SD West March 9-13, 2009
I'm speaking at SD West 2009,
on March 13th (Friday). I'm doing just one talk
this time around. It's another update to my
server talks from the last two years,
How To Build a Scalable, Multiplexed Server
Using NIO, Mark III.
This time I'll be concentrating on some
sample applications that you can build on top of
the NIO multiplexing framework.
Slides for this and other presentations can (or will) be found
here.
Information about accessing the code from my Subversion
repository is
here.
NIO Visualization Tools
You can find two GUI demo tools
that I developed a while back to help visualize
the way NIO Buffers and Selectors work.
These are ready-to-run JARs, just
do 'java -jar bufferdemo.jar' or
'java -jar selectdemo.jar' to run them. No need to
set the classpath. On Windows and Mac,
if things are setup properly, you can just
double-click the icon for the jar file.
Click here to download the demos.
Gotta Question?
If you have a question or comment
about NIO or any other subject,
feel free to contact me:
.
I'll do my best to get back to you in a timely manner
(within reason of course).
Note: If you don't hear from me within a few days,
try again. Emails from random people (that's you)
often get flagged as spam and I don't see them.
Also, I've occasionally not been able to reply to
a question because the sender's corporate mail
system won't let my response through.
Gotta Problem?
If you need help with an NIO problem,
or anything within my expertise, I can provide
consulting services worldwide. Please
directly and I'll make the pain go away.
Update: I'm now employed full-time, so
my availabilty for consulting projects is limited.
But I still may be able to help.
Upcoming Stuff
Not Much Right Now
I'm now working full-time at
Mark Logic Corporation,
which keeps me pretty busy. I haven't been doing
much speaking on the subject of NIO lately. If
you'd like me to give a talk about NIO, contact me.
Stuff You May Have Missed
March 3 - 8, 2008: SD West
I spoke at SD West 2008,
on March 5th and 6th. I gave two NIO talks
this time around. The first is entitled
What's New In NIO.2 about the new NIO
features that will be available in Java 7 (JSR-203).
The second is an update to my server talk from 2007,
How To Build a Scalable, Multiplexed Server
Using NIO, Mark II. Some improvements have
been made to the design with an eye to better
leveraging the concurrency APIs and improving
worker thread management.
Final slides for both presentations as well as the code
for the server prototype are available
here. There is
also information there about accessing the
Subversion repository for all the code.
March 19 - 23, 2007: SD West
I spoke at SD West 2007,
on March 23rd at 3:30pm. The topic was
How To Build a Scalable, Multiplexed Server Using NIO.
The slides can be found here.
This talk is based on experiences I've
had writing server frameworks using NIO on J2SE 1.4. I
updated the code used in the slides to make use
of 1.5 features.
The codebase upon which the samples are based
is 1.4-only and not as cleanly abstracted
as I'd like, especially for a use as a teaching
example. It is, however, well-tested and
production quality.
The example code in the slides has been updated
to the more modern 1.5 syntax but is not a
complete port of the original functionality.
But it can still be informative as an example to
get you started.
I haven't had a chance to neatly package the
code for distribution yet. But it is available
under an Apache 2.0 license. You will need a
copy of the Subversion client (svn). The command
to issue to check out the sources is:
svn co svn://javanio.info/protoplex
If you download the code, please let me know
(email address is below).
If you're interested in helping complete the
port to 1.5 and/or add new features, please
get in touch with me to gain commit access
to the repository.
May 16 - 19, 2006: JavaOne
I spoke at JavaOne 2006,
on May 19th at 10:45am, Session TS-1315. The topic was
How To Build a Scalable, Multiplexed Server Using NIO.
The slides are available on the
JavaOne web site.
This talk is based on experiences I've had
writing server frameworks using NIO on J2SE 1.4. I
updated the code used in the slides to make use
of 1.5 features. Unfortunately, I was not able
to get a working, bundled example app completed
in time for JavaOne.
The codebase upon which the samples are based
is 1.4-only and not as cleanly abstracted
as I'd like, especially for a use as a teaching
example, so I'm not making it freely available
at this time. I intend to finish up and make the
improved code available soon - as open source.
If you want to know when the code is ready,
or maybe help out with it, drop me a line at
the email address below.
Jun 27 - 30, 2005: JavaOne
I did a talk with Jason Hunter at
JavaOne in
San Francisco entitled
XQuery For the Java Geek.
It was about making use of
XQuery from Java.
Mark Logic
(where Jason and I both work) makes a high
performance XML content server based on XQuery.
There was nothing about NIO in this talk, but
we won a Top-20 award, so it must have been pretty good.
The presentation can be found
online here.
December 3-4, 2003: JavaPolis 2003, Antwerp, Belgium
I'll be speaking at
JavaPolis in Antwerp, Belgium
as a part of the Java@University track on December 3rd.
If you plan to attend, please let me know or contact
me at the conference, I'd love to hear from European
readers.
July 7, 2003 - July 11, 2003: OSCON 2003, Portland, Oregon
My proposal for an NIO tutorial at the
O'Reilly Open Source Conference in Portland
was declined (they had one last year and
it didn't fit with the theme this year) but I am
speaking
on the subject of JDO, Wednesday, July 9 at 4:30pm.
Jun 10 - 13, 2003: JavaOne
I plan to attend
JavaOne at
the Moscone Convention Center in San Francisco,
as will several thousand other Java developers. I once
worked across the street from Moscone for a year.
May 14, 2003: Java Metroplex User Group Presentation, Dallas
I will be giving an NIO presentation at
the Java Metroplex User Group
(JavaMUG)
on Wednesday, May 14, 2003 in Dallas, Texas. I lived
in Texas for a total of 12 years - Austin, San Antonio
and Houston - but never in Dallas.
May 15, 2003: Utah JUG Presentation
I will be giving an NIO presentation at
the Utah Java Users group
(UJUG)
on Thursday, May 15, 2003 in Salt Lake City. Salt Lake

several years.
May 20, 2003: San Diego JUG Presentation
I will be giving an NIO presentation at
the San Diego Java Users group
(SDJUG)
on Tuesday, May 20, 2003 in San Diego.
May 8, 2003: Orange County JUG Presentation
I will be giving another NIO presentation at
the Orange County Java User group
(OCJUG)
on Thursday, May 8, 2003 in Irvine on the
UC Irvine campus. I did a presentation there once
before. This one will have new demos and more code
examples. There will also be a short presentation
on Conga.
Apr 15 - Apr 17, 2003: JavaRanch.com Featured Book
Java NIO
will be the featured book on
Java Ranch
the third week of April. Sign up for a chance to
win a free copy of the book. I'll be answering reader's
questions online. Forget your tax woes and come on
along.
Mar 24, 2003 - Mar 28, 2003: Software Development Expo, Santa Clara, California
I will be attending
SDExpo 2003 in
Santa Clara. I'm not speaking (Jason Hunter will
be presenting a session on NIO) but will be there.
Feb 4, 2003: LAJUG Presentation
I will be giving an NIO presentation at
the Los Angeles Java User group
(LAJUG)
on Tuesday, February 4, 2003 in Pasadena at the
offices of Overture. I was originally scheduled for
March but moved up to fill in for someone who
needed to cancel.
Update: The slides, in OpenOffice
Impress format, and example code for this presentation
are online here.
Late 2002: Java NIO now available in a bookstore near you
Java NIO
has made its way through the distribution
chain and is now on the shelves of fine
booksellers worldwide. Look for it whereever
O'Reilly Java books are sold.
Oct 15, 2002: NIO article on
onjava.com.
I wrote a Top Ten article for O'Reilly's
OnJava website. You can jump directly to it by
clicking this graphic.
Sep 24, 2002:Java NIO has been spotted!
I've seen Java NIO on the shelf at MicroCenter near me (Southern California).
Still waiting for it to show up at Barnes & Noble.
Aug 28, 2002: Java NIO has hit the shelves!
I still haven't received my author's copies,
and the major online booksellers (see left sidebar)
don't show it in stock yet,
but I've already received email from people who've
bought it. It should be in your local bookestore
soon, keep an eye out for it.
If you spot it in a bookstore, drop
me a line at
and let me know where you saw it.
June 13, 2002: UC Irvine
I gave a presentation about Java NIO at the
Orange County Java User's group on Thursday, June 13 (www.ocjug.org).
The slideshow, in OpenOffice
Impress format, is online here.
