Git vs SVN comparison

Summmary

Overall SVN easier to get into and is more accessible due to the
excellent app called TortoiseSVN (TSVN).
It is a GUI tool that allows you easy execution of all important
standard workflow commands via good explorer integration.

Git has a not yet such excellent tools.
However TortoiseGit (TGit) is in heavy and rapid development.
Git GUI, part of the standard windows git package, and especially
the all-in-one package gitExtensions are work well.

For experienced devs, check WhyGitIsBetterThanX for an advanced
high level, brief and still extensive summary and comparison.

  • GitCasts: Git on Windows. 13 minute screencast.
    Nice straight forward introduction to git; installing git on windows,
    using git GUI. Needs basic understanding of VCS.
  • Distributed Version Control with Git 50 minutes screencast.
    Explains VBS in general, pros of distributed ones and
  • Git Overview Demo 30 minutes screencast. Quite nice video
    explaining in detail and easy to understand how to do
    the basic operations on command line. Great way to get
    into the basic workflow and possibilities of VCS.
    Also show git GUI briefly.
  • git-gui screencast 6 minute screencast.
    Explains basic workflow of git GUI and shows how to
    stage and commit single line(s).
    This allows small, atomic commits easily! No longer worry
    about changing several aspects at the same time.
    You can sort the commits later on smoothly with this.
  • GitExtension videos tutorials:
  • Hasan on GIT: 20 minutes recording of git presentation.
    Fair job and bit more interactive and fun due the present audience.
  • RailsConf Git Talk. 55 minutes screencast.
    By schacon - extremely well done and very extensive!

Advanced:

These are all command line based videos explaining the basics of git throughly.

  • GitCasts: Normal Workflow: 5 minute screencast.
    This episode demonstrates how to setup your .gitignore file, how to use and
    interpret git status output, how to add and remove files from your index,
    how to commit and what git does in the object database during these operations.
  • GitCasts: Setup, Initialization and Cloning: 5 minute screencast.
    This episode shows you how to setup your Git configuration, how to initialize
    a new repository and how to clone an existing repository over both
    the Git transport and the HTTP transport.
  • GitCasts: Git Diff: 9 minute screencast.
    This episode goes over some of the common or interesting options to 'git diff',
    showing how to see what has changed between your last commit and
    your staged files, unstaged files, all changed files or another commit.
    We also demonstrate how to create and apply patchfiles and
    how to view changed file stats using diff.
  • GitCasts: Git Log: 6 minute screencast.
    This episode is on git-log, which demonstrates most of the major features and
    options to the git-log command. It includes showing the stat, short-stat and
    name-stat options, the pretty options, the since and until limiters, the path
    limiter and author field searching.
  • GitCasts: Interactive Adding: 4 minute screencast.
    This episode demonstrates how to use the git interactive add command.
    It covers all of the major features of interactive adding, including status,
    update, revert, add untracked, patch and diff.

Expert:

  • GitCasts: Branching and Merging: 9 minute screencast.
    In this screencast, we take you through a workflow where we branch, stash and
    merge several times. It demonstrates the branch and show-branch commands,
    how to switch branches, how to stash changes, how to list and apply stashes,
    how to resolve conflicts, how to create and delete topic branches,
    and what fast-forward merges are.
  • GitCasts: Rebasing: 10 minutes Screencast.
    This screencast follows roughly the same course as the previous one on
    branching and merging, only I replace merging with rebasing.
    This screencast also demonstrates the interactive rebase command git rebase -i.
    I also demonstrate some slightly more complex branching, by using both
    interactive and normal rebasing techniques simultaneously on separate branches,
    then choosing one and deleting the other.
  • GitCasts: Git Submodules: 15 minutes Screencast.
    Needs submodules concept understanding!
    Shows use of submodules quite extensively and well presented.
  • GitCasts: Browsing Git Objects: 7 minute screencast.
    In this episode, I show how to browse and inspect raw Git objects.
    The major tools covered are the git cat-file and git ls-tree commands to
    inspect the object contents, and then I cover some of the included graphical
    browsers, gitk and gitweb.
  • GitCasts: Distributed Workflow: 14 minutes screencast.
    This screencast demonstrates a distributed workflow. It takes two personas,
    creating a project in GitHub and pushing to it in the first persona, then
    cloning that project in the second. The second sets up a public, read-only
    HTTP repository on his own server. The first then fetches from that, merges
    changes and pushes back to GitHub. It also demonstrates an instance in which
    the Author and Committer fields can differ for a commit.

Further reading

  • Git-presentations by schacon
    • Basic git talk: 60 minutes screencast version.
      High level overview of Git, why people use it, comparisons to SVN (including benchmarks), then a rundown on basic usage
      - setting up, workflow (edit/add/commit), what's happening behind the scenes, branchingand merging, log, diff, etc.
      About 1 hour if you talk as fast as I do and there aren't any questions, but it's taken me close to 2 hours before with
      a chatty audience.
    • Git world economy talk:
      This is a short, 30 minute or so talk that I tend to give at larger companies that is very high level and fast paced,
      intended to convince people to move their personal and company open source projects to Git and GitHub. This talk is
      about half high level Git evangelization, then half GitHub evangelization.
    • RailsConf08:
      The first big talk I gave on Git in early 2008. There are over 500 slides here, but I gave them fairly easily in about
      45-50 minutes. I did a screencast of this deck, so you can see the presentation being given (url in the readme in that
      subdir). It introduces basic Git concepts, starting from the internals, then goes over all the porcelain you use most
      often. This is a bit old (pre 1.6), it still assumes you have all the executables in your path rather than in libexec,
      and I've since moved away from talking about internals off the bat (Basic Git Talk still goes over some internal
      concepts, but much more gently and farther into the presentation, I think.
    • Sor09:
      This is the talk I gave at Scotland on Rails in 2009. It has a lot of the Basic Git Talk, plus a number of advanced
      commands (revision selection, bisect, rebasing, etc). It is a large deck, over 500 slides - it will take at least 2
      hours to get through. I did 80% of it in 45 minutes, but I was in overdrive., One could easily split it into two
      shorter presentations.

Handy extension

  • Git Remote Branching: git remote branch is a simple command-line tool
    that makes it very easy to manipulate branches published in shared repositories. Very useful script written in Ruby.
    Can be used to simplify managing remote branches (create, track or remove)
  • Experimental Client - NetBeans Git Plugin: This is only a wrapper,
    you still require a git implementation (MSYS/CygWin).
