Elk [Scheme] is an implementation of the Scheme programming language. In contrast to existing, stand-alone Scheme systems Elk has been designed specifically as an embeddable, reusable extension language subsystem for applications written in C or C++.
When I was first learning about Functional Programming and Scheme, the idea that order-of-execution didn’t matter in purely functional programs, was “strange to me”, to put it nicely. When I first read about Scheme’s begin form, for example, I remember feeling satisfied that Scheme wasn’t totally insane as it had at least some way [...]
‘LAMBDA: The Ultimate GOTO’ (found here) is a paper that was written in 1977 by Guy Steele. It is fun to read, informative, and accessible to a wide-variety of programmers and interest levels. Here are some interesting bits about the paper (I will leave the detail to the paper, no sense in trying to re-state [...]
‘LAMBDA: The Ultimate Imperative’ (found here) is a paper that was written in 1976 by Guy Steele and Gerry Sussman. It is fun to read, informative, and accessible to a wide-variety of programmers and interest levels. Here are some interesting bits about the paper (I will leave the detail to the paper, no sense in [...]
The Lambda Papers are a series of seminal works on programming language design and implementation written by Guy Steele and Gerry Sussman.
You may have heard about them because of the very popular Lambda the Ultimate website, or maybe you just heard about them because you are studying Scheme, or are a student of programming history. [...]
In the comp.lang.lisp post [Slow Loop (alternatives in lisp?)] Francogrex asked how to implement pivot table functionality without it taking forever using inner loops. Folks posted clearly faster solutions along with good advice. By the way, taking forever means 12 hours for inputs of 1 million data points.
I wondered how you might lead someone down [...]

Scheme-OSA stands for Open Scripting Architecture. It provides an abstract interface for applications to compile, execute, and manipulate scripts without needing to know the details of the particular scripting language. Scheme-OSA bridge furnishes a Scheme user with a means of accessing the OS X multimedia and other resources from Apple and the third parties - [...]
In this post on the PLT discussion list I sleepily wondered how to do something to all elements of a list but the last.
The reasons I asked is because I had used ‘do’ loops in lieu of something better, and from what I can gather, you basically never write ‘do’ loops in Scheme (maybe once [...]
