after all the attention for duckdb's acquisition by AWS: one of my favorite things is their "why @duckdb.org" page — duckdb.org/why_duckdb explainining their tradeoffs and goals; and how they try to achieve those through technical means

"Float Bloat: vector serialization gone wrong" by storing float64 instead of float32. it's a surprising problem but with elasticsearch you're in luck: * since 9.2 (index creation) `index.mapping.exclude_source_vectors` is on by default — you don't store the floats in source at all any more 1/3

hacking a tablet that was EOLed by amazon: "American frontier models won’t help and Chinese will, but not without reasoning about whether they should" the barrier is to pick the right model, say "keep going" over and over, and paying the token costs: ericpardee.github.io/fire-hd-owne...

Amazon kept shutting down my tablet, so I spent $266 on four AI models to own it
