Git Introduction

Video: http://youtu.be/W4RxNIc5eJI

My first talk/lecture! This is a lecture I volunteered to give to my class in the second year of my degree. I gave it on the 3rd of Feb, 2015 to around 60 students studying either Computer Science, Software Engineering, or Game Development.

You can see my presenter notes on the markdown file in this release on GitHub: https://github.com/kylejm/Git-Introduction-Lecture/releases/tag/1.0. It's worth looking at the notes as they'll provide more context for each slide.

If for some reason in the far far future the link above stops working (probably because I've moved the repo and forgot to update the link), please poke me and I'll fix it 😄.

You could also download the whole repository and open it in DeckSet: http://decksetapp.com.

25. REPOSITORY (REPO) A place where things are stored and can be found — The Cambridge Dictionary
26. SUBVERSION (SVN) 2000 • OPEN SOURCE NON-TEXT FILES • DIRECTORY SNAPSHOTTING
27. BITKEEPER 2000 • CLOSED SOURCE • FREE COMMUNITY VERSION DISTRIBUTED VCS
28. SCCS - 1970, closed source, smarter storage RCS - 1982, open source, even smarter storage, multiple OS CVS - 1986, open source, multiple files, repository SVN - 2000, open source, dir snapshotting, non-text files BitKeeper - 2000, closed source, Distributed VCS
30. GIT DEV STARTED APRIL, 2005 ▸ Distributed VCS ▸ Multiple file types ▸ Super fast and reliable ▸ Open source ▸ Compatible with Unix like OS (Linux, Mac OS X, Solaris) and Windows
31. GITHUB Launched 2008 By 2009 had 50,000 repos and 100,000 users
32. GITHUB Launched 2008 By 2009 had 50,000 repos and 100,000 users BY 2011 HAD OVER 2 MILLION REPOS AND 1 MILLION USERS
33. DISTRIBUTED VERSION CONTROL
38. DISCRETE CHANGE SETS, NOT DELTAS (DIFFERENCES) Repo 1: A, B, C, D, E, F, G
39. DISCRETE CHANGE SETS, NOT DELTAS (DIFFERENCES) Repo 1: A, B, C, D, E, F, G Repo 2: A, B, C, E, G
40. DISCRETE CHANGE SETS, NOT DELTAS (DIFFERENCES) Repo 1: A, B, C, D, E, F, G Repo 2: A, B, C, E, G Repo 3: A, C, G Repo 4: B, D, E, F, G
41. BENEFITS OF DVCS ▸ Faster ▸ No network access required ▸ No single failure point ▸ Devs can work independently IT ALSO ENCOURAGES PEOPLE TO FORK OPEN SOURCE PROJECT
43. STORY OF A Dev Team
