O’Reilly Open Source Convention Calls for Innovation
OSCON Proposals Invited
Sebastopol, CA—Dec 15 2008—Now that big business has grasped the principles of open source, the open source community can get down to business. New times demand new ideas, and OSCON, the O’Reilly Open Source Convention, has opened its call for innovation. O’Reilly Media and program chairs Allison Randal and Edd Dumbill invite proposals for tutorials, sessions, and panels for OSCON, happening July 20 - 24, 2009, in San Jose, CA.
“Accomplishing great things with limited resources is the open source way of life,” says Allison. “We hope you’ll join us and share your solutions. We live in a time of enormous challenges: economic, environmental, political, and social. Open source software and the open source community have much to offer as we work to solve the world’s problems, to keep moving toward a better future.”

Sean Michael Kerner sums up OSCON 2008:
Tim O’Reilly (you know the guy who runs the big tech publisher) is still bullish on the prospect of open source. After 10 years of running the OSCON conference he still sees innovation on the horizon.

Slashdot on some of OSCON’s greatest hits:
An anonymous reader writes “Infoweek wraps last week’s event with Inside The OSCON 2008 Conference, which pulls together interviews with Mark Shuttleworth, Linux Foundation’s Jim Zemlin, MySQL’s Zach Urlocker and Sam Ramji, who directs Microsoft’s Open Source Lab. Best quotes: ‘We will make a significant attempt to elevate the Linux desktop to the point where it is as good or better than Apple,’ from Shuttleworth; and ‘If I would start a business tomorrow I’d do it in the netbook marketplace. I’d build a dead-simple $200 device that targets sports fans, women over forty,’ from Zemlin.”read more
While all the other “nytimers” are running around having interesting discussions, I thought I’d do a quick blog post.
Yesterday’s OSCON sessions were great overall, but there were a couple that really stood out for me.

Serdar brings us all the way to Friday:
There’s a part of me that thinks Sam Ramji, director of Microsoft (NSDQ: MSFT)’s Open Source Lab, has the worst imaginable job at Microsoft. But he doesn’t see it that way: Where other people would see such a position as being crushed between two wholly opposed forces (Microsoft and open source), Sam sees it as a way to build a bridge that didn’t exist before — and maybe to transform Microsoft all the more from within.

Aside from having one of the niftier names in the industry, Joe “Zonker” Brockmeier has a pretty nifty job, too: He’s the openSUSE Community Manager at Novell (NSDQ: NOVL), where he oversees the folks that help make what will ultimately turn into the next version of SUSE Linux Enterprise. I grabbed a few minutes of his time to follow up on things I’d talked to him about back at theRed Hat (NYSE: RHT) Summit.
Thursday, and the prolific Serdar continues his coverage.read more
On Wednesday I sat down at OSCON with a slew of people from Sun Microsystems to talk about key parts of their empire, both new and old. First up was Zack Urlocker of MySQL (whom I’d observed at the Monday Participate 08 panel), one of the newest additions to the Sun galaxy, and an acquisition that’s caused a great deal of worry amongst existing MySQL users.

Let’s rewind a bit. My Monday afternoon at OSCON 2008 was taken up by “Participate 08,” a Microsoft (NSDQ: MSFT)-sponsored discussion panel chaired by a whole panoply of folks — including, yes, an open source liaison from Microsoft. The whole thing was neither a “corporate apologia” (as one wag put it from the audience) nor a pile-on where Microsoft got the worst of it. Their approach was only one of a diversity of perspectives, and sometimes not even the most eyebrow-raising.

We loved reading Serdar Yegulalp’s opinion on OSCON, especially since he started by saying, “O’Reilly knows how to treat their guests. Not only was the registration process wonderfully painless (+1 points), not only was there wireless throughout the convention center (+3 points), the tables in the lecture halls had power strips (+5). My notebook gets around 4-5 hours of battery life, but not having to run out of juice in the middle of a lecture is a huge help. (The giant Buddhist temple bell outside the convention center that rings “without warning” was another nice bonus.)”read more
Its good to be back in Portland for my favorite geek convention: O’Reilly’s Open Source Conference. The overcast sky in Portland is making it a little easier this year to focus on the plethora of excellent speakers and sessions. The first session to really grip and and speak to me was Rabble and Kellan’s “Beyond REST? Building Data Services with XMPP PubSub” presentation.
They started out their presentation stating that they were not “Jabber Heads”, but that they were in the business of building web sites. For Rabble and Kellan, Jabber presents one more tool in their huge tool-chest to build web sites. Jabber wasn’t designed to be a part of a functioning web site, but they insist that it works great for building social web sites that require many people to be notified of updates.
For example, Kellan talked about FriendFeed, a site that lets their users know when their friends share new items. In this example, Kellan pointed out that FriendFeed polls Flickr 2.9 million times in order to check on updates for 45 thousand users. And of those 45 thousand users, only 6.7 thousand are logged in at any one time. This of course, its a poor way of checking for changed content. Kellan says: “Polling sucks!”
To solve this problem its key to leave standard REST web services behind and find a way to use message passing, which is a direct communication way of notifying users of changed content. The open and mature infrastructure that Rabble and Kellan found to use for this service is Jabber. Jabber has 10 years of experience of passing messages around the internet and has been embraced by many companies including Google.
XMPP, Jabber’s protocol, works well for message passing and does not have many of the problems/limitations of HTTP:
Given this, Kellan and Rabble decided to piggy-back a notification system on Jabber by sending XML fragments using a PubSub paradigm. In this context, PubSub is a simple method for passing XMPP pubsub stanzas via Jabber. PubSub is nothing more than a convention for how to send XML via Jabber, including a method for embedding ATOM fragments in the XML.
Rabble presented using XMPP for FireEagle, Yahoo!’s new personal geolocation service that allows users to provide their current location to other users. For a few users and a few updates you can paginate the data stream into RSS/atom feeds. But once you have more than a few users and frequent updates a paginated stream cannot keep up. What if a user publishes more updates than can an RSS feed can capture? Updates get lost — and for applications using FireEagle missing an update presents a critical flaw. Using a system like XMPP, FireEagle can rely on Jabber to deliver all the updates — exactly what Jabber was meant to do.
Kellan also applied XMPP/PubSub to Flickr and how a Flickr update “Firehose” might work. If Flickr sends a ~2k an atom enriched packet for each new public picture posted at a rate of 60 updates a second, it would take roughly a megabit of traffic. Even a normal DSL line can handle one mbit of traffic, so the network effects are manageable on this level, compared to the polling system that FriendFeed uses. (Kellan also points out that FriendFeed is not doing anything wrong at all — the current web service centric model is simply insufficient for this type of service.)
To deploy your own message passing service based on XMPP/PubSub, you’ll need to follow these 4 easy steps:
Pretty simple, overall! The beauty of this approach comes from the fact that all off-the-shelf components were used to build this new notification system. No new magic technology is being created to enable this system, which is a personal metric of mine for determining the likelihood that a new system will succeed.
It’s clear that REST web-services provide the heavy lifting for many Web 2.0 sites, but its also clear that REST and its inherent polling mechanism isn’t the best way of building a user notification system. With social networking sites not about to fade away, we’re going to see an increasing need for capable message passing sites. And since Jabber is a well established and supported system, it only makes sense to piggyback on this great technology. Thanks for the awesome presentation Rabble and Kellan!read more
