Install ElementaryOS Juno on SecureBoot + EFI enabled computer

Yet another night passed to fight with the machine. 💪

I was really happy to know that the latest version of ElementaryOS were out so I could not wait to install it on my latest laptop Acer Predator. 🤘 But... as usual, it was not without troubles...

Compatible with SecureBoot + EFI enabled computers? Awesome!!

But not really in fact... It might work for some brands but for my Acer Predator... not at all. Well it can work but will requires the steps explained below.

Install pip sudo apt-get install python-pip
Install powerline sudo pip install powerline-status
Install fonts sudo apt-get install fonts-powerline
Add these lines to respective files:

.vimrc > set rtp+=/usr/local/lib/python2.7/dist-packages/powerline/bindings/vim/

Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

	#!/usr/bin/env -S bash -c "docker run -p 8080:8080 -it --rm \$(docker build --progress plain -f \$0 . 2>&1 \| tee /dev/stderr \| grep -oP 'sha256:[0-9a-f]*')"

	# syntax = docker/dockerfile:1.4.0

	FROM node:20

	WORKDIR /root

	RUN npm install sqlite3

	CC = gcc
	RM = rm -f

	INSTRUMENT_FOR_PROMETHEUS := false

	ifeq ($(INSTRUMENT_FOR_PROMETHEUS),true)
	CFLAGS = -Wall -DINSTRUMENT_FOR_PROMETHEUS
	LIBS = -lbcm2835 -lprom -lpromhttp -lmicrohttpd
	else
	CFLAGS = -Wall
