The shortage of people meeting the requirement "Must have 10 years experience with technology X which has only existed for 5 years" has now become so serious that even H1b's can't fix it.
Must think "outside the skull". (Personally, I suspect zombies would be a good choice for the HR department. Unlikely to be worse than the current lot).
a German city recently banned Diesel cars from certain areas and air quality got WORSE
I am not very surprised. The issue of air pollution is more about politics and propaganda than science. The VW "scandal" being an example. The regulations did not specify emissions while driving the car, they specified the emissions in the lab. That is the same as saying "we require X performance in a benchmark" - ie virtually a request to game the system.
The problem now is that people are being driven to
Petrol
Diesel with Urea injection
Petrol produces "Oxides of Nitrogen", (which are popular with certain people for "boosting their heart", and have a half life in minutes) but they are removed by a catalytic converter. Petrol also produces unburned hydrocarbons ("Volatile Organic Compounds") - which are known carcinogens.
Older diesel engines do not produce oxides of nitrogen, because they do not have high enough combustion temperature. However, they tend to produce soot (which is known as "activated carbon" in other circumstances). It looks bad, but probably does not do much harm. It could be removed with a particulate filter, but older diesels don't have a filter.
Newer diesels use urea injection to mitigate the oxides of nitrogen. They squirt "AdBlu" into the exhaust pipe. How much AdBlu is needed? well it depends on the instantaneous temperature and pressure during combustion - which you can't measure or guess on the basis of fuel burned. So its a wild guess. Too little, and you get oxides of nitrogen, too much and you get urea in the exhaust. The manufactures of AdBlu (which is basically pigs piss) get lots of your money.
A lot of the pollution from vehicles is particulates from the brakes and tyres - which is probably far worse for you than the items mentioned above, and is worse with electric cars because they are heavier.
The charts show that all pollution from vehicles in Western Europe has been falling steadily since the 1970's, as has pollution from most other sources. Not sure about the rest of the world. Figures for "deaths from pollution" are pretty much all made up. I am not saying there aren't any - only that no one has "cause of death: pollution" on their death certificate, and therefore _numbers_ are not based on actual evidence.
If it was down to me, I would recommend diesel engines with exhaust gas recirculation and a particulate filter. These run slower than the Urea Injection engines and avoid the very high temperatures that require urea injection. This means they are slightly larger and heavier, and have a longer life. They may also have marginally lower fuel efficiency. Needless to say, its not up to me. As with most things today, we have to have a disaster before anyone will want to know the truth.
Disclaimer: I have not worked in the auto industry or anything connected with it, but I have built my own cars and engines, and know a thing or two about diesel engines and combustion.
Here in America we've agreed centuries ago, that allowing government to judge, what is and what is not true, is more dangerous than an occasional falsehood slipping through.
Possibly, but consider:
You in America may have this view, others do not share it.
it is not the "occasional falsehood" it is torrents of the stuff sent for the purpose of inciting hatred
Your government may be a pile of shit, other people's government may be better. The reason your government is likely a pile of shit may be connected to the fact that is elected on the basis of a ton of politically motivated lies.
See also Ministry of Truth [enotes.com] â" which is what you'd like established to go after these "rumour mongers".
No. I do not want a "Ministry of Truth", you are dishonestly misrepresenting me for the purposes of propaganda. There are ways to establish the truth (many countries have law courts for this very purpose). I would like to see a legal system with powers to punish people for deliberate and wanton lying for political purpose or financial gain. Yes, you would be convicted under such a system. You'd best stay in America. The rest of the world would prefer America stayed out of their business.
Yes, I am European. I don't have a maths degree. I can and have fixed plumbing/airconditioning/electrical systems, have dug wells and driven trucks for a living. I can use wood and metal lathes, milling machines and gear hobs. I can and have sewn clothes for all the family. But I cannot play bluegrass or clog dance.
You, OTOH, have drunk far to much kool-aid/moonshine blend.
degrees that did nothing to prepare them for the job market.
In "the good old days", University was not about getting a job - it was about learning about civilisation, plus a bit of specialisation. If you wanted to "learn a trade" you got a certificate, or diploma (HNC, HND, City & Guilds) this meant you knew how to do a job. A degree at a University meant you understood the theory, and, as everyone here probably knows, in theory: theory and practice are the same, In practice: they are not.
However, one of the advantages of democracy is it give the votes to illiterates - who know neither theory nor practice, and vote for Brexit/Trump and "everybody needs a degree to get paid what people with degrees are earning".
Obviously, if the Universities select the 15% most academically minded of the population, they can teach them to a higher standard, than if they have to accept 50% - which implies accepting people with below average intelligence, since some of the more intelligent won't go to university - have dropped out to start million selling businesses, or become rock stars, or take drugs. If a degree no longer implies above average intelligence and education, why would it imply above average pay?
To the employer, a degree no longer guarantees someone with above average intelligence and education, and possibly comes from "the elite" - it implies they have a piece of paper and a lot of debt, and tells you nothing about their social background.
As an employer, I would set more value on someone who appeared bright and determined on the basis of stuff on their CV, and having the determination and will-power to avoid being forced into debt (except for certain types of knowledge - eg: a maths degree from a reputable university still probably means something).
You can blame the person sending the info, or the person originating, but not the medium.
If someone poisons the water supply, the water company may not be to blame, but if they don't shut off the supply of poisonous water, they are to blame for that and the resulting deaths.
America IS to blame for assuming the rest of the world has a "right to spread lies" rather than a tradition of punishing rumour mongers - who are often inaccessible because they hide behind American corporations and their products. This is not something Americans can blame on others.
Do Whatsapp and Facebook really need to be selling political advertising space?
Do they even employ people who can read Hausa, Yoruba or Ibo? or any of the other 25 or so languages used in Nigeria?
America may be ok with "The Right to lie your head off" but it is hard to argue they have the right to force this on others who do not have a similar culture.
I personally had a Nigerian woman say to me "Did you know Michelle Obama is a man? It says so here on Youtube!" - which it did, with Photoshopped pictures as evidence. The woman who said this in in her 60's. has a degree in business administration in the UK, and speaks perfect English with no obvious accent.
On looking at her Youtube "home", I could see she was being targetted with a continuous stream of propaganda against other Nigerian ethnic groups than hers while here in the UK. Yes, Youtube IS trying to incite genocide in Nigeria. Even if they are blaming it on "the algorithm", Putin or Trump - it is still shit stirring at the level of inciting murder.
A lot of what he says is actually reasonable. Nigeria probably has a similar proportion of illiterates to America, however, they are not evenly distributed among ethic groups - in some groups it is over 90% literate, while in others, probably less than 20%, and Boko Haram, are by definition, terrorist illiterates fighting for everyone else to be as illiterate as they are.
Illiterates may not lack critical thinking, but they certainly lack the tools to check on facts - in many cases, they probably do not understand the concept of checking.
There is a further problem: the concept of truth is connected with the concept of "one God" - they truth is what God sees. Nigeria has a significant proportion of people who believe in Many gods, and they do not have the concept of a constant truth that Christians and Muslims do. They are often taught the "truth" is what the oldest person present says (challenging an older person generally ends badly). If different elders report different stories, they may believe that the "truth" has changed.
I don't believe for a second that the Chinese government has the power to make the sort of structural reforms that will meaningful change the issue of intellectual property or cyber theft
The world does not revolve around you belief system.
Development is a wonderful thing. The Chinese have already decided that Intellectual Property protection is in their best interest, now they have a lot of their own Intellectual Property to protect.
At best, Trump is going to gain credit for the already-happened.
Attempts to crack down on the communist party? You do realise that, since 1970, the percentage of Chinese below the poverty line has gone from 85% to 8.5%*! There is no clamour to overthrow them, nor likely to be in the foreseeable future. However, Chinese production costs are likely to rise, and demand for imported goods will also. The Chinese know well they have more dollars than is good for them, but what is less clear is whether the Chinese people want Gangsta Rap and Hollywood movies. America does not export much else.
* By 2020, American poverty will probably go from 8.5% to 85% - especially if you don't dump Trump.
I would guess that the higher conductivity of metal means the resistance related losses are lower, and thus faster and less heat.
There is, of course, the problem of voltage breakdown if things get too small, and potentially, at very small scales (people talking about only room for one water molecule) electrons tunneling (due to quantum effects, you can't be sure if the electron is in the metal or in Schroedinger's cat).
I have writer friends who complain about keeping track of old versions of manuscripts, and I keep telling them they should use a source control system.
LibreOffice, MS Word, and most other credible writing tools have a "track changes" option which does this.
It is also possible to tell LibreOffice to store documents in a form compatible with version control but hellishly difficult to find out about the feature (also applies to most LibreOffice features).
Relevant to previous statement:
The Internet desperately needs a way to hide old tech support info when out of date, unless a "reveal" button is pressed. There is a wealth of info on how to fix ancient versions of software, making it impossible to fund the latest fix. (Yes, I know: if Google search actually searched for the search terms you entered, it might be easier.)

Strait from the Fortran manual - if you ask my mother :-}
No, actually, they weren't.
The US Government is definitely tangible. However, I agree its credibility is in serious doubt.
We have a traditional saying, here in East London: "If you can't tell if you are being scammed: you are being scammed".
You must be new here.
Must think "outside the skull". (Personally, I suspect zombies would be a good choice for the HR department. Unlikely to be worse than the current lot).

NOTHING beats an ASR33!
This is Australia, where the laws of the nation Trump the laws of mathematics.
Even in 3rd world countries, most people over the age of 11 already have two.
You have to admit it beats the hell out of a Lear Siegler ADM3A.
