That's one of the rabbit holes I went down for edition #55, Is the Sun Deciding How You Feel?, which went out this Sunday

Rjukan sits so deep in a valley that it receives no direct sunlight for six months a year. In 2013, it installed three giant computer-controlled mirrors on the mountainside to redirect sunlight onto the town square. Considering that sunlight sets our serotonin levels, regulates our sleep, shapes how we make decisions, and even registers as a physical sensation in our joints before a storm arrives, we can easily say that Rjukan had a solution-oriented mindset.

That's one of the things I went down a rabbit hole on for Edition #53, which went out this Sunday, to celebrate last week's World Poetry Day

Diana Ferrus was studying in the Netherlands when she wrote a poem about Sarah Baartman, a South African woman whose remains had been held in Paris for nearly two centuries. The poem became so powerful it was eventually incorporated into French law and helped bring Baartman home.

The news dropped yesterday: OpenAI is shutting down Sora, their AI video app, six months after launch. The Disney $1B deal is off, and the API is going away, too.

The arc is fascinating if you zoom out. The app launched in September 2025, hit the top of the App Store within a day, and reached 1M downloads faster than ChatGPT did. By January, downloads had dropped 45%, and the whole thing had made roughly $2.1M in in-app purchases over its lifetime.
