Need

Convert .mov/.MP4 to .gif

Reason

As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.

This is not limited to developer, anyone has this need can use this method to convert the files.

	# some tips: https://wiki.archlinux.org/title/NFS/Troubleshooting#Unable_to_connect_from_OS_X_clients

	sudo apt install nfs-kernel-server
	sudo chmod 777 /my/shared/dir

	# edit /etc/exports and add:
	/my/shared/dir <client ip address>(rw,sync,all_squash,subtree_check,insecure,anonuid=0,anongid=100,crossmnt,fsid=0)

	sudo exportfs -a && sudo systemctl restart nfs-kernel-server

	Based on https://www.thinkwiki.org/wiki/How_to_control_fan_speed

	Steps:

	- Install Thinkfan https://github.com/vmatare/thinkfan
	- Add `options thinkpad_acpi fan_control=1` to `/etc/modprobe.d/thinkpad_acpi.conf` (Debian Bullseye, testing)
	- Add the following content to `/etc/thinkpad.conf`

	# All core sensors + ACPI
	sensors:

	# create rake task with the following content

	namespace :spec do
	namespace :templates do
	# desc "Copy all the templates from rspec to the application directory for customization. Already existing local copies will be overwritten"
	task :copy do
	generators_lib = File.join(Gem.loaded_specs["rspec-rails"].full_gem_path, "lib/generators")
	project_templates = "#{Rails.root}/lib/templates"

	default_templates = { "rspec" => %w{controller helper integration mailer model observer scaffold view} }

	# frozen_string_literal: true

	require 'zeus/rails'

	class Pry::Pager
	def best_available
	NullPager.new(pry_instance.output)
	end
	end

	#!/usr/bin/env ruby

	def with_captured_stdout
	old_stdout = $stdout
	$stdout = StringIO.new
	yield
	$stdout.string
	ensure
	$stdout = old_stdout
	end

	Download the Debian firmware package corresponding to your hardware (ex. https://packages.debian.org/sid/firmware-iwlwifi)
	Open the data archive inside it and put the content of `lib/firmware/` into the root directory of your FAT USB device
	Insert the USB device if the installer asks for it, switch via Ctrl+Alt+F2 to a virtual terminal and mount your device to `/lib/firmware/`, e.g. by using mount `/dev/sdb1 /lib/firmware`
