Editor's Notes

  • #2 we start off a project having a fair idea of what we are going to do ...
  • #3 soon we have multiple iterations, multiple versions...
  • #4 and then we have to collaborate, share...
  • #11 (almost) everything is local... branching, merging etc
  • #12 (almost) everything is local... branching, merging etc
  • #13 initially created by Linus Torvalds, now supported by a huge open source community ... field tested with Linux Kernel
  • #14 You don’t have to go ask someone to create a branch for you, or create a repo for you or request a branch merge.. you do as you please with YOUR copy.
  • #15 We’ll be using the git command line interface, but feel free to choose your preferred solution GUIs, Editor Extension etc
  • #23 Although, I like working in small steps, here are some shortcuts git commit -m “<your msg>” [doesn’t open up the editor for msg] git commit -am “<your msg>” [adds the files tracked and uses msg on command-line]
  • #36 now do a demo of jim workflow
  • #37 now show them a demo of creating ssh key on my ischool account
  • #39 show the students
  • #40 show the students
