Flying cars or taxis will (IMHO) never take off for various reasons:

- they are inherently fuel inefficient compared to devices with wheels

- they are noisy, a problem which can probably never be solved unless breakthroughs are made in science-fiction fields like anti-gravity

- airspace is very limited. In my country, we have already serious planning problems with the current amount of air traffic

- it's not sustainable from nature-perspective. Current air traffic accounts for quite some insect & bird loss. Imagine a multitude of current airtraffic; it would be disastrous for the already dwindling quantity of airborne creatures

- flying is inherently weather-bound. Especially for relatively small aircrafts this is true. Taxis fit this property. This means service is limited to a subset of all weather conditions; YMMV depending on the area of flight.

- flying is heavily regulated, which poses barriers. Obviously, startups can overcome these barriers, but they don't help in solving the overall problem

- social opposition will always be a thing unless 100% security is neared and near-100% noiseness is reached. Until that time, there will be fierce opposition to add any type of aircraft for mass-use to the airspace

This being said, I really, really, really do like the idea of hopping in an airborne transportation device and go straight to any place in a +-(a few hundreds of KM) range.
>Airplanes rely on redundancy, which makes manuacturing more expensive but. Cars on the other hand try not to break in the first place, which is ensured through exhaustive testing and monitoring of the production chain.

I don't agree with this. You're missing a variable: safety factor. Cars try to minimize safety factor to save money and weight, airplanes often have more regulations to prevent this. Cars definitely break more often then airplanes. Also, keep in mind that aircraft can rely on preventative maintenance by trained professionals. Cars really can't, meaning they have to simplify their components and assembly a lot.

Absolutely true. Embarrassingly parallel problems are generally not the most interesting, because you can just throw compute power at it until it is solved. Most applications running on actual supercomputers are communication bound.
And presumably, the benefits you receive from a predictable morning routine probably have a lasting impact on how the rest of your day goes and far outweighs a miniscule increase in your risk of cancer. With that said, you could think of replacing the bacon with some other ingrediant except for, say, Fridays. Still very routine, maybe a bit healthier, and then a sweet, sweet reward of bacon for making it through the week.
>That is of course the only possibility Chinese can think of, while Americans just think he is being awkward.

Well, I'm not Chinese, and I think those who think he's being awkward are naive.

>Not do a bunch of cringe worthy stuff like asking Xi to name his child or jogging in Beijing smog.

Cringe-worthy to whom? Because the Chinese audience will probably eat-up that kind of soapy stuff, the same way Americans cherish the cliche stuff performed by people coming into the US and seeking their business (businesses, actors, etc).

Low average life span had a lot more to do with high infant mortality rate. It wasn't that most people were dead by 40, just that a lot more were dead by 5. If you made it through adolescence gray hair was totally within reach.

Most Irish never experience a wake. I know which island is being discussed in the piece (https://en.wikipedia.org/wiki/Achill_Island). My grandparents lived there and I attended their wakes and those of other elderly relatives in the area. But even there, wakes are becoming less and common. And wakes are generally unknown in Ireland outside of relatively isolated rural areas. I suspect in a couple of decades the custom will be gone completely.
> It'd be interesting to see what proportion of the pay gap/high status job gap comes from different sociosexual incentives

Obviously this is highly speculative but for quite some time now I have the theory that the former Sowiet Union states (Russia et al) and large parts of Latin America don't progress as much simply because male financial success isn't tied as much to better dating options. At least to me as a traveler it seems that many men in those countries have a wide choice of attractive girls, regardless of how well they are off.

This would also explain the rise of the Chinese economy in the recent decades, as they have a surplus of men and I heard that they need to own at least a flat and a car to have chances on the dating market.

Interesting. I guess this memory is also used at somewhat unpredictable times in the usual case where symbols are resolved lazily though the PLT: when you first use a function you'll suddenly get this extra stack usage while ld.so does it's thing?

Doesn't that also imply this caveat also applies to thread stacks if you end up resolving symbols off of the main thread?
I'm actually in full agreement that there are many ways to accomplish interop, with a variety of tradeoffs. It is precisely for that reason that I disagree that the statement

'One thing to understand is Evan wants Elm to be a language and not bound to JavaScript.'

is a good explanation (or a 'sound motivation') for the current design decision. Thank you for expanding on the goals of the current design. People less familiar with Elm, such as myself, have learned something about Elm's capabilities and strategies for dealing with interop.

The GDPR applies to european citizens living outside Europe.

The EU would like to think so. Whether it actually can enforce its law extra-territorially is an entirely different question, the answer to which most likely depends on the nature of any formal agreements it has with other relevant jurisdictions and/or the local law in those jurisdictions.

And to be clear, if I ever heard about a site pulling this sort of shit, I would be extremely compelled to issue GDPR requests towards it.

And that is exactly why the GDPR is too absolute and one-sided. It imposes significant burdens on those working with personal data and provides data subjects with rights that can be abused in a form of barratry.

Instead of trying to be a smartass with the law, which never works, do what every other one-man shop your size will do and ignore it until it becomes an issue.

Isn't that also being a smartass with the law?

Moreover, if compliance with the law is so onerous that small organisations can't reasonably be expected to do it anyway, that's a pretty clear case that the law is too strong.
> the linear progression of conventional warfare that existed among humans until the 20th century

In fact, one major reason for the post-WWII institutions such as the UN, EU (then called something else), and others was to prevent another war. One major reason for preventing war (there are lots of good ones!) cited by leaders was that the technology of destruction had improved to such a point that another war could devastate civilization - that was over 70 years ago.
A major problem that I see with Elm is that it seems, from the outside, to have a bus factor of 1. Looking at the commits for the compiler and other core libraries you only see one name over and over again: Evans.

Evan has created a very streamlined and pleasurable frontend experience, but IMO his tight control of it will lead to it's demise for a variety of reasons:

1. Something happens to Evan (Hopefully not)

2. Evan decides the foundations need to be replaced (For example if he moves away from the 'Elm Architecture', it will cause a great rewrite and when great rewrites happen developers evaluate other options. e.g. Angular 1 -> Angular 2.)

3. Evan gets burnt out

I'm okay with a BDFL, but not a sole maintainer. I think he needs to raise up others to maintain it for it's long-term health.

Note: Creatively I can understand his desire to control the experience. It also make it feel very unique as a programming language where you are guided in a very narrow path in development, but I believe like most creative works they get better with remixing. When the idea is allowed to be evolved, played with, broken and pushed. Yes, most of those changes will be bad but how else can we know besides trying? Those extensions of Elm's ideas are sadly currently happening outside of the Elm ecosystem because of Evans control, which I think will also lead to it's slow demise.
Playboy Drops Misguided Copyright Case Against Boing Boing
The reasoning for that is kinda thin. "I am pretty sure that practical flying cars will need to be largely self driving while flying, so they sort of fit the category." Essentially, because self driving technology is a necessary precondition for flying cars, flying cars are at least as difficult as self driving vehicles. There really isn't any argument for why flying cars aren't much more difficult than self driving vehicles.
There are 40 cases per 100,000 people in any given year. Your chance of developing colorectal cancer at any point in your life is about 4.3%, with a survival rate at five years of about 65%. An 18% increase in risk of developing colorectal cancer equates to about a 0.5% chance of dying prematurely.

Some people will survive beyond five years but die of cancer anyway; I didn't bother factoring this in, partly because I'm lazy, partly because I couldn't find relevant data and partly because the median age at diagnosis for colorectal cancer is 67.

Unless I'm misreading this, the "vulnerability" is 4 certs deployed on machines with deprecated hashing algorigthms.

The steps the author takes from that to "this could allow your machine to be compromised" are.... well tenuous at best. The idea that just because a certificate is present, an attacker will easily be able to use that to sign malware and bypass anti-malware protections as a result doesn't appear supported by the evidence presented.
This shows much the same info as Chris Urmson's TED talk in 2015.[1] Simplified for a non-technical audience, cleaner graphics, and without Urmson's clips of the vehicle encountering such things as someone in a powered wheelchair chasing a turkey with a broom. The tech video is more informative. It shows more of how sensing and planning interact. "Fences" appear in the graphics showing the keep-away area for a moving obstacle such as a bicycle.

Waymo is going at this right. They sense as much as they can, build a detailed 3D model of the world, and only use machine learning to help classify objects. Classifier failures aren't too serious; the obstacle still gets avoided, but you might not get as smooth a ride as the behavior prediction won't be as good. Compare Tesla's self-driving videos.

>I don't think any of the women targeted by undercover police officers are pursuing rape cases.

Why wouldn't you think that?

In fact, they are doing exactly that: "11 women (...) are currently suing the police after being tricked into having sexual relationships with men later revealed to be undercover officers (...)".

Especially when the "women targeted by undercover police officers" are not some hardened terrorists living undercover themselves (who'd avoid going to courts at all costs), but people e.g. belonging to some environmental activists group or some left wing protesters, etc.

At least to me as a traveler it seems that many men in those countries have a wide choice of attractive girls, regardless of how well they are off.

I am from an ex-Soviet block country (Poland). I agree that people in here are less obsessed with success and money than the Westernerns. This also translates into dating/marriage choices of women.

Obviously, this is a huge generalization, but I think it can be justified by looking at our history. Over time, so much terrible things happened here that people learned not to create too strong attachments to material things and societial hierarchies (which disappear when you're invaded by another country). It was wiser to try to find joy in family, human connection and simple things that cannot be taken away from you so easily.

The viewfinder in a mirrorless is a full-on digital display, meaning it can be overlaid with all sorts of useful information that simply isn't possible on a DSLR's optical viewfinder. You also see exactly what the sensor is actually capturing. A lot of people (me included) consider mirrorless to be the future, whereas the writing is on the wall for DSLRs. DSLRs exist because sensors and displays didn't use to be good enough, necessitating the optical path, but they are now.

Also, mirrorless is significantly smaller than DSLRs for the same sensor size. Smaller and lighter is always welcome.

Yeah, I agree. Without the monopoly, the censorship isn't hugely important (except maybe important to you as a site user, or as an interesting cultural trend).

I do think app platforms are natural monopolies, so I wonder if the best thing to do is regulate them somehow to ensure openness. E.g., require any app to be installable that does not actually do illegal things.

It's seems kind of heavy-handed, but the current situation of Apple heavily restricting the kinds of apps we can have seems very non-ideal to me, too...

(The web is a great escape hatch for all of this, as pointed out by some other commentators, but I think native is where the action is, and it'd be nice to have web-levels of freedom there, too.)

> My prediction for the post-Sovjet area was that the US and Russia would just leave each other in peace.

But they didn't. Or at least the U.S. didn't. Russia has warned for years that the US shouldn't be installing rocket shields so close to its borders. So the US has continued to antagonize Russia pretty much since the cold war was "over".

Now, Russia has started to interfere in US politics, possibly as a consequence of that, and it has also started showing its "might" in Europe.

This won't end well, if the two countries continue to antagonize each other.

> Elm would have 5-10 people in its core team, with at least a few of those tasked with triaging issues and PRs

That would be amazing, but I see this being very similar to Node in its infancy. It took a fork (io.js), and a lot of strong opinions to get Joyent to relinquish its grip on the ecosystem.

I think what the developers who forked Node into io.js showed was competency and care with regards to progress. I'm not sure that could ever happen in the elm ecosystem due to it being somewhat small and niche.
Is there seriously some new cold war going on?

Yes. Russia wants their empire back. They've already taken back a piece of Georgia, Crimea, and a piece of Ukraine.
They have vigorous triage. If you're about to die they have fully stocked ambos with paramedics providing treatment to you on the scene and then transporting you, with blue lights, to an A&E and direct into majors.

If you turn up with a broken finger you're going to have to wait for most of those 4 hours.

I "triggering" their paywall because I was checking HN. And also, "serious issues" is relative.
We've taken a very similar approach when migrating data from one DB to another (MySql to Redis in our case, but the principle should apply to any databases). We split it into 4 phases:

* Off - Data written only to MySql (starting state)

* Secondary - Data written to both MySql and Redis, and MySql shall be the source of truth.

* Primary - Data written to both MySql and Redis, and Redis shall be the source of truth.

* Exclusive - Data written exclusively to Redis.

As mentioned in the article, the Secondary phase allowed some time for the new database to be populated. And the distinction between Primary and Secondary phases gave us a rollback option if something went wrong.

> Google's promotion committee isn't an executive panel, or subject to appeals except from perhaps the highest executives. It's a random panel of experts

At most of the companies I've worked, if a VP or senior exec likes you they make it known to the committee or a key person on it.

This just comes from my personal experience working at large companies. It's also true of just getting something done: usually the most efficient way is contacting a VP (or relevant executive) who can move things. I've wasted years of my life trying to wade through bureaucracy.

> Remember we're talking about promoting an engineer to a higher level engineer, not into management.

You don't need to be in management for your people skills to matter. If you're a senior engineer / team lead / whatever, you're seen as authority, an expert, someone consulted for wisdom. If you're hostile or rude it reflects badly on the company, hence these committees look at your people skills.

> it seems at least possible that soft skills are not considered.

I can't speak for Google explicitly but I can say your soft skills are always considered. Always. They consider them when they hire you and most places absolutely place a premium on them when promoting.

It's one of the reasons the requirements for promotions are so ill-defined everywhere. It's not just a concrete list of achievements, it's how your coworkers and manager view your personality.

> but ended up being pathologically and myopically

Yep -- politics. That's unfortunately how it works. You can assume it was an aberrant anomaly, in my experience politics rules the roost when promotions are being doled out.

> The senior executive's ear OP needed wasn't one on the promo committee

The senior executive wouldn't be on the committee, he or she would put in a good word for you.

Look, you don't have to take my word for it. If you know any senior HR people at your company or other companies, ask them how promotions are handled. It won't be uniform but I'm guessing politics, reputation and soft skills are most of the time (unfortunately) going to outweigh programming metrics.
