What about Hydroxyapatite?

https://en.wikipedia.org/wiki/Hydroxyapatite

Anyone on this stuff? I want to take a break from fluoride paste.

I've been enjoying using this over the past 3 weeks.

This is nano-hydroxyapatite, meant to be more effective than hydroxyapatite alone.

Doesn't xylitol gum do the same thing? Re-mineralize teeth?

tomdekan · a month ago

Xylitol reduces cavity‑causing bacteria and raises salivary flow, which can increase calcium and phosphate availability. That environment supports natural remineralisation and boosts the effect of fluoride or hydroxyapatite products, but xylitol itself doesn’t deposit minerals into enamel.

For actual mineral replacement, look to fluoride toothpaste/varnish, casein phosphopeptide‑amorphous calcium phosphate (CPP‑ACP), or nano‑hydroxyapatite formulations; xylitol gum is a useful adjunct.

Post on Reddit showing many women as upset by OpenAI's new models. They viewed the previous models in ChatGPT as their boyfriends. With the new models, they now feel that their partner has been "taken from them".

Oh the Unsloth dynamic ones are not 2bit at all - it's a mixture of 2, 3, 4, 5, 6 and sometimes 8bit.

Important layers are in 8bit, 6bit. Less important ones are left in 2bit! I talk more about it here: https://docs.unsloth.ai/basics/unsloth-dynamic-2.0-ggufs

Thanks Daniel. Do you recommend any resources showing the differences between different quantizations?

This assumes there are compelling alternatives in the market that I can choose from. In reality, there are only a few entrenched players in any established market that work hard to limit competition. So yes, even if I'd like to choose not to hand over my hard-earned money to Evil Corp #93, I can only do the "stupid" thing and watch myself and my environment get exploited.

Also, I don’t think my previous comment does assume that there are compelling alternatives.

A person always has a choice not to spend their money. Even if they need expensive healthcare, they can choose not to buy it. By buying the product, they want the service more than their money.

They might think that the price is too high, but prices are a function of market forces.

It doesn’t make sense to me that a person can say they feel exploited because they have voluntarily chosen to buy at a particular price. They probably want to pay less, and might feel that the consumer surplus is low, but they still value the service more than their money. That isn’t exploitation to me.

I disagree with the general comment that “any established market” has “only a few entrenched players”. I’d say that most markets provide compelling alternatives. Where they don’t yet, the product is either a commodity, or there is an opportunity for a new business to serve the customer!

But let’s say your point is true. How do those players become entrenched? I’d say it’s from providing great value.
