Your ECS Probably Still Sucks: Part 1 – Memory Matters

This article was first written during the Unity Fee-asco of 2023. As such, many Unity ECS community members were seeking alternative high-performance solutions, and were asking me about potential places to migrate some technology I have developed.

Unfortunately, most of the ECS solutions were inadequate for facilitating the technology, yet it hasn’t been easy to explain why. That’s why this series exists. I’ll explain several ECS concepts ideas that are often overlooked in

	-- show running queries (pre 9.2)
	SELECT procpid, age(clock_timestamp(), query_start), usename, current_query
	FROM pg_stat_activity
	WHERE current_query != '<IDLE>' AND current_query NOT ILIKE '%pg_stat_activity%'
	ORDER BY query_start desc;

	FROM pg_stat_activity
	WHERE query != '<IDLE>' AND query NOT ILIKE '%pg_stat_activity%'

	App configuration in environment variables: for and against

	For (some of these as per the 12 factor principles)

	1) they are are easy to change between deploys without changing any code

	2) unlike config files, there is little chance of them being checked
	into the code repo accidentally

	3) unlike custom config files, or other config mechanisms such as Java

	Control and Command in Apple->System Preferences->Keyboard->Modifier Keys...
	or replace @ with ^ in this file.
