Finally CDF is with us. Chrome has plugins to run this kind of format. I run one of their examples, Dopamine, and followed the instructions to put it in this blogger page. It is on the side column.

Wolfram|Alpha Widgets

One can write widgets with Mathematica. Many years ago my son made a widget for digg.com. When he posted it, he came home excited from highschool to see how many diggs it had, in one day there were hundreds. Then an Apple magazine published it in England. I joined digg, and now I embed a Mathematica Widget posted today by prezjordan in the Wolfram portal. You can see it on the side bar.

10 Reasons to use Mathematica

Here are  10 good reasons to use Mathematica:

1. Multiparadigm language:   the richness of the language allows to pick for any problem a programming paradigm or style which corresponds to it most directly. You spend most of the time thinking about the problem rather than implementation. The very high level of the language means that a lot of work is done for you by the system.

2. Interactivity. Mathematica  is an interpreted language, which allows interactive and incremental program development. The Mathematica  front - end adds another layer of interactivity, being able to display various forms of input and output (and this can be controlled programmatically). Yet another layer of interactivity is added by many new features of version 6.

3. Programming in the large. The typically small size and high level of abstraction of the code allows a single person to manage substantial projects. There is also a built-in support for large projects through the system of packages.

3. Built-ins. Availability of thousands of built-in functions makes it possible to do sophisticated analysis very quickly. Extended error message system (each built-in function can issue a lot of error messages on improper inputs) greatly simplifies debugging.

4. Genericity, higher-order functions and tight system integration. The very general principles of Mathematica, its uniform expression structure, generic nature of many built-in functions, and tight integration of all components  allows to use all other built-in functions much easier than one would use libraries in other languages. The Help system is also uniform and it is immediate  to learn the functionality of any built-in function that you have never used before.

6. Visualizations. Great dynamic and visualization capabilities (especially in version 6).

7. Cross-platform.   The Mathematica  code developed in one environment or OS will work in exactly the same way in all others where Mathematica  is available.

8. Connectivity: the developers keep increasing the number of file formats which Mathematica  can understand and process. Also, tools like MathLink , J/Link , database connectivity etc. allow one to connect Mathematica  to external programs

9. Backward compatibility: since the version 1 and up to these days developers are careful to maintain very high level of backwards compatibility. This means that one should not worry too much that solutions developed in the current version will need a rewrite to work on the future versions (apart from possible improvements related to availability of new built - in functions, if one is so inclined).

10. Support for parallel and distributed computing.

Writing Code

A complete Mathematica installation, has c, and some others, code accessible by users. It is found, among other places, in

/usr/local/Wolfram/Mathematica/8.0/SystemFiles/Links/Python

Therefore, one can interact with Mathematica at the code level. Obviously one has to know those languages.

This screenshot is from the c code mathlink.c, in the Python directory. Also there are a few more .py programs there.

Widgets

I joined digg.com, because my son posted a widget to have digg on your PC desktop all the time. Very fast he got hundreds of downloads. His widget even appeared in a MacIntosh magazine.  I now have two Mathematica widgets in Relevant Science.

You can read about them in Wolfram|Alpha Widgets.

Can one Make a Living Writing Mathematica Notebooks?

I see a parallel between iTunes and Mathematica. Given the success of the parent companies in establishing a working business model, it is possible to write software products that will actually sell, thus leveraging the programming abilities of free agents all over the world.

Mathematica v.s. Open Source

El Dr. Dante Covarrubias Melgar, quedó satisfecho con el evento de software libre organizado por la UAM-UAGro: FLISoL Chilpancingo.  Obviamente hay ventajas, como pueden leer aquí.  Aquí escribo mis ideas sobre el software privativo al cual está dedicado este blog.

Antes de presentar mis ideas, tengo dos disculpas: Primero, el idioma de este blog es el SpanGlish. Realmente no domino fluidamente este idioma, que hablan nuestros paisanos, los Chicanos; por lo cuál prefiero escribir cada nota sólo en un idioma.  Segundo, el énfasis es software privativo.  Casi todo lo que escribo es a favor de software libre. Tengo al menos un lector, Luis Montgomery Antelo, que principalmente usa software libre. En esta nota escribo mis razones para esta actitud esquizofrénica, en los dos aspectos. Pueden ver mi profile,   aquí. Soy responsable de 28 blogs, este blog es el único en que me pongo de lado de, y sólo escribo sobre, una empresa privada. Siguen mis justificaciones.

Idioma


Aunque ya impartí un curso de inglés en el nodo de Iguala, realmente no veo la necesidad de escribir todo en inglés aquí.  Mi público para este blog es principalmente de habla hispana. Uso el inglés porque, por ser privada, Wolfram Research no tiene los recursos para ofrecer Mathematica en Español todavía. Además si quieren trabajar para Mathematica, tendrán que aprender inglés. Es posible trabajar en línea con esta empresa.

Mathematica v.s. Open Source


Mi razón para solicitarle al Dr. Covarrubias la compra de una licencia de Mathematica, es que no existe ningún producto de software libre liderado por un científico del calibre de Stephen Wolfram, desde mi humilde punto de vista, la UAGro ganará, más de lo que perderá, por pagar esta cuota. Quiero establecer una relación de cooperación con esta empresa, y creo que no se vería bien que empezáramos robándales   su producto.

Ahora que vaya a mi casa en Illinois en estas vacaciones, espero comprar una licencia de estudiante a nombre de mi esposa, pues está haciendo su doctorado en Historia, y es estudiante registrada. Los mantendré informados por este blog del desarrollo de este propósito.

Hello World from Chilpancingo!

Last week we had a successful Mathematica 8 Workshop. Enrique Zeleny visited us here in Chilpancingo, locally known as Chilpo.

This blog address is:

http://mathematicachilpo.blogspot.com/

Here I write about this fundamental software instrument, which I believe will lead the way to the XXI^st century for Science.

Not since Zeno of Elea asked his peers to think about an arrow's motion, has there it been a call to action more fundamental than this: Stephen Wolfram is asking us to look at the structure of computer programs as a new language to describe Nature.
