I always thought it was “raising Cain”, as in the biblical figure who killed his brother Abel.

A quick google suggests that’s right, and the “raising” is in the sense of “summoning”, which makes sense - summoning the spirit of a famous murderer!
Where are these people in the US? They aren’t the 60%+ who are buying iPhones. They also aren’t the ones who are buying the Google Pixel, or high end Samsung Galaxies.
I think David Sinclair's track record of actually producing meaningful improvements in human longevity is zero. The whole sirtuin thing got big funding from pharma and then totally failed. I would remain very sceptical of what he says, as he definitely talks up his own work as high as it can go and beyond.

Personally, I doubt these supplements make any difference. I also doubt that metformin makes a big difference (as well as being poorly tolerated in many people).

This is what comes to mind:

There is one universally beneficial thing and that is exercise.
What exercise? Anything is better than nothing. But doing 150 minutes per week of Zone 2 is probably optimal. Also resistance training. Don't over do it.

Second thing: screening for things that kill you. Manage modifiable cardiovascular risk factors:

- check lipid profile including Lp(a) and ApoB, manage appropriately

- inflammation, although can be hard to improve, maybe dietary changes.

- hypertension

Also do all the screening for cancer: mammogram, faecal occult blood, pap smears.

Take a thorough family history, what did people die of and at what age. There can be clues from that about what needs attention. In the extreme case, there may be a strong family history of cancer indicating need for germline testing.

Other things: Pneumococcal vaccine, shingles vaccine, flu vaccine.

If the option exists, move closer to the equator (mortality is higher further from the equator, as is cancer incidence).

Other comments mention social activities, also very important.
Actually the current REI return policy has a time limit of 1 year. It changed in 2013:

https://www.seattletimes.com/business/rei-now-limiting-retur...

Before that there was no time limit though. I remember becoming a member in 2011 when I moved to a city with a local REI and that was one of the main benefits they pitched. I don’t miss it because I never returned anything after a year (or even a few weeks).

REI started a trade-in program that serves a similar function and probably manages to foil most of the people who would have abused the system in the past. I think it goes well with their overall “earth friendly” ethos and brand identity as well.

So basically this is for people who bought and use noise cancelling headphones and want to put back noise in their life.

What about...removing said headphones and listening to the life around you? And even better, open the window?
Clicking through here led me down a medieval rabbit hole and I reading about medieval math education, it seems music was an integral part of mathematics at the time with arithmetic (numbers as abstract concepts), geometry (numbers in space), music (numbers in time) and astronomy (numbers in space and time).

These days using music or sound as an aid in mathematics is very uncommon. These days we only use graphs, diagrams, geometrical figures and. We have stopped using one of our senses for math. When did this happen?

I imagine sound could be useful for alternative ways of experiencing mathematical object as not just geometry, but also as ways to explore concepts in higher dimensions by using audio for some dimensions. In complex analysis, colors are used to visualize four dimensions but audio remains very niche.

A bunch of numbers in a table is often difficult to make sense of by looking at the numbers but can give many intuitive insights when visualized. I imagine there are probably things that are easier to make sense of if your hear it than visualize it. Maybe music should be put back in math education.
So the government will decide what you can buy because… why?

Big corporations want it? Big corporations want the biggest chunk of your money so they want you to have a “complete” freedom of your money so you can spend it on their products.

All these arguments sound to me like conspiracy theories because I don’t see real examples. Show me a scenario where the government would want you to not buy something. Like what would that be? Guns? Yeah I’m the EU they will block you but that’s because it’s illegal.

Do you feel like they will limit the amount of alcohol you can buy? That would be an example. But prohibition has been tried before. Ppl want alcohol and ppl vote.

Also why would the government care so much about what you buy? If their plan was to control you and stuff why do we have so many privacy laws and initiatives in the EU?

Also this seems like a very long term project. Do you believe the ppl working in the government are soooo competent?
At a glance the study doesn't seem to investigate that at all.

The authors are from Israel, so I guess the participants are Israelis too. That's one of the more ethnically diverse places, but only 12% of Israelis are of African origin. Of course not all of Africa is in the tropics, but there are a couple of Asian Israelis who are from the tropics, so let's estimate it at about 12% with mostly tropical ancestors. That might just vanish within the noise of the data unless you specifically look at the correlation to ethnicity.
Show HN: Thread-Parallel Decompression and Random Access to Gzip Files (Pragzip)
Hello HN,

I'm very excited to have finished a gzip decoder that can speed up decompression using threads. On my Ryzen 3900X, I measured a 8x speedup over standard gzip, reaching 1.6 GB/s for a synthetic file with a consistent compression ratio of 1.3.

A functional decompressor like this is kind of a first, that's why I am excited. Pragzip implements the two-staged decompression idea put forward with pugz, which unfortunately only works with gzipped text files not arbitrary files and has many more limitations. I think my main contribution over pugz might be a fast (~10 MB/s) data-agnostic deflate block finder, which might btw also be used to rescue corrupted gzip files). Note that pigz does compress files in parallel but it effectively is not able to decompress not even their own produced files in parallel.

You can try out pragzip via PyPI or by building the C++ pragzip tool from source:

python3 -m pip install --user pragzip
pragzip --version # 0.2.0

Here is a quick comparison with a very Huffman-intensive workload tested on a 12-core Ryzen 3900X:

base64 /dev/urandom | head -c $(( 4 * 1024 * 1024 * 1024 )) > 4GiB
gzip 4GiB # compresses to a 3.1 GiB large file called 4GiB.gz

time gzip -d -c 4GiB.gz | wc -c # real ~21.6 s (~200 MB/s)
time pigz -d -c 4GiB.gz | wc -c # real ~12.9 s (~332 MB/s)
time pragzip -P 0 -d -c 4GiB.gz | wc -c # real ~2.7 s (~1.6 GB/s decompression bandwidth)

I have unit tests for files produced with gzip, bgzip, igzip, pigz, Python's gzip, and python-pgzip. It should therefore work for any "normal" gzip file and is feature-complete but needs a lot of testing and polishing. Note that it is very memory-intensive depending on the archive's compression factor and of course the number of cores being used. This will be subject to further improvements.

Bug reports, feature requests, or anything else are very welcome!

It is probably impossible to provide such numbers. The best we can do is study the sources, which suggest bathing was a common occurrence.

Exactly as parent stated, there already are organisms evolving to consume plastic. The same is probable to happen for PFAS. It has carbon therefore it contains useful energy that some creature will eventually evolve to digest and outcompete other organisms.

That of course is to the detriment of the very properties we desire in these materials. Just as flooding the environment with antibiotics made them less effective, so will flooding the world with plastic will make plastic lose it's advantages. Just more slowly. This is another reason to not contaminate the environment with our externalities.

Hey, awesome work! What are the steps I need to take to build something similar, let's say to generate awk or sed processors/filters using plain english?
Absolutely.

Another answer I don't recommend is "PR welcome". Accepting some random person's feature then getting it merged comes with lots of costs, from the one time cost of code reviews to the ongoing cost of maintaining the feature.

Only say "PR welcome" if it is really welcome.
Look into Reckful if you have any interest in this subject
I noticed socks I bought from Uniqlo had an RFID tag in the label. Maybe that's for the same reason? They know which items haven't been sold.
As someone who makes lots of merge requests, please don’t add the further statement. In my experience while it’s well intentioned, it (understandably) frustrates contributors because it’s making an assumption that they aren’t valuing your time, which you don’t know.

Just my 2¢, at the end of the day do what feels best for you, but you may drive away some contributors.
Not sure how true it is, but my HS European history teacher blamed the Catholic Church and nobility for misinformation regarding the so-called Dark Ages. Apparently, they weren't too happy about widespread atheism or peasants burning the tax and accounting records.
> To emphasize even more, you do not need to explain yourself at all, in any way.

I would suggest that you should not explain yourself in any way. Chances are they would just view that as an open door to argue their point and they will try to use your words against you.

A polite no is still a no. Some people just need time to realize that.
Is this not also the case for the "I replaced my relative's computer with an iPad" stories that were popular a few years back?
And for some reason I thought it required triangulation, in that noise cancelation can't be done with sound in a space because the inverse of the sound you hear is relative compared to the person a foot or two away from you.
Doctors prescribed morphine to my Dad when he was close to his end, he was staying at home and not expected to leave again kinda thing. I had to drive around 3 cities hunting for a pharmacist that would fill the prescription; after getting a physical paper copy signed by the doctor because thats not a "phone it in" drug.

Drove all day on that one. They'd say "sure no problem" on the phone then "oh we can't do this" when I showed up. This was a decade ago, but nobody involved or that ive told this story to seemed to think it odd.

Certainly no one has ever suggested to me that a pharmacist refusing to distribute pain meds for someone who needed them was a political act that required society and the mechanisms of state to become involved. Is this just misconception on my part, or is it "some drugs must be available and others can be pharmacist's discretion?"
In EU the passport also contains your biometric identifiers. The RFID chip on the passport contains your fingerprints and picture. This also allows the electronic passport control at airports etc where the machine compares what you look like to the photo on the chip.
That's why I said "presumably". If it turns out that a group of people who've lived in the tropics for the last 50k years do not respond to UVB in the same way, then the hypothesis isn't refuted (and indeed it is validated).
I meant baths were not constructed the same way all over the world. You described a specific soft kind of wood and a particular construction method.
The study I cited was of mammals. We aren't going to learn anything useful from the lifestyle of cold-blooded reptiles. For one, their metabolic rate is much lower.

$1B is a lot of money…he has obviously determined it’s well worth it to spend a few million in legal fees to try. Even if they settle (which more than >90% of cases do) maybe he cuts that penalty in half…even if he knocks 10% of financially it’s well worth it. Even if he loses and ends up paying his legal fees and their legal fees its clear he has determined it’s well worth it.
No chance to convince my parents to do OMAD. But would like to try it myself.
How big are your meals if I may ask? Actually would like to start going to gym again and gain weight/muscle mass, so would be really interesting to hear if that could work with OMAD.
The best thing to do is to decide where your boundaries are, and then tell them.

I was in your position many times. I was so frustrated to feel like the other person was entitled to my time. Then I had to fight my urges to tell them to fuck off, wasting even more time and energy in the process. Even if I replied, it wasn't helpful to anybody if I was being polite but passive-aggressive.

Then I realized that it was a huge misunderstanding. How can people know what my limits are if I don't tell them? We don't all share the same sensibilities and background. Instead of getting upset, it's possible to tell people and move on. 99% of the time people understand and respect that.

Since then, I adopt the following classification:

1. Is the feature interesting to me? Let them know

2. If not, would I accept a PR for it? Let them know, with also some criteria for inclusion. No half-baked attempts please.

That's it.

One surprising thing I discovered is that I wasn't entirely clear where my limits were. Going through that process over and over again helped me figure that out. And become better at communicating clearly.
Don’t tell that to the lions.
It’s a bit silly that you’ve essentially written here “abandoning all nuance is bad, that’s what the other side does!”

This is ironic of course, since you’ve ignored the nuance that the Keira Bell case was specifically regarding the ability of children under the age of 16 to consent to this treatment themselves. It does not question the lawfulness of the treatment or guidance itself, and it has been clearly established that parents or guardians can give consent. I have absolute sympathy with Keira Bell and the struggles she has gone through, but it seems clear we should want to avoid using the legal system to intervene in clinical decision making to the greatest extent possible.

For the record though, I disagree with you - I don’t think it’s a particularly complex issue. It has certainly been ratcheted into a hot-button culture-war topic by quite a lot of ignorance and deliberate muddying of the waters though, which can have the effect of making things seem more complex than they really are. You’ve just done this yourself—even if unintentionally—in your comment.
100% agree about the DS degree. I have plans on getting a MS in stats starting in a year or 2. All the DS degrees list that you have to take a programming (Python/R) course and database course. I don't need those.

I want to know WHEN and WHY to use one stats method versus another.
I used to believe this, based on the mathematical proof referred to.
But every proof relies on assumptions, treated as axioms, ideally (but rarely) all noted.

This particular proof assumes that the clock is perfect, with no jitter or delay between one place it is used and another. There are more ways for a clock and uses of it to vary than you probably imagine possible.

It also assumes the A/D and D/A converters produce exactly correct results, which none do. We expect them to be close enough.

So in fact the output is as close to the same as the input as anybody cared to ensure, subject to cost, component tolerances, and amount of attention spared.

In practice, it is almost always as close to exact as anybody listening cares about (and better than a phono needle could manage). But there are ways for digital systems to produce bad results, by happenstance, laxness, or just normal aging.

Few ever check the calibration of their equipment.
I would offer them to join the project as a collaborator or just stop responding.

Put very simply: Edmunds, the experts on cars, give the ID.4 an 8.2, and the Ioniq 5 an 8.3. They're both great cars.

Here's a review comparing the two. https://insideevs.com/reviews/586981/hyundai-ioniq-5-vw-id4-...

The one place the ID.4 wins is performance. If you want a fun drive, it's better. But that's not high on my list. Any EV is going to be more fun to drive than my ten year old Honda Civic. But the rest, the Hyundai wins the day.

Edit: also you're presuming I'm American and have your country's tax breaks, etc. Not the case, thankfully.
Or it implies that people with debilitating conditions don't survive for very long because the Bushman lifestyle is much worse for them in a wide variety of ways, so don't get factored into assessments of the surviving population's general health.

More generally, the fact that a specific group of people who live outdoors and forage and hunt for food are generally in quite good physical shape is probably a better indicator that exercise is good for the physique (and lots of food and a sedentary lifestyle bad for it), than an indication we should go to the supermarket and buy more red meat in proportion to the amount they consume it. Older people can be wiry and surprisingly agile in vegetarian communities where there's [just] enough food and their traditional lifestyle entails walking around everywhere too, but that doesn't mean vegetarianism is a solution to first world dietary problems either. I'd be cautious about conflating agile with free from discomforting ailments too.
Alternative.

My parents weren’t cheap. But they were responsible with their money both had pensions and retired when they were 55 and 57 respectively.

They have gone on two cross country 4-6 month road trips. They are now 78 and 80 and are still mostly healthy. They only stopped traveling because of Covid. They are slowly getting out of their bubble.

They both said that they have had a long enjoyable life and will have lived a life without regrets.

While I won’t be retiring at 55, my wife and I are planning a 2-3* year adventure where we will be traveling across the US in a method that’s comfortable for us - flying everywhere and staying in mid tier extended hotels.

We are starting this near the end of the year. We just sold our newer car to save money and we are selling our old car before we leave. We are renting out our house.

Am I worried about a long life? No. I’m more concerned with an enjoyable life with no regrets.

Yes, I see my doctor(s) regularly. We chose hotels partially because they all have gyms and most will have pools for working out

Do I eat overly healthy? Mostly no. I enjoy food. But we mostly keep our weight under control.
Totally not trying to start a flame war here, but regarding keyboard shortcuts on Mac OS: I actually love the fact that there is the command key, and how it makes sense semantically. Cmd+C to copy works parallel to Ctrl+C in the terminal, which lets me rely on muscle memory for clipboard operations without conflicting with CLI ops!
Also, any shortcut involving the Cmd key will be a command that you issue, and anything with Alt will execute an alternative variant or something. I never noticed this until someone pointed me to this, but I’ve appreciated the consistency ever since.
Could you put some mL estimates on those two measures? It would seem to me that I'd need 50x as much oil to bathe in than I'd need to cook for a half a day, making me think I'm clearly thinking about either the bathing or the cooking quite a bit wrongly.
The most obvious adaptation since venturing from the tropics is reduced pigmentation to adapt to less intense UV radiation. Nose shapes are also influenced by climate.

The idea that we stopped evolving sometime before we spread over the globe is obviously false, with the number of adaptations that are plainly observable on the outside.
Okay, but can I get a schematic of how that's supposed to work? The opening on the pechka is on the side—what, you slide inside like in an MRI and then somehow chuck water onto yourself?

Pretty sure just filling a proper wooden tub with the hot water is a lot simpler.

For the context, back in my childhood I spent several summers in a house with a pechka (it's still there), and visited a couple others. Those could only fit a child at best, but the principle is the same: you shove the pots from the side into the tunnel above the fire.
Apart from speed of response that many comments mention, isn't there a more fundamental issue with active suppression using wave interference in a 3D space. There will be places where the superposition of the amplitudes of the original wave and the active/added wave will cancel each other out but there will be places where they will superpose additively. Hypothetically one could position the source of the active suppressing waveform where the suppression target originates, but that would not be practical. Of course, with smart and speedy enough tech one could arrange the waves to cancel at a specific point.
Aren't most studies contradictory ? For one study claiming A you can find another claiming the opposite.

In the 80s/90s there was this constant fear about cholesterol and eggs (perhaps promoted by the cereals lobby?) : did people's habits change? If yes, it was probably because of the monopoly of TV as the main source of "information". Nowadays with internet, every one follows his own little bubble of information.

Outlook seems to be pretty good; there's apparently very few deaths resulting from this outbreak. I think survivors are likely to have some cross immunity for smallpox.
I don't usually let it go in the kids room unless it's right after they've cleaned. The main problem areas in the apartment are right in front of the door, where they take off their shoes (so much sand, always!) and under the kitchen table. And from my messes: in the kitchen, from cooking. Those are the areas I was vacuuming most days by hand before. Again, the main problematic things for me are dragging around cables (from my stereo) and moving rugs, but those aren't more than a few seconds to put back. It gets stuck on something else maybe every 2-3 runs.
