* Configurable controls would be nice. Most (modern serious) Tetris players would be more used to Z/X for left/right rotate and Shift or C for hold. (Don't listen to the people who want only one rotate button; two are essential nowadays.)
* Ghost piece would be nice as well (I think someone mentioned it elsewhere). Even grid lines would help.
* Pause doesn't work, at least on desktop.
* Line counter is missing.
* The title mentions a version 0.7. Is there a corresponding changelog?
The Chinese calendar is defined (since 1644) based on the days of true new moons and solar terms (corresponding to 15-degree solar longitudes), which also makes it purely astronomically defined.
The various Indian calendars are mostly defined using traditional astronomical texts, but I think there have been occasional attempts to update them to modern astronomical knowledge.
I'm not sure where the rate 0.003% of a day per year comes from in your comment; even the error in the Gregorian calendar is longer than this (if measured based on the northern equinox, about 12 seconds; if measured based on the mean tropical year, about 27 seconds).
Regardless, ISO 8601 has generally discouraged using spaces within expressions. From ISO 8601:2004, section 3.4.1:
> Unless explicitly allowed by this International Standard the character "space" shall not be used in the representations.
Similarly, from ISO 8601:2019-1, section 3.2.1:
> The character "space" shall not be used in the expressions.
However, through looser interpretation of the standard, "2021-10-24 11:02:03Z" could be allowed if treated as a date representation followed by a space followed by a time representation (note that the formal time representation in ISO 8601:2019-1 is T11:02:03Z, but it allows omission of T for extended format as per 5.3.5).
Running this on CJK text is an interesting exercise.
I'm not able to look at the Ganzflicker at the moment but I did skim the research study in question (given that the focus on the article is on the conjectured mechanisms and not the results themselves) and the results found there are somewhat intriguing.
Not only does it keep reasonable pace with original youtube-dl, it also incorporates several improvements from forks (detailed on the page).
The calendar reform was officially announced on the 9th day of the 11th month of Meiji 5, or 9 December 1872, to take effect 1 January 1873. This understandably caught people off guard, especially since official calendar makers had already started selling calendars for the new year a month earlier.
Unfortunately their profile [1] is gone, and the Internet Archive doesn't seem to have saved the post [2] either. Nevertheless, we've looped back to neural networks again.
Similarly a Virtual YouTuber is just an animated model driven by motion-capture software, with the motions and voice provided by a human. I doubt this is what Kurzweil had in mind.
At any rate, it's known that BB(18) is larger than Graham's number [2]. In fact, the same person has a bunch of long-lasting Turing machines for values around 18 [3], giving the lower bounds:
BB(15) > f_omega(2046) > 2046 (2046 up arrows) 2046
BB(16) > f_omega(f_omega(5))
BB(17) > f_(omega+1)(10) BB(18) > f_(omega+1)(7e57) > Graham's number
BB(19) > f_(omega+1)^3(9) > f_(omega+2)(3)
BB(20) > f_(omega+1)^4(7e57) > f_(omega+2)(4)
BB(21) > f_(omega+2)(f_(omega+1)^2(4))
BB(22) > f_(omega+2)^3(f_(omega+1)^2(4))
And for larger values again [2]:
BB(38) > f_(omega2)(167)
BB(64) > f_(omega^2)(4098)
BB(85) > f_(epsilon_0)(1907)
Of course, we expect the Busy Beaver function to grow a lot faster than these bounds.

As for the Internet Archive itself, they recently set up their Internet Arcade: Turbo Edition [1], a collection of arcade games from the 90s and early 00s that cover the most demanding emulated games playable in the browser on the site (apart from Dottori-kun, of course).

* Sidereal time is different from solar time; sidereal time measures the Earth's rotation relative to the stars, while solar time measures it relative to the Sun, which moves relative to the stars. Thus, UT1 and sidereal time have different rates.
* Wikipedia's page on day length fluctuations (https://en.wikipedia.org/wiki/Day_length_fluctuations) has a discussion of the influences involved. It also has a handy graph, from which we can see that the average day length is around 2 milliseconds shorter than in the 1970s (hence why we had a leap second every year from 1973-1979, but the last leap second was over four years ago).
* There's also UT2 and UT0. UT2 has a corrections for seasonal variations, while UT0 is derived from raw observations, without correcting for polar motion like UT1. These are rarely used.
