Show HN: Signaller – the first public WebRTC signalling service using WebSockets
Hello HN!

I love decentralisation for variety of reasons and have been recently playing with WebRTC. Whilst experimenting with it using simple-peer[0], I found signalling absurdly hard! There are public STUN servers[1] (of Google and Twilio) but there wasn't a single public signalling service available... until I created one!

I wrote signaller, a WebSocket relay in Go, from scratch because all of the solutions I found was unnecessarily complex (such using socket.io) whilst plain WebSockets will do the trick.

I believe one of the greatest advantages of decentralised applications is them not being a maintenance burden on the shoulders of their developers, in other words, the absence of a need to maintain an infrastructure to keep the app running (except maybe a web server for static files). Up until now, signalling was a barrier to use WebRTC, so by making signaller available as a public service I hope to enable more developers adopt and experiment with WebRTC.

Feel free to use, but please don't abuse it. =)

Ironically, the US is one of the worst countries for extraterritorial application of laws, but I guess it's convenient to ignore for the sake of argument. See e.g. Foreign Account Tax Compliance Act (FATCA).
This was more than one in a portfolio of investments that didn't work out. He was feted on TED and other venues and hailed as a greentech prophet for making grand pronouncements about how ethanol from wood chips was going to crush oil on a very short timeline. In addition to all the investor money, he secured substantial federal and state money for his projects. But his technology could not do what he promised, see the article talk about misleading statements about yield he talked about publicly vs what was actually happening. And to this day no non-corn ethanol company in the US has been able to be economic even with huge incentives.

I've often heard of BUDS Navy Seal training that its not IF you break a bone or get hurt its WHEN. I agree it takes a certain personality.
From my reading it seems to be his objection to her method and whether "joy" is the right metric/method for determining if something stays.

While I know, from experience, what he says is true I still think that Kondo has a better system for most people. I'll do my best to explain what I've gotten from the show.

I think Kondo's approach is actually very simple and focused on a single thing: Keep your home tidy. Her job in a sense is convince people with a problem to take steps to solve that problem which often involves getting rid of things, but not always. It's actually building habits to keep things organized and realizing when something is no longer important and therefore doesn't justify the work needed to keep it in it's proper place.

She starts with clothing, which often is plentiful and easily to identify some vague person definition of "joy." Pure utilitarianism isn't right for everyone and this allows the person to determine that on their own. You can see this in the show as people go through their clothes it's hard at first but it provides a bunch of opportunities to find obvious "yes"/"no"s to the joy question. The genius I find is that she starts with clothing and leaves sentimental items for the end after you've gained experience determining what "joy" really means to you. As well as the act of "thanking" items which once practiced you can do at the harder steps more naturally and not feel guilty about getting rid of things which are meaningful, but not needed anymore.

Touching the items provides some safety by saving things which you might actually get rid of, but just can't. It makes the process much less risky. Later on, by continuing to use the method occasionally, you might realize that this actually doesn't bring you joy anymore, but now you're able to accept this and remove the item.

We're trying to be happy here, not perfect. The genius of the method is how many points of it are designed to gradually gain experience to keeping things tidy while minimizing the overwhelming feelings and riskiness that one can feel when getting rid of things. Which makes for a system that even those with the least willpower and discipline can gain something from.

It's a fact that he chose the style on purpose because the diplomatic/nice approach failed horribly at least once.
it’s closer to how beer has changed. american mass produced and majority revenue generating cheese is low quality and people have better access to higher quality cheese. so they aren’t buying the traditional money making cheeses as much anymore. of the cheese people are buying now, most of it is american, some of it imported. similar to rise of craft brew. much of the dairy supply chain has been subsidized, previously to ensure availability and lower prices. the same outcome is happening, big cheese makers in the u. s. are branching product lines to have more specialty cheeses or will buy out those small cheese makers. tastes definitely have shifted

Seconded, but I had the same problem with Elixir and Plug/Phoenix. It looks like the communities of new languages with macros need some time to mature and settle on some kind of style guide for when and how to use them. In all the Lisps I know - Clojure, Common Lisp, Emacs Lisp, Scheme, Racket - the use of (new) macros is discouraged for the most part (at least on the surface, I'm not counting using `loop` in CL or `for` in Racket). It will get much better with time, I think, but I guess there is some truth to people saying that including macros in the language can be "dangerous" :)
The linker recognizes a variable that expands to the location of the binary so you can use relative paths.

Yes, he's the dick who blocked access to a much beloved public beach. I honestly feel that we should not be giving him a platform. As techies, if we start boycotting this cunt, then maybe he'll learn a lesson that bad behavior has consequences.

But, sadly, in our community, $$$ rules. He has the $$$. So he'll get the platform, regardless of how much of an asshole he is. No different than Trump, really.
Yeah, the situation in .NET is much healthier as far as I've seen!
Chinese American here that has foundation in Cantonese as well that took Mandarin during my younger years. If you know Cantonese, I highly recommend practicing the phonetics instead of words for a bit (like during a car ride or something). When I first learned Mandarin, we were drilled BoPoMoFo since it is a phonetic based system even when they taught primarily PinYin. It helps a lot with word enunciation in the future.

"That is only true when the other language is one that someone else you want to talk to speaks AND the other person doesn't speak your language"

Don't agree. It's good for self development even if you'll never use it very often.

Language is an extremely powerful human concept. It forms cultures. They say Germans are candid and direct? Well, maybe that's because there's usually only one way to say something in German! In English, you can almost always say something that has two meanings, at the very same time.

Learning a language is like visiting a completely foreign culture and it can change your view of things. It's like having an extra limb.

Life is very long, there's plenty of time to learn all sorts of things. A second language is useful, which is why there are all sorts of options in grade school.

And Chinese is a pretty good option.
I made a web page for myself (and family/friends) where we "open source" our ideas, and which allows users to "vote up" ideas and contribute to them etc. Feel free to have a look at https://www.innoventory.com !

As the proverb goes; now you have two problems.

Depending on proprietary stuff which changes all the time, or even complex FOSS software with single point of failure developers (I dunno, TeXmacs or something) is a huge risk which went away when I bought a cheap Leslie Lamport book on LaTeX. Doesn't really matter if a new feature in proprietary application-X allows me to also use it with LaTeX. I can just use LaTeX!

I wrote my dissertation in 2004, can still trivially use the LaTeX in it, and I sometimes do. Libreoffice, Word ... pretty sure I'd have a harder time of it. Heck Libreoffice was probably called StarOffice back then!
Yes, it takes much more effort to write in LaTeX than in a "normal" word processor.

Though, for managing complex things (e.g. citations, equations, being able to change formatting of everything in a consistent way), a typical word processor is not enough.

And when it comes to typesetting, people - show me something even close to the level of LaTeX beauty. I bet that with LaTeX default(ish) settings I can create a book with better typesetting than 90% found in a bookstore.

Disclaimer: wrote quite a few dozen things in LaTeX, my PhD thesis included. For casual writing and blog posting I use Markdown or Google Docs. But for a book, I would go for LaTeX (or at least - convert to it at some point).
I really think the path forward for a majority of people is plug-in hybrids. Most people have daily commutes under 50mi round trip. For those people, a car with 50-80mi electric range, then a reduced fuel range is perfect. My spouse drives a Chevy Volt (a sadly now discontinued model), which works well for her 40mi daily commute. Most weeks, the car never fires up the ICE, and we've put probably less than 4 gallons in the last two months. However, we're still able to make long-distance trips with the 7-8 gallon gas tank that gets us around 300 miles with the ~40MPG efficiency of the ICE.

That completely eliminates range anxiety, since once the EV range has run out, you still have a perfectly normal car, and can refuel at any station. And with the spare factory EVSE in the trunk, I can generally recharge at my destination when staying overnight.
RSS was one of the few other 'killer apps' of the net after Email but for so many weird circumstances and reasons suffered a demise
@klibertp I disagree with you. Everyone here is a grown up and "hate speech" cannot be directed against an algorithmic abstraction or a way to organize code. Criticism is a valid form of opinion, including criticism on informal elites in online communities, especially within opinions which by definition are subjective.

If you feel my metaphor is hurting that's because you feel targeted there in some way, but here everyone is adult enough to build their own opinions and look by themselves there. If my comment made it to the top it is because it was upvoted in spite of having the way of use the language I have and the way my opinions are. That wasn’t the first comment when I wrote it.

I hope you realize what you are doing censoring people's opinions based on your subjective judgement of everyone else’s possible reactions, discarding people’s own judgement.

Saying that a community could die because of a negative opinion online is senseless, precisely because truly injust opinions positively reinforce groups by creating a feeling of resistance and victim identification. But my opinion was honest and metaphors are just a way of using language.

Anyway, I respect mostly all opinions but censorship. And in regard on whether somethign is hate speech or not... really, criticize an abstraction, not even an object, who could take that sentence in a literal way and interpret it by the word? You are drowning in a glass of water (yes, that's another metaphor, just in case).
Own a piece of the NYC skyline – The iconic Chrysler Building goes on the market
I do. There's actually a very plausible theory that Chinese economic development is harmed by the sheer number of hours schoolchildren spend memorizing characters rather than conceptual learning -- that moving to a phonetic alphabet would be a huge boost in terms of overall learning. (This isn't a Western argument, it's a Chinese argument for phoneticization which is still mostly opposed by the population.)

Young students don't have "tons of free time" -- their school time is spent on something, and if they're memorizing Chinese characters, then there are necessarily other skills that will be less developed.

Yup. I've always found it so bizarre that NIMBYs feel entitled to a neighborhood that remains exactly as it was when they bought their home. Is it reasonable to expect a 10 year old car to operate the same as the day you bought it?

It's especially absurd since we're talking about a global, dynamic city, not some small rural town. Can you imagine if 1900s NYC had the NIMBY culture of present day SF? It would've severely choked its growth.

SF's saving grace is its VC ecosystem and network effect between existing talent. You can barely even say they have a monopoly on talent pool, since the ivy leagues and many other top schools are nowhere near SF. These factors are gradually growing in other cities, and the bay area will get to a point where the cost of living will turn it into just another city. They've essentially created one of the worlds largest funnels of money into landlords pockets. So much wasted capital.

This isn't like the finance stronghold in NY or entertainment in LA, tech companies are involved in every industry, and don't need to be in SF to thrive.

Nashville, TN has electric buses with a fancy inductive charge port on top, allowing them to be fully charged in 5-10 minutes (they do it on a regular extended stop). An arm descends above the bus until the charging port is in place.

I am certain that could be dangerous at car height, but I am also certain some form of this will eventually replace the 220 or 440 line currently in use in most charging stations. I think battery swapping is a good idea, too but it isn't the only solution.
Maybe but the article states "Record dairy production in the U.S. has produced a record surplus of cheese causing prices to drop"

So, perhaps there is some of what you say, but it looks like the article is saying it's predominantly due to overproduction. So tastes are changing, and people are shifting their habits but milk (and thus cheese) production have continued to climb.

I just read the article, and I didn't see any mention of human trafficking. The Hong Kong opera school is described as indentured servitude.

And I'm sure a lot of that goes on there as well, but it's hard to track for obvious reasons.

I think that summarizes the constant emotional undertones in this article. This article strikes me as a deliberate re-spinning of a story meant to be triumphal, making it the sneakiest hit piece, ever, disguised as a think piece. I would think better of it, were it not for its reliance on such common knowledge preconceptions about "what the Chinese are like."

(Also the French and the British. But that is just what upper-crusty people are like. Human beings are highly hierarchical, and this expresses itself in even the most hardline Marxist states. Even some of the west coast philosopher kings and queens who hang out in places like Big Sur can look down their noses at people with almost no information to prompt it.)

"Dindim" is a slang for money in Brazil, but in a very cute way. "Money" is "dinheiro" in Portuguese so Dindim is like saying the first part of the word twice.
In terms of martial arts action those movies are pale shadows of his earlier Hong Kong work.

Partially because Chan is older in those movies and is a little less physically capable.

But IMO mostly because of Hollywood's unfortunate style of directing fights and martial arts battles.

Traditional Hong Kong martial arts movies use a lot of wide and long, unbroken shots. You can really see the performers performing these physical acts of skill and beauty -- you see their entire bodies, it's almost like watching performers on a stage. Which is of course Chan's background.

In contrast, Western directors typically use a lot of fast, tight, jerky, almost seizure-inducing cuts. A closeup of a fist hitting a face. A closeup of an elbow hitting a knee. A closeup of a face showing somebody's reaction to the pain. Etc. etc etc. There's much less continuity. 98% of the scenes are probably shot by stunt/body doubles. It doesn't take a lot of talent for an actor to pull off a scene like that, at least not compared to the traditional HK style where the actors have had a lifetime of martial arts training.

Of course, those are vast generalizations. You can name plenty of counterexamples from both schools!
Seems there's a Quora question with some answers on this: https://www.quora.com/In-the-US-is-there-a-legal-definition-...
To forgive the tautology, intelligent creatures are intelligent. Which also means that love is possible. I mean... every person who's ever had a pet (of any sort) understands this (as I stare at the photo of my recently-deceased and very-charismatic cat). It may not fit into any naturalistic model that clearly separates humans from these other intelligent creatures (and ascribes all perception of humanlike feeling to "anthropomorphism"), but nevertheless, that is how I believe it is. They play, they feel pain, they get bored, they get hungry, they get (ahem) horny, they get excited/happy, they love (perhaps dimmer versions than the ones we're familiar with, but anyway). Sometimes my cat would make sounds in the dark of night that sounded like... ennui.

If anything actually separates us from the animals, it's not these things- it's things like music appreciation or creativity. All the other experiential things we're familiar with seem to be shared with them.

(And yet... I continue to eat bacon. sigh. I've met pigs that were clearly happy to see a friendly face of any species... haunts me, actually.)
This is now a cultural battle over free speech more than a legal battle. Regulation and freedom and generally in opposition. Attempting to regulate to get free speech will just open another opportunity for control.

Laws tend to follow culture. If you start regulating speech, the shift in culture will inevitable write laws in favor of the censorship viewpoints of concern now.

The rent/price ratio is reasonably attractive if you bet on houses appreciating and taxes staying the same.
This is like the EU butter mountains of the 90s.

Except I found no mention of subsidies. Is that not a (the) factor?
Yeah, I'm not sure why the PH-1 didn't take off. 128 GB storage, Snapdragon 835, and ceramic backing is amazing for less than $300 after tax. The only "downside" is the non-OLED screen, weird reception for T-mobile, and subpar camera app (which the pixel 3 port fixes). The screen is still great and vibrant though.
Another team at my company developed a microservice that uses gRPC that my team depends on and it’s been an absolute nightmare. Protobufs are just too limited in what they can do to make them useful except in very specific, narrow cases.
That's only true when you already speak English, or at least another Germanic or Romance language. Otherwise, all this applies to English exactly the same as it does to Chinese.
Is that a new thing? I didn’t see that option when we looked and I seem to recall it was a common complaint at that time too. I wonder if that’s come about because of GDPR?

Anyhow, it’s handy to know it is there so thank you.

And statistically speaking, the poor are overwhelmingly very obese, whereas the wealthy are fit/thin. Fitness is a new class indicator.

Over 80% of Americans are obese or overweight, largely due to lifestyle choice, food addiction, and food abuse. Obesity and related disease are by far the leading cause of death and illness in the USA, it's an extraordinarily costly epidemic that nobody wants to acknowledge.
> The cost would be paid by Chan regardless of whether he became rich and famous

I'm not sure. Maybe he wouldn't have had to be sold as an indentured servant, get beaten, be deprived of an education, and sleep on a mattress soiled with piss. Or maybe he would have died of starvation, who knows? Or maybe he would have moved with his parents to Australia, where the article mentions they went. It's definitely worth thinking about.

Please don't conflate my opinion and that of the author. I can't answer what the author's point was.

> What does the author suggest Jackie Chan do instead of rising above his past? Obsess about it and wallow in despair, hopelessness, and depression?

Again, I can't answer for the author, but I can think of a few things Chan could do: help prevent a similar hard childhood for current kids. Speak out. Join an advocacy group. Maybe raise awareness of how dire the situation for many families was in colonial Hong Kong. Not saying all of these would be helpful (and maybe he already does some of this), but arguing there's only despair and hopelessness seems disingenuous to me.
Ah. Check out Polar. Same thing only better
