I've got Eurosong fever, Ted - I can't describe how much I love this data analysis, big thanks to Anthony Goldbloom for pointing me to it. It's both a wonderful example of the insights you can obtain into the real world from surprising data sets, and an excuse to enjoy the delights of Ruslana and Verka Seduchka.
Setun - An experimental computer from Russian in the 60's, built on ternary logic instead of binary (here's a Wikipedia summary). It's not that long ago that we were arguing over things that we take for granted now, I wonder if we'll have to revisit those assumptions as we keep innovating?
Green Marl - On the subject of revisiting assumptions, MapReduce isn't the only way to run distributed algorithms, and I've been trying to wrap my head around projects like this graph analysis framework from the Stanford Pervasive Parallel Computing team.
The role of intuition in business - Metrics are like a compass leading you to a local maximum, the human part of all our jobs is knowing when to make a big leap to get to a whole new surface.
Cassandra compression is like getting more servers for free! - I'm itching to try this on our cluster, once I upgrade to a newer Cassandra version.
