living space isn’t remotely a concern, if we all (the whole world) lived in a single mega-city as dense as NYC it would be about the size of Texas

light also isn’t much of an issue, we could power the world with a solar array the size of New Mexico

fertile farm land, stable temperature, and distribution are much much much larger issues

living underground might be good for reducing electricity needs for heating and cooling, or avoiding certain natural disasters… but probably isn’t very useful for much else
> The same exact problem, vote buying, exists in every form of democracy. Secret ballot is supposed to solve that. And has nothing to do with direct, liquid or representative democracy.

Sure, liquid voting can solve vote buying by making delegations and individuals' votes secret with software (afaik the problem of a person being able to secretly delegate their vote to another person who is in turn able to vote secretly is basically unsolvable with pen and paper and ballot boxes though, unlike regular secret ballots)

But liquid democracy with secret ballot so voters are unaware that another person has delegated voting power to them can introduce a new edge case issue though. Two people have similar views on most issues so each of them secretly delegates their vote to the other person. This means that neither of their votes are cast for any actual proposal they actually both would be likely to support (and anyone else delegating their vote to one of these people also casts no vote)

[FWIW I'm talking about a form of liquid democracy similar to that outlined in the paper, where votes are delegated to individual neighbours who in turn may delegate to people they trust, not the form that looks more like representative democracy but you can pick different representatives for different issues)
Why do you answer "yes" when the answer is obviously "no"? No, 60k miles is not a good estimate for how long ICE powertrains usually last. Truly baffling reasoning.

Another example: iPhones have a 1-year warranty but usually last much longer than that.
when paired with high voltage chargers meant for 300 mile batteries, you can reach 40mi (80%) in no time

I plug my prius PHEV into a 110v socket at night and it serves my 25mi daily driving just fine.
SIMD is a very powerful parallelization technique, with marvelous gains whenever I see it used. It seems like a fundamentally more efficient form of compute, but is very difficult to design algorithms for.

I'd argue against "SIMD" as being "RISC", since you need all sorts of complicated instructions (ex: gather/scatter) to really support the methodology well in practice.
Yes, and ZLib provides an excellent example of how to do this (it's called braiding in the source code). There's an additional initialization and combination cost though. It doesn't really make sense for short messages.

Most of the US is solving this by building sideways (i.e. sprawl). It’s far cheaper than digging down, at least in the short term.
Mh, from Enphase catalogue in my country (France) I do not see such data, the IQ8 are not on sale here and IQ7 variants arrive at maximum at 315 VA for the IQ7X-96-2-INT witch is the top performer on sale here. Anyway, it's still less than classic string inverters even if they give "resilience" and "installation freedom"...

It seems like CRC inherently depends on results from earlier calculations, so it would be hard to parallelize like that. You could potentially do multiple independent CRC calculations in parallel, but then you're getting into more niche use cases.
Neighbourhood roads don't see 18-wheelers. Additionally a 2x increase in weight results in a ~20x increase in damage [0]. That's certainly not negligible and will eventually have to be factored into car taxes. The same is true for heavy trucks though: subsidies on road damage/maintenance disincentivises more efficient modes like rail.

With that level of violence it is the same scenario and the same outcome for a car.

First of all, the entire stimulus was $4.5 trillion, and most of it was allocated to handouts. A lot of the handouts were necessary, like expanded unemployment, but others were complete wastes of money, e.g. giving checks to families making 6 figures or forgiving loans for billion dollar "small businesses."

Second of all, QE isn't money given to the banks. When we have a deficit, the government sells bonds to banks. "Naturally" this would drive up interest rates for businesses because unlike the government, they can't issue an infinite number of IOUs and have to compete for a limited amount of liquidity. If interest rates rise too much, businesses will be forced to shut down, especially when people spend less money during a pandemic. Quantitative easing is a tool that allows the Fed to lower interest rates purchasing by these bonds back from the banks. The more debt the government issues, the more debt the Federal Reserve needs to purchase in order to lower interest rates. Basically, the root of the problem is that Congress is incapable of balancing a budget.
I don’t think you understand the purpose of treasury bonds as an asset.

Oops, my bad. Hazel does the OCR, because the day I was setting that pipeline up, I was able to get it working first. DT definitely does all the rest. I have smart rules set up in it for all the bank / credit card / loan statements we get, certain types of email I archive, and a bunch of other stuff.

In all cases, my workflow is the same: get a file onto my computer and into DEVONthink’s inbox somehow. For email, that’s using the DT plugin in Mail.app to import the message(s). For downloaded files, it’s using Hazel rules to move them into it.

Again, none of that’s stuff I couldn’t do by hand, but neither is really anything we do with computers, right? I’d rather script it up once and let it handle the toil for me every day.
> This is a worldwide assessment. Look at Northern Europe, and notice the complete lack of dots on the map.

I'm not quite sure what you're trying to say here. Northern Europe generally doesn't need the kind of sites that this study was looking for (a pair of locations vertically separated and horizontally close with a river close to the lower location); they already have "once-through" hydro plants on rivers with reservoirs high in the mountains.

> Want you bet your freezing bottom on it? "Less likely" does not cut it for a vital commodity.

I don't have to "bet my freezing bottom" on it. The "less likely" part means lower expected value of energy needs not satisfied by a combination of solar and wind power. This lower expected value translates into lower expenditure of backup supplies such as synthetic gas being expended for that purpose, and therefore the lower average annual cost of using such supplies. That makes this approach viable.

> To be fair in this case, self-service is objectively worse than having the shopkeeper grab everything you want.

even this depends on the type of shopper you are. if I'm buying a bunch of pasta, curbside pickup is great, and delivery is even better. but if I'm buying an ny strip, I want to see all the choices and pick the one that looks best. similar for fruits and vegetables, I don't trust the professional shopper to evaluate ripeness on my behalf. some things you just have to do yourself.
Database is basically just ab abstraction to help you ingest and query flat files on disk.

If you skip that and do your own ingestion and querying...you just have a built-in database?

This might have some performance shortcomings, but given maturity of caching these days, you can probably just add caching layer in front of the inefficient query engine when the needs arise.

I see that someone answered, but the cultural feel is that jail time is anything from a few hours to a few years for reasons that could include public drunkenness, assault, prostitution, or just awaiting trial, it's kind of ambiguous what it means when someone was in "jail", but it could really be no big deal. Most cities or towns would have a jail.

Prison is a bigger deal. A prisoner was convicted for something unambiguously bad, and there is this cultural expectation that they have become somewhat hardened or institutional in prison. A state or Feds would run a prison.

While I've known people to be in jail for longer sentences than prisoners, the expectation is that prison sentences are much longer.

I'm speaking only to the social meaning of the two concepts, which might help to understand the underlying understanding that Americans share about this difference, but the actual legal realities are no doubt quite different. Most of us are pretty naive about our legal system.
Should drivers also be required to wear helmets? Driving a car is itself unsafe, motor vehicle accidents are one of the leading causes of TBIs.

I honestly think: "Nearly all of them."

We've seen some significant exercise of power, but the underlying legitimacy that gives rise to power is severely eroded. So I am not at all sure that the various institutions have come out of this ahead.

Only in their unification against Russia have I seen an increase in organizational capacity.
What do you suppose happened to the rest of skateboarding that pushed it in the opposite direction?

Watching the olympics this summer, it was amazing to watch the street skating events with none of the competitors wearing any sort of protective gear. And it’s not like they didn’t need it either. They were getting wrecked in falls to the point where some of the couldn’t even finish the competition.

It was nuts watching it, since my last exposure to the sport was from the 90s where Tony Hawk would be padded out to the nines while standing around giving an interview by the side of the park.

What is going on that made helmets so uncool that you wouldn’t even wear one if you knew you were going to fall on your head?
Those people aren't riding bikes 8-10 hours a day, 5-6 days a week. If they can't see the difference then maybe they're better off without a pedicab, I would be afraid to deal with customers who were that smooth brained.

The "must wear helmets" advocacy is never focused on conditions or nuanced ideas about when it is OK not to wear helmets.

Instead, it is focused on make people feel as afraid of biking as possible. Literally all these debates are focused on making people afraid no matter of what conditions, speed.

Interesting find. Although this doesn't mean guns prevent burglaries just by mere presence. And if anything it ends in bloodshed because thieves get shot at upon a breach and it's not necessarily a safer scenario.
What a silly thing to stay. Let me just ignore that and explain why Berkshire works. It's possible to beat the market because it's possible to buy $1 for $0.95. That's the whole trick. It takes a lot of work, a lot of smart people, and you have to make big enough deals to cover the cost of paying the managers, but yes, these opportunities exist and they are abundant. The real mistake is thinking that the market is a bunch of random number generators with no rhyme or reason to it. But no, there are no guarantees--the SPY doesn't come with a guarantee either.

Their angle was health equity in the context of global warming and how it impacts different populations to various degrees. That’s a common trend in global warming related issues. Their argument is fair enough.

My issue with the paper was specifically with the projections they made, which extrapolated the effect on sleep caused by the weather all the way to effects on a 50-year interval caused by warming trends. But by the authors own admission people can physiologically and technologically adapt — at least partially — over long enough time periods. To be frank I think it’s a way to make a compelling headline. They have the statistical tools they have, it would be incredibly hard to account for long-term adaptation, and so they come up with some statistical estimate of the long-term trend. I see why they did it, but from a readers perspective it’s okay to be critical.

Got Honda Clarity PHEV since 2018. Loving it so far. It is 48 miles E range. I need ~36 for round trip daily commute. Charging at work is free. I remember only fuel up only 3 times in 2019 with the 7 gallon gas tank. Normal fuel up is 5-6 gallon only as it has a very small tank. But the Hybrid range is supposed to be 350 miles.

I also just installed solar at home. I expect the next family car would also be PHEV suv to replace the 16 years old minivan. Other than long trip, I don't expect to use gas much, maybe just once a week to oil up the engine for a few minutes.
CRC32X works on 8 bytes at a time and has a throughput of one invocation per cycle, whereas the SIMD operates on blocks in parallel (the chromium code does 64 bytes an iteration, with a lot of instruction-level parallelism too). Theoretically M1 could have thrown more silicon at it to allow more than one CRC32X invocation per cycle, but that's not very useful if you can achieve the same with SIMD anyway.

Because it's well known enough. 200g is the heavier end, sure, but 100g seems pretty light for a wristwatch anyway. The Seiko 5 is one of the lightest watches at about 70 grams, and that thing is tiny. That's to say, the Seamaster isn't really much more heavier than others, unless you're going for some mickey mouse watches.
Worst part is the utterly absurd shortage means RE is never going to meaningfully dip for any period of time without serious structural reforms. The focus on interest rates as the main RE driver is almost completely cope and I wish I could believe it.

Low-rate mortgages certainly aren't helping, but they're "not helping" in the same way that hucking an armload of kindling into an already-raging house fire is "not helping".

I'm cautiously optimistic that societal unrest from this will eventually forcibly neuter local zoning controls but short of that we're just going to keep subsidizing demand and kicking the can down the road as if people don't need places to live.
> Then you probably don’t see value in any form of cryptocurrency. I do, because I think collective agreements are at the heart of how society functions. Fiat money is a collective agreement that works by the backing and enforcement of a central entity (government). It’s at least interesting to me to experiment with a collective agreement that does not have to be backed or enforced by a central entity (bitcoin).

The main problem with crypto is that it does not work like that. Society demands way more than mere vague "collective agreements" in order to function. Society relies on debt transfers that preserve value between transactions. It expects value to be stored and also stable and reliable enough in order to enable deferred payments.

Crypto provides none of that. Worse,crypto proponents explicitly praise crypto's inability to remain stable even in the short term, which manifests itself through an expectation of ever increasing price. You simply cannot portray something as being a kind of money and at the same time praise it for it's "get rich quick scheme" nature.
That happens with plastic because that particular material is usually not economical to recycle (at least as long as the industry is able to externalize some important costs.)

I don't think you can say the same for batteries. There is valuable and scarce material contained in batteries, and it seems likely that someone will find a way to make it happen.
You skipped Pinochet. Thoughts?
Weird, I talked to the guy who invented the crypto scheme for ZIP and he said he invented the CRC algorithm for it as well. I wonder if there's more backstory there.

Edit: He invented the crypto not the CRC, which Phil Katz was already using.
• You still have NOx emissions, no matter what fuel you burn.

• PHEVs have (pretty much by definition) smaller batteries, so they discharge/cycle more of their capacity, wearing down batteries quicker. They're also less convenient, because they have to be plugged in more often and charge slower (if you don't plug them in daily, they're just overcomplicated ICE cars).

• A pure electric drive train is pretty energy-efficient (80%+ Well-to-Wheel efficiency). Combustion engines are only about 35% efficient (and it won't get better: there's no room to use the heat, and you can't avoid generating heat in a combustion engine). It's already bad even if you have perfectly efficient fuel synthesis. We're not near having too much electricity to waste.

• There's still an engine and a gearbox to maintain. These are mechanically much more complex and inherently more fragile than an EV power train.

• Most PHEVs on the market have weaker/laggier performance than BEVs due to having a smaller battery that can't deliver high peak power, and having only one electric motor due to sharing a power train with ICE.

Modern fast-charging BEVs already work great. They have effectively infinite range if you charge 20 minutes per 2-3 hours of driving. That's entirely within reason, and only about 10% slower than pee-in-a-bottle road trips.
