CommunityOne/GlassFish Day Report

Posted by arungupta on May 7, 2007 at 10:15 PM PDT

This is a long entry and reports on the CommunityOne opening session and GlassFish Day
opening session and lunch session with Jonathan and Rich. Feel free to skip into
later section highlighted by bold and underlined words.

Opening Session

Even though JavaOne kicks off
tomorrow, CommunityOne
started earlier today. This was a FREE event in Moscone Center

Rich Green gave the opening session
in the morning and said that it
allows every body to communicate at a denser rate than you can do in the virtual

Rich then invited Tim O'Reilly, Founder and CEO,
O'Reilly Media to talk about
open source and community. TimO started by asking two questions:

How many of you use Linux ? - Almost 80% of hands showed up.

How many of you use Google ? - Almost 90% of hands went up.

And then he compared that Google is the most widely deployed application but
NOT open source.

Yahoo, eBay,
wikipedia, Google - all use "Network as the
Platform". TimO then pointed that Sun is way ahead when
John Gage said "Network is the computer'.

TimO then explained the concepts of Web2.0 (even though he does not like the
term anymore :). At Sun, we refer to it as next generation Web application
development. The key features are: architecture of participation, rapid
development methodologies, perpetual beta and centered around user generated

He then invited Rich Green, Tim Bray, and
Ian Murdock and asked the following

  • How do you help developers in "harnessing collective intelligence" ?
  • How do you help developers in creating "live software" ?
  • How are you thinking about open source and open standards in the context
    of future data lock-in ?

There was an interesting discussion around these the term "user generated
content" and each of the participant gave their opinions. Ian quoted Jonathan
Schwartz "Computers are not the commodity, computing is". And commoditization of
computing brings the prices down. Rich talked about the gradient between formal
communication, such as phone call, and "user generated content" and how it's

The session then invited questions from the users and below is my transcript of
some of them:

Q. Is there a limit to what Sun will open source or is it merely a
question of timing ?

A. Rich: There doubtless can be an edge condition, but everything.
Open source our technologies, our intellectual property, with correct licenses,
is the right thing to do. This aligns with our business model. This isn't a
teaser, but this is our business model.

Q. What is Web3.0 likely to be ?

A. TimO: Probably a meaningless term. Most transformative is when
we stop typing, not just speech interface. But also gestual interfaces, such as
Wii. Lot of instrumentation, e.g. insurance company reading GPS data.
Continuation of web2.0 into an invisible computing fabric. Computers learn from
not what we say them to do but learn from what we do.

TimB: It's going to be really surprising.

Q. Is Sun looking to embrace other languages and technologies beyond Java
in the future ? Where does Sun see Java fitting in the Java ecosystem ?

A. Rich
: Java language and VM are two separate things. VM can host multiple
languages, for example JRuby. Pioneering steps we'll talk later this week.
Isolation layer between VM and language is an active play.

Tim: Sun really has to become good at where the developer is.

Ian: Developer platforms of choice are moving up the stack, are the
things down under (such as O/S) are relevant. Why does O/S still matter ? Even
though you are targeting higher level computing systems, at some level there is
computing system.

Q. How will user generated database to compete with proprietary dbs ?

Ebay has a built of database where open db cannot compete. Wikipedia and
Britannica. There will lot of battling who owns the first clicks.

Q. Client-side software to Flash or heroic efforts. Why Java (a simpler
solution) is not used ?

Rich: 23 hours, come back tomorrow.

Q. How do you see developers do open source and make money instead of big
companies taking our ideas and off-shoring our jobs ?

A. Rich:
Worrisome social artifact that there are so many people generating
content whose work is picked up by companies and make money. Sun is looking very
closely for compensating people if Sun monetizes on a product based upon content
generated by community. This is not a balanced fair playfield.

TimB: It's a global world, anybody in IT is in global business. But this
is a transition.

TimO: End of cheap out-sourcing. It's a transitional stage.

Ian: We are talking about building a platform, which enables other people
rather than the platform itself. Web platform is different in terms of how
business is built around it.

After the opening keynote, the attendees were floating between multiple
tracks such as
NetBeans Day,
GlassFish Day,
Web 2.0
and others. I attended first part of GlassFish Day.

GlassFish Day

GlassFish Day
was all about
, current state of GlassFish, the community, the ecosystem,
partners, where it's going, The
and lots of other related presos.

Karen Tegan Padir
kick started the event followed by
Eduardo Pelegri-Llopart giving the
state of GlassFish and a glimpse of where it's heading.


) is a good recap of the opening session.

There was a lunch session with Jonathan Schwartz and Rich Green. They both
started by thanking everybody for participating in the GlassFish community.

Rich mentioned that even though Bill Joy said "Innovation happens elsewhere"
but it happens
everywhere. He believes in keep giving away your technology. Jonathan added that
the reason we are so confident in giving away because we are confident at
producing more of them. And this is produced not by just Sun engineers, but our
customers, OEMs and the whole ecosystem.

Here is my transcript of some of the questions asked by the audience:

Q. How do Sun see small companies
to go open source ?

: Clear dividing line, who won't pay for the software. There are
folks where the cost of hiccups or downtimes way exceeds the cost of software.
The revenue stays, but the form changes in support contract. This a bright line.
Charge customers for the value add.

Q. For GlassFish, any stats on how much code is contributed by Sun
employees and community ? Is it growing ? Any benchmark targets ?

: Varies very widely depending on the area. Most of the TopLink Essentials
code comes from Oracle. jMaki, big chunk from outside. The new Web services support is
designed so that more contributions can be made easily. Guess is low-two-digits.

Jonathan: We are not Costco, not interested in bulk. We are interested in the
quality of innovation.

Rich: We don't have a plan. Skewing of content from inside vs outside.
Because we don't want to stop.

Jonathan: Open source is an aggregation of user generated content.

Q. Eclipse developers, expecting to move to NetBeans ? Is is strategy or
side-effect ?

: Side effect.

Jonathan: Inevitable side effect. Target demographic is Northward. Eclipse is a
brother in arms for us. We could've renamed NetBeans as Corona.

Q. Looked @ GF briefly, positioned as RI of JavaEE5.  Programming model
changes often, customer facing part of the application. Would not like to see not
that changed.

: Talk to Rod Johnson and Kohsuke on how they are adding Spring support
to JAX-WS. Extension points in mutliple layers of GF. For JavaEE6, how you can
take advantage of Spring and JRuby and other things. All of this shows that
programming model is indeed not changing but accommodating existing frameworks.

There were other interesting sessions in the day but I had to configure the
machines for the
that's opening tomorrow morning.
