Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically. Update the cinera__*.css files 2020-05-09 20:59:36 +00:00			`[video output=day279 member=cmuratori stream_platform=twitch stream_username=handmade_hero project=code title="Finishing World Chunk Entity Storage" vod_platform=youtube id=yJjVBh7r9-s annotator=Miblo]`
Relocate riscy and add newly converted hero The idea here is to reduce the amount of superfluous stuff downloaded to each server running cinera 2017-12-06 22:26:13 +00:00			`[0:52][Blackboard: Why make an entity system using a SOA (Struct of Arrays) rather than an AOS (Array of Structs)]`
