I mean, "patches welcome" is a bit pointless when there is nothing to patch, is

Really, we're not pushing back on ideas, we're just saying that this is
something has happened before ("open up your scripts so we can
reuse/improve") and getting nowhere.
include anything related to AUTOSEL. It seems AUTOSEL is still closed source.
Not as much as closed source as a complete mess on a VM I'm afraid to
lose.
I didn't really want to try and invest the effort into extracting it out
becuase:
1. It's one of the first things I did when I started learning about
neural networks, and in practice it's inefficient and could use a
massive overhaul (or rewrite). For example, it currently has ~15k
inputs, which means that it needs a beefy GPU to be able to run on (it
won't run on your home GPU)..
2. At that time I wasn't familiar with coding for NN either, so it's a
mess of LUA code to run under Torch (yes, not even pytorch).
3. It's very tied to how VMs on Azure operate, and could use a lot of
abstraction.
So really, I'd much rather invest effort into rewriting this mess rather
than digging it out of the crevices of the VM it's sitting in.
BTW, I already did something similar "off to the side" a few years ago when I
wrote a script to keep track of and prioritize syzbot reports from
https://syzkaller.appspot.com/, and generate per-subsystem reminder emails.
I eventually ended up abandoning that, because doing something off to the side
is not very effective and is hard to keep up with. The right approach is to
make improvements to the "upstream" process (which was syzbot in that case), not
to bolt something on to the side to try to fix it after the fact.
So I hope people can understand where I'm coming from, with hoping that what the
stable maintainers are doing can just be improved directly, without first
building something from scratch off to the side as that is just not a good way
to do things. But sure, if that's the only option to get anything nontrivial
changed, I'll try to do it.
Eric,
Did you consider working to improve or add functionality to b4?
FTR, I'm happy to shift investment into tooling for stable maintenance
into b4.
