Unpopular opinion: Telling young people to work-life balance is actively harmful. Your 20’s are the best time to grind. You have lots of energy and few responsibilities. a good 20’s grind creates the space to chill in your 30’s and beyond

What if software engineering paid royalties? Like $0.00001 every time your function is called 🤔

I wish more engineers thought of APIs as abstractions instead of pass-thru access to the database

Why are engineers so surprised to learn that they're meant to deliver business results bigger than their salary?
