Bevy’s 4th birthday.

Its Bevy’s 4th birthday and while I’ve been around for a couple of previous birthday posts I’ve never written something myself.

This year I chose to step up into some additional maintainer duties on ecosystem crates like bevy_ecs_tilemap, which I consider foundational and important to update to new versions, and I started This Week in Bevy, which I’ll talk about a bit more later.

Why Bevy?

The overriding reason I started writing Rust in the first place is that it expanded the kinds of programs I could write. Game development falls into that category, so I started working with Bevy a number of years ago, before there were regular releases, but really ramped up when 0.8 introduced the Material APIs which really inspired me to dig deeper into rendering, and feel like this year was an

Computational Fluid Dynamics (in graphics mostly)

Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic. Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000
