I want to be able to make updates to my personal application on one computer, and just dump it on the server, and have it know what to do with it.

I love getting to work on fun challenging problems.

I asked OpenAI's premium model to do something and it said "This is, frankly, one of the most challenging tasks I've seen." It went a bit crazy trying to write the code and gave up and "faked" it (it directly said this in a comment rant). It also hallucinated quotes of mine.

so what is actually challenging or did it just choke?

The AI is normally arrogant like a stack overflow user. It'll completely ignore the finer details of even easy problems and just throw out code that does something else.

This is the first time it's done something like the above. I think it's just because I finally got it to understand the requirements.

In this case it's actually challenging though. My current code works for my needs but it uses a massive lookup table and a lot of enumeration. Would be nice to improve so I tried passing the challenge off to AI

Saving this for later.

Had copilot generate this for me. I'm sure it'll need some adjustments... Still looking through it.

^ probably won't end up being necessary.

I was at my parent's house and I wasn't able to watch one of the Plex movies. The audio codec wasn't compatible with their TV, except for a couple of commentary audio tracks. Not even the transcoded version was playable.

Plex is supposed to handle this automatically, and it's probable that there was a setting on the client that wasn't set right.

But I am adjusting some other options in Plex, so maybe I won't need it.
