I use to write posts for Ruby Dispatch at Fly.io, so if you’re looking for Fly quality Ruby content, I publish articles about once a week at https://terminalwire.com/articles.

Coincidentally the company I started, Terminalwire, streams command-line apps from web servers, like Rails, to a thin-client installed on your users’ machines. Unlike the bananas SSH agent, I have an entitlements security mechanism that prevents servers from doing whatever in the client unless the user grants access. More on that at https://terminalwire.com/docs/client/security
