Low-Latency Live Streaming for your Desktop using ffmpeg and netcat:

Preamble:

In this post I will explore how to stream a video and audio capture from one computer to another using ffmpeg and netcat, with a latency below 100ms, which is good enough for presentations and general purpose remote display tasks on a local network.

The problem:

Streaming low-latency live content is quite hard, because most software-based video codecs are designed to achieve the best compression and not best latency. This makes sense, because most movies are encoded once and decoded often, so it is a good trade-off to use more time for the encoding than the decoding.

So, You Want to be a Systems Engineer

Systems Engineering (also known as Infrastructure Engineering, Operations Engineering, or DevOps) is a challenging but rewarding career path. Because Systems Engineering draws from a wide variety of smaller topics, it can be hard to know where to start and in what order to begin. This resource is intended to give you a sketch of some of the learning-paths that that can lead you to a career in Systems Engineering.

What do I need to know?

To start, let's examine a high-level list of topics that established systems engineers should have knowledge of. In each of these topics, the level of depth required to get started as a systems engineer may vary, but it's good to have a general breadth of knowledge on all of these topics.

These lists are not exhaustive, rather a good starting point to gain general knowledge.

Javascript Cryptography Considered Harmful

WHAT DO YOU MEAN, "JAVASCRIPT CRYPTOGRAPHY"?

We mean attempts to implement security features in browsers using cryptographic algoritms implemented in whole or in part in Javascript.

You may now be asking yourself, "What about Node.js? What about non-browser Javascript?". Non-browser Javascript cryptography is perilous, but not doomed. For the rest of this document, we're referring to browser Javascript when we discuss Javascript cryptography.
