Thank you for looking it up! My personal hunch is that COVID related disruption in schooling is responsible for most of the within-group drop, and the rest is mostly a result of changes in educational policy, where many places deemphasize o

US has excellent education by the standard, commonly used international measures. In PISA, for example, white American children score better than any European country, and are only outscored by a handful of East Asian countries. These are a

Did the test collect any data on the demographics of the takers, so that we can check whether the drop is within-group, or whether it’s just artifact of changing composition? For all we know, this might be just a case of Simpson paradox, wh

Palantir senior leadership had not so much moved to Anduril, as it had been founded by them. Three other Anduril cofounders are from Palantir.

Everything is constant time is your precision is limited. Even the naive, recursive algorithm on integers is constant time if your integer size is limited (it will just be an exponentially big constant). To be able to meaningfully talk abou

You totally can. Here is a O(log n) implementation of the Binet formula with infinite precision: https://github.com/xyzzyz/FibBinet/blob/master/FibBinet.hs

Exponentiation is not a constant time operation, and floating points have finite precision.

You’re exactly right, I omitted the Schonhage Strassen just to simplify the point.

You cannot do Fibonacci in O(1). You can reasonably do it in O(log n), though. Recursive Fibonacci is not O(n^2) either, it’s exponential.

Yes, the collapse has happened, but it had not happened due to "privatization" of government shipyard. These were all privately owned shipyard that collapsed. The comment you are responding to is inventing some kind of alternative

Sorry, what are you talking about? None of this is true. Government-owned shipyards were not historically responsible for significant fraction of delivered tonnage. In fact, given the utter atrophy of private shipbuilding industry in US tod

Yes, but repeals of very actively enforced law that's over 100 years old do not happen every day.

They already are not built in the US at all. This is already true today. We already build less than one oceangoing Jones Act compliant ship a year. The US shipbuilding industry can hardly get any worse than it already is today.

There is also another reason, which is that passenger rail makes sense only in specific geographic and economic circumstances, and outside of Northeastern corridor, these are very few. Commuter rail requires urban population densities that

The rest of the world was in total shambles until 1960s. Europe was destroyed by two world wars. East Asia was an economic backwaters. Same was true about most of South America, and its advanced regions were underpopulated compared to US. A

What you’re missing is that our ability to move stuff around has already deteriorated to almost nil, precisely due to Jones Act and shipbuilding workforce unionization. We already cannot build vessels we need at quantities we need. This is

My claims are supported by the arguments made by the prosecution in all instances of the appellate court, the arguments that jury and the appellate courts found convincing. Even the dissenting SCOTUS justices would not argue that the guy ac

They have always been such.

What’s the value of me doing that, when the case has been prosecuted and was argued in all instances of appellate court literally to death? You can read court opinions, they are plentiful in information, and do not suffer from elementary lo

No, but they have ability to influence procedural outcomes. This is the whole purpose of the so-called “Innocence Project”. They very much attempt to free convicted murderers, and often enough they succeed at this task.

No, a prosecutor at no point argued that this guy was not guilty. Nobody argued that, except dishonest activists who lied to you. All prosecutor offered was commuting the death penalty to life without parole. In addition, I don’t see how a

Finding intersection points of a circle with a line is equivalent to solving a system of equations, where one equation is that of a circle, (x-a)^2 + (y-b)^2 = r^2, and the second is that of a line, Ax + By = C. To solve it, you’ll be takin
