Works for Thinkpad X1 Yoga 2G (20JDCTO1WW) (and most probably others) with OLED display

First install inotify-tools. Then create a script around inotify that will be launched upon each boot or through autostart.

sudo apt install inotify-tools
cat <<-EO1 | sudo tee /usr/local/bin/xbacklightmon.sh#!/bin/bash
    # https://wiki.archlinux.org/index.php/backlight#sysfs_modified_but_no_brightness_change
    # https://wiki.archlinux.org/index.php/Alienware_13#OLED_screen_brightness
    # https://gist.github.com/lalten/ce5ac0b1cc4b24a24cc44926255b871d

apt install inotify-tools

YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

Add the following line in `/etc/dnsmasq.conf`

dhcp-script=/etc/detect_new_device.sh

Setup sendmail to send email to your text number.

Goal: run a simple NodeJS application inside a Docker container

Subgoal: give it access to local files.

docker run -it --rm --name example -v "$PWD":/usr/src/app -w /usr/src/app node:5-slim node index.js

output:

Password-store keeps your passwords (or any other sensitive information) saved in GnuPG encrypted files organized in ~/.password-store. For more information about GPG, consult the GNU Privacy Handbook.

Getting started

To get started, install pass and generate a keypair.

$ brew install pass
$ gpg --gen-key
$ gpg --list-keys
