Git Two Day Workshop

Matthew McCullough will guide you from the basics through advanced usage of Git in two days of lecture, discussion, and many hands-on exercises. Since Git can be quite different than a centralized version control system, Matthew will map the terminology onto Git's more collaborative version control vocabulary and put each new term into practice with demos and comparisons.

Matthew currently is a member of the JCP, reviewer for technology publishers, author of the Presentation Patterns & Anti-Patterns book, multi-year speaker on the No Fluff Just Stuff tour, presenter at dozens of international conferences, author of three of the 10 most popular DZone RefCardz (including Git) and President of the Denver Open Source Users Group.

Git has been a primary tool in Matthew's teaching and consulting practice for several years. Matthew's helped small shops to 5,000 person companies convert from proprietary version control systems over to Git, helping them maximize the benefits and minimize efforts. The resulting productivity and collaboration boosts from development teams have been nothing short of amazing.

Git - 2 days workshop

Git is a technology that is best learned through actual use, and at nearly every step of this class you will be typing commands and evaluating what Git is doing both on the surface and at a deep mechanical level. With the mechanics and day-to-day commands mastered, we will advance to discussing Git-facilitated workflow ideas along with practical time-tested tips that will get you on the road to success with this revolutionary source code control system.

This class will help developers on any platform:

  • Understand how Git works and how to apply that to day to day development.
  • Learn the 10 basic commands that will appear in every-day use of Git.
  • Know how to "back out" mistakes using Git's incredible history and ability to revert almost any change.
  • Leverage the collaboration features of Git for productivity boosts with colleagues.
  • Discover how the offline capabilities of Git work "under the hood" and how to use those to work in more places with less reliance on connectivity.
