I'm going off of very limited KSP experience here, but...I don't understand how a centrifuge could possibly get anything into orbit. If you impart an instantaneous delta-V to an object -- such as by firing a rocket engine for a short time or flinging it from a centrifuge -- then AFAIK its orbit will always return to the same point from which it thrusted (unless you launched it on an escape trajectory). So, ignoring drag for the moment, if you launched a rocket from a centrifuge with orbital velocity, it would complete one orbit before hitting the back of your centrifuge.

TFA mentions "the company has future plans to add a rocket motor inside the projectile to provide for orbital flights," which seems like it could be the solution, since it would allow the projectile to raise its perigee by thrusting at apogee. However, it also mentions "the rocket component is not a necessity for putting an object into orbit"; am I misunderstanding something or is the article just blatantly wrong about that?

Additionally, if we don't ignore drag, this seems like a really difficult/inefficient way to get something into orbit. A traditional rocket increases its velocity as it ascends and the atmosphere gets thinner; the vast majority of velocity is gained after the rocket has exited the atmosphere completely. Since drag increases with the square of velocity, it is really important to keep the velocity low(ish) until there's less atmosphere to fight against. Whereas with a centrifuge launch, we have to deal with orbital velocities in the thickest part of the atmosphere (plus the the extra speed needed to make up for the massive amount we're going to lose to drag). This becomes an easier problem (but still a problem) if most of the orbital velocity is in fact coming from the rocket engine rather the centrifuge...but then this starts to sound a lot like the "launch a rocket from a balloon" idea that always seems to get shot down: https://space.stackexchange.com/a/1641/17612

I'm not an aerospsace engineer, so I'd love to know how I'm misunderstanding this, because I know people much smarter than me have thought through these things. (The more I read the article, the more I think perhaps the author doesn't realize there's a difference between "exit[ing] the atmosphere" and achieving orbit.)
> Abuelsamid said breathalyzers aren't a practical solution because many people would object to being forced to blow into a tube every time they get into the car.

Also those are super easy to defeat. People who have them usually just get someone else to blow in it or just blow into a bottle and then squeeze the bottle into the tube.
It would be better, in my opinion, if instead of having a single implementation of a source control app there should be a specification not just for the source control itself but for SaaS products for collaborative development around that source control model (the latter wasn't obvious until GitHub built it though).

Education in the U.S. has been systematically defunded/chronically underfunded and bureaucratically shitfucked by one of the two major political parties in the U.S. for the last 50 or so years.

Our last secretary of education is the literal heiress to the largest MLM scheme in the nation.

Truly, I cannot imagine why you're at all surprised that our education system is in shambles unless you've been living under a rock.

I mean, we have kids that don't even get served lunch at school, for reasons quoted as "it would make them too used to communism"

Can you imagine why kids that don't even get to eat might not be giving a single shit about caring about school?

J1939 or CAN is a network protocol many vehicles use for control module to control module communication. The “standardized system” you were commenting about is referring to access to the server side info. Currently manufacturers can pull telematics data like odometer, trouble codes and PIDs (data items like speed, brake status and very much more) which helps with service reminders and streamlining the repair process. Aftermarket shops are at a great disadvantage in this regard.

That term is heavily centered on games, anime, manga and nerd culture. None of which I have interest in. I've been to Akihabara once which I'm sure you are familiar with, and I have no interest in going back.

What do you think my obsession is? I'm specifically in Japan for political reasons. Maybe it's obsession with society, rather than culture. I'm in Japan because I care about individual responsibility, and Japan doesn't trigger me.

I actually minored in architectural history. My point of contention is whether it is the architecture, or that this unique architecture which is in Japan?

And yet it only exists in Japan.

Also, just because people have good intentions in loving something doesn't mean it's good. That's what leads to orientalism. Did you know Memoirs of Geisha was written by an old man from Tennessee?

If you somehow don't understand the genocide The Killing Fields (1984) is a good start.

But "The Cambodian Space Project: Not Easy Rock'n'Roll" is an excellent follow up to modern day Cambodia. Cambodia is far more than the genocide.

It's an amazing country. You can fire rocket launchers, go to rocket gambling, they eat everything, it all is and isn't part of the Khmer Rouge legacy. Angkor Wat is one of the top ancient monuments in the world. The beer is cheap, you can buy cannabis pizza in the tourist district. And the people are really friendly and just do beautifully thing like sing and men hold hands, which is strange a Westerner.

Also note many on HN deny the Cambodian genocide, it doesn't fit the UN's definition they cleverly memorised. The Cambodian trials where about very small parts of the million killed. Because as per the UN/HN definition you can't call killing your own people genocide. But offering birth control does count for genocide, because modern bureaucracy around words.
Counterpoint: I got a free Amazon Echo (gen 1 echo, echo dot, echo show) for free by writing a few voice apps. Amazon has so ce cleaned up the lowest effort ones I made.

I could feel the submission process get tighter as time passed. I think the idea was to see what apps people come up with and what gains traction? Kind of like the story where the management lets people on the grass and paves a walkway on the most walked path?
It is more than that though. Let's take a kid who has a good feel for math, but make them do several pages of addition and subtraction problems every night for homework instead of teaching them that there is such a thing as "math" and what they are doing is simply "arithmetic". Run this into the ground until they get sick of the subject.

Now finally introduce some math formulas, but don't tell them what they are learning -- instead they just have to memorize these expressions without purpose. And since this kid isn't really good at anything artistic (can't even begin to draw anything recognizable because they haven't ever been taught some basic techniques), how about we have them combine the math with an art project "to make it more fun", then fail them in math because their art is sub-par, and the results makes it "obvious that they didn't even try" (not that they don't know how to do art).

Is it really hard to take a simple to understand concept such as the area of a rectangle (that the kid already understands) -- then instead of telling them that the area of a triangle is "base times height divided by two", how about drawing a box on the board, and drawing a line from corner to corner making two triangles. Now it is obvious why you take the formula for a rectangle and then divide it by two to get the area of a triangle.

Ok, lets take this one step further -- you need to figure out how many feet of siding strips are needed to fill in the peak of where a wall joins a roof. "Hey I know this, it is base times height divided by two". But then you order the materials, and you come up short, because you have waste at the ends due to overhang (so you really need to draw out your triangle with the base several inches wider [add 2x the height of your siding strips to the base]). That is where the simple schooling didn't translate to the real world simply because the kids are taught to memorize answers for a test.

Startup Idea:

Mobile app using computer vision to roughly determine BAC based on facial and optic features. No one has a breathalyzer but everyone has a phone, so people will be able to get a more objective measure of their inebriation without drunkenly doing math of how many drinks they had. If a cop can estimate it with a flashlight, a phone can too.
I mean, I'm all for anything within reason than can prevent DUI, but in my travels, cell phone use is a much, much more pervasive problem that is only poised to get worse. It makes me concerned it's flying under the radar.

I'm not attempting to straw man or anything, but curious if others feel the same way.
False and misleading headline.

The judge explicitly stated on the live stream that he did not "buy" either side's arguments that zooming was or was not a manipulation. He stated that an objection was lodged and that he needed a sworn statement in evidence, from someone other than the lawyers who were admittedly both guessing, that there was no distortion of the image. Based on the livestream he never prohibited the prosecution from doing their pinching and zooming.

Moreover if it were really as "obvious" as the prosecution claimed it was, then I can see no reason why they did not produce such a statement. Or, alternatively, why they dug their heels in so hard and insisted that they be allowed to show the evidence on an iPad, despite 100% of the substantial audiovisual evidence so far in the trial having been shown on courtroom screens. Defense lawyer was completely wrong about upscaling (possibly getting confused with gpu AI upscaling?), but I can find no fault at all with him smelling a rat.

Typical homework does not enhance learning at all. It's given out because parents think seeing their kids suffering through drills means they're learning.
My current car is pretty old, but it had a really loud buzzer that went off if you started the car without the seatbelt on.

I never drive without my seatbelt, it's just automatic for me to put it on, but I often start the car and let it warm up a bit while I rummage with my stuff on the passenger seat or whatever.

I had to buy an ELM device and hook the car to my laptop and use some dodgy Russian software to disable that stupid buzzer.

I dread buying a more recent car because it seems they're rapidly adding more and more stupid, annoying, and privacy removing anti-features that you can't disable.

What resources? It was a straightforward process for me.

Here's my experience applying for student visa from India.

Once the US university accepted me, they physically mailed me the paperwork (acceptance letter, I20/DS2019 form etc).

I scheduled an appointment (which involved filling up a huge form online that took 2 hours) with my nearest US Consulate, which was the one in Chennai. I believe (not sure) the US Consulate in Chennai is the largest consulate US has worldwide. I think this facility processes the most number of visas or something.

At my meeting with the US consular officer they examined the paperwork, and my visa was approved.

The meeting with consular officer took only 5 minutes, though I had to wait an hour to reach the front of the line. They didn't even ask me too much questions — just what my parents and siblings did.

However, I hear about a lot of people who got their student visa application rejected, so I have no idea why it was easy for me and hard for them.

And I did this twice. Once for a single semester exchange program to the US, and another when I decided to get my master's degree from USA. The visa interview was a pleasant experience both times.

Later, when my parents decided to visit the US, it was a straightforward process for them as well to get a tourist visa.

Of course, work visa is a totally different beast, I hear.

(Also — not relevant, but I returned back to India after my masters due to personal reasons. I had a really good time in America).

> homework

This is one issue that I'm passionate about. Research increasingly implies that homework is probably harmful in elementary; of dubious value in early middle school; and only valuable in high school and beyond.

> and objective performance assessments

I think some of these radical experiments are crazy. But, there's valid reasons to consider e.g. not grading missing absent assignments as a zero. A few of them:

A) If our goal is for grades to reflect demonstrated student mastery --- a missing assignment doesn't indicate that proportion of mastery "missing." Especially if it has been demonstrated satisfactorily on an exam or by other measures.

B) A couple zeroes on a gradebook can be an insurmountable hill to climb-- leaving no further grade incentive at all for students to work hard in the class.

C) Grades are strong motivation for already-strong students with the most involved parents, but can actually be demotivating for the bulk of your class. An effective teacher needs to find other ways to motivate students. For many students, grades are something that can make one feel bad about oneself but not provide an opportunity for positive differentiation.

The classes I teach are "easy A's" in the gradebook for most of my students... and are incredibly demanding compared to normal MS/HS fare. This requires buy-in from my students. I work to build genuine curiosity and in-class competition (on a variety of axes where all students can excel, not just the top couple dunking on everyone else).
I was referring to internships in general, not just at Google.
The crazy thing is that the bar is so low in the US.

Where I live, Hoboken, NJ, the high school math and reading proficiency rate are 8% and 44% respectively, while the graduation rate is >95%

What the hell are they doing if they're not even teaching kids math and reading? And why are they graduating them?

Grades aren't meant to be a feel good merit badge. They're supposed to be an accurate reflection of your level of knowledge relative to your peers. If it ceases to be that, then the selection just happens elsewhere. So now high school diploma isn't worth anything because everyone graduates. Hiring a high school graduate doesn't even guarantee you the person can read. Same thing happens in bachelors as schools become less selective and inflate grades.
Dealing with stress/anxiety/deadlines is a vital life skill. At some point people have to face failures and consequences (even if the failure was "not their fault"!) and learn to handle them; if they don't do it in school they'll be doing it for the first time in college, or in the workplace, or with governmental requirements.

> Those are some of the few companies that are large enough to oppose government

They're more likely to cooperate with governments because they have so much to lose. All the big guys are caving in to China for example because they don't want to lose that sweet 1+ billion consumer market. Yes even Google. Check maps.google.cn and see the border around the South China Sea.

And also their interests are much more aligned with the governments, being entities similar in size and controlled by huge shareholder interest groups.

Oh and finally most of them don't even pretend to oppose government interests. Even Apple.

The best thing about Matrix is that both the software and the network is open and decentralised. This is why I prefer it over Signal (which even frowns on third party clients)
Japan is very interesting for a lot of reasons.

1. An incredibly stable society which is at the same time fantastically, amazingly creative. And not just in the traditional arts, which have been wowing Europeans since they first saw Japanese woodcuts in the 19th Century, but in literature, video games, film, fashion, and modern arts as well. Just explosions of creativity with Japan represented as among the best in each area.

2. A society that very strongly values quality, responsibility, safety, nature, and beautiful spaces. I very much wish we were able to build livable cities that were as clean, human-scaled, walkable, and safe as in Japan.

3. Fascinating economy in which massive government deficit spending shows no signs of raising interest rates or inflation. Basically the opposite of what most modern economists expect, as well as the opposite of how most western nations behave. This could be in part due to the strong cultural premium on safety and security by individual households.

4. Historically, the first non-Western nation to industrialize, and to have done so relatively early along its own unique development path.

5. The best restaurants in the world, and Japanese cuisine is wildly popular.

6. Zen Buddhism is popular in the West.

7. A lot of people are fans of Japanese manufacturing and design.
