Welcome to the LWN.net Weekly Edition for September 5, 2019

• Maintaining the kernel's web of trust: the public key servers aren't working anymore, so the kernel community takes web-of-trust management into its own hands.
• Bias and ethical issues in machine-learning models: a pair of conference sessions on machine-learning bias.
• Kernel runtime security instrumentation: a proposed Linux security module for attack detection and response.
• Change IDs for kernel patches: an attempt to improve the connection between Git commits and the discussions that lead up to them.
• Examining exFAT: the legal obstacles to merging the exFAT filesystem module may have gone away, but technical and procedural issues remain.
• CHAOSS project bringing order to open-source metrics: how does one objectively measure the health of a project?

This week's edition also includes these inner pages:

• Brief items: Brief news items from throughout the community.
• Announcements: Newsletters, conferences, security updates, patches, and more.
