Servers/Hardware. Here’s a walkthrough to install Arch Linux on VirtualBox. I like the idea of using Docker labels to include a reference to a commit in a version control system as suggested in this article , but as I was thinking about it this morning I had a question. Thinking of virtualizing Linux on Hyper-V?

Although Rowan doesn’t specifically mention it, this command relies on tools like tr , sort , and uniq , so I’m guessing it will only work on OS X/Linux/*BSD systems.

Jeda Networks describes themselves as a “software-defined storage networking” company. Given my previous role at EMC (involved in storage) and my current role at VMware focused on network virtualization (which encompasses SDN), I was quite curious.
