`$HOME`, Not So Sweet `$HOME`

Preface
1 What is $HOME to you?
2 Setup
- 2.1 Linux
2.1.4 xdg-user-dirs

local streaming test with HLS low latency tools

Install tools

https://download.developer.apple.com/Developer_Tools/HLS_Low_Latency_Beta_Tools/LowLatency_HLS_Prerelease_Tools73.dmg

Start web server

go run /usr/local/share/llhlstools/ll-hls-origin-example.go -dir /Library/WebServer/Documents -http :8000

Using GitHub Codespaces is my new default for editing a static Jekyll site

Navigate to a repo where you have your Jekyll static site (maybe your GitHub pages site)
Launch Codespaces (Code button -> Cloud -> New codespace on current branch)
Once it's launched, run the following in the terminal

gem install bundler jekyll
bundle update
bundle exec jekyll serve

Configuring Emacs for react, es6, and flow

For a while, JSX and new es6 syntax had flaky support in emacs, but there's been huge work on a lot of packages. Using emacs for JavaScript with React, ES6, and Flow (or Typescript, etc) is really easy and powerful in Emacs these days.

This is how you can work on modern web development projects with full support for tooling like JSX, Flow types, live eslint errors, automatic prettier.js formatting, and more.

Set up `web-mode`

web-mode provides most of the underlying functionality, so a huge shout-out to the maintainer(s) there.

	# synthio_midi_synth.py - pretty usable MIDI-controlled synth using synthio in CircuitPython
	# 11 May 2023 - @todbot / Tod Kurt
	# Uses cheapie PCM5102 DAC on QTPY RP2040
	# Video demo: https://www.youtube.com/watch?v=N-PbbWWDE6k
	# Features:
	# - midi velocity controls attack rate (gentle press = slow, hard press = fast)
	# - notes have small random detune on all oscillators to reduce phase stacking
	# - adjustable number of detuned oscillators per note 1-5 (midi controller 83)
	# - five selectable waveforms: saw, squ, sin, noisy sin, noise (midi controller 82)
	# - vibrato depth on mod wheel (midi controller 1)

	## Will successfully install amdgpu drivers and rocm,
	## but pointless as there is no gpu device attached to WSL2 (only CUDA and DirectML is supported, not /dev/kfd or amd gpus)

	## ROCM/HIP

	sudo apt update

	Since mopsled didn't renew their domain, this is from their original blogpost which was a useful reference:

	NearlyFreeSpeech.net (NFSN) is a very inexpensive web host, DNS provider and domain registrar. NFSN added support in 2014 for NodeJS, Django, and tons of other languages through persistent processes. This guide, based on the Django tutorial provided by NFSN, will demonstrate the setup I used for creating a node.js daemon.
