The actual Ruby for Good website has more information: https://rubyforgood.org/
Why does Ruby still have this artisinal aura to it, never seen C/C++ For Good gathering.
I volunteered a few years ago and had a great experience.
The only programming language I know of that is obsessed with trumpeting its own moral virtue. "Matz is nice so we are nice," "Ruby for good," dragging DHH, etc.
Meanwhile the Ruby Central and whytheluckystiff debacles show it to be anything but.
I’m glad to see conferences like this exist. It creates dedicated space for these focuses and the people who care passionately about them.
