Eisensteinon Direct retinal projection display for smart glasses using a meta-optic mirror

I find meta-analysis are better for understanding the current state of research on a particular topic.

"A systematic search of PubMed, Scopus, and Web of Science identified randomized controlled trials (RCTs) from 2010 to 2024. Eligible studies enrolled adults using BBGs before bedtime and reported actigraphy-derived outcomes. Random-effects meta-analysis was performed using the generic inverse variance method. The review was registered in PROSPERO (CRD420251034611).

Results

Three double-blind crossover RCTs (n = 49) were included. BBGs showed a non-significant reduction in SOL (MD = −4.86 min; 95% CI: −20.23 to 10.52; p = 0.54) and a non-significant increase in TST (MD = 8.75 min; 95% CI: −35.31 to 52.82; p = 0.70). No significant effects were found for SE (MD = −0.61; 95% CI: −7.58 to 6.35; p = 0.86) or WASO (MD = −1.47; 95% CI: −14.94 to 11.99; p = 0.83). Heterogeneity was low (I2 = 0%).

Conclusion

BBGs may provide small improvements in sleep, but current evidence from RCTs does not support significant effects. Larger, well-powered trials with standardized protocols are needed."

You haven't demonstrated why this matters.

Are you contending that complex systems cannot be more than the sum of their parts?

A market is nothing more than offers and counter offers.

A ant colony is nothing more than scent trails.

All life on earth is nothing more than reproduction with variation.

> This still falls under the purvey of statistical token generation.

Stating the mechanism does nothing to provide insight into capability. For instance: a nuclear power plant boils water by using fuel rods for heat. What does that tell us about the capability of nuclear power?

Asserting something purely by stating it does not prove anything but that you intuitively believe it to be true.

Eisensteinon Owners mourn spoiled food after firmware update bricks Samsung smart fridges

"In theory but the benefit would be pretty negligible i think. Let's say for argument that most food is water and your fridge is 25% food and 75% air. The specific heat of air is 1 kJ/kgK, specific heat of water is 4.2 kJ/kgK. But also the density of air is 1.2kg/m3 and the density of water 1000kg/m3. Assume 1 m3 volume. So that would be 250kg food and 0.9 kg air. To change temp by 1C would take .9kJ for the air and 1050kJ for the food. So the air in a fridge holds a fraction of a percent of the total thermal mass of the contents. Whether or not that air changes temperature by a few degrees won't change things much at all. You would spend far more on balloons that you would save on energy."

You might be. Running another agent doesn't load a set of new weights. It creates a new KV cache for the agent and adds the prompts to the queue. Its just another inference turn.

Eisensteinon M5 Ultra Mac Studio Review

A 5090 has a 1.79TB/s memory bandwidth. Qwen 3.8 27B NVFP4 is 22GB. You cannot generate tokens faster than the weights can traverse the GPU memory, so that makes max generation speed without MTP to be 81T/s. Say MTP is giving you 0.5 acceptance rate (very good), that is 1.5 * 81 is 121T/s. Even with a perfect acceptance rate you would only get 162T/s.

Some highlights:

Feb 2024: "I believe we're reaching the upper limits about what generative AI can do and how accurate its outputs can be."

July 2024: "Generative AI, as I said back in March, is peaking, if it hasn't already peaked. It cannot do much more than it is currently doing, other than doing more of it faster with some new inputs"

July 2024: "Generative AI models aren’t getting more energy-efficient, nor are they getting more “powerful”

August 2024: "generative AI is a dead-end technology that has peaked”

Dec 2024: "I also warned you in March that generative AI had already peaked.”

Jan 2025: "I believe we’re at peak AI"

February 2025: "Sam Altman deputizing Orion from GPT-5 to GPT-4.5 suggests that OpenAI has hit a wall with making its next model, requiring him to lower expectations"

April 2025: "It also, at this point, is pretty obvious that generative AI isn't going to do much more than it does today."

August 2025: "These models have clearly hit a wall where training is hitting diminishing returns"

Nov 2025: "the fact we're running out of high quality training data and we're hitting the walls of scaling laws, in the training paradigm, these models aren't getting better. What we're seeing today is pretty much what they're always gonna be like"

Eisensteinon Smartphone LED detects hidden cameras with AI

Can't a thermal camera can do this? It should be able to detect any difference in ambient temp, even a few degrees, and a CMOS sensor gets warm, not to mention any wireless transmitters, power sources, and ICs. Turn off everything in the room and walk around with a ~$100 ali express handheld thermal camera.

Eisensteinon OpenAI Jalapeño: Better than Nvidia Blackwell

You are adding an extra step though. Use a closed loop coolant and remove the heat from that coolant with the heat exchanger. Why would evaporation in between be more efficient?

Eisensteinon How much of HN is AI?

So, they resolved solved problems but without centralized systems.

It seems to me that people don't want to run their own security upon which they have no recourse if they fail, and don't think that benefits of centralized systems are worth giving up for the dubious benefits of a decentralized trust. Imagine if the scams for the currencies occurred with voting systems, with no way to undo it.

The technologies just didn't do anything that more than a small number of people wanted.

How is that different from not using evaporative cooling and just putting the heat exchanger on the burner?
