In this post I continue with the review of one of the classical references about this topic, the book “RESTful Web Services” by L. Richardson & S. Ruby (O’Reilly 2007). Even though it could be considered an old reference and even the authors recognize that the ROA term could be controversial, for lots developers this books is the first step in the path of web programming. Additional post will follow this one.

In term of ROA concepts, design web services means turning requirements into resources specifications. From those specifications, a "real" web services can be implemented in whatever programming language and deployed in a web server.

The "Restful web service" reference proposes the following methodology:

• Figure out the web service data set.
• Split the data set into resources, defining:
• the name of the resources with URI.
• the subset of method of the uniform interface for those resources.
• representations accepted from and server to the client.
• hypermedia links between resources.
• Interactions and error (dynamic) between client and server.

Después de haber oído hablar de él mucho tiempo, comienzo a leer Camino de Servidumbre, de Friedrich A. Hayek, destacado economista de la denominada Escuela Austriaca.

Apenas llevo un par de capítulos y ya tengo la sensación que mucho de lo que se dice del texto y del autor parece venir de personas que no han lo han leído. Sin ir mas lejos, el autor insiste en la introducción que liberalismo no es laissez-faire, llegando incluso a afirmar que "nada ha hecho tanto daño a la causa liberal como la rígida insistencia de algunos liberales en ciertas toscas reglas rutinarias, sobre todo en el principio del laissez-faire".

Eric Arthur Blair
a.k.a
George Orwell

Durante mi último viaje a Madrid, compré la nueva edición de Homenaje a Cataluña[1], de George Orwell[2]. Las principales diferencias respecto a las ediciones disponibles en castellano hasta este momento eran significativas, fruto de la censura a la que fue sometida la edición inicial, origen deforme de todas las siguientes.

El texto, que aún no he concluido, resulta a todas luces recomendable. De hecho, la reflexión suscitada a raíz de la lectura de un párrafo del actual capítulo 7, está en el origen de la presente diatriba intelectual.

Dice el autor en la página109, correspondiente al capítulo 7:

"[...] por fortuna, también existe una visión muy diferente del socialismo. Lo que atrae a la gente normal hacia el socialismo y la empuja a jugarse el pellejo por él, la mística del socialismo, es la idea de igualdad; para la mayoría de la gente, el socialismo significa una sociedad sin clases o no significa nada."

Emperors became silhouettes, didn't they?

.... ha vuelto a pasar... la tipica broma estoica a expensas de la filosofia especulativa epicurea...

Early in the morning, I finished "I, Claudius" by R. Graves (1934) and I have not been be able to wait to write the post about the book.

Even although it is a very personal view of the first steps of the Roman Emperors dynasty, the novel shows interesting aspect, not just about political power but business power, sociological power and even home power as well. Obviously, Livia was not my grandmother and Tiberius is not my boss, but now everything makes a little bit more sense.

After 20 centuries, we still remain governed by instictics, fears and spirit's ghost. Then a young "little soldier's boot" was able to hide madness behind excentricity, feeding to the excesses. Only a broken german barrier, allowed the Praetorian Guards to free the roman people. But again, like a joke, the deafness became emperor. After a whole life dying, Claudius was born.

ROA for newbies

Web APIs are becoming in a “de facto” operating system. By using these abstractions developers populate Internet with m2m services i.e. with new APIs. The main criteria of this process are mainly usability, fostering the service integration or creation mash-ups. However there exists some theoretical framework backing this phenomenon: Resource Oriented Architecture (ROA).

In this post I review one of the classical references about this topic, the book “RESTful Web Services” by L. Richardson & S. Ruby (O’Reilly 2007). Even though it could be considered an old reference and even the authors recognize that the ROA term could be controversial, for lots developers this books is the first step in the path of web programming. In this post, some basic concepts and principles will be presented, letting some design clues for the followings.

Empathic review of thoughts in crisis

My personal review about "The Empathic Civilization: The Race to Global Consciousness in a World in Crisis" of J. Rifkin.

This kind of books shows an ideal future built on top of personal best wishes and at the same time many of the risks that will make imposible to reach that future. Unfortunatelly the book doesn't contain any tactics to reach the described future. The book seems to feed the readers' fear to drive them to certain opinions.

Mr Rifkin merges together data coming from different sources but he is unable to create a logical narration supporting the tittle of the book. Nonetheless, the bibliography included seems to be more solid.

All the long Mr. Rifkin affirms one thing and its contrary, seemingly trying to make feel everyone happy. To make everything worse, he follows approaches of postmodernism and deconstructivism, which have showed so interesting in many areas but not in the social and political sciences.

La Civilización Empática y el (no) Modus Ponens

Hasta ahora mismo he venido haciendo algunas reflexiones sobre mi lectura de "La Civilización Empática" de Jeremy Rifkin en mi cuenta de failboot. Pero debido a la extensión que empieza a tomar, he decidido llevar dichas reflexiones a mi blog, así darle algo de vida. Así que allí vamos.

Durante esto días de lectura, el autor menciona de "deconstrucción" y "generación postmaterial", llevando el asunto del mundo de la filosofía al de la sociología y esto, evidentemente no iba a traer nada bueno. La verdad es que desde el principio tuve la sensación de que se trataba de un libro apto para aquellos que no conocen o les trae sin cuidado el Modus Ponens y otras reglas de inferencia. Después de algunas páginas más, la confusión me aconseja compartir los motivos del desconcierto, en la búsqueda de cierta luz.
