This SDK allows you to control BlinkStick devices connected to your computer via Ruby. It's available for Linux and Mac OSX and is an official release.
BlinkStick is a smart LED controller with integrated USB firmware. It plugs into your computer and allows control the color of individually addressable or single color LEDs and LED strips and wide range programming language implementations give you the power to control the LEDs without the need to program a microcontroller.
It acts as a HID (Human Interface Device) and does not need any additional drivers. It uses ATTiny85 microcontroller with V-USB firmware.
Last week MQTT (Message Queuing Telemetry Transport) provided developers with a signal that it may be emerging as the de facto protocol for the IoT. This validation comes in the light of positive MQTT Interoperability Test Day results that were published by the host of the event: The Eclipse Foundation and the Eclipse IoT Working Group.
It may take some getting used to, but with more control over applications, developers will have to assume a lot more responsibility for their performance. At the Node Summit yesterday, F5 Networks announced that it is leveraging technology gained via its acquisition of LineRate Systems to allow developers to customize Web traffic via an API created using the Node.js framework.
