Sex toy tells manufacturer when you’re using it
the "We-Vibe 4 Plus" phones home with telemetry data including temperature, and when the user "changes the vibration level". wtf

Introducing Atlas: Netflix's Primary Telemetry Platform
This sounds really excellent -- the dimensionality problem it deals with is a familiar one, particularly with red/black deployments, autoscaling, and so on creating trees of metrics when new transient servers appear and disappear. Looking forward to Netflix open sourcing enough to make it usable for outsiders

Low Overhead Method Profiling with Java Mission Control now enabled in the most recent HotSpot JVM release
Built into the HotSpot JVM [in JDK version 7u40] is something called the Java Flight Recorder. It records a lot of information about/from the JVM runtime, and can be thought of as similar to the Data Flight Recorders you find in modern airplanes. You normally use the Flight Recorder to find out what was happening in your JVM when something went wrong, but it is also a pretty awesome tool for production time profiling. Since Mission Control (using the default templates) normally don’t cause more than a per cent overhead, you can use it on your production server.

I'm intrigued by the idea of always-on profiling in production. This could be cool.
