A lot of “data usability” comes down to pretty unglamorous work: cleaning, standardizing, reconciling edge cases - but that’s the part that makes everything else possible.

Excited to be speaking at Good Tech Summit in DC April 7 www.goodtechtogether.org/summit
We’ll share a program focused on K-12 education and talk about investing in the foundations of AI: data, models, and benchmarks. We'll explore how these shape AI development in a field. Join us!

Super interesting work on new proposed columnar data file format called F3 with embedded wasm binary to decode the data 🤯 (which obviates the need for 3rd party library support). Favorable comparisons on compression, throughput and random reads to existing formats.

Interesting to see empirical research coming out for LLMs as education aids. In this study, active use of LLMs helped CS students debug compiler errors. Removing LLM access demonstrated no lasting learning benefit from having had access to it...

Thought I would spot check a application someone was posting about 100% vibecoding. Can you spot the issue?
Kudos to the LLM, this is verbatim from the fastapi docs. Sometimes verbatim from the docs is not what you want for your application though....

Interesting announcement on a product from Astral! Similar model to one of the core @anacondainc.bsky.social lines of business.
Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry.
We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

How are people managing code review for their AI coding agents? I do a first glance and it is obviously bad (e.g., didn't refactor repeated code), and now I've got half a dozen AI diffs for things that aren't good enough cluttering up my todo list with things to respond to....
