Notes on Modern UI Development: Taking Ideas from Spaced Repetition

Introduction

I have been working on a modern typing training application for the last couple of days. One of the main motivations was to build an app with a modern UI and minimal distractions, enabling to fully focus on the training aspect. You can read more about the original idea and thought process here as well as some notes on iterating over the details here.

After adding some minimal auto close functionalities for the code training section, you can read about it here, another important feature was to make the text training part more entertaining.

Apple Borked my Nix!

Ok, so you've had nix (home-manager) working fine. Then Apple tells you it's time to update.

Ok. Reboot. Oops. It has now broken your Nix setup. Here's some stuff to work through. YMMV.

Note: This is what worked for me, who was just using nix + home-manager. The upgrade that I last did that caused all these issues was 12.3.X > 12.4

Visual Studio Code and C# code completion and debugger for Godot

Ok, this is a quick document to guide you through the setup of a Godot project in Visual Studio Code.
I'll assume you have a working C# environment installed. Note that on Linux, you might need to install Mono for everything to work fine with Godot 3.x.

1. Install the necessary extensions

First off, make sure you have the following extensions installed and active in Visual Studio Code:

C#

brew install minikube
brew install hyperkit
minikube config set driver hyperkit
minikube start --memory 8192 --cpus 5 --disk-size=80GB

brew install docker
# point docker to the minikube env
eval $(minikube -p minikube docker-env)
# validate setup

About

I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

On WG server, I started an iperf3 server
On WG peer, I wrote a script that does the following:
- wg-quick down wg0
Edit MTU in the /etc/wireguard/wg0.conf file

	# launch daily notes with `notes`
	# launch specific notes with `notes woodworking`
	# this is a cloud synced file, so it's live on all my devices
	function notes(){
	SUBJECT="${1:=daily}"
	if [ -z "$SUBJECT" ]
	then
	(cd ~/Documents/notes && hx NOTES.md)
	else
	(cd ~/Documents/notes && hx "${SUBJECT:u}.md" NOTES.md)
