1 Core 2xF MHz or 2 Cores F MHz

Both strategies would provide about equal performance and power use if manufactured with same process. In real life, the single core part has to be made with a much more expensive process to run at twice the frequency of a dual core part. There are savings in die area because only half the number of transistors are required and because the transistors are smaller. Despite that, the 2 core part is still cheaper.

VW STUNS WORLD+DOG WITH REAL HOVER-CAR!

So many things wrong.

Effects that CGI artists might not know about:

They get really close to some other cars In the carpark, but none of them move or melt. No-one had coins or keys in their pockets? What about all the erased credit card strips?

CGI artists should know better:

Sometimes they drew a reasonable reflection on the windscreen. When driving along the pavement, they go from shadow into light, but this does not show in the reflection. Nor does the camera man. When the camera is right infront of the car, the reflection should spread out from the midline, not pan sideways across the whole windscreen.

The problem is that patent litigation is far too cheap

A plaintive should face a minimum entry fee of €100,000,000,000 per claim. There should also be a similar fine for the judge if he rules that a claim is valid.

Microsoft's dumpster-diver partner strategy is rubbish

Flocke Kroes

Microsoft's method

1) First rate is expensive, second place has hopes of becoming first rate so they are expensive too. Third rate knows they will never be better than third rate and will sell for much less.

2) Piss in the source code until is has some Microsoft flavour then distribute as a part of the operating system. In the past people would try to make do with the Microsoft offering rather than pay for something that worked.

3) When the competitors have been hit in the revenue stream, add some Microsoft extensions and make other Microsoft products depend on them.

Used to work fine, but now Microsoft has to compete with high quality free software. The first time that the Microsoft offering causes a little hassle, people try the alternatives. Making other products depend on extensions just puts those products in danger of being replaced. Only the thoroughly locked in stay with Microsoft, which is why the prices went up 30%.

Supersonic silent biplane COMING SOON ...ish

Flocke Kroes
Silver badge

The real problem with Busemann's biplane:

It does not generate any lift. A shockwave is created each time the angle of the wing increases. An antishockwave is created each time the angle decreases. Busemann's idea was to make each wing create an antishockwave at the point where a shockwave from the other hits. This makes the wings mirror images of each other - if one creates positive lift then the other creates negative lift.

If they have come up with a geometry that has no sonic boom but still creates lift then I would be really keen to see it.

Corner shops not in the same market as big mail order

I type a film title into mail order firm's web site and get a page of matching films with descriptions and prices. My local shop does not have a web site, if it did, the film would probably not be in stock and if it was, the number of customers does not justify the cost of entering the description so I would not know if I was ordering the right film.

Physical DVD shops have either diversified away from DVD's or gone bankrupt. Being unable to compete on price is only a small part of their problem. They cannot compete on convenience or range of stock.

Top Brit authors turn flamethrowers on barmy IPO

Flocke Kroes

If the governmennt does not want to pay royalties on textbooks ...

... they can hire an author to write a textbook. They could require their teachers to spend one hour per month updating a wiki that becomes a set of textbooks and pay a software consulting firm £130,000,000 per year to maintain the wiki. Plenty of solutions without resorting to copyright infringement.

By the way, ideas are not concrete objects. If the supermarket has 100 bottles of wine, and I steal 10 copies of each, and the supermarket still has 100 bottles of wine then the laws that apply to ideas could bear some relation to the laws that apply to property. Until someone can demonstrate such a theft, the term intellectual property remains an oxymoron.

The true, tragic cost of British wind power

Flocke Kroes
Silver badge

Worked example

Start with a Vestas V164 (really big) off shore wind turbine. 7MW installed capacity, 105 meter tall tower.

Pick a load factor - I will be generous with 33.3% so P=2.331WM average power output.

Pick a calm period - Europe usually gets five consecutive days of calm each winter. T = 5*24*60*60 = 432000 seconds.

Required energy storage is E = PxT = 10^11 Joules

Pick a height and depth: I will go for H=100 meters high and D=10 meters deep. The density of water is d=1000kg/m^3, and gravity (g) is a little under 10N/kg. The required area A is: A = E/Ddgh = 10000.

Water can be sucked up 10 meters - if you try to go higher, the water rises 10 meters and you get a vacuum above it. My pumped storage V164 has to take its mechanical power to the base of the tower, then pump water up into the 40 Olympic swimming pools supported by a forest of 100 meter tall towers.

In real life, transporting several MW of mechanical power 100 meters is not trivial, and you are better of converting it to electricity and back (75% efficient).

Linux PC-in-a-stick to cost coders £139

Flocke Kroes

$195 each

First attempt at getting a price came back with $195 each. If I go to the Pi forum, I am sure I could find some people interested in clubbing together to get a quantity discount. First thing I do with a new laptop is replace the glossy display and the spinning disk. Even at £125, a Qi display is about double the one-off cost of an ordinary LCD panel, and I like to go outside when the sun shines.

I am tired of getting burned for the cost of a whole laptop when all I want is a CPU/graphics upgrade. In the long run, I see this option saving me money.

A long piece of fishing line.

Nylon: Strength=78000000N/m^2, density=1150Kg/m^3. Gravity = 9.8N/Kg.

Mass of Nylon = (Mass of payload) * (length) * 9.8 * 1150 / 78000000

A 10Kg payload on a 100metre line costs 145g. Reliable real life figures are about double theoretical values, so 300g of fishing line for 9.7Kg of payload.

Resellers: Microsoft price hike was 'demanded by Euro country bosses'

Why do everything in one day?

I write portable code that uses cross platform libraries. Moving it to Windows or Mac requires only a little effort. Why haven't your 80 IT staff done likewise? Keep the interface constant and your 3500 users do not need to know what has happened.

Buy one new Linux server, get it to duplicate the work of one of your 3000 servers. When you are confident that it is doing its job, that frees up a high spec machine that you can install linux on to duplicate the work of two other windows boxes. Lather, rinse, repeat.

Or, you could keep buying Microsoft licenses and retrain everyone whenever Microsoft tells you that it is time to upgrade to the next big thing.

Demand for safety kitemark on software stepped up

Can we start by teaching Noddy level security to banks

1) I can have some confidence that https://halifax.co.uk/ is my bank. Anything like https://halifax-online.co.uk/ requires additional scrutiny, but that is exactly what they have done.

2) I can reduce the attack surface by disabling javascript, flash and java while shopping, but the few sites I found that did not require javascript now do.

3) I actually found a new site that did not require javascript. After I confirmed the order, I had to enable javascript to get to a verify by visa page. That page was from a third party site I had never heard of, so I assumed I had a secure connection to a phishing site.

Please can we cancel all banker's bonuses until they fix these basic security disasters. (What I suspect will happen is we will get some tax-payer funded adverts saying that only software with a Microsoft logo is secure, and a law requiring that all software used by the government must have that logo.)

Muscle chip strength leaves ARM shouldering meaty profit

Why would anyone care about Windows on ARM?

Legacy software won't run on ARM even with Windows (you could try wine+qemu-x86_64). It took ages for vendors to recompile for x86-64, so I would not hold my breath waiting for ports to ARM/Windows. Micronokia phones don't sell unless they are Meego. There is already plenty of software for ARM. Microsoft's only hope would be to require manufactures to lock the boot loaders to Windows.

WTF is... 802.11ac?

Flocke Kroes
Silver badge

Multiple antennas

At short ranges there are N signals. Each of the N signals are sent to each of the N antennas with a different delay. Each signal leaves the sender in a slightly different direction. The result is that the receiver gets a different signal from each antenna. N times the bandwidth.

At long range there is only one signal which is sent to each of the N antennas with a different delay. That signal is concentrated in the direction of the receiver. The receiver gets copy of that signal with a different delay from each of its antennas. It delays each copy by a different amount and combines them into a strong signal. The result is a directional antenna that improves the signal to noise ratio.

Government launches hydrogen motoring task force

Flocke Kroes
Silver badge

Electrolysis is expensive

Current nuclear capacity is near the end of its life, and there will be a gap before replacements are ready. We could use electricity from natural gas to create hydrogen but that would just make the coming power cuts worse. It would be cheaper to reform natural gas into hydrogen directly without converting to electricity as an intermediate stage. Even better, run cars off natural gas.

Most cars can have a natural gas storage added, and you can then switch between gas an petrol as needed. Gas storage is bulky so it does not has the same range as petrol, and the storage does cost some space. It is not for everyone, but it is tested and working technology (I used it decades ago in New Zealand).

The obvious reasons why this could never happen in the UK is it does not require everyone to buy a new car, does not provide a use for surplus wind power on windy days and does not require everyone to sit at home and freeze five days per year.

Boeing backs biofuel boffinry

Flocke Kroes
Silver badge

Compromise

Biofuels are made by collecting a little solar energy using plants, then adding lots of energy to convert plants into fuel. There are some numbers here: http://www.grist.org/article/biofuel-some-numbers Unfortunately that site does not go into detail about what energy costs are included in the calculations. I was using figures for corn, which I have just found out is abysmal compared to practical and profitable feed crops. That site has corn producing 1.5 litres of fuel for each litre used in production. If they have missed anything out, that could easily drop below one litre of fuel out for each litre in. Local processing reduces transport costs of the plants, but increases transport costs for the other raw materials and removes economies of scale. There are theoretical constraints. The sun is not getting massively more bright. Thermodynamics gives limits to the amount of energy you get extract from feed stock. While biofuels remain an insignificant source of energy, they can get cheaper. Go back to that site and look at yields per area and the amount of fuel that is used. Even using the most efficient plants, scaling up biofuel to replace fossil fuel will massively increase the price of farm land.

Terrible idea

The most efficient plants convert 1.5% of solar energy into biomass. The fuel required to transport biomass to a processing plant, covert it to fuel and transport the fuel to an airport is about equal to the fuel created from biomass. The fuel required to create and transport fertiliser and pesticides makes the entire process use more energy than it supplies. Abolish the subsidies and let this eco-disaster bankrupt itself.

Battery powered aircraft are technically challenging. They are possible, but do not have anything like to capacity and range of a fossil fuel powered aircraft. Investment in battery technology will close the gap a bit, but I suspect the real place to invest is in converting CO2 + water into fuel using chemical reactions and nuclear power.

By all means put solar panels in the deserts where they can be cost effective and do not compete with agriculture, but do not expect them to make a significant contribution to the energy budget. Wind and solar power proposals always include a statement like: this project will power X thousand homes. What they mean is X thousand homes with gas central heating, gas hot water, fossil fuel transport and fossil fuel agriculture. For real numbers, divide the claim by something between 5 and 10.

There is a reason why the world is powered by fossil fuels and nuclear power - those are the only two that can scale to meet demand.

Apple land-grabs fuel cells for mobiles

Flocke Kroes
Silver badge

Prior art predates the register

Older readers will remember when video was stored on mag tape. There was a TV program called Tommorrow's World that covered the pocket calculator, mobile phones, jam covered CD's and fuel cells. All of this predates the standardisation of TCP/IP.

Fuel cells where expected to power mobile devices because the devices used much more power than modern toys and the batteries were not as good either. It proved challenging because the catalysts were expensive (modern manufacturing techniques allow massive reductions in the required amount of platinum), also storing hydrogen was difficult (still is), other fuels poisoned the catalyst, oxygen supplies are inconvenient and air poisoned the catalyst.

Fuel cells were used on the space shuttles. (The space shuttles were re-usable manned space vehicles - honest - you can see 3.5 of them in museums). Space shuttles had liquid hydrogen and liquid oxygen for their rocket engines. The price of the catalyst was only astronomical, and the waste product of the reaction - water - was handy to prevent the astronauts from dying of thirst. I am not old enough to have watched the first man set boot on the moon. If the patent system continues as it is now, then I did watch the last.

If things go as I expect, we will get some standardised battery sizes which Apple will not use. If fuel cells ever become cost effective, they will come in standard battery sizes and be fitted as an after market upgrade for phones that are not welded shut. Apple can defend their fuel cell patents the way Edison's Motion Picture Patents Company defended theirs.

Iran spy drone GPS hijack boasts: Rubbish, say experts

Flocke Kroes
Silver badge

All correct, and ...

Stone age GPS units had a tiny number of correlators and antennas that rejected left hand circular polarised signals. The satelites transmit right hand circular polarised signals, which get reversed if they reflect off something. Reflected signals arrive late, and made the GPS units report a position further from the satellite than reality. Also, when first switched on, the GPS would pick two satellites on opposite sides of the plannet, divide the correlators between those two, and give each a different guess at the time delay. If they found nothing, they would try other guesses or other pairs of satellites until they eventually guessed right.

Bronze age GPS units had lots of correlators. They could assign dozens to each satelite and find them from a cold start in seconds - unless the satelites were hiding behind buildings.

Modern antennas accept both left and right hand signals. This allows the GPS unit to get a signal when the direct path to a satellite is blocked. Modern GPS units expect to spot the satelite signal and multiple reflections of it. They assume the earliest signal is the right one, and the others are reflections. This allows them to remain locked on even if a satelite is temporarily hidden. Even if the GPS does lose its lock on a satelite, it has hundreds of correlators available to get it back again in under a second.

If you try to spoof a modern GPS, it will have enough information available to know something is wrong, but may not be programmed to recognise the problem or do something sensible about it. After all, the Americans know beyond all possible doubt that spoofing will always be well beyond Iran's technical abilities no matter how much GPS technology has changed since the first attempts to spoof them.
