Java talks at this year's OSCon

Posted by daniel on February 7, 2005 at 8:46 AM PST

Call for papers deadline Feb 13 for the O'Reilly Open Source Convention

There are many open source Java projects. Submit a proposal for a
talk or a tutorial about your favorite for this year's O'Reilly href="http://conferences.oreillynet.com/os2005/">Open Source
Convention. OSCon is held in Portland, OR August 1-5 but the href="http://conferences.oreillynet.com/cs/os2005/create/e_sess">call
for papers closes February 13.

OSCon is a challenging forum for Java developers. Paul Graham
belittled Java during his keynote and Tim O'Reilly received applause
when he reported that the overall market for Java books has
declined. Tim was just summarizing the numbers for various technologies and not making a political statement.

All that aside, there was a very healthy Java track last
year. Couple that with the fact that there is a large intersection
between Java developers and open source developers (although the
definitions of open source may differ) and OSCon is a fun conference. There is a limited amount of space for Java presentations, but take some time this week to craft a compelling proposal.


Stuart Sim writes href="http://weblogs.java.net/blog/simstu/archive/2005/02/quality_bugs_me.html">
Quality Bugs Me in today's
Weblogs
. He muses that a bug is often a "mismatch between
expectations and the delivered software because the requirements were
so poorly documented or the functional domain was not clear to the
team."

Thanks to some work from Tim Boudreau, href="http://weblogs.java.net/blog/timboudreau/archive/2005/02/jnn_just_got_pr.html">
JNN just got prettier (at least on the mac). " Having a couple
evenings to kill in a hotel room, and needing to do a bit of coding to
keep myself sane, I wrote some UI and keyboard usability improvements
to JNN, James Gosling's RSS
reader (screenshot in blog). I hope you'll agree the results are
pretty slick. Especially if you're using a mac, please give it a try."

In href="http://weblogs.java.net/blog/jonathansimon/archive/2005/02/bad_design.html">
Bad Design, Jonathan Simon provides A really good example
of really bad design. The feedback poses thoughts on why it is
so.


In Also
in Java Today
, Andy Hunt points to an article that, at first
blush, may not seem to have anything to do with the programming
life. He writes that The Christian Science Monitor article href="http://www.csmonitor.com/2005/0127/p01s03-woeu.html">The cure
for traffic chaos? Remove the signs, lines, lights."says local
authorities in London are about to unveil a radical solution to
traffic congestion and pedestrian safety. They're planning on
removing all of the conventional road markers: traffic lights, white
lines, guardrails, sidewalks, etc., and create a single shared
space
for everyone, motorized or not. In effect, by upsetting
the status quo, research (and a few pilot projects) has shown that
drivers suddenly become much more attentive and aware. They can't
just roar through the light on mental autopilot when there is no
light. They have to watch their entire surroundings, make eye contact
with pedestrians, and so on. They have to become engaged to be
effective."

Bitwise manipulation seems like the arcane art of assembly-language
programmers and the most hard-core of performance freaks, but Glen
Pepicelli reports that it is possible and even desirable to use these
techniques in Java. In "Bitwise Optimization in Java: Bitfields,
Bitboards, and Beyond", he notes Java's use of boolean flags and new
bitset features in J2SE 5.0, then dives into the example of
representing a Chess board as bitsets, and how some expensive
operations can be converted into fast logical and mathematical
manipulations.

, help Sun choose the best selection of desktop
sessions for this year's JavaOne conference. Take a few minutes to
fill out the href="http://jdl.sun.com/webapps/survey/display?survey_id=4745">JavaOne
2005 Desktop Track Survey featured on the front page of the href="http://community.java.net/javadesktop/">JavaDesktop

The NetBeans
community points to a new article on href="http://java.sun.com/developer/technicalArticles/JavaLP/netbeans41EA2/">
NetBeans IDE 4.1 which reports that this "new release allows
developers to not only develop applications in the web tier but also
includes Enterprise JavaBeans (EJBs) and web service development
capabilities."


Cowoc asks for href="http://forums.java.net/jive/thread.jspa?messageID=10766&tstart=0#10766">
rt.jar with debug symbols in today's href="http://forums.java.net/jive/index.jspa"> Forums. "I
feel it would be invaluable to be able to get line numbers with
stack-traces when an exception is thrown by JRE code. Can you make
rt.jar with debugging symbols available for Tiger update 1 and
Mustang?"

Zander takes issue with those asking Sun to href="http://forums.java.net/jive/thread.jspa?messageID=10733&tstart=0#10733">
create a datepicker. "Asking Sun to donate even more resources so you
don't have to go out and find a datepicker from one of the dozens of
providers does not sound unreasonable? I could also say that if you
write one datepicker twice you could have said to one of those
companies to do it in an open source manner so two companies can
divide the costs for one component. "
