I gave my first ever conference talk at PyCon AU in Sept, based on my book: Escape from Tutorial Hell. It uses Swift and macOS in all its examples, but the principles apply to all languages.
I offered a 25% discount to all conference goers but not all the QR codes I distributed have been claimed, so I'm opening the offer to the next 19 people who use this link to buy: https://sarahreichelt.gumroad.com/l/iqdry/h9q4gie
