Introducting "keynum" - a concise alternative to enum

Introducting "keynum" - a concise alternative to enum

The problem with regular enums

Standard enums in JavaScript require verbose syntax for checking their value:

const STATE = {
  WAIT  = 1,
  READY = 2,
  IDLE  = 3
};

p10k tmux window list

Display your tmux window list directly in your terminal prompt, eliminating the tmux status bar.

Adds an additional powerline10k right prompt containing the window list from your tmux status

Note

Terminal prompts only update when you press enter, so you may see an out of date window list

Actually Disabling Bluetooth Autoconnect on Startup in Windows

Actually Disabling Bluetooth Autoconnect on Startup in Windows

Situation

I use multiple devices with my bluetooth earphone connected to my mac machine, phone, or tablet.
When I boot my windows machine, it automatically connects to and snatches my bluetooth earphone. This is very annoying.

Results from google on ways to disable this are unhelpful:

  • Unpair the device (???)
  • Disable bluetooth support system service via services.msc
  • Disable the device via Device Manager

Electron is tricky to get set up on Windows Subsystem for Linux, but it can work!

Four things needed overall:

  1. you need WSL2, not WSL1
  2. you need node, of course, and that part isn't so bad
  3. you need to apt install several dependencies
  4. you need an X Server so it can display the electron GUI over in Windows-land

Setup instructions, in order:
