If a jurisdiction switches to renewables too quickly, it damages the electorate’s tolerance for green policies.

I suspect that the lack of ability to form nulls in the beam is as big or even a bigger limitation than the reduction in gain when going from a big array to a phone. The SNR in Shannon’s Law has a log in front of it, but spectrum reuse is m

My claim is that these are not the same market as the traditional Starlink service.

Zyrtec/cetirizine is a weird one. Everyone seems to agree that it is a second-generation antihistamine. The FDA seems to play along. But there is no particular shortage of anecdotal evidence of people who find it quite sedating (hi th

I know little about radiology, but MRI is a 3D medium. I would not be at all surprised if one could slice an MRI the wrong way to produce a 2D image that fails to show a feature that exists in the source data.

If someone sells you 12345.55 EUR vs USD at a rate of 1.12345, how many EUR do you think you end up with? Do you think all market participants even agree? What if the rate is 1.123456? For added fun, you can introduce division. Some syste

Not for prefill. I suppose if you just want to imagine what generation speed looks like in the current generation of TUIs, it’s an okay visualization.

That’s an awful visualization. I can skim code quite quickly, but not when it shows up one character at a time in a small window, modem style. At least that site should draw out a full page then start replacing that page with the next, st

As another way to estimate this, here’s a data sheet for some microbubbles: https://pdf.benchchem.com/1673/Application_Notes_and_Protoco... So 1-5e8 bubbles per mL, and let’s suppose you inject 5mL. (I have no idea wha

I never studied these specific classes, but my immediate intuition is that an n-input fan-in AND or OR gate can be reduced to a tree of 2-input gates with depth O(log(n)), which preserves polylog complexity, so surely AC = NC. Wikipedia agr

When you say "physically based rendering" do you mean that one could build a PBR model based on the (unrolled?) xray data, render that model, and be able to see the ink? edit: I found this: https://scrollprize.org/

Do you know what kinds of features the model is picking up on to distinguish ink from papyrus? And did you have any labeled data (images where a human expert has identified ink or perhaps a scan of a burnt scroll with known content) to hel

I was surprised that there was no mention of two things: 1. Retrying a non-idempotent request on a failure type that does indicate that no action was taken is not necessarily safe. 2. It’s possible and actually fairly common to design a bac

I’ve been to datacenters, but not the huuuge ones people seem to talk about in the context of AI. They are noisy inside (due to air cooling, which is largely avoided by the tech in the OP), but they’re entirely unremarkable outside compared

by amluto 4mo ago
Indeed. If the datacenter uses less total power, it produces less waste heat. If you manage to use the waste heat to avoid generating heat somewhere else (that the article calls heat recovery) then there’s a further reduction in total heat

Actual heating due to human energy use is not really a big deal except perhaps locally. Climate change is caused by changing how much heat the earth retains from the sun. Maybe if we stopped using fossil fuels and used immense amounts of n

This opens up an interesting synergy: district heating. 45C is low but not unworkable for a district heating loop, and a data center might be able to make a nice pitch to a community if the data center offers to provide heat to a district h

I find the workflow of fitting Gaussian splats and then immediately turning them into voxels to be rather surprising, too. I can imagine some performance benefits at large scale, or maybe a reduced tendency to generate certain types of art
