A very interesting concept whose maturity is being raised. There are many sky surveys (some originally intended for NEO searches) that have been opportunistically mined for novel transients. It turns out that if you look, there is a lot goi

I really like using make for data pipelines as you suggest, and thanks for pointing out your package. In this pipeline use case, you have base data, and a series of transformations that massage it into usable results. You are always revisin

This is just the “job server” which you can read about in the Gnu make documentation, which is excellent. https://www.gnu.org/software/make/manual/html_node/Job-Slots... Basically you can specify a “-j 2

Ok, eventually, if all the properties flip and are maximally developed. That would take many years. And even a quadplex is different than a multi unit apartment building.

I don't know enough about Gainesville to comment seriously on this particular change, and the article is light on details. But the gloss it gives is this: > "...allow duplexes, triplexes and quadplexes to be built on land curre

This explanation loses me at "infinity per dB" ... and I'm an EE. I think you're trying to cover too much ground here, it's really confusing to try to understand what you mean. I believe the comment you're resp

It is the identity for the signal, but RIAA equalization cuts the high-frequency noise that's characteristic of needles in grooves. signal -> [HF boost] -> [needle adds HF noise] -> [HF cut] -> same signal, less HF nois

Probably not responsive to the likely orientation of the OP, but a legit option. A lot of the reason we know anything about climate is to do with government - NOAA, NASA Earth Science, EPA.

There are small-to-midsize firms working to get climate-related remote sensing data into the hands of farmers and others. Here's one whose chief scientist is really exceptional: https://www.hydrosat.com Here's another

Another disastrous externality. Cheap to produce, hard to contain after it's out there.

It would appear that although Capitalism has a solution, Capital and Capitalists don't like that solution (effluent taxes).

This tweet from Kevin Murphy announces the camera ready version of his new book is available. An earlier draft version of this book was discussed before on HN, see: https://news.ycombinator.com/item?id=30552869

This comment and GP comment open up a helpful learning experience for a casual/occasional user like me. This distinction between initial value problems (IVP, one endpoint known, hence a “time” differential equation) and BVPs (both endp

I guess you could go through recent Nobel prizes (in physics) and see how many came from astrophysics/astronomy vs. Earth-bound physics? One recent astrophysics Nobel off the top of my head is the discovery of dark energy (whatever it

It's hard to see through the fog of breathless reporting in that link. Here's one closer to the source: https://blogs.nasa.gov/webb/2022/06/08/webb-engineered-to-en... It seems like they have 4

Sometimes called the "Bayesian dogma of precision" -- to any state of nature, you can assign a crisp probability (e.g., https://sipta.org ). For your disease example -- if you don't know the accuracy of the test (&

I assume "acting as if driven by a mission to do fundamental work in solving camera problems" -- as opposed to just looking for a quick product opportunity.

You’re making an interesting point here. I’m resistant to it because some analysis I do (say, inferring atmospheric composition from the spectra of light you shine through the atmosphere) does fit rather well in the Bayesian setup. In a ver

They are choosing to peg the article to the SF recall, where there were competency issues as well as political valence. Even more relevant are the elections in the East Bay that returned progressive candidates, and the mayoral election in L

Yes, one has to be careful about guessing what they probably did, because the processing was actually pretty complex, and astrophysics image processing is in general quite advanced. Saturation of the digital numbers coming from the detector

Like others, I’m surprised at this. You are aware that stainless is softer than common steel, and definitely more likely to strip out? They are more expensive, but best reserved for times when their softness is worth trading for corrosion r

Fantastic short article with some tidbits and puzzle pieces of this oft-told story that I had not known about before. Also, due to an outside writer, kind of a respite from the typical Quanta breathless tone. (They do an excellent job, bu

I’m afraid it is such a comment. HN is over-provisioned with “just asking questions” climate skeptics who use these points. Your objections and hypotheticals are generic and do not reckon with what we do know about the specific problem of c

The reason I linked the NCA above is to clarify that we have data on the severity of this problem. Everything you said above about Science versus Policy is true, as a generic matter. Problem is (as you can see in the GP comment that sparked

OK, well, here’s a good summary of the science part: https://science2017.globalchange.gov/ It really doesn’t seem religious to me. I know a few people who work in this area and they are just normal physical scientists. Most
