little plans

Last week I updated the littleware project site with a fresh binary code drop - including the first little distro zip bundle download. The little distro unzips into littleware/client, littleware/server, and littleware/webapp folders. The server runs an embedded derby (javadb) database and exports littleware's API services via RMI to standalone and web clients. There are more details on the getting started page.

The littleware/client folder currently just holds the lgo (littleware go) tool - which is a launcher for a small suite of littleware.lgo.LgoCommand derived tools that include a Swing-based GUI for browsing the littleware node tree database, and the command line version of the Voyager to Vufind harvester tool we developed at Auburn.

There's not much useful there really, but it's nice to at least have something to show. The code drop also updates the IVY artifacts and web-start apps hosted by littleware's ivy2maven2 repository as well as the online javadoc and scaladoc API docs.

I was pretty happy with how smoothly the release process went thanks to the ivy build setup. The root build.xml file includes buildAll and buildAndTest rules that a local jenkins continuous integration server executes whenever I push a change to my personal repositories. Everything would have been great if not for the problems that with java 6 update 24 web-start security that plagued me. Ugh!

Anyway, I now need to decide what littleware tasks to tackle next. On the one hand there are several API and infrastructure design flaws that I need to eventually address, but on the other hand it would be good to build out some useful littleware-based applications to demonstrate the systems utility. On a 3rd hand the more application level code I write the more annoying an API-level refactoring will be to propagate, and a 4th hand realizes that application level development is the best way to get ideas for improving an API, and a 5th hand points out that the experience and learning I gain is the main benefit of working on littleware in the first place. I'll probably just continue with the tasks outlined in the current SCRUM sprint, and continue to develop the scala tools in littleware's catalog repository.

The academic library is a terrible market to work for as a library is amazingly cheap, and even if the library had money - it wouldn't want to change anything. A true librarian would turn the clock back to card catalog days in a heart beat. If a librarian ever gets the bomb, then we're all in trouble; he'll blast us back to the stone age smiling ear to ear. These negatives are positives for a loan frickjack that can bundle a suite of open source tools in a cloud-hosted library-in-a-box, and make money charging $200- a month. We'll see what I think next month.
