I have some data I'm playing with that seemed like a good fit for RDF-style interaction, so I thought I'd give ruby-rdf a whirl.
I'm using ruby-rdf, sparql, and rdf-do (backed by do_sqlite3).
I've found that even on a relatively small dataset (just a couple of hundred statements), it takes minutes to execute a SPARQL query like the following:
I hereby claim:

The scenario we were exploring, helping make a music playlist for a road trip, focused on the following:

| {given_balance: 30, when_withdrawing: 30, expected_balance: 0} | |
| ] | |
| scenarios.each_with_index do |scenario, n| | |
| context "given a starting balance of #{scenario[:given_balance]} (scenario #{n})" do | |
| it "should have #{scenario[:expected_balance]} left after withdrawing #{scenario[:when_withdrawing]}" | |

A quick and unofficial UQM package for the fourth and final Precursors album. I'm sure someone working on this already -- someone with better knowledge and experience than me -- but I put this together to gain a bit of experience.
Hopefully you'll find it useful too (at least until the official package comes out).
How do I install it?
| ### Setting up a Mac OS X 10.7 "Lion" machine for Python development | |
| # for Buckets | |
| ## get a per-user-safe distutils ("easy_install") | |
| # strictly speaking you can use the built-in one (as long as you sudo) | |
| # but I prefer to be sudo-free and keep thing self-contained | |
| # so that I don't tangle the system up by accident | |
| # | |
| # use Distribute's alternative easy_install instead of sudo-ing the Mac-provided easy_install |
