So a couple of weeks back, I was faced with a chronic productivity drought. I mean I am either at home or at the laboratory and just could not figure out why I could not be productive. It turns out I spend a significant amount of my time on social networking sites (Facebook, Twitter, Google+ and LinkedIn) –I have since started running a series of controlled experiments on myself (results will be published in future publications). I decided to stay away from Facebook, however, most people from back home inbox me with important information –most of whom I need to contact immediately. The huddle though is that I have an Ultra Low Cost Handset (ULCH) that is not GPRS enable –it only has basic SMS and voice GSM capabilities. Continue reading “Facebook Posts via SMS”
I stumbled upon this beauty a couple of days back and thought I should write something about it; it’s basically an Open Office/Libre Office extension. It basically synchronizes documents your are currently working on periodically with googledocs using the googledocs API.
If you’ve lost data before, then you know this is important; I mean I backup all important files on my Laptop on tonnes of servers (I synchronize data with Ubunt One, two servers I have access to at the Department and also on my computer back at the Laboratory).
So here’s how you go about installing the extension; Continue reading “OpenOffice.org2GoogleDocs Extension”
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 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.

So I’ve spent the past couple of weeks trying to familiarize myself with the most common open source digital repository software tools, I’ve using the Parasoft services to test them out. The thing is, I’m going to spend the next 2 years of my life researching on current existing digital libraries software architectures… and eventually (hopefully) prove that a much simpler architecture can work just as well as the current complex software stacks.
Greenstone is a legend! It’s probably because it was one of the first digital repository software package to be implemented. The other reason why it is popular is because it is developed and distributed in corporation with UNESCO.
The Linux distribution basically comes with statically linked binaries (see output below). The installation package also comes bundled with all the necessary tools(ImageMagick with JPEG200 support and Apache web server) required for Greenstone to function appropriately.
