Python Extensions with Rust and Go

The goal of a developer retreat is to stop what you are doing for awhile and explore something new. This usually requires a shift in mindset, and the biggest shift is to suspend the focus around productivity and urgency.

We Haven't Invented Zero Yet

I am the author, with Svetlana Isakova, of Atomic Kotlin. I suspect most people currently alive were introduced to the concept of zero quite early in their development—early enough that they internalized it as a foundational principle and don’t ask questions about it. In addition, many people probably know that zero was invented after the original number systems. The ancient Greeks didn’t have a zero, and it puzzled them: “How can nothing be something?

I couldn’t quite put my finger on what bothered me about these design ideas. Then @codingunicorn did it for me by writing a post called Flexible code considered harmful.

Developer Retreats Keep Getting Better

The recent developer retreat took place August 20-26th. We arranged it because my friend Luciano Ramalho (Thoughtworker and author of the best-selling Fluent Python) was doing a multi-stop trip to the US (from his native Brazil) and had a gap in his schedule, so he wanted to come to Crested Butte and have a retreat. This seems to have become a pattern: someone I know would like to come here, and we end up organizing a retreat around their trip.
