Self Hosted object storage looks neat!

For this project, where you have 120GB of customer data, and thirty requests a second for ~8k objects (0.25MB/s object reads), you’d seem to be able to 100x the throughput vertically scaling on one machine with a file system and an SSD and never thinking about object storage. Would love to see why the complexity

The real world success they report reminds me of Simon Willison’s Red Green TDD: https://simonwillison.net/guides/agentic-engineering-pattern...

> Instead of taking a stab in the dark, Leanstral rolled up its sleeves. It successfully built test code to recreate the failing environment and diagnosed the underlying issue with definitional equality. The model correctly identified that because def creates a rigid definition requiring explicit unfolding, it was actively blocking the rw tactic from seeing the underlying structure it needed to match.

It’s named after the multi-decade data compression test image https://en.wikipedia.org/wiki/Lenna

I'm using Sonnet with 1M Context Window at work, just stuffing everything in a window (it works fine for now), and I'm hoping to investigate Recursive Language Models with DSPy when I'm using local models with Ollama

The New York Times has said that the US president has reported capturing the president of Venezuela https://www.nytimes.com/live/2026/01/03/world/trump-united-s...

Source about aviation: primary (I am at an airport now) and also there are no flights going into or out of JFK right now https://www.jfkairport.com/flight-tracker?view=VIEW_DEPARTUR...

This is super interesting!

Apache Arrow is trying to do something similar, using Flatbuffer to serialize with zero-copy and zero-parse semantics, and an index structure built on top of that.

Would love to see comparisons with Arrow

My threshold for “does not need to be smaller” is “can this run on a Raspberry Pi”. This is a helpful benchmark for maximum likely useful optimization.

A Pi has 4 cores and 16GB of memory these days, so, running Qwen3 4B on a pi is pretty comfortable: https://leebutterman.com/2025/11/01/prompt-optimization-on-a...

Curious about comparisons with Apache Arrow, which uses flatbuffers to avoid memory copying during deserialization, which is well supported by the Pandas ecosystem, and which allows users to serialize arrays as lists of numbers that have hardware support from a GPU (int8-64, float)

fast.ai (some of the authors of this) was transformative for me, and the community was super nice. Cannot recommend looking into this highly enough.

This is halfbakery! I love it!

(For example, a recent half baked idea there is a perpetually burning flag. https://www.halfbakery.com/idea/Perpetually_20Burning_20Flag... )
