I'm going to get along to the sysadmin miniconf at linux.conf.au online 2021 to see if I can upskill a bit https://lca2021.linux.org.au
Lots of interesting sounding sessions and there's financial assistance available for those that need it: https://lca2021.linux.org.au/news/financial-assistance/ Thanks @hugh and others for posting about the conference - I wouldn't have known otherwise!
