1. Wunderbar - looks like an interesting kit of hardware and software for IoT applications. They seem to be using MQTT for the message protocol.
2. Comparing bandwidth consumption between MQTT, AMQP and TCP – perfect illustration on why an IoT protocol like MQTT is needed.
3. New MQTT-SN (Sensor Networks) specification published – for really small devices with no TCP
4. Lots of analyst predictions about IoT in 2014 – not a big believer in the `Year of`meme but 2014 is going to be a fun year to be in IoT
