How To

Total Request Live!

I've spent some time these past weeks trying to figure out a good way to get some extra packages into our online package repository.  After discussing with Marcin and Ken, we finally decided that we'd have our own extra overlay and buildbot slave that would build a meta-package and its dependant packages.What does this mean?  It means that we can bring in packages from OE, build them, and host the binaries (and relevant package-related metadata)...

BUG + MySQL + openJDK-cacao

Developing database applications for the Bug Platform can be challenging, mostly because phoneME doesn't support JDBC. A viable solution to this problem might be installing a different JVM, one which supports JDBC, like cacao or openJDK. However, like almost any solution in the computer world, nothing comes for free; by switching phoneME for cacao or openJDK you'll sacrifice speed in order to gain more functionalities (see kschultz JVM Comparison post). Recently, I wrote an app...

Java Coding Style

I used to work at a place that had a big long document on company-wide coding conventions.  Some of the conventions were arbitrary and ugly, like prefixing all method parameters with a lower-case p (I came to realize that all of the variable prefixing made the code less readable, not more).  We also had rules on where to write the curly braces, where to declare variables, how to name classes, etc. Some of it was...

BugMail (Installing Postfix in your Bug)

Overview  With so many free mail services out there why would you like to have your own. Well, I can think in a few reasons: probably you want to create a portable e-mail both, or simply you want to play around with your bug. Another good reason would be that phoneME doesn't support https which it's need it if you want to use any free mail service (yahoo, gmail, etc), and having postfix is a...

JFace EditingSupport for Custom Tables

Stan Lee in Spider Man taught us that, "With great power there must also come -- great responsibility!"  I think about that quote when working on Eclipse plug-ins, only it changes in my head to read, "With great power there must also come -- great complexity!"  Eclipse provides the building blocks to do wonderfully powerful things, but to wade into plug-in development is to wade into all sorts of complexity.  My most recent responsibility/complexity was...

BeagleBoard, Java, OSGi, and Benchmarking

The BeagleBoard is a sweet little single board computer from Texas Instruments, based on the OMAP 3530 processor. It features audio in and out, S-Video and DVI out, USB, RS-232, and an SD card (though surprisingly it lacks an Ethernet port or wifi onboard, so you must buy some extra parts if you want internet access). It has solid community support and well documented instructions for building an image with OpenEmbedded. The best place to...

N-Body Simulations: Fun Fun Fun!

Several months back and M3DD, in an after hours session in a rather empty and dark cafateria on Sun's San Jose campus, I saw a demo of Kepler's Orrery on a laptop by the developer, Simran Gleason.  I was immediatelly intriguged and, when discovering it was available on the iPhone, picked it up.  Physics simulations in general have always interested me and the way that music was incorporated into the simulation was really stunning. Simran's...
