It's the beginning of a new year and you know what that means: Public disclosure of measurable goals for the coming year. I've not made a New Year's Resolution post before, which of course means that not living up to them was slightly less embarrassing. Well, this year, I'm going to go on the record with some professional development goals. I consider the purpose of these goals to be exercises of taking myself out of my comfort zone. Simply resolving to do something that is a logical extension of my existing professional development road map is just padding. But before I get into enumerating my resolutions for 2011, let's see how I fared on those undisclosed ones from last year.
How did i do in 2010?
Make git my defacto version control – success
By the end of 2009, I had only used git to the minimum extend required to get code from github. I knew i didn't like svn, because I was a big branch advocate and it just sucked at all related tasks, like managing, merging, re-merging, re-branching branches. I had been using perforce for years and considered it the pinnacle of revision control because of its amazing branch handling and excellent UI tooling. I also got poisoned against git early when I watched Linus assigned the sins of svn to all non-distributed version control system in his googletalk on git. I knew this was irrational and eventually i would need to give git a chance to stand on its merits. But the only way that was going to happen was by going git cold turkey and forcing myself to use it until i was comfortable with it. That happened on January 1st, 2010. I imported all my perforce repos into git and made the switch. I also started using git on top of all projects that were in svn that i couldn't change, keeping my own local branches and syncing/merging back into svn periodically. This latter workflow has been amazingly productive and gives me far greater revision granularity, since i constantly commit WIP to my local branches that wouldn't be fit for a shared SVN trunk.
One other aspect about DVCS that had kept me from it was that I consider version control both my work history and my offsite backup. So, I probably still push a lot more than most git folks. Sure, i've only lost work once due to disk failure vs. several times because of ill-considered disk operations or lack of appropriate rollback points, but I also work on a number of machines and religious pushing and pulling lets me move between machines more easily. Basically, I never leave my desk without committing and pushing because I've been randomized by meetings or other occasions that led me home before making sure i had everything pushed for work from home.
After a year, I can safely say, i'm not looking back. Git has spoiled me and I even use it for keeping track of CM changes for this and other blogs.
The last couple of years I've been doing toy projects in Ruby as an alternative to my daily C# work. But unlike seemingly everyone else, i never found it to be more fun than C#. Maybe it's because i used to be dynamic language guy doing perl and I became a static typing guy by choice. As dynamic languages go, Ruby doesn't really buy me anything over perl, which I'd worked with off and on for the last 15 years. And while the energy of the Ruby community is amazing, too much of that energy seems to be devoted to re-discovering patterns and considering them revolutionary inventions.
Lessons learned from my resolutions
It wasn't as much a new lesson learned as a re-affirmation of an old axiom: Learning something to the extend that you can truly judge its merits and become more than just proficient requires immersion. Casual use just doesn't build up the muscle memory and understanding required to reason in the context of the subject. If you don't immerse yourself, your use of that subject will always be one of translation from your comfort zone into the foreign concept, and like all translations, things are only likely to get lost in the process.
