4Store with Snorql on Raspberry Pi

Problem I need to access triple-store data for a work thing, but the data I have to test with isn't in their (sesame) triple store yet. There are RDF files, though. Solution Install 4Store on a pi (I had one with a default Raspbian running because it's the mumble server). sudo apt-get install 4store ...then I set up the 4store with instructions from here : sudo 4s-backend-setup saws sudo 4s-backend saws 4s-httpd saws then import the RDF files with a convoluted command: curl --verbose --header 'Content-type: application/rdf+xml' --upload-file MSH_Thales_Trans.rdf --url 'http://localhost:8080/data/http%3A%2F%2Fwww.purl.org%2Fsaws%2Fontology%23' (for each file - the url is the saws url encoded, the .rdf bit was done for each file). Then fix the RDF, because rapper rejects it all. To validate the RDF I used this: http://www.rdfabout.com/demo/validator/ Okay, now I can see things on the pi: http:// <pi ip address...

Mumble and Murmur on Raspberry Pi

Problem:  Skype kind of sucks for games night things. Potential Solution: People have suggested ventrilo, etc., but murmur (the mumble server) will run on a raspberry pi. As I have a few of them, I reimaged an SD card with the newest raspbian, then followed the instructions here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=36&t=8615 If I put it in the DMZ, hopefully people from outside Nerdvana should be able to connect to it. It supports positional audio for games - I wonder if I could make a plugin that would just allow you to set your position, so that we could be around a virtual table with positional audio? ...Looks like there is: Mumble comes with a plugin for manually positioning audio. http://mumble.sourceforge.net/Games#Manual_Positional_Audio_Plugin
