So /tick is now available in vanilla. Well, most of it is. Obviously only one could exist at a time, meaning /tick from carpet is gone, so here is the gist... mhm... of what happened, what is covered, what is lost and what might not be lost forever. This is not a writeup from a Mojang developer, it's a writeup from a mod developer whose part of the mod just got obsolete by a gaming studio.

The good

/tick on its own, as a query command, is moved to vanilla /tick query providing much more information about the health of the game tick. Tick performance and tick targets are also now way better handled in F3 and especially F3+2 screens, but if you are not in singleplayer or run the server with your game, a better information directly from the server through /tick query may come in handy.

/tick rate now exists as a vanilla command. It is limited on the lower end to 1 tps (not 0.1 tps like in carpet) to get a more responsive chat (the only reason so far tbh), but due to improvements to h

Arbitrary Base Conversion Algorithm

This is a function that can convert between arbitrary bases implemented in both Javascript and Python.

Many existing implementations, such as https://rot47.net/base.html or https://gist.github.com/inflammable/2929362 use a number as the internal representation, and thus can't safely encode/decode more than 8 letters of Base64 encoded text, or 9 letters of Base58 text (which isn't enough for parsing a Bitcoin address).

Other implementations rely on complicated third party libraries for bignum (e.g. https://rosettacode.org/wiki/Non-decimal_radices/Convert#JavaScript).

Several implementations required converting to Uint8Arrays (Base 256) as an intermediate. Others were essentially ports of complicated C implementations (see https://github.com/cryptocoinjs/base-x/blob/master/src/index.js).

Rust/Haskell: Higher-Kinded Types (HKT)

A higher kinded type is a concept that reifies a type constructor as an actual type.

A type constructor can be thought of in these analogies:

• like a function in the type universe
• as a type with a "hole" in it
