Welcome to the LWN.net Weekly Edition for May 21, 2020
This edition contains the following feature content:
- The PEPs of Python 3.9: an update on the final changes that found their way into the upcoming Python 3.9 release.
- The state of the AWK: it may be an old tool, but it's still interesting.
- Ongoing coverage from OSPM 2020, including:
- The weighted TEO cpuidle governor: an attempt to improve idle-time predictions.
- Testing scheduler thermal properties for avionics: an in-progress test bed to evaluate thermally-oriented scheduler changes.
- Utilization inversion and proxy execution: using load tracking for task placement can lead to some strange inversion situations; fixing them may not be entirely easy.
- The many faces of "latency nice": a complex and inclusive session on an incompletely designed feature.
- Scheduler benchmarking with MMTests: a test suite developed for memory-management benchmarking finds a new use case.
- Evaluating vendor changes to the scheduler: mobile vendors make a lot of tweaks to the CPU scheduler; why do they do that and what is gained from it?
- Bao: a lightweight partitioning hypervisor for mixed-criticality workloads.
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.
