flatbush VS liwords

> (There are ECS frameworks in JavaScript, which gives you absolutely no control over memory layout and thus completely defeats one of the primary purposes of the pattern.)

While JS does not provide great support for bit packing complex structs, typed arrays give you quite a bit of control over memory layout for simple numeric types, which is what you usually want for optimal data-oriented code anyway. This is a common technique used in fast JS libs for data visualization, ie:

https://github.com/mourner/flatbush

There are also basic operators required for bitarrays, which are useful for ECS and memory-efficient code generally.

using flatbush library instead of rbush which optimise the statically placed element, from the benchmark in the repository it could boost up to 5x the performance of rbush.

But for 500 k points, it's not many. I'd put it in the database tech I was using and hit an API for it. Or like you say, load it into memory and use Mourner's flatbush for a super simple and super fast solution..

> At pbf speeds, decoding is usually no longer a bottleneck, but bandwidth might be when comparing with gzipped JSON.

we were streaming a few hundred datapoints in a dozen flat arrays over websocket at 20-40hz and needed to decode the payload eagerly. plain JSON was a multi-factor speedup over pbf for this case. but it's fully possible i was holding it wrong, too!

even if your "bottleneck" is rendering/rasterization (10ms), but your data pipe takes 5ms instead of 1ms, it's a real effect on framerate, battery, thermals, etc.

i'm a big fan of your work! while i have you here, would you mind reviewing this sometime soon? ;)

Check out https://woogles.io (disclaimer I am a cofounder). AGPLV3 platform with world class bots, puzzles, a free analyzer, clubs/tournaments, and more to come. You can see the source code at https://github.com/woogles-io/liwords. We recently hit 5M games played and have hosted a few major tournaments.

A small team of us work on a project https://github.com/domino14/liwords - this is an online crossword-board-game playing website. We have around 6000 MAU, are fully free and open-source, and need a lot of coding help!

We built woogles.io (a crossword board game playing site with almost 10K MAU) in Go. See https://github.com/domino14/liwords

https://github.com/domino14/liwords - warning it’s not that well-developed but it’s ok

A small team and I made https://woogles.io - we were inspired by lichess to make a site to play crossword board games during the pandemic (like Scrabble, Words with Friends, etc).

We did raise money on Kickstarter - 25K but are purely donations-driven and open source (AGPL3) Most months we just get enough to cover the cost of running the servers. We have around 6000 monthly active users, have hosted several big worldwide championships, have puzzles, and just earlier today released a board editor / broadcast mode for annotating real life games in real time. We also have a top notch bot AI and WASM-based analyzer.

Our stack is Go, Typescript + React, with NATS/PGSQL on the backend.

woogles.io

The people behind those websites and apps have no clue this software exists. The exception is woogles.io because it is associated with the Macondo AI. /u/14domino is the brain behind both of those things

https://woogles.io raised $25K on Kickstarter and built a more beautiful site. Come join us (we’re still taking donations :)

- Playing online: there is woogles.io which I personally would recommend; it's made by players for players and is free to use. Among the features are: play against humans, play against strong bots, tournaments, feedback on your moves after the game, availability of different languages and game variants. Other options are: playscrab.com (also made by players for players); isc.ro (the Internet Scrabble Club); the app Scrabble Go and, if you don't mind playing with slightly altered game rules, Wordfeud, which comes along with a large online league (not technically affiliated with the app itself).
