No, respectfully, not unless you radically redefine what you mean by "black hole".

If by "black hole" you mean an object sourcing a Kerr-Newman-like metric, then you have the problem that the distribution of matter in the distribution we see is not at all like the interior region of such a metric. The metric one can infer from the bulk distribution of the visible matter is best described by a Robertson-Walker metric.

Under time-reversal, galaxies in R-W fall through each observer-centric horizon, break up into dust and gas that in turn combines into denser higher-energy and lower-entropy states.

While this might seem a little like a "white hole" (defined as a time-reversed BH), since under time-reversal a stellar BH has Hawking radiation rush into its vicinity becoming relatively dense at the time of the bust-up of the BH horizon, the difference is on the other side of that point a much lower entropy neutron star or similar body emerges from the high-entropy BH. Even stepping back a bit, macroscopically, galaxies are a lot more structured than either Hawking radiation; nor is Hawking radiation more structured than the cold relic fields crossing into optical detectability of an observer in time-reversed RW or time-reversed asymptotic de Sitter space.

This is important: the densest phase of a universe like ours is (extremely) low entropy, while the densest phase of the black hole is (extremely) high entropy, especially if we measure just at their respective horizons. Entropy here is Boltzmannian: the log relationship between the observed macrostates and microstates that can produce them. (We could even test this directly by comparing the structures in the relic fields with Hawking radiation if we were to find sufficiently low-mass astrophysical black holes; we can however get some details from the ringing modes of BH mergers).

Additionally, we can consider curvature. The extremely low bound on our universe's Weyl curvature allowed by indirect and direct gravitational wave observations (so far) completely precludes a Kerr-Newman-like solution, where Weyl curvature will be very large. Our imaging of ever older galaxies does not reveal them to be spaghettified.

Finally, it's worth noting that while Kerr-Newman and Robertson-Walker can have optical horizons so can many other solutions. For example, there are optical horizons in the Gödel solution but we obviously aren't in a Gödel universe. There are also many solutions which cannot have optical horizons; a torus or Klein bottle universe is clearly different from a Euclidean one, although all of those can be everywhere flat and horizon-free. So I don't think one should promote the presence of optical horizons into the defining characteristic of a metric.

Do “dockless” bike hire systems actually work anywhere? There seem to have been so many stories like this.

Docked systems seem to work really well (e.g. London), presumably because you can’t take a bike without leaving your credit card details.
San Francisco's Progressive politicians are huge supporters of "cheap housing projects" as a percentage of permitted development (i.e. by blocking other projects), but are so far apathetic towards radically increasing the absolute number of below-market units built, which is what it would take to actually improve affordability overall. As it stands, below-market programs give disproportionate rewards (rent subsidies worth thousands per month) to a handful of lucky winners drawn off the waiting lists.
A large part of this is shitty engineering and product development. These products could be made so much better, but they suck instead.

Maybe instead of whipping up a pdf like Manafort that requires trust in the authors copy/paste & editing process it would be better to see the real email conversations incl. message headers. Not saying this isn't how it unfolded but this isn't <evidence> either.

Why go through the trouble of creating a pdf from different emails (he calls "letters") when he could just save the messages verbatim as plain text incl timestamps & other metadata. Some of the justifications for creating a homebrew-crypto says a lot. This sure is nonsense.
Every coder at some stage has run into this, right?

- A bug that disappears when you try to add some cout<< lines.

- Everything looks correct in debug, where (as mentioned) the variables are initialised to nice values like 0. When you compile with -O3, you get really large values instead.

- A bug that is rare enough that you have to run the program for a long while before it happens. And when it does, you haven't logged the relevant information.

- A bug that only manifests when you're not trying to show a colleague.
This is already happening - there's significant outflow from the Bay Area to other relatively progressive cities like Seattle, Portland, Boulder/Denver, Asheville NC, Austin, etc. In many cases they've turned those cities even more progressive in the process. My very conservative aunt in Portland complains about all the Californians moving in with their liberal politics. Colorado was a Republican-leaning swing state when I was in college, but it's turned quite Democratic lately.

They're replaced by domestic migrants from the Midwest, South, and farm belt, and by international immigrants from China, Taiwan, India, Vietnam, the Middle East, and many other countries. Interestingly, this "Bay Area conveyor belt" is perhaps the best thing that could happen for progressive politics, as many people newly arrived in the Bay Area come from very conservative regions, they often pick up more liberal values in the area (this is helped by selection bias - typically you don't pack up and move to a whole new city unless you are somewhat open to new experiences), and then they move on to other areas that were previously swing states.

nuisance of those bikes

Well, actually, the nuissance of the people not knowing how/where to put the bike away properly and/or being too lazy to do so or just being too selfish and not caring about others at all. Just like there's always this couple of car drivers parking where they shouldn't etc. But with these bikes it's just way easier to do. Just like it's also way easier for you or any one else to pick up the bike and put it away 2m further if that's less annoying, which is what I'd do if it would be in my way.

In the end I think the only solution is a mentality shift and more bikes, contradictory as that may sound. When enough people realize their behaviour is super annoying they might actually do something about it. In cities with a thousand times more bikes than in Paris there aren't too much problems like this because most are in the same boat.

there is such little room in the Parisian streets

Hmm, I'm not sure what part of the city exactly you're talking about and yes there aren't too many official bike parkings but in general I'd say there's plenty of room to tuck away a couple of bikes. Perhaps not always right in front of the place one wants to be, but still..

GPUs can only access pinned memory that is intentionally mapped into their address space. Also, each context gets its own virtual address space on the GPU, isolated from other contexts.

There can still be issues, but it isn't quite as much of a free for all as the above comment sounds.
Why wouldn't it be resolution dependent unless you specifically knew otherwise?
While I agree that a problem is exposed by these findings, let's not judge college grads by their ability to judge how well they fit employers' privately-held expectations of an entry-level employee. Companies suck at training, balk at its costs, but lament its effects on the sourcing of young employees.

Five Things I Did to Change a Team's Culture
Isn't it strange that people always seem to complain about a city or town suffering some problem as if it was a person. If you can't afford to live there, then don't. If you benefit from high property prices, enjoy it. If you grew up there and feel sad that you can't afford to anymore, then recognize that property rights exist to give the owners priority access to land so anyone who doesn't obtain property ownership has to expect that one-day they'll be forced out. They can create a bohemian utopia somewhere else if they want that. Why should it be tied to some arbitrary geographical area?
True, but it is also the price to pay when you use technology. You can't test everything. The TV, for example, is a new model from a big, quality brand (and in general it works well). Likewise, Call of Duty (the game that requires internet even if you play offline - not sure if this holds for all games in the series) is not a small title. So if these products by big companies have that shitty engineering, then most products with the same functionality probably will have similar problems.
Breaking Windows, perhaps?
I think the problem is Google. Between Page Rank, QUIC, HTTP/2.0 and AMP, Google is pretty much now dictating the terms of the Internet.

For instance, how much longer before Google only accepts email from the "Big Players?" (or drastically lowers the performance/acceptance of email from smaller sites?)

Terms like "progressive" have been around for so long, and used for so many different movements, that pinning down what somebody means when they use them may be difficult. https://en.wikipedia.org/wiki/Progressivism_in_the_United_St... doesn't even mention housing, so I guess it's not a core issue.

Things are trickier when it comes to production environments due to "data gravity", assuming you have plenty to backup I would stick to vendor's offering. Say for AWS you can use EBS Snapshots for instances and RDS Snapshots for SQL data, other than that S3 to other regions, etc. Depends on your usecase of course. Professionally, RTO and RPO requirements are to be defined before you choose what's the right solution.

I love to read ancient documents that have survived to our days, all the way back to the first written forms of documentation.

The conclusion taken from almost 4 000 years of written information is that indeed things change very little regarding human politics.
From Buffet’s explanation, it doesn’t sound like it’s inflation in and of itself that swindles the equity investor, but rising or falling inflation. I.e. if inflation were constant, the market would easily adjust, but when it rises or falls slowly over decades, investors are bound to make decisions that will turn out to be wrong in the future.

It seems to me that exactly the same is the case for interest rates: no rate is “right”, but falling or rising rates will force market participants to make wrong decisions:

* In a rising interest rate environment, all bond purchases will prove unwise, since the investor could have earned a higher rate by waiting a bit longer.

* In a falling interest rate environment, all bond selling (issuance) will prove unwise, because the issuer could have paid a lower rate by waiting a bit longer.

China Seeks to Repeal Presidential Term Limit
Eh. The government sure seems like a sect. I don't mean by itself, but some people treat it like one, and are becoming a part of the sect they've made up in their heads.

'Dockless' bikes have recently made a large appearance in London, too. They're suddenly everywhere, little orange ones. I'm not sure if it's the same company but it's the exactly the same principle. I'm quite surprised there are any left when seemingly the bike can be freed with a small bolt cutter.
The main problem that people have with this, is basically there is no way to verify that the design matches the actual implementation. At least there is no way you or I could do it. After the Snowden Revelations, trusting becomes difficult. That is why basically everyone who uses this instruction, mixes it with other data to make sure that even if this generator really was backdoored, the damage is limited

In case the significance is not immediately obvious: this means things have officially been set in motion to keep Xi Jinping in power for the rest of his life, which will mean a continuation of his style of Chinese policies for the foreseeable future.

That's not how it works, unfortunately. In a society, you have the right to be loud. You don't have the right to infringe on someone else's right of quiet enjoyment. It’s also common courtesy. Noise pollution is a real problem and it is pollution
You're right about blackboards but they make a hell of a mess with all the chalk dust.

The game updates situation... eesh. So many times when I've got maybe 20 minutes free to play a game and it wants to spend 10 of them downloading updates. One of the reasons I've come to love retro console gaming is that nonsense doesn't happen with PS1, PS2, Xbox, or Wii games.

For a lot of things dumb is often better and more reliable, especially at home: lights (though I do crave a master switch by my back door) and door-locks spring immediately to mind.

I haven't seen motion activated taps - the kind you see in public toilets - creeping into homes yet, but it's only a matter of time. Those things have always seemed pointless and overcomplicated to me, so if I ever move into a house that has them they'll be getting pulled straight out. What happens if you have a power-cut? I assume they'll keep working for at least a while, but sooner or later I imagine they'll run out of juice, and then what do you do?
Not easy to get into indeed but I find it a pleasure with some experience. Personally I find k/q nicer to work with than say Ruby as used in Rails.

He said his father flipped the house. He didn't said her father sold the house. Flipping a house involves the aim of making profit. So I assumed his father said nothing to the buyer.
But he can answer me about what his father did if he wants. On the other hand, I can't see the point of your comment.
If that was unexpected to you, I'll take it you don't know France very well.

People send stuff back to Africa all the time. I can't say anything about the bike (obviously), but I can tell you what an African friend of mine does for a living; in the middle of Europe.

He sends stuff back to Africa. What he does is he rents out a container on a ship and then collects the payload in small units. I advertises in the African community (mainly Togo) and sells small amount of space on that container. People want to send stuff to their relatives on the continent all the time.

I hope my mildly related anecdote was helpful.
It's unorthodox I'll give you that. When I think JIT I don't think "generates C code and hands that to a C compiler"!

However. Let's look at this dispassionately. This is only enabled if you use the --jit option. This means that this option can be switched on for production runs and not for dev and test modes. That seems like a very easy switch to flick.

Also, from reading the pages @petercooper linked to it seems the infrastructure is pretty non-invasive so far and leverages a lot of the existing infrastructure. Bugs have been squashed and all tests are passing.

I'm excited to try this on my own machine and see how it compares to 2.5 w/ Bootsnap, as I've posted here before I'm itching to drop Bootsnap.

There's only so much space in cities. Getting rid of bikes is the wrong move. Cars take up so much more space and cause a plethora of negative effects.

Interesting to see that this approach of vandalism is working. It's a shame people aren't physically strong enough to throw cars into rivers and from rooftops. Perhaps then Paris could be rid of its car problem.

> Just like it's also way easier for you to pick up the bike and put it away 2m further if that's less annoying

Which is exactly the point: I don't use those bikes, and still I have to get them out of my way. That's the nuisance.

That's exactly why parking in such places is illegal in the first place. But with those rental bikes this is very hard to enforce (because it's virtually impossible for the police to tell who parked the bike). And I think Gobee should have been banned in Paris because their whole business model encourages such a behavior in cities where there is so little parking places.

> Perhaps not always right in front of the place one wants to be, but still..

I agree, but that's precisely the issue. The problem here is that the model encourages users to just not care about the bike (because they're anonymous and because they don't care about the bike). Sure, in the end, if users were perfect Gobee would be great. But you know this is never the case as soon as there is some level of anonymity (why do would most websites have captchas then?).
Ultimately, technical limitations (is, problem would exist regardless of people) are not always (or usually) a limiting factor for companies working. Human limitations like having the wrong group in charge are the limiting factor. Ways around that are good, potentially.
None actually. If the NSA or anyone had managed to find a use for the sort of Quantum computers that are floating around the world would be very different.

However currently these computers are constrained by classical memory and read write operations are still classical.

I'm willing to bet it'll be a century more at this rate before quantum computing comes of age.

Since the 40s people have been hyping them without any sort of clear understanding.

Hitler's "Mein Kampf" was published in two volumes, in 1925 and 1926. It very explicitly defined the goal to eliminate Jews from German/Aryan lands. The "Final Solution" program was established in 1942 to implement the objective Hitler had previously set.

Lenin stated before the Bolshevik Revolution his goal to kill members of the bourgeoisie; he and his followers (such as Stalin and Mao) caused the deliberate death of more than 100 million people under their Communist dictatorships.

Pol Pot joined the French Communist Party in Paris during the 1940s, where he adopted genocidal Marxism-Leninism, as presented in the writings of Joseph Stalin and Mao Zedong. I'll let you look up the results of his work.
Show HN: Platform for underrated content
I would phrase it differently as competence scarcity.

It doesn't take many people to do soup to nuts businesses.. think WhatsApp's 50 engineers, Netflix's 100 person OCA team (if you don't think OCA is a standalone product you don't know much about technology business) doing 40% of the Internet by volume.. the vast majority of people just aren't very good that work in technology. Business governance grossly underestimates the effects of mediocre performance.

So the real question is why aren't governors trying to encourage WhatsApp and OCA style businesses, it's far more cost efficient. I understand why an organization itself empire builds, misaligned incentives.
