"You know, for a club that sold itself as "socialists", New Labour have engaged in some serious mowing down of human rights when they were in power.. Makes you wonder what they had to hide that they were so enthusiastically expanding the surveillance state.."
You may remember that they were selling themselves as the "Third Way" - nearly fell out of my chair when I heard that one
Arthur Moeller van den Bruck was going to write a book entitled the "Third Way". But he changed it to a much snappier title in the end. Which inspired a generation. And how.....
The pertinent bit
"One day, high above Arizona , we were monitoring the radio traffic of all the mortal airplanes below us. First, a Cessna pilot asked the air traffic controllers to check his ground speed. 'Ninety knots,' ATC replied. A twin Bonanza soon made the same request. 'One-twenty on the ground,' was the reply. To our surprise, a navy F-18 came over the radio with a ground speed check. I knew exactly what he was doing. Of course, he had a ground speed indicator in his cockpit, but he wanted to let all the bug-smashers in the valley know what real speed was 'Dusty 52, we show you at 620 on the ground,' ATC responded. The situation was too ripe. I heard the click of Walter's mike button in the rear seat. In his most innocent voice, Walter startled the controller by asking for a ground speed check from 81,000 feet, clearly above controlled airspace. In a cool, professional voice, the controller replied, ' Aspen 20, I show you at 1,982 knots on the ground.' We did not hear another transmis sion on that frequency all the way to the coast."
Hydrogen powered cars are actually electric cars....
They have a fuel cell instead of a battery - that is pretty much it. In fact Hydrogen powered cars may well have a small battery to smooth out power spikes and for storing power from regenerative braking.
Refueling is an issue with Hydrogen. If you are using cryogenic hydrogen, then you can't pour it fast. If you do, lots of boil off. Then you have to cool the system down to take the hydrogen. Liquid hydrogen on room temperature metal - no no. Then you have to purge the lines of air.
It all can be done. But the idea you will slop the hydrogen in petrol style is sadly not true.
So the question is whether the inconveniences of hydrogen will outweigh the inconveniences of batteries.
IMHO it looks like there is more room inside the laws of physics to improve batteries...
If you want to bring stuff back from ISS, you use either Dragon or Soyuz. Those are the only options.
A very mangled version of what happened
NASA started by sole sourcing their cargo transport to the ISS to Kistler, who were developing a two stage reusable launcher.
Kistler by this stage consisted of a lot of ex-NASA people who outsourced all the actual rocket stuff to various giant aerospace companies. Costs escalated and delivery dates rolled to the right in traditional aerospace style.
SpaceX filed a protest about sole sourcing the contract - federal law mandates competitive bidding except in certain circumstances. After winning, their bid won - along with Kistler. So, a two horse race.
Then Kistler ran into a slight problem. They ran out of money before actually finishing anything. They couldn't find the half billion dollars they needed to actually build something. So they went bankrupt. Note that the extra money they needed to finish was far more SpaceX (or Orbital) spent in total on their systems.
So down to one bid. So NASA made some noises and Orbital came up with their bid to be the second supplier. And got a better deal (more money for less stuff) than SpaceX, by the way.
Both Orbital and SpaceX have only received money form NASA in competitive contracts based on actual work done.
To many (like me) the bankruptcy of Kistler was a sign of why the COTS program was a better way to go - I you fail, you fail. What a shame. Not.
The Ares I project collapsed due to the fact that the stupid design wasn't fixable - the vibration from the solid first stage ranged from I-cant-see-the-instruments (really!) to Ive-been-shaken-to-death (literally). By the end of the program, it couldn't lift an Orion capsule all the way to orbit because of the weight of the shock absorbing systems required to reduce the vibration. Not to mention an 18G escape tower system that used a rocket the size of an IRBM to... fail to escape the debris cloud if the first stage went boom...
Re: Twas ever thus
Ironically, the education establishment is up in arms over the Free Schools precisely because they aren't identikit sausage factories.
The dirty little secret about Comprehensives is this - the few that get their pupils into the top universities regularly use the "Evul Private School" examining board A levels.
Funny how no-one has noticed that.
We have Secondary Moderns right now. It's just that they don't label them that way.
Re: Sauce for the goose
Some years ago, a US trade delegation deliberately said some things in a location that they suspected was bugged.
The French government was actually upset when it turned out it was a deliberate setup to stuff a French company.
Re: Someone has has missed the plot
NIce try - but, no, I don't own one. Not an early adopter. I know a couple of people who do, though.
The battery on the Model S was designed to be swappable - not just replaceable - this was mentioned before and during the launch.
If you want to be able to swap a 1/2 ton in/out of a car by robot, it has to be designed for that. Doing it so that a mechanic can do it it in a couple of hours would be be a completely different problem in engineering terms.
The data on battery wear from the Roadster is interesting, by the way. Looks like a temperature controlled battery with decent charging control does some quite interesting stuff for battery life. Something on the order of 1.5% per annum degradation, apparently.
Someone has has missed the plot
Aside from there being a rather long waiting list to buy their cars, and they are increasing production....
I find it rather interesting that everyone on this thread has not noticed that the Model S was engineered from the start to have a swappable battery. Which was mentioned at the launch of the car....
Re: Sit back and let the comments roll in
The staff (and their behavior) are largely a function of the company and it's policies. When Woolworth's was on the local high street, the staff looked appalling - like zombies. Must have been hell to work there.
Waitrose took the site. Some of the same people work there - now look like humans.
One reason that John Lewis is doing so well is not the employee ownership thing (directly). It's that their sales staff aren't on a commission structured to flog you stuff you don't want and they are encouraged to use their initiative to solve customer problems.
In Dixons, going off the required sales script is a "BAD THING". So you end up with a store full of people who aren't interested in what they are selling, just flogging guarantees etc. They are being paid to do this, recruited to do this, told to do this........
In John Lewis customer satisfaction is their company goal. So you end up with someone who tries to help you get what you want.
Re: Fossil fuel isn't taxed?????
What you need to talk about is the "well-to-wheels" cycle. Petrol doesn't just appear in petrol stations after all.
When that is considered, electric vehicles are the equivalent of high miles-per-gallon vehicles - a Tesla Model S get 89 mpg (equivalent), according to the US EPA and the Leaf gets 112 mpg
That's for charging of the US grid....
Re: Half that number
Interestingly, Roadsters owners report a much lower degradation rate than the quotes spec.
Which is what you would expect - you would leave a considerable margin in a product.
The reason for this is that the Tesla battery system uses non-bleeding edge cells and is very nice to them - monitored, controlled charging, heating/cooling to keep the temperature stable etc.
Most peoples experience of Li batteries is in mobile phones and laptops. The car equivalent of how they treat the battery would be to empty your radiator and do doughnuts and smoke your tires every day.....
Re: When did?
Mind you, back then, when they made archery - with specified military grade arrows and bows - compulsory, they banned football.
Too dangerous, apparently..... Seriously, football was then a two sided riot for possession of the ball. Deaths were common. No, wait....
Wonder what happens when the first time someone uses a coil gun for Bad Things?
In wheel motors have a serious problem - they add massively to un-sprung weight.
Batteries suck as crunch zones - dense, solid.
The evidence on battery life seems to be that treat the battery decently - controlled charging to a profile, cooling to prevent temperature excursions etc - massively extends electric vehicle battery life compared to the lig=fe span of a laptop battery.
Bingo - remember that Tesla had a problem with the crazy torque from a high power electric motor destroying the best gearboxes they could find....
The big issue for electric cars is battery capacity. Real world data from Tesla and others shows that battery life is much better than you might think - intelligent charging systems that don't brutally trash the battery, they way that your laptop or mobile does....
With battery capacity up to say 500 miles on a single charge (probable within the decade), the issue about charging time goes away.
So you are left with a mechanically simple vehicle that can a 911 at the lights....
Re: British Intelligence
Much of it was down to the fact that Admiral Canaris (head of the German Secret Service) was probably working for/with British Intelligence.
Re: good to be able to look on this so light-heartedly
Small towns in Germany are 20Kt apart....
Re: Good Show ol' chap
I remember a visit to Nepal. A camp site that was literally in a shit state. Hip touristas managed to whine about it, but did nothing.
A British army group arrived - officer cadets in the charge of an RSM straight out of Zulu. Apparently they were touring round the country to actually learn about it. Said RSM looked around and said "Right". or something to that effect. And went to talk to the locals about what they reckoned was the solution.
24 hours later, when they left, a functional outhouse had been constructed from dry stone walling. Built by the cadets. And the er.... problem tidied up a bit.
The right out types were still hating on the evil military. While using the outhouse.

Double precision support is the big difference for the commercial cards
Re: Seen elsewhere
Incidentally the titans of the civil service "planning" wanted to discourage all this mucking about with "toy" computers. They wanted British industry to concentrate on the main frame market where all real computing is done.
There is a hilarious minute of a meeting that was published a while back about how Maggie et al didn't understand that home use of computers was pointless fad that would obviously never go anywhere and that companies needed to be "redirected" in the "national interest"
Re: Where lawyers go to die - or at least smell bad
To be fair to layers (not something I do on a regular basis) a law degree will be seen as useful and work related in many jobs which are not actually being a layer. Essentially you will be seen as having studied something serious and potentially useful.
One part of this that doesn't get mentioned enough is this. The cry that "everyone must go to uni" was based on the idea that they is no industry in this country so everyone needs to get a white collar job. Ironically, there are very large numbers of "blue collar" jobs in the UK and many are now paid far better than crappy white collar jobs.
These "blue collar" jobs require skills and training. A degree from a second rate university in something bland isn't much help.
We are being trapped by a pre 1950 view that getting on in life means getting into an office. Otherwise you end up shoveling coal or something.
Re: Tesla: the ultimate in man Maths
Which is exactly the kind of investment required to design some cars and setup a car factory. Which can produce 10 of thousands of cars. *Per year*....
In fact that is pretty cheap by motor industry standards.
Re: Leccy? No!!
Fuel cell cars are, in fact, electric cars.
Electric motors. Check
Regenerative braking for decent range. Check
Battery to support regenerative braking. Check
Fuels cells are best thought of as an interesting kind of battery
Re: Secret payload
Besides, they duct taped him to the inside of the interstage....
Re: contingency plans
Have you seen some of the Funky Fun things that Soyuz and Progress do?
My favourite is the orbit module on Soyuz not detaching, so that Soyuz re-enters the wrong way round. Apparently the astronauts get to see the hatch seal starting to smoke, before the orbit module burns off and the Soyuz does an instant 180 at 15,000mph+. This has happened twice.
Progress has numerous incidents on the way to the station. Computers up and down like a merry go round...
As for NASA - the Shuttle program was full of near misses. Look up STS-27
Some years ago the Economist crunched the numbers on gang members in LA.
Working at McDonalds would have doubled their take home pay.....
Re: GPS technicalities
1) The Amerixcan military moved away from degrading the unencrypted signal on GPS years ago. The unencrypted accuracy is the same as the encrypted. The limit is pretty much physics now.
2) They have actually removed the degradation feature from new satellites added to the constellation - as the older satellites go out of use, this option becomes less and less possible.
3) The reason the Q code is encrypted is not secrecy. It was assumed when GPS was designed that the Russian equivalent would be up and running rapidly. The Q code is there to make it harder to jam (lock on the signal when jamming is actually louder than the signal - think listening for a known tune) and to make it very, very, very hard to spoof (you would have to know the code to broadcast a fake signal).
Re: extradition of an Australian citizen from th UK
None of the potential charges carry the death penalty in the US.
Shipping him to Gitmo can't happen either - the whole point of Gitmo is as an end run round the judicial process. If he gets extradited to the US he goes into the judicial system on landing.
There is not the slightest evidence that Sweden would extradite him to the US.
The suggestion that Swedish prisons are too awful to contemplate is hilarious. Prison reform movements around the world use Swedish prisons as an example of how it should be done.....
JWST has eaten all the money. Bet you that the James Webb telescope management are trying to put these sets of optics on eBay as we speak.
So if there is no public interest defence, should the following be prosecuted?
1) Everyone involved in Wikileak?
2) The Telegraph be prosecuted for releasing details of the MPs expenses.
3) The Guardian - they admited phone hacking an Evul Oligarch a while back. They also released the Assad emails....
4) Any MP who has received leaked government documents?
5) Amnesty International often releases documents that aren't theirs.
All of the above have either carried out, encouraged or been complicit in technical breaches of these laws.
1) Android is going to end up on a lot of phones - basically the none Apple ones. Microsoft is going to bob along at the back with a small amount of market share.
2) Apple's computer business is based on having the majority of the high-margin business. Most of the PC business is selling a wafer thing margins.
3) Apple caused/prompted a massive take up in smart phones and tablets that spread usage of both a long way outside the usual niches for such products.
4) Everyone else is following the Apple lead in these two areas.
5) It is assumed that Apple won't make a mid/low price offering in these two market areas. But what did they do with iPod?
All of the above strongly suggests that Apple with be a declining percentage of the phone/tablet market. But they will probably have quite a lock on the high-margin part of the business, and probably record massively growing sales in absolute terms for the next few years.
As tech marches on, there will be point where iPhone/iPad "Mini" offerings will make sense - sufficient performance on a cheaper device. We have also seen, to date, the results of attempts to build cheapo tablets...
If you read the history of the MP in question (google) you will see that appears to be one of those people who should stop drinking at all.
The other question is why the prices in the Commons bars are so subsidised, given the joy with which they like to legislate for the Outer Party and The Proles.
Most dinosaur remains are distorted by the fossilisation process - wonder if they are going to reverse this?
For those who don't know the politics - JWST is un-cancellable, lots of work in the state whose senator is a key senior Democrat.
Commercial crew is being cut back because the backers of Orion/SLS are worried that if 2 or more crewed vehicles are ready before the first (unmaned) flight of Orion, it will be killed. So the pressure is on to down select to a single vendor and delay it until Orion is in service.
Anyone making stupid comments about "the colonials" government should consider BAe, Westlands etc - billions for crap. We do it to - and end up with less. For more.
When politicians control buying and selling, the first things bought and sold are politicians.
This is why Ancient Greek history is so valuable - check out how the Parthenon got built.

Slab Murphy is probably doing it now.....
You have solar panels that live forever? And the converters etc?
If solar panels were essentially free (and the electronics) then what you say would be true. But they aren't. Yet.
It is interesting that Apple have adopted the non-commission policy. This policy is used by John Lewis - it is the main reason that so many people find shopping there so pleasant. In most other retailers, there is a hideous push to sell. Yes, Dixons/Currys, I am looking at you.
Talking to sales staff at John Lewis, many of the older ones have moved there from other retailers. Their happiness to have escaped the pressure sales thing is one thing. They also uniformly comment that they sell more, simply because they are free to connect the customer to the things they actually want, rather than the managers-push-of-the-week.
The fun bit is that this rocket is primarily used for US government payloads.
Yes, Russian engines used to launch American spy sats....
Mind you, Russian strategic missile subs use GPS for navigation....
But the basic ideas do work -
1) a couple of pages.
2) reverse order - last thing you did first.
3) summary of you and your skills in a paragraph at the top
4) contact info. at the top of page 1
5) these days - work permit/nationality stuff at the top as well.
The best thing about the "re-write your CV our way" thing is seeing the different takes on your original - how other people see what you've written....
I think that many people missed the weapons grade sarcasm in the original article.....
The energy isn't the problem
To raise the Earths temperature just by adding heat would take an insane extra amount of power - think multiply world energy expenditure by 100x to see noticeable effects. This is because the heat radiates away. You'd get some heat islands (see modern cities).....
Green house gases are about accidently installing extra double glazing and keeping unwanted heat in. Not the heat itself.....
Basic physics 101 -
You can't build an orbital death ray with microwaves, unless you used a antenna of insane (100s of kms) dimensions. Easier to build a small antenna and allow bean spread. Just cover x amount of farm land with chicken wire on poles. Land is cheap in this context
The best scheme is to use a phased array antenna for transmission which is locked onto a pilot transmitter on the ground. If the orbital antenna looses lock, all focusing would be locked and the power per square whatsit would go down from less-than-sunlight to I-need-a-better-detector-to -detec anything.
It is useless as a weapon - "Do as we say or we will turn our beam of microwaves on you. At an intensity that is classified as safe for the workplace by 'elf and safety".
7 tons of hydrazine on that thing.
USA 193 had about 1/2 a ton
"Captain of the USS Lake Erie to the courtesy phone......"
Apparently he admitted to his (civil service) boss that "he exceeded his authority". In a minuted meeting.
I think that is a fairly epic way to fail.
You can imagine why he is trying to fight that now.
...was in the Conservative Manifesto for 1945. The NHS was planned under the wartime Conservative led coalition.
There were two structures suggested in the original reports. One was to nationalise everything. The second was universal health insurance, with some government facilities - the model that most of the rest of the present day first world uses.
Labour went for plan A. The Conservatives were going to go for plan B.
Cyber warfare has already happened -
The Israelis switched off (parts of) the Syrian air defense network, then bombed the hell out of the Syrian copy of the North Korean plutonium producing reactor... According to rumour they switched the systems back on as they left Syrian airspace...
The point being that it will be one of the weapons used in future conflicts. A "cyber only" war is unlikely.
