The scanners in airports are currently millimeter wave machines. They're fucking useless with insanely high false positive rates, but they don't appear to have any health risks (unlike the backscatter x-ray machines from a decade ago, which I'm sure would be facing cancer lawsuits today if they were still in use).
What do horrendous about it? Adopting the stoic approach to tempering your impulses, accepting that which is beyond your control, and seeking happiness from within doesn’t sound horrendous to me at all. There’s plenty of wisdom in Stoicism for people to benefit from.
Nearly 25% of all Smartphone were iPhone according to different Data Sets in China. That is very high considering the majority of population has Sub $10K salary.

From about 800M Smartphones, 25% equals to 200M iPhone in use. China has to be top 3 countries ( if not top 2 ) with the most iPhone in use.

And that is one reason China seems to have sided with China so far.
Why ban? In Switzerland you pay the same amount of property tax if you rent, live in or keep your property empty. The tax is adjusted every six months with the medium rent values.

Charitably, I assume that you are a troll out for giggles, rather than an actual white supremacist.
The argument for student debt not being dischargable is to stop lots of people declaring bankruptcy upon graduation.

You can repossess a house or a car, but you can't repossess a degree.

If there was an option of cancelling a degree (either because of bankruptcy or user disatisfaction) this could perhaps work for vocational degrees or where the degree is 100% signalling.

If some kind of learning took place - how do you give that up?
It's not that proprietary or SaaS (PaaS, Iaas, etc.) is bad, it is a case of thinking through what you will do when (not if!) the provider decides to shut you down.

You can get shut down for any number of reasons, and you may not know why. Google is renowned for closing accounts so you lose everything laterally where you rely on the G, Paypal is renowned for freezing money for months. A cloud provider shut us down at work for a day because we got dished up a IP that someone else had abused minutes earlier. So yeah whoever you use, eventually and problematically they will f' you over. They will give you down time (temp or permanent) and/or they'll leak your data.

So with that in mind you need mitigation. Not necessarily run your own racks full of only GNU software on open source schematic hardware using batteries & solar panels, but bear in mind what to do if the provider messes you up. For somethings you might have it tuned up beautifully where a DNS entry with a 60s TTL switches you over from AWS to Azure and it's all running nicely again, and you set up DO as your next fallback.

For other things, it might be a case of 'well we will need an engineer to port it all over, might take 1-2 hours but we know how to do it'. Whatever it is it needs planning.

Of course it's horses for courses, and most start ups would weigh up the risk of being hung to dry by their SaaS versus the much higher risk of simply not succeeding financially.

But boycotting cloud / SaaS might be a business mistake. However if you are doing it for philosophical reasons I guess that is different.
That seems like a weird reason since the radiation counter argument was typically countered by pointing out the radiation from the flight itself likely exceeded the scan by a lot.

This is likely about as safe as wifi. The paper someone linked describes a system using around 24-30 GHz microwaves, one of the company blogs says the power they transmit at those frequencies is even less than a typical router. This isn't unusual. You can see a list of over 800 FCC approved devices in that frequency range here: https://fccid.io/frequency-explorer.php?lower=24000&upper=30... (I also didn't see anything there for Liberty Defense, the company suspects they'll have a product ready by 2020 but we'll see. Radar and imaging applications are tricky, this company could implode beforehand.)
Hubski looks really cool, except this part:

Nobody is saying physical pain is the only pain worth considering. What people are saying is that if you asked 100 coal miners and 100 tech workers to swap jobs for one year, then asked them one year later whether they would like to switch back, there will be an overwhelming asymmetry towards staying a tech worker.

The problems a tech worker faces is minuscule relative to a coal miner. And the above thought experiment highlights that.
There's a photo of the third author (the cat that motivated the experiment) near the end of the paper[1]. They state that they tried it on a lot of cats, and many rejected the cameras.

Ye shall know them by their fruits: https://mobile.twitter.com/cmclymer/status/11345548023299153...

Make no mistake - LGBT rights are under direct attack by the Trump administration. We are likely to see major setbacks in the near future under the guise of “religious freedom.”

Take it from someone with a vested interest in the subject (I’m quite gay): this one isn’t over.
I'm being a bit pedantic here, but they are too, so let's consider:

They argue that wooden blades are less energy intensive to produce, which is technically true if you discount the amount of energy to grow the wood in the first place. What we're actually talking about is additional energy cost over the initial sunk costs of the wood (which don't really matter to us). This part is mostly trivia, but it ties into another point:

What are we actually worried about here? We're worried about unbalancing our ecosystem, and additional energy expenditure is assumed to not be supplied by renewable energy sources (which is generally true today). So our fundamental concern is the release of greenhouse gases (due to burning of fossil fuels in order generate energy for production).

The calculation then becomes: What is the cost in greenhouse gases of cutting down trees to produce turbines? Trees are carbon absorbents and carbon sinks, after all. What is the cost in greenhouse gases of feeding the people who expend their vital energy to produce the wooden turbines? How does that cost compare to production using robots? How does that cost compare to production using synthetic materials? Does that calculation change enough to matter as the source of energy moves more towards renewables?

What I'm getting at is: Where is the actual CO2 bottleneck in production? We should be optimizing the bottlenecks first.
AFAIK, metal detectors (the standing ones) use a simple coil and a receiver on the other side to detect changes in the EM field. The hand-help ones like these ones use either radio waves or microwaves to scan for metal, so non-ionizing radiation. In both cases metal detectors should be safe.
Millimeter-wave machines at airports today are totally and completely useless. Germany's transportation administration reported a 54% false positive rate for these pieces of rubbish. You are better off randomly searching people by flipping a coin.

These are multi-million dollar security theater failures and it bothers me more that people are considering buying even more derivatives based on this garbage technology for anything.

Police officers or security guards could just literally point one at anyone they find suspicious and use it to justify an illegal search, because it will most likely read yes, even if the person's pockets are totally empty.
The problem with training pilots for a new machine isn't the training itself but rather, that a pilot is rated for one machine type only. If the MAX had a different type rating, MAX pilots would no longer be rated for the non-MAX 737. There are some larger US carriers which are 737 only, partly so that all pilots are trained for all of the machines. Having to split the fleet into two types would have a huge impact on business. Most likely these carriers would avoid getting any MAX as long as possible.

I don't know what is the correct answer to the problem, but clearly good safety regulations are trapping some carriers and Boeing. Sooner or later Boeing will have to build a true successor to the 737 (and I guess, they now wish they had sooner)
“The primary benefit of SQL is that it’s understood by all data professionals: data scientists, data engineers, analytics engineers, data analysts, DB admins, and many business analysts.“

No, the primary benefit of using SQL is not SQL itself but the “free features” you get with the RDBMS you’re using. Enforcement of primary keys, automatic data type conversions, free transactions! and rollbacks ... and the sheer gift that is set-based operations on large chunks of data. It is just plain stupid to want to code the transformations or insertion of millions of rows iteratively than to rely the implicit rollback power of an INSERT statement.

Rule # 1 in my projects: Avoid getting sexy in code, use the RDBMS for all transformations post staging. Always stage to RDBMS “as is” (data warts and all). Cleanup with SQL and stored procedures. This way you can SQL query the whole original format and figure out the best cleanup and transformations needed.
How about tools like Grammerly? Sentence rewriting, spell & grammar check be electronic and automated.

Since Google is/was already banned in China, how did phone manufacturers circumvent that in order to use Android in the past?

Did they just sort of turn a blind eye towards it or something?
There is another reason for that. Alibaba has always wanted to be listed in HK. But system in places requires all shares has equal right, you don't get those A B C Shares in US where they have little to zero voting right. Jack Ma said the these rules are old and US way of cooperate ownership is the way going forward. Which leads to Alibaba went to US to be listed.

Now HK has relaxed its rules a little bit. So this is the major reason why Alibaba is coming back to HK.
Oh, well, if we already have the calculations (and a Wikipedia page!), they must be right.
In winter I turn up the max temperature of my water heater. This way I can soak more energy into it when it's "off-peak" (cheaper) hours for electricity.
You just have to be careful not opening the tap on the hottest temperatures anymore.

I don't see how you picture it with the fridge though. Aren't you limited by the fact that you can't go down much below 0°C ?

Or perhaps you add some new mass?
Where do you actually put this mass when the fridge is already full?

This is kind of neat, but the fascination with wood blades is like wanting something to be "organic".

The article claims getting 30,000 KWh/year from a 10KW wind turbine. That's optimistic. Burgey, one of the larger makers of 10KW wind turbines, only claims 13,800 KWh/year. There's a standardized way of measuring this, with reasonable wind speed values. Few places have an average wind speed of 15 MPH near ground level. (And you don't want to live there.) That guy on the Scottish coast mentioned in the article might get that.

Compare a commercial 10KW wind turbine.[1] Costs about the same, about US$40K, plus installation and tower. 10 year warranty. (Wind speeds above 135mph void the warranty.) "Designed for high reliability, low maintenance, and automatic operation in adverse weather conditions." Which is the real problem with wind turbines - surviving adverse conditions.

For those not familiar with it, the "caliber" system is in theory the diameter of the barrel in inches, so a .45 caliber handgun has a barrel diameter of .45 inches (except in reality it's .451 inches.) Some, like .380 ACP (actually .355 inches e.g. 9mm) are off by even more.
"Deep Learning"

This looks like totally marketing bullshit. Exactly how are they training their data sets? How does deep learning distinguish a pocket knife from keys?

I call total bullshit. I bet independent tests will show massive false positives (either that or a total failure to detect any real weapons). You're better off with a metal detector.
I don't think I've ever made a point that PL (and earlier PL-LI commonwealth) had a stellar record of treatment of minority nationalities in its borders. Could you clarify with which point I'd made you argue?

They sure do have jobs, but you can't land in a random small city and expect to find a specific pair of specialist jobs. Small cities work great for single-income families that aren't picky about which particular city they end up in. Non-specialist second income is fine too.

Example: There are lots of small cities with openings for librarians, and lots of cities with openings for CNC programmers. It is far more difficult to find a small city with both, so insisting on that sort of two-income situation in a small city isn't going to go well.

The same goes for nearly any kind of skilled employment. The jobs are there, but you can't throw a dart at a map of America and expect to find two very specific job openings in one spot.

This may be one factor driving the urban-rural political split. Single-income families are different from two-income families.
The problem isn't the certification of the plane, it is the certification of the pilot. A 757 or a true successor to the 737 would have meant that pilots would have to be certified for the new plane - and that means they lose their certification for the plain 737. The MAX is targetted at carriers which already have large fleets of 737 and the idea was that the same pilot could fly both.
It will fly only to be voted down with customers feet. I know a lot of people who looked on the plane type for the first time during their holiday bookings. This plane is finished.
Good explanation, I think this is pretty close to my understanding as well.

You need to keep in mind the first body scanners were not millimeter wave scanner. They were much more dangerous back scatter x-ray machines.
Fist let me say this thread has turned out to be possible the most important thread in regards to modern web development.

Single page Applications (SPA) and frame works that are used to develop such applications are over used which have led to a whole host of problems in the software engineering industry, I truly believe that if you are building software solutions 90% percent of the time you will be building them to solve business problems, so that should be of paramount importance not necessarily the latest shines concept and tools, especially unproven tools.

A very high percentage of the developers you will interview will be using front end frame work such as Reactjs, Anuglar, VueJs ... etc as a substitute for truly understanding the the native technologies and standards support by various user agents.

The consequences of this is usually very expensive for business while resulting in software products that are convoluted, complex and unstable; I have seen this too many times.

The JavaScript eco system at the moment is littered with these kind problems, pseudo stars developers who want to re invent the wheel (without first understanding the existing mechanics), not only is reinventing the wheel already an idea that has been frowned upon for thousands of years, in the context of software development most of the times it turns out to be a much buggier and less efficient solution.

I have encountered SPAs that have been built out to be so complicated and convoluted to say the least; in order to support server side rendering, hot module reloading, dynamic DOM refresh, Virtual DOM… etc. speaking as if these concepts are some holy gifts from the gods, and when you ask the most fundamental question what are the business values behind all of these concepts, there are no good answers.
Not gonna get into discussing the objective worth of a human life, but I'll note that the entire population cares about their kids, not so much about their freedom to carry guns. Those caring about the latter are a vocal minority (or at least a subset, I don't have the statistics at hand).
Is it really that common? FAANG have millions to billions of users/customers. Can you at least cite some examples, please?

If you're FAANG-like and have 100M users an edge case that only affects 1% of customers still affects 1M people. Something that affects 0.1% still hits 100,000. Even at 0.01% you've still infuriated a small town's worth of people.

I'd hope that the average FAANG employee is smart/aware enough to realise that even edge and corner cases represent significant problems, even if all you care about is PR. (Although worth thinking about what might happen if you're Netflix and all these people decide to cancel subscriptions.)

(Incidentally, there's one plausible and recent example I'm aware of: issues with Macbook Pro butterfly keyboards.)
Problem is that government can always buy bigger weapons.

You're kidding, right? Turning off CSS is used together with turning of CSS and images to improve the legibility of some websites.

For example, using Medium with everything on is a pain. But if you switch off JS, CSS and images, very often the whole text of an article fills in one screen, is quite clean and really fast. Using Medium in this way actually becomes a pleasure (unless the images are a apart of the article) - you can navigate the website rarely using the mouse. In any case, I'm not alone in using the web in this way - turning everything on is just a waste of time and resources.
You can check it easily yourself with an extension like disable-HTML that allows turning off these thing instantly.

Yes, but the housing problem still isn't the homeless problem. Affordable housing won't prevent or cure mental illness, housing support is just a requirement for recovery. They aren't directly related.

There's no way to fix housing sufficiently to make it affordable to someone dealing with mental illness and living on the street: that problem has to be addressed separately, and directly.
So just because riding in a car with friends is a fine tradeoff to make, gun violence must be too? How exactly is it a necessary risk? Most other civilized countries seem to do fine without it.

I feel like a shill with how often I recommend it, but Keyboard Maestro [0] seems like it would handle almost everything, from window management to all sorts of system automation.

Microwave? So if we use metal wire mesh clothing it becomes kind of useless. 27 Ghz = 1.1 cm wavelength. That would require a 55 mm mesh. Food for thought for future fashion designers.
Having a high false positive rate isn't really the end of the world for security screening though, as long as they have a low false negative rate, which I don't see many articles complaining. Even at 50% false positive rate, it's 50% time saved compared to patting down every one. Additionally, these machines highlight potential areas to search more carefully, so there's probably even more time saved there.

> Millimeter-wave machines at airports today are totally and completely useless. Germany's transportation administration reported a 54% false positive rate for these pieces of rubbish. You are better off randomly searching people by flipping a coin.

Edit: note that it seems I had a wrong understanding of the term false positive rate, ignore this comment.

Statistics doesn't work like that. The false positive rate is pretty meaningless in this context. It only determines how much useless manual work is performed after the machine flags you incorrectly.

You should look at the false negative rate in order to determine how much of a security plus they bring.

That being said, I think the whole airport theater is ridicolous. If terrorists wanted to kill people, they literally have thousands of alternative ways to achieve that.

I actually like StackOverflow model: If you downvote someone, both of you loose a karma! This helps make people judicious decision on when to use downvote, at least avoids it becoming "disagree" button. This is super important because otherwise people become afraid of expressing unpopular thoughts and the forums become echo chambers. Disagreements should be expressed by writing comments, not pressing buttons.
