Coderetreat - the need for preparedness
(crossposted from verdammelt.posterous.com)
This observer has noted a repeated waste of time by attendees of the
Coderetreats he has attended. Herein is described a
simple way to be better prepared when you attend your next Coderetreat
This past weekend was the Global Day of Coderetreat and I attended the
one in Cambridge, Mass. This was my third and I
again saw an annoyance I want to get out of my head.
First, let me recapitulate the idea of the code retreat. The
participants work on the Conway’s Game of Life programming
problem in 45 minute intervals in pairs, throwing away the code after
every iteration. Some iterations have interesting constraints added;
such as ‘no primitives’, ‘no ifs’, or ‘silent paring’.
I have noticed that at each coderetreat I’ve attended some people spend
time (usually only in the first session luckily) fighting with their
environments to get the point where they can start coding. To me any
time spent setting up the environment is wasted time when you have 45
minutes. I’m not saying that this was a /huge/ issue – but a very
little bit of preparation can save plenty of time during the event.
An Initial Attempt for a Personal Solution
Given that I saw (and felt, when pairing with someone who was
unprepared) this problem at the Chicago coderetreat (held the day after
SCNA), I made sure I had a ruby and Java project all set up so
that I had a failing test (
true == false). That way I knew that
everything was all set: all needed libraries, any special configuration
(autotest & rspec always gives me a little bit of
hassle), any other annoying little thing was done. I even went so far
as to push them up to GitHub so others could use them to.
(git makes deleting the code after an iteration very easy:
--hard HEAD && git clean -fqx
It turns out that I didn’t need to do this. There was already a GitHub
repository that did what I needed and much more:
Given that the above repository is set up for 10 programming languages
currently, it is likely that the ones you want to use are already
there. Simply cloning the repository and doing a quick smoke test will
ensure that your environment is ready for the session.
If you don’t find your favorite language – or the skeleton provided
doesn’t work as well as it could – send a pull request (I tweaked the
ruby starting point to let autotest work with rspec right away).
