With the emergence of more processors with 64 cores or more, I'm thinking more about whether it makes sense to implement a hypercube virtualised on a single chip with a single vector of memory, or as a literal hypercube of 64 (say) RP2350s. I understand the problems of transferring data across a hypercube, but I don't have a good feeling of how the bus contention on a multicore processor scales. What should I read?

"We don’t really think about our future – we remember it",
said Dr Hal Hershfield, who studies how humans think about time and how that influences our emotions and behaviors.
When we daydream or envision ourselves at a later point, we essentially create a memory.
We then use these memories to construct our ideas about the future.
This process is called “episodic future thinking”;
it supports our decision-making, emotional regulation and ability to p…

Vietare cose ad altre persone è facile
L'Australia ha adottato misure per obbligare le aziende di social media a impedire ai minori di 16 anni di avere un account, e si parla sempre di seguire l'esempio del Regno Unito. Oggi voglio spiegare brevemente perché ritengo che sia una cattiva idea.

The thing that Renee Good now knows, that Tortuguita knows, that Heather Heyer knows, that I only know because I glimpsed for a second, is that when you die fighting oppression you live forever in that memory of resistance. When we carve their names into a monument, along with all the other names of the murdered and disappeared, that will stand, perhaps, across from the statue of Willem in the park where the Northwest Detention Center once stood, they will always be reminders of what it looks like to sacrifice everything in order to be on the right side of history.
The names of those who resist live as ghosts, summoned by name to haunt future oppressors, summoned by name to awaken our own conscience to the call. Martyrs, whispered like the White Rose or yelled as a threat like John Brown, cannot die so long as any of us with a bit of spine carries even an ounce of humanity.
It is possible to die knowing you did the right thing, and I have felt it. There is an acceptance that is impossible to imagine without being there, without feeling it for yourself. You have nothing to fear in resisting, even if it ends you. But you will never forget the shame of doing nothing if you fail to.

Myanmar releases 6 journalists in pre-election amnesty - Committee to Protect Journalists
Bangkok, December 4, 2025—The Committee to Protect Journalists welcomes the recent release of six journalists in Myanmar as part of a pre-election amnesty of more than 3,800 political prisoners, but urges junta authorities to free all remaining jailed members of the press. Those freed are Zaw Linn Htut (Phoe Thar), Htet Htet Khine, Nay Naw, Nyein Chan Wai, Aung San Lin, and Sithu...

Abstract: We study the problem of robust forecast aggregation: combining expert forecasts with provable accuracy guarantees compared to the best possible aggregation of the underlying information. Prior work shows strong impossibility results, e.g. that even under natural assumptions, no aggregation of the experts' individual forecasts can outperform simply following a random expert (Neyman and Roughgarden, 2022).
In this paper, we introduce a more general framework that allows the principal to elicit richer information from experts through structured queries. Our framework ensures that experts will truthfully report their underlying beliefs, and also enables us to define notions of complexity over the difficulty of asking these queries. Under a general model of independent but overlapping expert signals, we show that optimal aggregation is achievable in the worst case with each complexity measure bounded above by the number of agents $n$. We further establish tight tradeoffs between accuracy and query complexity: aggregation error decreases linearly with the number of queries, and vanishes when the "order of reasoning" and number of agents relevant to a query is $\omega(\sqrt{n})$. These results demonstrate that modest extensions to the space of expert queries dramatically strengthen the power of robust forecast aggregation. We therefore expect that our new query framework will open up a fruitful line of research in this area.

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.
