Welcome to the LWN.net Weekly Edition for March 20, 2025

• Oxidizing Ubuntu: adopting Rust utilities by default: a tool that minimizes the risk of swapping out a set of core utilities.
• Better CPU vulnerability mitigation configuration: deciding which Spectre mitigations to build into a kernel is not a simple task; perhaps a more intuitive set of configuration options would help.
• Warming up to frozen pages for networking: a core memory-management transition runs into a bit of a snag.
• Looking forward to mapcount madness 2025: forward progress on one of the most challenging problems in the kernel's memory-management subsystem.
• The burden of knowledge: dealing with open-source risks: a FOSS Backstage talk on evaluating the risk associated with development projects.
