That one isn't an example of this. It is actually a Windows Subsystem (at least WSL1) that exposes Linux syscalls, so is for Linux userspace programs. There is also the Windows Subsystem for Win32 and there used to be a Windows Subsystem for Unix. Linux Subsystem would be completely wrong, because it is a Subsystem of Windows not of Linux.

No it wouldn't. Following the scheme a couple of comments above, we have: Y of X providing Z - Windows Subsystem for Linux. Y providing X on Z - Linux Subsystem for Windows. The former is "for [having]", the latter is "for [use on]".

I still would expect it to be something running on top of Windows, not a part of the NT kernel. Subsystem is a specific term for a core concept of the NT kernel here, so no it wouldn't make sense to call it LSW.

MS has some confusing naming, this isn't one of them.

So, chewing on beetle exoskeletons would repair teeth enamel? Wonder if there is archaeological evidence of humans doing that. Edit: there seems to be plenty of evidence of eating insects but any dental association is probably incidental (pun not intended). Maybe we just haven’t been looking into the enamel for these structures.

Did past humans have the dental problems we have? I imagine a lot of our problems are caused by our diet and access to sugar.

It's not just sugar, starchy foods like bread, potatoes start breaking down quickly right in the mouth into simple sugars, it's enough that white bread has a higher glycemic index than actual sugar :)

Never in History have humans had as good teeth as they do today. Also consider that until we had vaccines and antibiotics in the early 20th century, the average lifespan was very short.

Sure. We can also treat cancer better than ever before, but it would still be interesting to know where the rise in cancer cases came from, even if we can patch around the problem and are better off overall. Same for dental health: my understanding is also that people didn't used to need toothpaste to enjoy a comparable dental health

a lot of it comes from better detection as much as poor diets and very low amounts of exercise.

> Never in History have humans had as good teeth as they do today. This is absolutely untrue. What is your reference? Never in history have so many people had such "good" looking teeth, but they involve an enormous amount of prosthesis and amalgam. Veneers aren't good teeth, they're intentionally destroyed teeth used to root false teeth. And brushing, although it keeps teeth clean and not stinky, deepens the gum pock…

I'll take my bets on modern day britain having much better dental health than any other british era back to the romans. Starchy food + no brushing = bad news.

How does this compare with nano-hydroxyapatite, which is the current rage in toothpaste innovation and remineralization?

nHA is prohibitively expensive to produce and the most effective process that produces the smallest particles is patent-protected by Sangi, and therefore many nHA toothpaste brands only contain a fraction of the concentration used to produce the effective results reported in academic studies (1-2% instead of 10%). If keratin toothpastes can be produced more economically they could be a better option for mass adoption…

bah it's like $15-20 a tube that will last a couple months. That's nothing to most people on hackernews

There are lots of activities wherein a hair, pubic or otherwise, might end up in a person's mouth.

Name two.

1. Having long unsecured hair and driving with the windows down

2. Dining out at a place with low hygiene standards

3. "Dining in" ;)

More expensive than conventional fluoride toothpaste available in the US but I agree it is a small price to pay when considering the benefits

"Windows Subsystem" is a noun-phrase here though. If you want an X providing Y on Z, then it would be "Windows Subsystem for Linux on Windows"
