Re: "ecological disaster"

I believe this is misinformation, because it assumes that the energy usage is not being well spent - that Bitcoin is a waste - but that assumption could not be further from the truth.

Bitcoin's value lies in its absolute scarcity and immutable monetary policy - it preserves your time spent working in a money that cannot be debased by anyone, ever. There will only ever be 21 million bitcoin.

If your savings is constantly at risk of being debased, not only do you lose purchasing power over time, but you're also incentivized to spend it and invest it as quickly as possible, rather than waiting thoughtfully for the best purchase or investment. You're being forced to have an extra job, as an investor, to even remotely come close to making a good investment. This is assuming that's even an option and that you have access to financial institutions in your country.

Technology is advancing exponentially - it should bring abundance and higher quality of life to everyone in the world. People will get more for less money, i.e. it is exponentially deflationary. With an inflationary monetary policy, where markets and assets prices are supported by the printing of money and will immediately crash if the printing stops, many nations will be forced to print exponentially to fight the deflation caused by technology. In other words, technology should be saving everyone time and energy as it raises productivity, but inflation forces everyone to work harder to keep up.

How can a finite planet support an economic system that demands infinite growth? A money with absolute scarcity solves this by allowing for deflation in prices as technology drives abundance. Fiat and inflationary monetary policy is the root problem driving climate change, and likely many other complex negative externalities.

In addition, I would point out that energy usage is not intrinsically bad. Higher per capita energy usage leads to higher quality of life. The climate issue energy poses is within how the energy is produced, and the majority of that problem lies in the emissions from coal power.

The good news on the energy production side is that a monetary network using Proof-of-Work incentivizes competition between miners globally. As cheaper (or even free, stranded) energy is made available to miners anywhere in the world, miners anywhere else who pay more for energy are pushed out of profitability and have to shut down shop. The difficulty adjustment in Bitcoin mining means that as more miners compete, those paying the most for energy are forced out of the market. This creates a clear incentive for miners to find the cheapest possible energy, which is predominately green and renewable and drives innovation in the space. Cheaper energy is great for humanity. Check out the recent work by ARK / Square exploring this.

Overall, these developments have made me hopeful and optimistic about the future again :)
The counter is what is the point of Btrfs and Linux software RAID when ZFS is better in many ways....

Btrfs is not stable in all configurations. Mdadm and others don't do checksumming, scrubs, health checks, etc as well as ZFS (or at all). That's not even touching on built in encryption, compression, snapshots, boot environments and more.
This matches more with what I remember - that the concern was incorrect usage and replacement of masks was going to create a bigger transmission vector than what the masks prevented. I.e. there was never strong doubt the masks could do something about it rather there was doubt the masks could do more good than harm with what was known about the virus at the time.

Once the amount of airborne transmission and asymptotic carriers seemed a higher factor in spread than initially expected the consensus on to whether to wear them changed but not the consensus they would help with airborne transition in the first place.

So was the initial advice wrong with current understanding? Yes, pretty concretely so at this point, but precisely because it was data driven advice instead of a retrospective or fear based thinking.
Company I worked for. We built an aerial multispectral imaging system for monitoring seals, polar bears, and other mammal populations. It's 3 high power rugged PCs, semi-affixed in a shock mount case in the tail of a Twin Otter. There's no hangars available at the airbases in e.g. Kotzebue, Deadhorse, Utqiagvik, so it sits on the tarmac and experiences some intense temperature swings.

It's made it 2 winters and dozens of missions so far.

The customer is NOAA and they really don't have oodles of cash to spend on this thing, so it's mostly commodity hardware. Initially we designed this whole crazy insulated case to keep it from getting too cold, but the aircraft engineers nixed it due to fire hazards. The airframe isn't airtight so it gets most of the brunt of the diurnal swing.
With a de-duplicating backup system like Borg, you can keep more backups in the same space. borgbase.com provides append-only and 2FA, which keeps your backups secure.

Richard Feynman in What Do You Care What Other People Think? says something similar happened with his first wife Arlene who contracted tuberculosis. If we trust his account, then it went something like this:

Arlene presented with bumps on her neck and the doctors couldn't figure it out. In his free time Feynman read medical textbooks in the Princeton library, and the first thing in the book is tuberculosis, which it describes as being "very easy to diagnose." Feynman assumes if its so easy and the doctors can't figure it out then it has to be something much rarer, something like Hodgkin's lymphoma. He asks the doctor about Hodgkin's, and the doctor admits it is a possibility.

> When she went to the county hospital, the doctor wrote the following diagnosis: “Hodgkin’s disease?” So I realized that the doctor didn’t know any more than I did about this problem.

After several months the doctors order a biopsy of her neck and pretty easily confirm it was tuberculosis. Feynman concludes that he made a huge mistake assuming they ruled out the easiest diagnosis.
Yeah but this isn't a 9. If it's really that low temp spec, it's gotta be kicking off most days for this and next month in AZ
> Their FAQ on the topics simply says they'll block "medical misinformation" which they define as anything the WHO disagrees with

This seems entirely sensible to me.

> As the WHO has repeatedly disagreed with itself

Unless I misunderstand you, you're saying this as if it's a bad thing. No one's saying the the decision-making processes at the WHO are perfect, but shifts in stance and advice in response to newly available evidence is not "disagreeing with oneself". It's fundamentally how science works.

In fact, most of the criticisms from credible experts have been that the WHO have been too resistant to updating their positions (in the face of the increasingly overwhelming evidence last year that the virus is airborne, for example).

> this is pure authoritarianism. No fact-finding has gone into this decision.

You consider their policy of deferring to an internationally recognised public health body to inform their content guidelines to be an example of authoritarianism?

If so, what alternative "fact-finding" approaches would you suggest?

Because if we imagine for the sake of argument that YouTube somehow had the means, resources and competence to conduct their own rigorous studies and research, in such a notoriously complex field as public health, and used this to inform their content moderation decisions instead of information from the WHO, how would this be any less "authoritarian"?
"The ends justify the means," is an epitaph on countless headstones.

Edit: Here's some food for thought. Tesla was basically forced to admit the display issue because it was so pervasive, and they basically got lucky that their display didn't cause other problems or bigger problems.

Just how lucky was Tesla? We know they're willing to take a gamble. Where else did they cut corners or skimp that we just never found out about? What else might have gone wrong? Automobiles are one of the most dangerous machines on the planet. We've also heard horror stories from former employees about working conditions, too.

People are Tesla fans because they're excited by the image. By electric cars. By the idea. But they're letting their desire to have that image in their head untarnished means they're not going to be willing to accept genuine criticism of genuine failings. Just like Apple, and Linux, and so many other products, it's generated fans who live up to fanaticism.
You're simply coming to the astute observation that any individual HN commenter who may very well be a genius WRT an extremely narrow area of expertise will be just as hopelessly clueless as the average person when it comes to any area outside of their expertise.

Well, take the second link for example: https://austingwalters.com/covid19-vaccine-risks/

1) The chart shown mixes up lipid concentrations for protein spikes from the original cited paper and data

2) R00-R99 coded deaths will always be higher for "new" data. Over time, these are revised and coded differently. So if you look backwards from today, it will always seem like this number has gone way up the last month or so. The author notes this in his post (good), but leaves the original one in its place (also fine, but just be aware).

The author's hypothesis is not supported by data, and the arguments put forth are based on misunderstanding or misinterpreting things.

Also if the fear here is the mRNA vaccines are dangerous, there's always the more traditional Janssen (J&J) vaccine which does not use mRNA.

I had a friend who quit their JPL software job (to go work for a large, bureaucratic software firm) because JPL required such an extensive testing and review regimen before every change that the work got boring for being too slow.

I am very skeptical of the claim that this code was not tested before launch.
There is also a linear degradation of metadata/blockinfo performance (in the order of the number of rewrites) due to the need to check multiple possible locations for the block pointer. In practice this probably just means more RAM utilization but... eh.

Even as a home user, I've become convinced the juice is not worth the squeeze. For serious use, just buy four drives at a time and upgrade four drives at a time. That gives you 4-drive RAIDZ1 in one VDEV and if you want you can expand to a second VDEV or upgrade the capacity of the drives in your existing VDEV.

If you don't want to do four drives at once, you can still use ZFS with 1 drive = 1 pool (or 2 mirrored drives = 1 pool for redundancy) and just manually distribute files over the volumes. No, it won't automatically do it like Unraid but perhaps you can layer unraid over the top somehow if you really insist (otherwise there's also solutions like git-annex). It still gets you far better data integrity guarantees and far better reliability than any available alternatives.

Maybe it is just stockholm syndrome but do you really, really need to dynamically expand your array by an arbitrary number of disks that badly? There is ultimately no way around the reliability question so you can't expand forever and if you're serious about setting up a nice fileserver that'll be reliable for the long run, putting 4 drives in it isn't that bad. And ZFS is no worse than the alternatives on 1-drive or 2-drive scenarios in terms of reliability/expansion. Meanwhile ZFS is far far better than the alternatives (btrfs) in terms of data integrity and reliability.

There is also the possibility of manually doing some weird shit like putting 2 partitions on each disk so you could move one member of the VDEV over to another disk if you expand, if you start with 2 disks with 2 partitions each then you could grow to 4 disks without issue, which would lower the increment even further.
If you ever work on hardware, please talk to people who actually know what they are doing.

Anyone with a six week internship worth of experience would have tested this in an environment chamber.

It’s bad enough when idiot “first principals” MEs and EEs toss this stuff over and I have to deal with it, but it doesn’t fucking reach customers with faults that bad.
I scrolled though a bit wondering that too. Seems that buried in the post is a graph that shows it actually was a dramatic plunge in deaths correlated with the vaccination. I say ‘buried’ because it is surrounded by graphs and text concerned about a relatively much smaller increase in uncategorized deaths. It looks intellectually lazy. Similar stuff has been posted many times and this doesn’t appear to add to the discussion of COVID. The links may confirm anti-COVID biases and confuse laymen, but does not seem likely to withstand rigorous analysis.
My understanding is that once the antibacterial products stop getting used the resistance to them is no longer selected for.

But most hand soap is only antibacterial insomuch as the soap chemically binds to them and the water washes it away.

If Eth2 isn't done by then, then yeah, you might be right. But if it's done by 2022, I think it's probably gonna win, like JavaScript in the browser. Algorand currently has less adoption than Ethereum Classic, and Ethereum Classic has way less adoption than Ethereum.

You're not kidding, they're 8 kHz i.e. ""phone resolution""...

Interesting, this seems to be related to the Bluetooth microphone that they used:

"Thus, we adopted a very small and lightweight microphone placed under the cat’s throat through a collar"

The microphone is described in their paper [0]: "The signal is transmitted via Bluetooth [...] at a sampling frequency of 8 kHz."

Also:
"As a consequence, the actual range of frequencies we could rely on is 0–4 kHz. We expected that the fundamental frequency emitted by cats falls within the range, whereas some higher-frequency harmonics were likely to be cut"

This matches my thinking as well...In general, we are relatively close to breaking new ground in longevity or even aging reversal on multiple fronts...Yet, we are utterly socio-economically, ethically and morally immature for any side-effects that might bring. It's hard to be optimistic about the further divisions this would create in society, and the sheer scale of change that would be required to mitigate the consequences...We are still much more interested in throwing of feces at each other (luckily, mostly symbolically) across imaginary borders, fighting over imaginary tales and dieties and chasing to posses the latest material object which signals success to anyone who can see it, while rapidly destroying our own habitat...I doubt that there is anything that can happen in the short term that could turn things around and make us grow more mature to tackle advancements like this and battle biological and technological challenges before us...Even as an optimist at heart, it seems hard to not have the impression of sliding downwards in recent history / present.

I don’t understand this at all. MISRA C, model checkers and theorem provers all exist to provide some of these guarantees that are, to my knowledge, widely recognized in applications where “safety” actually entails life safety. F* is a very modern tool, I think, developed for precisely these use cases. I’m not aware that the rust compiler is proven or even specified. Avoiding its mechanisms for validating use-once memory isn’t even that uncommon, especially in low-level library code.

That Google is the man behind the curtain here also comes off as weird since they have not, to my knowledge, standardized their own critical infrastructure on Rust.
122° Fahrenheit is not "just" hot, a lot of things will have problems operating normally at that degree of heat.

Like in the area where I life a satellite dish reaching 50°C would be the rear exception. And if the alternative is not having proper internet at all other days, Startlink would still be the better option, even if there are a very few days where it fails during the afternoon of the day.

That's where the devs have to decide whether they're willing to sacrifice some realness for the sake of gameplay. The game director for Doom Eternal has been streaming the game and providing commentary on it, and he talked about how for this game, everything took a backseat to gameplay, even if it doesn't look realistic. For example, if there's a surface the player can break, it glows neon green, but if there's a surface that can only be broken by something in the environment, it glows a dingy yellow color.
It’s not vaccine “deniers”, it’s extreme views like yours that paint them as such.

One of my co-workers got covid, recovered just fine and then continued to wear non-N95 masks religiously. He honestly lived in an irrational fear, especially seeing the fear porn on TV.

I asked him why he was still wearing a mask, and why was he scared if he’s already done with it.

“Oh because I’m waiting for the vaccine.”

…

Putting aside all the hysteria and orange-man-bad, when did the relationship between vaccine/natural-response go away? He was seriously confused about my line of questioning pointing out that he’s already got the natural form of a vaccine.

When did we all forget that chicken pox can be a serious thing to older people, but it’s relatively harmless to children? Once you get it, you’re generally inoculated for life.

So when you have the majority of people behaving irrationally, leading scientists lying and playing politics, how is it anything but natural to say:

“You know what? Let’s slow down for a second, and find out what’s what, because for the past year everyone’s been lying”
Apprenticeships everywhere get underpaid. In Germany, the idealist model for apprenticeships, I remember reading a few years ago that the pay was 2-3EUR/hour...how does that compare with the US minimum wage? I believe they brought in a minimum wage law to deal with abuses but wages in the US are pretty high (yes, even after healthcare...the US has a public health care system that is as large as most in Europe, double places like the UK).

If you slow down aging the percentage of healthy people goes up making the elderly a tiny percentage of the population.

Right now about 80% of men in the US live to 65. If you slow aging by 1/10 so someone at 650 would theoretically be as healthy as a current 65 year old only ~(0.8) ^ 10 or 10.7% of men live that long.

Push it to say 1/100th and accidents are basically going to kill everyone while their healthy, in theory only about 7% of men would live to the equivalent of 30.
I think you're operating from a broken definition of the word "flaw".
I wouldn't mind. Xcode has an insane amount of cruft built up over the years and maybe 10% of its functionality is used by 90% of developers. I think starting over with something that only caters to Swift + SwiftUI development would be a good investment. Xcode can still stay around, but the new thing should evolve to fit enough workflows such that you shouldn't have to download it anymore.

I don't hate Objective C as much as others, but its time is clearly over and Apple should embrace the future it is building for itself.
Drop the union and things get even better. Don't let the poor performers drag the average or top down.
I don't think that's too important. Scaling that much on a single server is economically rather bad and we're talking about mid 6 digits per Server. If it's in any way posse, and it usually is, you'll probably want to scale horizontally. These servers sure exist, but I highly doubt they make up a large share of the market.
I'm not a big Windows Server guy, but as I understand it, in Windows you would use Storage Spaces instead of traditional RAID.

> Deliberately going forward with something in spite of knowing for certain that it's not fit for purpose is called engineering malfeasance, not arrogance.

An argument can be made for both. Malfeasance in that it was a significant and potentially catastrophic engineering tradeoff due to unknown failure modes, and arrogant in that the decision valued company vision over potential consumer safety risks as well as over the expertise of the component manufacturers.
