Aeotec Z-Wave Z-Stick Gen 5 UART protocol

Z-Stick Serial API

The Z-Stick does bi-directional communication over a UART. The connection speed is 115200, '8N1'. There are "requests" and "responses". The client software can make requests to the Z-Stick, and it will send responses. But it seems the Z-Stick can make requests of the client software too. I have yet to figure out the requests the Z-Stick sends to the client software.

talk given by John Ousterhout about sustaining relationships

"Scar Tissues Make Relationships Wear Out"

04/26/2103. From a lecture by Professor John Ousterhout at Stanford, class CS142.

This is my most touchy-feely thought for the weekend. Here’s the basic idea: It’s really hard to build relationships that last for a long time. If you haven’t discovered this, you will discover this sooner or later. And it's hard both for personal relationships and for business relationships. And to me, it's pretty amazing that two people can stay married for 25 years without killing each other.

[Laughter]

> But honestly, most professional relationships don't last anywhere near that long. The best bands always seem to break up after 2 or 3 years. And business partnerships fall apart, and there's all these problems in these relationships that just don't last. So, why is that? Well, in my view, it’s relationships don't fail because there some single catastrophic event to destroy them, although often there is a single catastrophic event around the the end of the relation
