Installing and configuring Powerline-style command line tools for developers (OSX)

Intro:

For every developer, terminal is their weapon, so why don't you customize it to become a powerful, and a beautiful weapon?

Powerline style refers to a terminal style that helps developer to keep track of their workflow easily, allows them to have perfect visual on current directories and new changes. It is also git recognizable, and failure detector that will help your development process becomes more interact and much faster.

In this guideline, I will introduce you with 2 smart shells: Zsh and Fishshell. Both are perfect for the development jobs due to its rich of resources, and user-friendly.

Note:

I am assuming you are here because like me, you installed a bazillion different python interpreters on mac and the whole thing is a spagetti. Today, I finally fixed my python installation. Whatever I install for python2 or python3 using pip JUST.WORKS.. My god! finally.

What the hell?

Here is what I had messed up, which you also probably did:

I had too many different python interpreters
Too many different symlinks which I lost track of
almost no package I installed with pip worked without a headache
any attempt to fix using online resources made it worse.

Learning how to use Dagger2

When learning to use Dagger, I think a large part of the difficulty arises from the fact that there are A LOT of articles out there explaining how Dagger works, which can be confusing in itself when trying to synthesize all the knowledge. One issue is that the example projects are wildly different in terms of organization and practices used. Another issue is the variance in Android version used, and so some resources may use outdated libraries and practices.

Adding to the confusion, somewhat recently a few Android-specific Dagger packages were introduced, which added some improvements to how it's used on Android. This means that there are articles dealing with the OLD method of using Dagger as well as articles dealing with the NEW way. This confused the hell out of me when I was trying to learn it.

Having come out on the other side of the confusion, the following are the resources I would recommend to anyone trying to learn Dagger from scratch.
