JAX San Jose

Get the Scoop on Git at JAX USA

In version control, Git is certainly the very best available today.

The JAX conference series will come to San Jose
later this year. Speakers and sessions
are already being confirmed over at the JAX website, including two
sessions from co-founder of Ambient Ideas, Matthew McCullough.
McCullough will present a hands-on ‘Git Going with a Distributed
Version Control System!’ tutorial, and a session that will
encourage attendees to get on board with Git, ‘Git in a Nutshell.’
JAXenter spoke to Matthew McCullough, to find out more about the
advantages of using Git, and the sessions he will run as part of
the JAX conference.

JAXenter: In Germany, Subversion is the most
widely-used version control system, but Git seems to be gaining
more and more ground. Is this something you have experienced,

Matthew McCullough: It most definitely is
something that I’ve seen in my consulting practice as well. And you
know what, I respect Git’s historical predecessor, Subversion. It
brought many improvements to the table. But we have a
responsibility as software craftsmen and craftswomen to use the
very best tools. We want to be at the top of our practice and known
for excellence. Git is a tool that enables developers to be more
precise and agile in their work. Past version control systems have
tended to be more of a “backup my code” type of tool. The idiomatic
attitude around Git is that it tracks your thought process around
changing code and lets you navigate through that thought process
and treat it more like a mind map (organic) than a train track

JAXenter: What makes Git such a good
alternative to other tools?

Matthew: First off, it passes the first litmus
test of being open source, well accepted by cautious organizations,
and high-performance. It follows that up with the additions of no
requirement of network connectivity, very little footprint on disk
(no registry entries), simple setup (plaintext files), and a great
set of GUIs and IDE integration on Linux, Windows, and Mac.
Speaking to the human side of the tool, it is very adaptable. Let’s
say that you make a mistake on a commit message. No problem. Just
git commit –amend it. Let’s say you want to try a merge again. No
problem. Just ‘git merge –abort’ the in-progress merge and retry
it later. Lastly, let’s say you get interrupted in the middle of
working on some modifications and are requested to get back to a
clean state and test some code. No problem. Just ‘git stash’ and
the work in progress is safely saved for later and your directories
are restored to the last committed state in just a matter of a
second or so. There are dozens of examples where the Git tool helps
you without being judgemental of how you got into a situation.

JAXenter: You are hosting a full day tutorial
on Git at JAX San Jose. Who should attend this tutorial, and what
can they expect?

Matthew: Students that have knowledge of any
previous version control system are welcome and will learn Git in a
very vertical fashion. By that, I mean, they’ll learn not only the
command line keystrokes, but what is happening one level deeper.
This is a great architectural exercise. A frequent JAX speaker,
Neal Ford, lauds Git as being an example of fantastic tool design.
It is lightweight, liberating, and yet capable and scalable. I’m
also seeing a trend towards distributed version control systems
(DVCSs) in many hiring organizations and I think having DVCS skills
will be a great complement and tie-breaker when seeking new
employment. Employers are ever-increasingly looking for engineers
that keep abreast of the best-of-breed tools. In version control,
Git is certainly the very best available today.
