Q & A

• Open source contributions and meetup reflections both due by the 29th
• From now on: snapshots of your work
• Pycharmers: snapshot into trinket or use git (instructions will vary slightly from below)

Project Update 1

• Pair up
• Merge up
• Stand up (not literally)

During standup:

• What did you say you’d do?
• What did you actually do?
• Show and tell your program
• What will you do for next class?
• Any problems?

After everyone’s done their update, revise your milestones (in your existing post) and get your partner to merge your revisions.

Basics for Cloud 9ers (and anyone else interested) - Last ~15 mins of class

Write and run a Python program:

• make a .py python program
• in a terminal, type python3 [filename]
• OR add the magical #!/usr/bin/python3 to the top. You can then use C9’s Run button.

Initial git setup:

• cd into your project directory (put your stuff into a directory if needed)
• git init if you haven’t already
• git add .
• git commit -m "your commit message here"
• Make a repo on github.com. Don’t initialize it with a Readme!
• git remote add [name] [url]
• git push -u [name] [master]

Each time thereafter:

• save your work
• Add, commit, and push. The other steps are only needed once. When you git add you can specify specific filenames instead of all files.
• Verify that your new commits show up on github.com. This is where intelligible commit messages will help.

Notes:

• git status, ls and pwd give you info!
• I’m allowing you to commit to and push to the master branch for simplicity. You’d only do this for a personal project and even then branching is always a good idea. Know on a real project you’d be doing pull requests!
• Try to commit locally each time you hit a milestone. That’ll make your commit history mirror your progress. If you wait till the end your commit history won’t be very useful.
• Remember to push your changes before every project update!

Customization:

$HISTSIZE and other Bash environment variables. c9 ~/.bashrc is where you’d edit this. Here’s what I added, at the bottom:

export HISTSIZE=100000 # big big history
export HISTFILESIZE=100000 # big big history

Anything you put into ~/.bashrc will be run every time you open a terminal. It’s a handy place to customize your environment. Note the ~. In C9 you start in /workspace or etc and .bashrc is in the root of your user’s home directory, aka ~.
