This is the first production release of Lafcadio, which is an
object-relational mapping layer for use with Ruby and MySQL. It lets
you treat database rows like first-class Ruby objects, minimizing the
amount of time you have to spend thinking about MySQL vagaries so you
can spend more time thinking about your program's logic.

While some of the features are a little rough, Lafcadio is solid enough
for me to have used in on three professional projects (all of them
database-driven web sites).

Lightweight Languages Workshop 2003 (LL3)

Saturday, November 8, 2003, MIT, Cambridge, MA


LL3 will be an intense, exciting, one-day forum bringing together the
best programming language implementors and researchers, from both
academia and industry, to exchange ideas and information, to challenge
one another, and to learn from one another.

The workshop series focuses on programming languages, tools, and
processes that are usable and useful. Lightweight languages have been
an effective vehicle for introducing new features to mainstream

We encourage presentations on topics of interest to the community of
lightweight language users and designers. We prefer topics that will
interest a broad audience. We do not require the presentation of
novel research ideas.

Proposal Abstracts
Due Friday Oct. 17

We seek two to five page abstracts of talks to be given at the
workshop. Talks will be 30 minutes long, including time for
questions and answers. Presenters are not expected to submit
papers, but slides will be published on the workshop web site.
We will also consider proposals for talks of different lengths.

Some suggested topics are:

* Language design: New language features, type systems and other
reasoning tools, critiques of existing languages.

* Implementation techniques: Interpreters and virtual machines,
optimizations, cross-language interactions.

* From scripts to programs: Software engineering with
lightweight and/or a mix of languages. How to (or not to!)
scale from little scripts to large, complex applications.
Application war stories.

* From ivory tower to cubicle -- what language implementors need
to know from academic programming languages research -- and

* Lightweight pearls: Elegant and instructive examples of
programs in lightweight languages.

* Programming tools and development processes.

Send submissions to: [email][/email]

We want presentations that will inspire, motivate, and educate. We
want language implementors and researchers to leave the workshop fired
up with ideas for future languages, features, and implementation
tricks. We want language users to leave the workshop fired up with
new ideas and new tools.

In addition to submitted presentations, there will be two invited
talks. After the workshop, there will be an evening social event and

Dates: Tuesday, Oct. 17 -- submissions due by end of day.
Tuesday, Oct. 24 -- notification of acceptance or rejection
Saturday, Nov. 8 -- 9am-7pm, LL3!
