Let's build our own Internet-of-Things

presented by Johannes Ernst

The internet of things today is entirely dominated by vendor silos, from locked-down hardware and firmware to opaque communication protocols, big privacy-invading data stores in the cloud under vendor control, and only very selective APIs, usually cloud-only. Can we do better?

In this BoF, we'll have an open discussion about IoT projects and products that follow the Linux spirit of openness ...

Computers are Broken (and we're all going to die)

presented by Bryan Lunduke

Let's face it, the future is here... and all of our computers are broken. Software is slow and buggy. Systems are only supported for a few years (at most). Everything is reliant on an active Internet connection just to function at a basic level. Even our CPUs, themselves, are inherently insecure (by design). It's utter chaos. In other words: We're all doomed.

Almost eight in ten small business owners (79 percent) do not have a plan for incident response to limit the effects of a data security event.
