Why Multiple SSH keys?

There are numerous reasons you may need to use multiple SSH keys for accessing GitHub and BitBucket

You may use the same computer for work and personal development and need to separate your work.

When acting as a consultant, it is common to have multiple GitHub and/or BitBucket accounts depending on which client you may be working for.

You may have different projects you're working on where you would like to segregate your access.

Async Operations with useReducer Hook

9 March, 2019

We were discussing with @erusev what we can do with async operation when using useReducer() in our application. Our app is simple and we don't want to use a state management library. All our requirements are satisfied with using one root useReducer(). The problem we are facing and don't know how to solve is async operations.

In a discussion with Dan Abramov he recommends Solution 3 but points out that things are fresh with hooks and there could be better ways of handling the problem.

Loading variables from .env files in Ansible

Ansible has various ways of looking up data from outside sources, including plain text password files, CSV files and INI files. But it doesn't seem to have a lookup for .env files, as used in Laravel projects, also available for PHP, Ruby, Node.js, Python and others.

One option is to launch Ansible with the Ruby dotenv command line script... But that requires Ruby, which seems like overkill to me.

So here is a simpler solution that I use. It consists of:

1. The .env file itself
2. A small shell script that loads the .env file into environment variables - ansible-playbook.sh

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule
