How To Work With Multiple Github Accounts on a single Machine

Let suppose I have two github accounts, https://github.com/rahul-office and https://github.com/rahul-personal. Now i want to setup my mac to easily talk to both the github accounts.

NOTE: This logic can be extended to more than two accounts also. :)

The setup can be done in 5 easy steps:

Steps:

Step 1 : Create SSH keys for all accounts
Step 2 : Add SSH keys to SSH Agent

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

How to develop with Jetpack locally with ngrok

To connect Jetpack in your local installation, you'll need a way for WP.com servers to reach your server. That can be done in a number of different ways:

You can open your router's ports and use your public IP
You can use some kind of Dynamic DNS provider.

But these options fall short of ngrok, which is a "localhost tunnel". It basically allows the Internet to hit a local port on your machine without worrying about ports or IPs.

As long as ngrok is running, Jetpack / WP.com will be able to communicate with your local site. This will allow remote modules like Site Search and Manage to work.

	tldr;
	DDD is primarily about modeling a Ubiquitous (= überall vertreten) Language in an Bounded Context.
	It avoids the design of monolithic applications.
	Use DDD when the business model complexity is high (higher than the technical aspects of the project).

	Bounded Context - semantic contextual boundary
	Within the boundary, each component of the software model has a specific meaning and does specific things
	The components inside a Bounded Context are context specific and semantically motivated.

	In the Beginning of software modeling the Bounded Context is only coceptual and is part of the Problem Space.
