It seems like there are a lot of people either leaving or talking about leaving Github, a very prominent one being Mitchell Hashimoto.
Fragmentation seems inevitable, as people/companies start to distribute among the various options (Codeberg, self-host Forgejo, Gitlab, etc…).
I think the decision Hashimoto makes with ghostty will potentially set the tone for how the death of Github will happen.
I have some scattered thoughts about the situation:

Wheeled vehicles existed for 5,000 years before someone thought of running a bus service.

I went hunting for references to the OEIS in open source code, and found some weird ones.
There are not one, but two live-coding music frameworks that use OEIS sequences as a source for "anything that can be sequenced" in music. I'm guessing that's used for choosing pseudorandom melodies, interesting rhythyms, or how to overlap tracks in different ways.
The first project is called mercury, which is advertised as having "an extensive library of algorithms to generate or transform numbersequences that can modulate parameters.
