Density has a limit. It's easy to postpone the problem by replacing 2-storey houses with 20-storey high rises, but it won't work for long. Once enough people move in and demand catches up with the supply, you're back to square one, but with much less private space for everyone.

Decentralization, on the other hand, is limited by the supply of land, that is fairly plentiful in the U.S. And it incentivizes taking care of your property, saving and paying off your mortgage (other than just giving money to the landlord). It would also create local jobs for owner-operated businesses related to construction and infrastructure maintenance, instead of corporate drones maintaining corporate-owned apartment towers.

Is going out with butterfly nets to catch some bats a common routine activity among virologists? I'd say if not then the proximity of the research lab to where any bats can be found is not of much relevance - if needed, any bats can be obtained, but they are likely not the most definite factory for locating a major research center.
I'm afraid the authors are overclaiming here, because they keep talking about "microarchitectural side-channels" when they really mean timing channels induced by non-constant time execution being dependent on secrets.

Unfortunately micro-architectural side-channels are much, much more than leaking information through timing of victim code, and I thought by 2021 this would now be widely known. For one thing, Spectre variant #2 can allow attacker processes to inject speculative information leaks by polluting the BTB to induce essentially any speculative behavior you want. That renders all compiler-based mitigations basically ineffective, because an attacker can just bypass them.

There are other microarchitectural leaks like L1TF that allows (on some unpatched, unmitigated CPUs/kernels) the ability to speculatively read all of L1 cache, regardless of privilege level. Let alone speculative attacks on the kernel aimed at reading physical memory, which bypasses any in-process you could think of. And of course, this paper doesn't address the fact that memory access patterns are not affected, so the classes of attacks that reverse address translation and ASLR are on the table. I didn't read the paper in detail, but there's always the problem of mis-classifying "secret" data and not applying mitigations everywhere.

Unfortunately, the authors misuse of terminology will cause this paper to be misunderstood. It has much, much narrower applicability than it would appear. It only applies to specific kinds of timing channels. This might be worthwhile to apply to codes like crypto, but honestly, those need to be designed much more comprehensively now, rather than just applying a compiler analysis to the problem.

Pure natural uranium metal which is not enriched, and is in bulk form, is not a particularly real hazard, unless ingested or inhaled, which would require smaller pieces or powders.

The "unlimited" thing became popular in California in part as an attempt on behalf of companies to avoid having to issue payouts for accrued time off to employees leaving their organizations.

Yeah we came home with some plate titanium, giant sheets of memory foam that got repurposed on our boat, we bought a trailer designed to haul bar steel, then converted it into a canoe trailer for the local boy scout troop, my dad would buy brass bar stock and turn it into POG slammers on his metal lathe that he also got at Boeing Surplus. Just acres and acres of weird cool stuff.
This again appears a system issue, not workshop issue. In a lot of the statements I have seen against the programs on offer here in Aus, were from people incorrectly assessed as being appropriate for sheltered workplaces. Appropriate medical assessment/intervention/care could result in a few instances of people being assessed job capable outside of the ADE but this in itself is a fault in a system that has one option of being ADE employment.

The discussion around it seems incredibly emotional to purposefully distort the opinion of people that ADE/SW are sweatshops or some Dickensian nightmare. I guess profit driven societies have taken advantage of it, like they have with the jail systems, education, law enforcement, military, healthcare...

There’s a big difference between Goodwill and Salvation Army. Salvation Army runs thrift stores to raise money to fund their homeless shelters and disaster relief efforts - thus they are generally staffed by volunteers. Goodwill’s charity is … running Goodwill stores. That’s it. They don’t donate money to anyone. They in fact pay their store employees below minimum wage, under the theory that they are providing “job training”.

No. You're confusing group outcomes with individual ones.

To avoid the emotion of racism, you can look at all Americans instead. Average income in the US is $30,000/year. Is it wrong to teach that to kids? No. Does it cause them to fatalistically assume they can't earn more than that because they're unlucky to be American? No. Each individual kid might not be one of the destined-for-low-wages people.

> but in order to be helpful, I try to answer Y directly and honestly, and then point out my concerns, describing my presumptions.

This works fine as long as Y actually does have a simple solution. Often it does not, and already the question for Y is really weird, but once you hear about the X you can give a quick and simple answer.

That said, sometimes X is really really complicated. But even in that case it'll help anyone you are asking if you quickly outline X in a short sentence, just so the one you are asking has enough context.

(I have been on both sides, but more often then not the simple X was missing from questions was really strange Ys. Though I also have asked for Ys (and even outlined the X) and have been annoyed by people who insist that I should do something else, and describe my X in more detail, but when I do, they can't answer either, because the X really complicated and Y actually was a valid attempt at solving it).

> but it would struggle to meet global demand.

Probably correct. I guess meat consumption should go down.

However as someone who has worked on farms and even studied farming at least here in Norway there is plenty of room for increasing meat production from traditional farming, it just isn't economically viable in most cases.

I personally could agree to see meat prices rise 10 or 20% overnight if I knew the price difference would go to the farmers and especially if more of it went to the ones who use their resources reasonably.
> and only one of the three F-35 variants has VTOL capability.

But they all share the same airframe hobbled with the tradeoffs for VTOL. The F-35 is a great example of trying to do a good job at everything instead of focusing on one thing and being great at it. The end result is it ends up being uncompetitive.

Ironically making a super expensive super complex weapon was a mistake the Germans made in WWII with their tanks. The Tiger tanks cost over $200000 each and took forever to build. They were plagued with reliability problems. The American Sherman tanks cost about $20000 and were mass produced. The Tiger was terrifying and easily won, even outnumbered, but the ability to deploy the Sherman quickly with enough numbers was far more effective. So I find it ironic that the US basically forgot their own lesson there with the F-35.

I tried to switch to Target, especially for standard household supplies, but they seem to be actively pushing people away.

- they killed their subscription service (last year?)
- laundry detergent may or may not be taped (they at least bag it), leading to spillage
- they use the same flimsy tape for all of their packages
- they stopped using any sort of package space filler (I really liked when they were using long sheets of paper - makes me less worried about plastic waste, and we could give them to our son so he could color on them)
- you need to use their app for curbside pickup (Home Depot does this right with the ability to do it with or without their app)
- inconsistent availability of items for shipping

It's easy to meet their free shipping limit, and it's nice to have the option to pickup from a local location, but unlike some retailers, I feel Target would rather you either shop in their physical stores, or go somewhere else.
It won't take much water to support more people, and adding more people might even reduce water demand. Getting rid of old fixtures with née construction drastically reduces water demand. Replacing single family lawns with multi family and shared lawns typically allows far more people to live on the same amount of land and at the same time use less water. Even as my town's population has grown, water use has dropped:

PDF, page 25: https://www.documentcloud.org/documents/20484267-2020-annual...

The bigger problem is water supply reliability, and that's going to need some serious attention whether or not new people come.

The water rights system in this state are absurd, and we use water in terrible ways because of it. We need to reign in the farmers, who have been abusing aquifers and living without thought for the next generation. And we probably need to start taxing water rights, based on the water rights value.
The title is on point. I know a Q'er, they lack basic abilities for reasoning, evidence and instead of doing any sort of hard research they simply trust what their authority says. Which is quite literally a guy on YouTube whom fabricates information. And group chats filled with conspirators and scammers looking to take advantage of them (buying gold/silver at its highest price). We now have cults of information where people intentionally go against the truth because they believe otherwise. If they don't want something to be true they simply say it isn't and turn around pushing their conspiracy. They know they're doing it, but belief is stronger than fact.

These individuals are a result of the western worlds terrible education, devout religion, 24/7 news networks being allowed to lie, and lack of action against forums like 8ch.
Well, you have successfully demonstrated that an strawman plan that nobody would ever dream of implementing wouldn't work. That isn't hard and I am not sure why you put so much effort into it.

San Francisco is a horrible example because it notoriously does really bad at density. Then you halve that density to make it even worse, which will of course force massive problematic sprawl. This alone makes the rest of your long comment pointless as you spend the whole time talking about the problems caused by running out of space due to your low density.

In fact, all of the challenges you've listed are easier to solve with high density cities.

Higher density cities have less water use per capita, so they make it easier to supply any given population level with water. However, I don't think California can support 100mil without large desalination projects.

Higher density cities use less power per capita, plus lower transmission distances reduce upkeep per capita.

With waste management, again you get higher efficiences with higher densities.

Higher density cities mean that you have more room for green space and recreation areas and they can be situated close to the people who use them.

Sure, those who find nature and wilderness attractive will find denser cities less attractive... but those people already find them unattractive.

I know that CA (LA, SF, SD) housing has always been expensive but it seems like in the past 20 years or so it’s become cumbersomely so. Unless you rode up on the wave of raising house prices through those years (presumably, mostly boomers, or you’re already ultra-wealthy) buying a decent single family home is out of the question.

But with the boomer generation approaching EOL (sorry, a bit macabre) does anyone think prices will have to cool a bit as supply slowly starts to trickle up a bit? Or will that just attract other wealthy people from elsewhere into the market? The current price trend can’t possibly keep up at its current pace or no one will be able to buy…

How do you propose to gain equality? You can't force inherent ability into someone. Perhaps what you want is flat wages for all jobs, including unemployment?

Flippers buy from Goodwill and sell items on eBay and Amazon. That is why the prices are so high on jeans and other stuff that might be designer clothing.

Buying electronic stuff is kind of iffy. I bought mice and keyboards and cleaned them up and they worked. Bought a radio with an extension cord and it worked with some cleaning. I have appliance repair books in my basement in case I have to repair things. I could make money buying broken toasters at Goodwill and selling them on eBay after cleaning them up.

I donate cash to Goodwill because they have a program to give disabled people jobs.
Hmm. I'm likely guilty of "wishcycling". Though the article and comments below make me not sorry for it.

If I'm donating to Goodwill to create jobs, sorting waste for valuables is a job.

If I'm donating to Goodwill instead of trashing; then at least if there was a surprise niche of eBay buyers for the body of a vintage toaster, there is some possibilty of reuse. Like old clothes; I wouldn't donate a sock with a hole in it -- oh wait, they shred 80% of fabric and sell it was insulation anyway, the hole doesn't matter.
Lot of comments here suggesting that lack of economic utility is to blame for the Amazon’s deforestation. While maybe true on an immediate basis, this overlooks the fact that 1/4 of all western medicines are derived from rainforest plants. Moreover, of the 3000 plants the US National Cancer Institute has found to be active against cancer cells, almost 3/4 come from tropical rainforests [1].

I don’t even think we can begin to quantify the losses we’re suffering as the Amazon is depleted. But I’m damn near certain the economic utility of logging and cattle ranching pale in comparison to the valuation of the drugs we’ve yet to discover in these forests.
