The somewhat-standard definition of the naturals (0 = {}, 1 = {0}, 2 = {0, 1}, 3 = {0, 1, 2}, ...) also maps min to set intersection. GCD, which someone else mentions in another comment, is very straightforwardly a set intersection problem.

The intuition here is that an operation throws away information that isn't relevant while keeping the relevant information. If you can't lose relevant information, you can't fail to be associative. Probably all such operations can be straightforwardly mapped to set intersection or set union. (Under the definition of the naturals given above, note that set union gives you the max operator.)

> Meta point: do we have to accept deception as a necessary part of sales? It seems strange that we accept deception and manipulation as necessary ingredients in the market, and that its on the buyer when they "get duped".

I guess I would clarify what you mean by deception. One of the key parts of sales, at least when it comes to technical sales, is that an answer to a question or a presentation of capabilities needs to be made in a context. You have to know your audience. When you're talking about how your software does authentication it's absolutely appropriate to describe it as "integrating into your existing investments in authentication" when speaking to the business side of the audience. This is compared to going into detail (e.g. NTLM, Basic, SAML, Kerberos, OIDC, JWT, whatever) when speaking to the technical side of the audience. Is the generic answer to the business side deceptive? I don't see how it is. It's not their role to analyze the technical merits. They just want to know how much extra work will it require, in general, to deploy the software.

Is outright lying necessary? No. I've only been on the sales (technical sales, but nonetheless sales) side of the world for 1.5 years, but no, you don't. I am fortunate that my manager has carved out a team where the _expectation_ is that we are technical stewards of our customers. Obviously our end goal is selling software, but the immediate goal is to make the software work. It's a norm on our team that it's entirely acceptable to join a call and tell the customer that a competitor would be better suited for the use case.

While it's not necessary, it is hard. The incentives for sales aren't aligned with telling the truth. But this is where culture matters quite a bit.
AR won't get you manuals.

There will be less AR manuals since they will have to produce both paper and AR.

To recognise parts will take pretty good pattern recognition, but possible, what can a phone do now?

But the next step will take AI at a fairly high level if it's guiding you through a process.

If a camera can look at a motor and 'see' what to do, then just a voice telling you want to do will be close to brilliant and useful now, camera and speakers are easy.

True a overlay would be better, but the underline tech is AI, if you can make this AI then no need for AR at this stage, sell it now if it's possible.
Is it though?

> To me, this implies a further disadvantage: extremely high latency when compared with in-person collaboration. That can be fine for some things. But there's all sorts of work where I really value live discussion.

But even when you work in the same building you still have to find a time slot that fits for a meeting. Of course, you can also drop by the other's office and hope to find them ready for a chat, but there's no guarantee.

And for remote companies I imagine that people actually have more time slots open for (video)chats, because people don't have to allocate extra time to travel between meeting rooms.

Of course, the dynamics of a live discussion are somewhat different from a digital discussion. But I think the availability/latency issue is a misconception.

> Three years ago this month, as Snap Inc. went public, NBCUniversal announced that it had invested $500 million in the company.

Not sure why you would invest in Snap at their IPO price at $17, given that they had no prospect of profitability or any signal of growth due to Instagram's aggressive copying strategy at the time.

Compared to three years ago, $10 is a bargin, but no better than the $5 price in early 2019. Better wait for it to enter single digits.

I know it's probably old news to most of you, but Facebook's content policies are genuinely moronic. I ran a confessions page when I was a student and some of the moderation decisions were breathtakingly idiotic. They'll let racists, homophobes, anti-vaxxers (a genuine threat to public health!) and all kinds of terrible people off scot-free but an off colour joke specific to a tiny university gets the page removed and the owners are forced to build up their userbase again.

> For the sake of women and men everywhere, here’s hoping this shape won’t be ignored any longer.

What is the point of painting this as some sort of marginalization of women or greater injustice? First of all, I don't know anyone that isn't aware that the clitoris has this structure. Second of all, it impacts absolutely nothing anybody does; nobody is ignoring this structure due to a patriarchal obfuscation of anatomy.

What's this new information about the clitoris? Oh, it extends internally and has some interaction with the vagina? What an impactful new piece of information, as up until this point apparently people were not particularly concerned with stimulating the vagina...

I feel like this is the equivalent of being like "we just found out that taste buds actually continue being able to taste as food goes down your throat. It's about time we stop ignoring these taste buds." By doing what, continuing to eat food and swallow it?

Who is ignoring this inner clitoris? What is anybody supposed to do differently?

> because they are not based on an objective skills or supply-based metric

Then you have to ask why do these clusters exist - with high skills, high salaries and high costs?

In my view, that's because there is value created by proximity.

It is more productive to have people co-located in the same office.

Also if you live in a major university town, or high tech area then that accelerates the exchange of ideas, particularly outside peoples direct areas of interest. This makes for better networked, more creative employees.

Co-location of companies also increases the chances of collaborations and deals.
There's no fair. There's supply, demand and people trying to make their ends meet in between. You are just the same hired worker as everyone else, and if your bosses found a way to get your work for less money, they would gladly do it - it's just they can't. People with other professions are not paid less because of you, they are paid less because of capitalists, who get much more money than you and maintain this system. It's capitalists who should feel sorry for these people, not you.

Do you really feel "rich" as a hired employee? Eating sushi and owning a car is "rich" for you?

String theory has tons of detractors.

General and special relativity had detractors until experiments.

We could go back to copernicus, galileo and eventually to aristotlean physics.

But that's not the point. You made it sound like all experts are. I proved to you that it is not the case. Many times, it's the experts doing their damnednest to prevent progress. It's a small group of experts who fight and succeed against established expert dogma.

> They may miss the mark sometimes, maybe often, but they're also the only ones hitting the mark.

Who is they. You act like "they" are all working towards a common objective. I showed you that's not true. Many times, sadly, experts work hard to maintain the status quo.

I suggest you look up a book on philosophy or history of science. It'll be an eye-opener. It seems like you still cling to the silly "perfect" idea of experts.

This is actually due to the inclusion of suburbs and exurbs in the “urban” category for US, Canada & Australia.

That's entirely subjective and dependent on the conditions.

Testing every single person arriving from abroad wouldn't work. The test is not reliable for people still in the incubation phase, and with exponential spread being what it is there are going to be a lot of those. I don't think there's any country on the planet taking that approach; they're all either banning travel from affected countries or forcing a 14-day quarantine period on travellers from them. The American media seems to have oversold people on how powerful testing is for domestic political reasons.

Also, 4 hour turnaround testing is really hard and I don't know of anywhere other than South Korea has managed it. They basically have to process the tests on site after collecting samples to achieve that, which is no easy feat as it requires not only specialised equipment and trained staff but also a carefully set up positive pressure room to prevent sample contamination. Plus, one of the key things that makes South Korea's approach so effective is that people drive up, get a sample taken, then immediately drive home to avoid spreading the disease to anyone else rather than waiting around for results.

I haven't even seen any examples of countries with substantial travel from Europe that routinely test people who've been there recently and developed mild potential symptoms. South Korea probably could but I haven't seen any confirmation that they do; they mostly seem to be focused on contact tracing and the large local outbreak. The UK and Europe don't. Maybe China does? Again, the American media has been running stories making it sound like the fact the US isn't testing everyone with a cough and a sniffle puts them massively behind the rest of the world and confusing people about what the rest of the world is actually doing.

Two possibilities:

- the goal isn't to convey information, it's to appear to convey information so they can defend themselves later on

- we tend to hire artists who are concerned with appearance into roles that require visual engineers

The former seems to be something that the UN struggles with. For instance, they can't indicate how many people have coronavirus in Taiwan because they need to consider the feelings of their member states. And they can call one recent coronavirus "Middle East respiratory syndrome", whereas another has to be called "SARS-COV-2" to avoid racist implications of a geographic name.

The latter is a widespread problem. For instance, once upon a time, software design gave consideration to making it easy to approach and use, especially by people who might be using computers for the first time. Nowadays, it's primarily about making sure the software looks fashionable.

My trust for international organisations has gone down the loo thanks to this outbreak. I am sad.

I disagree. I haven't lived in China (for more than two months at a time), but traveled there multiple times, which was an eye-opening experience. I've met several foreigners living in China, some of them since before 2010. There is no raise in xenophobia according to those people.

The clickbait that these two Youtubers spread on their channels creates a very, very biased picture of China, and Chinese society (to the negative). Things are blown out of proportion or presented with misleading or no context. Even when they pretend to make a positive video about China, they can't help but add a few dismissive comments here and there.

All of the aforementioned people I know dislike their content, because they feel it misrepresents China as a whole.

I could go on about how and why I think these two guys are toxic, but the gist of it is that I actually used to watch their channel regularly before they became full-time youtubers, which was a turning point. Over the following 6-12 months their content slowly became more clickbaity and generally negative towards China. But I guess once you depend on youtube financially, you simply make videos that get the most clicks. Their comment section slowly turned from "sometimes filled with Chinese trolls and otherwise cool people" to a cesspool of people living in their echo chamber of "murica is awesome, teh commies are evil", and obviously still a lot of Chinese trolls.

Their content doesn't help to get insight into China. It helps you to strengthen the bubble you live in.
What I don't like about that page is the way they hide the active cases graph, and when you show it it's tiny. I would like a graph that shows the active cases as its most important figure. Total cases is interesting from an immunity standpoint, but active cases is important from a "will i catch it" standpoint.
UK is currently 29th on total cases per million population (6.7). That's pretty far down the list.
Tests indicate coronavirus can survive in the air
The analogy with the Prisoners' Dilemma is interesting here, but doesn't feel quite right. In the comments, BenWang summarizes it like: "the effects of the attacker will happen to all token holders regardless of what you decide to do with your tokens, therefore, you might as well rent them out."

It seems that the MKR holder in this case could rent them out... or sell MKR and exit their position entirely. And this seriously discounts the fact that eroding Maker security is immediately obvious and can get priced into the MKR token very quickly, defeating the point of a few percentage points of yield.

It makes sense on some conceptual level, but it's not clear that the magnitudes of the incentives result in this toxic game theoretic equilibrium.
Then apply for SRE.
