P, or NP, that is the question

This is our Twitch show 'Code & Craic' - we broadcast every Friday at 3pm CET. That's 9am in NYC and 7.30 in Mumbai. We have a look at some code and discuss some topics in 15 minute (approximately) segments. This week we talk: 1. Table Diffs; 2. P versus NP; 3. Apple Eating ads with 'privacy'.
