It’s all about the workflow

In the last few months I’ve been running into the same issue over and over again. At OSCON I was out to dinner with some Apache/Subversion friends. In recent years, conversations with these friends turn to the subject of Subversion versus one of the distributed version control systems, usually, but not always git. And as often happens, the conversation was focused on particular features of the systems. Distribution, obscurity of command sets, the workings of various individual features. For me, the important thing about the DVCS’s is not the various features, it is about supporting a particular kind of development model, a workflow of using the tools.   Vincent Driessen’s excellent post on the git branching model, outlines the kind of scenario that I want to be able to support. That workflow is important to me, not the particulars of git. I’d be happy if more than one tool could provide good support for such a workflow. To my relief, that’s what at least some of the Subversion committers want to be able to do, and I’m looking forward to seeing their work. On the git side of the house, Vincent has written git flow, some extensions to git that make the workflow easier to manage when using git. Github’s recently enhanced pull request mechanism is another example of great git related workflow management.

Software that focuses on workflows is much more valuable to me (assuming it supports a workflow that I use – not a foregone conclusion). Each piece of software that I use on a regular basis has been selected because it supports a workflow that works for me, or because I can mould it into supporting a workflow that is comfortable for me. So today, that means NetNewsWire for Mac’s combined view and OmniFocus on Mac/iPad/iPhone for review mode on the desktop and iPad, and forecast view on the iPad. I also have use Python to make some Macintosh desktop apps provide a workflow that ‘s more suitable for me: For mail, that means plus Mail-Act-On plus Python scripts plus Keyboard Maestro. For meeting notes that means Evernote plus Entourage plus Python scripts on the Desktop and iPad

One domain where I still haven’t found a great fit yet is the activity/life stream space. Right now I’m using Echofon on the Mac, Twitter for iPad, and Twitter for iPhone. I also have Flipboard on the iPad. Each of them works relatively well, but none of them really solve the problems that I have as a high volume Twitter reader. I really haven’t seen anything that works in a way that will really help me deal with the firehose of information from various online sources of various kinds. Here lies an opportunity.

App developers of all kinds, giving me neat features is good. Streamlining my workflow is better.

CouchCamp 2010

I spent a few days last week at CouchCamp, the first mass in-person gathering of the community around CouchDB. There were around 80 people from all over the world, which is pretty good turnout. The conference was largely in unconference format although there were some invited speakers, including myself.

I think it says a lot about the CouchDB community that they invited both Josh Berkus and Selena Deckelmann from Postgres to be speakers. The “NoSQL” space has become quite combative recently, so it is great to see that the CouchDB has connections to the Postgres community, and respect for the history and lessons that the Postgres folks have learned over the year. Josh’s talk on not reinventing the wheel was well received, and his discussion of Joins vs Mapreduce took me back to my days as a graduate student in databases. His talk made a great lead in for Selena’s talk on the nitty gritty details of MultiVersion Concurrency Control

There were lots of good discussions on issues related to security and CouchApps, but the discussion that got my attention the most was Max Ogden’s discussion on the work that he is doing to open up access to government data, particularly around the use of location information. He’s been using GeoCouch as the platform for this work. In the past I’ve written about the importance of a good platform for location apps, particularly in the context of GeoDjango. GeoCouch looks to be a very nice platform for location based applications. This is a very nice plus for the CouchDB community.

These days, it’s impossible to be at a conference that involves Javascript and not hear some buzz about Node.js. As expected, there was quite a bit of it, but it was interesting to talk to people about what they are doing with Node. Everything that I heard reinforces my gut feel that Node.js is going to be important.

I was one of the mentors for the CouchDB project when it came to the Apache Software Foundation, and I was asked to speak about community. The CouchDB community has accomplished a lot in the last few years, and is doing really well. I prepared a slide deck, but didn’t project it because my talk was the last talk of the conference, and we wanted to do it in the outside amphitheater. I also wanted to tune some of the sections of the talk to include things that I observed or was asked about during the conference. The biggest reason that I prepared slides was to show excerpts of Noah Slater’s CouchDB 1.0 retrospective e-mail. A lot of what I think about community is summarized well in Noah’s message, and the note summarizes the state of the community better than I could have done it myself. I hope that we’ll be hearing more testimonials like Noah’s in the years to come.
