Yes, yes, all very well for dealing with intellectuals, but tell that to Al Capone and his ilk.

No sir! These people are not letting off bombs in our midst because of a rational analysis of British foreign policy. They do it because they hate us; they hate us because we do not embrace their specific religion.
We cannot repeat often enough that in Britain secular law takes priority. If they really cannot accept that, it is time they moved, or are moved, elsewhere.
Many of the techniques used in statistics can be mastered with practice, even by a social sciences graduate if they are willing. But the proof of these things is often extremely difficult: for example, that a binomial distribution with large numbers tends asymptotically to a Gaussian distribution.
Stats therefore becomes a memory test, since it is difficult to re-prove a theorem that has slipped one's mind.
But the numbers calculatated in this case for a chi-squared test probably are more or less chi-square distributed.
If one assumes a binomial distribution of the raw figures. they deviate by two standard deviations from a 50-50 result. The probability of a deviation that size or more is roughly five percent.
As I understand it, the pollutants are oxides of nitrogen. These are produced when things are burned in air at high temperatures. This is a problem for diesel engines because of their high compression, hence high adiabatic temperature rise. This makes them thermodynamically more efficient than petrol or butane engines, so they use less fuel. So they produce less CO2, but more NO/NO2.
We have catalytic converters to turn CO to CO2; higher combustion temperatures yield more CO. But it seems there is nothing to remove the NO/NO2.
But you are right that CO2 is not a pollutant: it is plant food; and the regulations are designed by green freaks, not scientists and engineers.

It was Colossus that emulated the Lorenz machine; the Bombe emulated the Enigma machine. If I have correctly understood the tour guides at Bletchley and TNMOC, the aim of both machines was to find the rotor settings, i.e. the crypto key.
This was done by testing "cribs": guesses at typical message headings, date and time, etc. Colossus/Bombe used two paper tapes, one with the encrypted message and the other with the crib. C/B tested many, many key settings and displacements of the crib from the start of the message.
The original Enigma message was then transcribed on a Typex machine, a British "Enigma" modified to mimic the original Enigma. As pointed out above, there were numerous variations of the Enigma.
Equally, there was a pseudo-Lorenz machhine. The Lorenz machine was a weighty beast, fit only for a headquarters role. The Enigma was portable.
But Turing wanted Colossus built to crack the Lorenz machine traffic on a large scale in a timely way.
The Enigma traffic was handled by one or more of The Bombe, an electromechanical beast.
Both machines used continuous loops of paper tape in the absence of computer memories.
In my experience as a political activist in the UK, the political parties are the only organisations that take the Telephone Preference List seriously. That is the list of people who do not want unsolicited telesales calls.
The parties know that an unwanted telephone canvassing call will lose them that vote.
Politics is not a glamorous business and it has many critics who would not "dirty" their own hands. You look at some UK politicians and think, yes, they do reflect the less appealing elements in our voter database.
But the alternatives are a lot worse. Dealing with people, and all the faults that people have, is not an easy task. It could be argued that President Trump is an example of what happens when a businessman rather than a politican is elected.
I spent my career wondering how to turn science and engineering graduates (whom one would expect to think logically) into competent programmers. That is, produce programs which handle correct cases correctly, and error cases with error handling that does not crash. Programs which were tested to see whether they fail, not whether they barely scrape through a cursory test or merely compile.
Those skills cannot be imparted by management.
I never did find the answer.
I was once asked to look at an aircraft simulator that was supposed to run 20 iterations per second, but the first version took 2 seconds per go. By rearranging the maths I got it going at 10 times per second. No need to resort to assembler.
So this kind of work needs numerical analysis skills as well as programming skills.
I am not eligible for this NASA job: (i) I'm a Brit (ii) I'm retired, and would have to be very tempted.

What kind of democracy is that? Why should techies, rather than (say) religious nutters, be allowed to impose their values and standards?
Nobody should be allowed to impose. Even a democratic majority must accept some limits, but minorities should accept their minority position.
In this democratic people's monarchy of the UK, the non-techies vastly outnumber the techies.
The non-techies have been demanding for a long time that internet pawn be stopped, and the techies should stop whingeing and stop the pawn. The techies respond that it is like asking Newton's Laws to be repealed, but that is democracy for you.
In real politics, of course, there would be a sensible compromise. E.g. if you really want to watch pawn, smoke cigarettes, or drive a car you pay extra tax and extra extra tax if you pay anonymously.
Everything has its price.
Since it recognised my normal setup with all its fonts, I tried two small Linux systems that were a standard CD image, no further installations or changes.
1. System Rescue Disk v4.1 + Midori browser. Could not connect to site, SSH handshake failure.
2. Tiny Core Linux + Firefox v52. I am in 26 out of 10,000+ users.
So to be anonymous, use a small Linux system.
A lawyer in England, where libel laws are strict and therefore disliked by idle journalists, could argue that calling a patent stupid is an opinion rather than a claim of fact. As a mere opinion, it is not defamatory.
Defamation might be, for example, to claim the patent was based on plagiarism or obtained by bribery.
I am surprised the Australian judge did not take such a view.
@tiggity
Indeed they were. The hatchet job on Dear Old Boris must rate as one of the most vicious in history.
There was then a series of votes, eliminating the candidate with fewest votes until there were two. Even I find it hard to remember the unsuccessful names; but some will have been staking out a claim to a place in a future contest.
May versus Leadsom as the finalists; then Leadsom withdrew.
So the Enceladus probe has discovered the ingredients that went into the famous Miller experiment of 1953: hydrogen, and hydrides of carbon, nitrogen, and oxygen.
The outputs of the Miller experiment were relatively simple organic compounds, but a long way from the highly organised large molecules of protein and DNA.
The news from Enceladus is an encouraging start, but nothing to get excited about. When the metal-digesting microbes there start chewing up Cassini's equipment, that will be news, if the reports get back to us.
"...Microsoft wrote a stub to detect whether OS/2 was installed..."
Windows 95 was distributed to end users as an "update CD". It would not run unless it detected an installed Windows 3.x or was presnted with the first W3 floppy disk. It would also accept the first OS/2 Warp 3 floppy disk.
There are other variations of that quote about five computers: e.g. the UK would only need that kind of number.
For the publicly known computations of that time - gunnery trajectories etc., that number is perhaps right. But I believe over a dozen instances of Colossus were built for code cracking. So even then the estimate of five was way out.
However the real expansion of computing came with data processing, where record keeping outweighed the relatively small amount of computation. IBM should have known that, given their existing business in accounting machines fed with punched cards.
The big defect in OS/2 that I met was the lack of a stop button in any window. Yes, you could close the window but that did not stop the task, just left it sitting in the background.
It was Windows 95 that brought us a proper stop button.
We had an OS/2 system returned to us as not working. The user had been closing the window, and then later starting up another instance. The system was clogged with dormant tasks. Once I removed them, everything worked again; what we had to do then was to update our User Guide.

I have tried various releases of Reactos, up to 4.4. It is still beta software at best, and is unhappy on real hardware rather than a virtual machine.
After my last attempt on real hardware I had to wipe the bios with a specialised program to restore the normal ability to manage bios settings.

Within reason (that typically British phrase) I can live with being spied on by the authorities. What I strongly object to is being spied on by the usual suspects: Google, Microsoft, Amazon, ...
I get the impression that American preferences are the other way: they allow almost anything from corporates but not from government.
So much for the Internet uniting the world. It actually shows how divided we are.
As a Brit, I like our way of doing things.
THEY make the laws but WE decide whether to obey those laws.
Germans have a very different attitude. Germans have said to me, the law is the law and should be obeyed. Somehow the USA has taken up that German position rather than the English one. Revolutionary animus, perhaps.
@man who fell...
Such a witness can then be branded as unreliable by lawyers for the other side, thus weakening somebody's case. Actions or inactions have consequences.
We live in organised societies that are more then just a bunch of selfish individuals. So individuals do not have absolute freedom. In common law states - Britain and USA - there is a common law duty to assist in mantaining law and order.
Too much technical policy in Britain is decided by campaigners with limited scientific knowledge but who have the ear of our arts graduate civil servants.
Not only is the campaigners' knowledge limited but their scientific judgement is zero. They should be called technicians, not scientists.
@Mage
Well said!
I partly blame modern education, which tells children to be creative rather than to check their work.
Also, nobody wants to pay for quality, and they expect bug fixes as part of the service.
In my own programming career, I saw many poorly defined interfaces that did not logically separate various aspects of the requirements. It is difficult to get a poor interface working free from bugs.
