The distance between Launch Complex 39-A (LC-39A) to Landing Zone 1 (LZ-1) is 17-18km by road. During the Orbcomm-2 mission, the first successful landing of a SpaceX booster took place there approximately 10 minutes after launch, so one would have needed to go 100km/h in average by car to make it from launch pad to the landing zone in time.

Well, at this point, screaming about these not being mental models is about as useful as complaining about re-posted imagery not being actual "memes." (In the original sense of the word meme).

A mental model is something you use to make predictions so that you don't have to store all the nuances of a system in memory. It's a reduced-entropy representation of a phenomena of the universe that you have to interact with. It's a simple oracle. Newtonian gravity is a mental model.

These are recipes and formalized guidance, i.e., wisdom, for dissecting problems and presenting solutions. These are algorithms.

If you believe these will work, you have a mental model of the world that you have checked to verify these steps. The model that the author has of readers is that they will enjoy this post.

This is pretty mind-boggling, to the point of suspecting an error in the methodology. If it is just a language model, then it has no baked in notion of test time tasks. How on earth does a language model know what is required of it at test-time without fine tuning? How does it know that the test time prompt are examples of the task, and not some story prompt it's supposed to riff off in random ways?
Depends on the spin-1/2 particle. You need something to "grab it with".

Electrons "want to" stay aligned with magnetic fields[1].

Imagine two bar magnets, north to south:

NNNSSS e- NNNSSS, with an electron in the middle.

Spin the magnets around once. Tada! You've spun the electron too. The problem is that slight imperfections in the magnetic fields, as well as everything needed to move them greatly complicate what the actual effect will be on the electron.

To really observe interference patterns, you'll need multiple paths, and many many measurements to tease out statistics. In addition to the fragility, moving stuff around for each measurement is infeasible for this reason. Continuous beams of electrons split and merged by magnet fields, with a continuous parameter on of the paths that can alter how much it is effected is needed. And at this point what's happening to the electrons look a lot more like math than like straightforward rotations.

[1] Actually, they'll precess around the magnetic field axis, but if that axis starts close to the electron's axis, and is moved slowly, it will stay close.
All those businesses are allowed to open under the current state order. A few of them weren’t allowed until the middle of last week though.
It's not so much the 'C paradigm' that doesn't fit these machines, but really the ABI features C relies on to support separate compilation units. You could have a C compiler that's restricted to handling complete programs with no "extern" references of any kind (other than those that might be specified by some custom, asm-like mechanism) and it could absolutely match hand-written asm, given a good optimizer.

Yes, though normally aspirated pistons typically stay under 8500 MSL and very rarely exceed 12500 MSL. IIRC, you can make 75% power unboosted through around 7000’ MSL. I’d guess at least 90% of normally aspirated flight is under 7000’. It certainly was for me, even though my previous airplane could climb higher, it was slower up there, so I rarely flew it over 10K unless there was a screaming tailwind up high or terrible turbulence down low.

If I looked over all my engine monitor downloads for power settings under 35% while airborne, I bet the average would be under 1 minute per flight and it would be between 200’ and landing.

I don't feel particularly threatened or anything, but let me put it this way. Living in California and seeing more and more corporate advertising being done in Spanish (sometimes without even any English) leaves me with some concern. The concern is that some day, people(especially low-skill) will not be able to find a job unless they learn Spanish. Knowing Spanish will be a requirement to be able to compete for customer-facing jobs because they have decided that Spanish speakers should not have to learn English in this country, and that we should cater to them in the way of having documents, signs, etc. in Spanish. There is nothing inherently wrong with that, it's a nice thing. But the effect is that, eventually there is no need to learn English. You live in a community where everyone speaks Spanish already, so every business has to cater to Spanish speakers if they want good sales. So my concern goes out to all the people who grow up in this country who have only learned English, and are no longer at the point of being capable or willing to learn Spanish, who can no longer compete with born Spanish speakers or people who learned it from a young age. If that's the result we want, we should have been teaching Spanish from elementary school. But foreign language learning starts in high school, where you are only required to take a foreign language for 2 years, and it doesn't have to be Spanish.

While feeling 'american' is a subjective thing (I consider myself Albanian), There are still limitations. A naturalized citizen, can't be a US president, and in rare circumstances you can be stripped of your citizenship (it is called 'denaturalization').

So, yeah.... lets live it up to him to call himself whatever he wants, but calling him American is like calling

The list of living Americans who've done more to rewrite our future -- electronic payments, cheap spaceflight, electric cars, cheap solar power -- is pretty short.

From what I've read on the mailing list, a lot of the time was spent discussing the patch or patch series in general. That's what should be done when submitting changes.

What was confusing about it?

> And I don't see how using github locks you in, switching to gitlab, bitbucket or whatever is dead simple.

Well, with issues, metadata in PR discussoins, etc, migrating does take a bit of effort. What's simple about it? On the other hand, I could connect via NNTP to public inbox (or possibly gmane) and download 15+ years of patch series discussions in a couple of minutes.
Green Beret: Yet another classic Konami game [video]
We dance around this issue in the comments to every Haskell story, but the reason Haskell is hard to market is that it's bad. It's a research language being shoehorned into production by a few people who really love it. Some details of this have been given in this thread; let me suggest the following threads for more:

1) https://www.reddit.com/r/ocaml/comments/3ifwe9/what_are_ocam...
2) https://www.reddit.com/r/ocaml/comments/e7g4nb/haskell_vs_oc...

Yes, the Haskell community hates that guy and considers him a troll. But he does functional programming professionally as part of a private consultancy and wrote a book on OCaml. If anyone's equipped to understand what's wrong with Haskell, it's him.

Haskell has had 30 years to get its act together. Any benefits it has are drowned out by a sea of buggy tooling and accidental complexity (monads, etc.).

Ask yourself this: if there are literally billions of dollars in industry riding on writing efficient and correct software, and Haskell is such an obvious productivity win, why does it have a market share that rounds to zero?

Time to move on.
One of the most beautiful pieces of code I've ever read is this:

https://github.com/solvespace/solvespace/blob/master/src/srf...

If you have a basic understanding of spline and NURBS surfaces but never knew how you might actually implement that, well there it is. Incredibly readable IMHO.
I honestly think that Haskell's combined speed/correctness/maintainability is exceptional, none is in isolation, but I can't think of any reasonably production-ready language that has such a great combination of all three.

> Until you literally give an actual engineering (comparison of performance/reliablity/etc) reason that hypergolics are the wrong choice to make, this is effectively saying that "something should be different because I think so"

As with many discussions, we talk here mostly qualitative differences. Quantitative differences are harder to get by - for example, back of the envelop calculation says that 30 kg of peroxide in Soyuz landing capsule could be, roughly, replaced with 15 kg of hydrazine, so you'd have a 15 kg mass saving here, but in general actual engineering calculations are harder. I wish they wouldn't be such.

Given those very crude estimations and the practice, which shows there are no big unforeseen problems, we have a valid arguments for the alternative. It's an engineering argument, an estimation and not necessarily full calculations, and it's not effectively an arbitrary opinion. You may finally decide the issue using hard numbers, but since we don't have them now, the question stands.
It will be, but that’s not super relevant to this case. California didn’t enforce restrictions with any particular zeal and Newsom didn’t get mad about the lockdown protests.
>It's a bargain for someone who can normally afford to be paying more to store their insulin, sure, but for someone who's barely affording it normally, there's no difference between having it and not.

I guess you are claiming that someone who is buying insulin on a regular basis and has a refrigerator to store it, could come up with a couple of dollars to save their life, but not $12. (Oh and I guess you are implying that things like friends, family, neighbors, charities, churches, pawn shops, etc. etc. don't exist so they had no possibility to get $12.) In the article, there isn't any evidence that is why the police were called.

>It's a pretty racist approach really, since those people who aren't going to be able to afford the bump are likely to be black.

I imagine the economists who oppose price gouging laws would be very upset at your attempt to defame them. If you have an actual argument to make, make it.

>The same forces that push the government to not work on its stock pile affects companies just as much. ...

Companies try to maximize profit. For decades they have been removing inefficiency and making everything more lean - just in time delivery of their raw materials, only producing that they need, etc. So now when a supply shock happens during a pandemic, shortages happen and people die. High prices in a disaster are an incentive to make various investments which wouldn't pay off in normal times, but might have a large pay off later. A company in the US that makes protective gear almost went bankrupt after the SARS outbreak, because they had increased headcount and bought new equipment - he told both the Obama and Trump administrations that he wasn't going to be able to do that again. Both administrations ignored him.

>…The government has better means to think long term though since they don't need to continuously make larger short term profits

As I said before, if you want to make higher prices illegal, you better have a government be willing to spend its tax dollars on creating a stockpile (and excess productive capacity) rather than spending money on more immediate things that are more likely to get them votes. You can claim "government has better means to think long term" - but that obviously isn't what happened here - and considering the potential pandemics we've had in the last 20 years, you can't claim they didn't have enough warning.

I understand that people's sense of fairness is strong enough that some would rather have people die rather than someone make what they consider excess profit. So I understand when they simply ignore it when they read that economists (the ones who actually study the issue) are generally opposed to these kinds of laws. I think the majority of people who support price gouging laws though are not so dogmatic - they want large supplies of essential items available - they just don't understand the way to achieve that is to allow the price to go higher in times of emergency.

Yep, exactly this.

Usually local music shops or chains that sell gear also employ or rent space to instructors. Qualifications can vary a lot, which is why I strongly support the suggestion others have made to try out multiple teachers.

For lessons particularly, err on the side of thinking you’re not the problem. You’re paying hourly for this, and if you don’t click with the teacher it could be fairly expensive to “make it work”. Some people are also great artists but terrible instructors. That wouldn’t be so bad if it weren’t for the fact that they are also often completely ignorant of that fact.
It will depend a lot on the type of consultancy.

If they mostly get called to fix legacy projects they probably only see the issues and limitations imposed by frameworks.

If they mostly get called to jumpstart a new project they'll probably love frameworks that let them deliver quickly and reliably, since they don't have to worry about long term scope changes and maintenance.

This was called “desk checking.” You had to learn to read code and actually understand what it was doing. You may only get a few chances a day to run your code. I remember the feeling submitting my job (a deck of punch cards) and then getting my cards and a small printout back in a few minutes because of an ABEND (abnormal end, or crash).

I still do that, along with targeted experimenting on small bits of code I need to understand better. The skill of reading code and “running” it in the head seems forgotten now, though I think talented programmers usually get there.
the opposition usually sounds like this - "Microbenchmarks lie". On one of the past projects, the leading engineers and architects just loved that phrase and voiced it like a deep profound truth understanding of which was a hallmark of belonging to their circle of chosen. Any specific measurements showing issues with the supposedly brilliant architecture and implementation choices of that project (with many of these choices following the latest "best practices" fads published by some venerable technologists) were dismissed by that phrase just like by magic. Naturally that was one of the slowest, not to mention buggy, projects in my experience, and working in the enterprise space i've seen my share of slow and buggy.

That sentiment is so strange to me. There's a ton to learn to get into the industry, but "too much" requires some real thought. If an extra month of full time study could fix some software issue 95% of the time, are there any issues that you can think of that would be worth raising the bar? I'm not advocating that learning monads is the thing, but that a high barrier to entry isn't in and of itself bad.

I sincerely hope that software as a field matures to the point where maybe 50 years from now, hiring most of us working in it with our knowledge today would be like hiring a mathematician who never learned calculus.
Astronauts taking the nametags of the technicians helping them
Yeah there's definitely a capability gap. The issue is many of the capabilities weren't necessary or used on every flight.

Stuff like spacelab missions can probably be done using the ISS. Some of the military capabilities are moved to X-37.

Certain of the satellite launching capabilities of the shuttle were hampered by safety concerns post challenger/columbia.

The ability to retrieve and return large cargo is still missing, but it doesn't appear many people are clamoring for it. It'd be nice if we could continue to service Hubble going forward, but that's mostly nostalgia talking.

The Shuttle was supposed to do everything for everyone and it met with predictable results. The promised economies and launch rates were never realized. The safety issues inherent with the design made its continuation nearly impossible.

Having cheaper, mostly reusable launchers that have capabilities that people actually use is way more valuable.

Lightness is a hugely important feature in airplanes. I’m not sure that current battery tech is poised to deliver on lighter aircraft for a given mission range. An additional drag (pun intended) for electrics is that landing weight is the same as takeoff weight except for skydiving ops.
