Please refer to ChangeLog.html for the most recent changes

July 4, 2000

• An XML parser in a purely functional Scheme
• Scheme in Perl, or Perl as Scheme

June 4, 2000

• Secure Counting: counting members of a subset without revealing their identities
• Reading IEEE binary floats in R5RS Scheme

May 5, 2000

• Signals and threads in Scheme
• Self-referential values and invocations in a pure functional language
• Reference to Speaking HTTP: A File-Uploader Tool, USENIX ;login: -- vol. 25, No. 2 -- April 2000, pp. 6-14

April 7, 2000

• Concurrent and serializable computations, and the evaluation order for function's arguments and the body
• Unitary type as a self-referential set
• Added a reference to an online version of the article Speaking in Iostreams-ese, C/C++ Users Journal, v.15, No. 5, May 1997, pp. 47-55

March 5, 2000

• Purely-functional Object-Oriented System in Scheme
• Another example is added to Monads, Scheme, and IO: monadic string concatenation (with list as a monad constructor)
• Updated: Patch-free User-level Link-time intercepting of system calls and interposing on library functions, added a recipe for FreeBSD 3.2, and a few other changes per version 2.5 of the Advanced i/o, Networking, and Arithmetic Compression classlib

January - February, 2000

• Version 2.5 of the Advanced i/o, Networking, and Arithmetic Compression classlibh
• get-url and web agents in Scheme
• A functional-style framework to parse XML documents
• Knight's tours and matrices in Prolog
• Many faces of the fixed-point combinator

December 3, 1999

• Can computers do infinity?
• An ultimate static type system: division by zero as a type error
• Acyclic lists, innumerable trees, and surreal numbers

November 5, 1999

• C++ compiler as an expressive type inference engine
  which implements an ultimately static type system, to detect division by zero at compile time.
• Why C++ is not very fit for GUI programming, an old MacHack'95 paper and the presentation, converted into HTML.

October 1, 1999

• New input parsing functions: next-token-of, read-line, read-string. All the input parsing functions take an optional PORT argument. Functions next-token and next-token-of extend the token buffer in a Fibonacci-like fashion.
• New string manipulation functions: string-split (modeled after split of Python and Perl), string->integer and string-rindex.
• Added thorough validation code for all the new procedures.

August - September, 1999

• A read-time application: a value/code constructor
• Four evaluators of CL/Scheme and their bottom terms
• The read-time application proposal has been submitted as a SRFI-10 "#, external form: applying a value/code constructor at read time".
• IF as a pure function (in Scheme and Python)

August 1998 through July 1999
