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.

This page points to my general interests and other homes across the internet.

📓 Creating
Spaced Repetition App

I'm building a mobile app, for iOS and Android. The app will be a form of spaced-repetition, targeting students, scholars, and anyone else interested in remembering and connecting facts. A bunch of technologies are involves. Primarily, it's React Native (with TypeScript) for the mobile app itself, and a combination of Ruby and Google Firebase for the server back-end.

🖊 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, producing a series of blog posts.

📓 Living

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. This year, I intended to visit many more. I've started to create photo albums of these experiences.


I quite enjoy taking photographs when traveling and when I'm birding. I usually suffer from vemödalen, the "frustration of photographing something amazing when thousands of identical photos already exist." I sometimes get over it, and these are the results.
