Outcome-Oriented Programming

Mike McNeil, Aug 2014

Humans are not very good at planning. We have no problem running scenarios, thinking through possibilities, and pondering "what if?" questions. I might plan to not eat my cousin's birthday cake before she gets home, for instance. If I'm very serious, I might write down my commitment; or if I'm unsure about the pros and cons, use some organizational tool like a T-chart.

But when it comes to making a decision in the moment, all bets are off. The cake is a goner.

Predictive Analysis vs. Process Design

Below, I've included a figure containing a decision tree diagram.

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
