Explore how to bend this kernel Swiss army knife to your will.
This talk is not about solving broad, sweeping, Internet of Things-scale issues. This is about approaching Things from the ground up; building interconnected thingies and doodads that will eventually comprise the armies of our future machine overlords.
Internet of Thingies will delve into the physical making of devices which can be used to control systems or collect interesting data. We will look at use cases, making, and using open source software to interact with Thingies.
Snappy Ubuntu Core is the new rendition of Ubuntu, designed from the ground up to power the next generation of IoT devices.

Apache HTrace is a new incubator project which makes it easier to monitor and understand the performance of distributed systems. HTrace aims to provide a truly end-to-end, cluster-wide view of how requests are processed in a production distributed system. I will talk about the architecture of HTrace and how it fits into big data and cloud stacks. I will discuss some of the new features that are on the horizon, and how developers and users can get involved with the HTrace community.
