A detailed tutorial on DDR4 SDRAM Initialization, Training and Calibration. Exploring topics such as Read/Write Training, ZQ Calibration, Vref Training, Read Centering, Write Centering, Write Leveling and Periodic Calibration.
This article documents Hacking Team’s third-party acquisition of zero-day (0day) vulnerabilities and exploits. The recent compromise of Hacking Team’s email archive offers one of the first public case studies of the market for 0days. Because of its secretive nature, this market has been the source of endless debates…
“C++11 feels like a new language.” – Bjarne Stroustrup The C++11 standard offers many useful new features. This page focuses specifically and only on those features that make C++11 really feel like…
Ursula K. Le Guin on the presence of technology in her work
A groundbreaking study from Just Facts has found that the poorest 20% of Americas consume more goods and services than the averages for most of the world�s richest nations.
If you enjoy this article, I have published a book explaining the internals of Git through implementation: Building Git .
Almost a year ago now, Jack Diederich gave a talk entitled “Stop Writing Classes“, in which he implores Python programmers to stop creating classes just for the hell of it, and specifically calls out the common pattern of a class with only a constructor/initializer and a single method—which should, of course, just be…
Tech is entering a period of inequality where the big winners lift the sector as a whole even as smaller companies suffer. The best example is Facebook, Google, and digital advertising.
Oftentimes when I am conversing about the design of Rust with other users - as on RFCs or the internals forum - I witness a peculiar remark about “explicitness.” It usually goes something like this: I do not like Feature Design X because it is too implicit. Magic is okay in Other Language Y, but Rust is supposed to be…
After working through “the book” on the Rust programming language and getting started with the first non-trivial, real-world application I found myself faced with a question I didn’t yet feel well-equipped to handle: “How should you structure error handling in a mature rust application?”
Most of my systems are microcomputers (and commensurately sized), though I do have some moderately larger beasts: you've met homer , my 1987...
A draft design document describing lightweight userland cooperative threads for SBCL.
I really wanted to make this article short … but I failed miserably. At least I tried to organize it well so one may get back to it after ‘some’ reading because its not a short le…
On Friday, MIT Technology Review published an article on the cryptocurrency IOTA. However, we at the Media Lab have issues with the story
New study suggests that plasma exchange could be the key to unlocking the body’s regenerative capacities

Even if you can’t stop Flock’s use entirely, you can still help protect civil liberties in your community.
Editor’s note: For this blog entry I welcome my friend and colleague Gerben Stavengaas a guest author.
We present a prototype of a programming system called Shadama. Shadama is designed for writing programs that create, control and visualize large numbers of objects. The basic execution model follows the tradition of StarLogo and its "turtles and patches" abstraction. Turtles, Termites, and Traffic Jams: Explorations…
I read a fantastic article in Nature magazine (vol 459, pp931-939 (18 June 2009)) that summarizes not only the current state of novel H1N1 (aka Swine Flu) understanding, but also a compares H1N1 against other flu strains. In particular, it discusses in-depth how the pathogenic components — i.e., the stuff that kills…
Type inference is a major feature of several programming languages, most notably languages from the ML family like Haskell. In this post I want to provide a brief overview of type inference, along with a simple Python implementation for a toy ML-like language.
Pattern matching and exhaustive switches come together to enable functional style data models that blend seamlessly with Dart’s…
Karl Seguin's Blog - A mix of coding and creative writing
At Open Whisper Systems, we’re working to both advance the state of the art for secure communication and also reduce the friction required for ordinary people to make use of it. We want everyone to have access to advanced secure communication methods that are as easy and reliable to use as makin...
