Moaan InkPalm Plus setup

I got this device set up nearly as I like, but then flew too close to the sun while experimenting with setting lock screen wallpaper and enabled a lock screen PIN which was then never accepted. After a reboot recovery in adb, if you hold the top button and press the volume up button, you can get to a menu where you can do a factory reset.

After I did that, I decided to write this down.

The firmware version this has now is: MAS_EPD305_L81B804_T44_V09.

Setup from factory reset

How to use:

./wordle.sh

Or try the unlimit mode:

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

Python3 Virtualenv Setup

Requirements

Python 3
Pip 3

$ brew install python3

Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

	#!/bin/bash
	set -x

	## 1. install required dependencies with apt
	apt update && apt install python3-venv python3-dev libffi-dev libssl-dev

	## 2. create directory for docker-compose's virtualenv
	mkdir -p /opt/local/docker-compose
