I have just pushed a translation of my 2018 article on transducers on our @activegroupgmbh.bsky.social company blog. In it, I dissect the how and why of Clojures transducers. Would love to hear your feedback! 🤩 funktionale-programmierung.de/en/2018/03/2... #clojure #functionalprogramming #lisp

Kollege @defmarco.bsky.social hat's schon perfekt zusammengefasst: der Blogartikel lohnt sich (und ist mittlerweile auch in englischer Sprache verfügbar, nämlich hier: funktionale-programmierung.de/en/2025/10/1... )

Tickets for @bobkonf.bsky.social are on sale now! If you're interested in functional programming or anything that should be more mainstream, this is the place to be! @activegroupgmbh.bsky.social would love to welcome you there! bobkonf.de/2026/registr...

I still like Bluesky, but posting was never really my thing. Recently I've been giving the Fediverse a shot and it feels much more cozy! I'll keep trying it out, just posting random stuff (editor things and #crossstitch mostly atm). Updated my bio and happy to find familiar avatars over there!

You have one more month to submit a talk or tutorial proposal to #BOBkonf2026: the deadline is 17 November 2025. We look forward to hearing from you!

We sat down with Stefan Wehr, professor at the Offenburg University of Applied Sciences, who has extensive experience with Haskell both in academia and industrial application. Enjoy the episode! haskell.foundation/podcast/71/

Der Kollege Schlegel hat ein paar kluge Gedanken zum Thema "Testbarkeit von puren Funktionen" und das Verhältnis von "testbar" und "formalisierbar" aufgeschrieben. Kurz und lesenswert auf unserem @activegroupgmbh.bsky.social Firmenblog funktionale-programmierung.de/2025/10/13/t...

We're back! Mark your calendars: BOBkonf returns on 13 March 2026 … … and our Call for Contributions is up, with a submission deadline of 17 Nov 2025. Find out more here: bobkonf.de/2026/cfc.html

If the money spent on AI edtech could go toward schools instead, it would make education more accessible to all children, critics argue. “But it’s not sexy to say, ‘We need more teachers.’ It’s not sexy to say, ‘Hey, we need better buildings.’ What is sexy and exciting are these ‘amazing’ tools”

“RAISE HELL!” ✊ Maria Bustillos (@mariabustillos.bsky.social) calls on writers & readers to defend libraries & demand ebook ownership, not rentals. Attacks on libraries are attacks on knowledge itself. 📚 Full video ➡️ youtu.be/lu8jK_27vF0 #LibraryAdvocacy #DigitalRights #InternetArchive
