Web 2.0 Patterns Wiki

Dragos Manolescu — Wed, 09 Jul 2008 16:23:13 GMT

Last week a group comprising Felix Nyffenegger, Judith Bishop, Duane Nickull, Marco Brambilla, Marco Egli, Michael Mahemoff, Patrice Pelland, Petri Selonen, Steve Burns, Wolf Logan, and Wei Wei joined me and Joe Yoder at the Web 2.0 pattern mining workshop at ETH Zuerich.

Several clusters emerged around the workshop's presentations. For example, Patrice and Wolf's coverage of gadgets and gadget platforms pushed our exploration to the UI/glass. Some of the common traits include:

Provide an open platform
Support several technologies (JavaScript, Silverlight, Flash)
Package applications as gadgets
Extend instrumentation to include the client
Provider feeds raw content, users create personalized mashups

Also on the first day Duane and Steve's coverage of cloud-hosted services brought forth the following:

Execution context awareness
Scale services up and down

Add more capacity quickly, only when you need it
Remove capacity when you no longer need it

Leverage analytics-increase awareness of server utilization
Abstract out the hardware

Push into the cloud
Leverage virtualization

On the second day Michael's focus on gadgets and OpenSocial directed us to paleosocial patterns, while Felix and Marco's coverage of Web 2.0 site navigation put on the table vizualizations (e.g., debategraph.com, tafiti.com), presentation shifting (e.g., piclens.com, Photosynth), and others.

During the workshop we also designed a web-based video player that surfaced many of the solutions we looked into. Besides reminding us what it's like to use a real blackboard this exercise helped cluster some of the emerging themes:

Key-value store: Amazon Dynamo/S3, BigTable (Google)
Streaming: Hulu, YouTube streaming (not Flash)
Client time synchro service: NTP, MMORPG
Social network integration services: Oauth, OpenID/Passport
Mash-up engine: PopFly, Yahoo! pipes
Monetization (social cash -> $, analytics, instrumentation): AdSense, witkey.com, SiteMeter, Elance
Video: Vime, Nicovideo.jp, Jaman.com
Mood: Musicovery, Yahoo! IM, Nabaztag.com
Friend states: Twitter
IM: Facebook/MySpace, Twitter, Shoutbox
Recommendations: Tuneglue, Netflix, Facebook

We are planning on fleshing out some of the emerging patterns as a a distributed, collaborative endeavor. We have a wiki site to provide the locus of collaboration for this work. For the moment only the folks who attended the workshop could add and change the content. I expect that to change as the content shapes up so stay tuned.

Web 2.0 Patterns

Dragos Manolescu — Fri, 21 Mar 2008 16:46:08 GMT

During the last decade software patterns emerged as one of the most successful forms of reuse. The Gang of Four 23 Design Patterns, the POSA Architecture Patterns, Fowler's Enterprise Application Patterns, or the xUnit Test Patterns (to name just a few) changed in a fundamental way the way we craft software.

If you are involved with applications that employ:

Folksonomies
Microformats
REST, XML, or JSON-based APIs
AJAX and RIAs
Syndication and aggregation (RSS, Atom)
Mashups
Blogs, wikis, social media, or other types of user-generated content

and are interested in patterns covering these topics then join us at the Web 2.0 Pattern Mining Workshop at the TOOLS-Europe 2008 conference, the 46th International Conference on Objects, Models, Components and Patterns. Participation in the workshop is open to anybody who could contribute to Web 2.0 patterns. See the call for participation online and drop me a line if you have questions.

Final Call For Papers

********************************************************************
IMPORTANT DATES

February 18, 2008: Paper Submission Deadline
July 9-13, 2008: Conference
********************************************************************

[we apologize for duplicate receipt of this message]

EuroPLoP is the premier European conference on patterns. The
conference offers a variety of tracks and workshops that allow you
to learn about patterns, to receive feedback on your own work, and
to discuss with fellow enthusiasts. It is a unique venue to exchange
knowledge about best practices and learn from other experts in
various fields. EuroPLoP 2008 will be held July 9-13, 2008 in the
Irsee Monastery, Germany. Join us for an experience that will
combine outstanding technical events with a visit to the lovely
Bavarian countryside.

EuroPLoP accepts papers containing patterns or pattern languages as
well as experience reports and other papers related to the theory
and use of patterns. For the first time, EuroPLoP 2008 will offer
thematic tracks allowing practitioners and researchers from a
specific domain to exchange knowledge.

In previous years, thematic clusters evolved implicitly including
areas like:

- Software development
- Software design and architecture
- Software management and development processes
- Human computer interaction
(e.g., user-interface aspects or novel modes of interaction)
- Education
(ranging from professional training to classroom teaching)
- Business and organizational questions

This year, we like to invite you to champion one of these thematic
areas or propose new topics by submitting a proposal for a thematic
track.

Several open tracks will be retained to provide for new topics and
topics outside the thematic tracks.

             *******************************************
                           THEMATIC TRACKS
             *******************************************

Starting in 2008, EuroPLoP hosts thematic tracks that put a special
focus on hot topics. In 2008, the tracks are:

Pragmatic and systematic approaches in applying patterns

Organized by Paris Avgeriou (University of Groningen, The Netherlands),
Neil B. Harrison (Utah Valley University, USA), and Uwe Zdun (Vienna
University of Technology, Austria)

Patterns for Collaboration Technology and Processes

Organized by Stephan Lukosch (FernUniversitaet in Hagen, Germany),
Gwendolyn L. Kolfschoten (Delft University of Technology, the
Netherlands), Gert-Jan de Vreede (Institute for Collaboration Science,
University of Nebraska at Omaha, USA) and Robert O. Briggs (Institute
for Collaboration Science, University of Nebraska at Omaha, USA)

Patterns for Collaboration Technology and Processes

Organized by Symeon Retalis (University of Piraeus, Greece) and
Christian Kohls (KMRC - Knowledge Media Research Center, Tuebingen, Gemany)

Please visit the EuroPLoP web site http://hillside.net/europlop and the

goals of the specific thematic tracks.

             *******************************************
                        SUBMISSION CATEGORIES
             *******************************************

Submissions should fall into one of the following categories:

Pattern papers

Short papers (5 to 10 pages) containing one or more patterns, longer
pattern languages (about 15 to 20 pages) or sequences and
work-in-progress papers. All accepted papers will receive in-depth
shepherding by an experienced pattern author before the conference.
Newcomers papers may receive further shepherding at the conference
itself.

Proven practices papers

Papers about the craft of writing software or patterns, papers about
the concept of patterns and proven practices in general, case
studies of patterns in action, or papers about software development
communities of practice.

Focus group proposals

Focus groups are free-format discussion groups or workshops lasting
between 3 and 6 hours. They are designed to bring together people
who are interested in a challenging topic related to patterns or
proven practices. Non-conventional ideas such as goldfish bowls are
welcome. Organizers of thematic tracks are encouraged to submit a
focus group proposal that covers parts of their topic.

             *******************************************
                         CONFERENCE STRUCTURE
             *******************************************

The main track of EuroPLoP will be organized as a series of writers'
workshops where authors work together to improve their papers.
Before pattern or other papers are accepted for a writers' workshop,
they are shepherded (non-anonymously). This means that an
experienced author will discuss your submission with you, so that
you can refine your paper prior to the conference. All submissions
will be peer-reviewed.

The EuroPLoP proceedings are published in book form after the
conference.

Papers discussed at writer's workshop at this conference qualify for
submission to the new journal "Transactions on Pattern Languages of
Programming" published by Springer. See http://hillside.net/tplop/ and
http://www.springer.com/home/computer/lncs?SGWID=5-164-2-470309-0Final

Guidance on Model-View-... Variants

Dragos Manolescu — Tue, 28 Aug 2007 07:27:00 GMT

Rcently I've been part of several conversations on the differences between Model-View-Controller and Model-View-Presenter. While reviewing the original articles (i.e., Krasner + Pope and Potel) which I read years ago I ran into many different, and sometimes incomplete or even incorrect interpretations and renditions. Following this experience I bet that MVC and MVP are the most misunderstood popular patterns. Answers to questions such as Why have you used MVP? or What's are the salient traits that determine whether a triad is still an MVP? are leading me to believe that many folks would welcome guidance about these patterns (including their relationsip). What's the best side by side MVC/MVP explanation you've seen? Would something like that make your life easier?

PLoP 2007 Call for Participation

Dragos Manolescu — Sun, 05 Aug 2007 00:38:00 GMT

Here's the announcement from my fellow Hillsider (and long time friend) Joe Yoder. Anybody who's serious about writing, reviewing and refining patterns should have at least one PLoP under their belt.

*********************************************************************
CALL FOR PARTICIPATION (final)

14th Conference on Pattern Languages of Programs (PLoP 2007)

September 5-8, 2007 - Monticello, Illinois, USA
http://hillside.net/plop/2007/

*Early Registration till 19th August*
http://hillside.net/plop/2007/index.php?nav=registration
*********************************************************************

*About PLoP*

Pattern Languages of Programs (PLoP™) conference is a premier event for
pattern authors and pattern enthusiasts to gather, discuss and learn
more about patterns and software development.

Patterns authors and non-authors will find in the different PLoP
activities (Writers' Workshops, Writing Groups, Focus Groups, BoF
sessions, BootCamp, Games) many opportunities to meet and learn more
about patterns and pattern writing.

As a whole, the conference provides a friendly and effective environment
to give and get feedback, to share expertise, and to allow the
participants to improve their knowledge about patterns.

*How To Participate*

If you are not an author of a paper accepted for PLoP'07, you can still
participate actively by enrolling a *Writing Group*, or proposing a
*Focus Group* or *BoF*.

*Writing Groups* are primarily for participants willing to start writing
their first pattern, or to continue evolving their work-in-progress.
Writing groups aim at providing authors the opportunity to work on the
their patterns in an interactive session mentored by an experienced
author specifically assigned to each group.

Papers on the writing groups are typically papers that, at the end of
the shepherding process, were considered that would profit more from an
interactive session to work on the paper than from a writers workshop.

After the work done in the writing group, some papers will be selected
to be discussed in the final session of a Writer's Workshop at PLoP'07.
Another possibility is to further evolve them after PLoP'07 and submit
to the Mini-PLoP at OOPSLA'07, a full-day Writers Workshop.

*Focus groups* are free-format discussion groups or workshops aimed at
bringing together people interested in a hot topic related to patterns
or proven practices, for a period of about two hours.

These sessions might focus on very different topics and issues related
to patterns, ranging from writing to using, organising, or adopting
patterns. Focus group proposals should include a brief description of
the topic to be addressed, objectives, format, conditions for
participation (e.g. invitation, submission, free, etc), and a schedule
outline. Proposals addressing interdisciplinary topics and topics from
other domains than software development are especially encouraged.
Non-conventional formats are welcome.

Focus group proposals are reviewed by the program committee. Focus group
leaders are expected to write a report to be part of the final
conference proceedings.

*BoF ('Birds of a Feather')* is a shortening of the proverb "Birds of a
feather flock together.", meaning that people (birds) of the same kind
or interest (of a common feather) enjoy spending time (flocking) together.

BoF sessions are informal meetings, usually scheduled and organized
lately or even on site, where people group together based on a shared
interest and carry out discussions without any pre-planned agenda.
Everyone may propose a BOF session to the conference chairs, on or
before the conference.

*How to submit*
To participate please submit your idea or work-in-progress till *17th
August*, by email to plopsubmissions@hillside.net. The submission can be
as minimal as a 200-word abstract or a full paper under development.

*How to register*
PLoP online registration has opened on May 15 and will be possible till
August 19, 2007. We strongly encourage early registration for better
room arrangements and conference service.
