Internet is not a safe place anymore...

I am not a regular poster. But I will nonetheless follow Robert Scoble's advice and take a break from blogging in support to Kathy Sierra. (Read the whole story here.)

lalr-scm as Snow package

lalr-scm v2.3.0, the latest version, has recently been released as a Snow package. lalr-scm is an efficient and portable LALR(1) parser generator Scheme.

This new release features an experimental GLR driver for ambiguous grammars. The LALR tables are built as usual, but instead of retaining a single action when conflicts are found, all possibilities are kept in the table for the GLR driver.

This release has only been tested on Gambit-C 4.0b20, Bigloo 3.0, and Chicken 2.6.

A few snowballs

We had a few centimeters of snow last weekend... I like winter a lot, but as soon as mid-March is passed, I prefer snow in its liquid form ;-).

Fortunately, this was the time for a few snowballs. I had time to package a number of the Scheme libraries I developed over the past few months. There are more to come, and documentation is still missing in many important places, but that's a start. The Snow packages that I have uploaded are:

• JSON - a JSON reader and writer
• Asterman - an interface to the Asterisk manager API
• FastAGI - a server for Asterisk FastAGI applications

New Erlang book

Joe Armstrong, the father of Erlang, has published a new book on Erlang: Programming Erlang: Software for a concurrent world. It's published by the Pragmatic Programmers.

Scheme Now! has been officially launched

Scheme Now! (Snow for short) is a repository of Scheme packages that are portable to several popular implementations of Scheme.

I really think this is a great achievement for the Scheme community and I hope we'll see lots of new packages ported to Snow in the near future. I will contribute some of them myself.

(The timing is excellent, my kids are at home today due to a snow storm! 25cm are expected.)
