⚡️ Lightning: Mapping the International PyData Community featuring Web Scraping and Data Wrangling - @hevansdev.bsky.social Hugh loves maps! But Meetup’s map of PyData events is not great. So he made a better one: circle size for group and green for newly scheduled meet-ups.

PyData London @pydatalondon.bsky.social · 02/12/2025

Lightning talk: Amusingly Abliterated LLMs - Ian Ozsvald Even if you ask it to be rude, LLMs will tell derivative dad jokes. Can we make an LLM tell good jokes if we remove the guardrails? It’s definitely rude, but also more original.

120

PyData London @pydatalondon.bsky.social · 02/12/2025

Our first talk is Productionising research papers with Python and serverless infrastructure - Chess commentary generation use case @guillaumealla.in

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!

010

PyData London @pydatalondon.bsky.social · 04/11/2025

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!

031

PyData London @pydatalondon.bsky.social · 07/10/2025

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!

021

PyData London @pydatalondon.bsky.social · 07/10/2025

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.

Finally tonight our second lighting talk: The future of Python Notebooks - Rahul Ayyappan Notebooks are ubiquitous but have limitations like hidden state (which cells have we run???). We can improve on this with new tools like Marimo.

020

PyData London @pydatalondon.bsky.social · 05/08/2025

Next up tonight is Yash Sakhuja with Fuzzy, Not Fussy: Using AI to Tackle Data Entity Resolution at Scale Messy customer data — typos, inconsistent formats, and duplicates — can make it surprisingly difficult to answer basic questions, such as “How many unique customers do we have?”

110

PyData London @pydatalondon.bsky.social · 05/08/2025

Our first talk tonight is from @datancoff.ee on How to prepare your AI Agents for the Ice(berg) Age. LLMs are extremely powerful, but their data is often old and they hallucinate. We can largely solve that using agents with tools.

Now up Code Reviewing ChatGPT by Peter Bleackley Pete tries vibe coding the Viterbi algorithm with (at best) mixed results. But LLMs are much better at producing routine code. Creative coding is still a challenge.
