North Korea is generally thought to be the most isolated country on the planet. There is very little uncontrolled communication into and out of North Korea, and most countries have few or no ties to them. But North Korea, like all countries, needs computers, and those computers need an operating system. Enter “Red Star OS,” a Linux-based operating system used by North Korea, and written by their developers. In this talk, Florian Grunow and Niklaus Schiess look through a copy of Red Star OS, examining its features, including what makes it special (and different) from other Linux distributions.
When we program on a Unix machine, we often use a terminal window. But what does a terminal program do? What is it trying to emulate, what features does it support, and how can you take advantage of it when you’re working? Why does it work the way it does, anyway? And using a bit of Python and understanding of what’s happening behind the scenes, what sorts of interesting things can we do? In this talk, Thomas Ballinger answers al of these questions, mixing his descriptions with extensive live-coding demos.
Docker provides you with containers, which are sort of (but not quite) virtual machines. Why has Docker become so exciting in such a short period of time? What can you do with it? In this talk by Brian Goff, we learn what Docker is — and also what it can do for you, beyond what you might expect. If you’re new to Docker, or curious to know how it can help to improve your development or deployment, this talk should be of interest.
Firefox is a well-known open-source Web browser from the Mozilla Foundation. FirefoxOS is a new open-source mobile operating system, designed to comply with Web standards and be as open as possible. In this talk, Aimee Marie Forsstrom introduces FirefoxOS, describes the different parts of this architecture, and shows how it is similar to (and different from) Android.
Bo Jeanes demonstrates some absolutely amazing things that you can do with ssh. If you use ssh, then you will likely learn a bunch of new tricks from watching this talk. If nothing else, seeing text-based slides is itself worthwhile.
