9. Connecticut and the 1 Kilometer Effect (alearningaday.blog)

In 2015, two geographers noticed solar panels popping up on houses in their small US state of Connecticut. Curious, they set out to see if they could figure out what predicted who had them. Would t…

11. A Preview of Coalton 0.2 (coalton-lang.github.io)

By Robert Smith
Coalton is a statically typed functional programming language that lives inside Common Lisp. It has had an exciting few years. It is being used for industrial purposes, being put to its limits as a production language to build good, reliable, efficient, and robust products. Happily, with Coalton, many products shipped with tremendous success. But as we built these products, we noticed gaps in the language. As such, we’re setting the stage for the next tranche of Coalton work, and we’re going to preview some of these improvements here, including how Coalton can prove $\sqrt{2+\sqrt{3}} = \sqrt{2}(\sqrt{3}+1)/2$ exactly.

I instrumented a FastAPI app and measured where time actually goes. Network is 69-83% of what users experience. Framework overhead is 0.2-0.8%. Your framework choice doesn

23. Show HN: Local Document Parsing for Agents (www.llamaindex.ai)

The core processing engine behind LlamaParse is now open source. LiteParse runs entirely locally, has zero Python dependencies, and is built around how agents actually iterate on documents: parse text fast, fall back to screenshots when you need visual reasoning.

27. Successes and Breakdowns in Everyday Non-Display Smart Glasses Use (arxiv.org)

Non-Display Smart Glasses hold the potential to support everyday activities by combining continuous environmental sensing with voice-only interaction powered by large language models (LLMs). Understanding how conversational successes and breakdowns arise in everyday contexts can better inform the design of future voice-only interfaces. To investigate this, we conducted a month-long collaborative autoethnography (n=2) to identify patterns of successes and breakdowns when using such devices. We then compare these patterns with prior findings on voice-only interactions to highlight the unique affordances and opportunities offered by non-display smart glasses.
