Best Training Ever: Internal Drupal Hackathon at Goodwin College

I just wrapped up a week-long training with my development team today and this was the best training ever: we eschewed the traditional bring-in-the-expert-to-drone-over-some-powerpoint model and styled our week-long training as a hackathon instead.

There were six developers from my team and two from another department all looking to learn how to use Drupal for different projects. These are real projects with real (internal) customers and we all thought that Drupal might be the right tool for the job, but none of us knew how to use it very well. Some of us had played around with it, but some of us hadn't. For one person it was their first time working with a cms. For me it was my second time getting my hands on a drupal instance.

We didn't know how to develop for it as a platform and we didn't know how to install and configure it so that it would be a reliable and secure content management system for our customers. We didn't know how we would set up our dev, test and production workflows, and we just plain didn't know where to begin wading through the sea of modules to find the right tools for our specific needs. Our boss hired an outside consultant to join us for the week to either teach us or work along side us for the week, whatever we needed. We really lucked out getting Tim Plunkett from Zivtech--this guy is an active contributor to many of the Drupal modules that we ended up needing. He knows his stuff and he was excellent at not only teaching us what we needed to know but also teaching us how to find answers when it comes to Drupal and its many modules.

Why was it so awesome?


I have never, ever, learned so much in such a short period of time. It was so efficient. I felt like I was in flow most of the time. I felt that rare electric feeling like the whole room was in flow, like we have never been as a group.

Learn by doing--it's how I learn best; it's how a lot of us learn best. Even better was that because we were all learning different things at different times I had opportunities not only to learn but to teach what I just learned to someone else. This cemented my learning, in a matter of hours, not weeks. On that note, I am sure, SURE, that what I accomplished on the second day would have taken me at least two weeks on my own. That feels amazing.

Here's how it worked


For the most part it was one (or more) project per person, but I was actually on a team with one other developer because our project has a deadline of April 16th (just over a week after the hackathon--ambitious!).

Here were some of our projects:
  • Porting of some static html to CMS with theming (this was mine--with the short deadline), laying groundwork for future massive site migration in to CMS
  • Porting a wiki-based site to Drupal to take advantage of better add-on functionality
  • Q&A site for teachers (replacing existing software)
  • Faceted search/browse prototype for a customer with a ton of diverse but related content
  • Hardware inventory/maintenance history logging system for sysadmins
  • Massive open online course platform
  • Site for alum-teachers to share videos and other resources with each other

Ahead of time

Ahead of time we set up a wiki page to keep track of the projects and all of the Drupal questions we had going in to the week. I set up a rough agenda that basically said on the first day we each talk about what we are going to do during the week, then each day we work and stop in the middle to check in (or show and tell) and then on the last day we have final presentations. That's it. I wanted to keep it simple and informal so that we could get as much done as possible. We got some budget to buy snacks and pizza for the week and I found us a room that we could use each day for a whole week (surprisingly difficult!). My colleagues and I agreed that it was important that we get away from our desks if we were going to be able to really focus on learning and getting deep in to Drupal quickly.

The week before I sketched out a layout for the room, a rectangle of tables, with enough room so that the consultant or other people could hop in between people. We sent out invites to our internal customers, asking them to stop by for a check in or to give us some feedback. The Friday before my colleagues helped to set up the room, with my colleague Amir making sure that we had things like an ethernet switch, lots of ethernet cables and power strips and even laptop locks. We checked on things like spare monitors, mice and keyboards, which were conveniently around the corner in the main IT office if we wanted to borrow them.

We checked in with Tim, our consultant, to pick up some best practices for getting our dev environments ready. He suggested things like setting up a space in source control for each project and having php, drupal and drush installed and in the right versions.

The hackathon week began

Once we were all there and we got past the initial introductions and started working it was like magic. I was never stuck, wrestling with a bug or a mystery. Either Tim had the answer, or could find the answer or one of my colleagues had it. When enough of us wanted to see something Tim would do a demo for the group and then we would get back to work. People would bounce around the room from time to time, sharing things they had learned and asking questions. We worked like crazy all day and I never had that feeling in the afternoon like I needed a nap--I was actually energized at the end of the day. (I am exhausted now, but it's a great exhaustion, like after an amazing long run.)

We did check-ins each afternoon, except Wednesday we did a mid-week show and tell just to share what we had learned and accomplished so far. This helped us identify people who had already done the things we needed to figure out how to do. I wrote the first module on Tuesday. Well, it was mostly Tim telling me exactly the words to type and what files to create, but it was a very effective tutorial on module building and a first glimpse for me in to some of the APIs and how Drupal works. On Thursday I learned features and had packaged up my work from the first half of the week in to a feature that could be checked in and pushed out to the other development instances.

About mid-week we realized that a lot of our projects were for different parts the same internal customer's (massive) website and so they should actually live in one big Drupal instance. That required a new project, which was the multi-project multi-developer infrastructure and workflow project. Prior to that we had all been playing in our own sandboxes. By the end of the week we had a solution figured out and the development layer set up so that we could develop features and push them out to each other and keep our development instances in sync. Amir even had a prototype of a staging instance and a workflow for deploying up from development with a plan for how that would work for production too.

In the end we covered just about everything that we had hoped to cover and in a lot more depth than I had imagined possible. We made real progress on real projects and we know a lot of how to do what we have left. Plus, we have learned how to figure out the rest.

So what's next?

At the very end of the event I led the team in a retrospective and almost everyone mentioned that we should do this again. There are a few things that we might do differently, like nail down or narrow down our goals to get even deeper and further along on fewer things or set up a better way to organize common questions and answers that have come up so that we can more efficiently share the knowledge we have gained between us. On the whole everyone loved it and we hope we get to do this again and again and again.

My question is why can't every week be like this at work? Is your work like this?

Pair Exchange Program

I just finished the first ever pair programming exchange program!



It all started when I was at SDTConf back in October. I don't remember the exact conversation, but the question was generally if software development as a craft takes two programmers pairing together to pass on and practice the craft then how will it ever scale?



Someone jokingly suggested that Corey Haines should get a bigger car--Corey travels all over the place pairing with people and promoting the craft of software development. One idea that I think Corey actually proposed was the idea of a pair exchange.



The idea is simple: we can't all get Corey Haines or another big name in the XP, Agile, Craftsman, etc. communities to come and pair with us, but there are lots of smart people in every town. If you two are both passionate about practicing and improving your skills then why not use each other as a resource? Everyone has a vacation day to spare, take a day and go pair. If your boss will let you, bring your pair partner to work.



I know a lot of developers in Philadelphia and I had no trouble thinking of the perfect programmer to pilot my pair exchange program with. Woody Zenfell III is not only one of the smartest and most professional programmers I have ever worked with, but we make a killer pair. It is like our brains are wired almost exactly oppositely, but we get along really well. I like that he is fun to work with and we get a lot of good work done together. Plus, I know his company already and I know that he is on a team of 1 and is probably missing working with other developers.



When I first brought this idea up to my manager I had reason to be optimistic. My manager sees the value of pairing, even though my team doesn't really practice it much, and he is very supportive of learning and professional growth. I was thrilled when he agreed to the whole thing, both me going to Woody's office for a day and for Woody to come and pair with me and chat with my team. Woody's boss was also game and we were set!



We decided to do one day at each office, back to back. Since this was our first pair exchange we didn't really know what to expect other than that we would show up, work on some stuff and see what value we get out of it. For me, I knew Woody's code base pretty well, having actually worked on it with him back in our consultant days. For Woody, my team culture and our domain and the code base were all new, so a chunk of time in the morning went to talking about those things. Other than that we just paired; it was awesome. At Woody's place we had some tasks that needed to get done and so we did them. At my place we talked about design for a long time and wrote a test that I was having a hard time writing. Lots of great side-conversations happened with my teammate neighbors. It was fun and we got a lot done.



What did we get out of it?



For this first exchange it seemed like we were for the most part exchanging little tips, tricks and techniques that make us more efficient and effective. Woody, for example, showed me how he is creating dependency graphs (actual pictures) for all of the stored procedures and reports in his system, automatically, so that he can more confidently make changes to them. He is also getting those database elements into source control and refining a test and deployment process for them, which is something I hadn't thought of before, but is really smart given how important those reports are to his company. He also showed me captures in EasyMock, which were exactly what I was always dreaming of but never had because we were still using EasyMock 2.3. In return I showed him ctrl+r in cygwin/linux for searching your history. Then he showed me pushd and popd--that's just so handy.



In addition to tips and tricks we had a lot of conversations about how we do things, like how we work with our users and what process we follow for organizing our work and testing and deployment.



At the end of the second day we took several laps and talked about the experience. We agreed that it was definitely valuable and something we want to do again. We imagined that after a while we will run out of tips and tricks to show each other and then we didn't know what would happen then, but maybe that we could use each other as reinforcements for when something really sticky comes up and we need a fresh perspective. We talked about doing it again quarterly or monthly or more randomly. We aren't sure how our bosses viewed the experiment, and of course they would have to feel like they are getting a good deal out of this for them to allow it to continue. A lot of factors went in to making this experience go smoothly: the fact that we have both paired a lot before and with each other before, that our bosses are agreeable, there are no super-high security requirements that would prevent guests from coming over and peering at the code, etc. I am curious how well it would go if I was pairing with someone I didn't know very well.



I would love to hear about more people who are trying this sort of exchange. If you don't have teammates who pair (or teammates at all) you don't have to miss out on the benefits or pair programming--the discipline and the sharing of new ideas.
