SSL Certificate With Gandi

Generate Signing Certicate Request

With current private key (preferred for Certificate Pinning):

$ openssl req -new -key example.com.key > example.com.csr 
You are about to be asked to enter information that will be incorporated
into your certificate request.

What you are about to enter is what is called a Distinguished Name or a DN.

a = 1
b = nil

c = a and b #(c = a) and b
=> c = 1

c = a && b # c = (a && b)
=> c = nil

Yarn link packages dependencies

If you have a react project that depends on a package and you need to update your package, keep reading! This article will not talk about example folder created with create-react-library.

We are building a simple React App that will have only one component that take a string as props and display the reversed string. Then adding a new Component that take a sentence and reverse the words inside the sentence.

Not very usefull but easy example to get started with dependencies.

# fetch data from master
git co master
git pull origin master

git co feature/branch
git rebase -i diverged_commit

# Keep only the first commit (the upper one, dont know why...)
