You need to take a larger dose. Your muscles absorb it first, so you end up needing to take a lot more to get it to your brain cells.

No, elevated creatinine levels is only a sign of kidney disease if all else remains equal. Consuming more creatine will naturally increase production of creatinine because creatinine is a byproduct of the kidneys processing creatine.

In other words, it's not a very reliable signal for kidney disease. There is a more reliable blood test called a "Cystatin C" test.

Just out of curiosity, were those creatine supplements pure creatine? Or were they workout supplements that might have also included caffeine or other things?

TBH this sounds like it could be entirely unrelated to creatine. It just sounds like you have shedding and thinning without Minoxidil and Finasteride, and it stops when you start taking them again.

> At one point I stopped Mino and Fin, but kept the creatine and the shedding increased rapidly.

I think it's a common for shedding to accelerate after stopping Minoxidil.

Not sure about the "kind", but minoxidil works by increasing blood flow to hair follicles. So if massages can have a similar effect, I don't see why it couldn't help.

I've also read that maybe massaging the muscles around the scalp to loosen it might help. E.g., a scalp that's too tight can have detrimental effects on the hair follicles.

That being said, I don't know what kind of evidence there is to support either of those things. Seems like a safe enough thing to try though.

I've found it helps cognitively if under a lot of stress and/or sleep deprived. If I'm not especially stressed and am well rested, I don't know that I notice any difference.

There's a difference between having built up intuition through experience about how to play chess, and figuring out how to encode that information in a program. In other words, the amazing chess player can probably provide valuable insight into any given board position, but they may struggle to generalize that insight.

I've yet to see AI be good at extracting good abstractions. More often than not it jumps to creating a battery of special case checks.

> The one place in my usage where it doesn't match Samba rsync is with the following:

This appears to match "normal" `rsync` behavior as well. I think you need a trailing slash after `services` to sync only the contents.

EDIT: actually my "normal" rsync is openrsync on macOS...

I suspect a blindfolded passenger might prefer the Sienna. I can imagine it might be easier to get carsick blindfolded in a 911.

But also, as a driver, there is a clear difference between a Sienna and a 911. The differences are objective, but of course the preferences are subjective.

The entire discussion was centered around whether or not using AI to detect AI content would work, or if it would create false positives that harm human content creators.

It could work "well enough" for YouTube to consider it a success while still harming a fairly large number of content creators.

> All they need to do is "randomly" label 99,999 of every 100,000 as AI and they'll be right 99.999% of the time.

Unfortunately that could still be true while labeling all human-crafted content as AI-created.

What makes you think demand won't drive those prices up as well? And this is more than just gaming, the Steam Deck prices are increased due to the increase cost of general components like RAM, which impacts machines used to do work as well.
