oss updates
Dear sponsors,
It's almost Thanksgiving again. We don't have this tradition here in The Netherlands, but I do think it's a good to have a special day to count our blessings. I feel very blessed because of your ongoing support. My Clojure projects wouldn't be as well maintained and fully featured if I didn't have the sponsoring that I have currently.
You can read about the past year of OSS updates (and further back) here. Main projects are still clj-kondo, babashka, SCI, scittle, squint.
You can read about my plans for the next year here (a vote would be appreciated as well if you happen to be a CT sponsor!).
Feel free to reach out if you want to contact me about anything. Here, on Clojurians Slack, e-mail (michielborkent@gmail.com) or otherwise. I'd love to chat and catch up with you about how you are using (some of) my projects.
Here's to another year of Clojure OSS! Thanks for your support!
With gratitude,
Michiel Borkent / @borkdude

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.
