http://www.mygrid.org.uk/dev/blog The developers of myGrid tell of their quest of the code Thu, 14 Aug 2008 12:56:41 +0000 http://backend.userland.com/rss092 en We are currently developing a little REST based service for the storage of RDF.  It uses openAnzo (2.5.1) and Restlet (1.0.5).  All was going well until the client calls disappeared into a black hole.  No responses were coming back from the server, in fact nothing seemed to be arriving there.  ... http://www.mygrid.org.uk/dev/blog/2008/08/hellllloooooooo-where-are-you-restlet/ While debugging some test problems with the T2 code I discovered some issues between OSX and Windows regards file paths and line breaks.  Seems that instead of just inputs.put("fileUrl", LocalworkerTranslator.class.getResource( "/AAC4_HUMAN.sp").getFile()); you have to ensure that the absolute path is correct by doing URI uri = LocalworkerTranslator.class.getResource("/AAC4_HUMAN.sp") .toURI(); File newFile = new File(uri); inputs.put("fileUrl", newFile.getAbsolutePath()); Also, ... http://www.mygrid.org.uk/dev/blog/2008/08/cross-platform-fun/ While developing the Taverna myExperiment plugin we needed some way of launching a browser when clicking on a link.  Launching a browser is fairly easy using Runtime.exec("firefox", URL);   However, how do you know what browsers are installed and what the default one is.  Step forward BrowserLauncher2 (http://browserlaunch2.sourceforge.net/). BrowserLauncher launcher = ... http://www.mygrid.org.uk/dev/blog/2008/07/launch-your-browser/ I'm currently looking into an old bug, TAV-480, that seems to have reappeared. This bug is related to Raven, our classloader system based on Maven that allows us to do plugins and network updates. I'll come with another post about this bug, but first let's do an introduction of Raven. The ... http://www.mygrid.org.uk/dev/blog/2008/04/raven/ Taverna 1.7.1 was released today, including an updated preview of t2, the enactor of Taverna 2.0 scheduled for June 2008. You can download 1.7.1 from SourceForge. This update to Taverna resolves a number of issues with Taverna and the preview of the new t2 enactor. For instance, you should now be able to ... http://www.mygrid.org.uk/dev/blog/2008/04/taverna-1-7-1/ Taverna workflows are full of shims. That's a fact. Shims are the little adapter services, mostly using Beanshells, which convert the outputs of one workflow processor before sending it to the input of another. They are always being re-invented and 90% of the time do the same ... http://www.mygrid.org.uk/dev/blog/2008/04/stand-up-and-be-counted/ Daniel Bayer at University of Lübeck has implemented an ARC Grid plugin for Taverna for submitting job to the grid system ARC, in particular for usage with KnowARC. Bayer, together with Steffen Möller and Hajo N. Krabbenhöft also recently got published in Bioinformatics. The work seems very promising, and in particular ... http://www.mygrid.org.uk/dev/blog/2008/03/arc/ Google Summer of Code (GSoC) is a programme hosted by Google that gives students a chance to work (and paid a scholarship) during the summer 2008 for an open source project. We're happy to announce that OMII-UK (the mother organisation of myGrid) has been accepted as one of GSoC's mentoring organisations. ... http://www.mygrid.org.uk/dev/blog/2008/03/gsoc/ We're hopefully doing our code freeze for Taverna 1.7.1 today, 2008-03-28. There's a few bug fixes, in addition to quite a bit of work on t2. There will also be a drag-and-drop-able, interactive workflow editor, basically you can edit the workflow by connecting lines between the processors. Those of you who ... http://www.mygrid.org.uk/dev/blog/2008/03/codefreeze/ Writing a User Interface is quite often the hardest part of any development job. Everyone likes different look and feel and they seem to take forever to develop. I tend to hand code using Swing (Java's default GUI) because I have not found an interactive GUI designer which ... http://www.mygrid.org.uk/dev/blog/2008/03/future-visions/
