This is a tutorial on how to implement a programming language. If you ever wrote an interpreter or a compiler, then there is probably nothing new for you here. But, if you're using regexps to “parse” anything that looks like a programming language, then please read at least the section on parsing . Let's write less…
This article describes a self-contained computer with its own display and keyboard interface, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as LEDs and push-buttons via the I/O pins, read the analogue inputs, and operate external devices via the…
Ok, I lied, there’s no weird trick. However, you can easily reduce a Go binary size by more than 6 times with some flags and common tools.
One thing that works well in practice in cases where you really don’t want to process single bytes at a time is to use a union for going from one type to another. Granted, writing one member of a union and reading from a different one also isn’t allowed per the standard, but every compiler I’ve come across allows it…

ASDF , the de facto standard build system for Common Lisp, has been vastly improved between 2009 and 2014. These and other improvements finally bring Common Lisp up to par with "scripting languages" in terms of ease of writing and deploying portable code that can access and "glue" together functionality from the…
In this blogpost we'll see how Erlang's Syntax already appeared on TAOCP years before the language was even created.
For the past few years I’ve followed the evolution of Rust with interest. Rust is a new systems programming language (like C or C++) with greater emphasis on...
This site will be the main location for information about the LLVM backend for Scala that is under development by Geoff Reedy.
A few months ago I gave a presentation on my philosophy for error handling . In the talk I introduced a small errors package designed to support the ideas presented in the talk.
One of the things I love about Lisp is that it gives you the ability to change and mold the syntax of the language to what you need. In this post I want to look at the evolution of a little macro I've been playing around with for a while now.

A year ago I wrote an article trying to round up new languages since year 2000 and what I think of them by just… glancing at them, or otherwise playing with them. I ended up sifting out the 4 m…
Apple has been actively evangelizing the use of Swift since it was announced at WWDC in 2014. In the Platforms State of the Union, Andreas…
“If you don’t know how compilers work, then you don’t know how computers work. If you’re not 100% sure whether you know how compilers work, then you don’t know how they work.” — Steve Yegge There you have it. Think about it. It doesn’t really matter …

The story of a new programming language
Some time later, I came across Iavor’s "jokes" page, including a funny bit called “ The Evolution of a Programmer ” in which the traditional imperative "Hello, world" program is developed through several variations, from simple beginnings to a ridiculously complex extreme. A moment’s thought turned up the factorial…
