A year after filing to IPO, still-private Cerebras Systems raises $1.1B | TechCrunch
Cerebras initially filed to go public in September 2024 but ran into several regulatory delays due to foreign investments.

Here’s the lightning sketch of Paul’s Treatise Against Efficiency that I’ve never written:
1. Efficiency is asymptotically inefficient: as costs approach zero, the cost of further reducing them approaches infinity.
2. Efficiency prioritizes the measurable over the difficult-to-measure.
3. Efficiency prioritizes what those in power see (or imagine) over on-the-ground reality.
4. Following from 2 and 3, efficiency reduces the amount and quality of information flowing into a human system.
5. Efficiency foments institutional inflexibility.
6. By removing slack, efficiency causes small failures to cascade more readily and increases the risk of catastrophic failure.
7. Following rom 4, 5, and 6, efficiency trades small costs for massive risks: from failures, from missed opportunities, and from inability to adjust.
8. Efficiency, when pushed, strangles the emergent phenomena that in the long term create all new things of value.
9. Thus, although it can be a by-product of evolution, efficiency as a goal in itself strangles evolution.
10. Efficiency as a goal strangles joy.

CRAN Task View: Optimization and Mathematical Programming
This CRAN Task View contains a list of packages that offer facilities for solving optimization problems. Although every regression model in statistics solves an optimization problem, they are not part of this view. If you are looking for regression methods, the following views will also contain useful starting points: MachineLearning, Econometrics, Robust Packages are categorized according to the following sections.

AI-Based Stroke Rehabilitation Domiciliary Assessment System with ST_GCN Attention
Effective stroke recovery requires continuous rehabilitation integrated with daily living. To support this need, we propose a home-based rehabilitation exercise and feedback system. The system consists of (1) hardware setup with RGB-D camera and wearable sensors to capture Stroke movements, (2) a mobile application for exercise guidance, and (3) an AI server for assessment and feedback. When Stroke user exercises following the application guidance, the system records skeleton sequences, which a…

I just finished Guild Wars: Prophecies. It took me 19.5 years.
I created my first character way back when the game was new, but I never finished the campaign. The upcoming Reforged update got me interested again. Together with a friend and 3 very friendly strangers we played through the remaining 3 missions.
From boss tactics to tounge-in-cheek comments about the dated cutscenes It was just the perfect MMO game night for me.

Weak-strong uniqueness for general cross-diffusion systems with volume filling

Weak-strong uniqueness for general cross-diffusion systems with volume filling
The weak-strong uniqueness of solutions to a broad class of cross-diffusion systems with volume filling is established. In general, the diffusion matrices are neither symmetric nor positive definite. This issue is overcome by supposing that the equations possess a Boltzmann-type entropy structure, which ensures the existence of bounded weak solutions. In this framework, general conditions on the mobility matrix are identified that allow for the proof of the weak-strong uniqueness property by me…

I'm #ActuallyAutistic, and I love this woman deeply. I have been a huge fan of her music, especially my special interest in her song “Loin d’ici” (ESC Version) since May 14, 2016.
But now, watching Taylor Swift, Cœur de Pirate, and other artists slowly take her place feels like an unspoken farewell, like a song fading softly into the distance. It’s as if she herself is tell…
