Arboretuum Forest-Rewriting Language Released
March 4, 2008: The Arboretuum programming language has been released. It is based on forest-rewriting, which, as the name suggests, is an extension of tree-rewriting in which multiple trees are rewritten simultaneously.

Website Updated to Use XHTML 1.0
Jan 31, 2008: We have updated our webpages to conform to the W3C Recommendation XHTML 1.0. (This does not, however, apply to HTML documentation in projects.) The CSS has also been cleaned up significantly, and the site generally looks better in Internet Explorer.

Release of the Larabee Programming Language
Jan 10, 2008: The Larabee programming language has been released. Larabee borrows the notion of branch prediction from computer architecture, and abuses it to create a state of total despair. Also great fun at parties.

Release of the Mascarpone Programming Language
December 8, 2007: The Mascarpone programming language has been released. Mascarpone is a rationalization and further exploration of some of the ideas behind Emmental. Mascarpone is a self-modifying language, defined by a meta-circular interpreter, in which interpreters are also first-class values.

Ypsilax Updated to Use Console::Virtual
December 2, 2007: Following the improvements made to the implementation of noit o' mnain worb, our Ypsilax implementation also uses Console::Virtual and optional sub-second delays to provide a nice screen-oriented animation of Ypsilax' two-dimensional, non-deterministic, reflective grid rewriting, taking the burden of visualization off the user.

RSS Feed Now Available for Cat's Eye Technologies
December 1, 2007: News on the latest developments at Cat's Eye Technologies is now available as an RSS feed. The news page is still available, but it is now automatically generated from the RSS feed by an XSLT stylesheet.
This may seem like a bit of a dodgy move, for a company with as staunch an attitude of post-modernist rectitude as Cat's Eye Technologies to go adopting technologies that are clearly of Pakled origin.
However, there are several good reasons. Firstly, XSLT, being a Turing-complete macro-expansion language with all the readability of Scheme, is practically an honourary esolang. Secondly, RSS is specified about as rigorously and consistently as most esolangs as well. And thirdly -- although I dispute that this is a particularly important reason -- somebody might actually find it useful.

Release of the Iphigeneia Programming Language
November 25, 2007: The Iphigeneia programming language is released. Iphigeneia is a toy programming language which contains features from both imperative programming and functional programming. It was originally intended as a testbed for algorithms that convert programs between the two forms, but it has strayed slightly from that goal.

Console::Virtual Revived, HUNTER and worb Benefit
November 23, 2007: Noticing that the Perl 5 implementation of HUNTER required a module that was never restored to the website after the last crash, I dug it out of cold storage and refurbished it a bit, resulting in Console::Virtual.
In the process I tidied up the HUNTER project quite a bit, including supporting a real delay, measured in milliseconds, between animation frames. (This requires the Time::HiRes module, but it still works without it; you just can't get sub-second resolution in that case.)
And, in the process of doing that, I noticed the implementation of noit o' mnain worb could use many of the same improvements. So now it, too, uses Console::Virtual instead of requiring an ANSI-compatible terminal, and supports an adjustable delay between frames.
Concurrent with this project interdependency, I've made a quick stab at listing the requirements for each project in the little "info box" on its project page. This is pretty crude right now, but it's hopefully a step in the right direction.

Release of the Didigm Reflective Cellular Automaton
November 17, 2007: Release of initial specification of the Didigm reflective ceullar automaton.
Also some random hacking on libvesa.

Release of the Emmental Programing Language
November 11, 2007: The Emmental programming language has been released. Emmental is a self-modifying programming language; it is defined in terms of a meta-circular interpreter, and this meta-circular interpreter provides operations that modify its behaviour. In fact, Emmental requires that this mechanism of meta-circular self-modification in order for it to achieve Turing-completeness.

Release of You are Reading the Name of this Esolang
November 5, 2007: The programming language You are Reading the Name of this Esolang was released. It's an exploration in the design space of programming languages with undecidable elements. Specifically, the problem of whether or not a given string of symbols is a well-formed You are Reading the Name of this Esolang program is undecidable.

Release of the Cabra Programming Language
November 1, 2007: The Cabra programming language, successor of sorts to Burro, has been released. Cabra programs form, not a group, but a dioid -- an idempotent semiring -- under the operations of sequential and parallel composition.
Check it out at http://catseye.tc/projects/cabra/
Release of the Burro Programming Language
October 26, 2007: The Burro programming language, after two years (on and off) of design work, has finally been released. Burro is a Brainfuck-like language whose programs form an algebraical group under the operation of concatenation (roughly speaking -- see the docs for the complete picture.)

(Re-)Unearthing of the Maentwrog Programming Language
September 30, 2007: The Maentwrong language, predecessor of Befunge-93, and thought by me to be lost forever (again), was found (again) on a long-forgotten backup disc. It has been brought forth into the light of the projects directory (again) for whatever it's worth.

catseye.mine.nu No Longer in Service
August 28, 2007: The catseye.mine.nu server is no longer in service This has two consequences: The old http://catseye.mine.nu:8080/ URL prefix for this site will no longer redirect here to catseye.tc, and the Subversion repositories served by catseye.mine.nu will no longer be publicly available.
The catseye.webhop.net redirect will continue to work, and the tarball releases of projects will still be available from catseye.tc.
Whether the catseye.mine.nu server will ever go up again or not depends on too many factors for me to be able to say at this time. I definately want to keep providing publicly available source code repositories of the projects, but due to circumstances it will have to be a low priority goal over the next few months.

Updates to SMITH and REDGREEN
July 22, 2007: The SMITH language has been updated in a tiny but significant way: overwriting instructions with other instructions is now defined. The reference implementation now implements this sanely as well. Thanks to Nathan Thern for pointing this out (and for submitting a SMITH version of "99 Bottles of Beer"!)
Some bugs in REDGREEN have been fixed as well: the documentation claims that Wires and Sparks behave per the WireWorld automaton, and that Zappy and BigZappy set things on fire. The ALPACA implementation of REDGREEN now properly implements these rules. Thanks to Stewart Gordon for pointing these bugs out.
Also, I dug up noise and put it in the projects. I swear there was a manual page for it too, but I can't find it.

Release of the Hev Programming Language
June 17, 2007: The Hev programming language has been released. Hev allows programming in infix notation, but at the same time, never needs parentheses and never forces you to memorize precedence tables! Truly, a major breakthrough.

Release of the Xigxag automaton
June 2, 2007: Xigxag, a simple automaton with exponential growth almost everywhere, has been released.

Zzrk Released, and More
May 15, 2007: Most significantly, a project has been added for Zzrk, a text adventure game written in a meta-language intended for building compilers (Zz).
I also brought GraNoLa/M and SP\ASM out of those dusty ol' boxes in the attic and added them to the line-up.
REDGREEN, Braktif, and Circute have also been split off from the main ALPACA distribution, and live in projects of their own.
I also polished the site design a wee bit.

Launch of catseye.tc!
April 28, 2007: We've moved from catseye.mine.nu:8080 to our new domain, catseye.tc!
While it was fun serving my website with my own webserver software off of my own computer, it was a headache too -- both for me and, I'm sure, everyone out there in user-agent land as well. But now we're hosted on a commercial server which will, with any luck, provide much better bandwidth and reliability.
A few other minor things about the site have changed. For more details, see About this Website.
A few projects were also dug up and added to our line-up: Kangaroo Iceberg, libvesa, LuaKLD, 'N-DCNC, Opus-2, and Ribos. Also, each of the various incarnations of ILLGOL (ILLGOL, Illgola-2, Illberon, and Open Sores Illgol##) was given its own project, and historical source code has been found and added to ILLGOL and Illgola-2.
