arXiv 2607.22883 documents a "misguidance effect": show an LLM buggy code and ask for unit tests, and it does two bad things at once, generating more tests that assert the erroneous behavior as correct and fewer bug-exposing tests. Buggy code skews preference toward tests that ratify the bug. The fix is a one-line prompt change: replace the code-under-test with an LLM-generated specification docstring so the model targets intended behavior. Also improves multi-round feedback-driven pipelines. (arXiv 2607.22883)

CCP announced the migration covering code that has run on Stackless 2.7 since 2010. The approach is to run futurize across the codebase and then manually review roughly 20,000 places where Python 2 and 3 behavior diverges, including integer division (Simon Willison). No comple...
Allen Bargi's August 15 post hit 302 points arguing that AI collaboration rewards context-sharing, examples, and feedback over precise instruction (Hacker News). The pushback holds that the piece conflates management with leadership. mikeocool calls it "the most low effort ver...
Satya Nadella said companies routing everything through a single proprietary lab may not survive. His argument: you hand that lab your most sensitive business context, and the lab can turn it against you as a competitor. His prescription is an orchestration layer — keep the ha...
Willison launched datasette-apps (0.1a2) on June 18, hosting self-contained HTML+JS apps in a sandboxed iframe that run SQL against your data, read-only by default. He frames it as "Claude Artifacts reimagined for Datasette," artifacts backed by a JSON API to a relational data...
His conclusion is DuckDB matches or beats SQLite's safety for untrusted queries, but only with enable_external_access=false, lock_configuration=true, and a watchdog thread, since DuckDB lacks SQLite's opcode-based query timeouts. He ships a safe_duckdb.py helper and a Datasett...
I've been skeptical of "just have AI rewrite your codebase" advice because most of it comes from people who haven't actually done it in production. This week, three independent teams published results that changed my mind, with a very specific caveat. Reco.ai rewrote JSONata (...
