AJAX Version of Mathematica Coming

Mathematica
has been long recognized as the world's best computer algebra system.
Stephen Wolfram originally conceived it of more than two decades ago
and since then the program has grown to become an unparalleled platform
for all forms of computing.

Now the O'Reilly School of Technology (OST) is poised to offer
Mathematica in its newest form: called "Hilbert" for the influential
mathematician, the newly licensed software will be browser accessible
and, utilizing AJAX technologies, will emulate the desktop version of
the software with remarkable fidelity.

Octave Home Page GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.
Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C , C, Fortran, or other languages.
