>And in fact mathematics is a great place to dive in, because one very important question -- namely, whether mathematical realism is true¹ -- is really a metaphysical question, and one which can never be answered by empirical observations about the world.

The important distinction between math and metaphysics is that the substantive content of the field of mathematics does not turn on whether mathematical realism is true. Mathematics tells us something about the world by telling us what can be true about the world. We know that there are prime numbers because we know that no such world exists where prime numbers are finite. But this is just saying that a system with certain axioms have certain relationships, or necessarily exclude certain relationships (e.g. whatever axioms of arithmetic you take).

On the other hand, there is no substantive content in metaphysics (at least as far as ontology goes) if the statements do not pick out real entities.
How many non-toy non-self compilers and interpreters are written in Rust?
What I think is very interesing is how Onlinedating is percieved in different groups:

While other groups of people I know everybody is on tinder, but in my local area(germany) a friend of mine is actually ashamed to admit that he met his new date through tinder..

And well, I do not think it is something to be ashamed of, but persanally I also think, that you meet dates in real life.

> I mean most pornography and such art is produced in the US itself

Most US pornography is produced in San Fernando Valley - I don't think you can generalize porn/nude art across the US so perhaps you ought to have said "California has pretty liberal standards on pornography and art".

Janet Jackson's Nipplegate wouldn't have been a big deal in any of the European countries you mentioned, but Americans were scandalized.
My experience is actually the reverse. USA weirdly conservative about nudity - to the point that Americans often confuse nudity and pornography (as you had done in your post replying to a person talking about nonsexual nudity).
Is it forever Christmas there?
Yeah, those kind of one-off contributions was what I was meaning. You are 100% right with regards to expectations, and I don’t mean to imply that they should have. Only that it’s a bit more likely than some random projetct that nobody uses.
There are others which aren't listed there, like OVH (the largest European hosting company). The dearth of banks is real though. And sad.

I have only seen client-side certificates used twice. Once at now infamous StartSSL and second at a bank but for vendor access, not regular customers.

Its huge downside is that it's a second factor which doesn't protect against a compromised device.
Spain has 3 times the population density of the US. The US would need 900 million people to have the same density.
Maybe they were too willing to believe his depiction of small town America as a bunch of poorly educated, bigoted hicks?

That’s the part that annoys me most. You want bigoted hick towns? As of twenty years ago, I could have rattled off a half-dozen towns in Indiana that would have qualified (though the author’s pre-conceived image would have been a stretch for even these towns). I can’t believe that in twenty years they’ve all turned into liberal enclaves. But that would have taken more work and research, so pick an innocent town on the map and write your narrative about them instead? And if all places, Minnesota? Of all of small town America, I picture MN as probably most “liberal”, for lack of a better description, though I admit little data.

I dunno, in the end I’m annoyed that the reporter didn’t even do a very good job of faking it, and a small town of what are probably nice folks (“damned good folks”?) took the hit.
Perhaps the best thing about Babel is its plugin-based architecture. As of Babel 7, even its parser accepts plugins.

This not only makes it easy to keep up to the latest of ECMA's standards and extensions like JSX, Flow, TypeScript – it also makes it surprisingly easy to implement your own syntax extensions to JS (eg; https://wcjohnson.github.io/lightscript/, which I have worked on).

Curious how this project is thinking about plugins and staying up-to-date sustainably.

The number one rule in dating is “be attractive”, and I mean that in the broadest sense: be someone that other people want to be around.

It doesn’t mean you have to be devastatingly good looking (lord knows I’m not), but if you are comfortable with yourself, have a sense of humor, have compelling things to say, and can demonstrate that in your online dating profile, then you won’t have a hard time finding dates.

At least that was my experience 4+ years ago on OkCupid (where I eventually met my fiancée). Granted, I think the move towards Tinder-style swiping puts too much emphasis on looks for first impressions. I’m disappointed by the path OkC has taken since being acquired by Match.

Addendum: In light of the trend towards Tinder-style swiping, it's probably worth touching on looks and appearances. Keep in mind that this goes far beyond natural good looks (or lack thereof). Part of the whole 'confidence' thing is showing that you care about yourself. In your photos and on your dates, you should be well groomed. That means being clean cut: a nice haircut, and if you are partial to facial hair, make sure it's well maintained. Wear clothes that look good and feel comfortable. If style isn't your forte, take a trip to Nordstrom -- they have personal stylists that can help you put together a classy wardrobe. Take advantage of their holiday and anniversary sales.

Take good photos. If you have a friend who's a hobbyist photographer, bribe them with a bottle of their favorite beverage to take some quality shots. If you don't, consider hiring a professional. Selfies and poorly-lit indoor shots do not go over well. And unless you're at the beach in your photos, for heaven's sake wear a shirt.

Lastly, get some feedback. There's a pretty supportive OkCupid subreddit[1] where people will generally be willing to give you feedback on your profile and photos, but you have to be receptive and genuinely want to improve. I've seen the difference it can make, and it's really quite astonishing.

I think the point is that even a minimal amount of digging into the facts behind this story would have raised a few red flags. It obviously wasn't vetted at all.
Yet these imaginary points are a source of influential power.

That can lead to money, but doesn't have to. Wielding power is its own ability.

Look no further than HN. Power is granted by how many "imaginary points" you have. Downvote, flag, vouch, and I'm sure more - there's power wrapped up in imaginary points.

And I'm sure someone would also argue that money is also imaginary points, that everyone accepts as 'monetary power's. Of course, this is orthogonal to 'karma', 'likes', or other names of the same thing.
I have not! Reviews I read were mixed, availability seems spotty, and the cost has been a deterrent. I'm not ready to spend two years of paper/toner budget on not-quite-ready technology. I do intend to look at the next generation "big e-ink" tablets, whenever they hit the street.
I began the year comfortable with React Native and ended the year in a torrid love affair with it - took the time to understand it down to the c++ bridge, forked and modified libraries to implement features that would've taken ages natively, carefully poc'd and sold my team on a simple redux implementation, and built several animated ui components (if it isn't obvious, we're a startup; yes, native is better).

I'm not sure this counts as a "technology" per se, but I've been bitten by the rendering bug and have spent the past year rekindling my traditional artistic passion for visual realism in the context of modern computer graphics techniques and have been fortunate enough to be in a position to apply graduate school for it.

Physicists here.

He's trying to explain everything in terms of a simple blackbody in thermal equilibrium, peacefully radiating its energy away only via thermal photons. That's not the reality of the radiation from the sun or moon. Solar physics is an entire branch of physics, and such simple toy models are not even wrong.

Sun doesn't just radiate away its existing energy via thermal photons.

First, it keeps burning its fuel via a series of nuclear reactions, which by the way keeps pumping energy into the system, essentially acting like a battery (so there's no perpetual motion here).

Second, sun emits photons that are much more energetic than the thermal photons from the surface. Some of the radiation is not thermal, and comes directly from different types of nuclear reactions (which provides signatures regarding the kind of reactions happening in the sun) and various other processes.

> Everyone has at least a few areas in which they could be in the top 25% with some effort. In my case, I can draw better than most people, but I’m hardly an artist. And I’m not any funnier than the average standup comedian who never makes it big, but I’m funnier than most people. The magic is that few people can draw well and write jokes. It’s the combination of the two that makes what I do so rare. And when you add in my business background, suddenly I had a topic that few cartoonists could hope to understand without living it.
Think "potato chip bag" (the kind that's shiny on the inside). It's a thin layer of metal sandwiched between two layers of mylar. The aluminum would be prone to tearing by itself, and the mylar would let too much oxygen through, thus spoiling the potato chips.
(I think when you say "tested" you mean "benchmarked" – your comment at https://news.ycombinator.com/item?id=18746905 gave a nice link to how it is tested).
It's the radiance (brightness) of the moon (as perceived at the moon) that is an absolute limit on the incoming irradiance you can create, because of conservation of etendue.

Well yes, this is what it should say! Is this our disagreement? Because for me (and I think for most other dissenters in this thread) the whole problem we have with Munroe's argument is that he keeps coming back to the surface temperature of the moon as the limiting factor. If he was simply to say that the moon is not bright enough, then we'd probably all agree.

the fact that moon rocks ... reach some given temperature X°C ... shows that this level of irradiance is insufficient to heat up your kindling above X°C.

I think this is the real point of dispute. We agree that this is true if we are only considering pure blackbody radiation. What's not clear (at least to me) is that this equivalence is still true when you include the directly reflected light. That is, no one thinks that you can start a fire using only the thermal infrared light from a dark moon. The question is whether it's hypothetically possible with a sufficiently bright sun and sufficiently reflective moon, without raising the surface temperature. Can you point to something that makes this argument more directly?[1]

the two effects cancel out and it reaches the same equilibrium temperature as a black body

I need to learn more about this. I have trouble thinking it applies correctly here, because it's assuming the moon is a perfect gray body. I think this assumption falls apart if it's actually reflecting light, which in fact we know it is. Or am I wrong? Does a silver mirror in space actually end up at the same equilibrium temperature as a lump of coal? I guess it could. This wouldn't harm much argument (the argument just requires that the temperature not increase), but would indicate that I'm not viewing things correctly.

Summarizing, I think the point of dispute is whether the surface temperature of an object in space can always be reasonably estimated from its brightness (and vice versa). We agree that it can be if it's a perfect black body. We agree that it's mathematically true if it's a "gray body". We disagree (I think) as to whether it's appropriate to make the simplification of assuming that all stellar objects are sufficiently close to "gray bodies" for the math to hold.

[1] Here's the outline of the counterargument. Start with a blackbody moon. Estimate that with perfect optics you can heat an object to X. Now increase the reflectivity of the no-longer-black-body, noting that the surface temperature does not increase. I'd argue that when you increase the reflectivity, the moon gets brighter, and thus you can heat your object to a higher temperature. You seem to be arguing that because the surface temperature remains the same, the attainable heat stays the same, even though you can collect more reflected energy.
Kafka Connect, Athena, and a lot more SQL than I didn't know I had yet to learn. Fun stuff.
Thanks Steve! Missed those; race condition perhaps. Updated.
> This is the kind of thing Rust should be excellent at.

I would actually think this (compilers) is a thing where Rust doesn’t have that big of an advantage. Compilers are very special. They mostly deal with some kind of tree transformation. And as soon as those trees use owned nodes (E.g. in the form of Box of Rc) things are not that far from what a speedy managed language would do. Compilers are also non realtime at all. It doesn’t really matter if there’s a GC pause or not, and whether individual allocations are quick or slow. The only thing that matters is the overall throughput/performance.

Now this statement shouldn’t mean that Rust is bad at doing compilers (enough projects tell otherwise). Only that in other domains (E.g. realtime and low level code, graphics, audio, etc) it’s advantages might be even bigger.
People on vacation are much more likely to stay up late partying, not understand or follow local customs, and you can't build up a long term relationship with people who are only around for a week. It is definitely a real problem.
Well... I discovered Rust and Golang and I found out that I understand Rust and started to learn it. Thank you.

I never had any problems with Babel's performance to be honest...

Also a quick check with google trends does seem to support that feeling.

> A 15 year old can easily grow enough weed in his bedroom to keep himself constantly high. This is Really Bad for profits.

I see this repeated a lot, but I have a very hard time believing it matters at all. It’s just as easy to grow tomatoes and the result is significantly cheaper and tastier than what you can buy in stores, yet I doubt anyone would say tomatoes are significantly less profitable because of it. Even in my own state where growing weed is legal I’ve heard of exactly one friend who grew their own, and that was a one time novelty rather than a real supply.

The reality is that the vast majority of customers prefer the convience of pre-packaged and pre-portioned weed products over the cost savings of growing. In fact, if anything the trend is towards more convenice (edibles, single dose vapes, delivery services) rather than away from it. The profit impact of those who do choose to grow will be extremely tiny.
I wonder if you're lumping auto-didacts with zealous subscribers. The auto-didacts (I think, no citation) tend as a group to be voracious life-long learners seeking unfiltered reality with diversity and discipline. Many have made -substantial- contributions in -most- fields.

As opposed to those who seize on one subject and are open to any 'evidence' that 'supports' it. Say, Bigfoot.

Also Docker, which I'm still not sure how I feel about. Docker somehow feels like an admission of failure of our industry to manage, install, and isolate dependencies, so we create pseudomachines to work around the problem. Better than VMs, I guess.

Nope, it's not the opposite case, I was just to lazy to spell it out. Which way around it is depends on whether it's a return value or parameter. Covariant vs contravariant. If it's a parameter an API change from T to Option[T] shouldn't break (you require less), whereas with a return type it's from Option[T] to T (you promise more).

Did a lot of learning in 2018.

Finally moved away from Wordpress as a back-end, which I pushed to the limit.

Learned Laravel and greatly improved my skills in vanilla PHP.

Moved from jQuery to Vue.js - it's now my default front-end framework.

Started using CLI and Git regularly.

Learned PWA, service workers, serverless, Web3, some Solidity, more MySQL, server admin, scaling.

Throughout 2018 I was coding all the time on my own, executing my personal projects. It was a great learning experience, and now I finally became a good and productive coder.

This is an achievement, because my first speciality is graphic design and I specialized in it for many years. Now I'm also a competent coder. When I combine design with code, possibilities are endless.
So I have several family members who work in under privileged schools, and what they pretty unequivocally say to this argument is that it's one of those "it's expensive to be poor" kind of things.

These kid's parents work two or three jobs, so we give them subsidized after school programs. Their housholds are food insecure, so we give them breakfast and lunch so they can focus on schooling and not their empty stomachs.

So much of this spending is just to try and bring these students closer to parity in the moment, but despite all of that, they don't get any that before they enter school in kindergarten, so they're sort of perpetually behind. It has next to nothing to do with government waste, or throwing good money after bad despite what that terrible "Waiting for Superman" movie told all the white flight parents looking for validation.

So you don't mind wading through some 'rape porn' while you try to find the next bus time? Because there's nary any real definition of 'art'.

Your position is nice, but it's academic.

We could even disagree on the academic points, but it would be futile: topless women and men with their dongle's hanging out are not going to be in Google Play, just like you won't see them on street signs or in shopping malls in the US, Germany, or most other places frankly.

I don't buy any of the historical (i.e. religious) or national (i.e. USA) arguments: in the UK and Sweden, they are banning scantily clad women in ads on the basis of 'sexism' for god's sake. And even if they weren't, you're not going to find men with their dongle's in your Taxi ad anytime soon either - anywhere on earth basically.

In reality, there will always have to be a line drawn somewhere.

Tumblr became a porn haven, and for whatever reason, they didn't want that, so they moved it.

Go back earlier and local government actually had ability to achieve things. Things that suited the locality.
