Source Code for Various Old Scheme Implementations
Friday, November 14, 2008
The source code for various, older, Scheme implementations can be found here. It is pretty interesting to read about the differing interests of the implementers.

Beating the Odds: 3 Tenets of Good Software
Thursday, November 13, 2008
Lately I’ve noticed three key traits about software that is generally recognized as “excellent” by technical folks. At its core, said software is simple (it does a few things, very, very well), it its highly reliable (correct, predictable, stable), and it is extensible (by the user).
Bazaar Marketing Practice
Monday, November 10, 2008
I recently cut over from Subversion to Bazaar. Happy to see that a new, improved version, 1.9, was released; I headed over to the download area only to find a RC1 version available. There were only two 1.9 releases available: source code or a Mac installer. Apparently the Windows installer will be available in a [...]
A Theory for Language Design
Thursday, November 6, 2008
No amount of language design can force a programmer to write clear programs. If the programmer’s conception of the problem is badly organized, then his programs will also be badly organized. The extent to which a programming language can help a programmer to organize his problem is precisely the extent to which it provides features [...]
Helium for learning Haskell
Monday, November 3, 2008
Helium is a user-friendly compiler designed especially for learning the functional programming language Haskell. The quality of the error messages has been the main concern both in the choice of the language features and in the implementation of the compiler. Helium implements almost full Haskell, where the most notable difference is the absence of type [...]
A peasant revolt against DrScheme!
Sunday, November 2, 2008
Here is an interesting thread in the PLT discussion archive discussing the want of beginning programmers only to learn things that are clearly useful!
(surely via the PLT Discussion list, but I can’t recall or find it…)
An Improved Approach to the Sieve of Eratosthenes

For an explanation and easy improvemnts see Colin Runciman’s functional pearl “The primes using The Sieve of Eratosthenes”.

Finding the real problem
Wednesday, October 29, 2008
The poster of this thread on the PLT discussion list wondered why Scheme code is so much slower than Python. It was interesting to see how the question was answered because there were at least 3 levels to the problem:
The source code to the solution itself
How the source code worked “under the covers” (it called [...]
