Open Source Enters The World of Atoms — an academic statistical analysis of open design. We indicated that, in open design communities, tangible objects can be developed in very similar fashion to software; one could even say that people treat a design as source code to a physical object and change the object via changing the source.
Why I Like Redis (Simon Willison) — coherent explanation of why Simon likes and uses a particular nosql system. I can run a long running batch job in one Python interpreter (say loading a few million lines of CSV in to a Redis key/value lookup table) and run another interpreter to play with the data that’s already been collected, even as the first process is streaming data in. I can quit and restart my interpreters without losing any data. And because Redis semantics map closely to Python native data types, I don’t have to think for more than a few seconds about how I’m going to represent my data.
Your Movements Speak For Themselves (Jeff Jonas) — Mobile devices in America are generating something like 600 billion geo-spatially tagged transactions per day. Every call, text message, email and data transfer handled by your mobile device creates a transaction with your space-time coordinate (to roughly 60 meters accuracy if there are three cell towers in range), whether you have GPS or not. Got a Blackberry? Every few minutes, it sends a heartbeat, creating a transaction whether you are using the phone or not. If the device is GPS-enabled and you’re using a location-based service your location is accurate to somewhere between 10 and 30 meters. Using Wi-Fi? It is accurate below10 meters. A thought-provoking roundup of the information leakage with modern locative systems. (via TomC on Twitter)
