If you spend enough time in a sensory deprivation tank, you will usually start experiencing abstract thoughts and sensory hallucinations. Dreaming is likely similar in that it's just the natural result of a few moving parts:

1. An eager sensory network with no inputs can introduce phantom inputs into the network, which can evolve through feedback loops in networks not being stimulated by real sensory phenomena

2. The brain and body's tendency to actively "simulate" its internal representation of the world, by creating mental scenarios and then playing them out.

When you throw a baseball, your CNS & muscles run simulations which adjust your motor neuron activation profile and the way your muscular cells function based on feedback from the brain about the success of the action.

When you practice a speech, you visualize the place you will be delivering it, visualize the audience and their potential reactions, so that you can plan accordingly. This is another kind of mental simulation.

Dreams might be the same thing, generating sensory feedback loops from brain activity resulting from memory organization and compression during the sleep cycle, simulating a world and then running through the simulation.

This can greatly increase an organism's survival if the organism's entire life revolves around finding food and avoiding predators / catching prey. While they are hidden and safely sleeping, animals are still able to "train" themselves completely unconsciously.

Seeing as how evolutionarily useful it is, I'm not surprised to see it crop up in multiple kinds of brains and would be very surprised if advanced aliens do not dream as well.

Pure Swift for the new apps. We freak out when we see @ObjC or NSObject usage in our codebase. On a long enough timescale when Apple converts away from using Objective-C under the covers, our code will not need any modification.
Somewhat, though it's also a lot easier to build large radio telescopes because they're mostly a giant metal structure which is less specialized than other projects so it's lower cost compared to most scientific instrumentation which is nearly 100% bespoke for whatever instrument is being built.
> I believe it's fundamentally impossible to test for consciousness. You can't know if it feels like something to be any other thing but yourself.

I used to believe that too, but it turns out that consciousness can interact with consciousness.

E.g. find someone you love and trust, sit facing each other, hold hands, stare into each other's eyes, and breath in synchrony. For some cases nothing really happens in other cases... shared subjective experience.

> The domain of scientific knowledge is completely cut off from subjective experience.

Shared subjective experience is still subjective.

Amen. I've known people who got through Google's interview process, but even then the response is "Great job, we'll let you know within a few months if there's an opening on a team you can join."

Not a great response when you're graduating soon and you've got concrete offers from other companies that will expire.

Weaponizing children can go in both directions. Isn't it abuse and harassment telling children that they're doomed, that they have no future, that earth will be ruined in 10 years?

If crime increases in the neighborhood, do you tell your children they're going to die? No, you tell them to be careful, to follow some simple, easy-for-them rules, and that things will be fine.

This is why you should always construct paths in particular and URIs in general using your languages' path APIs instead of string interpolation.

That doesn't protect you fully. You still have to check that $myfile is not undefined or "", but it helps with related problems and it tends to arrange the code in such a way that the lack of further sanity checks sticks out a bit more.
Oh, man. I still cherish my original Wired. I grew up in a small town, and it was a breath of fresh air. Openly discussing the hacking of cell phone signals, cell tower changeovers, BBS reviews, and more. And their advertising was nuts, given they hadn't lined up many advertisers they were running their own hypothetical ads for really strange things.

After that first issue, I kept going back for more. I have the first 20 years collected, but fell by the wayside as my kids grew up and stopped selling magazine subscriptions for school. :)

I think your last statement is absolutely on point. If we as a species had addressed climate change when it was first raised as an important issue in the 1970's, it would not have required nearly the same level of upheaval that addressing it today will need. The later we leave it, the worse the upheaval becomes.

Basically the science says we will transition to a zero-emission society. We can either plan for it and have a managed transition, or we can be forced into it by external forces, essentially a collapse (good luck feeding 10 billion people with widespread crop failures).

The earlier we start, the smoother the transition will be. That is basically what all the protests are about, people just want to start the transition already.

Yes, exactly.

She! :D

By the way, is there a gender-neutral third-person pronoun besides the singular "they"? It can get confusing to some people. "It" can probably get confusing too, and I think it is also considered rude to refer to people by "it". I have never used "it" to refer to people. Many languages have gender-neutral third-person personal pronouns. I wish English had something that is less ambiguous than "they" or "their" (I know, context!). Maybe I should just start using "s/he".

In general, the notion of "declaring functions in render is bad for perf" is a result of several things:

- Declaring functions (especially arrow functions) _may_ have had a more noticeable cost in older JS engines

- Misunderstandings about how React's rendering works. When a component renders, React recursively renders all its descendants by default, regardless of whether any of their props have changed or not. New prop references only matters when you are trying to optimize perf by skipping re-renders based on prop reference comparisons (ie, `PureComponent` and `React.memo()`.

- Highly aggressive lint rules, such as the AirBnb ruleset, which include the "no arrow functions in render" rule as a warning or error.

As this post demonstrates, declaring functions isn't zero-cost, but in general the cost is meaningless and it's not something that should be avoided. Micro-benchmarks need to be taken with a grain of salt, but it's nice to have some actual numbers to look at.

A perfect brain simulator could answer many questions, but it could not answer the hard problem of consciousness. Science is all about objectivity, but there's an element of consciousness that is inherently subjective, and that part - the part the hard problem deals with - is not objectively measurable.

Huawei Billionaire Dangles 5G Secrets to Create a U.S. Foe
In comparison to nearly any other tenant, they are quite large and also structured quite differently. Other large tenants put similar pressure on tenants, with the clearest example I can think of being anchor grocery stores in strip malls.

The issue is not that landlords can't relet the space, but in the additional cost and the lost revenue of doing so. WeWork has large blocks of space, and in many cities, multiple locations within a single submarket or adjacent ones. If WeWork decides to go dark, that's a significant block of space coming to market, which will drive down market rates. Landlords know this.

The other challenge is that there may not be a prospective tenant willing to take the amount of space that WeWork has, meaning a lot of CapEx to split up the space just to make it marketable. WeWork's buildouts are expensive, and they likely will not work for many tenants, so there will likely be significant costs to the landlord to get new tenants into the space.

There's also a good chance that the spaces WeWork leases may have been hard to lease in the first place. There are reasons why you'd want to take another tenant as opposed to WeWork if you're going to be getting the same facerate for the space.

>There is nothing WeWork is doing that a small Landlord cannot

Yes and No. For an individual WeWork location, your correct. At that level, it's more of an operational concern which the landlord could potentially take over. However, you need tenants and those tenants are attracted to WeWork, not the landlord itself. WeWork has the brand that brings in the leases, not the landlord. We've yet to see what happens when a WeWork location goes dark. Yes, the landlord could just take over the day to day and cut out the middle man. But it's not clear how the tenants themselves would respond to that.

The other side is that landlords don't want to operate and manage these short term leases. It's the reason why there was Regus before and why WeWork took off. The thing is that Regus wasn't really a desired tenant. WeWork has been a darling, but the tides could change quickly.

> The lie is that it's possible to somehow extract Southern culture from its racist roots, as if slavery and its legacy can just be ignored and set aside as not really pertinent, when slavery was as foundational to the South and its culture as anti-Semitism was to the Nazis.

And yet we do not hold cultures of the world accountable to their roots. Many religions and cultures of today stem from primitive patriarchal beginnings. And just as many have people within who hold these backwards views (anti semitic Palestinians, racist rednecks, Post-Apartheid racism, etc.)

As soon as you generalize the people of a culture and make assumptions about them separate from the non-controversial aspects of the culture, then that is when you yourself need to question if you're being the prejudiced one.

Battery production doesn't seem to be the bottleneck in EV production a lot of people seem to think it is. The major battery companies (LG Chem, Panasonic, et al) have all been ramping up to meet the demands they've been contractually asked to meet, and we generally haven't seen shortages or massive price spikes in either direction.

The only EV producer that's outright complained about battery availability is Tesla, and it's very easy to wonder how much of that was marketing spin to cover other production issues (and the accusation of the traditional car manufacturers that car production is hard and has huge startup hurdles), and maybe even PR/marketing spin to their own investors to explain insourcing battery production (building the "gigafactory") rather than partnering with an existing battery manufacturer.

Tesla probably has scaled faster than most other car companies, but yet it has also scaled much less comparably (to say Renault or VW just signing delivery or plant contracts in partnership with existing battery manufacturers rather than building their own factories from 100% "scratch").

I'd love to see a better analysis of the battery market right now. I'm betting the catch-22 that car manufacturers don't feel a lot of consumer demand for EVs has more on bottlenecking EV production than batteries in the current term.

This is excellent! Congratulations to the Purism Librem team for having a privacy vision and all the follow-through to create the phone. I'm buying one.

If you ever ask yourself "what can I do to improve privacy?" then considering trying the phone. The software is open source and there are plenty of areas for ongoing optimization, including subsystems such as security and graphics speed, and apps such as email, calendar, contacts, etc.

I'm not affiliated with Purism; I'm a big believer in the privacy goals and also in the team for their successful launch of a version 1 product to market. Kudos!
Yeah, trail runners certainly could take a tumble, also. I see plenty of them and I'm amazed at their ability to avoid injury on all the rocks on the trail.

I'm a primarily React-based developer, but have taken to using Svelte on side projects. Don't get me wrong, I still like React, but Svelte is phenomenally easy to get started and wrap your head around. I've started suggesting it instead of React to people looking to learn front-end JS.
That's why there are experimental controls with different gas mixtures that measure the greenhouse effect of the CO2 and the effect the glass independently.
Climate is not static.

For example permafrost thaw - we have no idea how widespread it is. The areas we do observe have a valid, natural explanation for thaw via gas cavities. Some of these cavities get enlarged thermal-erosional piping, which can expand the cavity due to seasonal temperature changes, which can make the cavity large enough prevent re-freeze.

This isn't magic. It's science.
You are missing herd-immunity.

A vaccine that only conveys, say, 20% protection to individuals can still convey ~100% protection to a group by tipping disease story from "spreads exponentially" (average_new_infects_per_person > 1.0) to "fizzles out" (average_new_infects_per_person < 1.0). That's called herd immunity. Even a modest minority of anti-vaxxers can sabotage herd immunity, leaving the rest of us with only the vaccine's individual protection margin.

That isn't characteristic of the kind of accelerationism as the blogosphere ideal in the OP.
This is a common misconception about evolution and natural selection [1]. Evolution doesn't have an "arrow", or direction, and it doesn't necessarily lead to any kind of improvements at all. Natural selection merely means that the least healthy individuals of a species will be less likely to pass on their genes. Intelligence likewise will not necessarily be put to any kind of use at all.

The evolution of human intelligence is still a delightfully big, open question in science, but the current thinking is converging on it being, well, as Bob Ross might have put it, a "happy little accident". Researchers have been able to track the development of the human brain through the varying sizes of a hole in fossilized hominid skulls [2]. Brains are massive caloric sinks and require a lot of food, rich in animal fats, to be able to develop. [3] Meanwhile, just a short time ago in evolutionary terms, humans accidentally developed the ability to digest milk into adulthood [4], and we got overall bigger, stronger, and healthier -- but our hungry brains also got a new source of nutrients.

The jury is still out on exactly what evolutionary advantage our brains confer, if any [5]. So, it is possible that human-level intelligence is not an evolutionary advantage at all. There are after all numerous species at the top of their respective food chains, evolving much more slowly, that could be considered successful in evolutionary terms. And, given the caloric requirements of large brains and the unclear advantages that they produce, they could maybe be viewed as a disadvantage.

If we were to view brains as, well, a kind of tumor of sorts, that will simply grow and develop depending on caloric availability, then perhaps humans developed agriculture because our brains were hungry and civilization because our brains got bored, and all of this was only possible because we accidentally developed the ability to digest lactose as adults, and none of it is a necessary consequence of evolution at all.

This btw is one of the major components to my favorite answer for the Fermi Paradox.

Lay concrete
If you eliminate US/EU production of CO2, atmospheric CO2 levels would rise 24% slower. If you added in a carbon tax that it levied on imports from countries that don't implement an equivalent system you can bet that China would lower its emissions too. If you're very fancy you can also offer to install alternative energy in foreign countries at cost price.

I don't think I understand this. Take two scenarios. In both cases, I'm 22 years old, just exiting college, and starting my first job.

In scenario 1, I start working at a 1000 person company that offers insurance benefits. I sign up for their plan, and my employer pays for nearly all of it.

In scenario 2, I start working at a tiny company that doesn't offer insurance benefits. I find an individual plan (coincidentally from the same insurance company used in scenario 1) that suits me, and sign up for it, paying out of pocket.

The total amount paid to the insurance company in scenario 1 is, as is typical, lower than in scenario 2.

In both of these scenarios, the insurance company doesn't know anything about me. For scenario 1, sure, they might know the mean and variance of expected health costs of the 1000 people already at the company, but that does not extend to me. They cannot assume I will conform to the rest of the group. I am new, and an unknown, and they do not know how I will affect those statistics. For scenario 2, I'm just another independent signup. I might have health care costs in line with the average of all of their beneficiaries, or I might be an outlier (on either end), or something in between. But that's the same as scenario 1.

This feels like it has nothing to do with risk assessment; this is just a reflection of the company in scenario 1 having greater negotiation power because they're representing 1000 people, versus you just representing yourself.
