Milky Way DOOMED to high-speed smash with Andromeda galaxy

Flocke Kroes Silver badge

Galaxies in clusters

Milky way, Andromeda and about 50 small satellite galaxies make up the local group. These are all so close together that their gravitational fields affect each other. The local group is part of a cluster of groups of galaxies. There are many clusters of groups. Galaxies inside a group orbit the centre of mass of the group. The distance between clusters increases with the expansion of the universe.

Take a look at the diagram at the end of: http://en.wikipedia.org/wiki/Local_Group

Third-gen Ultrabooks must offer USB 3.0, anti-theft tech

Wrong BIOS password - really scarey

Some kind person just enters "password" 5 times and my expensive new ultra-book is broken. I think I will just stick with computers that are so cheap that they are not worth nicking.

Flocke Kroes Silver badge

"Chip level" is not an answer

Does "not make any difference" mean anti-theft activates when a thief or I swap the OS or hard disk, or does it mean anti-theft does not activate when a thief or I change the OS or hard disk? Is there some kind of naughty or nice detector that decides who has changed the OS or hard disk?

Flocke Kroes Silver badge

Anti-theft tech?

If a thief wipes the hard disk and installs a pirate copy of Windows, is the anti-theft tech wiped too?

If I wipe the hard disk and install Linux, does the anti-theft tech activate?

Cut & Paste

The first time i used XP, I found that the middle mouse button did not work (as expected). Luckily the machine's owner was near by to explain that paste was Ctrl-something-I-have-forgotten. The usual default Linux settings are:

Left click: Do what I usually mean.

Left click and drag: Select for pasting.

Middle click: Paste.

Right click: Show a menu with less commonly used choices.

Alt-left click & drag: Move window - handy if the window is bigger than the screen.

Shift right triple click while singing the Monty Python spam song with your left knee behind you ear: Not normally assigned but I am sure someone will thing of a suitable use.

Nokia Lumia 900 WinPho 7 smartphone

Flocke Kroes Silver badge

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.

MPs: Unified EU patent court framework would hurt small biz

Flocke Kroes Silver badge

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 Silver badge

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%.

NAO: 1 in 5 of Whitehall's mega projects at risk of failure

The easy way to avoid failure is to avoid defining success. If you can avoid measuring the initial problem, so much the better.

Fitting an SSD as standard is far beyond the ability of too many manufacturers. If you want to keep a reasonably wide selection, expect to buy your SSD separately. Add a USB enclosure for the surplus spinning disk and you have a backup device.

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.

Microsoft hikes SQL Server 2012 price 'by 20 per cent'

Flocke Kroes Silver badge

Microsoft can do better than that

Major releases are three or four years apart and they say with a 20% price rise this one pays for itself in 12 to 14 months. We should be looking at prices of between two and three times current levels to get to the break even point. I am very disappointed.

High Court asked to keep 'cheap DVD' VAT loophole open

Flocke Kroes Silver badge

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 Silver badge

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 Silver badge

$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

Flocke Kroes Silver badge

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

Flocke Kroes Silver badge

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.

Three challenges for you

1) Describe an experimental setup demonstrating LENR that gives results others can repeat.

2) Measure significantly more decay products than the background level.

3) Measure significantly more heat output than calorimeter calibration errors.

If you ever achieve all three, I will apologise for saying LENR is an investment scam.
