Leftover questions

Why can’t I get Java to work on my laptop?

That’s a great question. Did you try downloading the “complete VSCode package” from https://code.visualstudio.com/docs/java/java-tutorial?

You can always work in MathLAN. There are people here to share your suffering.

I’m confused about Git.

I hope that today’s lab will help. If not, let’s chat.

What’s the difference between Git and GitHub?

Git is collaborative version control software. You can use it to store versions of your software in various locations, including your local disk.

GitHub is one of the more popular hosting services for Git repositories. (GitHub also provides software that you can use to create your own hosting service.)

Java is weird.

It will feel less weird the more you get used to it. Ask questions! Accept that some things will be weird.

VSCode lab

All new for this semester! Apologies for bugs.

• Bug one: You need to install the “Extensions Pack for Java” before beginning.
• Bug two: Misformatting.
• Issue one: It’s a Microsoft Product. Things will go wrong in confusing ways.

Git lab

Revised for this semester! Apologies for bugs.

• Bug one: https authentication is disallowed.
  • Create an ssh keypair: https://mathlan.sites.grinnell.edu/ssh/fastx/2019/07/22/Public-Private-Key-Pair/
  • Follow the instructions at: https://docs.github.com/en/authentication/connecting-to-github-with-ssh/adding-a-new-ssh-key-to-your-github-account
