Today I had the pleasure to attend “Git and GitHub Training” held by Tim Berglund one of the GitHubber, so called because he is working at Github.

In the past I enjoyed very much the video Tim and Matthew McCullough, another GitHubber, did for O’Reilly

So it was really nice to meet Tim in one of his course.

What are the class objectives?

  • Understand how Git works and how to apply that to day to day development.
  • Learn how GitHub makes distributed collaboration both effective and enjoyable.
  • Practice the use of Pull Requests to make contributions to any project.
  • Learn the basic 10 commands that will appear in your 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 features of GitHub for easier collaboration with colleagues.
  • Discover how the offline capabilities of Git work.


  • Introductions
  • Git and your initial setup
  • Git configuration and its inheritance
  • SSH Authentication and your first repository
  • Understanding and thinking in Git’s three stages
  • Adding, committing, and diff-ing code changes
  • The Similarity Index; Moving, Renaming, and Removing files
  • Reviewing Version History in Git
  • Strategies for Efficiency (quick workflows, GitIgnores, etc.)
  • Managing and using Git Remotes
  • GitHub
  • Forking Repos
  • Pull Requests
  • Branching, Tagging, and Stashing
  • Merging, Rebasing, and managing conflicts
  • Undoing your work with Git

The course was taking place at Canoo headquarters in Basel, which have really very nice offices and were welcoming us very nicely!

We went through all the topics described and even a bit more as most of the people in the course were already having some experience with git.

Did I liked the course, the format and the way to present it?

Definitely yes! I enjoyed it and would really recommend it to people which are starting with git. I especially liked the way Tim presented the inner working of git which I think is important to get right, especially when you come from another vcs like svn. Also that the log is a graph and not a list…

Did I learned a lot?

Not really but that was planned. I spent almost two years working with git svn at Innoveo Solutions and git for my personal projects. Now I am also using git without the svn part at work and continue to take influence so that the whole company migrate to git. So I gained some experience, which the course would have give me much quicker, and I guess my colleagues, Cédric, Carlos and Christian gained some knowledge in one day which took me much more time to grasp. So the course if a great starter, as for quite some things, you need to practice to really get it!

For people with a good understanding of git I would take care to go to the Advanced Git & GitHub Course.

During the course we had some open discussions on various topics, but here are some which I would like to put some emphasis on.

My personal experience brought me from thinking that I want to have the tools integrated into my IDE to, after getting more knowledge about git, using git from the command line. This makes me as a developer much more efficient and let me automate some stuff, which I couldn’t do with the IDE. For sure I agree with Tim Winking smile that if I would have to work with cmd it would be rude but today there is PowerShell and combined with ConEmu and PoshGit it makes very effective, even on Windows which was still seen as a clicking environment!

I learned about

git config –global credential.helper cache

But this wasn’t working on my Windows machine, so I went back to

This was also new to me

git push –delete origin mybranch

because I am used to do it with the following, which is for sure less expressive of what it does

git push origin :mybranch

Finally things I heard during the course which I want to investigate further are

I also had interesting discussions with some of the Canoo people especially about Scratch, one way to bring kids to programming and the Raspberry Pi.

So that was a great day! And I hope to have some others like this one in the future.
