The title is terrible, it should read ketosis/ketones may prevent, reverse age-related effects within the brain.

"Low carb" as the title currently reads does not necessarily result in ketosis and your body/brain running on ketones, which appears to be the scope of this study. There is more to dietary ketosis than low carb, just as an example carnivore or paleo diets are low carb, but those will generally not result in ketosis, in protein rich diets your body will convert the protein to glucose which will continue to be the primary fuel for the cells in the brain/body.

If you have never entered ketosis and experienced your brain running on ketones, I would suggest you experiment for yourself. I would say a minimum 2-3 months which should be enough time for your microbiome to change and your body/brain to adapt primarily running on ketones.

> Maybe I'm just weird, but for me that's one of the most satisfying things to do.

I'm with you, but also agree with the GP. It's super satisfying to get stuff like that cleaned up, but one of the most shocking things I've come across is callers who do absolutely bizarre things that rely on side effects from those methods. More than once, refactoring a big method like that has spiraled out of control fixing all of the callers as well.
Take some ketamine :) ... I'm stating this as someone with first hand experience, so it may seem hand wavy and "made up": memories are visual and those visuals directly trigger your nervous system which then responds and often impacts the visual memory replay (often cutting it off or moving to something else). Your nervous system is also constantly telling your visual system what to "lookup". Ketamine dissociates the nervous system from visual memory so you can sort of play the memory through like a spectator. I think this is why it is so effective at treating things like PTSD -- the memories are often so frightening or triggering to the nervous system that they cannot be replayed, understood and integrated... but with Ketamine cutting off the nervous system they can be understood without a panic attack or heart rate shooting through the roof.
Something always worth remembering: The brain is not even as well understood as we'd like to. For what it's worth, they might just be measuring something that's analogous to a data bus. E.g. in PC terms: I can probe the data bus' copper traces on a PCB, but that doesn't really tell me how the actual flash memory silicone works.

(This doesn't make the research pointless though).

Anyway, I was mostly inspired by an article on how to set up Steam in a container - it has all the details, including how to pipe Pulseaudio inside (so in my case, Youtube videos in Firefox can have sound). Except mine is debian-based (so debootstrap instead of pacstrap to populate the container).

The hoe I use for de-weeding my garden was my great grandfathers, and is probably 100 years old. It functions pretty much the same as it did when it was new. My father had to put one new screw in it I remember, so it has served its purpose continuously for 100 years with ~20 minutes of maintenance.

A similar small bit of software would need recompiling monthly, and rewriting every 10 years, at huge labor costs, just to keep the same functionality.
This does not mirror my experience at all, it is very rare not to be able to pay with card at all, even at shawarma/kebab/hotdog stands. The only places that are cash-only are drug dealers and some other places in Christiania and cheap hairdressers who opt in to not report their earnings to SKAT all that accurately.

Also, the Denmark-only Dankort is dying and its demise is happening fast: they are coupled as Dankort/Visa cards and the POS might decide to prefer Dankort but accepts Visa just as well. Neither Google Pay nor Fitbit Pay support Dankort and I have not seen transactions fail that would work with my Dankort.

Also, cash transactions are pretty rare too. Even older people use contactless, I have never seen cashiers have to pick coins from someone's hand as is customary with older people in Germany. Sometimes days pass without me seeing anyone pay with cash. In my experience the main source of cash transactions are German tourists.

Ah, this is not what I meant but just as relevant. I think you are essentially saying that you don't have to send as many bits per second that the signal frequency is capable of? I suppose that would satisfy any arguments that focus on bit throughput.

Noted that the underlying cause for the improvement comes from ketones. This should indicate that intermittent fasting would also show similar results. Low carb diet, keto diet, intermittent fasting, they're all just different ways to switch the fuel source from glucose to ketones.

The issue that people, at least Americans, run into is that consuming a “normal amount of carbs” is shockingly hard if you’re not consciously trying to avoid them. Foods that don’t really need sugar in them often have it in huge amounts because it delivers more flavor oomph (and separately delivers a dopamine hit). This is especially true in the aftermath of the war on fat because, shocker, fat tastes really good and when you remove it, food tastes worse. How do you make up for that? Add sugar.

Ah, therein lies the rub.
US GDP per capita is going up at the same time as education for the same reason the size of the v average dwelling has gone up; Richer people consume more. Education doesn’t make people more productive. More productive people buy more stuff.

If you give everyone a Bachelor’s degree they will not become 2x as productive. The people are different. The education is less important than the difference in the people. Education is not making them that much more productive. It’s certifying them as already being more productive.

The evidence for the economic effects of evidence is really weak. Richer countries spend more on education but the extra spending on education follows the getting rich, not the other way round. Ghana is a lot more educated now than 1950’s France, and a lot poorer. China’s massive economic growth from the 1980’s to the 2000s was based on a populace that mostly hadn’t finished primary school.

Regarding other first world countries the US is far, far richer than them[1] and has a better education system.

Not sure if I believe all the hype about these wild benefits low carb/keto diets have but I will say I've felt so much better on it...I rarely feel tired anymore and have been weirdly healthy the last 2 years. My doctor was surprised with my blood tests and weight loss when she heard what I eat lol. I'd never go back to the amount of carbs I was eating.
You have little control over businesses transmitting purchase data to Facebook or other data aggregators.

Best you can do is withhold information at time of purchase. Use cash, don't give your email, phone number, etc.

Some businesses are clever and dangle a carrot with the request for PII such as emailing you the receipt or texting you status updates. You will have to learn to be "that guy" and politely refuse, or give bogus information.

truth be told; I consider myself highly technical, even with things like FreeNAS.

I went to check my custom built FreeNAS one day, and it's off, and it wouldn't properly boot so I needed to haul a monitor out to see what was going on...

I finally hit the age where I don't care to deal with shit like that anymore, and finally pulled the trigger on a synology. Couldn't be happier.

It was fun setting it up and configuring FreeNAS the way I wanted, but overall bleh because I didn't get the right HW (went dual core atom at the time, not beefy enough for plex re-encoding).
Sure, but computer monitors are typically much more expensive than TVs of the same size.

Computer monitors are designed to be looked up close, which mean they are often at a higher resolution and higher quality. Furthermore, especially with gaming monitors, high refresh rates and low response times are important. A TV only needs 60Hz and response time is mostly irrelevant unless you are console gaming.

>Eating normal ammounts of carbs isn't going to kill you, it's literally our main energy source.

Its only the main energy source because its the main dietary intake. If you change your dietary intake consistent with dietary ketosis then carbs/glucose will not be the main energy source, ketones will become the main energy source.

Consider two things: 1) when in a fasted state, the body will begin to produce ketones and begins to run off of ketones instead of glucose (which our body can continue to make without eating carbs) suggesting ketones are the default energy source until we introduce dietary carbs that spike insulin; and 2) as the study notes ketones are the more efficient fuel source for the brain only because our modern diets carb laden and insulin spiking our brains are contantly using glucose instead of ketones.

Ask HN: How to communicate better with people whose first language isn't English
I've recently experienced several situations where upper management thought that they had clearly communicated their requirements for a task, but the person who completed the task didn't understand what was expected of them.

With that in mind, do you have any experiences or advice for improving clear communication with and between people who speak English as a second language? What policies and standards worked best, and what failed?

How do you encourage people to ask for clarification if they don't understand? Too often I've seen ESL people very reluctant to ask questions, whether it's in person, chat, or email.
His autobiography "On the Move" is deeply personal and humbling. The guy was a neurologist, bodybuilder, crazy motorcyclist, marathon swimmer and a top-notch human being all rolled into one.
It's a good move, but honestly they're moving in a direction that is less interesting to me.

Ten years ago, Sonos was the sine qua non of easy home audio, becuase they were ahead of the game on interface AND gave you a great way to access your music library anywhere in your house. The extra bonus feature was their usage of a proprietary mesh network, so the music didn't stream over your increasingly-overburdened regular wifi network.

Well, most of those advantages have kinda gone away. Moving in reverse:

- wifi is way better now; I never have dropouts anymore.

- The Sonos interface is now way, way, way behind the Apple music interface IMO. My nontechnical wife never warmed to Sonos at all, but she can use iTunes on her phone with aplomb, and playing music in the living room uses the same interface as playing music on her headphones.

- Library access was a sticking point, given that Apple formerly relied on a convoluted approach here, but by subscribing to Apple Music the problem is completely sidestepped. I pay for this mostly so I don't ever have to plug my phone into the media box and sync files -- for me or for my wife. That's worth the price right there, to be honest, but in addition to that you get access to nearly anything. It's rare I can't find what I want there. (We DO still buy CDs locally, but only because we live in a place with a real indie record store.)

The tl;dr is that we were already kind of Done with Sonos when this whole kerfluffle started -- we have sunk costs here, but as these devices stop functioning we'll move to something else that plugs into the Apple infrastructure better. Even if we have to revert to local music only due to some Apple failure, there are still better/easier options than Sonos at this point.
It’s very sweet of you to say so. But alas I’m as difficult as the rest of them.
Here is a radical idea: what if everyone paid their tickets through a public infrastructure tax. That way neither the person with cards or cash in their wallets has to worry about getting home. We don't even need to carry a wallet that could get lost in the first place!
Each test kit has a limited number of uses[. The first batch of thousands of test kits had a flaw and couldn't be used[1]. With a limited number of kits, they had to limit testing to high-risk people.

As I've written on HN before, a great deal of the problem is that the current administration appoints political donors and anti-government activists to important roles in agencies handling science and medicine. These are mid-level people whose names almost never end up in news.

So you have incompetent decision makers appointed throughout the organization, funding cuts, discouragement of civil service at all (through things like killing debt forgiveness and stagnating wages), and an administration that publicly denies the problem is even serious because it's afraid of the stock market tanking.

Add to that that the State Dept has been gutted and has many hundreds of open positions that the administration refuses to fill, and you have more disasters like allowing likely-infected Americans to return to the US without testing or quarantine.

Would a time restricted feeding type of intermittent fasting, with a 16/8 schedule, really result in the production of ketones? I thought that it would take about a day and a half or longer to exhaust carbs and start the switch to ketones. Then it’s only the longer fasts (like 5/2 days) that could help.

Try to provide a package of a GUI app "for linux". After you support centos, fedora, debian, ubuntu, gentoo and arch, you'll maintain a mess of brittle packaging scripts for years, breaking at each release and some updates. Just making the first release for each is a challenge. Even app images, the least well integrated system will fail at some point.

You'll see how stable is diversity.

Then package for windows xp. It probably works on windows vista, 7, 8 and 10.

Now I do see a lot of value in diversity. Resiliance, ethics, competition, collaboration...

Stability isn't one.

While there are reasons for concern, I don't really blame Philips (Signify) for this. They released the v1 hub quite early in the smart home space. It wasn't compatible with Apple Homekit features when they were released due to hardware limitations for reasons they presumably couldn't have predicted (unless they made it a more capable and expensive device in the hopes it would support unknown requirements). They made all v1 owners an offer to get a new hub "free" with a colour changing bulb, though it's not good value if you don't want the colour changing bulb or find it on sale and don't care about the hub. The old hub will continue to work, just not remotely. After eight years, I think it's a responsible and fair response within the parameters of consumer gear. The only way it could be better would be if the hub weren't required at all, or it was more easily interoperable with other controllers, but from the start that would have meant a more complicated experience.

I was an early adopter of Hue, even though it's kind of expensive I enjoy the capability to change the colour and mood of room lighting. $400 worth of lighting hardware for a house over 15 years is less than the comparable effect of painting a single room. From the start it has good support for local-only implementations with good open source libraries.
You are thinking of a grey card: https://en.wikipedia.org/wiki/Gray_card

However color matching is more complex than that. "Color of the light source" varies considerably, not only due to the illuminant itself, but also the materials the illuminant is reflecting off of (e.g. walls). And color temperature only defines black bodies, which most light sources are not: you need information about the full spectrum of the illuminant to determine how it interacts with the material to be color-matched. This is getting a bit into metamerism: https://en.wikipedia.org/wiki/Metamerism_(color) (Of course, paint cannot match an arbitrary spectrum. Matching under specific lighting conditions is the least you can hope for.)

And the above is considering color of a surface only as a scalar value, but it's really a function of illumination angle as well, due to gloss. Direct lighting on a glossy surface reflects more of the color of the gloss, whereas oblique lighting reflects than the paint itself. Diffuse lighting is some combination thereof.

(I am not a color scientist by any means, just interested in the topic. Experts please correct!)
The v1 / v2 split was arguably Apple's fault. v1 launched before Homekit; then Homekit required special hardware authentication; then v2 launched to support this; then Apple walked back on the special hardware and allowed things to be done in software, but Philips had already made breaking changes for v2.

Again, Philips made the wrong call here.

> Is “means-tested” supposed to be a degrading adjective?

Yes. People who are on means-tested social safety nets are subject to these test which often make you feel degraded. They often make people fear they will lose their benefit. And in many cases they encourage people not to improve their lives (e.g. I better not take that part-time job, because then I will lose unemployment benefits.) It also creates an incentive to falsify information so that you can continue to receive said benefit.

UBI solves all that because it isn't means-tested, you just get it no matter what (Oh you improved your situation? You got a job, got healthy, etc. That's great! You will continue to get UBI.)
