Hmm another sleep article.

I'll share what I do. After being in the Army for a while, and waking up at 430 and going to bed at close to midnight for a long time during the week (there's no real "sleep schedule" overseas though) I've been working on tuning my sleep cycle for the seasons to great success. Over the last year I've been slightly altering my alarm each night based on when sunrise is (plus going to bed earlier/later as the days lengthen/shorten), and it's significantly improved how quickly I fall asleep, how easily I get out of bed in the morning, and how rested I feel. I'm not a huge "fitness tracker" guy (still analog in that regard, with a notebook for workouts instead of some app or a spreadsheet). No idea if there's any science behind any of what I'm doing and frankly I don't care. It works great for me.
It doesn't renew the questions. The questions started before there was ever a crash and continued without stopping!
It charges fast enough that you can wear it almost 24/7 if you plan ahead and charge for a bit in the morning and at night

There are real signs of a moral change in this upcoming generation. I suspect a lot of people are going to be very surprised when that wave comes in and breaks.
Yeah I think any random baby is more interesting than a comic book collection but maybe that’s just me.
i am surprised that the physical aspect of digesting the processed vs unprocessed food doesn't seem to really matter for that study. i'd have naively thought that chewing and swallowing a chick pea would result in lower nutrient uptake than eating an equal amount of besan. instead it seems a calorie is a calorie and the weight difference is entirely due to less consumption.
even if nutrient uptake is the same, i think it's clear the stomach and intestines are designed for dealing with unprocessed foods.
What you are suggesting is not possible for the government to solve IMO. You are basically saying that the school system needs to take on the role of parenting ("helping kids engage") in addition to actual education.

When the kids' parents have not completed school themselves, can't help or motivate their kids with schoolwork, etc... you need an army of mentors to help engage those kids. Unfortunately, disadvantaged kids outnumber such mentors by a large factor and such a system would quickly swallow any budget fed to it.
Not enough slave labor available like in other countries.

It's still totally possible to achieve this (at least in the US, and likely the world), but as a society we've decided it's more important that the top x% get a larger share of the pie than they did in those "couple of decades".
It's largely illegal to build units that are sufficiently small to be affordable. Zoning requirements in most places have square foot minimums and amenity requirements (such as parking).

That said, even "luxury apartments" give the wealthy a place to live rather than bidding on existing housing stock, and so do relieve price pressure on older buildings.
Re/ oura rings... anyone else paranoid of a private company having access to intensely personal data?

If I were an insurance company I'd be lobbying the shit out of these guys to see how much they'd charge me to get my hands on it.

Probably better for the environment that this failed. Construction would release so much CO2 that the California HSR would have to be as busy as the entire Northeast corridor to break even in terms of carbon impact. https://www.citylab.com/transportation/2011/11/how-green-hig.... That is basically a fantasy given that the northeast corridor passes through the densest megalopolis in the country, and connects seven major population/business centers, while the California HSR would pass through nothing.
There's a couple the things the author missed - not that it changes the conclusion that much, but adds more context.

The first is how the rise in indoor rock gyms in turn gave rise to youth leagues and competition. This has created a huge leap forward in the skills of elite climbers because many today (the "gym rat" generation) have been climbing only slightly less longer than they've been walking.

The second is how the funding of outdoor adventure/exploration has evolved through the last couple of centuries, from securing precious resources (though mountaineering never had much of that), to a sort of angel/philanthropic model (geographic societies and alpine clubs), to government backed nationalism, to the current gear branding and sponsorship that is fueled by social media. This current model drives a huge amount of activity in outdoor endeavors that have helped create the crowd sourced effect he's talking about.

Perhaps that's the problem.
USA has no (local) competition for internet, it’s almost all regional monopolies or duopolies where one (cable TV company) is expensive and ok and the other (copper wire phone company) is slow and unreliable.
While no individual person may deliberately do this, the gestalt does a motte & bailey with this, where "calories in = calories out" means that people are wrong to think about how different calories affect the body differently and interact with all the feedback loops in the body and dieting is just a matter of applying willpower harder and eating less, until you challenge it, at which point it's suddenly just a tautological thermodynamic truth that apparently is being thrown into the discussion for basically no reason and with no particular purpose in mind.

It really needs to just be retired. At its best its an unhelpful tautological statement, at its worst, inflammatory and thought-terminating. Not much reason to keep dragging it in to every diet discussion.
We know how the scenario plays out because we've seen the effects of automation playing out for the last 20 years. These fantasy jobs that people have been talking about since NAFTA never materialized. For working people home, health and general insecurity have skyrocketed along with household debt as wages have stagnated and fallen. We can either deal with reality as it exists or keep spinning ideological fantasies until the situation reaches a breaking point.
If they are truly strapped for cash because their house burned down but they don't have insurance they can still try to do without expensive vacations and other non obligatory expenses. If you can afford to keep paying $60k a year for 30 years for something that does no longer exist then there is no short term risk that is meaningfully destructive to your life.
Did you really need a $300 device to tell you that a night of drinking will undermine your sleep?

Except that NIMBYISM is everywhere. Trlling people to “just move” is not only unfair (see Katrina aftermath) it’s not reasonable since you are exerting undue influence over your neighborhood and essentially the right of others to live near you, but not on you.

I'm aware of pellet burning stoves. There are also smoke recyclers and burners for home stoves which make them even more efficient.

But in what way are those carbon neutral? (which is what I thought was the point of this entire thing)

And that doesn't answer my questions.
"Why We Sleep" by Matthew Walker is an excellent book for those interested in what science has to say about sleep (disclaimer: it's excessively good for you)
As long as the voltage is the same, you can buy or make (3d printed plus a little bit of wiring—you can find files on thingiverse) adapters.

The 20V line of DeWalt, Porter Cable and Craftsman are all compatible with slight modifications to the plastic on the battery housing.

I know that's too much effort for most people, but it's nice to know that it's possible.
I wouldn't be surprised if it's not a subscription model, and they monitize like any cloud service. As a user you just pay for the games, and the publisher has to figure out how to pay for the bandwidth.
Aren’t they already biased against older workers, though? Older workers and startups don’t fit together well.
Exactly my thought. This isn't about needs, it's about economic rights. If I can afford two homes and choose to buy them, I'm within my rights to do so. Attempting to limit the rights of people isn't going to go very well.

You'll also be fined for failing to deliver on the contract if you take time off due to sickness. You'll be sent home without pay when conditions find the mail room short on mail, but you are required to be available for work the rest of the day, just in case the delivery was late.

You'll be repeatedly told how much more convenient this is for you.
Because of everything you've outlined in your last paragraph and more, I don't know many competent C++ programmers who would call std::string or std::map "zero cost abstractions" with a straight face. That term is more commonly applied to things like CRTP, template policy classes and other abstractions that you pay for in compile time (and, depending on linker optimizations, code bloat), but not in runtime [1]. As you point out, an abstraction that does a bunch of extra work is by definition not zero cost.

[1] Yes, code bloat can lead to runtime performance issues as well. Common sense coupled with linker optimizations can usually, but not always, mitigate those issues.
I think it's more a case of the same inspiration (Hermes, the Greek messenger of the gods) than irony.

> > Safety is a function of the inhabitants of an environment's ability to mitigate threats.

> The evidence shows that isn't working.

No, the evidence actually shows that that does work - gun free zones are home to something like 99% of all mass shootings, and school shootings with a prepared police officer or teacher carrying a weapon tend not to make the news because they don't hit the level of 'mass shooting' in the first place.

And then there's the debate about whether forcing terrorists to choose a methodology other than guns is even a good idea in the first place - I'd rather have ten mass shootings killing ~4-6 people each than a single repeat of Oklahoma City.
As someone who voted for the the $10B bond, and would love to see HSR, all I have to say is: Good.

We have to admit that CalHSR is a failure, and building a train between Bakersfield and Merced is stupid.

The United States has some systematic problems when it comes to infrastructure. We see it at both the micro and macro level.

At the micro level, it takes four guys more than a month to fix an escalator at a BART station. Months to paint lanes on a street in San Jose.

At the macro level, $13B becomes $98B.

CityLab ran a story about why NYC stopped building subways.[0] In it, it plotted the cost subway construction cost per mile at different times in constant 2017 dollars. First line cost $125M/mile in 1904. In 1944 it went up to <$500M, and even in 1988, it was just above $500M. Not bad for 44 years. Then cost go exponential in 2017 and 2019, ending at $4000M/mile! This is stupid.

Another article (which I have sadly lost) compared the cost of construction in the US to France. I think they compared a Boston subway line to a Parisian one. The Boston one costs twice as much, and requires twice as many people for “safety”. I’m sorry, but this is grift.

Then of course there’s all the environmental and neighborhood reviews that cost more, and stymie everything.

If we want to make any progress, I’m thinking we’re going to just have to bust all of this up. Cut the red tape, and go with closed price bids. Hell, use foreign contractors. The French are apparently half the cost, faster, and high quality. Just hire them and be done with it.

3000/m on 500/y is extremely inexpensive. They will not find cheaper for 4 people without driving up transportation costs and killing leisure time. They probably have an affordable car, as compacts tend not to be "luxury" cars with many bells and whistles to maintain. Tuition, well, you pay for what's important to you, and obviously they would rather dump this into the kids than saving. Hardly worth criticizing as excess. Groceries and eating out are not going to get cheaper. They are already less than $10 per day per person. Again, one couldn't call that excessive.
The filesystem track at LSF/MM tends to focus on topics which impact more of the kernel than one specific filesystem, and we didn't have any of those topics for Btrfs this year. Plus, only a couple of the Btrfs developers were at LSF/MM this year, and we typically sync up via other means.
Would it be more accurate to say SubstrateVM? Or is it now called GraalVM Native Image?

Anyway this is sad as it brings back lots of memory. In the old days it was only Excelsior and GCJ that were capable of doing AOT Java. It was when Computer were slow, memory were scarce, and JVM is no where near good enough for Desktop Apps. ( Although I think that is still the case today )

Anyway I wish them Good luck.

Edit: I wonder why they didn't open source it?
Yes, I'm suggesting my proposal would solve the problem in your neighborhood. If you reduce the demand for something, the price falls. My suggestion clearly reduces demand for something, thus due to the laws of economics, prices will drop.
Very good advice. I think people used to get together more because it was necessary in order to communicate. Now, we can communicate pretty effectively without actually meeting anyone. But we still need to be social and interact. These days, we have to be more proactive about that whereas before it happened more naturally.
But the CA project wasn't canceled due to land owners protesting its development... so no the issues aren't similar.

Public schools are no good in SV, so either I have to spend $4500 as rent in a good school district or spend low in rent and send kids to private school. And $3000 is the cheapest you can get in a decent location in SV
> so why would I think this paper used the UN definition?

Because if you read the paper from the OP link, the authors cite that their definition of ultra-processed food is from Monteiro et al 2008 viz. the same UN definition the OP refers to which is widely agreed upon.
If you look at school districts that have more than one school: the schools in poor neighborhoods have worse results than the ones in middle class neighborhood. This is within the same school district so school funding is the same.

It is fair to say I don't know the parents don't care. However whatever the difference is, it is at home not the school.
My comment was mostly in the vein of wondering what a "cheap" (relatively) not-really HSR could have looked like and the answer is probably "not fast enough to get from Emeryville to LA in a timeframe where people would really use it."

And, of course, the rolling stock had various problems so I'm not sure what the theoretical top speed ended up being.
The general feel I get from most of my engineer friends is that Facebook's product is definitely not inspiring and doesn't "make the world a better place" (whatever that means).

But the consensus is that given the right amount of money, they would all accept an offer from them. And Facebook is known to pay very well.
Wow that is crazy, I don't usually meet people who like higher taxes.

One big reason to densify the suburbs (speaking of the bay area in particular) is that they're in Silicon Valley and that's where most of the tech jobs are (e.g., Apple, Google, Facebook, etc.). These cities are willing to let companies come in and collect that sweet tax revenue but are not willing to allow sufficient housing to be built to house all of those workers.
Another view on the Oura thing: https://www.medpagetoday.com/practicemanagement/informationt...

It's rather skeptical. Choice quote:

[...] The SRI researchers studied 41 healthy adolescents and young adults (average age 17). Sleep data were recorded using the Oura ring and standard PSG on a single laboratory overnight. Metrics were compared using Bland-Altman plots and epoch-by-epoch analysis.

The ring accurately detected "light" and "deep" sleep in 65% and 51% of the sleep epochs, respectively. It also accurately detected 61% of REM sleep epochs, with an overall overestimation of PSG REM sleep (by about 17 min). When the ring misclassified PSG REM sleep, the algorithm usually classified the epoch as "light sleep" (76%).

These data suggest that the Oura Ring is virtually useless in telling you if you are in REM sleep versus deep or light sleep. [...]

Latency isn't an issue with games that have high time to kill or are purely exploration based, which seems to be something Stadia developers have noticed in the examples.

There will have to be local rendering for nearby objects and particles, but this is feasible.

Upzoning increases the value of the land, but decreases the value of pre-existing built square footage, since it's no longer an exclusivist area. If you have a brand new mansion built to the highest standards on the premise that it will be located in a tranquil neighborhood you might be on the net losing side if an apartment building is approved next door.

In any case, you need to tear down your existing home in order to realize any gains, which few people are willing to do.
It's nice to get very quick, in-depth answers by experts.

But the forced login - why should one freely contribute knowledge if it is siloed by a company? - ads, frequent clickbait/opinion/irrelevant/crazy/advertisement-style answers and irrelevant notifications ruin the experience for me.
Yes it boils down to this. People don't count things that increase your networth as savings (or in other words: nothing counts as savings). Therefore everyone's savings is somewhere around $0.
First of all, plumbers make good money. Second, expensive new developments that are unaffordable won't work. Ever seen the prices on them? Here in Los Angeles which isnt nearly as expensive, its about $3000+ but usually even more for new developments because they are high end. Please do some basic research beforehand.
I love SQL, but I strongly agree with this. It would be great to have a platform-specific low-level API for performance-critical queries. (Much like “unsafe” code in a managed programming language.)
It's interesting that the "ultra-processed" food example they give here is quesadillas, refried beans and diet lemonade. Not exactly the typical example of pre-packaged cookies and chips.

Another interesting thing is they're saying that stir-fried beef and veggies over basmati rice was not as processed. Both examples include meat, veggies and carbs (rice vs bread), is the simple addition of cheese enough to make quesadillas "ultra-processed"? The form factor? I certainly would never have come to that conclusion on my own. Is there a guide for this?

We need some better definitions here, maybe it's a little too cynical of me, but I'm wondering if all this study discovered is which foods tasted better.
Could ND or MT allocate 30-100bn in state funds for this? The federal grant was a huge loss but a drop in the bucket for how much this project has derailed due to the use of private contractors instead of public engineering.
(disclosure: i know Haskell but not Rust, and haven't actually implemented anything like this in a compiler. please let me know if i'm wrong!)

best guesses:

- dynamic dispatch usually involves carrying around¹ some function pointers (to your type's implementations of the trait methods). this means that when calling `x.foo()` on a trait object `x` of some trait `Foo`, the actual function/method being called isn't known until runtime, so the compiler can't optimize the call through things like inlining (which require knowing what's being called). also AFAIK jumping to some unknown function pointer is relatively slow on the CPU level

- since the compiler doesn't know the actual type (and hence layout) of your object, it has to be passed via reference, so there's some indirection overhead and it's probably impossible to e.g. optimize away intermediate values or be smart about the way they're kept in registers.

the problem is that the nature of trait objects (i.e. "i know nothing about this value except that it implements the `Foo` trait) kind of seems to require these things :(

Tons of federal funding is part of the reason the electrification of Caltrain is happening.

If newsom had taken funding for the statewide hsr and reappropriatied it to the regional Caltrain I imagine people would have been up in arms...
Is that what it is?

Every time I see some rant or new study on "processed" foods I really ask what it means for food to be "processed". There's a huge difference between a cooked slab of meat and a meal in a frozen box, but both are "processed".

I'm not really sure why quesadillas or muffins are "ultra processed".... what gives them an "ultra processed" nature? If you took a pile of steak chunks and a pile of cheese that would be way better than combining it with a tortilla? I have to doubt that.

If what you're saying is true the examples are very misleading; it really applies more to artificial flavors and things that change the texture of food and so on than it applies to specific food types.
