sudo apt install zram-config, this will install several files, including systemd startup /etc/systemd/system/multi-user.target.wants/zram-config.service
sudo nano /usr/bin/init-zram-swapping and edit:

#!/bin/sh

# load dependency modules
NRDEVICES=1
if modinfo zram | grep -q ' zram_num_devices:' 2>/dev/null; then
 MODPROBE_ARGS="zram_num_devices=${NRDEVICES}"

To scan all channels

To use pip, you must be running Jython v2.7.1 (downloaded from here: http://search.maven.org/remotecontent?filepath=org/python/jython-standalone/2.7.1/jython-standalone-2.7.1.jar). This is not compatible with Esper, so be sure to remove all of these files before upgrading, ie:

rm -rf ./automation/jsr223/000_components/000_Esper.py ./automation/lib/python/esper

With v2.7.1 installed, we can run the Jython from the openHAB installation to install pip

java -jar /openhab/conf/automation/jython/jython-standalone-2.7.1.jar -m ensurepip

Recovering the BIOS password from a Panasonic CF-U1 mk2 (AMI Aptio UEFI)

A mess of my own making

While messing with a CF-U1 handheld PC that I bought off ebay I managed to mess up the BIOS and it seems it reverted to previous settings which included an unknown BIOS password, it would however still boot into windows. Since I could still boot windows I was able to dump the bios flash using AFUWINGUI.EXE the version I used was 3.09.03.1462 which is available here:
https://www.ami.com/support-other/ Click on Aptio 4 AMI Firmware Update Utility

The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.

BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:

$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.

then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:

	#!/bin/bash -ex

	# Build a new Centos8 install on EBS volume in a chroot
	# Run from RHEL8 or CentOS8 instance - eg: ami-0c322300a1dd5dc79 in us-east-1 (RHEL 8 official image)
	# Script expects a second EBS volume, I add them as /dev/sdf in the console
	# When the script completes, turn the second EBS volume into your new AMI through the console.

	# Adjust the section below to match the device names you're using. Defaults are for an m5.large

	# m5 series requires the updated device names

	#!/bin/bash
	# As described in https://bugs.launchpad.net/bugs/1766076
	### Installation Instructions:
	# 1. Install file into `/usr/local/bin/reset-tb`
	#
	# 2. Optional: allow password less sudo by creating a file `/etc/sudoers.d/allow-reset-tb` with the following content:
	# ----8<-----
	# <your username> ALL = NOPASSWD: /usr/local/bin/reset-tb
	# ----8<-----
