$2m is the cost on Starship's Wikipedia page, which implies 10 Hubble masses. Now, I am not talking about taking 216 mirrors and combining them into a single mirror pointed at a single camera, but actually 216 self-contained mirrors and cameras. That is, whether they're put closer together or further apart, they'll be interferometry based. What's important isn't how well-aligned they are, but how well they know how they're aligned.

I think the reason these things keep getting built on Earth is because until now no one has dared to dream of putting that much mass in orbit for that cheap.

Without commenting on this particular event, the passive voice typically doesn't identify the actor and can thus be used to omit or obscure responsibility.

Consider the classic 'mistakes were made' vs. active alternatives such as 'we made mistakes' or 'they made mistakes'.
Between your comment and the GP, it's easy to see that any "distance learning" is only a stopgap that we've been forced into, and is not scalable or desirable for any length of time.

It tells the driver to take over when it can't interpret the situation.

Total self driving is far in the future. Realistically in a few years we can get to the point where the car can drive itself in usual situations, but the human is needed for anything unusual.

I had a weird positive experience with Google lately. An account rep messed up all my AdWords (I still call it that) campaigns and blew $900 on worthless mistargeted clicks on Christmas Eve 2018. My request for refund was denied, so I chargebacked and got banned (who cares).

I need to use AdWords again next month so I reactivated the account and asked for another appeal. They immediately deleted the $900 debt and unbanned me.
Were you homeschooled before the age of 12?
From the article:

> On the evening of June 9, 1990 — a month before Patton turned 18 — Patton and a Klan leader took a semi-automatic TEC-9 pistol and drove to a synagogue in a Nashville suburb. With Patton at the wheel, the Ku Klux Klan member fired onto the synagogue, destroying a street-facing window and spraying bullets and shattered glass near the building’s administrative offices, which were next to that of the congregation’s rabbi. No one was struck or killed in the shooting. Afterward, Patton hid on the grounds of a white supremacist paramilitary training camp under construction before fleeing the state with the help of a second Klan member.

Now, imagine that this same story had happened, but the young man 1 month from his 18th birthday was black. He would have been tried as an adult and put in jail for a long time. The justice system has a long and storied history of going easy on white supremacist hate crimes.

The fed can help with liquidity (i.e. ensuring that whoever needs to fund itself has liquidity by flooding the capital markets with cash). It cannot help with solvency though (if you can't afford your debt because your revenues collapsed, no private lender is going to lend to you, even if they have the capacity to fund the loan). The interest expense is low, but when your debt becomes due, it is the end of the game.

They had decided how, it just turned out they found a better way after giving it a try.

>I suppose I just imagine most people have an idealised view of their child's education, and then decide they need to home-school to realise it. But perhaps that just wrong, I've no experience, first-hand or otherwise.

They do, and they also have idealized views of their children. If you go into home education with a rigid plan of execution, you (and your children) are likely going to have a bad time.

Teaching is hard. Striking out on your own vector of pedagogy is a large risk that, if done well, can yield very large rewards...it can also be a disaster.

> Our problem is further complicated by the fact that we’re not shipping an app but a framework for others to use in their own apps. We have to be mindful of the impact our technology choices have on our customers, such as the potential for harmful interactions with their code, and user-visible performance impact in terms of CPU and memory usage.

Without knowing the details, framework-as-a-product argues strongly for a native-only approach to me. Xcode + ObjC/Swift on iOS and Java on Android.

The article(s) might make a better case for polyglot by talking in detail about what the framework does in more detail. The bar for going in that direction would be very high for me.

I agree that they should have never been shuttered by the government, but the die has already been cast. They can't undo the damage. What they did is equivalent to a scorched earth economic response to Covid-19. We're going to have to rebuild every industry we hurt. Some of those industries may never come back to the level they were (i.e. cruise ships). There's also fundamental shifts in consumer patterns that are occurring and will continue to occur as a result of economic uncertainty, trade battles with China, price shocks in response to supply / demand shocks, etc.

In the U.S. we also need to shift our consumption based economy to become more of a production based one, like we were 40 years ago. That kind of shift doesn't happen overnight.

200 years ago we didn't need timezones because we couldn't communicate or travel fast enough or often enough for them to matter. With railroads and telegraphs the level of granularity required for "some time 300 miles away" went from days to hours and minutes. No one in the U.S. west wanted to be told "The sun is at its zenith around 8 a.m. for you." For most people talking about time in their day to day lives it's far more useful to communicate a relative time of day with people near them than to communicate an absolute moment in time and do the math to figure out how bright it is outside.
Police and soldiers more commonly in my observation develop a type of cynicism or nihilism.

The data regarding number of deaths is severely tainted though. Many doctors have claimed(this is also mentioned in the OP video) that their administration pressures them for including COVID-19 in causes of death.
It's really hard to be racist when your boss is Filipino and your coworker (who outranks you) is black and you're stuck in a small room with them all day long. You see pretty quickly that everyone is fundamentally the same and we all want the same things. Prejudice has a hard time surviving a strong dose of reality.

Sure, there are racists in the military, just like with every given set of people you could care to name. The Navy absolutely does not put up with it, though, and it's a career-ending mistake to act on any of those leanings.
Agreed. This hate crime was committed 1 month from his 18th birthday. A defendant that wasn't white would have been tried as an adult and thrown in jail for years.
Another complication to the normal "pass structs by pointer" is that small structs are actually split up and passed in registers depending on the platform ABI, which can be more efficient in certain cases.

I do think it is technically wrong to call it dogma - the decimal is a geometric series with a limit, right? And limits have an unambiguous definition, it's the smallest value that the series approaches but never exceeds as it tends to infinity. I think the part that is admittedly weird is that the notation "0.999..." refers to the limit as the series tends to infinity, and it kind of hides that fact from you. Even just writing the geometric series down and plopping "infinity" as the value for x would be wrong, as it's the limit that is equal to 1 as x tends to infinity. So there's arguably more hidden notation than the ellipses implies, but nothing is pulled out of a hat here or defined for definitions sake.

When a downturn like this happens, the Federal Reserve lowers rates to encourage spending. But at the same time, people are less likely to hold corporate debt and instead hold cash. People are less likely to hold corporate debt because the corporation has less revenue to service its debt. In the case of a (highly) public company which doesn't have profits, if Uber were to try to sell bonds, the spread over, say, treasuries, would probably be above 8-10%.

In other words, corporate debt isn't priced according to lowered rates. It's priced according to what bond investors would need to be paid in order to adequately compensate for the risk of Uber going bankrupt.

The only way the Fed would help would be if the Fed bought Uber's bonds, but that would require Uber to be investment grade, which would be laughable, or a "fallen angel", a company which was investment grade before the crisis but has since been downgraded.
You misunderstand socialization.

You're not learning explicit skills. You're learning implicit, semi or involuntary communicative behaviors. Similar to those not learnt by animals who cannot behave properly because they were not socialized when young.

But for humans it's more involved. We are essentially talking about a certain common cultural fabric and the problem is that if you don't fit that fabric, you will be at a disadvantage. Making friends, dating, interacting with coworkers - there's a critical window to keep your kids from turning into someone the average person would perceive as "weird". And the behaviors are subtle. Things like posture, voice tone, word pronunciation - I think "nerds" evoke a certain uncanny valley response in some people. That's a risk of homeschooling.

It may not be ideal but human nature is such that humans typically expect, on average, some degree of conformity. If personality and behavior are multidimensional vector, we're talking about an emergent clustering force, transmitted by socialization.

Edit: I speak from the experience of having spent years trying to catch up.
For a lot of people, schools are closer to a daycare -- that's still going to be an issue.
Yeah – I meant “[the brother] is Randall Munroe”.

Is it so unrealistic to think that an abused child would fall into a world of hate? Yes, participating in a drive-by shooting is absolutely horrible, but if he paid his dues to society through our legal system, why should this man be unable to run a business?

He clearly shows remorse for his hatred. I am not defending nazism in the least, but I think "cancelling" someone who made absolutely terrible decisions as a literal child is not a healthy way for our society to operate.

> This article is about cars driving in simulation, not on the real streets. But I do wonder how they can introduce truly "unpredictable" events in the simulations.

Like normal SW:
Requirement: navigate this road with those signs.
Test: Put the same signs as in requirement. Check that car navigates correctly.

> I don't know anything about self driving cars, but it seems like solving self driving cars isn't far off having general artificial intelligence. How well does a car react when there is a construction flagger telling it to turn around, or when there is no signs and the traffic lights go down due to a power failure?

It either continues or stops. When the traffic lights go off it uses the computed right of way.

It's the same for self driving cars. It is like every SW designed after a set of requirements: you feed it with something not specified in requirements and whatch it crash or spitting an error message.
Tough situation. I can understand him trying to hide the mistakes in his youth. I certainly wouldn’t want to be haunted by whatever idiotic things I did or said as a kid, although they definitely were nowhere near what this guy was doing.

Admitting such things before building a career would instantly be a non-starter. I also think as a society we have to acknowledge that rehabilitation and forgiveness needs to be possible, especially for mistakes we make as kids. The mob seems to want people like this to be disappeared, which is unfortunate for a country so influenced by Christianity, in which forgiveness is a prime value.

On the other hand, this guy seems to have really been a subscriber to some bad, dangerous ideas, and more importantly, he doesn’t seem to have done much to atone for it. Donating to the synagogue, getting involved with the community or somehow seeking forgiveness by acknowledging his mistakes would have been better than just hiding it.

He didn’t need to do anything public that would dig up the past either: I imagine he could have donated or helped the synagogue in an pseudonymous way. Certainly the people he hurt would be far more willing to defend his rehabilitation now if he had done so.

I'm a teacher in a low-income rural area in the South and, try as I might, there's still some students I haven't been able to get ahold of. They don't have phones, or just didn't join Remind for whatever reason, and their parents didn't give me an email address. Hell, I've tried calling some on the numbers the school has on file, or that they gave me, to no success. It's quite frustrating from the teacher's perspective too, as I really just wanna make sure they're doing OK and that they get their stuff turned in... Though our administration did pretty much assume to expect nothing once we went to packets/online work, despite how much they threatened to place any students who didn't do it in in-school suspension or even fail them.
I don't think this analogy is applicable. The government hasn't banned air travel, and the drop in demand is more of a second order effect as the result of minimizing potentially detrimental behavior (spreading the virus).

In general I don't believe the government is required to compensate businesses if regulation results in loss of business and possibly the loss of the business. As an example, look at CFC bans and fuel/emissions regulations. A company may suffer a loss and/or go out of business because of a regulation, but they can't demand compensation for that from the government.
The same way a startup chooses any hosting platform. They pick who their VCs tell them to pick because it's all a slush fund. Zoom's losses are another business owned by the same VC's gain.

Another way of looking at it is as an additional, backdoor tax. And a regressive one at that, since it disproportionately affects the poor.

A day's wages is a pretty heavy tax.
That's the case for many tech companies, why does Twitter need thousands of employees?

Turns out there's lots of employees to do all kinds of things, the app side is only the tip of the iceberg. There needs to be people collecting metrics and analyzing them, people building the platform that employees use to deploy code and run batch jobs, maintaining infrastructure (IIRC Uber did onprem -> cloud -> onprem), people interacting with customers and drivers, local expansion teams, and so on.
More layoffs are coming. I know PayPal is going to shift a bunch of jobs from San Jose to Austin when this is all up. There will be way more layoffs or relocations.

This reads very closely to just blaming parents for not being good enough, and not raising good enough children.

While I’m sure family culture is incredibly important, we shouldn’t forget that growing up in such a culture is an incredible privilege. One enabled by having moderately wealthy parents.

Being moderately wealthy doesn’t mean having large saving or a fancy house. It means being able to provide 3 meals a day and clothes for your children. It means having enough time after work to pick up your kids, and read them a bedtime story.

There are many people living in the western world who aren’t that wealthy. Who have children and work 3 jobs just to keep them fed. You may even be tempted to say that the parents are irresponsible for raising children without proper financial stability, but that doesn’t help the children they have. It just provides an excuse to ignore a real social problem.
There are some weird rules like that for floating point numbers too.

8% of what? All employees, or engineering? (435/0.08) ~= 5400, and Uber's S-1 filing says they had 22,263 employees as of 31-12-2018.

(ed. - article says 27,000... but Uber's had three low-hundreds firings chunks tallying ~1260 total over last summer, and said they were freezing engineering hires. Were the extra 8k hired in the first half of 2019?)
Would you like to continue your line of thought all the way and return to having poor children work in factories?
You are downvoted, but you are actually correct. 0.999... != 1 can be true in nonstandard analysis. So if using standard analysis over nonstandard analysis is a convention, then ultimately 0.999... = 1 is a convention too.
