Event-like hooks are changing

There are many, many hooks in MediaWiki core. Some (20%?) are event oriented. Those are changing to use an event-based architecture in Core rather than an ill-fitted hook-based architecture. Dan Kinzler gave a presentation: From Hooks to Events: evolving MediaWiki's extension interfaces - which I should probably listen to again. The event system was implemented in core back in 2015/2016

Shellbox

Shellbox https://wikitech.wikimedia.org/wiki/Shellbox is a library (GitHub mirror repo) for remote command execution, and a server for secure command execution. This means that you can do stuff like image handling or video transcoding, or Pygmetize syntax highlighting etc. without needed specific libraries, utilities, or applications installed on your web nodes. Wikimedia uses Kubernetes to run mw:Shellbox and has a Helm chart that may be reusable. There was some discussion at the conference of using it to run the job queue? I'm not sure. In any case, if you look at the Wikitech sidebar/infobox Shellbox is distinct from the JobQueue system.
