Following the Tweets from DEVOXX

Posted by editor on November 17, 2009 at 5:25 AM PST

As you can see in Java Today, the Java Tools Community is providing Devoxx live coverage! via http://twitter.com/javatools. Twitter coverage of conferences seems to be overtaking blogging, at least for as-it-happens coverage. If you go to the DEVOXX 2009 home page, you see "#Devoxx Tweets" prominently occupying the left column of the page. Meanwhile, a search for Devoxx posts at Technorati or Google Blog Search as I write this post (about 6:00 AM GMT Tuesday), yields only a few blog entries.

This is amazing to me! Or, at least, I would never expected reporting on conferences to come to this point, where a "story" consists of a set of <= 140 character "tweets" -- and the number of blogs you can readily find after Day 1 of a major conference is a handful -- and the conference itself highlights an agglomeration of the tweets.

As I said when I followed TheServerSide Symposium via Twitter, a conglomerated Twitter feed does give you the feeling of being at a conference in the hallways or some crowded central area, where you hear many different people saying many different things, but all centered on what's going on at the conference. A conglomerated Twitter feed is unique in that way.

Of course, if you actually want to learn something, for example, about what was stated at a specific conference session, you need to step out of the crowd and go into a specific tweeter's set of tweets. For example, the Java Tools tweeter(s) attended a presentation on Generics on Devoxx Day one. The Java Tools tweets tell us that Professor Eric Steegmans explained the basics of generics:

Pros: better readability, compile time verification

Type erasure: the compiler removes all informaion on generic types for binary compatibility with legacy code

At compile time the code is converted to raw types. So Java 1.6 ArrayList is still compatible with 1.4 ArrayList.

And so on. As you can see, you can actually learn something about what was said in the presentation.

So, today, we publish in real time the notes we previously scribbled into notebooks as we attended conference sessions (at least, that's how I always did it). We publish those notes live, as the events are occuring -- rather than recording a day or half-day of notes, meditating briefly upon them, so as to gather some sense of the overriding import, then posting a blog based on the notes and the subsequent analysis.

After the conference is over, the presenters publish their presentations. And there are videos of the keynote addresses. And some people do post blogs, though more after the fact (for example, post-conference summaries) than was the case in that by-gone pre-Twitter era...

Ultimately, I suppose this new method does provide pretty decent coverage of the happenings from a conference. We're provided with a lot of raw material from the conference, that we can interpret ourselves in whatever way we choose. At the same time, I do consider the reduction of insightful blogging, that includes a few moments of reflection upon the import of the events, to be a loss for those who were unable to attend the conference. Tweeting really can't be journalism; blogging can be.

Anyway, this week I'll be following Devoxx via tweets from @JavaTools and Geertjan Wielenga, and I'll undoubtedly find some other interesting people to follow as well, from browsing the devoxx Twitter search feed. It may not be journalism, but from the right sources, tweeting is great reporting.

The next time I attend a technology conference, I intend to blog during breaks, and especially in my hotel room each night -- just as I've always done. But, yes, I'll be tweeting throughout the day, too!


In Java Today, James Gosling is enjoying Moules Frites @ Devoxx:

I'm back in lovely Antwerp for Devoxx. The purgatory we're in over the situation with Oracle has it's pluses and minuses. On the plus side, I don't have to do a keynote.... Steve Harris from Oracle get's that job. I will be doing a talk, but I'll be concentrating on the store we're in the process of launching. The hard part is that the only questions that anyone will be asking are the ones that neither Steve nor I can answer: until the acquisition clears the EC competition commission and closes, we're required to be mostly silent about the future. We're pretty much limited to the official statements...

Geertjan Wielenga interviews Tim Boudreau in his new article NASA Adopts the NetBeans Platform:

Tim Boudreau, Senior Staff Engineer at Sun Microsystems, recently spent some time with engineers at NASA, showing them how to use the NetBeans Platfom. Below, he reflects on some of the interesting engineering needs that NASA has and how the NetBeans Platform is well suited to respond to these. During the interview, Tom Wheeler, one of the NetBeans Platform's several external contributors, talks about his participation in the course at NASA, too! ...
