Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

First of all, install Homebrew itself.

As the tap is a private Git repo, you need to generate a GitHub token with repo scope and then add this token to your ~/.netrc file like this:

machine github.com
  login <your GitHub user>
  password <your GitHub token>

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.

$ git clone https://git.samba.org/samba.git
$ brew install jansson
$ brew install readline && brew link --force readline
$ cpan # then w/in cpan install Parse::Yapp module (might be 'install Term::Parse::Yapp')
$ brew intsall libarchive
$ export LDFLAGS="-L/usr/local/opt/libarchive/lib"
$ export CPPFLAGS="-I/usr/local/opt/libarchive/include"
$ ./configure --prefix=/opt/samba --without-ad-dc --without-acl-support

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
	# see: ss64.com/bash/syntax-prompt.html

	if [ $# != 2 ]; then
	echo "Usage: $0 /path/to/input_ipa /path/to/output_ipa"
	exit 1
	fi

	if ! [ -f $1 ]; then
	echo "'$1' does not exist"
	exit 1
	fi
