> Your definition of “blow it” seems silly and inapplicable. When you have a huge financial parachute behind the scenes, you have room to absorb losses from poor investments, and again the cases when legacy money is mishandled so badly as to lead to ruin are extremely rare and over-popularized in media.

I'm not just talking about total financial ruin, I'm talking about staying rich over multiple generations. Over that timeframe, you'll have wars, market crashes, sovereign debt crises, currency crises, riots, and so on.

Let's say I give you 10 million dollars, which puts you in the top 1% in the US. Over an 80 year lifespan, that's 125,000$ per year. In the period from 1900 to 1980, that money lost about 90% of its purchasing power. If you do "nothing", at the end of that period, you will be poor.

So you have to invest the money. Who do you trust? The government? Untrustworthy. The stock market? Highly volatile. Gold? No yield whatsoever. Real estate? Requires upkeep, vulnerable to structural change. Diversify? You may not even beat inflation. It's easy to say in hindsight what is an isn't a dumb investment. You're biased by living in the tail end of the best century of the best economy in the history of humanity.

> Getting one’s rich parents to fund a dumb start-up idea that wastes millions crashing and burning, and then reluctantly using family connections to get a $400k/year job in a finance or white-shoe law firm is not at all any version of “blowing it.”

You think Wall Street just hands out $400k jobs to rich kids because they went to some prestigious school? You believe lawyers are hired on the basis of their inheritance?

I'm a current student in the Harvard Extension School concentrating in CS and can answer any questions you have.

Edit: Should say for the record the Harvard program is not a scam, highly reputable (Harvard), classes / professors are the best I've ever encountered, students range from duds to awe inspiring as most places do.
Salaries might be up but you can get more done now with smaller teams (as in: only the founders). Some startups are possible now without technical co-founders that were not easily possible a few years ago.

edit: I'd say there is way more competition (for talent & market/use-cases) though among startups as well as between startups and FAANG.

Foreign tourists trying to get to the airport have been attacked.

In this clip, you can see protestors/rioters punching the tourist in the back several times.

The chaos was at a train station called Tung Chung, which is a link to the airport, but the protestors trashed the station, flooding it and threw objects onto the railway line.

Apparently they did dump some of the fuel: "While dumping some of the excess fuel, ..." (https://en.wikipedia.org/wiki/United_Airlines_Flight_232#Cra...)

Possibly the pilots were reluctant to dump too much fuel, since the two remaining engines were their only method of steering the plane. A lack of fuel was the last thing they needed.
That’s a great idea. We’ll certainly consider it in the near future.
I'm not entirely convinced this is the argument.

From what I've read so far, it seems that ESA was uncomfortable with the possibility of a collision to a degree that SpaceX could possibly be quite comfortable with - ESA wants > 1km distance, whereas SpaceX might be comfortable with much closer - they are quite different constellations.

Who has the right to dictate who has priority / which criteria is the right one?

I'm going to assume that the cost of ESA's satellite is much greater than SpaceX's StarLink module so obviously they have much more of an interest in preserving full functionality - BUT avoiding collisions is in everybody's best interests. Who is going to use their fuel? Who has right of way, and to what terms?

The “more to it” is that ESA is gearing up to request funding for their AI project, billed as an automated tracking and avoidance manoeuvre planning system capable of handling the vast numbers of objects and debris expected to be in orbit in the near future.

This was not about “SpaceX refused to move” but “we need money to build this automated system so we don’t have to do it all by hand,” and an additional level which is, how should the various satellite operators make their orbital parameters available to interested parties?

The situation is that ESA didn’t even know what kind of object the track represented, and they had to contact SpaceX to ask about it in the first place. Their job would have been easier (whether manual or automated) if SpaceX made the orbital parameters available for automated queries.

The last thing this is about is SpaceX being “arrogant” or “refusing to move a satellite.”
The very concept of functors was created to describe sets that did exactly that. The functor laws only require that there is an operator that can wrap a value from one category into the functor's target category, that mapping with the identity function is the same as the identity function, and that the results of composition of mapping with two functions is the same as the results of mapping with the composition of the two functions. Set fulfills these laws perfectly. There is no law for maintaining cardinality, because the functor laws don't care if cardinality is a concept that even makes sense for the target category in question.

I had the same experience and was disappointed. But a good mesh app is inherently difficult to monetize!

Combining mesh over some/several form(s) of 802.11, Signal protocol public key distribution "locally" via QR code, and Delay-Tolerant Networking (Cerf et al. 2007) would be the holy grail (and would have no reliance on SMS or phone number) and also could not be monetized. Which is a damn shame, because it's eminently technically feasible, but complicated enough that I'd probably need a professional team to implement.

Yes we do. SQLite is in the roadmap.

Although it’s database-agnostic, we do realize that a lot of the use cases is about generating database-specific SQL based on DBML code. So we’re working on introducing dialects to the syntax so that it closely resembles specific DB better (e.g this DBML is of MySQL dialect).
I've maintained my 758-day streak freeze for basically the entire summer using streak freezes from accrued lingots. Not sure I still deserve the streak, but it's definitely kept Duolingo in the front of my mind even as I've taken a break (and I'm getting low on lingots, so I'll be getting back on the horse soon).
Have they stated anywhere they lost control of their satellite, that it was inert? It was under power and reportedly performing a test maneuver.

If they didn’t have control over it they could have easily stated as such to ESA and avoided any bad PR at all, or even just in response to this story.
I used a simple mobile "burner" and was fine to authenticate. I bought bunch of $5 cards with cash in a small store and used this one in my dumb flip phone bought on a flea market few months ago. I am certain to a high degree that's pretty enough setup to stay under radar.
> If you’re suggesting that it’s easy to go from being rich to being poor, I think it would be useful to find data that examines how many people born rich become poor over time, and how many people born poor stay poor over time. Like, backing that claim up would make it more believable.

It's not easy to get data on the very rich. However, the top fifth of the population is about as likely to become poorer over time as the the bottom fifth is likely to get richer over time (page 6):

If that is your standpoint any form of activism like this is stealing from the community.

On the whole, this is probably one of the least harmful things they could have released publicly.
Without the selling point, it wouldn't have been adopted and we wouldn't be talking about it.

I think we're talking past each other, and perhaps I didn't make my original point clear: Attributing a lack of trust to specific technologies themselves is a red herring that obscures the deeper cause for the trend. In fact I'd go further and say that the usual pattern is the adoption of insecure naive technologies, with demand for security features only occurring after bad actors arrive. (Interesting link, I'll have to check it out)

I think the bigger picture with transaction systems is that such trust was never scalable in the first place. Businesses took computing technology and naively tried to scale up the old way of doing things - knowing a limited number of people by face. Hence national ID numbers and surveillance databases with [social] credit scores - to keep it hard to "run away" as running away was becoming easier.

And that worked for several decades while that network was effectively small so nodes on it could be trusted. But rather than ever rearchitecting for the realities of the new environment, they simply attempted to fortify its fundamental flaws (hence "identity theft"), and now creative destruction here we go.
I worked on a project with similar requirements. I just serialized the data with protobufs, encrypted it, and stashed it in S3. It was sensitive data so this also had the advantage of being easy to secure and audit.

No point using a relational db for that kind of thing.
Do we actually know that dark matter doesn't interact with itself or other matter, or do we just have an upper bound on how much it could potentially interact? And if so, roughly what is it?
Also Foundation DB supports mongodb clients. It also powers iMessage.
Interesting. Or perhaps it would create more balance issues. Regardless, it sounds like it was considered by someone with more experience flying airliners than myself.
You may hold a different opinion, but I think this is going to be reasonably effective in making the bus company fix their app.
The bigger issue is that ESA is coming up to an important administrative date in November where their future budget will be determined, and they want money for their automation program. So they have to portray space as dangerous, ESA processes as desperately in need of improvement, and this specific example of a super expensive research satellite coming close to part of a future megaconstellation makes for great attention-grabbing headlines.

That it was SpaceX that ESA got to throw under the bus was the cherry on the cake.

Chinese EV maker Nio dangles ‘zero down payment’ to pursue sales target
The track record of experimental designs deliberately intended to push the boundaries of reliability really does not give us any idea of what to expect for the future.
I think a few things hampered Nintendo. Their (laudable) commitment to backwards compatibility led to them getting stuck behind the curve technologically -- the POWER architecture they stuck with from GameCube (when it was a mostly mainstream choice) to WiiU (when it really wasn't) and the older pre-Cortex ARM designs they were using in the 3DS years after Cortex was shipping left Nintendo of the position of not being able to really ride the bulk of the improvements happening in the marketplace. (It's notable that the Switch is an abandonment of hardware-based backwards compatibility in favor of Nvidia internals that wouldn't look out of place in an Android tablet.)

And because Nintendo prides themselves on being a family company, in much the way that Disney does, they had less of a tolerance for looking the other way at just how bad other users can be. Microsoft would just throw out an "Online interactions not ESRB rated" warning and moderate the worst of it after the fact when building Xbox Live. I don't think Nintendo ever saw that as an acceptable option.

> I just have to think of someone attacking a random person in the street, then choking them, then realizing the mistake but not letting go because they already attacked them and they might retaliate, so it's best to just "see it through". It boggles my mind.

Well, when you left so many half choked people around, no wonder when so many want to kill you.

See, US always carries through its promise to "finish off" old adversaries. Saddam was once a US ally, but much more of a frenemy. US waited for decades to dispose of him.

Ghaddafi, almost the same, once got a grudge against US no longer giving him carrot, and 30 years later, bang!

Castro - they tried for whacking 20 long years, to no avail.

Noriega - again, it took them near a decade to smoke him after their flirting with him went bad.

A ton of other harebrained dictatorship in Latin America ended very similarly, the moment they antagonise US, the clock is set ticking. US may even keep supporting them enthusiastically, while supporting a coup against them: Arellano was a US darling until US threw a bananagate at him, then deposed his deposer. It went even more wild in Salvator, where US sponsored a free trip to Hague for both Daubuisson and Duarte, after supporting them both against each other.

But ultimately that logic is both self defeating and amoral. Any war, no matter how tiny and "manageable" it looks like carries a lethal risk, eventually you will get killed no matter how tough you are.

I can bring a parallel with life in a lawless city. People who survive the longest are not the strongest ones. The "tough guys" on other hand, almost always tend to get killed in meaningless fights over stupid things because they can not concede a thing.

Like a crime king of mid-naughties Moscow who was killed in a fight over... a parking spot, by a single hit to the head with a stone...

I can not imagine that somebody who comes with such policy lines is an actual military man. Nobody who went through a real war, and not ended up a psycho, would ever meaninglessly provoke an enemy.

But that reeks of doctrinalism of political theoreticians dressing up as generals. Very much along the lines of thought in places like RAND institute, or the more MBA-brained parts of Westpoint.

> What is the current theory how superconductors work?

The best general model of superconductivity I'm aware of is still the BCS model:

https://en.wikipedia.org/wiki/BCS_theory

This model basically says a superconductor is a Bose-Einstein condensate, where the Bose "particles" are pairs of electrons in the material that are entangled via an interaction involving low-energy vibration states of the material as a whole. The problem is that this general model doesn't tell us what the critical temperature for the Bose-Einstein condensation is. We have to find that out by a combination of experimentation with different materials, and more detailed extensions of the model that test various hypotheses about what kinds of material properties should affect the critical temperature. This paper is just a recent development in that line of research.

But it was actively changing orbits https://twitter.com/planet4589/status/1168637324592328705?s=...
No.

All deorbiting objects (“satellites” or debris, whatever you want to call them) are going to pass through the orbit of the ESA satellite which is intentionally in a very low orbit.

It is the ESA that actively moved into that orbit by design, intention and active navigation. SpaceX intended their satellite to lift to a higher orbit but it couldn’t make it, so it is being deorbited by atmospheric drag.

All orbits at the same altitude will cross at least twice. This is not a deliberate act of interception but just part of the way orbits work.
That wasn't inert on the contrary. https://twitter.com/planet4589/status/1168637324592328705?s=...
One of the benefits of FRAM is that you can put it through extreme radiation and still have it work afterwards. So you can put it in a medical instrument that undergoes gamma ray sterilization, and it will still not only work but also retain the data.
For an open source, anonymous version of this check out the Briar Project: https://briarproject.org/how-it-works/
we make a lot of use of FRAM in our embedded systems. It's great stuff. With huge amount of write cycles it simplifies the data structures you need to store compared to page based / lowish write cycle memories.
You need to update your book to reflect the reality of deorbiting a dead satellite.

There's not much to disagree on the odds. Trajectories are known, uncertainties too and therefore probabilities of collisions can be calculated.

Any disagreement here is easy to reconcile, whose assumptions and methods are more accurate?

The disagreement is on the importance of the odds. SpaceX might be OK with a 1:10000 (or whatever) chance of collision, the Europeans want it lower.

The Europeans could in the future force the issue. Move, or we'll fine you and forbid you from launching off of European sites and ban EU companies from using SpaceX.

Everyone intentionally placing their satellites in VLEO is going to be spending more fuel simply staying in orbit against atmospheric drag than they they will spend on avoidance manoeuvres.

This ESA satellite is in VLEO by design, which means every piece of space junk is going to present a threat to it.

Once ESA has secured funding for their navigation automation project (funding to be decided in November), we should hear nothing more about potential collisions with the endless rain of space junk from megaconstellations.
