Microsoft Word - P371 EN-Matrix.docx - P371_EN-Matrix.pdf
An ingenious (but obvious once you know it) idea to power RGBW LEDs. Instead of providing a completely separate PWM capable Buck driver for each LED channel you can use one Buck convertor connected to a matrix of Mosfets which selectively switch each LED in or out of the constant current supply. The LT3965 chip contains all the circuitry to do this minus the Buck converter.

Dweb: Decentralised, Real-Time, Interoperable Communication with Matrix - Mozilla Hacks - the Web developer blog
What is Matrix?

Matrix is an open standard for interoperable, decentralised, real-time communication over the Internet. It provides a standard HTTP API for publishing and subscribing to real-time data in specified channels, which means it can be used to power Instant Messaging, VoIP/WebRTC signalling, Internet of Things communication, and anything else that can be expressed as JSON and needs to be transmitted in real-time over HTTP. The most common use of Matrix today is as an Instant Messaging platform.
