doing it with a photovoltaic panel in the way, because traditional methods of cooling would fry the panel. You are asking your 10 year old the wrong question. Please ask how you get water at 90 degrees while keeping the panel below 100 degrees.
Useless version already available, more like. If that generated usable amounts of heat it would tell you the water inlet/outlet temperatures and flow rate in the specs, but these are glaringly absent.
No, AC, no-one is telling you that some of the best scientists in the world have just figured out some basic physics. What a silly statement.
The breakthrough is in applying it. This project looks like several techniques have been brought together to make a practical solution. As far as heat production is concerned, the clever bit is being able to get electricity and useful heat (i.e. at a reasonable temperature) at the same time. Without the specialised cooling there would be a large temperature difference between the cells and the cooling water, so you either end up with fried cells or tepid (useless) water.
Yes, but they're the same as Oyster ones, and because cash fares are so outrageously expensive, very few people don't have Oyster cards any more.
@Steven Jones: you're missing the point - what is done currently is irrelevant - we are developing higher frame rates (as well as other improvements) to go with higher resolutions for the future. You might as well have been arguing in the 1950s that there was no point in developing colour TV because no commercial or broadcast systems captured in colour.
@leon clarke: a 3.5mm jack plug shorts out every time it is inserted.
@Steven Jones: you're concentrating on large-area flicker whilst completely ignoring motion portrayal. The eye will track moving objects, so if you don't wish an object to go blurred as soon as it (or the camera, eg when panning) starts to move, you need a high enough refresh rate. The higher the resolution of the static image, the more noticeable will be the effect so as resolution increases, frame rate needs to increase to maintain image quality. There is evidence that several hundred frames per second can be needed for ultra-high resolution ("4K"). For further explanation, see, for instance, here.
...and at a year old, the "glue" (some variation on double-sided tape by the looks of it) started to come unstuck at the point of maximum stress - the hinge. Before display, backlight, touch screen or aerials failed, I applied epoxy resin adhesive, clamped it shut to set and so far it's holding, fingers crossed.

It is impossible to underestimate just how upset some of us get about these things.
Oh hang on...
If it's just a quote, it needs a subtitle.
How do you know how much an OEM pays MS per machine it ships? It's a closely-guarded secret, which is why when MS panicked and started foisting Windows XP on netbooks to nip the consumer Linux PC in the bud, you could never get the same spec machine with Linux as with Windows, so it was impossible to work out how much the Windows licence actually cost - positive, zero or negative!
Why is it such a secret? Could it be that if indeed it does turn out to cost the hardware manufacturer peanuts compared with a standalone copy, the OEM bundling would be viewed as an anti-competitive subsidy to hinder the adoption of alternative operating systems and applications which run on them (or MS's applications which don't - for no technical reason)? Perish the thought!
Because it is a secret, the court can only award the known price of the software, which is that of a stand-alone licence. I think we agree that this is likely to be far higher than the price paid by the OEM, so that secrecy backfires in a particularly satisfying manner! If this becomes a trend, MS will soon change the way it does things.
Microsoft was the company that institutionalised this anti-competitive behaviour - nay stranglehold - and has benefited from it since the 1980s, so the fact that you think it's "unfair" to penalise the company for it strikes me as quite bizarre.
@Mad Chaz: yes, but that's not the point: you can install any OS on a PC too. But in both cases, non-free (as in beer) software has been bundled with the hardware, for which you can get no refund. I have explained the difference between the two situations above.
@Curly4: hasn't it dawned on you that the case of Apple is one company's non-free software being bundled with the same company's hardware, whereas in the case of Microsoft it is one company's non-free software being bundled with a myriad of other companies' hardware?

I think it's running slow by about a decade.
