I'm Jon. I enjoy travel, food, people, wildlife, creating things, and learning.

I'm happiest when combining many of these things: eating with friends in a new place, discussing interesting topics.

In a previous life, I worked at O'Reilly Media, BEA Systems, Salesforce and Heroku.

Today, I work for TimeToTime.app.

📓 Creating
TimeToTime.app

TimeToTime is for learning history. It provides a way to optimally remember the dates of events, as well as their context, and the relationships between them. I lead the project.

🖊 Writing
Belief / Human Behaviour

We all believe different things about the world, and come to understand "truth" differently. I started out by trying to understand "why some folk are religious", but it seems to have broadened into researching "how we believe" instead. I'm currently researching this topic.

📓 Living
Travel

I've visited over 50 cities in the past three years, mostly in Europe, North America and Africa. Sometimes it's to see a place, eat the food and meet the people, and sometimes it's to go birding.
