Elon Musk has said that actuators comprise 56% of the Bill of Materials cost for Optimus. A year ago, we dove deep into an exhaustive look through the public companies that touch the robotics supply chain. While general-purpose, humanoid robots are further in the future, the pathway there will be immensely profitable for many of these companies. Read here: citriniresearch.com/p/thematic-pri…

Banger paper from Meta FAIR. They introduce Autodata, an agentic data scientist that builds high-quality training and evaluation data autonomously. The headline result: on a CS research QA task, an Agentic Self-Instruct loop produces a 34-point gap between weak and strong solvers (43.7% vs 77.8%), while standard CoT Self-Instruct on the same setup produces a 1.9-point gap (71.4% vs 73.3%). The agent generates questions that actually discriminate between models. The method: An orchestrator LLM directs a challenger agent to generate examples grounded in domain documents. A weak and a strong solver attempt them, a judge scores the outputs, and the orchestrator analyzes the failures and prompts the challenger to regenerate from new angles until quality thresholds are met. The system also meta-optimizes itself. An outer loop tunes the agent's instructions based on which harness changes lift validation pass rate. Over 126 accepted iterations, validation pass rate climbed from 12.8% to 42.4%. They processed 10,000+ CS papers and produced 2,117 quality-filtered QA pairs. Existing self-instruct pipelines do not control data quality. Autodata reframes data generation as an agent loop, spend more inference compute and the data gets harder, which gives downstream RL a real lift.

A very powerful explosion has just occurred at one of Bucharest's main thermal power plants. Over 30 tonnes of fuel at the site have ignited. No further details are available at the moment.





Most people might miss the biggest benefit of sauna You need to get really really hot… Your core body temperature needs to hit 102.4°F (39°C). For reference, a fever is anything above 100.4°F (38°C) So I swallowed a temperature monitoring pill. It goes through your digestive tract and precisely measures your internal temperature every 30 seconds. When your core body temperature hits the goal of 102°F, your body releases these proteins (heat shock proteins - HSPs) that clean up your body’s debris. I was curious what time my body hits this goal because up until now, I’ve been doing 20 mins of 200°F dry sauna. … it turns out it takes 31 minutes It feels like you’re dying. I didn't expert such pain and panic. Before this experiment, I did over 200 sauna sessions at 200°F for 20 min. This means I likely never achieved the heat shock protein (HSP) threshold at 102.4°F (39°C), which deprived me of so much sauna-health goodness. If your sauna doesn’t heat up to temperatures allowing your core temperature to reach 102.4°F (39°C) or you struggle to tolerate heat, do not be discouraged. The dry sessions I did at 200°F (93°C) for 20 min still showed incredibly health benefits. My previous 20 min sessions still showed: 1) 10+ yr reduction of my vascular age 2) 87% reduction of microplastics 3) detox of environmental toxins 4) fertility marker improvement Will report back once I have results on this new protocol…



I’ve seen a few people promote a theory that if X brings in new communities (e.g., women, vloggers) that it will somehow damage their community’s experience. This is categorically false: the Timeline algorithm serves tons of niches that you never see. Growth of new audiences will not pollute your Timeline (and if it does, that is a failure of the algorithm and we will fix it). X is for everyone and the product only gets more resilient and more relevant when more people are on here.

Ever since I was a little kid the concept of taking a man’s (or anyone’s) last name has been so repugnant to me I cannot believe people actually do it and do it without any hesitation
