My hundred struggles while using Linux as my desktop driver (Ubuntu 24.04)

Hi! On Thursday 25 April 2021, I entirely switched from macOS to Linux: https://maelvls.dev/evolution-of-my-home-office/. I took note of every adjustment I had to make along the way. I use Ubuntu "vanilla" (with Gnome as my desktop manager).

🔥 Update 26 June 2023: I am abandoning "desktop" Linux! I can't bear having to work around everything all the time, not even counting the tons of problems that occur whenever I do a major version upgrade (e.g., when I upgraded from 21.10 to 22.04, my PPAs broken obviously, and also I lost all the hack I had made to the /etc to work around problems). I am officially back to macOS starting 26 June 2023. I'll still use my Linux workstation remotely over Mosh, but not as a desktop environment.

To smoothen the transition, I use the following hacks on macOS:

Linear Mouse since I can't stand macOS' mouse acceleration and also to fix my mouse wheel's direction. My config:

Implementation notes on react's scheduling model as of (shortly before) 16.8.0

While the public API intended for users to use is the scheduler package, the reconciler currently does not use scheduler's priority classes internally.

ReactFiberScheduler has its own internal "mini-scheduler" that uses the scheduler package indirectly for its deadline-capable scheduleCallback.

This is kind of a documentation of implementation details that I suppose will be gone by the end of the year, but what can you do.

Disabling GNOME Tracker and Other Info

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/

After discovering it chowing 2 cores, I decided to go about disabling it.

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
