Qt Creator is pretty damn good
I've found it much nicer to use than Visual Studio 2010, notably it's much easier to bring up a program written on somebody else's computer and I've found its code modelling to be excellent.
It's free and open source.
The only annoying bit us that code panes are stuck in one window, once that is fixed it will be damn near perfect for C++ dev.
Re: camera on a stick etc.
These "Smart Pens" with "Smart Paper" have been around for so long that they are the common and accepted way of signing off important documents in some areas of industry.
Two years ago (so before this patent was filed) the shipyard I was at used them for signing off things like "yes, the engine in this ship does actually work" - the kind of thing where rectifying a mistake costs millions so you want to be very sure!
(I never signed with the pen, being a pleb for a subcontractor.)
They'd already been using them for a few years before I saw them - not least for "Yes, that's the right size engine for the ship you'll be building in two years time."
Thus the prior art goes back a very long way.
Reading an early draft of EN-ISO 14819-2, I found a few slightly odd ones:
627 - No Motor Vehicles Without Catalytic Converters (Why would that change?)
628/629 - No Motor Vehicles With Even/Odd-Numbered Registration Plates
28 - Road Closed Intermittently (Huh?)
709 - Blasting Work
37 - Restaurant reopened. (What, no pub?)
1479 - Gunfire on Roadway - Danger (You don't say?)
Possibly the strangest would be: 1477 - Police Checkpoint.
Why would they advertise that?
Of course, the actual standard requires monies to be paid, and I'm not bothered enough to find out what exacting changes happened in the end.
Re: Switch it off..
You are aware that modern TVs draw under 0.5W in standby?
Considerably less than a smart meter, and probably less than a dumb one as well.
Standby is irrelevant these days.
The biggest 'hidden' consumer is probably phone chargers. They are built tiny and cheaply so have relatively high quiescent consumption, and are easy to forget about.
Some set-top boxes are pretty terrible though - some of the 'Top-up TV' ones draw a good 20W in standby, becuase they never actually power down.
None of these will be even visible on a smart meter display if course, as they will be hidden by the fridge or freezer, which draws small bursts whenever it warms up inside.
Re: Why this is a stupid idea
The problem you've described is that they cannot see an invisible barrier, which makes perfect sense on account of it being, well, invisible.
Avoiding invisible barriers is clearly not a vision problem, it's a knowledge problem. You have to know that barriers like that could exist, and how to identify them.
Large, vertical sheets of transparent material are a very recent invention - so there aren't any structures in the bee brain that could acknowledge their existence.
There's a video doing the rounds of a dog that won't climb through a yet-to-be glazed glass door. The dog knows that things that shape normally have an invisible barrier, so assumes it cannot pass and waits for the door to be opened.
Re: rate of change
Rate-of-change is far more accurate than absolute if you are using accelerometers.
Unfortunately MEMs accelerometers (basically the only kind you can afford) are incredibly noisy.
This does mean that an accelerometer may be too noisy to monitor a balloon launch, as the linear accelerations are very low post launch. It may be worth looking at this though.
- A lot of people consider trying to use MEMs accelerometers to determine altitude of a platform but double-integrating tends to amplify the noise beyond any sense of usefulness.
Aneroid capsule sounds a very good idea to me.
These are also easily available from old-school barometers, although I'd want to test one in a chamber to be sure it can survive to altitude as those might not be intended for such low pressures!
Re: Balloon radius
Interesting concept, the balloon should be fairly easy to identify, as it's a very different colour to the general sky.
However, vision is very bad at detecting size - even human vision is terrible at it - it's much better at determining shape and attitude.
Casualities arising from renewable power are quite high
Just for wind power in the UK alone, the HSE said its figures showed three fatal accidents between 2007/08 and 2009/10 and a total of 53 major or dangerous incidents in the same time frame.
Wind turbines are inherently dangerous to work on or near - it's a lot of exposed work-at-height, in windy conditions.
There are over 100 deaths known to have been directly caused by wind turbines (most in the USA)
On top of that, they render large areas of the countryside or seabed uninhabitable and unusable because they often throw large pieces of ice long distances, and occasionally throw large bits of themselves as well.
Thus you cannot live or work near them, and to generate any sensible amount of electricity you need a lot of them over extremely large areas.
Sorry, but by doing any research you'd find that wind turbines are not safe.
Re: If these wavelengths can hardly penetrate anything...
You mean like your TV remote?
Fast switching of LEDs is how TOSLINK optical and TV remotes work. The bandwidth is very low as it can only use brightness for data transfer, because the LEDs emit relatively wide band, unpolarised random phase radiation.
That also makes them extremely reliable in terrible conditions.
In proper fibre optics the bandwidth is much higher because the laser diodes are extremely narrow band and in phase - if not polarised as well. So much more possibility for data transfer.
Which of course means they need very tightly controlled conditions - the inside of a glass fibre.
Re: Larry Kim is wrong.
However, if you annoy visitors enough one of two things happens:
1) They go away and never come back.
2) They install an ad blocker and never see another web advert.
Both of these are failures for the advertiser, and the latter is more serious.
Option 2 is more likely on a site that the user finds compelling because they want it despite the annoyance, and becomes almost certain if it has a social element that allows users to talk to each other.
Somebody will discover ad blockers, and then everyone will get one.
Re: not really the same thing
They've got to get the GPU firmware into it somehow, I thought that was a pretty elegant solution that allows later updates to GPU firmware quite nicely.
- and keeps the price down as no need for any extra onboard Flash or seperate BIOS/bootloader silicon.
Re: Software tweaks?
They have had quite a long time to be doing and testing those tweaks, IIRC it was the final approach and dock.
Given that docking takes a few minutes, they can do a hell of a lot of cycles of hardware-in-the-loop tests, and even more sim-only tests in the time they've had.
My guess is they've been testing what to do if it's gone to hell in as many different ways as NASA can think of.
Re: Something missing from this analysis, surely?
The CAP is a truly insane little treaty, with a great many examples of this kind of stupid waste.
It really does need to be completely abandoned, as although there probably are some good parts, they're lost in the mire.
It's what happens when you put a load of politicians together and tell them to solve the problem of food production - they invent a bureaucracy and give it the most complex rules they can come up with, forcing farmers to game the system in order to make a living.
Then as soon as they do that, the rules are changed to stop that particular way of gaming it, some farmers go bust and the rest have to find another way.

@ShelLuser - Not sure what you're trying to say there.
At the time of posting, a Blackberry sits at number 8 and the LG Xpression feature phone at number 16, followed by Nokia Lumia 900 at 17 and 18.
Everything else in the top 20 is an Android - most are Samsung, and there's a couple of Motorolas and HTCs.
The real question is whether they're actually making any money.
Re: The drive needs to be re-formatted?
It's usually EXT2 or EXT3 as almost all STBs and Smart TVs run on some form of Linux.
FAT32 doesn't allow big enough file sizes for most HD recordings and quite a few SD recordings.
- Though on a Sony TV it's probably something completely proprietary that is impossible to mount on anything else (including other Sony TVs) by design intent. Or have they learned that lesson yet?
Re: his engineers have found batteries that could power a flight for 100km (62 miles).

Re: An operating system is what it's creators want it to be
It's not a God-given right, it's a law-given right.
Monopolies are universally known to be bad for the consumer in the medium to long run, for exactly the same reasons that they are good for the monopoly holder.
Namely that you can sell rubbish at very high margin, refuse to improve the product and still the consumer is forced to buy it.
Thus there are laws to limit monopoly powers.
You may disagree with the extent of these laws, but they do exist and must be followed. At least until the lobbying arm gets them changed, anyway.
Microsoft are hoping that Apple and Android save them from charges of abuse of monopoly, whether that will work is yet to be seen, but the more they lock it down the more likely that is to get tested in court.
WinRT (WoA) does not have a classic desktop, it's Metro only, and locked to the hardware that uses technical measures to ensure you cannot run anything else.
Thus if it actually takes off, we're back where IE6 came from - unpublished APIs that only MS code can access, preventing 3rd parties from making competing apps.
That can only be bad.
It would, except that almost everywhere now has or still needs wideband antenna and amps.
Originally because of Channel 5, later due to the various Freeview shuffling stages as even if the final result was a given band, the muxes went through others to get there.
Most of greater london has no need of amps anyway, it's once again people in the countryside (notably Scotland and Wales) that will get hit the worst.
That last part implies a computer driver would be safer, because it would not drive off the cliff.
It might still hit the deer, but it should be better at braking and steering accurately than an average driver so is more likely to avoid an obstacle as long as it can detect it.
Probably not Stig quality, but most drivers are not that good.
Re: 18 lifeboats for 1000 techho-entrepreneurs
Modern lifeboats take quite a lot of people.
100-man boats are easily available, so that's a possible 1800 lifeboat capacity - before you even start to consider the liferafts.
Of course, you've forgotten to include the crew. There are probably going to be 1000 crew members to run the vessel - it's not just serviced apartments attached to office premises.
They have to generate their electricity, maintain the propulsion (you can't just anchor that far out), plus all the general maintenance of a steel vessel in an ocean and the sailing.
I think there are two real killers of this project though. Latency and fuel.
Latency of satellite internet links can easily top 500ms. Laser is only viable in good visibility and within sight of shore, so any laser link is going to fail much of the time.
Then there's the fuel - they are going to have to bunker a lot of fuel simply to run the ship.
If you count Windows Mobile, then yes.
A lot of corporate "emailphones" used to be either Blackberry or Windows Mobile - don't have figures for the split, but pretty sure WM was a clear second place due to the Exchange server integration.
WM is now properly dead and being buried (even the app store is closed) so corporates are forced to leave WM, and the WP7 marketing position appears to be "Don't want the corporate market", so WP7 won't even get considered..
My next company phone looks practically certain to be either an iPhone 4S or Samsung Galaxy S II/III.
So the 'droves' is fairly accurate as all the corporate contracts vanish - probably mostly to iPhone
@Manu T - Nokia/Symbian no longer exists.
What you forget is that Nokia's CEO publicly stated that Symbian was rubbish and dead.
This is a terrible shame, because neither of those were actually true when he said it - though the former had been fairly accurate about a year prior.
Now the latter is true, because nobody in their right minds buys an operating system that the manufacturer has publicly declared dead.
Face it, Elop personally killed Symbian. It's all over bar the lawsuits, and unfortunately lawsuits take so long that they can only find blame and never correct stupidity. It's also fairly unlikely that he'll ever be held properly responsible for the destruction of shareholder value he has caused. All we can hope is that he won't be given the opportunity to kill any other companies.
@A J Stiles
Except in the United States of America, where the DMCA specifically makes doing that illegal.
So far that isn't the case in the rest of the world, though several parties are clearly pushing for it.
Re: This still costs real money?
Actually, MPEG-2 is expensive!
H.264 is much cheaper as well as being a better codec.
That said, given that MS are part of the MPEG-LA in the first place, I would have thought their cost was zero (even if it's an out-and-back) while an OEM's cost is high.
I suspect this may actually be an attack on MPEG-LA. I wonder why.
What exactly was wrong with CEEFORM?
Was it simply that it's already a standard for all the voltages and currents used, colour-coded, tested and has pilot pins available to ensure a good connection is made before applying power and to unpower during disconnection?
I see no pilot pins on the plug shown, so this thing is really going to arc.
It looks like it has all the disadvantages of CEEform and none of the advantages.
No covers over the pins on either side, so kids can stick spoons in them.
Send the designers home, they have no clue.
Bring back the people who designed the UK plug.
Re: Being a civil serpent means you can mess with people
The difference is when the customers can leave and cause the place to close.
Your supermarket is slow and awful? Change it.
ISP? Change that one... Oh, some people can't and oddly they are the ones who get the worst service.
It's all about being able to deprive the organisation of revenue, and for that lack of revenue to be able to close the organisation.
When the organisation cannot fail, it will rapidily become terrible.
The civil service is a classic example of a set of organisations that cannot fail no matter what they do. The management are never held personally responsible for anything and that makes it even worse.
Who is going to eat the consequences of this latest failure? An underling, a manager or nobody at all?
Re: Never use credit cards.
In the UK simply using a credit card gives you the protection of the consumer credit act and a big bank that wants to keep its reputation and business.
Reversing a fraudulent credit card transaction is easy, and you won't be out of pocket during the process.
With debit card transactions it takes a while to get the money back, and you may end up overdrawn or worse before discovering the fraud.
Re: "tories still support him"....
Don't think the Tories support him, they just agree with you that they have no clue whatsoever what it takes to run a company so can't make such a pronouncement. Seems that the other parties hold no such compunctions.
They are also right that the committee did not have the scope or power to state that Murdoch is unfit in any meaningful way and so should not have done so - that's the job of OFCOM and/or Companies House (depending on the reason - both are plausible in this case).
However, they could still recommend to Parliament that he be locked up for contempt for a few years.
It concerns me that the only 'punishment' Parliament seem to be considering is simply telling him that he was a very naughty boy and really shouldn't do it again.
That makes Parliament look weaker than the ASA for $deity's sake.
Re: Oh Crap
The fun part is that it doesn't matter.
Nobody will actually use these gTLDs, and the only people who may be affected are browsers who might get asked to alter the heuristics for the autocomplete.
If they don't bother, no end user will give a damn if they never see a .marketing domain.
The weird part is really that marketers think they are valuable. The most valuable part of a URL is clearly the first few characters, becuase that is what a user types first. If your site comes up top of autocomplete...
Re: re. Performance
The data requirements for this are minute -153 x 3 bytes per frame, 459 bytes. 24fps is plenty, so the necessary data rate is less then 90kbps.
This prank is almost trivially easy to design and can be built quite cheaply.
It'll cost you a £40 LED parcan or LED strip with driver per window, and for a building this size with openable windows, a drum of Cat5 cable and a £10 USB DMX adapter. (This is less than one DMX universe.)
Then you just need a suitable version of the game application, and the basic Tetris is pretty trivial.
The reason it's not done more often is politics - it's hard to get permission to do this kind of thing to office buildings that are big enough for it to be any fun, and unlike projection, you can't tear down fast enough to escape if you try it without permission.
>> Nokia destroyed themselves by focusing on Symbian.
> No. Nokia destroyed themselves by focusing on Windows.
No, Nokia killed themselves by changing their minds every few months.
Symbian is the future, develop this, no that, no the other way!
Meamo/Meego is the future, develop with Qt!
Symbian and Meamo/Meego are the future, develop both with Qt! (sigh of relief)
Actually, no, **** you all. Windows Phone is the future, develop with Silverlight.
Now bend over again, the next version of Windows Phone will need WinRT! (If you're lucky it'll still run your Silverlight but you won't have access to anything new.)
Telling their third party developers to throw away their codebases every few months is what killed Nokia, and part of the reason Windows Phone is flatlined.
No third party developers want to waste paid man hours on Windows Phone. Tiny userbase and they already know that it's all getting thrown away - so the only things worth doing are "coffeeshop fart apps", and things Microsoft or Nokia have paid you directly to write.
Re: Since when were sentences supposed to be a deterrent?
Killing someone doesn't really manage much in the way of rehabilitation, so it can only be a deterrent or revenge.
Re: Mind numbingly simple
Ninjas, that's not a valid comparison.
The contractual relationship between you and HMRC is essentially you paying the Government to supply you with the various useful stuff of a nation - education, healthcare, law and order, defence etc.
If you don't want to accept that contract then you do technically have the option to leave the country and move somewhere where some or all of the above is not provided and therefore doesn't need paying for.
You probably don't want to do that though.
Most states do sanction killing in self-defence, however I fail to see how killing someone who's already locked up can ever be considered that.
Re: Go arounds
I offer the evidence that "The Day Britain Stopped" is a drama based on the premise of a disaster occuring, and therefore contains a similar amount of truth as "The Day After Tomorrow" and "The Day Of the Triffids".
If they did their research and found that the disaster they based the programme or film on was either impossible or extremely improbable, they'd have no entertainment. Thus either no research is done, or the research is ignored when inconvenient.
In this case I'd guess the former, given the statement from NATS.
"This programme presents itself as dramatised documentary. However, it is not only based on a highly unlikely scenario, but deliberately ignores - or misrepresents - almost every standard safety system or procedure currently in use."
iPod chargers were weird.
They used to actually communicate with the charger to determine the charge rate, presumably so Apple could charge more for their chargers.
They now follow the standard - shorted data pins means no data, so eat as much power as you want.
That multi cable looks great - captive adapters are a great idea, usually the tip you need gets lost.
A Tumi is a Peruvian knife used for human sacrifices, so it might put ideas into peoples' heads when stuck in the back of beyond...
Re: Handing the defense a gift
"Tweeting" isn't a domain for nerds, and never has been.

Once again, prejudicial
Even if we accept without proof that the website was actually hacked in the first place - ssomething that legally must be proven at trial first - this specific individual is only a suspect, you legally cannot say that he did it unless he has been found guilty.
Otherwise you are being prejudicial, may be in contempt and may cause a mistrial.
You would expect a police spokesperson to know that.
It is alleged that this guy hacked the site. That is all.
What they mean is that a gas giant-type planet would have been spotted by now on account of it being huge (thus occluding stars) and massive (notably affect the orbits of stuff we know about).
Something small, like Earth/Venus or smaller might not have been.
Re: Can't have it both ways
They are accused of abusing the near-monopoly they have on tablets to gain their current position and profit margin in the eBook market.
It would be fundamentally stupid to wait until a company have actually gained a second monopoly by abusive methods, that's how IE6 happened.
The abusive methods must be challenged in the courts before irreparable damage can be done, swhich means going after them when they start tto use them, not dependent on results.
Re: Workable form of mass electricity storage
No nemo, it hasn't, you can tell because almost nobody is buying it. That's the "workable" part, you see?
"Workable" means that it's feasible, economic to build and run, and consumers will accept it.
Electric cars at the required scale are none of the above.
Secondly, in this context, smart meters are only a method of remote disconnection at times of high demand. This is not a solution in the first place, and of course consumers will never accept it.
"At the end of EastEnders you will suffer a blackout to prevent you from making a cup of tea."
Re: Sounds reasonable.
Which valleys are volunteering for flooding then?
We've already built pretty much all the pumped-storage that people will accept - there are plenty of places where it could be built, but people either live there or it's an area of outstanding natural beauty.
Or there are newts.
This is the thing - hydro-electric is incredibly destructive. It's not green, it's only low-CO2.

Then all traffic is bouncing off your own servers going through two VPN connections, inbound and outbound to Amazon.
If that is the case what exactly is the benefit?
Running a Sharepoint server can't be that much of a load that swapping it for doubled VPN traffic is a significant saving, can it?
Oh dear, you confused theory with hypothesis.
Gravity is only a theory, yet you wouldn't jump out of a high building naked.
In science, a theory is something that fits all known observations better than anything else.
Quantum theory fits our observations of really tiny stuff incredibly well.
Re: Is that even a problem?
For a start, it's cooler.
Secondly, the oscillator technique is psuedo-random - that's a chaotic system, not a random one.
Thermal noise can be affected by external sources as it varies by temperature, so not properly random.
Until now the only really high quality self-contained RNGs are based on radioactive decay events, so produce bits fairly slowly and are hard to buy.
This apparently makes high quality randomness really quickly.
Re: Any more on the delivery mechanism?
My guess would be that it takes a quick look through an infected system and drops itself into a Dropbox folder, getting itself automatically spread to everyone sharing that folder.
Going via email or browser relies on either unpatched holes or user error, while Dropbox will spread it by design.
