Yup, but the situation is even better than that!

https://en.wikipedia.org/wiki/John_Stapp#Work_on_effects_of_... shows that 50 gees is survivable, at which speed you need 120 ms and 3.6 m to decelerate from 60 m/s. Not pleasant but still safer than a car crash. If the airbags inflate before you hit the ground your terminal velocity is much lower, decreasing roughly in inverse proportion to your hydraulic diameter (√(2mg/ρ/A/Cd)), so a 1.5-meter-radius cocoon of airbags around you will cut your terminal velocity to about 20 m/s, at which point you need 40 ms and 400 mm to stop safely. For this you need something like 4-12 1.5-meter-diameter airbags, 7 m² of surface each; at 20-μm thickness that's 140 cc, and if it's mostly something like gel-spun UHMWPE fiber or polyimide film, it's also about 140 g each, so 0.5-1.7 kg total bag weight --- plus conventionally 2 kg of nitrogen per airbag in the form of 3 kg of sodium azide, which is another excellent reason to perform the inflation well before you hit the ground, so you can use atmospheric air instead.

Suppose you weigh 100 kg. To stop you at a safe 20 gees max when you hit, the bag needs to exert 2000 kg max force or 20 kN, so the pressure in a bag acting over something like 1 m² of your body needs to peak at 20 kPa, about 0.2 atmospheres or 2.8 psi. Approximating hoop stress as ½Pr/t we get a bit under 400 MPa stress in the bag, too much for unaided polyimide but an order of magnitude lower than what UHMWPE fiber can handle. So you can make the bag thinner than that, lowering the weight further, perhaps to 40 g per airbag. There are whiplash shock loading problems conventionally handled in automotive airbags by generous safety factors that can be reduced by origami design and judicious addition of thicker compliant material like nylon.

A 30m airbag would need to be 20x thicker and would have 400x as much area, so it would weigh 8000x as much, 320 kg. This would indeed be unwieldy for a backpack.

You can closely approximate constant deceleration by connecting the airbag under you with other, more voluminous airbags on the other side of you, just as a car tire closely approximates constant pressure when traveling over bumps in the road. But it's not necessary; what's necessary is acceptable peak deceleration and, probably, minimal jerk. It's true that constant deceleration is the best case of minimal distance and time for a given peak deceleration, but even linearly increasing deceleration, like from a Hookean spring, only doubles the time needed to stop when holding the peak deceleration constant, thus multiplying the distance by √2.

So, you see, all the materials and mechanisms necessary are already available, though only in the last few decades. There's no technical risk. It's "just" a question of engineering the thing to not kill people all the time when it fails, based on experience with what the deadly failure modes are. It'll require a lot of work and many deaths, but if people put in the work, it will definitely work.

Let me know if I got any of the calculations wrong!
> Nurses in Boston have been striking for almost a year

I'm surprised more haven't been. Nurses are being outright abused, but that doesn't change the fact that nurses are being asked to travel great distances to help with staffing issues. The whole situation in nursing is a huge mess right now for a lot of reasons.

> I've seen one instance of calling in the national guard recently

you should be paying more attention to the news, or possibility looking critically at where you're getting your news from since it's not serving you very well. I don't know which one you heard about but your list should include Washington, Georgia, Ohio, Oregon, Maine, New York, and New Hampshire. New Mexico has also called in the national guard because of omicron, but they want troops acting as substitute teachers.

> and ventilators are no longer the preferred treatment protocol in every case

That doesn't mean they aren't being used by covid patients or that hospitals aren't still struggling with a shortage of them. see here for example: https://www.kansascity.com/news/coronavirus/article257168037...

> I haven't seen a single effort to literally build more hospital wings with ICU beds. Have you?

Yes I have. Most hospitals don't want to add entire new wings full of beds because covid isn't going to be like this forever, but in just the last few months here are some examples of hospitals doing wherever they can to add capacity:
https://www.courant.com/politics/hc-pol-nursing-homes-covid-...

https://www.bmj.com/content/375/bmj.n2775

https://www.wpr.org/mayo-clinic-puts-hospital-beds-ambulance...

https://www.sacbee.com/news/coronavirus/article257323822.htm...

This is on top of all the beds and overflow centers hospitals have been adding over the last two years. It's not that every hospital is waiting until they have people dying outside their doors to start adding beds either. One of the best US hospitals for heart surgeries is just outside of Chicago and they've renovated parts of their old partially demolished hospital building to keep on standby so they can handle covid cases in case they get overwhelmed like so many others have. It's a pretty smart way to gain some extra ICU space while keeping costs down.

Your facts are just very wrong or very incomplete. I recommend looking into this stuff a bit more using new sources.
> I wish more backup tools gave you some kind of assurance in the marketing materials that they've been validated on, say, 10TB.

I'd wish that too. Also, I'd like to pay for a backup tool, since it's so critical, so that I can get a sort of support, but I have found issues with many of them.

I must say that, with my small population (N=1) for testing, it was hard for me to settle on a backup system. I tried duplicity, then I tried borg, then I used duplicati. I had considered attic and restic as well, but I don't remember why I didn't choose them right now.

I experienced issues with most of them and I reverted to duplicity. With borg, I had a persistent issues where backups would stop and said something like "backup destination is newer than source" (I forgot the exact message, but happened multiple times across versions). Duplicati seemed a very large and complex codebase, and periodically stopped working, mostly because dotnet runtime issues AFAICR.
I just got up, walked into my office, and tried it on a 102, but WAIT doesn't seem to be recognized. I'll try it on my 100 later, but I'd wager the same.

It's not that easy, unfortunately. The problem lies in the relationship between a mind - the system of patterns of connections and processes that constitute whatever it is that allows a subjective experience to occur as an emergent property - and the external world. That singleton which has experience, and the infinite outside which it experiences.

Free will could be framed as unpredictable behavior arising from the emergent system itself, where the selection of one choice among many is deterministic, but otherwise indistinguishable from a non-deterministic system to any other mind. This is a plausible scenario that aligns with chaos theory and implies that every mind is a unique occurrence.

The firing of a single neuron can be triggered by quantum circumstances affecting the location and energy of a single calcium ion, and that single neuron can be responsible for radically different states in the meta-patterns that comprise a mind at any given point in time. Even software on silicon could be subject to bitrot, cosmic bit flips, and other fundamentally unpredictable changes. How such randomness affects the system plays into whether free will can exist in this sense.

The idea behind free will is that the mind has the ability to make choices independent of any influence except itself. It's highly probable that minds are entirely abstract, dependent on the physics of its substrate but existing as an emergent result of the particular arrangement of particles and energy in the substrate. If the choices made by a mind are indistinguishable from a hypothetically independent system not dependent on the physics of the substrate, it could be seen as "free will." Is definitely not the religious/supernatural Free Will, though.

If a mind is perfectly replicable - if you can perfectly simulate the state and ongoing experience of the mind bit for bit, - then you should be able to perfectly predict its behavior and state over time. It could be that such replication is mathematically possible but fundamentally intractable. Such a result would mean minds exhibit behavior indistinguishable from free will. It would mean that perfect knowledge of the state of the mind could never be known outside the mind itself - an extension of Heisenberg uncertainty - and simulations would be inaccurate.

The emergent, entirely abstract meta-system comprising the mind and its subjective experience could also be seen as the non-physical soul or spirit. That doesn't make room for the supernatural or magic in the universe. It might mean that divergence from prediction by the outside exists but is vanishingly small. It could also imply high probability of divergence if compute capacity needed for simulation grows exponentially over time and capacity of the mind being simulated. The answers will depend on exactly whatever "minds" turn out to be and the mathematics that govern the phenomena.

I personally think that radical divergence is likely, for no better reason than to think the universe is a much more interesting and weird place should that be true. It would mean that minds will forever be surprising, however much we increase computation and efficiency.
YC doesn’t seem relevant to the situation, it’s just an investor at this point.
> Apple is power (money) and influence for the US, and there is increasing geopolitical tension.

They're an international company. Apple has already demonstrated a willingness to bow to pressure from China and censor apps etc. China is where their manufacturing and supply chain is, and the consumer market in China is nearly as big as it is in the US.

So it seems more of a liability than a benefit in a geopolitical conflict.

the most effect you can have on your eyes can be cause by study. When you have to use your eyes and your brain at the same time. My parents told me that too much video games is bad for my eyes, from my experience, I became shortsighted in the period I had to study a lot and not playing video games.

It has nothing to do with loyalists and everything to do with practicalities. I was responsible for a fairly big project in 2011 and we decided that Python was the language of choice for some of the components. We started out with Python 3... but then soon realized that a lot of libraries and tooling that were available for Python 2 were not available for Python 3. So, we had to convert our code to Python 2 and continue because we had already spent some time with it. In hindsight, we should have picked some other language than this god awful mess. It pains me to see that Python is the most used language today given their history of how they handled Python 2/3.
Hydrogen-air fuel cells and aluminum-air batteries don't need any breakthroughs to work; they're well-understood, proven technology. They're just more expensive than kerosene and, in the case of hydrogen, more voluminous.

To put it differently, the reason nobody is flying across the country today on aluminum-air battery power is not that the existing batteries don't have the range; it's that they can fly across the country more cheaply on a combustion-powered jet.

(I think that will continue to be the case even when the combustion fuel is synthesized with electrical energy.)
Except that IE was never both faster and more battery friendly than the competition.
Python 2 was originally going to be EOL'd in 2015, the announcement for which was in 2008. Only later was the EOL pushed back to 2020. So while it's only been officially "dead" for two years now, the writing had been on the wall for 12 years before that.

At this point it is stubbornness - I know software doesn't magically get ported and updated as time goes on, but I also acknowledge that if no one cares to update the software (or provide a replacement) in a 14-year window then that is on that package's community rather than everyone else. The baseline should not be dragged down to accommodate legacy software.

MacOS removing Python 2 support in a minor OS version bump was the wrong way of handling things, but in general you should not expect it to be available on modern platforms or be surprised at its removal (outside of pledged long-term support e.g. CentOS). And you can still use a VM or something, same as you would use DosBox to run old 16-bit software.
>he way pip assumes that the python interpreter and the python packages that have been installed are locked in a death grip drives me nuts. Even if you don't go full nix-store, could we at least separate those things? Even node gets that right.

On this I definitely agree. Like I said I do think Nix is the right thing to do, I'm just thinking the how could be better.

If you reduce free will to randomness, an electron has free will. If you don't, then you propose that free will is somehow disconnected from physical causality. That is at odds with our understanding of the universe.

True, except that's only been since catalina which is from 2019. While I get that programs can't practically run on a new OS decades later, I don't think we should be okay with such a short lifespan as on macOS.
> There are working examples of such and the code appears to be significantly simpler than the status quo

This assumes Google ships features that are useful to people. But, what do we get in return?

A privacy-invading feature like FLoC which thankfully has been disbanded. And Google even controls specs. Thankfully, due to safari web is free from the monopoly of Chrome. Today some website doesn't work in firefox. Do you think that is good for the web?

I understand the shenanigans of Apple here. They just want to make sure people make apps instead of the website so, that they can egregiously charge a yearly fee + 30% of revenue. But safari does protect the web in some way by challenging Google.
The Game Boy definitely does do that, as a sibling comment also mentions, though I don't remember there being a case about it. My recollection from long ago is that when you turn on the Game Boy with no cartridge inserted, there's just a black box where the Nintendo logo normally is. There's a well-known similar Nintendo case but it involved the NES, and there was a later one with Sony over the Playstation BIOS.

But yes, the courts (or at least the 9th Circuit) have looked down on these attempts to use copyright and trademark as methods of preventing access. Of course now they have DMCA anticircumvention provisions to help out instead anyhow.

You seem to suggest some kind of hidden variable theory for free will: https://en.wikipedia.org/wiki/Hidden-variable_theory. As far as I know they're not particularly popular among physicists, although we haven't (completely) ruled out such an explanation.
Lloyd Center Mall in Portland, OR was in the news recently.

It was at one point the largest mall in the US. And, now is one of the few places supporting a diverse community of young people from around the city. And, also, a place that has become a focus because of the car break-ins that are plaguing the city, depending on what news sources you read.

The owners were going to sell it and people were excited about the opportunity to reconsider an extremely large space in a major urban area. Then, the owners decided to turn it into apartments and condos.

This will save the ice skating rink, and that's good. But, in the COVID era when public spaces are so hard to find, I wonder how that will impact people who don't own their own large houses, and I'm somewhat sad malls are moving in this direction, even though I hate going to them myself.

Sure, the thinnest slices on the highest zoom are going to be misleading. They're also not what you generally will want to be looking at (though they may provide context for you to identify the part higher functions taking a long time or hints about cache contention etc).
So if the only reason people use Chrome is that it comes pre-installed on Android, it shouldn't matter if it's allowed on iOS right? Most people would keep using the pre-installed Safari right?

> A 30% cut for small developers makes a certain amount of sense.

These are the developers you want to support the most in the hope that they don't die before they become bigger and generate more revenue for you. They also don't generate that much revenue for you right now, so overcharging them isn't nearly as profitable as overcharging the big players.

And overcharging the little guy but not the big guy is bad PR. There are a lot of them and they'll spend their lives complaining to anyone who will listen that you're destroying their business and making it impossible to compete against "volume discount" conglomerates.

> Apple instead should've offered volume discounts for "Partners", scaling down to 10% or even less.

So then they lose most of the money anyway because the "volume discounts" go to the people with the most revenue. Might as well lower the price for everyone.
> "The idea that you can crack AGI because you have created a driverless vehicle is absurd."

I don't wish to be disrespectful but its undesirable to give life alteringly bad medical advice on a public forum. Saying hey don't listen to me listen to your doc after you gave advice that would literally lead to a portion of readers to actually die is in a word insufficient.

>They won't exhibit an immune response to COVID spike proteins. From the virus, from a conventional vaccine, or from their own cells' production following an mRNA vaccine.

This is absolutely untrue. Most people who are immunocompromised have an immune system that works poorly not none. They are worse off than others as far as mortality and morbidity with the vaccine and without it compared to healthier individuals but they are absolutely able to develop antibodies and benefit from vaccination.

The CDC says they are 65-80% less likely to end up in the ER presenting with covid if vaccinated and boosted.

https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e3.htm?s_cid=mm...

Immunocompromised people that took your advice would be 3-5x more likely to die if infected with covid and given prevalence will very likely to be infected in the year ahead of us. Please refrain from giving medical advise without first taking the time to understand the topic you are speaking on. It's more important not to spread health misinformation than chat on business and tech.
