Blogging Roller

We haven't released the standalone Roller-Planet application yet, but the .Sun Engineering team quietly deployed the latest bits at planet.sun.com a couple of weeks ago in response to requests from the Glassfish, SWDP and other teams for planet-style web sites. You can follow the links on the main page to find planets for Glassfish, SWDP, Sun India, Sun Alumni, Sun Java System Web Server, web services and globalization bloggers.

What's Roller-Planet? It's a community aggregation server, similar to Planet-Planet but with some key differences: it's got a web UI that enables groups of users to run their own planet sites, it's based on Java and it uses the ROME feed parser and fetcher. I've written about it before. We don't have a release plan yet for Roller-Planet so if you really want to try it you'll have to fetch and build it from the Apache Roller SVN repo.

I've really been enjoying Geertjan's blog recently. Lots of interesting details, screenshots and his passion for his work really comes through. His posts on the Netbeans Schliemann generic languages framework and today's Capturing Matisse make me want to drop everything and start hacking Netbeans. And I'm especially happy to see that somebody is interesting in Breathing Life Back into a Dead Coyote (part 1 and part 2), which is currently the main vehicle for Groovy language support in Netbeans -- I'd hate to see Groovy dropped in the mad rush to Ruby.

Last week was deadline week for JavaOne and ApacheCon EU presentations, so I was busy. Fortunately for me, my other deadlines were postponed, I did some begging for time and I actually had time to take a short vacation; a family reunion at Stone Mountain park, Georgia. Here's some more information about my ApacheCon talk and an outline of the slides. 

We've decided to change the time and place of our Raleigh Bloggers meet-up. Too many folks complained about Tuesday night, so we've moved to the 2nd and 4th Wednesdays of each month. Now we'll find out if "Tuesday's not good for me" was just an excuse to avoid hanging with the tech/geek patrol. And we've moved from crowded and loud Helios Coffee to the quiet Raleigh Times Bar (yeah, right). I mean, if nobody's gonna show up we might as well drink, no?

When: Second and Fourth Wednesdays of every month at 6:30PM

Where: The Raleigh Times Bar (Map)

I've been slacking off with the blogging this week, but there's some other Johnson blogging going on. Dad's enjoying his Photophys blog and getting good feedback on the draft chapters of his book. He's posted the first seven chapters now. By the way, my multi-domain hack seems to be working pretty well -- photophys.com is hosted on the same Roller instance as this site rollerweblogger.org.

And brother Dan is keeping the blogging going at Film Babble blog. Check out his Oscar predictions. He's also writing at Helium.com and up to 119 posts there, each a mini movie or music review. 

I've been updating my javax.ws.rest post with links to blogs about JSR 311: Java (TM) API for RESTful Web Services. I went from a couple to nine links today and I'll probably keep on linking, but I'm about to go quiet for couple of days. It's wiki mountain weekend time again.

James Governor: Covalent gets its mojo back and refocuses on its core competence - supporting open source code, and doubles down on Apache projects, going back to its roots. The latest example of Covalent seeing an opportunity and nailing it is the company’s announcement of support for the Roller blog platform. That’s now two companies, IBM and Covalent, making direct revenues from a platform originally built by a Sun employee, but for which Sun has no business model. Here is a hint Sun - perhaps its not software you need to sell but service and support. That is what Covalent is nailing.

I appreciate the support from James and the Redmonk crew. They always seem to be rootin' for Roller.

Of course I'd like to see better support for Roller all around, but at this point I can't say much beyond this: I'm focused on building a great blog platform and support is a very important part of any platform.

A couple of small corrections for James. I was not a Sun employee when I originally developed Roller. Second, IBM hasn't shipped Connections, so they're not any making "direct revenues" yet. Third, I don't know if Covalent has "nailed" anything -- I haven't heard from anybody who has tried the service and I'm still trying to figure out exactly what they offer.

I mentioned before that I convinced my Dad to start a blog. Well, now after a week or so of back-and-forth with Kattare.com getting the domain handling setup properly and modifying Roller to support multiple domains, his blog is live running on the same Roller instance that I use for this blog (but with the domain photophys.com).

Dad's blog is titled Photography: Appreciation through Understanding. He's publishing draft chapters from his new book there, hoping to get feedback and attract some new readers.

Hmm... RSS and Atom feeds don't seem to be working correctly. Apparently, I've still got some multi-domain work to do...

Aaron Cohen is looking for feedback on a simple and clean new Roller theme known as Eco.

Update: Linda says Eco is not really a "Roller theme" as it relies on some .Sun Engineering ad-server components to serve up the rotating eco-fact. She's got some instructions for BSC users interested in the theme on her blog.

Matt Raible has been talking to folks at Sun (including me) about working for Sun. Now he's using his blog as part of the interview process. He asks:

For those folks out there that have worked for Sun - what's it like? Is it a good place to work these days? Would you recommend it for a passionate open source developer like myself that likes to make contractor rates and take lots of vacation?

I've already talked to him and told him what I think. We didn't talk about vacation, which is a disappointing two weeks for a new employee, but other than that I think Sun is a great place to work for a passionate open source developer. If you work at Sun or worked at Sun, leave a comment on Matt's blog or send him an email and tell him about your Sun experience. 

Pixyblog is a photoblogging site, powered by Roller. Looks slick.

Update: Raible blogged about Pixyblog too and some Sun-related news about his job search. 

Over the weekend I convinced my Dad to start a blog and I offered to host it on my site with Roller (of course). We've already started to set the site up. Dad picked up a nice short domain name, I added it to the kattare.com name servers (Kattare is my ISP) and I added support for the new domains to my Apache/Tomcat setup there.

Now I have to to figure out how to host multiple domains with Roller. That's a topic that has come up before.

A while back LinPro Norway developed a multi-site capability for Roller. I called it multi-domain at the time, but now I think that was wrong. As I understand it, multi-site allows one Roller database to serve multiple Roller sites. Each site having it's own Server Admin settings and serving one or more domains. Mutli-site requires significant changes because the each table must have an additional field that indicate which site it belongs to. Unfortunately, the patches were too extensive for us to incorporate into Roller.

What I'm doing now is multi-domain, which appears to be much easier. I'm not sure multi-site and multi-domain are accepted terminology, so I'll explain. I want one Roller database to serve multiple domains, but with all domains sharing the same Server Admin settings. It's definitely going to require some code changes, but with the new 3.0 rendering system, I'm finding that those are pretty easy to do. In fact, I've already got some working code ready to deploy. Once I get it deployed and working, I'll write up a proposal and see if I can get simple multi-domain support into the Roller codebase.

Speaking of science writing and making more science accessible to lay people, check out my Dad's article at Luminous Landscape where he explains Why Is My 50mm Lens Equivalent to 80mm on a 35mm Camera and Why Is There More Depth-of-Field? And check out the comment he received:

Nathan Myhrvold: I think that Charles Johnson’s article on DOF and sensor issues is excellent and will inform the discussion of the relative merits of various sensors and cameras. It covers the basic optical facts very well. However, I think that there are some additional points that can help clarify the issue...

Yes, that Nathan Myhrvold. Apparently, he shares both Dad's love of nature photography and of physics. Dad was pretty happy to see such detailed and well-informed feedback. See what happens when you post interesting writing on-line? Cool things! and you might make an interesting new friend or two. Get a blog Dad.

When I'm under deadline pressure of any sort, I tend to stop blogging. That's the case this week. It's already Thursday and haven't written about the NC Science Blogging conference that I attended in Chapel Hill last weekend. Gotta fix that.

The NC Science Blogging conference was put together by the BlogTogether crew, the same group of Chapel Hill bloggers that organized PodcasterCon last year and BloggerCon the year before - Bora Zivkovic, Anton Zuiker, Brian Russell and others. Again they put together a wonderful un-conference and drew a crowd from up and down the east coast and beyond.

The days started with a Science Blogging 101 session by Bora himself. Next up was Hunt Willard, director of the Duke's Genome Sciences & Policy institute. He's not a blogger but he had good advice for science bloggers and stressed the importance of science writing, engaging the public and making science more accessible to lay people. Brian Russell posted audio of Hunt's entire talk. Popular science blogger Janet Stemwedel was up next. She talked about her personal experiences as a science blogger and also stressed the importance of engaging the public and making science more accessible. Here are her slides (PPT).

In the afternoon, I went to a session on blog illustration, which focused mostly on copyright issues. I was a little surprised to hear no mention of SVG and MathML. The last session I attended was devoted to helping the Museum of Life and Science (Durham, NC) figure out how to use blogs to engage and educate the public about nano-technologies (they've got an NSF grant to do things like that).

After the talks wrapped up a big crowd headed over to Carolina Brewery and Penang for dinner and I got a chance to hang out with the Chapel Hill blog mafia. That's something I always enjoy, plus I got to meet congressman Brad Miller again. All and all a great day. Thanks to the BlogTogether folks for putting it all together.

Update: I forgot to mention the blogs. If you'd like to read more about the conference, there's a big list of blogs and news stories about the Science Blogging conference on the BlogTogether site.

Alexis Moussine-Pouchkine has taken my Generating JSON for your Roller blog post a few steps further down the road. He created a screen-cast to show how easy it is to use Netbeans 5.5 and the JMaki widget wrappers to serve up Roller data in a a Dojo table. Cool stuff. I really need to find the time to take JMaki for a spin.

And BTW, I'm still working on my Dojo table example, which will be similar to what Alexis has done but it will use Dojo directly within a Roller blog -- no IDEs or JSPs required.

It's time for the first Raleigh Bloggers meetup of the new year.

About Us. We are a group of bloggers who live in and around Raleigh, North Carolina. We meet twice a month at a local coffee shop just to chat. We have no formal agenda. Sometimes we talk about blogging, sometimes podcasting, sometimes technology, sometimes politics, ... mostly whatever's on our minds. We've been meeting regularly since March of 2005.

Join Us! New faces are always welcome, whether you're a professional blogger, a newbie looking for help starting a blog, or someone who just likes to talk about nerdy things. All you have to do is show up and look for a group of guys with laptops (invariably it's always guys, but women are certainly welcome!).

Meetup details are on the wiki.
