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?

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.
