The Software Engineering Radio podcast has put up an interview with graphics maintainer Dave Airlie. Much of what is in there will not be news to LWN readers, but it is an interesting overview of the life of a large-subsystem maintainer.

I was talking to a few of the Rust people, and I thought: these are very young people, these are a group of people in their 20s, maybe 30s, they are a younger cohort of developers than the people I am normally used to dealing with. I thought there was maybe a good way we could bring these groups together. I think that having young people coming into the kernel using Rust is valuable... So I thought that I should be supportive of bringing Rust into the kernel.

The splice() and vmsplice() system calls are meant to improve performance for certain data-movement tasks by minimizing (or avoiding altogether) system calls and the copying of data. They also have a long history of security problems. The recent flood of LLM-discovered vulnerabilities has drawn attention, once again, to splice() and vmsplice(); as a result, they may end up being removed altogether.

The EFF has a blog post looking at a new bill in California that would exempt open-source operating systems from the Digital Age Assurance Act passed last year, but has problems of its own:

While the open source exemption, if passed, would improve the law, the remaining amendments proposed by AB 1856 would require all web browsers and websites to request and collect users' ages. This is an expansion of last year's AB 1043's age-bracketing system that compounds its constitutional harms to users' speech, privacy, and security.

[...] EFF understands this amendment to exempt open-source operating systems from the requirement to collect and transmit users' age-bracket data. That is a definite win for open-source developers. The bill is narrower now than it was before, and lawmakers clearly responded to concerns raised by EFF and the broader open-source community.

Some important questions still remain—for example, it is unclear how the law would apply when an open-source operating system is incorporated into a commercial product or service. And, given the structure of where the exemption is placed under the "operating system provider" definition, lawmakers could stand to clarify that the exemption applies to open-source operating systems and applications.

LWN covered California's age-attestation law in March.
