A Hacker's Guide to learning rhythm and lead guitar FAST!

I've been playing guitar for over 30 years. I never took formal lessons - only ocassional ones targeted to a specific topic. I love the discovery process and the relationship I've created with the instrument.

Five years ago or so, I had an a-ha moment, which fundamentaly changed the way I approach my learning of the guitar. After internalizing all the content I consumed, I thing I've come up with a formula for learning both rhythm and lead guitar in a very streamlined and systematic fashion. This method will teach you how to find chords across the entire fretboard so you can create chord progresssions for your own songs, or to make it easier to figure out the chords of your favorite songs.

However, what I like the most about it is that it gets you ready to play lead guitar, without putting too much emphasis on the pentatonic scale. Also, it teaches the guitar from the standpoint of understanding its symetry, and dare I say, the mathematics

Handling Multiple Github Accounts on MacOS

The only way I've succeeded so far is to employ SSH.

Assuming you are new to this like me, first I'd like to share with you that your Mac has a SSH config file in a .ssh directory. The config file is where you draw relations of your SSH keys to each GitHub (or Bitbucket) account, and all your SSH keys generated are saved into .ssh directory by default. You can navigate to it by running cd ~/.ssh within your terminal, open the config file with any editor, and it should look something like this:

Host *
 AddKeysToAgent yes

> UseKeyChain yes
