The Science of Insecurity

A shout to Meredith Patterson's talk, "The Science of Insecurity" at the Chaos Communication's Congress. I cannot say I truly understand what she is saying in this Youtube video, but this seems to be something to keep in mind. In my understanding, this seems to suggest avoiding anything but regular expressions to avoid weird machines (unexpected behavior due to an attacker).

Turtle Files and Trying to set up

So apparently turtle files are useful for configuration. Such files are used in Apache Fuseki as well as Here is's, and here is Joseki's (what was before Fuseki).

What's with this madness? Well, I'm trying to get to search for .rdf files on my local machine. Szymon Danielczyk, the maintainer for mentioned that sparql search and lookup providers needed to be configured to find them (see his post in Google groups here).

I'm guessing that I need something else besides Fuseki (if it indeed works with, such as a regular search engine. Rather arbitrarily, I searched for Apache search engines on Google and I found Apache Solr.

I'm trying to follow the design of Sindice found in the developer section since Sindice is part of I also found the metadata extractions link, and the Sindice API link particularly interesting. I may have to check out the paper on titled " Live views on the Web of Data" found at: In light of being unsure, I may also check out the SPARQL tutorial as well as SOH - SPARQL over HTTP for Apache Jena. This should be a learning experience!

Chat on SWIG

Thanks to a chat that I had online, I am now aware of OpenCyc, Falcons, and UMBEL. Actually, I may have heard of UMBEL before. In any case, UMBEL and OpenCyc are very broad ontologies. OpenCyc is by far the larger one. Falcons is a semantic web search engine. Thanks to the chat, I also found that the goodrelations ontology is useful when someone owns something. In addition, I also found that the UMBEL ontology describes charitable donations.

Online I found an article titled, "FOAF & SSL: creating a global decentralised authentication protocol" at: Or equivalently:

I really like Rhizomik. It is a handy tool for visualizing ontologies on line.
