Looking at the definitions section of the Wikipedia article on HSR, the Acela is around the bare minimum of several definitions, such as

Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h (124 mph).

Or

Average running speed across the corridor in excess of 150 km/h (93 mph)

The Acela is either great MSR, or about half of it is bare minimum HSR, depending on definitions.

Correction:

the first world-class high-speed rail projects in our country’s history

The US already has high speed rail: the Acela express. According to Wikipedia, though,

The maximum speed limit on the Northeast Corridor is 150 mph (240 km/h) on 49.9 miles (80.3 km) of the 457-mile (735 km) route, in four sections of track in Rhode Island, Massachusetts,[6] and New Jersey. The Acela achieves an average speed (including stops) of 90 mph (140 km/h) between Washington and New York,[3][9] and an average speed of 66 mph (106 km/h) from New York to Boston.[2][11] The average speed over the entire route is 70.3 mph (113 km/h).

That is to say, the US has HSR, but mediocre HSR.

What are some places that don't look like Linux but actually are?

I'd think most PC games and other desktop GUI software runs on windows and looks like it runs on windows. And I'd imagine that a web browser on windows isn't secretly a Linux environment.

But yeah, I've written way more code that runs on a web browser or a Linux server than runs on windows.

Sausages are also commonly inoculated with mold. The powdery coating on aged salami is Penicillium nalgiovense.

And some of the fanciest, most expensive wines are made from moldy grapes. Botrytis cinerea, when consistently wet and humid, causes "grey rot" which spoils the grapes. When it dries out, though, it becomes the "noble rot" which is prized.

Under PEMDAS, ∂2f/∂x∂y = (∂2f/∂x) * ∂y = ∂2∂y/∂x

Airbnb didn't single-handedly destroy US housing stock. It's really not even the biggest part of the problem.

Zoning codes that prevent the addition of any density to cities are way more of a problem than airbnb could dream of being. If Euclidean zoning existed 300 years ago, Manhattan would be 90% mcmansions, rather than being almost entirely low-, mid- and high-rises.

Homebrew is fairly different from pip, cargo or npm in that only python developers use pip, only rust developers use cargo, etc. And those are mostly used to manage libraries, rather than executables.

Meanwhile, essentially everyone who uses the console uses homebrew regardless of what programming languages they might or might not use. I was making a joke about how good, useful and basically required homebrew is.

Israel has been involved in several wars against multiple other nations - for example, in the 1973 Yom Kippur war, it was invaded by Egypt, Syria, and a coalition that included Saudi Arabia, Morocco, Cuba, Jordan, etc.

Israel is located at a fairly strategic location. Britain and France used Israel during the Suez crisis to stage an attack against Egypt over control of the Suez Canal. The Suez Canal is one of the most important global trade routes.

US support of Israel is a combination of funding American arms dealers and wanting Israel as a strategicly located partner. That's why we fought proxy wars with the soviet union over it like the Yom Kippur war. The aid is intended not to fight Hamas, but to keep Israel strong against e.g. Iran and other neighbors. They've had peace with Egypt for decades, but that might be more because of Israel being strong enough to not be worth attacking.

I doubt Biden personally supports the Gaza war, but a lot of this stuff is more about realpolitik and strategic concerns than anything else.

Vacant homes are any home that's not someone's primary residence when they calculate vacancies.

That includes vacation homes, temporary housing for traveling workers or college students, houses that are sold or rented but haven't been moved into yet, housing held up in divorce or estate proceedings, etc.

According to the census, last year there were 15 million vacant homes. Yes, that's a lot, and yes, many can't reasonably have a homeless person live there.

That's technically true, but really not important. Houses are defined as vacant if they're unoccupied on the day of a census. There's many reasons a house might be technically vacant, but not currently be able to house a homeless person.

Was the house just sold, and is it unoccupied for a week or a month between owners? It's vacant. Did the owner just move into hospice or a memory care unit and their children haven't yet sold the house because they need to arrange an estate sale? It's vacant. Is the house under construction but is mostly built? It's vacant. Is it not safe to live in, but not officially condemned? It's vacant.

Want to move to a city? Either you have to find the apartment of someone moving out, or you have to move into a vacant unit.

Having a good number of vacant homes is a good thing, actually; having low numbers of vacancies in an area leads to housing becoming more expensive because you can't move into a unit that isn't vacant. Increasing housing supply relative to population leads to higher vacancy rates, but decreases housing costs.

Housing-first approaches to homelessness seem to be good in practice. But those are typically done by either government-built housing or government- subsidized housing; it's mostly orthogonal to vacancy rates.

Sure, the definition of grade school doesn't really matter too much. Because college texts are written in ways that violate pemdas.

For example, if f(x,y)=x2+yx, then (∂f/∂x)y=2x+y, and (∂f/∂y)x=x. We can extend this idea to higher derivatives: ∂^2f/∂y^2 or ∂^2f/∂y∂x. The latter symbol indicates that we first differentiate f with respect to x, treating y as a constant, then differentiate the result with respect to y, treating x as a constant. The actual order of differentiation is immaterial: ∂2f/∂x∂y=∂2f/∂y∂x.

Notice: ∂^2f/∂y∂x is clearly written to mean ∂^2f/(∂y∂x).
