I don't disagree with anything you say in general or in principle... but if you actually bothered to even skim the report, you'd see that almost half of it is about data collection: existing academic research, best practices, chal

If you're a data analyst, then surely you must be familiar with (and recognize the usefulness of) proxy variables? If we can easily measure x + e, but not x, then our estimate of x is biased but comparisons of (x1 + e) - (x2 + e) are n

(1) it's something they do to make comparisons between countries easier, as different countries have different thoughts on what is/isn't considered edible, and also because it's easier to measure (e.g. using a very simpl

It's important to note that (1) the report uses a very liberal definition of food waste, that is, it includes inedible portions of foods such as pits, rinds and bones and (2) it does not account for the destination, so if you compost t

Mostly yes, though you can wing it a little bit by relying on swap and/or doing any big filtering operations up front. In my work, it's never been a problem, because you can cram a lot of data into 16 GB, millions of big polygon

Faster both in terms of querying and in terms of doing the kind of analysis you want and getting the answers you need. Of course, happy to acknowledge that different tools might work better in different scenarios. For example, I suspect tha

Not really, combining datasets in (Geo)Pandas is very straightforward, including spatial joins: https://geopandas.org/docs/user_guide/mergingdata.html#spati... Of course, it's all a matter of personal prefere

FWIW, even though PostGIS is pretty great, if your use-case is primarily offline analysis and you don't need the data to be permanently accessible or writable, consider not using a database at all. You can do a lot, a lot faster with e

I have a hunch, though, that often the problem is not emotional but actually physiological. If a ventilation system works well enough that air is not altogether too stale or humid or high in CO2, but not well enough to ensure the air is pro

That's a classic rent seeking argument, where people make money depending on how easy it is for them to sabotage something as opposed to how much they contribute.

That sounds like a cute analogy, but even though the wooden framework of a house is mostly see-through and somewhat modular, it would actually be quite cumbersome and effortful to say "okay, but for this particular wall I'm going

There's an interesting treatise, "L'invention de l'homme moderne" by Robert Muchembled, where he details how medieval Europe transitioned from a decentralized and low-trust environment to a centralized and high-trus

The probability of winning the lottery if you're a cheater is high, but the probability of being a cheater if you win the lottery is low. More generally, the probability of A conditional on B is not the same as the probability of B con

Also, if this is some kind of polyurethane, they're going to have a hard time convincing anyone that this is an environmentally friendly alternative to rubber tires.

I looked up the numbers for Aswan in the south of Egypt. Roughly 360 hours of sunshine or a bit more in the summer, 290 hours in winter months [1], so about 80% of max. If we look at direct normal irradiance instead, a more appropriate metr

A lot of the comments seem to conflate three or four different things: * built on-site vs. fabricated in (usually) a big woodworking shop * built according to an off-the-rack architectural design vs. built to the architect and clients'

Hence "depending on what is implied". You make a remark because something surprises you, and the reasons for that surprise might be benign or they might be racist.

There are probably situations where it's an innocuous remark, but surely you can see that depending on the tone and what is implied, it might be extremely offensive, not very different from saying something like "oh, you're a

No proof of this, but I imagine that (very) small fan bases have a very different dynamic from large ones. As a fan of a generally unknown artist, you're part of a small clique, you enjoy this thing that very few other people love so i

It probably depends on the kinds of projects you do, but this kind of "halfway there" PCB seems like a lot of fuss for not a lot of gain. Why not just design the PCB the way you want it look for the final product, and then, in pla

As others have pointed out, heating requirements (watt/m^2) are in fact linear which is why it's possible to more or less accurately calculate a building's insulation performance in watt/m^2/K, it's just that t

As an addendum, this winter I unfortunately found out that, at very low temperatures, the limiting factor might be the furnace, but it might also be the capacity of the radiators (or underfloor heating, or whatever) to shed heat. Tiny radia

Hm, heating is either switched off/on depending on a thermostat ("bang-bang") or in more sophisticated systems is regulated according to need (modulating control). It might be on 24/7 regardless of whether it's hot

Nitpick: really more like a 15% chance over 11 months. 1 - (1 - 5/10000)^330 => 0.152 (But I think you make a great point, it sounds like a tiny chance but it really does add up.)

Erik posts a comment on Hacker News, next thing you know, there's a military coup in Myanmar. Factually correct. The phrasing implies a causal relationship, which is what Wirecutter disputes.

Clearly it does add a new capability: it gives people an additional assurance that the mic is muted in a tamper-proof way whenever the switch is toggled, which is something that according to the article many are currently wary of.

You'd make this change alongside others that would require recertification and retooling anyway, and presumably a lot of those engineers have a full-time contract so that's not an additional cost. Overall assembly cost may be high
