Intro

The below is a breakdown / bird's eye view of how a sparse-array backed ECS like EnTT or Shipyard works.

Please see the thanks and references at the bottom - without their help I would not have been able to share this breakdown with you... everything here is really just notes and rephrasing of what they've written already :)

Also, these notes do not cover archetype systems (like unity) nor adaptations of archetypes (like in Flecs). Though there's a couple comparative footnotes at the end.

Here we go!

; Standard taunts.
; 33 - Stop slinging resources. If slinging is requested early and is immediately canceled it may mess up the strategy.

1. Separation of immutable and mutable logic

Quite a lot of different people have been on the same trail of thought. Gary Bernhardt's formulation of a "functional core, imperative shell" seems to be the most voiced.

"Boundaries" - Gary Bernhardt

"Imperative shell" that wraps and uses your "functional core".. The result of this is that the shell has fewer paths, but more dependencies. The core contains no dependencies, but encapsulates the different logic paths. So we’re encapsulating dependencies on one side, and business logic on the other side. Or put another way, the way to figure out the separation is by doing as much as you can without mutation, and then encapsulating the mutation separately. Functional core — Many fast unit tests. Imperative shell — Few integration tests

Firefox bullshit removal

Due to the incessant swarm of complete and utter nonsense that has been forcing its way into Firefox over time, I've decided to start collecting my personal list of “must-have” about:config tweaks required to turn Firefox into a functional brower.

NOTE: Unfortunately this is somewhat out of date. The comments link to some resources that may be more up-to-date. Patches welcome.

These can be used for nefarious purposes and to bypass access restrictions.

Rough Notes about CQRS and ES

Once upon a time…

I once took notes (almost sentence by sentence with not much editing) about the architectural design concepts - Command and Query Responsibility Segregation (CQRS) and Event Sourcing (ES) - from a presentation of Greg Young and published it as a gist (with the times when a given sentence was heard).

I then found other summaries of the talk and the gist has since been growing up. See the revisions to know the changes and where they came from (aka the sources).

It seems inevitable to throw Domain Driven Design (DDD) in to the mix.
