We wrote a Brainfuck compiler back in April . That one developed a simple architecture to support multiple backends. Today, I want to write a new Brainfuck compiler. One that can only run on a single system, OpenBSD /amd64. And one that is as small as I can possibly make it. I broke into the sub-256 bytes club with my…

Apache Spark 1.4 introduces SparkR, new DataFrame features, ML pipelines, and enhanced visualization and monitoring tools for better production debugging.
At this point in my career, I’ve worked on at least three projects where performance was a defining characteristic: Livegrep, Taktician, and Sorbet (I discussed sorbet in particular last time, and livegrep in an earlier post). I’ve also done a lot of other performance work on the tools I use, some of which ended up on…
Recently, I’ve been working on a music app that needs to get a musical sequence (like a melody) from the server to the client. To do this, we use a format called ABC. (You can read about how ABC music notation works here .) We chose ABC because it’s more readable than MIDI, it’s pretty concise, and it’s a standard, so…
Over the years, mathematicians, logicians and computer scientists have developed various calculi. If you have a background in computer science, you’ve likely heard of the lambda calculus, a m…
Welcome! This is a series of blog posts that shows you how to build a text editor in Rust.
Prolog is a language that excels at defining and exploring relationships. Let’s take advantage of that and use Prolog to explore a few of the myriad of relationships that exist between chords and the guitar’s fretboard.
This complete guide explains all about Linux system calls with sample codes and results.

When an srid is not specified, it defaults to using 4326, Earth WGS 84 long lat.

Earlier this month I wrote about how Windows 10 holds a lock during too much of process destruction, which both serializes this task and causes mouse-cursor hitches and UI hangs (because the same l…
A summary of the work done so far on getting MicroPython to work on the BBC micro:bit device for children.
Zngur (/zængɑr/) is a C++/Rust interop tool. It tries to expose arbitrary Rust types, methods, and functions while preserving their semantics and ergonomics as much as possible. Using Zngur, you can use arbitrary Rust crates in your C++ code as easily as using them in normal Rust code, and you can write idiomatic…
“Summing ASCII Encoded Integers on Haswell at the Speed of memcpy” turned out more popular than I expected, which inspired me to take on another challenge on HighLoad: Counting uint8s . I’m currently only #13 on the leaderboard, ~7% behind #1, but I have already learned some interesting things. In this post I’ll…
