Yeah I think this might actually be backwards; the Soviet Union had explicit production targets, and (iirc) in like the 70s they actually had more industrial output than the US. Remember the "missile gap," when the US was concerne

I don't think my point was straw-manning the article. The article directly conflates economic output with manufacturing output, by using manufacturing signals (like power consumption!) as a corollary for some hidden, Real Economy. That

I think America in its best expression is an amalgamation of many different backgrounds and attitudes. Even differing opinions on the functioning of democracy, though I personally think some opinions denigrating democracy are a bit out of b

Economics experiments are actually a thing. You can have natural experiments, or you can uncover patterns in data, or you can try controlled experiments (in microeconomics), though that sometimes just feels like applied psychology. I dunno,

Also, "I become richer just because I think I'm richer" was actually a thing Donald Trump once said in a deposition: "My net worth fluctuates, and it goes up and down with markets and with attitudes and with feelings, ev

That's a fair counterexample. In that case, you could argue that "true GDP" didn't change at all, merely our measurement of it had error. But pretty soon you ask 'well, what is the real signal?' And it's t

If you can truly come up with an objective measure of wealth, I believe there might be a (quasi) Nobel Prize in economics for you. The reason economics is hard, in part, is that there isn't some core firmament you can rest on; there is

I have a lot of respect for economists, I know several. They are among the most rational people you shall ever meet. And they are very aware of how incomplete their tools are. But they do a lot with such tools that is worth knowing.

Two quick thoughts… one, because every transaction in theory happens because the purchasing party values the good or service more than the money, every transaction does — in theory — create wealth, velocity of money is sort of measuring a p

Arguing that manufacturing is strategic is not the same thing as manufacturing being “all that matters in an economy.” There’s a logical fallacy in your rebuttal.

China has major structural weaknesses in its economy that are currently overshadowed by the US cr*pping its own and its allies’ pants. Specifically: there is not much of a home grown consumer economy; they have driven growth too heavily on

I prefer my economic takes from economists, or people who actually study these things. -there is more to an economy than manufacturing. Using manufacturing metrics to rate an economy is like scoring a soccer game based on how far your playe

I saw this at a DSO* presentation ("Darpa's Darpa") back in ~2018. Hope they've gotten some early traction, that was some of the least wild crap that was being presented. My company was pitching holographic cameras, and

FYI, my colleagues in the past have used Metashape, if you're in the market for an OTS solution. There is also Epic's RealityCapture; I have not used either one, but as far as I can tell capture density and quality matter a lot. F

That’s going to depend a whole lot on their budget, your capabilities, and the final requirements — is this being used for visuals, or metrology? I have suggestions for getting visual fidelity but if you’re looking for an explicit 3D model

You could try generating per-view depth maps, going to a point cloud and meshing from there. (I suspect splats may reduce your accuracy as an intermediate.) I’m not aware of a fully-baked workflow for that — though it may exist. The first s

Walgreen’s was closing stores anyway and used the pandemic shoplifting as an excuse… but it was never the actual reason. Crime is at historical lows.

Except for leverage... but the general point remains that the upside is capped and the downside in theory is not.

I'm hardly an expert, but when I switched to lead-free solder (for the same reason, had a young kid around), the only change that helped me was soldering at a significantly higher temperature. The lead free stuff still doesn't beh

I don’t think you get much iron in your food from seasoned cast iron; the polymerized oil is an impermeable barrier. We have a lucky fish and it has what looks like rust all over the surface because the metal is directly exposed to the cook

That’s not a fair comparison, The New Yorker has always had a different relationship with its writers. A freelancer who writes for The New Yorker is likely a highly respected journalist/author/other luminary. Their staff writers a

I think the barrier to commercialization is the lack of demonstrated economic value to having push button splats. There's no shortage of small teams wiring together open source splats / NeRF / whatever papers; there's a

This is spot-on. Note that the aperture on the camera was quite large, I want to say on the order of 100mm? They sourced really exotic hardware for that cinema camera. They also had the "Immerge," which was a ~1m diameter, hexagon

It's more expressive than mesh-and-texture, which is the default: it can represent things with poorly defined edges or transparency. Also, because it's solved via GD, you tend to get better fidelity than traditional photogrammetry

It renders pretty fast, actually. The knock on splats is that they create huge file sizes for video data.
