47 pixels per degree (PPD) would certainly be good enough to emulate a desktop monitor. In reality, 35 PPD is sufficient, albeit only capable of emulating low end monitors. 62 PPD is roughly the limit of human eye resolution for a general static image.

I would be surprized if this Hololens is up to 47PPD, but to my pleasant surprise MS did make a big leap (no pun intended) in optics his go-round. So, I suppose it's possible.

Transfers of personal data to non-EU countries are specifically regulated by Chapter 5 of GDPR. After Brexit, Britain is "foreign" as far as the EU is concerned.

It's also worth noting that a lot of Brexiters consider closer political ties and a strong trade deal with the US as an essential element of their ideal Brexit scenario, by weakening Britain's ties to (and dependency on) the EU. In a no deal/hard Brexit scenario, Britain may lack the negotiating leverage to assert any meaningful kind of sovereignty. Many pro-Brexit campaigners have described Britain as being trapped in vassalage to the EU, but a chaotic Brexit could make Britain just as dependent on the US, with everything that implies politically.

> I can not see how it would work if the majority of people did this.

What would fail to work, in your opinion?

A couple of observations:

First, actually productive work is probably on the order of that anyhow, most of the "8 hours at work" tends to be wasted away.

Second, a lot of our material possessions can now be provided with automation.

So there's probably not that much if any economic loss if people worked less. However, let's assume for a second that working 4 hours instead of 8 would, in fact, reduce GDP by half. In 2017, the US real GDP was $18 trillion. If we halve that, we go back to 1989. We were actually pretty well off in 1989[1].

And yes, macro-economically I also don't understand why recessions are so horrible. Let's assume they throw us back a year. So what? Things were generally pretty OK last year, and at any rate not much different from this year.

AFAICT, the reason recessions are so horrible is that they hit very asymmetrically, so some people are a lot worse off. So it comes back to distribution.

Have been there as well. My current position on this is, that the sources for success are hardly one dimensional. Sure hard work helps, but it also helps to happen to have good contacts, be born rich, be beautiful and tall, been grown up in the right social circles, having met the right people etc. So it‘s less punishing hard work, and more creating a balance with those less lucky.

Also, the science is starting to question the supplementation. It’s too early to tell, but one hypothesis is that it is a biomarker at the end of a pathway and not at the beginning of it, i.e. as a consequence of a proper diet and sunlight, and not a cause of a healthy system.

I wish I can test drive one of these in the US. Competition is always good for capitalism but I fear for Tesla and the implications for manufacturing their cars in China soon with many of these Chinese government backed EV companies. That being said, I find it interesting how there's a couple Chinese companies that are on the US stock exchange. A couple of my friends was raving about the NIO IPO a couple months back about how a Chinese government funded "Tesla" cannot fail. It's weird how it's acceptable to buy a "stock" of a company without really owning part of it, similar to Alibaba. The stocks on the exchange is just a subsidy of the company that contracts to share the profit among the holders.

> It's not clear to me why the VPN people are more trustworthy than ISPs.

In my country, the UK, ISPs are legally required to retain logs of customer activity for 12 months. A VPN has no such legal requirement.

So while I can't be 100% sure that my VPN is monitoring me, I can be 100% sure my ISP is. Additionally, my VPN has a financial incentive not to log customer data, or at the very least, not to be caught doing it.

(I'm currently using IVPN (https://www.ivpn.net/). It's on the more expensive side, though that isn't necessarily a bad thing, and it supports multihop over OpenVPN, and the experimental Wireguard protocol.)

I wonder if there are papers on how to restructure large systems. And if modular analysis can reduce the cost of deep+late refactoring.
Szasz's "The Myth of Mental Illness" is one of those works which is completely and utterly misinterpreted simply because of the title.

I don't have the book available at the moment, but in the introduction he says something to the effect of "I don't regret writing this book, but I regret calling it what I did, because people judge it without reading it."

The gut-reaction to such a title is to think the writer is saying "depression doesn't exist" or "schizophrenia doesn't exist" or "manic depressives are lying."

This isn't what he says in the book at all. Rather, his argument is more along the lines of:

1. The word "illness" should be used to represent a cause-- and resolving the cause should cure the illness. Cancer, the flu, hyperparathyroidism--all map to causes.

2. The conditions which we call mental illness don't have a knowable cause. They are symptoms which we pattern match against.

3. Corollary: Illnesses should be hypothetically curable. There may be a cure for cancer. But there cannot be a "cure" for most "mental illnesses" because there is no shared, physical cause that underlies say, all cases of "bipolar disorder".

3. So we shouldn't call them "illnesses". We should call them something else.

Unfortunately that's about as much as I remember of his argument, but it's very different than the common accusation... And it also strikes me as accurate.

The problem with naming things is that it makes them real. I think often the hacker news crowd forgets how ill-informed most of the world is, and the degree to which people crave certainty.

When a person is told by a psychiatrists "Your 8 year has depression so we'll put her on X pill" or "You have bipolar type 2, so I recommend Y medicine", it has a certain finality.

Most people don't think "The doctor is telling me that my behavior matches some patterns. That is it. She does not know why, and we may never know why, there may not even be a reason why. So we should think about what we can do to mitigate this."

No. The we think "I've been diagnosed with a disease. (Sorry I'm being an a-hole|I won't go to your party|didn't get out of bed), I suffer from bipolar and there's no cure".

I recognize math as a source of useful ideas. I want a high level overview of what math can do, so that I may draw ideas and solutions from it as needed. I find that many proofs are intuitive, although I can't prove them myself; that's OK, I am happy with my fuzzy and fallible intuition here, and it serves me well enough. This is not unlike mathmeticians who often suspect something is true before proving it.

Test cases are not proofs. I don't want to write mathematics, I want to write code and maybe draw some fuzzy and fallible human inspiration from mathematics.

I don’t see why this is that thought provoking of a prediction. We have already seen the shift from dairy based milk to almond, soy, oat milk, etc. We probably could look at milk choice in coffee in urban areas vs nationwide, etc. and get an idea of the potential percentage of the population that chooses a dairy substitute. Similarly, my guess the market adoption for dairy free cheese substitutes is quiet low. With meat, I highly doubt it would be broadly abandoned across all types of meat. For instance, maybe the impossible burger overtakes the burger, but people still like steak and there is no substitute.

It really depends on which industry you're talking about. I remember somewhere reading about "emergent" and "convergent" industries.

Many mature industries like commercial aircraft manufacturing are "convergent" meaning that their goal is providing the customer what they're expecting. Success is measured by "meeting the spec", beating the competition using some combination of price, reliability, time-to-market, and leveraging established status and reputation in the market. I think your SW development analogy of version control branches applies to convergent industries.

There are other industries which are "emergent." These types of industries attempt to create markets with entirely new and unexpected products. They don't face competition, instead their success hinges on developing the market for the product.

The rules are entirely different for each of these two categories.
It's similar to the "unit" in "unit testing": people will relate the most basic meaning to something they already understand, resulting in different, subtle distinctions.

In this case the breakdown actually seems the same to me as with the common unit testing misunderstanding - breaking down by syntactic form instead of conceptual form.
I'm gonna say, don't be too hard on yourself. You may expect to be as productive as on your previous job, but there is a big chance that you won't be. It will take some time to adjust to the new setting (even if you worked in your free time on the business).

Anyway, congrats, good luck.

A notable and reasonably thorough investigation into the state of the C++ lifetime checker as of June 2018.

What I took away from this is the impression that the work on the lifetime checker is incremental and the tool was able to deal with a certain complexity of cases, but beyond that backed off and produced either false positives or negatives.

Roughly speaking, the author found edges of the checker implementation around code "hiding" from the checker in functions (ie. missing inlining capabilities), or const& in combination with either typedefs or vector operations, temporary value lifetime extension rules, and some others.

It seemed that in general the lifetime checker was already working in terms of the fundamentals of the C++ language, but it needed more work in order to be able to "see" through all intermediary function calls and as such also be able to handle cases involving standard library types, which any user of the tool would expect to be understood perfectly.

It has complete hand tracking, so we can make much more accurate and realistic movements than with the first hololens.
