> chances of collision are low

What do you mean? Taking a guess at answering that, electrons and positrons aren't electrically neutral: they are very very strongly attracted to one another, especially compared to

> gravitational collapse

so the probability of electron-positron annihilation immediately after pair production is in general extremely high! (In lab settings you need strong magnetic traps to avoid that.)

The "trick" in the star's core is to remove the electrons locally, or alternatively to convert the mostly-elastic photon-nucleus scattering with a much more inelastic photon-nucleus scattering.

I've described the former in sibling comments -- oxygen and silicon are present in these stellar cores and aggressively capture electrons. The positrons then are pulled outwards by electrons outside the core, and annihilate there. I omitted that an electron-positron annihilation produces two (or more) gammas rather than one, and that the photons can go in (different) arbitrary directions.

The latter is also an important contributor. The gammas in question are not even close to being in free space. They're in a region densely populated by high-atomic-number nuclei, and the Z^2 contribution in https://en.wikipedia.org/wiki/Quantum_mechanical_scattering_... dominates. If the region were all lighter nuclei (hydrogen, helium) the probability of pair production would be much lower.

Roughly speaking, in the absence of immediate electron capture by the nucleus the pair-producing gamma "hits", the momentum of the gamma is split three ways: into each of the electron and positron, and into the nucleus. Electron capture is in effect just an extreme inelastic collision.

In the no-electron-capture case, the heavy nucleus, having absorbed the "recoil" proportion of the gamma into its internal degrees of freedom, has several ways to get rid of that momentum, re-emission of one or more photons with lower energy than the gamma, or transmutation (which might produce neutrinos).

If the electron and positron pair immediately annihilate, they do so minus the "recoil" energy to start with; additionally they produce more than one gamma, and in arbitrary directions. Consequently, there is less momentum available for subsequent elastic collisions.
I'm sure my links aren't going to be relevant if I've misunderstood your argument so badly!

"Now, 150 years after the end of the Little Ice Age and with an extra 6.3 billion people breathing in air, absorbing oxygen, and exhaling carbon, the temperatures and PPM of Carbon are on the rise."

If the exhaling carbon is not significantly affecting the PPM of carbon, wouldn't you have written

"Now, 150 years after the end of the Little Ice Age, the temperatures and PPM of Carbon are on the rise."

What argument did you intend to make if not "6.3 billion people exhaling carbon is contributing to climate change"?

I think most people here think the value of WeWork is definitely not $0, but believe it’s well well well south of their last private valuation, and certainly well below what they’ll try to dump it on the market at.
When I lived in Poland before the wall came down it was just like that: gray. Then a Texaco gas station opened in the middle of Poznan, a tiny little slice of the West. A friend of mine remarked that she really hoped that the world would not change like that because it was so much color it was hard on the senses.

Nuance is hard to observe in the face of being shouted at, both views have their fans and both have a point.

Some cities would improve without advertising, others would show how bleak and gray they really are.
Yeah - they said that.. but then they had the whole $629k+ in the actual ask in the suit.. there is either more in addition, or they don't "accept" the pay-back (or just trying to make it look bigger to benefit the case)

There's a reply to that comment that casts doubt on its accuracy. I'm not sure which is correct but felt worth pointing out.
I don't see the benefit of reducing the lifespan of these certificates. In a world where everyone could use let's encrypt it makes sense, but that's not realistic for every company. I don't think it's worth the trouble.
Not directly, but I kind of assumed every business wanted to be the "third place" these days, so I extrapolated that to mean that WeWork wants to replace your "second place" with their offices, provide value by saving your commute, and then consume your "third place" entirely as well.

A ton of articles articles talk sideways at this idea, here are a couple (the second link is the most direct "answer" to your question but it's all interesting):

> WeWork seems to have zero plan to ever make money or be profitable

Last I checked, being up shit creek without a paddle isn’t illegal.

The problem with criminalising stupidity is differentiating genius and idiocy is often only possible ex post facto. We let investors take informed risks with their own capital. The SEC’s main job is making sure companies selling securities truthfully represent themselves.

There are many business models I never thought would work but which, due to scale, clicked. I’m sceptical about WeWork. But the way for them to die is for them to starve to death. If the Saudis (and Kazakhs?!) want to give them money, so long as they aren’t creating negative externalities, I don’t see the problem.
I don't think that possibly slow package manager is main Debian problem. There are more serious issues:

- bug tracker is email-based, not web-based, very old, and without keyword search.

- old versions of software

- unnesessary duplication: repositories contain Python packages that can be installed with Python package managers.

- Debian is not friendly to third-party software, to closed-source software. For example, to install Slack or VS code you have to add third-party repository and give permanent root access to your system to Slack Inc or Microsoft. You have a choice between backdooring your system or not using third-party apps. Compare this to Android that is also linux-based but provides a reliable and comfortable jail for every application except Google's.

- Debian doesn't protect your information from malicious software. For example, if you install third-party app, it will be able to read your browser's history and cookies in your home directory. Also, any unprivileged program can read hardware identifiers like MAC address, hardware list, disk serial number, BIOS data etc. This is perfect for tracking users even if they reinstall or change their operating system. Again, compare this to Android.

- package manager doesn't allow to install several versions of PHP or Node.JS if you are working on several projects. But for language like Python they allow to install two different versions, why Python gets such a privileged treatment and PHP or Node doesn't I don't understand.

There are projects aiming to solve some of these problems like Snapcraft, but as far as I am aware, they are not integrated into Debian yet.

Also, it is a bad idea to hardcode paths (like /use/share) within application, so that you have to recompile it to change the path. All applications should be portable by default to make installation into home directory easier.

Pet clownfish (like most marine species) are mostly wild caught - https://en.wikipedia.org/wiki/Amphiprioninae#In_the_aquarium

I believe Clownfish and blue tangs are all Least Concern. There is some concern that they might be threatened by overfishing as pets, but I'd say a much more realistic threat is habitat destruction (due to coral bleaching and pollution degrading the ability of damaged reefs to bounce back). Fish takes can be essentially embassies for the reef, and can be used to educate people on how important protecting the habitat is.

Hell, even for pandas, their status as zoo animals (and a national symbol) encourages China to protect their wild habitat (it's not like China doesn't have demand for more land).

And the problem with this approach is of course the dependency management. Just because you have the file for package X doesn't mean it will work if you're missing some of its dependencies. And those dependencies have dependencies etc. Which is why now we use e.g. yum and apt to install stuff, and not rpm and dpkg directly.
> None of what you said challenges the idea that it's a fraud

I’m not saying WeWork isn’t a fraud. I’m saying we have no evidence it is one.

People can reasonably disagree about whether a business model is sustainable. A bunch of people have bet one way. A bunch will bet the other. I don’t like WeWork, but I don’t like this idea that if outsiders disagree with the sustainability of a business model the government should shut it down.

If WeWork can realise cross-selling opportunities or unique leverage, through scale, over its lessors, it could work. It’s one thing to say something is stupid. It’s another to shut down the debate.

> Companies (well-run companies, that is) have surgical teams in spirit, in the sense that the more complex projects are taken on by engineers that have successfully executed the most complex projects in the past, and work with more junior engineers on coding those projects.

That doesn't sound anything like a surgical team to me. It just sounds like you're mixing experience levels to train new people.

As Brooks said (paraphrasing Mills), "instead of each member cutting away on the problem, one does the cutting and the others give him every support that will enhance his effectiveness and productivity." The anesthesiologist and radiographer and nurse aren't just less-experienced surgeons. They're not surgeons at all -- and I hope they're just as skilled at their jobs as the surgeon is.

There is a qualitative difference in results when you have a dedicated person in charge of something.

> In general, it would be surprising if Brooks had happened to be exactly right in all of his observations writing 40 years ago.

Why? Has human nature changed in 40 years? This isn't like reading Plato, where he simply made up things he didn't understand. On the contrary, I would be much more surprised if the nature of team productivity had changed in only 40 years.

The largest recycling center in California, with almost 300 locations, actually just closed last week:

It's believable in the "Finding Nemo" case because keeping a saltwater tank is a fairly serious hobby to begin with. Someone who wants to get a clownfish because they saw one in Finding Nemo has more hoops to jump through than someone who sees 101 Dalmatians and decides that they want a dalmatian, or who sees Peter Rabbit and decides they want a rabbit.

>we could power earth for almost a million years

With current consumption only. But we will populate its every corner, waste every amount on food production and fantasize what if we could capture just ten seconds a year (and terraform Moon/Mars). Humanity is a virus that cannot stop eating, reproducing in mass amounts and converting their host into a stinky factory.

I really doubt that so called Type II civilizations with Dyson spheres are a paradise to live in. Really advanced creatures would simply reduce their demand and live in the same beautiful place instead, occasionally feeding surplus energy to their scientifical interests.
>I wonder how cheaply it could be done for 1 customer

Depends on your definition of cheap. Your biggest expenses would be monthly bill to your fiber provider, then any necessary rent for backhaul sites, then the up-front cost.

I can't say for sure the monthly cost but it would definitely be in the low four figures.
This remark is incredibly American.
Discerning between the two cases is arbitrary.

Also since these would be WISPs (Wireless ISPs), it depends on topology as well (signals can't go through mountains, backhauls need to have line of sight to multiple customers, etc). It's a tricky balance of multiple variables.

The only significance of $10,000 is that it’s the amount that triggers reporting. Such transactions aren’t illegal or even suspicious. They’ll write you a check for the full amount and the other bank will accept it. There might be a hold on the funds for several days until the check clears. As another commenter mentions, you can open the new account first and do an electronic transfer which will make the funds available sooner.
It's rarely/ever paid off to engage with you on these issues, but if you genuinely do care, I have a 10 year history in which some of my comments have been killed, and in the majority of those comments it's been because of the very existence of disagreement, not because of the nature of how the disagreement was playing out.
Email could be free from spam if you configured your email client to only accept emails from people you manually added (and if SPF/DKIM was enforced). It's not clear how replacing SMTP with a different protocol would make the situation any better.

The reason why centralised chat systems can limit spam is that one company gets to decide who can and can't send messages to whom. Recreating that in a decentralised architecture is precisely the problem that needs to be solved, and the solution could then be used by email providers.

Now there are no technical reasons not to use SPF/DKIM, and recipients can enforce it more strictly, the problem seems to be determining which mail providers (i.e. which domains) can be trusted to stop their users from sending spam. Spammers have realised this too, of course, which is why a lot of spam comes from domains that are registered cheaply and quickly abandoned.

One solution that might be worth exploring is requiring that domain registrants provide a bond to their registrar if they want to send mail from that domain (grandfathering in all existing domains). The bond could be refunded after, say, 12 months of sending enough emails that recipients don't mark as spam.

The difficulty with this is creating a reporting mechanism that can't be gamed, either to unfairly cost a domain its bond, or to flood the system with fake positive reports to drown out the true negative ones. Fortunately, with DKIM, there is at least cryptographic proof that a given email was sent by a given domain.
Sure, but "acting as an employee" isn't set in stone. All it takes is arguing that they broke some rule, and they were no longer "acting as an employee".

While IANAL, I suspect that, if there were no stipulation from the jury, Oberlin might just cut her loose. So the jury wanted to ensure that someone with adequate resources would be on the hook.

There's also the issue that she's hugely popular among students, graduates, and donors. And generally, among people who care about "social justice" (as they see it). So firing her would have some negative PR consequences. Maybe even financial consequences, albeit not as much as $44 million.
> The present dumping ground of choice is Malaysia.

Use of the term "dumping" makes me seriously question the article's storyline. Plastic garbage is not "dumped" in Malaysia, it is sold to buyers in Malaysia. If you wanted to dump it it would be much cheaper to do so at source.

They are part of the water treatment process for municipal drinking water supplies.

Though I'm not familiar with the specifics and details of this case (and have seen the Veritasium video describing the use), it's reasonable to assume that these treatments would be applied regardless, and the shade balls are an effective countermeasure.
Water drainage is still going to be a big problem, as is damage/scratching caused by shoes, bicycle kickstands, trolleys, anything else with wheels that is pushed/pulled, you name it. Plus the simple fact that most sidewalks (at least here in the city) are often in the shadows of buildings.

It only makes sense to start thinking about sidewalks once you've covered all the roofs, which are way better in every sense.

Yeah, the story is usually like this:

* People found an ISP $NEWCOMER in an area where $ESTABLISHED has bad service and high fees.

* The newcomer invests loads of money into cabling the neighbourhood with fiber (or wireless internet) and offers deals with lower fees and better connectivity than $ESTABLISHED

* In a static world everyone would switch to $NEWCOMER and they'd make a lot of money, being able to expand to other places. But executives at $ESTABLISHED aren't stupid. They invest as well and lower their prices, too, just enough to be lower than $NEWCOMER.

* $ESTABLISHED waits until $NEWCOMER runs out of money. They rise prices again. It doesn't even matter if its price reductions mean $ESTABLISHED loses money in that region. The regions where there is no newcomer bring in enough cash to pay for the few regions with (temporary) losses.

Of course even if $NEWCOMER runs out of money, someone will buy their infrastructure and offer similar services, but there are more components in the competitive moats of established ISPs like (local) government granted monopolies in exchange for providing public buildings like school with free internet, or the bundling of streaming services with internet deals. Those moats usually are wide enough that there is no avail for small ISPs to break through. That being said, if you break through the moat, it's an insanely profitable business. DTAG had to invest tons of money until they got there and now they are in the place where the big ISPs can't harm them any more and the american daughter company is now the favourite of the DTAG shareholders.
