In the current tech scene, many developers use so-called Container-based virtualization such as Docker or LXC.
The speaker will talk about Linux container technologies and his tools. He develops haconiwa (https://github.com/haconiwa/haconiwa), a tool helping developers combine container features such as cgroup, namespaces and capabilities which they want to use.
The speaker has about 2 years experiences on Docker (in-house CI basis) and LXC (PaaS service). The talk has background of (some) issues found in these experiences, and includes why he's creating a new container in Ruby and why he switched to *m*ruby.
