Aside: Practical concerns about running a program beyond the end of the universe are outside the scope of this article.

Представьте: вы открываете чердак и находите пыльный ZX Spectrum. «Музейный экспонат», — думаете вы. А что если я скажу, что эта коробка с 48 килобайтами памяти может с 95.5% точностью распознавать рукописные цифры и проходить те самые CAPTCHA-тесты «Я не робот» из 2010-х?

Более того: технически она могла это делать с момента выпуска в 1982 году. Мы просто не знали правильный алгоритм 43 года.

<...> I decided someone needed to try to create a Postgres configuration optimized to process queries as slowly as possible. Why? I am not sure, <...>

I can’t make this too easy. This is a Postgres tuning challenge, not a throttle-your-CPU-to-one-megahertz-and-delete-indexes challenge, so all changes must be on parameters in postgresql.conf. Additionally, the database will still need to have the capability to process at least one transaction within a reasonable amount of time—it would be too simple just to grind Postgres to a halt.

I have created a crate called fibonacci-numbers. There are 187 different major versions of the crate, each exporting the Fibonacci number corresponding to that version.
<...>
Version 186 depends on version 184 and 185 and exports the largest Fibonacci number that fits in a u128:

pub const VALUE: u128 = fib184::VALUE + fib185::VALUE;

esotoric [sic!] programming language that's read like a spellbook
