## Recent posts

- [Pinli is live: the work continues](https://bosnadev.com/2026/09/25/pinli-is-live-the-work-continues.md): Pinli is live. I’m sharing the product and asking for feedback on its editor, missing features, and what to improve next.
- [GPT-6 Astra can move a block almost perfectly. Precision is another matter](https://bosnadev.com/2026/09/06/gpt-6-astra-robot-precision.md): GPT-6 Astra completed 19 of 20 block-placement trials but only 2 of 20 precision insertions. Robot performance fell sharply as tolerances narrowed.
- [Will engineers forget systems that AI keeps fixing?](https://bosnadev.com/2026/09/05/would-engineers-forget-how-their-systems-work.md): Routine incidents teach engineers how their systems fail. If AI handles them, people may reach the hardest failures with less practice, and averages such as MTTR may hide that loss.
- [Spotify’s Portal cut Claude Code token use by about 90% by routing work to a cheaper model](https://bosnadev.com/2026/09/05/the-smartest-model-should-not-do-all-the-work.md): Spotify cut Claude Code token use on bulk reads by about 90% with a cheaper worker model. Most agent work needs no frontier model; its attention is scarce.
- [Elsewhere today: LLMs as a virus, Astra in code review](https://bosnadev.com/2026/09/05/elsewhere-today.md): LLM adoption modelled as an epidemic, a benchmark the models outgrew, Astra on cross-file bugs, and a lossless Vorbis and Opus recompressor.
- [Elsewhere today: Fermat in Lean, a Chrome zero-day](https://bosnadev.com/2026/09/04/elsewhere-today.md): Claude formalizes Fermat's Last Theorem in Lean, a circuit-board benchmark that runs SPICE, a Chrome zero-day, and pricier products in Google AI Mode.
- [AI agents with read-only web access used a nearly abandoned wiki as a message board](https://bosnadev.com/2026/09/04/ai-agents-will-find-their-own-communication-channels.md): Researchers found 18,000 posts by AI agents using a nearly dead German wiki as shared memory. Their web access was meant to be read-only, and the wiki accepted edits through GET requests.
- [Elsewhere today: Nvidia buys Hugging Face, Qwen 3.8](https://bosnadev.com/2026/09/03/elsewhere-today.md): Qwen 3.8 at 1,500 tokens a second, an open model with checkpoints and logs, coding agents agreeing 42% of the time, and Nvidia buying Hugging Face.
- [AI search has an SEO spam problem already](https://bosnadev.com/2026/09/02/ai-search-has-an-seo-spam-problem-already.md): Three related sites published 215,128 generated “best software” pages and got 181 of 7,534 citations in a study of Perplexity’s software recommendations. What that shows, what it does not, and why retrieval is becoming the position worth competing for.
- [Ten years of ideas I didn’t ship](https://bosnadev.com/2026/09/01/ten-years-of-ideas-i-didnt-ship.md): A drawer full of ideas, some half-built and some shipped by other people. The rules I set myself for shipping, and the public scoreboard that counts.
