#Capture and stream a webcam To capture using the iSight camera on a Mac, or infact any other webcam connected to the Mac, we can use FFmpeg. First get a list of the devices installed.

ffmpeg -f avfoundation -list_devices true -i ""

This will list the aviable video and audio devices.

The below will capture at 30fps and the set video size to a file. ffmpeg -f avfoundation -framerate 30 -video_size 640x480 -i "0:none" out.avi

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export to tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

	Notes to make IR shield (made by LinkSprite) work in Raspberry Pi 3 (bought from Amazon [1]).
	The vendor has some documentation [2] but that is not complete and sufficient for Raspbian Stretch.
	Following are the changes that I made to make it work.

	$ sudo apt-get update
	$ sudo apt-get install lirc

	# Add the following lines to /etc/modules file
	lirc_dev
	lirc_rpi gpio_in_pin=18 gpio_out_pin=17

	#!/bin/bash
	# Downloads and installs the startssl CA certs into the global Java keystore

	set -euf -o pipefail

	# Check if JAVA_HOME is set
	if [ "$JAVA_HOME" = "" ]
	then
	echo "ERROR: JAVA_HOME must be set."
	exit 1
