Jazoon Presentation on Distributed Client/Server Persistence

I’ve presented at this year’s Jazoon conference on Hölchoko, a framework for distributing the persistence of your JPA domain models to multiple clients. While the project itself is not where I would have expected it to be by now, I’ve finished enough of the demos to show what the idea is all about.
I’ve uploaded the presentation here. I know the demo still has the encumbrance of IntelliJ Idea forms for parts of the UI. I hope to get enough time to remove these very soon.

I plan on closing the remain tickets and release version 0.9.1 somewhere next week. I know the type system abstraction still requires quite some work. Finishing the remote filter for sending entities back to the server is just a matter of back porting from the in production systems and developing the dynamic proxy I show in the presentation. Code cleanup is still an issue and so is JavaDoc! HMVC is pretty there already…

Hudson continuous build full screen monitoring

I’ve just quickly hacked a fullscreen monitor for our continuous integration server at work. As for my personal projects, we use Hudson, which has a nice restful xml API.This small utility asks for the url of your Hudson server and retrieves all the jobs and their status. You can also provide the url to a view, would you want to only partially monitor your jobs (such as only the continuous integration builds, ignoring nightly builds, or the other way around).

HudsonMonitor Main screen

When in full screen mode, the tool will poll the server every 15 seconds for job updates and render a fully red, yellow or blue (and yes, I kept the blue!) screen displaying the worse status of your currently monitored jobs. Should the screen not be blue (all monitored builds stable), it will also display the list of unstable or broken builds.

Everything is pretty much hacked together, with way too many inner classes (lazy me!). This is what I call a “one movie hack”, as I quickly wrote this with the computer on my lap next to my wife while we were watching a movie… or at least she was! Besides, it uses the IntelliJ Idea’s layout manager for the main screen. I’ll try to clean this all up. In the meantime the code is available through a:

svn co http://www.codespot.net/svn/repos/HudsonMonitor/trunk HudsonMonitor

and the executable jar is available here.
