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

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse

All Objective-C Exceptions
    // Catches exceptions thrown by Objective-C code.
    // Default Xcode breakpoint created by clicking "+" to add breakpoint -> "Exception Breakpoint".
    // Change "Exception: All" to "Exception: Objective-C".
    
-[UIApplication main]
    // Helps when printing objects via the debugger by making it aware of the classes in UIKit.
    // Symbolic breakpoint created by clicking "+" to add breakpoint -> "Symbolic Breakpoint".
    // Enter "-[UIApplication main]" for the Symbol.
    // Choose Action -> "Debugger Command".
