This week, I’ve been working on an application that sets up IPsec connections. PF_KEYv2 is the standard interface for configuring IPsec. PF_KEYv2 is widely-available; even systems with more advanced IPsec stacks (like XFRM on Linux) provide a PF_KEYv2-compatible wrapper. I want my application to work on OS X and…
A wifi-deploying tank robot controlled with JavaScript/Node.js.
Attached Code: https://github.com/iainkfraser/cache_transpose Before we begin, the underlined words are briefly described in the gloss...
A follow-up on a previous story, in which we identify another problem, and perhaps confirm a theory through a theorem.
An extensively updated and expanded version of the best-selling first edition. Now covers recent and more advanced features of Haskell.
There is an increasing number of libraries which are described as high performance and have benchmarks to back that claim up. Here is a sele...
Little Lisp is an interpreter that supports function invocation, lambdas, lets, ifs, numbers, strings, a few library functions, and lists. I wrote it for a l...
In this tutorial, you are going to learn the basics of Vue.js. While we learn, we are going to build a Todo app that will help us to put in practice what we learn.
One of the more interesting design challenges with go-github (and subsequently the one that results in the most questions) is the use of pointers for most all of the fields in our structs that are marshaled and passed to the GitHub API. After a fair amount of trial and error, I settled on the approach that I’m going…
Capacitor vendors don't want you to know this! Save money on capacitors by spending more on other components
In Chapter 1 , I asserted that the grammar of Lisp is uniform: every expression is a list, beginning with a verb, and followed by some arguments. Evaluation proceeds from left to right, and every element of the list must be evaluated before evaluating the list itself. Yet we just saw, at the end of Sequences , an…
Resurrecting an old tradition of this blog, let’s take a simple problem, go over a way too long list of alternative solutions, and evaluate their merits. Our simple problem is this: we want t…
Combobulate is a package that adds advanced structured editing and movement to many programming modes in Emacs. Here's how it works, and how it can enrich your editing experience in Emacs.
When learning a new programming language, I tend to write two things with it: a language interpreter (usually a FORTH-like language or Brainfuck if I'm feeling lazy), and a HTTP server. Sometimes, just as a challenge or a way to quench my boredom, I do this even though I've been working with a particular language for…
Map any 3D point on or above a triangle-subdivided sphere to a triangle index in constant time, without recursion, table lookups or complicated branching logic.
Emacs provides four useful status bars (mode-line, header-line, tab-bar, and tab-line), but each imposes different, inconsistent limits on multi-line layout, al...
meshoptimizer implements several geometry compression algorithms that are designed to take advantage of redundancies common in mesh data and decompress quickly - targeting many gigabytes per second in decoding throughput. One of them, index decoder, has seen a significant and unexpected variance in performance across…
Thinking about thinking when coding, and the differences in what we see in our minds eye
As all developers, I’ve been using git since the dawn of time, since its commands were an inscrutable jumble of ill-fitting incantations, and it has remained this way until today. Needless to say, I just don’t get git. I never got it, even though I’ve read a bunch of stuff on how it represents things internally. I’ve…
