Sharismo: la esencia de la web 2.0 [Post al Blog El Caparazon]
Gràcies al Jose A Salazo he descobert aquest interessant post al blog de El Caparazon, d’una dissenyadora-web, i que en breu comentaré. Però no puc esperar a tenir temps per a fer-ho per a comentar-ho. Aquí les primeres línies del post:
Es una de las preguntas que acecha a muchos desde el éxito rotundo, primero del P2P, después de la web 2.0…. ¿Porqué compartimos? ¿Hemos querido hacerlo siempre? ¿Porqué lo hacemos ahora? ¿Qué ganamos con ello? Y relacionado con todo ello ¿Cómo fomentar la interiorización de esta actitud, imprescindible para la participación en cualquier comunidad? En cuanto a los bloggers, a pesar de haber recibido críticas ilustradas o comentarios de trolls ocasionales, muchos seguimos pasando nuestras horas escribiendo materiales, motivándonos en mayor medida cuanto más nos acercamos a las necesidades de quienes nos leen, cuanto más….Compartimos. Responde a estas preguntas el reciente texto de Isaac Mao, traducido por Emilio Quintana. Y no es que sea una idea nueva. Hereda ideas del Conectivismo en aprendizaje, de la Intercreatividad (Berners-Lee), la Inteligencia colectiva (Lévy), las Multitudes Inteligentes (Rheingold), la Sabiduría de las Multitudes (Surowiecki) o la Arquitectura de la Participación (O’Reilly).
Per a llegir el post sencer: aquí.

Les vaques porten esquella i la merda fa pudor!
Passo-reenvio aquesta denúncia en contribució al meu origen rural, a la meva família i amics pagesos i per donar un clatellot als urbanites i kamakus!!.
Visca els pobles, visca el món rural… tal com és!!
Ja n’hi ha prou! La població rural de Catalunya està patint una amenaça! Des de fa segles les campanes dels pobles toquen cada hora, les vaques, les ovelles i els cavalls porten esquelles al coll, els galls canten a la matinada i la merda fa pudor (com no pot ser d’altra manera). Darrerament hi ha hagut un gran augment de població urbanita “post moderna” que fa turisme rural per “respirar aire fresc” i “viure la natura”. Això no hauria de ser un problema si no fos perquè alguns d’ells, Ajuntaments i constructores estan posant en perill la tasca dels pagesos i ramaders. Es veu que les esquelles i les campanes “molesten”, els galls “criden” massa i els tractors “destorben” a la carretera, i segons algun Ajuntament no es cumpleixen alguna norma que s’han tret de la màniga. Serà certa la dita tan nostrada “de fora vingueren que de casa ens tregueren”? No hi ha cap problema en compartir el món rural, el que cal és respectar-lo com es mereix. A Catalunya tenim la sort que hi ha gent que pot viure encara de l’agricultura i ramaderia, una tasca que, de moment, no fa fums ni cal posar límits de velocitat a les vaques perquè pasturin. La muntanya no és Port Aventura! És real i és de veritat! Ajudem tots plegats perquè segueixi sent així. Passa-ho.

Campanya de la FSF: Escriu un e-mail a la IEFT per evitar un protocol amb patent
From: http://www.fsf.org/news/reoppose-tls-authz-standard
Last January, the Free Software Foundation issued an alert to efforts at the Internet Engineering Task Force (IETF) to sneak a patent-encumbered standard for “TLS authorization” through a back-door approval process that was referenced as “experimental” or “informational”. The many comments sent to IETF at that time alerted committee members to this attempt and successfully prevented the standard gaining approval. Unfortunately, attempts to push through this standard have been renewed and become more of a threat. The proposal now at the IETF has a changed status from “experimental” to “proposed standard”.
The FSF is again issuing an alert and request for comments to be sent urgently and prior to the February 11 deadline to: ietf@ietf.org Please include us in your message by a CC to campaigns@fsf.org
That patent in question is claimed by RedPhone Security. RedPhone has given a license to anyone who implements the protocol, but they still threaten to sue anyone that uses it. If our voice is strong enough, the IETF will not approve this standard on any level unless the patent threat is removed entirely with a royalty-free license for all users. Further background for your comment: Much of the communication on the Internet happens between computers according to standards that define common languages. If we are going to live in a free world using free software, our software must be allowed to speak these languages. Unfortunately, discussions about possible new standards are tempting opportunities for people who would prefer to profit by extending proprietary control over our communities. If someone holds a software patent on a technique that a programmer or user has to use in order to make use of a standard, then no one is free without getting permission from and paying the patent holder. If we are not careful, standards can become major barriers to computer users having and exercising their freedom. We depend on organizations like the Internet Engineering Task Force (IETF) and the Internet Engineering Steering Group (IESG) to evaluate new proposals for standards and make sure that they are not encumbered by patents or any other sort of restriction that would prevent free software users and programmers from participating in the world they define. In February 2006, a standard for “TLS authorization” was introduced in the IETF for consideration. Very late in the discussion, a company called RedPhone Security disclosed (this disclosure has subsequently been unpublished from the IETF website) that they applied for a patent which would need to be licensed to anyone wanting to practice the standard. After this disclosure, the proposal was rejected. Despite claims that RedPhone have offered a license for implementation of this protocol, users of this protocol would still be threatened by the patent. The IETF should continue to oppose this standard until RedPhone provide a royalty-free license for all users.

Desmitificant les xarxes socials online: contactes no son interaccions, obviously
Esteban Moro Egido, a un pots a una llista dona compte d’un estudi sobre les xarxes socials online i la seva dinàmica, molt menor que del que la seva “estàtica” (les “fotos” i representacions de les xarxes personals, sempre molt presents en aquests aplicatius online) ens sembla indicar. Diu:
Social Networks that matter: twitter under the microscope. B. A. Huberman, D. M. Romero y F. Wu http://firstmonday.org/htbin/cgiwrap/bin/ojs/index.php/fm/article/view/2317/2063
El artículo incide en un aspecto que me parece muy importante: en cómo se descubren/analizan actualmente las redes sociales. Aunque el estudio se realiza sobre la red de seguidores y seguidos en el twitter, tiene aplicación a otras redes sociales. La conclusión del estudio es que aunque la red de contactos sociales en redes como Twitter, Facebook, etc puede ser muy densa, la red real de interacciones entre actores es muy “hueca” o sparse.
Como dice Huberman, la red social que de verdad interesa es la de interacción, no la de contactos.
Algo parecido estamos haciendo nosotros con las redes sociales a partir de comunicación por internet.
