Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

Design rules

brew update
brew install redis

To have launchd start redis now and restart at login:

brew services start redis

How to reopen a pull-request after a force-push?

Precodinitions

• You need the rights to reopen pull requests on the repository.
• The pull request hasn't been merged, just closed.

Instructions

1. Write down the current commit hash of your PR-branch git log --oneline -1 <PR-BRANCH>
2. Write down the latest commit hash on github before the PR has been closed.
3. git push -f origin :

  events={[
    {
      childName: "firstBar", // if a child name is not provided, event will be attached to all children. 
      target: "data", // what type of element to attach to. Matches the style namespaces
      eventKey: 1, // What event key of element to attach to. Defaults to the index in data. 
      eventHandlers: {
        onClick: () => {
          return {
            childName: "secondBar", // the child to be modified

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
