Updates

In September I visited Heart of Clojure where Christian, Teodor and I did a workshop on babashka. The first workshop was soon fully booked so we even did a second one and had a lot of fun doing so. It was so good to see familiar Clojure faces in real life again. Thanks Arne and Gaiwan team for organizing this amazing conference.

Although I didn't make it to the USA for the Clojure conj in October, Alex Miller did invite me to appear towards the end of his closing talk when he mentioned that 90% of survey respondents used babashka.

If you are interested in a full stack web framework with babashka and squint, check out borkweb.
