Meuchian Grouping Method – XSLT 1.0

I have a huge XML document that makes up metadata for bushman drawings that were compiled in the late 19th centuary and recently digitised. I am trying to generate a view of part of that information, but I need to rearrange the structure of some XML elements. Oh, and YES! I do know that this can potentially be done seamlessly in XSLT 2.0 [1], but I want to generalise my solution and not restrict myself to processing my documents with a particular xslt processor –Saxon [2] is the only xslt processor known to be compatible with xslt 2.0.

SAICSIT 2011 Postgraduate Symposium

I am just settling down, after attending this year’s three(3) day long (October 3 – October 5,  2011) SAICSIT conference. So I submitted a poster abstract –towards the end of July, 2011– for the Masters and Doctoral Symposium. It was acceptable and I was accorded the opportunity to give a 20 minute long presentation and also showcase my work through an A1 poster. Continue reading “SAICSIT 2011 Postgraduate Symposium”

Ubuntu Past Group Membership

I was in the process of installing Virtualbox day before yesterday (September 20, 2011); needed to add myself to the vboxusers group, but accidentally erased my group membership on Ubuntu –I feel retarded right now. It was a silly mistake really, I accidentally left out the “-a” (append) switch when I was trying to add myself to the vboxusers group.

A tail on /var/log/syslog file was not very helpful. Continue reading “Ubuntu Past Group Membership”

apt-get update – W: Failed to fetch http://archive.canonical

I have a confession to make; I am obsessed with problem solving….. I know you’re probably looking forward to seeing how I solved the problem, but I figured you might be interested in some background information before we proceed. I was in the process of installing a digital repository tool (DSpace) and it so happens that Oracle Java JDK 6+ is one of the prerequisite software required; the result of not installing Oracle’s JDK is below 🙁 Continue reading “apt-get update – W: Failed to fetch http://archive.canonical”

DSpace Installation on Ubuntu 10.10

Dspace is probably one of the most widely used digital repository software package. It has evolved into a complex software stack over the past couple of years; as of this writing (April 2011), the latest version is 1.7.1 with new features that include DSpace discovery, Mirage XMLUI theme, a curation administration UI and most importantly, the AIP Backup& Restore process.

I believe I mentioned in one of my previous posts that my research is focused arguing that the complex software stacks currently employed in most of the digital repositories tools can in actual fact be abstracted; in other words, make the overall architecture simple.  Not quite sure how to interpret the statement below (it’s on the Dspace about page)

It is free and easy to install “out of the box” and completely customizable to fit the needs of any organization.

I beg to differ, it’s not “easy to install” and it sure as hell not “out of the box”….. I had to install a motherload of components; and the installation manual makes reference to specific software versions of the same components. And who ever came up with the idea of integrating it with Oracle? We all know the software is not free; well the free express edition has CPU(2 processor limit), RAM (no more than 2GB) and above all space(10g XE has a 4GGB cap….. the newer 11gR2 XE version however has a 11GB cap, but as of this writing, it’s still a beta version) limitations.
