interesting. does your book cover geohashing. I've been curious how points and polygons get converted to geohashes and how the search using these work. I currently postgis as a black box but I haven't been able to find any books or articles that really explain in depth how they work.

There's a great blog written by someone who wrote a very efficient geohashing algorithm in go/assembly that may help a little bit with understanding it. https://mmcloughlin.com/posts/geohash-assembly The simplified TLDR is: 1. Convert lat and long to something that's represented by bits. 2. Interleave these bits such that lat and long bits alternate in the sequence. 3. Optionally, but seems to be the standard, encode…

thanks for the link. I would pay good money for a book that explains in plain english and a few go/python examples how these are implemented and the theory behind them.

I've played Overcooked 1 and 2 with my girlfriend, just played the Plate Up demo with her, and I think you're right. Mario and Sonic games prob look the same to ol' gramps up there, too. Overcooked has specific arcade levels each with their own infuriating gimmick. You either can beat it or you cant. Plate Up, despite having similar mechanics (place food onto stove to cook it), is quite different. You have to take or…

Plateup at the top level is a simple cooking and upgrading your kitchen game. It can also quickly turn into a Factorio-type game once you start automating the cooking of the food. Which sounds boring, if all you’re doing is serving, but it then turns into a game almost similar to Guitar Hero once you get into the overtime rounds because you’re having to put into muscle memory all of your actions with higher intensity…

Add to that interactivity with Twitch stream viewers who can visit and order and even pay with tangible money, adding another twist and a layer of appeal to viewers and especially streamers. That fundamentally changes the game IMO, turning a game to play with friends into a game to stream and participate in.

My first self-published book sold maybe half a dozen copies, and there even was one refund. The reason is simple. It is a bad book. The next one sold none. Which is expected since I made it openly available from my site. It hit about half a million downloads in the first year. Alas, most of them were from one IP somewhere in Czechia so I guess someone's spider got stuck in the web. But real people downloaded it too,…

S2 has a good amount of documentation about it.
