1. And finally we have a lightning talk on USearch: The Engine Behind Most New Search & RAG Pipelines - Ash Vardanian

USearch might be the most widely used search engine you’ve never heard of, up there with FAISS and Lucene. It even supports semantic search and geospatial indexing!
November 4, 2025 at 9:26 PM
Our first lightning talk is Mise and easy: managing environments the fun way - Connor Adams. Environment management is very messy across languages. Mise can make your life much easier!
November 4, 2025 at 9:21 PM
Next tonight we’re hearing about No More Boilerplate: Data-Driven Testing Made Easy from @feregri.no
November 4, 2025 at 8:19 PM
Starting tonight’s meet up with @geirfreysson.bsky.social

Our next meetup is on Tuesday (4 November) and as ever the waiting list is building....

If you can't make it, we'd be very grateful if you could unRSVP and let someone on the waitlist take your spot.

But otherwise see you there for amazing talks and conversations!

Next up Why Python is the best language for algorithmic trading from @richardhickling.bsky.social

Now hearing from Victor Zommers on his experiments getting LLMs to play Go. They were not good, not only losing to KataGo but also Wally, developed in 1981 with just 7 rules.
October 7, 2025 at 7:03 PM
Next up we have Sam Joseph LLMs can tell jokes, but they’re pretty bad. Sam found he can breed better jokes using ideas from evolutionary computing—with pretty decent results!
October 7, 2025 at 6:57 PM
Our first talk tonight is from PyDatalondon founder @ianozsvald.bsky.social on his playgroup: a collaborative space to explore really difficult but interesting problems together like ARC AGI, diagnosing bugs agenically and making LLMs funny.
