1. New Daylight Saving Time Rules: How They Affect Allegro CL

Countries around the world use different rules for Daylight Saving
Time. What's more, the rules in the United States are changing in 2007
so that its Daylight Saving Time is scheduled to start earlier and
last longer than it has in previous years.

This article describes how Allegro CL uses Daylight Saving Time and
how Allegro CL determines that a time is in Daylight Saving Time. The
article also describes how you can check that an Allegro CL running in
the United States is on a host updated to the new United States rules,
and how you can use the new United States rules in Allegro CL even if
the host has not been updated to the new rules.

2. Simulating Symmetric Multi-Processing with fork()

This article discusses example code that uses excl.osi:fork on
non-Windows platforms to utilize all available processors for Lisp
computations. It assumes that your application has compute bound parts
which can be run in parallel. Complete source code provided.

3. Free Web Seminar: Understanding Web 3.0 Database Technology

April 11 10:00 Pacific Time, 10:00 - 11:30 am Pacific.

The Web is entering a new phase of technological evolution. Attend our
free seminar to learn more about the database technologies underlying
the future of the Internet. Not everyone that wanted to last month
could attend so we're doing this one again, though there will be some
updated material based on the initial feedback.

Space is limited, so please R.S.V.P. to as soon as
possible. For more details:

4. Installing Allegro CL patches on Windows Vista

Windows Vista has a security model that disallows installation of
files into c:\Program Files\ for the non-Administrator. To install
patches for Allegro CL on Windows Vista, you should right click on the
Allegro CL icon and select Run as administrator. This will enable you
to install the patch files into c:\Program Files\. Note that you will
also need to use this method for running update.bat.

When you select Run as administrator you will need to answer in the
affirmative to the User Account Control dialog boxes Vista pops up.
