essential git

2 ways to start a repository:

• start locally:
  • git init - intialize new git repository in the current directory
  • git remote add origin <address-in-github>
  • git push origin HEAD push current branch to a corresponding branch in git
• download from the web (remote repository):
  • git clone <repository address> - locally download existing repository from the web

Where to go for help if teachers aren’t available:

• type your question into the class slack channel.
• remember that internet was created by programmers and there’s lots of resources there for us.
• do a google search.
• check w3schools.com.
• check stack-overflow.com.
• read the python3 docs.
• run help(<function>) (e.g. help(sum)) in colab, a python file or in the python console.
• command click (ctrl-click on windows) in pycharm (links to documentation).
• take a break - usually between 5 minutes and 2 days is best. Sometimes your subconscious mind will help you find the solution you’re looking for - here’s a great presentation about this.

Version Control

The concept of "SOFT"-ware is that it is something which should be easy to change and update (or roll-back).

Before you wrote code you've probably collaborated with other people on word documents or spreasheets.

• Have you ever kept multiple versions of a file, in case you wanted to go back and get things you might have previously deleted or changed?
• Have you ever emailed around versions of a file between several people and struggled to keep everone in sync without overwriting anything, or having changes and contributions get lost?
• Have you ever had trouble with multiple people editing the same files and trying to merge together all their work?

A good free online course:

Like Harvard CS50.

A good note taking app - there's too much to remember

Apple "Notes" is ok, but Joplin is better.
