> College can't ever get cheaper.

Residential college. For most, college will look more like community college, commuter college, night school and other extension sites, or online college.

As you say, this is already underway in the US (due to the “demographic cliff” in projected high school graduates in most states).

>So if school kids are being taught "the WW2 era American internment camps should be called American concentration camps," they're actually being mislead.

Internment is for foreign nationals. The implication is there is a loyalty conflict (foreign citizenship) that requires them to be controlled. Concentration camps is the correct term.

If people are trying to gatekeep the term "concentration camp," a term that existed before WW2, they should stop.

>The lesson can't be oblivious to popular understandings or less precise popular usage.

No sane person equates the Japanese-American experience with the Holocaust so I'm not sure exactly who you think is actually trying to "lie and mislead." For decades, the vast majority of the community (led by the JACL) preferred to say nothing about it in the interest of integration.

The renaming is about stopping the use of anodyne terms ("relocation center" and "internment camp") that literally did, and do, nothing but make a few people feel better about the armed imprisonment of US citizens. Roosevelt, Truman, and several of their secretaries called them "concentration camps."

As the old saying goes: “Chemical engineers do it in packed beds”

I can’t read the second article, but the first does not cite the later work and makes exactly the same mistake as Winner: sitting at a desk, assuming that (per Caro) parkways were the only way to get there, and looking only at the parkway bridge heights. The point is that parkways were by definition not for commercial traffic and you could get there by routing around the parkway overpasses, and the contemporaneous bus schedules show that they did.

It’s worth noting that Winner's specific story about the low parkway bridges blocking bus access to Jones Beach (which he got from Robert Caro) has been debunked. Some design researchers in Canada, cued by earlier work in STS, finally dug up 1930s bus schedules to Jones Beach (east via Jericho Turnpike to Mineola, then south to Jones Beach) that simply avoided the low parkway bridges.

Surprisingly, these appear to be rigid foils (hence WindWing) instead of Flettner rotors.

Phalanx is the US CIWS based on the 20mm Vulcan gun. in other words, Phalanx is the “last line of defense machine guns” to which you are referring.

You may be thinking of Aegis, the integrated combat control system. We don’t yet know why the Gravely was unable to intercept the missile further out. Could have been human error, could have been a sea skimmer getting too close before being detected. To date, Aegis has been extremely effective against ballistic missiles and old cruise missiles. But given enough time an enemy can test your potential weak spots.

10th grade is the “on level” time to take geometry.

The “standard” place for geometry is 10th grade (after algebra 1 in 9th grade). A few geometric ideas have been moved from geometry to algebra 1 so that slope can be explained using similar triangles but this is just about memorizing explanations instead of doing proofs.

Today, if you aren’t in an honors geometry section, you likely learn a handwavy version of two-column proofs and do some pretty linear proofs that way. No symbolic logic, no mathematical writing.

There’s also an intermediate number theory class that’s basically at the level of a college elementary NT course (one that does not assume abstract algebra), an Olympiad geometry class, and a group theory class. The first two do not have a text, the third has a text but you can’t get it without enrolling.

The ones that have “instructors” and class times have chat-based sessions that you can skip if you prefer. Part of the homework is based on an adaptive problem system (Alcumus, which you can actually use for free) and part is weekly problem sets mostly based on the textbook. Writing (proof) problems are graded by a human so it is a useful way to get feedback on your proof-writing skills (if you know you are worse at it than a college math major).

> details that your interviewer is fishing for (because they learned it in their PhD)

Haha, that was my third interviewer! Some random computational geometry problem. But it worked out for me as I happened to have read Preparata & Shamos as an undergrad.

I suspect this comment under TFA is closer to what’s going on: “My sense is that winning Westinghouse has slanted substantially toward the types who just want to overachieve and go to Harvard relative to the types who are weird nerds even apart from any differences between subjects.” Access to the professional mentoring and resources needed for kids to do projects at the currently-competitive levels has literally been commodified. This underlying population change then explains why they don’t go into science careers.

Fry’s knew that single queue multiple server had lower waiting time variance before everybody else in retail did. No surprise that John Fry funded the American Institute of Mathematics!

Plot twist: it gets 25/25 on AMC 8

No idea why this came up in HN, but I remember being boggled by this while reading Randy Hyde’s book on 6502 assembly. Made the idea of p-code and such seem more mundane, later.

Yes! These kinds of initiatives are not focusing on tutoring the ”ahead” kids as some think, they are about tutoring the “behind” kids because teachers cannot possibly overcome multiple grade level differences using classroom differentiation. So as you say, the teaching example in the article is entirely missing the point.

The real question is whether you can get Bloom’s 2-sigma effect without a human tutor (for social accountability) when the student is disinterested. I think it will take more than just a chatbot to make a student feel like somebody cares whether they get it or not.

100% of large companies I’ve worked for. Any competitive lawsuit can trigger keyword-based e-discovery. The rationale is that nobody but lawyers even understands the full legal meaning and significance of those words so you shouldn’t use them except when consulting with lawyers. Similar arguments apply to IP (patent) discussions.

The US just announced that it is buying off-the-shelf anti-drone systems for Ukraine that operate chain guns in single-shot mode. Drones are slow so they can use VT rounds instead of the CIWS spray-and-track method.

I avoided his classes like the plague. His name was already a verb in the 80s.

Which is not to say that I ever held that against him personally. It was kinda cool that you’d be in Evans at 2am and he’d still be randomly wandering the halls.

I couldn’t figure out why this was here, but I guess it’s because there’s a new barrel processor design: https://news.ycombinator.com/item?id=37315802

By ABET. The institution as a whole is accredited.

The question is whether accreditation from an engineering org is worth the limits they place on your curriculum. Stanford EE and CS and Cal EECS all say no, they’d rather give their grads more flexibility than have them jump through ABET hoops.

My real analysis instructor drily pointed out “You really like proof by contradiction huh” and my defense was that my main life skill is spotting why plausible-seeming things don’t work correctly

It’s hard to defend generic standardized tests. (Whereas ASVAB is ok.)

They don't grant degrees or diplomas. As such it is presumably accredited as a Supplementary Education Program and (like JHU CTY, Stanford ULO, and AoPS) do not grant credit. Such programs can be the basis of credits if your "real" high school accepts them, though.

If you go to Venice for the Biennale, part of the exhibit space is at the Arsenale [0].

The PARC campus is part of Stanford Research Park, so no.

There’s this gap between ~$150k HH income (where the good aid disappears) and whatever you think it takes to afford $90k/year and still support the rest of your nuclear family. That gap covers a lot of the HN population so I think you can see why people here are salty when the upper end of the gap is receding so fast there’s a red-shift.

Dale & Krueger and its descendants are based on a college cohort from 1976. It reflects the college goers of the 70s (not only male-heavy but white-heavy) and economic history as it applied to the Boomer generation. My personal expectation is that the higher ed sector, by collectively shunting high-achieving middle class students to lower-tier schools because “they will have the same outcomes” according to this line of research, will turn out to have contributed to substantial downward mobility in that segment.

It's a joke, sinusoids are sums of exponentials when you're talking about complex functions [0].
