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 🙃

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)

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.

@rdg Yeah KiCad 7 has a bunch of themes to play with :-)

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!

Google is implementing a universal web DRM system: https://arstechnica.com/gadgets/2023/07/googles-web-integrity-api-sounds-like-drm-for-the-web/2/ Making it even a little worse, Google will control the software and the data. But don't get distracted by evil details - the worst thing about this scheme is that it is DRM.

@petrichor Is there a problem with org-mode (including its own noweb features) if you don't need to collaborate with non-emacs-users? Can export to pretty "read-only" formats (although it has a habit of missing code block names and other key info... that stuff need configuring).

Jupyter is great for exploratory work but requires some mental gymnastics to use for a reproducible report as it's evaluated top to bottom, so you're forced to write the report in the order the code needs to be executed, not the order you want humans to read

emacs org-mode is perfect for me but requires everyone else to install emacs, which may or may not be desirable 🙃

Rmarkdown comes close but support for languages other than R is second-class

noweb still works but it's showing its age!

I think what makes the learning curve of #3D modeling & animation software like #blender seem steep even for many seasoned #vfx designers is similar to what makes #emacs appear to have a steep learning curve even for many seasoned programmers: it's more about "learning to drive" than about learning the program's pleathora of features.

once you learn to drive in either emacs or blender, which essentially boils down to learning keyboard macros and how they makeup a tactile vocabulary with similar variations extending across a large number of "modes", you'll never again wind up spending half an hour figuring out how to edit your file again, those little things that initially steer people away from plunging in and reaping the benefits. but really that passes within about a month, and like being able to drive a bike or a car, the mobility offered by "putting in the work" lasts a lifetime.

@hyde Here's the keymap file. https://github.com/ajjackson/qmk_firmware/blob/ferris-mod/keyboards/ferris/keymaps/ajjackson/keymap.c

Not as many layers as one would think! The pink keys tap for tab, backspace, space, return and hold for "lower", alt, alt and "raise". Most symbols are on "lower", numbers and arrows/navigation are on "raise".

F-keys are rarely used and need to be "led" with a key on "lower".

ctrl, shift, super are on home-row both sides and double as letters.

Weekend project! #diy #mechanicalkeyboards
This is a Ferris Sweep with some small tweaks, mounted on a couple of camera tilt adaptors.

My first custom PCB, with help from a colleague. Good practice for more #synthdiy?
