Yesterday I did a small presentation on some awesome ruby tricks and tools, touching a bit on

why and when to use keyword arguments
splat and double splat
rspec’s verified doubles
rspec --bisect and random spec ordering
pry
ruby 2.3 dig and safe navigation
ruby threading and implementations

as part of talkdesk’s TGIF engineering presentations.

Nothing groundbreaking, but still interesting, I’d say ;)

You can find the slides below:
