The bioglass toothpastes (i.e. the ones that contain NOVAMIN or Biomin) are doing something different than high-flouride toothpastes.

The biolgass ones aren't really "restoring enamel" but they "refill" (remineralise) the enamel with all the minerals that slowly leach out before the enamel actually wears away.

The flouride toothpastes act by hardening the structures those other minerals make up which increases the resistance of your teeth.

They both do different things but they work well together. In the US you won't find them both in the same toothpaste (only Biomin C/without flouride is FDA approved) but outside the US you can find Sensodyne with NOVAMIN and flouride as well as Biomin F (with flouride).

So depending where you live, you might want to give them another shot but making sure you use both bioglass and flouride (I personally do a dot on my toothbrush of both Dr. Collins Biomin Restore and Colgate PreviDent 1.1% NaF 5% KNO3). At least for me it has worked a lot better than just doing one or the other.
Show HN: mystery-o-matic – A daily random murder mystery
One of the best tech articles in 2009. Short and to the point.
And some get free entry to Harvard because they got admitted and have full need-based scholarships.
That’s interesting, thank you. Some interesting projects. But for my question (I should have clarified in it) I was thinking about their infrastructure stack as well.

In general I’m just curious about where the scaling bottleneck is right now.
> This can lead to absurd outcomes. The UK had a very hot day last year, with the Met Office reported a "record breaking" temperature. The problem is that this temperature was recorded by a thermometer right next to a military airbase runway at the exact moment three fighter aircraft were landing. The temperature spiked up to the record level for 60 seconds and then dropped again, with the spike+drop being quite massive. Finding this out took a year of FOIA requests, done by independent bloggers of course, not journalists.

I'm going to need a source on this. This doesn't even really make sense to me, because a single 1s spike (in either direction) should be filtered out. It also doesn't make sense how this would significantly affect a model which is performing a multi-decade analysis unless that single 1s spike was used to represent at least a month's worth of temperature. Which as far as I know the data is being pulled at at least a daily rate if not more, so the spike would disappear.

For the "no warming" part, let's adjust things a little bit to be more clear. First, let's clear that noise. It is all jiggly and difficult to read and trend going on. Let's select the month of June (middle of the year) and then select a 12-month time scale. Interesting, the beginning and end have the same point. Let's now find out if this is a coincidence or not (current window should be 2006-2022). If we move our window to 2010-2022 we see a clear trend line up over the last decade, but it is noisy (-1.07 -> +0.96). So let's go in the other direction. 2000-2022 seems down, slightly. Let's keep going. 1990-2022, okay, very clear upwards. 1980-2022, very upwards. 1970-2022, we're now at -1.65 -> +0.96. 60's, seems we've stabilized. 50's, oh, difference is decreasing again. And we keep going and see a clear trend of increasing.

I think when we're talking about a multi-decade effect we need to look at... multiple decades and be a bit more careful to not only look at one single window. Especially with numbers jumping around a lot.
I get that as well and I live somewhere, where HFCS is not used, so I don't think that is the culprit.

Personally if given the choice between a regular coke and coke zero, I will choose the zero every time.
> PRC has significantly more navigable rivers kms and better port capacity than US

Rivers in mountains and low quality soil, not connected to any productive land. Look up any map on agriculture land and you'll see their soil quality. It's bad. Compare that with the USA and Argentina. We have both the best in the world.

Then look up how much fertilizer is used in their agriculture, per hectares of arable land. It's bad.

https://data.worldbank.org/indicator/AG.CON.FERT.ZS

There's more advanced graphs here to see the relationship between fertilizer and crop yields:

https://ourworldindata.org/crop-yields

All your numbers may be okay. But the main Zeihan argument is two fold: first, the same from the book "Why Nations Fail". China is not great in their political institutions. It's bad. For example a HN from YESTERDAY:

https://news.ycombinator.com/item?id=36554818

The second Zeihan argument is demographics. After the One Child Policy, China is the country where population is getting older faster in history, and faster than any other country today. It's bad.

Look up the data:

https://ourworldindata.org/grapher/median-age

There's a direct relationship between median age and inflation. Because older people consume more than produce, lowers productivity, and that increases prices. From the IMF:

https://www.imf.org/external/pubs/ft/fandd/2016/03/juselius....

You may keep inflation down when population ages. But that just destroys growth, for example Japan. And China economy depends on growth.

The Biggest Scandal in Speed Typing History [video]
That’s (IMO) the right way to do it, but it’s also a harder pill to swallow from the C standards side: functions that die as a side effect rather than being UB are less precedented, have to be taught differently, etc.

C’s lack of iterators also means that indexing bugs are more likely in idiomatic C programs than they are in equivalent C++ or D programs. This is another place where the standards body should improve things, but it also means that they’re somewhat constrained when it comes to slice proposals: making every index be potentially fatal is less palatable when your programming language doesn’t divert people away from indexing as much as it could.
My personal observation with sugary food (maybe applies to aspartame as well): I eat a healthy meal and feel full. If I then eat some dessert, I want more and feel less full. As if my brain says: Look, you found a rare source of sugar. Sugar is good for me. Eat more while you can.

> How do you enforce rules without hierarchy?

This is why I'm more of a pragmatic minarchist.

People will continue to keep forming groups and multiplying their efforts and that creates power imbalances, and people will continue to keep seeking to try to wield that power.

So what needs to happen is that the government, corporations, unions, and organized religion need to be set against each other and kept in balance. That only happens through the people being educated though and being involved and able to restrict what they can do. Although corporations themselves are formed like dictatorships and that needs to fundamentally change so that they're at least more like representative democracy.

There's still going to be power hierarchies, though, but the point is to minimize them.

Of all the different philosophies, though, anarchism is at least solidly in the right direction, even if the end goals are impossible. But I think its a lot like the "paradox" of intolerance, where the naively perfect world isn't a stable optimum, but that doesn't invalidate getting closer to that being better.

AMD GPU drivers come with Linux distributions by default. There's literally nothing you have to do, unless your GPU is very recent.
Changing the fingers absolutely changes the readings on a pulse oximeter. They also take at least 30 seconds to settle down. (At least mine do.) I use 3 at a time in the mornings when I check my vitals and when they read within 1% (e.g., 97%, 98%, 98%) I record the lowest reading.

„These estimates are derived from the number of directory requests counted on directory authorities and mirrors.“

Depending on how these numbers are obtained, there is a non-zero chance at least part of this increase is caused by us.. note that this number is not indicative of the amount of users or origins (i.e. physical source addresses), but only count directory requests.
> Also, I've never tested this, but I believe mapped files will get flushed as long as the system stays running. So if you only need resilience against abnormal termination rather than system crashes, it seems like a good option?

Linux will not lose data written to a MAP_SHARED mapping when the process crashes.

But! Linux will synchronously update mtime when starting to write to a currently write protected mapping (e.g. one which was just written out). This means (a) POSIX is violated (IMO) and (b) what should be a minor fault to enable writes turns into an actual metadata write, which can cause actual synchronous IO.

I have an ancient patch set to fix this, but I never got it all the way into upstream Linux.

What you can do is mmap a file on a tmpfs as long as you trust yourself to have some other reliable process handle the data even if your application terminates abnormally. This is awkward with a container solution if you need to survive termination of the entire container.
Probably start with wlroots if you want to target multiple Wayland desktops. There are multiple compositor implementations now, so grabbing a framebuffer isn't quite as easy as it was in the 90s.

You should check out Flameshot and Spectacle if you want feature-complete screenshot apps on Wayland. If those don't suit your needs, then you should consider a custom solution.
> Also dealing with AMD GPU drivers is just as difficult.

This was true ten years ago, and remains true only for hardware dating back to that time period. My old HD7850 is a royal pain to get running properly on a modern distro.

For any remotely recent GPU that's supported by what's built into the linux kernel, it's pretty much seamless. There are no specific driver updates to deal with, which model of card does not matter, etc. It's all just built into the kernel.
I'm an engineer, not a scientist, but I've worked a lot with them, and also worked for many years directly with artists. I think we can work together much more constructively than we do. but in each of those three areas, we really do approach work in a very different way. in the end, I think the differences are a net positive, but they certainly have to be managed.

Frankly it's bullshit. The Putinist narrative that democracy is a sham makes sense for a man isolated from the real world that doesn't use the internet, but it's stunning to me how disconnected some people in the west can be from the society they live in.

I have family in the British military at a moderately high level. A friend was a researcher for an MP, and another a government adviser. Sure politics is messy, it's the art of the possible and expedient. Of course it's not ideal, but as the saying goes Democracy is the worst system of government except for all the others. You're never going to get perfect, the best you can get is consensus and the consent of the governed. We have that.

I revile Trump, but he did do one thing for us. He proved that US democracy is real. All the Washington consensus clubbyness was pushed aside, corporate capture and bought influence were bulldozed over. None of the establishment wanted him, but he's what we got through a massive grass roots movement. He was an utter disaster, but it was a genuine demonstration of democracy in action.
I'm one of them, as I'm a prolific open source contributor and maintainer. To argue that some high-profile authors don't get any monetary value from their public work is to be simply naive and uninformed. The two I mentioned have made careers on that work and derive the majority of their income from it.
You're missing the point, which is that kids who "chose" the right parents get vastly more opportunities than those with less luck at birth, and the lucky ones don't have to work as hard or have as much talent as the unlucky.
Despite the major ground that AMD has gained in the CPU space in the past few years, I think it's still somewhat seen as the less mainstream of the two x86 CPUs, and I suspect that a userbase who has opted into an alternative OS is more likely to seek out alternative hardware as well, at least as far as is practical. Gamers in general have more freedom of choice in hardware compared to other segments of Linux users (fewer specific technical needs), so perhaps that's what's being expressed here.
its probably enough time for the frequenter users to have adjusted their behaviors
An externality is a value (or a cost) which accrues to an entity other than the buyer of a good or service.

"Not freezing to death" is not an externality, it is consumer surplus, that is, surplus value from a transaction which accrues to the consumer in the transaction.

Yep that'll happen depending where you live.

Sensodyne has a bioglass (sometimes called hydroxyapatite, NOVAMIN, or Biomin) which is what you are describing however it's excluded from the Sensodyne sold in the US. The reason why is a long story [1] but if you want "good" Sensodyne you have to import it from literally anywhere else or buy a no-flouride biomin version (made by Dr. Collins who decided to go through the FDA process) in the US. Both are luckily pretty easy to get on Amazon however there's a bit of a markup.

True, but the self-driving cars argument has always been that if all cars on the road are replaced by self-driving cars, you will have no road deaths.

Which pretty much means that in this future, you will have no choice but to use a self-driving car. Which gives disproportionate power to automobile/SDC companies.

If the only motorized way to move from point A to B was Amtrak, I would be worried about the power Amtrak has over my physical movement too.
Ah, just mix 'em on the brush? Good idea. I will try that.

Yes, but it receives the input from an actual experience of the body it's embodied in - from an actual wet thing. As opposed to being served a simulation of the same.

And we've always had a shitty answer to dealing with the fallout.

Unskilled people are running out of things they can do or retrain to. Sending everyone to college has only destroyed the meaning of a college degree and created a surplus of postgrads who can't earn anywhere near their potential for lack of demand.

If we keep overfishing this lake, at some point (I am guessing in the near future) we will hit an inflection point where the number of people vastly outnumbered the availability of jobs, and social services will be strained to the point of collapse.

That is when the torches and pitchforks will come out, and these folks had better hope to whatever God they think exists that AI will save them. Because my bet is it won't.

As far as I know, this is not part of wayland core, namely you would need an specific and out of core wayland interface AND a wayland compositor which supports such interface.

Go to the wayland authority repo for interfaces, see if there is such interface (there could be many in dev), then find a wayland compositor which supports such interface(s) (or code such compositor). Then write your app code to query if a wayland compositor supports such interface:

- if not, gracefully fail.

- if it does, screenshot your surfaces.

That said, it is more an internal feature of a wayland compositor itself. So it seems more appropriate that a wayland compositor supports or not such feature, and if so, optionaly allows an application to remote control of feature via a specific out-of-core wayland interface.

I would feel better if it stays into the wayland compositior without the possibility for an external apps to snapshot everything.

That said, you could fiddle with platform specific stuff to shorcut the wayland compositor (on linux, drm mode settings and framebuffers).

Environmentalists do this all the time.

My town has a large popular off highway vehicle park open for at least 50 years.
It's probably less than 0.1% of the surrounding area that basically gets zero use.

They now want to close down this off-road park, to preserve the land for future use. They're finding rare special lizards there. A rare butterfly. Who knows. People are starting to think they import these things and then "find" them and use it as an excuse to close the place down.

Thousands of people have enjoyed this off-road park on their dirt bikes for decades. But now leftists want to preserve it for future generations, damn the current ones. As if the other 99.9% of dirt hills around the off-road park aren't enough.
To be fair, pre-amdgpu, nvidia's proprietary linux drivers were sadly an exceptional "supported" situation.

Back then it was basically just Intel's integrated graphics that had first-class mainline support. The AMD linux support is a relatively recent shift historically speaking.

Intel really should get a lot more recognition for its mainline Linux graphics support though. Without their contributions over past decades we might not even have a modern graphics stack at all in-kernel.
No, I think it's inconsiderate to text people when they are likely sleeping. If you have kids/family you typically don't silence your phone at night in case there's an emergency. So if I get a text at 03:00 I'm likely to wake up and look at it.

You're the one sending the message, so you're the one who should wait to do it when it it will be convenient for the recipient. If you're texting me in the middle of sleeping hours, you're telling me that your convenience is more important to you than mine.
Writing is what would answer the question “what are you thinking?” in ordinary circumstances.

I draw and play music too. Sure, in an architecture office, a drawing would be a conventional answer. So would three chords in a rehearsal space.

But in normal circumstances, like these, writing is how we express thoughts. You didn’t respond with a link to SoundCloud or a hosted jpeg.

I get what you are saying. And I am not arguing that writing is the best way of thinking or the only way.
