This text is designed to accompany your study of introductory digital signal processing. 1 It’s an eccentric piece of not-so-rigorous literature with a preoccupation for explaining things using interactive visualizations, animations and sound. 2 My goal is to explain the Discrete Fourier Transform using a miniature…
Preamble Destroying the Earth is harder than you may have been led to believe. You've seen the action movies where the bad guy threatens to destroy the Earth. You've heard people on the news claiming that the next nuclear war or cutting down rainforests or persisting in releasing...
The way I thought you used a dictionary was that you looked up words you've never heard of, or whose sense you're unsure of. You would never look up an ordinary word -- like example , or sport , or magic -- because all you'll learn is what it means, and that you already know.
As part of the research for my book , I came across an algorithm called Redlock on the Redis website. The algorithm claims to implement fault-tolerant distributed locks (or rather, leases [1]) on top of Redis, and the page asks for feedback from people who are into distributed systems. The algorithm instinctively set…
When people click a URL and see that it’s a Medium site, their reaction should be “Oh, good, a Medium site — this will be nice to read.” Right now it’s gotten to the point where when people realize an article is on Medium, they think, “Oh, crap, it’s on Medium.”
There's an old joke that computer science is a lie, because its not really about computers, and its not really a science. Funny joke. Everyone laughs, then someone says "Yeah but it sort of is about computers though, isn't it?". Feet shuffle awkwardly. Someone clears their throat and before you
SpaceX's new raptor engine is a methane fueled full flow staged combustion cycle engine and its so hard to develop, no engine like this has ever flown before!Now this topic can be really intimidating so in order to bring the Raptor engine into context, we’re going to do an overview of a few common types of rocket…

I feel for Google – Steve Jobs threatened to sue me, too. In 2003, after I unveiled a prototype Linux desktop called Project Looking Glass*, Steve called my office to let me know the graphica…
I’m going to tell you about how I took a job building software to kill people. But don’t get distracted by that; I didn’t know at the time.
You don't have to be at a party to see this phenomenon in action, but there's a curious thing I regularly see at parties in social circles where people value intelligence and cleverness without similarly valuing on-the-ground knowledge or intellectual rigor. People often discuss the standard trendy topics (some recent…

An in-depth exploration of a new class of expressive, performant, and intuitive CRDTs, together with macOS and iOS sample code.
Quick summary of my recommendations on compare-by-hash: If you are using compare-by-hash to generate addresses for data that can be supplied by malicious users, you should have a plan to migrate to a new hash every few years. For example, BitTorrent falls into this category, but rsync doesn't. Keep in mind that new…
Every now and then, I stumble onto some algorithm or idea that’s so clever and such a perfect solution to a problem that I feel like I got smarter or gained a new superpower just by learning it. Heaps were one, just about the only thing I got out of my truncated CS education. I recently stumbled onto another: Pratt or…
One year and a half ago, an important part of FFmpeg developers decided to change the way the project was managed. This led to some kind of takeover , mainly to get rid of the old maintainer dictatorship, but also to change development methods, redefine objectives, etc. Then, for various reasons I will quickly…
There certainly is one thing that most Linux users don't realize about their Linux systems... this is the lack of GUI-level isolation, and ...
This is the text version of a talk I gave on October 1, 2015, at the Strata+Hadoop World conference in New York City. The video version is here (20 mins).
Rich countries consume much higher quantities via higher intensity/tech. It's NOT high and rising: wages, profits, administration, encounters, etc. Income well explains American behavior here too.
