The open-source world is currently awash in reports of LLM-discovered bugs and vulnerabilities, which makes for a lot more work for maintainers, but many of the current crop are being reported responsibly with an eye toward minimizing that impact. A recent report on an effort to systematically find bugs in Python extensions written in C has followed that approach. Hobbyist Daniel Diniz used Claude Code to find more than 500 bugs of various sorts across nearly a million lines of code in 44 extensions; he has been working with maintainers to get fixes upstream and his methodology serves as a great example of how to keep the human in the loop—and the maintainers out of burnout—when employing LLMs. |

One of the more significant changes in the 7.0 kernel release is to use the lazy-preemption mode by default in the CPU scheduler. The scheduler developers have wanted to reduce the number of preemption modes for years, and lazy preemption looks like a step toward that goal. But then there came this report from Salvatore Dipietro that lazy preemption caused a 50% performance regression on a PostgreSQL benchmark. Investigation showed that the situation is not actually so grave, but the episode highlights just how sensitive some workloads can be to configuration changes; there may be surprises in store for other users as well. |
