Basing this on personal hunch instead of any theoretical hard standing whatsoever I think black holes are really just the event horizon, there's nothing 'inside' the event horizon.

I believe that the collapse into a 'black hole' 'stops' at the moment that space-time curvature creates a sphere of space-time that geometrically appears to us 'outsiders' as the surface of a sphere or a shell - ergo the event horizon.

That is, I believe that there is _nothing_ inside the event horizon (literally nothing, no space-time, no anything), the event horizon is just the region of space-time occupying the surface of a shell inside which there is NOTHING.

I don't believe you fall 'through' the event horizon, I think that the matter that would otherwise make up the singularity at the centre of the black hole is smeared over this surface/event-horizon region.

There are problems with this idea, but those are somewhat related to the fact we believe matter becomes infinitely dense (why wouldn't material on the surface of the sphere collapse to smaller spheres/event-horizons of their own) But infinite density is clearly not a 'proven' theory, however widely it's postulated - so we clearly don't understand if that is even a physical possibility.

I've not seen anything concrete that says you can't model a black-hole as a shell of mass. As I understand it, to an outside observer a shell behaves gravitationally identically to a point mass at the centre of such a shell would.

Of course, I'm no doubt very wrong, but whenever I've mentioned this to anyone, no one has really come up with anything to say it absolutely isn't possible, not without holding on to other things we 'think' we know like matter 'should' continue to collapse to infinite density once past some arbitrary point. Something I'm not convinced is true.
"I'm still yet to be convinced that JSX is a good idea, why break existing tooling and significantly complicate parsers for what appears to only be a minor convenience at the surface level?"

Because the template is already so coupled with the view logic that you might as well put them in the same place.

And when we've reached that point, it make sense to make the template as legible as possible. Hence JSX.

Also, no one is forcing you to have the JSX and views in the same file. You could have them be separate, with a different file prefix (.jsx) for the template and not break any existing tooling.

And lastly, https://github.com/insin/msx (Mithril + JSX) is also a thing.

Ie when you put in a word 'Mroscow' it sees that this term has 500 results while a similar term 'Moscow' has 100 million results. Therefore it assumes that you simply misspelled the word and offers the alternative as suggestion.

It does not know what the actual underlying word means.

Eh. Is that really the case? Isn't HTTP2 like 95% SPDY? It's like Daala becoming IETF's NETVC and then saying the Daala attempt failed.

Also, QUIC as far as I know is still in R&D mode and I think it's meant to be more complementary to HTTP2 no? So I don't know about it "failing" yet.

I don't know for sure but personally I have gotten so few relevant ads over the last few years that I start to question all those bright engineers at Google Adwords/Adsense.

This time it is dating sites. I mean: a company that has access to most of my search history since, IDK, 2005 and still serves me ads for Russian, Ukrainian, Thai, Chinese and whatnot dating. This being despite the fact that I never clicked one single of them, the fact that I explicitely clicked on the feedback button and told them I was not interested and the fact that I volunteered to tell them what my interests really are.

Before that it was one weird trick. Before that it was "Is your PC slow". Why o why are all ads either not targeted or targeted at everyone but me?
Mithril appears harder to read than equivalent JSX.

const links = ctrl.pages().map(page => <a href={page.url}>{page.title}</a>);

return <div>
{links}
<button onClick={ctrl.rotate}>
Rotate Links
</button>
</div>;

Compared to

m("div", [
ctrl.pages().map(function(page) {
return m("a", {href: page.url}, page.title);
}),
m("button", {onclick: ctrl.rotate}, "Rotate links")
]);

I can see what the UI will be with JSX at a glance with Mithril I have to parse the code.

Dear all publishers,

Stop using shitty third-party injection scripts to deliver advertising. Find another way.

Dear advertisers,

Please start trusting publishers to accurately report page views to you, like you used to for print media. There are laws to prevent them from lying to you.

If those two happen, and ads are unobtrusive (ideally, static content), I'll disable my adblocker for your site. Until then, sorry, you don't get to force me to put up with your crap. By all means detect my ad-blocker and hold back all your content, that's totally acceptable by me.

Building up isn't affected by a land value tax, since the tax value is on the unimproved land. If anything it encourages building up.

One negative outcome, in the absence of a land value tax, is empty lots. Leaving a lot derelict may be the wisest option for those that don't hate money, as it can be held as an investment and quickly sold after it appreciates in value. No building to demolish, or tenants to evict. Of course in the meantime it's just a placeholder in the middle of a bustling city that's looking for new houses and/or commercial property.

With the land value tax they'd need to pay more to keep it empty as the area became more desirable, encouraging them to use it for some purpose or sell it to someone who intends to use it.
That's precisely the bit that is at issue. The boundary of a black hole seems to be asymmetric regarding information and the arrow of time. Not reversible, which would be a new thing.

> publishers saying that there’s an implicit agreement that they’ll give you lots of content for free

Except that it's not free, the costs are obfuscated. There are people/entities earning revenues as a result of the ads/trackers/miners running on pages, and the money for these revenues surely is not created out of thin air, it comes from somewhere.

If people were able to completely assess the (currently obfuscated) cost to them, they could make an informed decision about whether they rather skip the middle persons and pay themselves directly the content providers.

> asking users to pay if they don’t want to see ads

I am very skeptical of any claim that paywall = no ads/trackers/miners. Ad brokers will always push for their ads to be shown -- that's their job, and content providers will always be open to increase their sources of revenue regardless of whether they have a paywall or not.

Edit: of course there are also the less obfuscated costs, like extra bandwidth, shorter battery-life, and other such inconveniences.

I actually do this as well. Blank <body> tags from Angular et al get the same treatment, too. If some site doesn't want to send an an actual readable document, then there's no reason to waste any time reading it.

Unfortunately, I fear this is not a long-term solution as it lacks critical mass to effect any meaningful change. Too many sites already try various technical workarounds for ads and tracking purposes.
With proper indenting and similar formatting:

React:

const links = ctrl.pages().map(page => <a href={page.url}>{page.title}</a>);

return <div> {links} <button onClick={ctrl.rotate}> Rotate Links </button> </div>;

Mithril:

const links = ctrl.pages().map(page => m("a", {href: page.url}, page.title));

return m("div", [links, m("button", {onclick: ctrl.rotate}, "Rotate links")]);

There are JSX equivalents for Mithril too (for both Babel and standalone JSX).

Mithril templates look also very good in CoffeeScript and similar languages.
This is the flaw behind targeted advertising. Unless all advertising is targeted, the fact that some of it is, isn't much of a consolation.

Even the targeted advertising we do have is pretty piss-poor, as we all know with the classic example of buying a fridge, then getting adverts for fridges for the rest of your life.
It's a very short article describing this preliminary finding:

"...people with lower fat-adjusted leptin levels, such as high-performance marathon runners, could potentially be more susceptible to the rewarding effects of running and thus possibly more inclined to exercise."

That's basically it. Some folks get more of a 'high' from exercise than others. Big news, right? While I love the research, the way that page redirects and all the ads it's serving up (21 just now) are complete bullshit, and the information in the 'article' is not at all worth bothering with it in my opinion.

In contrast to some other languages, it's not common in JVM community to use native (platform dependent libraries written in c, c++, assenbly, etc.) libraries. I only saw examples of it for code that tightly integrates with the host hardware (e.g. directly uses drivers of some uncommon hardware devices) or other similar scenarios, where you generally don't have other choice but use native libraries.

I think main reasons for this are platform independence and ease of building/packaging/deployment. Also JDK (standard library) and library ecosystem are strong enough to provide pure jvm-based library implementations for most of the scenarios. JVM performance is also pretty good, so there is no necessity to write/use native libraries just to make application more performant.

Something I'm not convinced is true.

Sure, you can model the external gravitational field as a shell of mass (interior to the event horizon), but they you have to explain why the mass is in a shell, rather than collapsing in on itself. If black holes form as the remnant of the cores of massive stars, then there's no shell configuration to start out with, so now you also have to explain why a shell forms in addition to it is maintained. So, while the shell model may be consistent with the external gravitational field, it seems to be constructed in an ad hoc fashion.

Also, not everyone thinks matter should collapse to infinite density, e.g., [0]. I don't have enough domain knowledge to say how reasonable that particular model is. But "collapsing to infinite density" is a simple explanation for non-experts, but I don't think physicists are comfortable with it as an actual interpretation. The more common interpretation is that the laws of physics we have do not apply in such situations, and we need an understanding of quantum gravity to say what happens at the center of a black hole.

That’s stealing. It’s no different than ripping music. It’s no different than pirating movies

What a ridiculous and disturbing analogy. I'd say it's no different than looking away from things I don't want to see or closing my eyes, or covering my ears, and an adblocker is simply technology to assist me in doing so. Do advertisers really think they have the rights to force people to consume content? One question I'd really like to ask him is if he carefully views and absorbs the content of every single ad he encounters, because it would be terribly hypocritical of him not to!

Likely since they will still be high end phones, but as a trend this would suppress the price for used phones and just pushes the problem down the chain.

I tend to think dolphins communicating might have a huge technical advantage: Water transports waves way more exact and farer. Also the ability of echolocation points to a far better usable bandwidth. Humans read, speak and listen at a few bytes per second. What if dolphins send/receive information magnitudes faster?

Just imagine you could clearly hear everyone speaking within a radius of let's say one mile, regardless of walls or other sound absorbers. We would be forced to compress sentences into tiny time slices to avoid overlaps and distortion.

Pretty much a little solar energy and a crucible and you'd turn out aluminum like mad. Absolutely the right choice for a lunar civilization, instead of lifting structures from Earth's gravity well.
