drdirk··on My MacBook Keyboard Is Broken and It's Insanely Expensive to Fix
My MacBook Pro M1 keyboard repair costed >700€, this is not a butterfly keyboard. So also new models have an expensive keyboard replacement.

My previous MacBook Pro keyboard was a butterfly keyboard and also broke, but got replaced for free. I don’t feel I am a heavy user as the MacBook Pro is mostly connected to an external keyboard and am pretty annoyed by apples keyboard quality (based on my sample size of 2).

drdirk··on Should you take creatine?
When I first took creatine from an Amazon dealer I had gut problems. I later bought a "micronized" creatine (similar to https://bulevip.com/es/3418-optimum-nutrition-creatina-powde...) and did not experience any gut problems. Taking the same product now for 3 years. Inbetween I used some other variant from time to time and have the theory that some vendors sell a not clean product that interferes with your gut.

In the web version it is unavoidable only in the native app you can change to the original audio.

P.S. I uninstalled the YouTube app because of YouTube Shorts and had to reinstall the app to listen to videos in the original audio.

drdirk··on LLMs Unleashed: The Power of Fine-Tuning
Both can be done. Fine-Tuning the prompt is cheaper and can be done on consumer hardware. Fine-tuning the LLM model weights is expensive and needs cloud support.

You would expect this kind of theft to be happening only in Lebanon, but here in Barcelona (Europe) I see the metal covers missing regularly too.
