Made new test prints on some off-cuts, using a slightly stronger developer solution than usual to see impact on max. depth. The main image (Eagle Creek, Oregon) is using 18% sodium acetate (curve corrected negative), the test strips are of 20% and 15% solutions (both uncorrected). The phone capture doesn't really show the differences too well, but I think I will go for the 18-20% from now on...

Why are we having fewer children?
(Interview with Berkay Ozcan, Professor at LSE)
- Couple formation happens at later age
- Women are choosing "careers" and not just "jobs"
- More people choose not to have kids at all
What else is going on? Short anser: we don't know yet
Even in countries providing a lot of support to parents, fertility rate has still declined

Berkay Ozcan: “Immigration is not a silver bullet for falling birth rates”
Berkay Ozcan discusses falling birth rates, whether immigration might provide the answer and what a smaller global population would mean for the environment.

Lab-grown algae remove microplastics from water
A University of Missouri researcher is pioneering an innovative solution to remove tiny bits of plastic pollution from our water. Mizzou's Susie Dai recently applied a revolutionary strain of algae toward capturing and removing harmful microplastics from polluted water. Driven by a mission to improve the world for both wildlife and humans, Dai also aims to repurpose the collected microplastics into safe, bioplastic products such as composite plastic films.

WELKER: You voted to hold Bill and Hillary Clinton in criminal contempt earlier this year for failing to comply with subpoena.
Why shouldn't the same standard apply to the former AG Pam Bondi?

Dutch farmland has a major water quality problem, in part due to the overload of manure ending up in ditches. Turns out that farmers have found a workaround: in just 7 years, they made 30,000 ditches disappear by filling them up, 1/3 of those illegally.
Bad for biodiversity and water management.

Hoe de sloten in Nederland verdwijnen
Jaarlijks verdwijnen duizenden sloten in Nederland, blijkt uit onderzoek van de Volkskrant, en dat gebeurt deels illegaal. Regels om de waterkwaliteit te verbeteren, geven boeren juist een prikkel om sloten dicht te gooien, en gemeenten handhaven nauwelijks. Wie daar kritisch op is, kan soms zelfs op intimidatie rekenen. ‘Als jullie terugkomen, druk ik met een shovel jullie auto in elkaar!’

🧼 Natural peptides from cyanobacteria offer eco-friendly solution to marine biofouling

Natural peptides from cyanobacteria offer eco-friendly solution to marine biofouling
A new CIIMAR study demonstrates that natural peptides produced by cyanobacteria are capable of replacing toxic biocides that dominate the market for anti-fouling paints used in the maritime industry. The use of these peptides as an active component brings direct benefits to the environment, the blue economy and marine biodiversity.

One of my VR Lighthouses died last month. These things are gyroscopically spinning 24 hours a day for, what, a decade now? Nearly.
No wonder. Mostly the industry seems to be settling on using head-mounted cameras rather than sweeping infra-red beams and receptors on the head anyway.
It is true that lighthouses give accurate positioning, but means I can't easily take the headset next door, say. Or to a party.
So inside-out, as they call it, is fine for the headset now and mostly okay for the hand-controllers.
But it offers no solution at all for the foot-trackers and hip-tracker that I need for puppetting the characters in the #vr #slimeVR #trackers

Equilibria: Fair Multi-Tenant CXL Memory Tiering At Scale

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.
