Yeah, its too bad. I really thought I could make it. Well maybe next
year...

I haven't been working on them since this summer. I'm ashamed of this,
especially for RubyVM since a number of people volonteered and even
started writing code. I've been a bad project coordinator.
Reasons are I've been getting married, writing a few chapters for an
upcoming Ruby book and been sick. Its been interesting months... ;-)

Rockit will see some updates pretty soon. When it was released I got some
bug reports but haven't heard much since then; I guess I thought no one
was really interested. If you are then please mail bug reports, ideas for
future development or some encouragement...

RubyVM got stuck on the RubyInRuby parser stuff; it turns out I didn't
really understand the quirks of the Ruby grammar well enough to replicate
its behavior. As an intermediate step we may use Ruth
(http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/rubyvm/src/other/ruth/) which
(stop reading now Matz! ;-)) uses Matz parser, converts the internal trees
to Ruby objects, which can then be translated to RubyAST or
RubySchema. From the outside it should look like a RubyInRuby parser and
parse the same stuff as Matz interpreter.

While we're at it I might mention some other Ruby stuff I've been playing
with:

* RbProf - Ruby profiler as an aspect in AspectR (faster and more flexible
than profile.rb, can even be forced to output call graphs (to
graphviz/dot) that will show the critical path (some day!))
* PerfCtr - wrapper of PAPI for high-resolution timers (right now it does
not use PAPI but simply gives a high-resolution timer on Windows
platforms since PAPI not available for windows (but it will soon be))
* JxtaRuby - Ruby implementation of protocols for Jxta p2p framework (very
alpha...)
* Yoda - Yet anOther Distributed execution frAmework. X@home � la
Seti@home. (also very alpha should be converted to use Jxta!)

If anything sounds interesting drop me a note and I'll try to change the
release plans... ;-)

Sorry for wasting bandwidth.

Have a great conference!
