Today I built a fiddly academic physics/ML package in a Podman container and just exfiltrated the results of interest using `podman exec` and `podman cp`. It was... quite a nice workflow?

Feeling vaguely stupid for all the pain I went through previously with volume mounts and permissions ๐Ÿ™ƒ

So far: polished frets, clean/oil fretboard, restring with Beefy Slinky (i.e. .011" set), tune to C-standard, play with saddle height and truss rod.

It looks like the fret buzz goes away with a slightly higher action and more relief (neck curvature). Previously the neck was almost straight.

I think the limiting factor now is some high/low frets, and wear in lower frets. It may be possible to improve things with a fret level, but that involves buying tools and taking risks!

Realised I haven't been playing my first guitar much lately, due to a) weight [thinline is so comfortable!] b) fret buzz and intonation woes.

Let's try and rehab it as a doom machine. That would ultimately mean new pickups but it's a waste of money if the thing isn't playable first.

Oh my, this stirs up some feelings! Nostalgia^2

Here are a few things I find interesting in #Python 3.11 (aside from the improved speed)

1. FINALLY, the Self type

from typing import Self
class Cat:
def demand_food(self) -> Self:
print("Meeooow")
return self

2. TOML parsing

import tomllib
with open("config.toml", mode="rb") as f:
config = tomllib.load(f)

I'm not expecting any real privacy for stuff i post on followers-only given that i accept almost every request, but learning that gnu social follows straight up publish on a search-indexable page anything i post on priv was a real Fedi Moment
Update: after reading more datasheets I have a better idea of how these comparator chips work! a) The cheaper LM339N should work just as well as LM2901 b) High output is high-z / disconnected, while low output pulls to negative rail. It needs a pull-up resistor to function properly. c) My design has changed again, to run the CMOS logic in a goofy -12V/GND range and later invert back to a positive output.

Have been thinking for a while about some CMOS-based counting/logic modules for my #eurorack #diy #synth ; need to present high impedance to +/-12V continuous input and feed high-impedance 0-5V logic. After a lot of permutations, I think this design will be cheap, compact and power-efficient? The goofy part is that the comparator runs off the -12V and +5V rails!
