Re: It must be us old fogeys with no perception of speed or distance
Convoy slipstreaming behind an "18-wheeler"?
Clearly only in America... I think that's the only place the big lorries have the same motorway speed limit as the cars. It really won't fly in the UK when you can SARTE and get there an hour later per 200 miles than in "manual".
Yes, it'll save a lot of fuel - but driving at 50 insteads of 70 saves most of that fuel anyway, and nobody does it.
Aside from the technology barriers, are you really going to wait for one of those to come along before starting your journey? Of course not! If you're happy to wait for a scheduled journey, you'll take a real train or a plane and hire a vehicle at the other end.
The technology needed to do this is a useful stepping stone to cars that drive themselves on motorways, but don't kid yourself that consumers will ever do it.
HGVs might, though. Many of them already slipstream anyway, I'd rather a computer was doing it.
The whole concept is a very scary thought for other road users though - getting safely on or off at a junction could be made very difficult by one of those formations.
Re: back to coal
I'm complaining because you've done the maths completely wrong.
TWh is a measure of energy (1 TWh == 3,600,000,000,000,000 joules), GW is a measure of power (1 GW == 1,000,000,000 joules per second).
The time component is important. How much energy has the installed plant actually generated? This is not a multiplier of nameplate rating, even with a capacity fudge factor, as the amount of installed plant has changed a lot during the last decade. It should be pretty easy to measure but the figures are hard to find.
Essentially, the problem is that Wind is getting more dangerous (more turbines in more dangerous locations), while coal, gas and nuclear are getting safer.
Also, 6 wind deaths is the UK alone. It's about 200 worldwide over the same time period - again, compared to 4 nuclear power deaths in the entire world.
I do agree with you that we should be shutting down our coal burning plants. I just think we need to be building nuclear to replace them - and the time to start building those nukes was about five years ago, instead of spunking all that money all over tiny wind and solar PV installs.
Re: back to coal
Where on earth did you get that number?
In the last decade, the reported nuclear-power related deaths in the EU are zero, and roughly 4 worldwide - a steam explosion in 2004 in Japan.
(There was also a fatal accident at the Matapuri research reactor and some errors in medical usage of radiation, but that's not nuclear power.)
During the last decade (to end 2012), Wind power has killed 5 or 6* in the UK alone - and far more in Germany.
So UK-wide for the last ten years, 0 nuclear deaths per GW and 1 wind death per GW expected capacity.
The reason is quite simple - almost all wind turbine work is at a height in areas with high winds and poor weather, and as there are a lot of turbines needed to have a decent output, there will be a lot of such work needed.
One recent study (2011) gave the following worldwide death rates:
Nuclear : 0.04 /TWh
Wind : 0.15 /TWh
By that measure, wind is more than three times as dangerous.
Yes, it's three orders of magnitude less dangerous than worldwide coal - but just because cliff diving is safer than bungee jumping doesn't mean we should all go do that!.
* Depends if you include collisions with offshore turbines. I think you should.
It means "used"
Unnecessary, redundant and/or excessive verbiage is a well-known and necessary requirement of consultancy communications.
It's clear that MS want to kill the "legacy desktop" for several reasons:
Firstly, because they now call it the "legacy desktop".
Secondly, because they castrated it in Win8, removing a lot of the really nice features of the Win7 shell.
Thirdly, because they deliberately made it impossible to stay there without installing a third-party shell. There was clearly no technical reason for this whatsoever, because said 3rd party shells do exist.
This clearly indicates an intention to remove it entirely, and given the features of WinRT, the timescale looks like "the moment Office works in TIFKAM".
Re: How to predict share prices.
Actually, Nokia were already sinking when Elop took over. And yes, looking back it was probably because they were the market leader that they spent so much of their energy infighting instead of producing quality goods.
He merely threw almost everyone overboard, manning the pumps or not, ripped down the sails and then set fire to the powder store.
If he's lucky, the powder is wet. Otherwise...
Re: He's very good...
Steve Knox, I must disagree with you.
English Literature doesn't change all that quickly, so assuming he hasn't forgotten more than 3/4 to 7/8 of what he knew then, he still knows a lot more than me on that subject.
After all, the famous dead authors haven't written anything new lately.
It's not like technology, where last year's cutting edge is now really out of date, or even physics, where the theories of any given decade are likely to be proven as lies-to-children during the next.
Re: back to coal
While nuclear might be more expensive to build than wind for 'nameplate capacity', nuclear produces the actual nameplate capacity at any time we want it to.
Nuclear power is also far safer than wind in terms of deaths per GWh.
Seriously, wind power is very dangerous, accounting for a great many deaths every year - mostly due to falls during build and maintenance.
They don't make headlines because they get lumped in with general construction deaths, and they only claim one or two victims each time.
Re: Burning Gas = Electricity
Wind's not as predictable as you think.
While wind penetration stays low (10% or so), it's fine. Push it much higher and it becomes almost completely unpredictable.
Re: I can see it now...
More seriously, I always considered the text to be simply displaying Terminator's internal monologue.
Much better cinematic method than an audio monologue as it emphasised the difference between a human monologue (traditionally done with a voice-over) and the high-speed robot monologue (multilogue?) of the Terminator.
What I'm not sure about is where the idea of a robot's monologue being shown as text and diagrams came from. It has become very common though!
Is my film critique showing? Damn.
Seems like a waste of palladium to me
Much better uses for it than sat on someone's finger.
Personally, I'd rather be able to breathe the air than look at a shiny thing made artificially dull by spray-on concrete.
I'd be happier if they used man-made Pd though, "forged in a nuclear furnace" seems likely to be a selling point in this market, given the crazy "so hard to manufacture" talk that always comes with designer jewellery.

I'll dive through the WEEE bin on Monday, see if we have any in there and drop you a photo.
Probably because there are far, far more of them, most are run by average consumers and they are left running 24x7.
The majority of the commodity hardware sat on the actual Internet or in the DMZ (as opposed to NATed) is running Linux, simply to get a network stack.
ADSL routers, switches, firewall appliances, Internet-webcams - that kind of thing.
Comparatively, there are very few Windows PCs directly on the Internet anymore - it's only really servers these days, and one would hope the admins of the majority are sane and competent.
In most cases the idiocy is probably the device manufacturer, leaving telnet or SSH turned on with a default password.
Very few home users are going to check the security of the WAN port of their home ADSL router, and they aren't going to try SSH or telnet attacks when fitting a webcam to watch the kids from work, they'll just forward the ports or even put it in a DMZ.
Re: Defeating online attacks is simple...
It's not quite that easy, as the Stuxnet attack on a radiological facility showed.
If you can infect the computer that programs the facility, you can use that to corrupt the PLCs that actually run the place later on.
Effectively a kind of sneakernet.

Was playing Mass Effect 2 recently and was struck how "forced" all the facial expressions looked. Very disappointing, given the fully pre-programmed nature meant they really could have done better than "smile/neutral/grimace".

Where in the world is there lots of sunshine?
Hint - it isn't Britain.
It would be genuinely stupid for the UK to invest significantly in direct solar energy, given the general lack of sun.
I leave it as an exercise for the reader to figure out why it's massively subsidised in the UK with huge amounts of money is being thrown at wealthy landowners to install it.
"Leave" doesn't mean the UK
It means the market.
In other words, they'll stop taking the photos and take their image libraries offline.
Essentially, if nobody pays for the pictures they'll have to find a "proper" job instead to pay their bills, and photography will be relegated to a part-time hobby.
No, it's infringement
That's what it says on the actual statute books.
The more you scream about copyright infringement being theft, the less attention anybody will pay you.
FACT is a lie.
Copyright infringement is a crime, but it's not theft - it's more closely related to fraud and breach of contract.
Actually, you can't.
Remote-controlled model aircraft are not permitted to go that high, and the batteries in a quad/octo don't last that long either - 20min is about the longest you'll get.
You can take a lot of really nice photos with a big quad or octo, but the aircraft to carry a decent camera is going to cost £5k or more.
Model aircraft are great for chase cams though!
Small Claims, it's easy
It can also be done online, you usually don't need to go to court in person.
Costs £20 IIRC, added to the claim.
You will have to show that you've taken "reasonable" steps to settle the matter before going to court.
You'd be wrong though.
It's all about the fade, and a ten-step 1 second fade is very visible.
You need at least 20Hz update rate for fades in small tungsten lamps, for LED you'd want 30-40Hz.
10Hz only works for large tungsten, or if the response is artificially slowed to allow internal smoothing to work.
Only "sort-of" dimmable
Better than any of the other 2-wire "dimmable" LED lamps I know of though, most of which only go down to 20%
I would still like the last 11% though.
Re: Sunshine vs Solaris
Sunshine also has the most unbelievably stupid spacecraft crew ever to screw up on screen.
I still chike that they really expected us to swallow the idea of flooding a compartment with oxygen to blow out a fire, when they could just vent it to space...
You know, try a technique that might actually work instead of one that would definitely kill everyone on board and probably destroy the craft as well.
The worst part is that the writers could have got exactly the same "oh hell" result of the aftermath by using an actual firefighting technique, instead of something that made no sense whatsoever and must have sent the scientific advisors screaming for the hills and demanding to be removed from the credits...
Re: I'm not a fan of the surface devices
Nope, this isn't "simply upgrading".
To do a comparison with another well-known portable computing supplier, he's doing the equivalent of getting rid of an iPad and buying a (tablet shaped) Macbook Pro. That's not an upgrade, it's a different class of device.
Windows RT isn't Windows 8. Superficially, they look very similar - but when it comes to what you can actually do with them, they are completely different.
To me this tweet really says "Microsoft exec confused by the difference between a Surface RT and a Surface Pro" as he's bought the wrong one.
Linux is however guaranteed to be available
No matter which Linux you pick, in ten years time you will definitely still be able to legally deploy that specific version.
That's the issue - right now companies are only just starting to use Win7 embedded in released products.
It takes a year or two to build and test the new system on a new underlying OS, so if you lose the ability to licence it only five years after it first became available, you might only get three years of shipping units before you have to switch to a new underlying OS.
Which takes you two years, so you end up continually re-writing just the OS layers,with only one year in the middle for actual new features etc.
Not sustainable, thus a short lifetime of Embedded licensing is a sure-fire way to kill all sales of it, forever.
As other posters have pointed out, several Embedded systems are already on Linux - and with modern toolkits like Qt, transitioning between WinXP and Linux is much easier than it used to be. It's not "tick the box", and probably won't ever be - but much easier than before.
It's also rather nice how easy a Linux is to lock down - after all, an always full screen application doesn't actually need a window manager...
Linux actually has the low-power embedded market almost completely sewn up - check what your smart TV or STB (router etc) runs!
Re: "Everyone that is apart from the people that choose to learn how to use it"
One question to think about:
How many applications do you have installed?
Under all previous versions of Windows, the "launcher" had folders to let you organise your installed programs into groupings, and to let the installer put their links together.
That's gone in Windows 8.
If you have more programs than fits a screen, you have to flick through several pages.
If the installer used to put its links into a given folder (eg all from the same supplier), it won't anymore, you'll have to drag them around yourself.
Even iOS has folders on its "launcher" - and most people have far fewer things installed on their phone than on their PC.
The Win8 Start Screen just doesn't scale. If you've only got one screenful of applications, it's ok. As you add applications, it becomes more and more unwieldy.
Personally, I have well over a hundred applications installed - most are "rarely used", but I still need them and I still want them grouped nicely so I can find them quickly.
- As I use them rarely, I may not remember enough about the name to use Start->type, or even recognise the icon, but finding "widget drawing" in the "drawing" folder is easy.
Doing the same in Win8 Start Screen isn't possible. I must recognise the icon or know its name, or it is almost impossible to find.
- One example of a useful UI improvement that was clearly based on proper research is "Pinning" in Win7 - those few applications I use every day end up pinned, while the more rarely-used stay in folders in the Start menu.
Re: I like it.
There are some things in desktop Win 8 that are quite nice, including the new task manager.
Yes, there are a lot of nice things. It boots faster, has many improvements "under the bonnet" and has quite a few useful tweaks to built-in utilities.
Then they ruined it by ripping out some useful features and cramming a tablet UI on the front.
It's like bringing out a new, faster Ferrari but insisting you cannot buy it in red, and steering now uses a lever.
Obviously you could take it to a paint shop and bolt on a steering wheel, but why should you need to?
Re: This continues to amuse
How can that be abuse of a monopoly?
The only reason Win8's TIFKAM even exists is because they are a monopoly - consumers are essentially forced to buy it if they want a PC at all. (As the OEMs are pushed away from Win7)
If they had a choice, almost nobody would buy Windows 8 - you can see approximately how many would choose it by looking at sales of Surface and Surface Pro.
I'm still pissed off that they neutered the task bar - so much of the cool stuff it did has gone :(
Not "uninhabitable", merely "uninhabited"
As a few earlier posts have pointed out, most of the evacuated area is less radioactive than Cornwall.
Unfortunately there is an outright panic attack whenever radioactivity is mentioned, regardless of the actual level.
Going through US airport security (excluding the flight) probably used to give you a bigger dose due to the X-ray backscatter machine than a day's visit to the "Area 2"
- Hard to be sure as the data on those was never published and probably wasn't ever measured for the staff and the queue.
Re: Unsecured WiFi
Nope, you want to know the ground-level information, not a few hundred metres up.
I really hope they did include measuring the radiation - in fact, it would also be very interesting to do that everywhere.
I'd love it if radiation levels around the world became well-known, in the medium term it would remove the hysteria and replace it with the simple respect radiation deserves.
We'd all be safer for that.
Re: Epic double standards
Yes, but you see, the ASA's dictionary has a few missing pages and they can't afford a new one.
Perhaps we could help them out?
Odd - only suspending those?
In earlier Embedded it was normal to kill the shell entirely and replace it with your own, so merely suspending bits of the Win8 shell seems an odd way of describing it.
In almost every use of Win Embedded, the whole point is to kill every aspect of a "normal" Windows UI and replace it with the specialised UI for the particular use.
- If you can still see that it's Windows after the boot screen, you probably didn't do it right.
That said, manufacturers are only now moving to Win 7 Embedded, so usage of Win 8 is a few years away.
Unless they pull the rug out from under us by stopping licensing of new Win7 Embedded machines, in which case it'll scare everybody onto Linux.
Re: thats nice but..
"Hey, let's spend billions buying underpants!"
"Why? Will it help?"
"Just buy billions of underpants and then get back to me."
Consider the following: P = I * I * R and P = I * V
Power lost = Current * Current * Resistance
Power supplied = Current * Voltage
If you don't understand why these two equations mean higher voltages are needed, you won't understand why the rest of that post wouldn't work either.
Go do some research - it's very interesting.
However, if you don't want to learn any physics or engineering, don't proffer opinions on them because you'll just look foolish.
Re: About Investing, not Investors
It's telling that you only feel able to post your ill-informed bigotry completely anonymously.
It would appear you don't even believe your post enough to associate your long-term (semi-anon) handle with it, which doesn't sound like someone with a genuine religious conviction.
You don't believe, you just hate those different to you, and last time I checked, Jesus didn't say to hate your neighbours.
By your definitions, childless couples and disabled husbands are just as bad as gay marriage, as neither provide the benefits you claim marriage is for.
Do you agree with that statement? Would you deny a paraplegic fiancé the right to marry?
Marriage is a public declaration that two people love each other, intend to devote the rest of their lives to each other and remain faithful to each other, regardless of changing circumstances.
That is valid for any two people.
Re: Why not just build a solar panel that covers half the world....
You earn money on solar by stealing it from the poor.
You get between four and five times the going rate for your electricity generation, and the Grid is forced to buy whatever you generate, regardless of whether the Grid actually needs it or not, or even whether it gets any of it in the first place.
- Yes, this is the same as Tesco paying you £5 for each cucumber you grow and eat yourself.
It's almost certainly the most regressive taxation to ever come out of the UK's central Government - it drives the poor into fuel poverty while handing money to rich landowners.
Yet it was a Labour idea. So much for their "core values".
AC@12:41: You could read the next paragraph: "[America] is the only place I've seen "swipe'n'nothing" credit card payment, anyway."
Also, this statement is just plain wrong:
Contactless payments are authorised, the card provides the authorisationThat's not authorisation, because it's taking money without asking the account holder anything.
The account holder is the only entity who can authorise money going out of an account. If the account holder didn't authorise a transaction, that transaction is unauthorised by definition.
By (EU) law, you must be refunded if the bank permitted a transaction without that authorisation.
So you're genuinely happy that anybody at all can make multiple transactions, each up to %VALUE% (£50?) once they've nicked your card? (Or even without stealing it, instead remotely using the RFID to determine the card number and doing a few CNP transactions until the anti-fraud trips in and blocks it.)
Leaving you with the fun and games of getting the money back, perhaps bank charges (and even court summons) due to going overdrawn or having cheques, direct debits or standing orders etc refused?
For most people it wouldn't take many £50 transactions to do that - just one may be enough.
That sounds like a dangerously foolish idea to me.
Isn't that the definition of freelance?
The tax man will be very interested in any companies complaining about this behaviour, because it's a clear indication that the person is really an employee.
- So the employer has to pay NI, holiday pay, pension etc.
Not sure about other countries, but in the UK, if you can't subcontract your contract then you're usually considered an employee, and not a self-employed (freelance) contractor.
Re: Read the paper...
Isn't that 1-3% based on simple maths?
Area of surface we are likely to build wind turbines on multiplied by watts per square metre an array can generate, compared with giving everybody a reasonable amount of electric?
Sounds reasonable to me, given the paper's content.
Of course, you can argue his area is too small, or that 2/3 of EU energy consumption for everyone is too large, but I rather doubt it's out by an order of magnitude.
So even accepting that, the upper bound on global wind power would only be 10% or so.
The huddled masses of the world's really poor aren't going to stay huddled forever - and the sooner they get to the "modern" living standards the better for everyone, because that's the only way the human birth rate will reduce to a steady state. You'd better hope that happens before peak energy and peak food, because human wave attacks are very messy.
You must be American to like the idea of being able to pay for smallish transactions direct from an account with no authorisation or security process at all.
That's the only place I've seen "swipe'n'nothing" credit card payment, anyway.
The card is not the account holder!
I used to think the SciFi stories were silly where people had credit chips that almost anybody (usually the villain or hero) could easily use to take money from random civilians, but now it looks like the banks really do intend to go there.
Re: This should not be a surprise.
Just because leaping off a cliff is madness, doesn't make climbing the cliff sane.
Burning oil is foolish - if nothing else, it's far more useful as a raw material than a fuel.
However, building wind turbines is also foolish.
Re: One problem with the article...
Maybe you've not heard the term before.
"Dogfooding" means "using your own products internally".
It is almost universally a good thing, as it saves the supplier money and helps find subtle bugs.
Aside from that, would you trust a supplier who doesn't trust their own products enough to rely on them for their own business?
It comes from "Eat your own dogfood".
Re: What about wxWidgets and QT?
wxWidgets is a widget toolkit - it's only the GUI.
Qt on the other hand is a complete cross-platform SDK, however its previous owners spent years developing it for a particular mobile phone OS, then set themselves on fire, slit their throats and threw Qt away.
So Qt is back to being a desktop SDK, now with a host of new, shiny, but unusable mobile OS extensions.
With is a terrible shame, I call it "being Elopped".
The Android (Necessitas) and iOS ports will fix this, but not yet.
You will not find "connect me to a database" widgets in either, you do have to do some of the work yourself.
Try that on a Windows RT unit
If you are going to compare Apples, at least pick oranges instead of monkeys.
