This tree ornament sure is hard to photograph

Feeling smug after a bit of slactivism: Just e-mailed Michešl Martin and Simon Harris to ask them to stop hanging around with nazis and perverts.
I.e., to stop posting on x.com

An excellent summary here via @… about how the structures of our civil society have failed to stop ICE from becoming Trump’s Brownshirts.
The one thing the piece omits: someone •is• stopping ICE. It’s the citizens filling the streets, honking and shouting and filming and generally harassing ICE, doing the work our government has failed to do. If it were not for that response being so widespread, sustained, and forceful, we’d be in far worse place right now. https://mastodon.social/@AnnaAnthro/115616389777857234

Abstract: Memory dominates datacenter system cost and power. Memory expansion via Compute Express Link (CXL) is an effective way to provide additional memory at lower cost and power, but its effective use requires software-level tiering for hyperscaler workloads. Existing tiering solutions, including current Linux support, face fundamental limitations in production deployments. First, they lack multi-tenancy support, failing to handle stacked homogeneous or heterogeneous workloads. Second, limited control-plane flexibility leads to fairness violations and performance variability. Finally, insufficient observability prevents operators from diagnosing performance pathologies at scale.
We present Equilibria, an OS framework enabling fair, multi-tenant CXL tiering at datacenter scale. Equilibria provides per-container controls for memory fair-share allocation and fine-grained observability of tiered-memory usage and operations. It further enforces flexible, user-specified fairness policies through regulated promotion and demotion, and mitigates noisy-neighbor interference by suppressing thrashing.
Evaluated in a large hyperscaler fleet using production workloads and benchmarks, Equilibria helps workloads meet service level objectives (SLOs) while avoiding performance interference. It improves performance over the state-of-the-art Linux solution, TPP, by up to 52% for production workloads and 1.7x for benchmarks. All Equilibria patches have been released to the Linux community.

Weekend #Plankton Factoid 🦠🦐
The polar vortex has caused a cold snap here, and the Great Lakes are rapidly forming ice. Under this thick ice, algae are growing. These are normal diatom phytoplankton, which change to form thick chains, attaching to the underside of the ice where light is optimal. We clearly see this brown ice and water in the wake of our icebreakers. This occurs near the pole…
