How to use this gist

You've got two main options:

If you're using a high-end bluetooth headset on your Macbook Pro it's likely your mac is using an audio codec which favors battery efficiency over high quality. This results in a drastic degradation of sound, the SBC codec is the likely culprit, read more about it here.

Find out what codec you're using

Play a song on your headphones
Option (⌥) click the Bluetooth button at the top of your screen
If you're using AAC or aptX, you can stop here—those are the highest quality codecs.

Change your codec to AAC or aptX

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.

Headless Ethminer (nVidia) Setup Guide

Cian Johnston, July 2017

WARNING: THESE WORDS ARE OLD AND MAY NOT WORK FOR YOU IN THESE NEW AND INTERESTING TIMES.

A couple of weeks ago, I decided I should put my gaming rig to work crypto mining. I did not expect to make any significant profit on this, it was more of a fun project to set up. However, there were a large number of tutorials and guides already out there, and many were more than a year out of date.

This guide assumes the reader already has a crypto wallet set up, is comfortable with Linux and the command line, and knows how to use Google if they run into problems.

The end result is an Ubuntu 16.04 LTS headless server running CUDA ethminer via systemd.
