What is source control for?

• Backup
• Finding out why
• Multiple simultaneous versions:
  • Releases
  • Individual changes

The centralised model

The distributed model

Centralised Pros

• Simple
• Good UIs
• Linear history
• "Shelf" (Perforce)

Centralised Cons

• Branching is a "big thing"
• Merging can be difficult (SVN)
• Performance can be poor (SVN)

Why git is better

• Distributed
• Share your code with your friends
• Have more than one "central" repo e.g. staging/smoketested
• Have mini-repos for sub-teams
• Work in mini-branches
• git stash is "Shelf" on steroids
• Fast

Why git is better

• Offline
• Fast
• Don't talk to the server until you're ready
• Full feature set when server is down
• Work in mini-branches
• Merging actually works
• Honestly, it is so fast

Don't fear the branch
