Maxima released!

From the mailing list of Maxima software:

Announcing Maxima 5.24

Maxima is a GPL'd branch of Macsyma, the venerable symbolic
computation system. Maxima 5.24 is a bug fix and feature
enhancement release. The current version is 5.24.0.

Maxima has functions to work with polynomials, matrices, finite sets,
integrals, derivatives and differential equations, linear algebra,
plotting, floating point and arbitrary-precision arithmetic, etc.

Maxima can run on MS Windows and various flavors of Unix,
including MacOS X.
There is a precompiled executable installer for Windows,
RPM's for Linux, and source code tar.gz.

Maxima is implemented in Common Lisp; several Lisps can compile
and run Maxima, including CMUCL, SBCL, Clisp, GCL, and ECL.
The default Windows installer (maxima-5.24.0.exe) was compiled
with GCL, while maxima-5.24.0-ccl.exe was compiled with Clozure CL.

The Maxima project welcomes new participants. You can contribute
in several ways: reporting bugs, fixing bugs, writing new add-on
packages, revising core functions, user interfaces, documentation, ....
Why not see what's happening on the mailing list and consider how
you might contribute to the project.

Thanks to everyone who contributed to the 5.24 release.

Regards,
Robert Dodier
Maxima developer and 5.24 release manager

The current stable version at maxima.sourceforge is 5.18.1, which is older than my Ubuntu 10.04 package version Maxima 5.21.1!

Installing the latest version over the Ubuntu version may result in aggravations. You are on your own.

Our main blog is suffering from WP supercache bug.

When I put the url http://adorio-research.org in the address bar of the browser, I only get a blank page! Here is the contents of the blank page with the comment delimeters removed:



Page not cached by WP Super Cache. Blank Page. Check output buffer usage by plugins.

Page not cached by WP Super Cache. No closing HTML tag. Check your theme.

Yet when I go to a specific post like http://adorio-research.org/?p=3470,that post jus shows up fine! Going to settings of the plugins, I get this one for WP Super Cache:

Permlink Structure Error

A custom url or permalink structure is required for this plugin to work correctly. Please go to the Permalinks Options Page to configure your permalinks.

I wanted to remove the WP Super Cache plugin but it does not appear in the list of installed plugins! We have an unhappy future days trying to fix this WP Super Cache problem.
