Ruby Sees the World.
Place a credit card in a photo. Ruby finds it, calibrates the scale, and measures everything else in the frame.

Full article with code and Jupyter notebook below.

Hey WNB.rb fam! 👋
Our July meetup is going to be GREAT!
✨ Emily Samp (Engineering Manager @ Shopify + WNB.rb organizer) is sharing insights on how type checking is revolutionizing Ruby developer tools!
🤔 Still skeptical about type checking? Perfect! This talk is specifically for you. Emily will show us why the entire Ruby community should be excited about what's coming.
Join our inclusive, loving community for an afternoon (or morning or evening, you do your timezone!)
