downgrade firmware macbook air

I finally managed to successfully downgrade the EFI firmware to version 1.6. Unfortunately that didn't make my hard drive work. However I'm going to reproduce my steps here so that the whole world can know what it takes:
Download the EFI firmware update package from Apple. Here is the link I used for firmware version 1.6 for my late-2008 MacbookPro5,1: http://support.apple.com/kb/DL746
WARNING! If you use the wrong firmware for you computer, bad things will almost certainly happen. This isn't my experience but it would probably brick your computer, meaning it will change from being a computer that can compute things to being a brick that just sits there. You have been warned!
The EFI firmware update 1.6 comes as a .pkg file. Since it won't extract for you unless your computer needs the update, you will have to extract it yourself. The best way I found

Most popular speedup sysctl options for Proxmox. Put in /etc/sysctl.d/
###
# Proxmox or other server kernel params cheap tune and secure.
# Try it if you have heavy load on server - network or memory / disk.
# No harm assumed but keep your eyes open.

# @updated: 2020-02-06 - more params used, adjust some params values, more comments on params

FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,

Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.

For ffmpeg:

Commit, clone a container

To 'clone' a container, you'll have to make an image of that container first, you can do so by "committing" the container. Docker will (by default) pause all processes running in the container during commit to preserve data-consistency.

For example;

docker commit --message="Snapshot of my container" my_container my_container_snapshot:yymmdd
