Blogging Roller

BarCamp RDU was great fun this year and I'll probably blog a bit more about it later, but for now here's my favorite picture from the event; taken by Fred Stutzman, who led the event in 2007 and 2008. It's my son Alex (11), using Wayne Sutton's cell-phone to stream video of me giving the opening intro:

Alex really enjoyed helping out and he attended sessions on his own including iPhone development and file system encryption, and he got to play werewolf for the first time.

I've been meaning to blog about this for a while now: thanks to Alejandro Abdelnur, the long awaited ROME v1.0 RC1 is now available for testing.

I've already updated ROME Propono (changes in CVS only) to work with the new release and I've done some testing, but more is needed. I hope to test with Roller and with Blogapps once BarCamp RDU is over.

Joe Gregorio: Wow, the local area is really hopping these days, check out the 14 upcoming conferences, camps, workshops and events. Here's some video from the just passed RTP Startup Weekend, we've got coworking sites popping up, and of course a blog to cover it all.

That blog that Joe mentioned is new, NBC 17's 30threads.com, which launched last night at a very well attended blogger, beer and BBQ bash in the Edge Office coworking space in downtown Raleigh. The site is both a community aggregator and a blog authored by local/social media superheros Wayne Sutton and Ginny Skalski. Congrats to Ginny, Wayne and NBC 17 on a great launch and what looks to be a great new community site like no other in the Triangle.

If you are one of the 250 lucky folks registered for BarCamp RDU 2008, then you are invited to a party! BarCamp RDU attendees, please join us at Tyler's Tap Room (map) in Durham's American Tobacco Historic District this Friday night to meet, greet and celebrate BarCamp eve with us. We'll be providing beverages (beer, wine, sodas, etc.) and light snacks (chips and salsa). See you there!

And of course, the party would not be possible without the generous support of our most excellent sponsors: BlueStripe Software, Canonical, Carborro Creative Coworking, Design Hammer, Edge Office, IBM developerWorks, iContact, Lulu.com, Montie Design, OpenNMS.org, Red Hat, rPath and Viget Labs.

BarCamp RDU 2008 is one week from today and it's shaping up the be the biggest and I hope the best BarCamp RDU so far.

Here are a couple of notes for attendees:

Check the attendee list! On July 21, we decided we had budget and space to register everybody on the waiting list. If you were on the waiting list you are now registered to attend.

Remove yourself if you can't attend. If you registered but cannot make it, please remove your name from the list. For planning purposes, we need to have as accurate a count as is possible.

Propose sessions in advance. If you are interested in initiating or attending a session on a specific topic, then go right ahead and add your topic to the Proposed Sessions list.

Oh, and if you are interested in helping out with preparations or on the day of the event, then please let us know (dave.johnson at rollerweblogger.org or wayne at wayne-sutton.com)

And one final note. BarCamp RDU would not be possible without the very generous financial support of our sponsors and our host. So...

Thanks to the BarCamp RDU 2008 sponsors!

After spending a couple of hours with iUI this week, I've put together the beginnings of an iPhone style interface to Roller. So far, I've been able to do everything I need to do by making a couple of changes in Roller's struts.xml and adding two new JSP pages -- no Java code required (yet). This screenshot shows two of the three screens I have created so far.

I wrote and illustrated a detailed reference card covering RSS 2.0, Atom, AtomPub and the MetaWeblog API for the DZone RefCardz project. The six page "card" includes diagrams of the elements in the feeds, a synopsis of AtomPub protocol and coverage of ROME -- the same stuff you'll find in my book RSS and Atom in Action.

It's a free download, but you have to register with DZone.com to get it. While you're there check out the other reference cards they have. They've got some great ones, including great one for Glassfish.

Here's the link:

Via Roller web UI. It's not the most pleasant experience, pinching and scrolling around to move from title to content and then down the page to find the post button, but you can post to Roller from an iPhone. Seems like you could throw together a pretty nice iPhone interface for Roller using iUI. Who needs Android, J2ME, etc. when you can just use the web?

Just a gentle reminder that BarCamp RDU 2008 is coming soon. And one request. We've got 209 people registered and 31 on the waiting list so please help us out and if you registered but cannot make it, please remove your name from the list.

If you are interested in helping out with preparations or on the day of the event, then please let us know (dave.johnson at rollerweblogger.org or wayne at wayne-sutton.com)

I'm sorry to say that I participated in the iPhone launch debacle yesterday. I wrote up the frustrating and somewhat embarrassing timeline for a buddy of mine. You might find it interesting, so here it is:

Friday, July 11, 2008

6:45AM I arrive at AT&T store at Triangle Town Center mall (Raleigh, NC)
7:50AM 33 people ahead of me, ~150 people behind me in line
7:55AM AT&T rep tells us that they have 15 iPhones, but they'll take orders
8:00AM I leave for Apple store at Crabtee Valley Mall
8:20AM I arrive at said store, line looks to be greater than 200 people
9:00AM The line moves and is making slow progress
10:00AM line stops moving for over an hour because "activation servers are down"
10:05AM I've got my laptop, so I sit down and start coding (w/free Apple WIFI)
11:30AM The line starts moving again. scoot, code, scoot, code...
12:50PM I stop coding because laptop battery power is dead
1:00PM I attend a half-hour meeting via telecon
1:40PM I finally get into store, Apple rep helps me
1:50PM Apple rep helps me, gets "IRU account not supported error message"

I call AT&T, they tell me that I have a special "flag" on my line and they are not allowed to remove it via phone, and I MUST to upgrade my iPhone at the AT&T store -- i.e. wait 5-7 days for delivery from AT&T.

So, I call AT&T again and get another rep who tells me that they CAN remove the flag over the phone, mumble, mumble and then my cell phone connection drops.

2:20PM Apple puts me in a special AT&T problem line
2:40PM Apple rep calls AT&T, gets them to remove flag
2:50PM Apple rep will hold my iPhone until AT&T calls me to confirm flag removal
2:55PM Cheers erupt as the customer who was 1st in line at 8AM finally gets activated
3:00PM I leave empty handed but with a promise that AT&T will call within 24 hours

I'm not going to try to analyze this; I'll leave that up to you, dear reader.

Update: Saturday, July 12, 2008

10:00AM Call AT&T to ask about status, they blame Apple for problem saying only Apple stores had problems yesterday.
10:25AM AT&T tells me they are now issuing a "billing ticket" to ensure that all flags were dropped from my account. They say I'll have to wait up to 4 hours before it has taken effect.
2:25PM Apple store won't test the activation process over the phone so I make the half-hour drive to store only to get the same "IRU account" error.
2:45PM Call AT&T from parking lot, they tell me sorry things are taking longer than expected, we'll call you ASAP. I drive home empty handed again.
5:00PM Call AT&T to complain to a manager about the broken 24 and 4 hour promises. He tells me problem is on Apple side and if I ordered a phone at the AT&T store everything would be fine (in 5-7 days). He says there is no telling when they'll finally clear the flag on my account, so just keep on waiting.

Update: Sunday, July 13, 2008

11:30AM Still no word from AT&T so I called them and they said the flag problem had been resolved. I asked how I could be compensated for all the wasted time they caused me, misdirection and multiple broken commitments they said "we're not offering any compensation for iPhone problems." The AT&T rep also blamed Apple for all problems and said I should have bought from the AT&T store
12:20PM Arrived at Apple store, got my phones

Check out Tim Bray's Atomic Monday post for a summary of recent developments in the world of AtomPub protocol and Atom format. With the uptick in interest in Atom and especially AtomPub protocol's usage in mainstream APIs from Google and Microsoft, I wonder if if would make sense to update RSS and Atom in Action.

The bulk of the book is up-to-date, for what it covers. RSS and Atom haven't really changed and, though the book came out before the spec was finalized, the AtomPub material is basically sound. The ROME material is still current too.

What's missing are all of the new developments: a dozen or more new AtomPub based APIs from Google (GData and OpenSocial) and Microsoft (Live and Astoria) and new tools like Apache Abdera (incubating). Not to mention Windows RSS Platform 2.0 and ROME 1.0 (which is coming soon). Updating the book to cover all of those topics would be quite an endeavor and I'm not sure it's the right approach to covering AtomPub. What do you think?

via Jim Grisanzio: Chris Phelan has done evaluations of JSPWiki and XWiki for use on the OpenSolaris.org site. Based on his 32 requirements, XWiki came out on top.

On balance, XWiki wins by virtue of having better support for management, searching, page taxonomies, virtual servers, content export and language translation/localization support.

JSPWiki has slightly better support for identifying orphaned pages and accesskey support (XWiki 1.4 will have support for access keys).

Confluence was not considered because requirement #0 is "the software must be free and open source," which seems like a reasonable request when selecting software for an open source community site.

I'm still working through my backlog of Latest Links posts. First up, the OpenSocial links. I'm following OpenSocial closely because OpenSocial support is one of the key features of the new project I'm working on (Project SocialSite).

There were a bunch of OpenSocial related sessions at Google's I/O conference and they're all online. I especially like this one, OpenSocial: A Standard for the Social Web, which includes Google's Pat Chanezon discussing Project SocialSite, starting at 43:07 and on slides 70 and 71:

Here are the links:

• Google I/O Sessions
  Speaker videos and slides for each. Lots of OpenSocial sessions
• OpenSocial Summit Presentations, Notes, & Videos
  Very nice summary of summit via links
• AOL Joins OpenSocial
  "AOL’s first steps will be to implement Gadgets on myAOL.com."

I'm also following Google's FriendConnect pretty closely, which is a model similar to Project SocialSite -- but, and this is my opinion, for smaller sites that do not want to build and manage their own social graph. It's conceivable that Project SocialSite could one day implement FriendConnect, thereby allowing folks from a Project SocialSite-backed site to join into FriendConnect based sites. At any rate, here's what I've read about Friend Connect so far:

• Google Code Blog: How Google Friend Connect Works
  "how it works on the Friend Connect side with respect to users' information."
• Marc Cantor on Friend Connect, et. al. - I do not compromise
  "They’re all keeping their member’s data on their servers, while sending out tentacles to mesh in with as many outside sites as they can."

Here's another link blog post. In this one I'll explain why my del.icio.us feed is full of guitar tabs. I've been spending some time Away From Keyboard and near to fretboard. Since my 11 year old son Alex is learning guitar I've been doing the same and making some good progress. I've noodled around on bass for years, but never spent much time with guitar. I've always known the basic chords, but that's about it. Now I've finally learned how to string and "sing" at the same time and so I've been looking for good, fun and easy songs to play. Here are the ones I've found so far, straight from my bookmarks feed:

• Animals – (House of the Rising Sun tab)
  
• Connells – 74-75 tab
  
• Connells – Fun & Games tab
  
• Costello, Elvis – (What's So Funny tab)
  
• Creedence Clearwater Revival – (Who'll Stop the Rain tab)
  
• Creedence Clearwater Revival – (Lodi tab)
  
• Creedence Clearwater Revival – (Have You Ever Seen the Rain tab)
  
• Cure – (Love Song tab)
  
• Diamond, Neil – (Solitary Man tab)
  
• Grateful Dead - (Friend Of The Devil tab)
  
• Grateful Dead - (Ripple tab)
  
• REM – (Driver 8 tab)
  

You can probably guess my age now

Here are a couple more kinda sorta related links from the feed.

• Interactive Guitar chord explorer
  Very nice Flash interface for viewing chords, playing them, etc.
• Live review: R.E.M. drives the past into the present
  REM "has come full circle, treating the old and new with the same vigor and precision"
• YouTube - Connells @ Borders: 74-75
  2000 or 2001, in Chapel Hill, NC

I bookmarked that REM review because we attended that show last week. We took a bunch of kids and had a blast. REM played a bunch of their very early songs like 7 Chinese Brothers and Pretty Persuasion. The kids (from 5 to 11 years old) danced like fools on pogo-sticks the whole time.

And finally, here's something here's something not in my bookmarks feed; the Epiphone G-310 I bought for about $230 last weekend.

It's time to catch up on blogging and I'm going to start by going through my backlog of links and adding some commentary, but not in this post; these are miscellaneous links that don't fit nicely into my other posts.

• Slashdot | Why Google Should Embrace OpenOffice.org
  "If Google really wanted to deliver a knockout punch to Microsoft, it would integrate OpenOffice with Google Docs" -- and pump some money into OOo development
• Headius: The Power of the JVM
  "And while JRuby and Groovy will probably spend the next few months one-upping each other, we've both proven something far more important: the JVM is an *excellent* platform for dynamic languages. Don't let anyone tell you it's not."
• SpringSource Blog - Open Source, Open Strategy
  My 141 char summary: open source good, but we need money. we won't relicense existing parts, but we'll GPL the full-stack so we alone can ride it to the bank
• Kohsuke Kawaguchi: GlassFish v3 just got embeddable
  "GlassFish glassfish = new GlassFish(); glassfish.minimallyConfigure(8080);"
• Derby: Using the bulk import and export procedures
  closest thing to mysqldump in Derby land
• Core team statement on replication in PostgreSQL

• Distributed Caching with Memcached
  Nice how-it-works article on memcached.

Nick Lothian tweeted about this JavaOne presentation on LinkedIn because it mentions the ROME RSS/Atom feed parser. I'm really sorry I missed it at JavaOne. What's particularly interesting to me are the diagrams that explain how the LinkedIn architecture has evolved to scale up to 22 million users. Here's an example:

After attending two great BarCamps here in Raleigh, I'm just as pleased as punch to be helping out on the BarCamp RDU organizing committee this year.

We put out the call for sponsors a couple of weeks ago and thanks to some generous sponsors including iContact, Canonical, rPath, Brian Russell, OpenNMS and Montie Design we quickly met 65% of our small budget. Now we need to wrap things up, money-wise. If you'd like to get some great positive exposure among the best and brightest in the local tech community by sponsoring, here's your chance.

If you're interested in sponsoring or helping out as a volunteer, contact me via email for more info (dave.johnson at rollerweblogger.org). If you're interested in attending, you'll have to add your name to the waiting list -- at this point we're sold out.

Looks like we made it to the final round of the Enterprise 2.0 LaunchPad competition and so Project SocialSite will be one of the five projects that will "present their ideas in front of an audience of creators, evangelists and adopters of cutting edge technologies who will provide feedback in real-time and decide the winner." Thanks to all who voted for SocialSite.

And in other news, Arun Gupta has put together a very nice ten minute screencast that shows Project SocialSite in action.
