Fairy-Stockfish is a fork used by LiChess for the variants on the site, but it can now play a multitude of games from Xiangqi (Chinese Chess) to Shogi (Japanese Chess) to a crazy modern variants. There's a variety of tools to train new neural nets for these variants, generate opening books, puzzles, etc. You can play some of them on PyChess (pychess.org). These are projects basically run by a couple people with huge backlogs of bugs and feature requests. An enthusiastic developer can easily get involved! Or just enjoy playing different variants and getting involved with the player community.

MNRAS is one of the three "main" journals for astronomy along with Astronomy and Astrophysics (A&A) and the Astrophysical Journal (ApJ and AJ). A&A is mainly Europe and ApJ is more mixed but with more North America. Along with Nature and Science for high-impact things and regional journals for Japan, Australia, and the US (PASP).

In this variant of Klopodavka, players can add a bug or squish an opponent's along cells adjacent to a path of friendly cells connected to the player's base. Players get six actions per turn and a player loses when no more valid moves are available. Although the AI is limited, it's an interesting game of territory and thinking about how one's own bugs will be used against oneself.

The code can be found at https://github.com/ptupitsyn/klopodavka-rs and was developed by Pavel Tupitsyn, who is also the maintainer of Apache Ignite according to his GitHub bio.

What cursive does appear to be useful for historically is writing for long periods without tiring. Cursive written in the older Spencerian script fashion is written with big movements of the wrist and arm along the main diagonal path with little finger movement. The wrist and arms tire less quickly than fingers. Some professions in the 1800s like had to write all day, so it was quite useful and worth the significant training costs of learning such penmanship skills. They also had to write with pens that didn't write equally well in all directions.

And of course other fancy scripts likely just signalled class status similar to being able to recite Homer (in Greek) on command.

I'm using Julia for a project right now, and answers are almost always found in either the Julia Discourse forum or Stack Overflow. By just searching either of those directly (plus more carefully reading the official documentation) I have found what I'm looking for much more easily.

The situation is more difficult with Python because the community aspect is more dispersed. But because my questions almost always have to do with using the standard library of external libraries, I've found devdocs.io to the be much simpler and more direct, especially because it runs offline. It covers >90% of cases for me with the docs for numpy, scipy, matplotlib, pandas, and base Python.

Maybe SEO spam forcing us back to RTFM will actually be a force for good?

For the night sky and astronomy the externality is not so great in the grand scheme, but if unmitigated it does mean that there will be fewer discoveries per taxpayer dollar sent to the NSF/NASA. I'm a postdoc in astronomy and am all aboard Starlink-style networking. But it also seems fair to me that SpaceX should be the party that's responsible for treating that externality with light pollution, or else it's the same old "privatize the gains and socialize the cleanup." We've already effectively achieved this for radio astronomy by regulating protected bands in the spectrum for passive listening.

To Western Europeans coming from the very loose state structure of feudalism, the fact that the Byzantine Empire was effectively a modern state (similar to ancient China) was practically incomprehensible to them. Hence the phrase! On the flip-side, the level of institutional capacity let the Romans and Byzantines ride out incompetent Emperors fairly well compared to feudal states that would quickly disintegrate with one bad roll of the "off-spring lottery".

People set up kiddy-pools in their room with a bit of water to get this "contextual exception" for the express purpose of streaming suggestive content. Why not just remove the exception and let people stream sexually suggestive content and make a separate category for that without a ridiculous "beaches and pools" euphemism?

Even if you live in a heavily light polluted city, you can do something astronomy-adjacent with binos: satellite hunting! HeavensAbove[1] has a really nice free android app for it. Satellites are mainly visible at dusk or dawn, and dusk is a lot easier than staying up late depending on your schedule. Plus it's like a race, they may only up for less than a couple minutes, so you have to have a keen sky-sense to pick them out. It's cool being able to know what they are too -- "huh, that's some Soviet rocket booster from the 70's"!
