code year
by Angelo Raffaele Meo Jan. 16, 2012

Jan. 16, 2012

carissimi, a proposito di Bloomberg e del code year (http://codeyear.com) di cui abbiamo discusso qui (vedi anche l'interesse di Anna Masera e l'articolo di Bernardo Parrella su La Stampa), consentitemi un'operazione di marketing. All'indirizzo http://linuxdidattica.org/polito/manuale-python-V2.pdf trovate un manualino, assolutamente free, per imparare a programmare in python. E' stato sperimentato con i bimbi di alcune classi della scuola media "Amedeo Peyron" nel laboratorio di informatica. Alla fine del corso i bambini, che si sono divertiti molto, programmavano anche le animazioni, senza usare le librerie precotte di Pygame, ma disegnando l'immagine, programmando il tempo di attesa, e disegnando l'immagine successiva. Il corso è durato circa 30 ore, ma un adulto può imparare in una decina o poco più. Meo

Joi Ito: "Why we need to stop SOPA and PIPA"
by J.C. DE MARTIN Jan. 16, 2012

Jan. 16, 2012

Why we need to stop SOPA and PIPA /»/ <http://joi.ito.com/weblog/2012/01/15/why-we-need-to.html> Jan 15, 2012 - 07:29 UTC <http://joi.ito.com/weblog/2012/01/15/why-we-need-to.html> » I just posted a blog post on the MIT Media Lab blog officially taking a position against SOPA and PIPA. This is a longer blog post co-authored with Ethan Zuckerman <http://www.ethanzuckerman.com/blog/2012/01/15/mit-media-lab-opposes-sopa-pi…> describing the issue in more detail. SOPA - the Stop Online Piracy Act <http://thomas.loc.gov/cgi-bin/query/z?c112:H.R.3261:> - and a sister bill, PIPA - the Protect IP Act <http://thomas.loc.gov/cgi-bin/query/z?c112:S.968:> - seek to minimize the dissemination of copyrighted material online by targeting sites that promote and enable the sharing of copyright-protected material, like The Pirate Bay. While this goal may be laudable, entrepreneurs, legal scholars and free speech activists are worried about the consequences of these bills for the architecture of the Internet. At the MIT Media Lab, we share those concerns, and we oppose SOPA and PIPA as threats to innovation on the Internet. To limit access to rogue sites, SOPA and PIPA would: - supersede the "notice and takedown" method of policing for copyrighted material on Internet services and require service providers to police content uploaded by users or prevent users from uploading copyrighted content - require Internet Service Providers to change their DNS servers and block resolution of the domain names of websites in other countries that host illegal copies of content - require search engines to modify their search results to exclude foreign websites that illegally host copyrighted material - order payment processors like PayPal and ad services like Google AdSense to cease doing business with foreign websites that illegally host copyrighted content Major internet companies, including Google, Facebook, Twitter and others, oppose SOPA and PIPA because it changes the liability rules around copyright infringement. Under the Digital Millenium Copyright Act of 1998, companies are protected from charges of "contributory infringement" on content uploaded by users, so long as the company follows a procedure and remove infringing content when an alert process is followed. SOPA substantially alters this system, and internet companies worry that without protection from contributory infringement, user-generated content sites like YouTube and Twitter would not have come into existence. The burden of reviewing user-submitted content - every blog post, every video, every image - would be impossible for a company to manage, and companies would have likely stuck with the Web 1.0 model of publishing edited, vetted content instead of moving to a Web 2.0 model where users create the content. Several internet companies took out a full-page ad in the New York Times <http://boingboing.net/2011/11/16/internet-giants-place-full-pag.html> to express their concerns about SOPA and PIPA. Free speech advocates, like the Electronic Frontier Foundation <http://eff.org>, worry that SOPA may provide powerful new tools to silence online speech. Confronted with uncomfortable political speech, repressive governments often seek to silence dissent by reporting content as defamatory, slanderous or copyright infringing, hoping the companies hosting the speech will remove the content. SOPA accelerates the process of copyright removal, with a mechanism that permits copyright holders to obtain court orders against sites hosting copyrighted materials and have those sites rapidly blocked. Scholars of online censorship, likeRebecca MacKinnon at the New America Foundation, worry that SOPA may be popular with the Chinese government <http://edition.cnn.com/2011/12/14/opinion/sigal-mackinnon-copyright-interne…> as with the copyright holders who are lobbying for the bill. US law already permits the seizure of domestic domain names that are used for piracy, and the US seized 150 domains in November. SOPA is an attempt to enforce copyright provisions across international borders by prohibiting American internet users from accessing certain foreign websites, like The Pirate Bay. In effect, it would create a firewall to prevent users from accessing prohibited intellectual property, much as China's "great firewall" limits access to politically sensitive information. Harvard legal scholar Lawrence Tribe believes that SOPA is likely unconstitutional, as it can remove constitutionally protected speech without a hearing, a form of "prior restraint". In a memo sent to members of Congress <http://www.net-coalition.com/wp-content/uploads/2011/08/tribe-legis-memo-on…>, he points out that SOPA proposes a system where a single instance of prohibited material could lead to the blocking of thousands of unrelated pieces of content. Internet experts have observed that, beyond being dangerous to innovation, harmful to speech and potentially unconstitutional, SOPA and PIPA are unlikely to work. Countries that block access to prohibited websites by altering the domain name system - as Vietnam does in blocking access to Facebook - find that millions of users are able to circumvent this form of censorship. Millions of Vietnamese users have become Facebook users by entering that site's IP address into their browsers, or configuring their computers to use an uncensored DNS server. It's likely that dedicated US users of The Pirate Bay and other sites will do likewise. Effectively blocking access to sites like The Pirate Bay might require US ISPs to install powerful and expensive "deep packet inspection" software, a cost that would inevitably be passed onto their users. The progress of the bills was slowed in late 2011 by widespread online activism opposing SOPA and PIPA. Hearings are likely to resume early in 2012, and opponents of the bills are facing off against organized lobbying campaigns by the music and film industries who support the legislation. On November 16, 2011, participatory media company Tumblr took strong online action against SOPA, redirecting requests for content on the site to a page that urged users to call US representatives and oppose the bill - their daylong campaign generated more than 87,000 calls to Congress <http://staff.tumblr.com/post/12930076128/a-historic-thing>. Internet community site Reddit plans a site-wide "blackout" on January 18th <http://blog.reddit.com/2012/01/stopped-they-must-be-on-this-all.html> to inform users of the potential harms of SOPA and PIPA. Wikipedia is considering doing the same <http://www.washingtonpost.com/business/technology/wikipedias-wales-wants-to…>. In the spirit of these protests, the MIT Media Lab has linked this blogpost to all our site pages, encouraging anyone interested in the work we do to learn more about SOPA and PIPA. More information and resources follow below. We believe that SOPA and PIPA would make it harder for Media Lab students, researchers and faculty to do what we do best: create innovative technologies that anticipate the future by creating it. We hope you'll join with us in opposing these bills and, if you are a US citizen, in letting your representatives know your concerns about this legislation. - Joi Ito, director, MIT Media Lab *Selected resources on SOPA and PIPA* Liz Dwyer, "Why SOPA Could Kill the Open Educational Resource Movement <http://www.good.is/post/why-sopa-could-kill-the-open-education-resource-mov…>", Good Magazine Julian Sanchez, "SOPA: An Architecture for Censorship <http://www.cato-at-liberty.org/sopa-an-architecture-for-censorship/>", Cato Institute Dan Rowinsky, "What You Need to Know about SOPA in 2012 <http://www.readwriteweb.com/archives/what_you_need_to_know_about_sopa_in_20…>", ReadWriteWeb "Internet Blacklist Legislation <https://www.eff.org/issues/coica-internet-censorship-and-copyright-bill>", Electronic Frontier Foundation, EFF's email campaign against the legislation <https://action.eff.org/o/9042/p/dia/action/public/?action_KEY=8173> and EFF guide to meeting with your representatives <https://www.eff.org/deeplinks/2012/01/stop-blacklist-legislation-guide-pers…>.

Malamud, pubblico dominio e ContendID
by J.C. DE MARTIN Jan. 15, 2012

Jan. 15, 2012

Carl Malamud <https://plus.google.com/102057379055744684863> - 14:57 <https://plus.google.com/102057379055744684863/posts/4oUsLDrgWpR> - Pubblico *Judge Paul Called Me a Thief* /I Was Tried In Abstentia, Convicted and Sent to Copyright School/ It would be wrong for me to call Paul Brownstein a schmuck. After all, I've never met the man! So why is Paul Brownstein calling me a thief? Public.Resource.Org <http://Public.Resource.Org> runs the FedFlix channel, a popular channel with 6,061 videos gleaned from deep inside the vaults of the U.S. government. The International Amateur Scanning League, a group of volunteers based in Washington, D.C., went to the National Archives and found unused videos produced by the government. They send us the DVDs, we rip them and find metadata, and it gets upload to YouTube and the Internet Archive. We've had over 20 million views for these videos. On YouTube, there is a system called ContentID, which allows the owner of video to claim ownership of video or audio. The ContentID system then keeps an eye out for kids uploading the video. The purported owner is then able to take a variety of actions, ranging from simply doing nothing to blocking the display of the video in certain countries, to muting the audio, monetizing the video by forcing advertisements before it plays or as an overlay, or the most extreme action of executing a removal of the offending bits. If the purported owner decides to remove the video because it is in allegedly in violation of copyright, the person who uploaded the offending video gets an Official Copyright Strike on their account. When you get a strike, you have to go to Copyright School, which consists of watching a video about the copyright laws, then taking a test. If you pass the test, and this is only your first strike, your account is put on a kind of probation for 6 months, which means you loose certain powers, such as the ability to designate your videos as Creative Commons licensed so others can use it. If you get 3 strikes on your account, your account is TERMINATED. Public.Resource.Org <http://Public.Resource.Org> has 326 ContentID matches on our account. In many cases, the matches are totally bogus. Using the ContentID Dispute procedure, we're able to submit a brief explanation of why we believe the ContentID match was mistaken, or why this is fair use, or why we have authorization to be using the disputed material. A good summary of these issues and the situation we found ourselves in was printed in the Guardian by Cory Doctorow: http://www.guardian.co.uk/technology/2011/dec/12/pirates-of-youtube-cory-do… After Doctorow's piece appeared, we finished our research on the provenance of the videos, talked to the General Counsel at NARA and at YouTube, and began to systematically dispute many of the matches. You can view our dispute log here: https://public.resource.org/ntis.gov/contentid.html Out of the 326 ContentID matches, as of today we were able to clear 250 of the claims and make them disappear. However, there are still quite a few ContentID matches that no action has been taken on and there is really nothing we can do about it.

questa è una nuova disciplina
by J.C. DE MARTIN Jan. 15, 2012

Jan. 15, 2012

A volte divento impaziente quando colleghi accademici - di varie discipline - si comportano come se pensassero che sulle questioni "digitali" dire la prima cosa che passa loro per la testa sia automaticamente interessante in virtù della loro eccellenza nell'ingegneria, nell'economia, nella filosofia, nel diritto, nella letteratura, nel giornalismo, eccetera. Non è così. Non è più il 1994. Nel 2011 (ma ormai da qualche anno) occuparsi di Internet e di digitale pressupone, se si vuol esser seri, la conoscenza di una bibliografia molto consistente, composta sia da articoli scientifici, sia - e forse soprattutto, con buona pace di coloro che pensano che il libro sia morto - da monografie. Un esempio? Questa recensione dei libri usciti nel solo 2011: http://techliberation.com/2011/12/09/important-cyberlaw-info-tech-policy-bo… Non tutti quei libri sono importanti, ovviamente. Alcuni basterà sfogliarli per cassarli. Altri saranno sufficientemente lontani dai propri specifici interessi - non ci si può occupare di tutto, neanche in questa disciplina emergente! - che si potranno legittimamente ignorare in attesa di avere il tempo di leggere anche quelli. Ma altri libri invece stanno cambiando l'intero settore e il non averli letti squalificherà chi vorrà ancora continuare a occuparsi di Internet in maniera rigorosa. E' così che funziona la ricerca. Da questo punto di vista, anche in Italia dobbiamo sforzarci tutti di alzare l'asticella, di fare ciascuno i propri "compiti", di sudare sulle carte, di tenerci aggiornati. Senza sentirci troppo in colpa se ogni tanto magari ci sottraiamo - il tempo è prezioso - a confronti con persone che pensano ancora di essere nel 1994. juan carlos

Sennett: "The science of getting along"
by J.C. DE MARTIN Jan. 15, 2012

Jan. 15, 2012

E' davvero confortante che col libro di Benkler (e altri, piu' accademici, come quello di Bowles e Gintis), il filone sulla collaborazione si stia espandendo anche negli USA dopo decenni devastati dalla menzogna dell'homo economicus eretto a dogma. jc Sunday, Jan 15, 2012 9:00 AM EST The science of getting along <http://www.salon.com/2012/01/15/how_we_learn_to_play_with_others/singleton> Research shows that our first years of life shape our ability to play well with others. Here's how By Richard Sennett <http://www.salon.com/writer/richard_sennett/> his article is excerpted from the new book "Together: The Rituals, Pleasures and Politics of Cooperation," <http://www.barnesandnoble.com/w/together-richard-sennett/1101996540?ean=978…> from Yale University Press. I'm sure every parent could tell a distinctive story about how their children grew. You might well observe, whatever your own views about children, that learning to cooperate is not easy. That very difficulty is, in a way, positive; cooperation becomes an earned experience rather than just thoughtless sharing. As in any other realm of life, we prize what we have struggled to achieve. The child psychologist Alison Gopnik observes that the human infant lives in a very fluid state of becoming; astonishingly rapid changes in perception and sensation occur in the early years of human development, and these shape our capacity to cooperate. Buried in all of us is the infantile experience of relating and connecting to the adults who took care of us; as babies we had to learn how to work with them in order to survive. These infant experiments with cooperation are akin to a rehearsal, as infants try out various possibilities about getting along with parents and peers. Genetic patterning provides a guide, but human infants (like all young primates) also investigate, experiment with and improve their own behaviour. [...] Continua qui: http://www.salon.com/2012/01/15/how_we_learn_to_play_with_others/ Richard Sennett's works include "The Craftsman," "Respect," "The Fall of Public Man" and "The Corrosion of Character." He taught for many years at the New York Institute of the Humanities and also at the London School of Economics where he is emeritus professor of sociology. He is now a Distinguished Visiting Scholar at the University of Cambridge. More Richard Sennett <http://www.salon.com/writer/richard_sennett/>

Là il y avait un abus manifeste dans l'exploitation commerciale des chefs d'œuvre de Charlotte Perriand. Sinon il y eut de réels abus. Par exemple des éditeurs de cartes postales touristiques ont été poursuivis par les architectes de monuments qui y figuraient. Là les juges ont débouté les plaignants, considérant qu'il s'agissait de vues de l'espace public. Le droit à l'image pose un problème différent. Aujourd'hui, avec la multiplication des téléphones portables pouvant prendre des photos, la loi est inapplicable. Sait-on qu'une des lois scélérates de ces dernières années interdit à un particulier de prendre des photos d'actions répressives de la police ? Le but en est d'empêcher d'apporter la preuve de mensonges policiers... Auparavant, la seule façon pour un tribunal de blanchir la police consistait à refuser la production au procès des preuves du mensonge. Il y eut ainsi à Nice il y a une vingtaine d'années une affaire particulèrement scandaleuse. À l'époque, Internet n'existait pas. Sinon les preuves eussent circulé sur la Toile. Ce qui arrive aujourd'hui pour des documents classés "secret défense" que tout le monde peut consulter sur Internet mais qui ne peuvent être produites devant un tribunal. On a ainsi bloqué le procès des frégates de Taiwan, et par ailleurs interdit la diffusion des preuves accablantes des responsabilités gouvernementales actives dans le génocide du Ruanda (en anglais Rwanda). Étant alors président d'une association internationale de la Francophonie, j'ai eu des informations accablantes de première main. Épouvantable! Enfin la vérité sur l'attentat d'Arusha est ouvertement reconnue depuis peu. Les services spéciaux français avaient pourtant multiplié les trucages. Comme pour l'attentat contre le Rainbow Warrior en Nouvelle Zélande. Comment racontera-t-on l'histoire aux écoliers dans 50 ans ? Encore merci. Gérard Verroust

Copyright Infringement: "the guinea pig"

Copyright Infringement: British Man Faces Extradition To U.S.<http://www.deadline.com/2012/01/copyright-infringement-tv-shack-extradition…> By THE DEADLINE TEAM | Friday January 13, 2012 @ 9:39pm PSTTags: Criminal Copyright Infringement<http://www.deadline.com/tag/criminal-copyright-infringement/>, Richard O'Dwyer <http://www.deadline.com/tag/richard-odwyer/>, TV Shack<http://www.deadline.com/tag/tv-shack/> A 23-year-old British student faces possible extradition to the United States for trial on charges of copyright infringement for hosting a website that pointed visitors to illegal download sites. Richard O’Dwyer’s website TV Shack listed links to other websites where users could access movies and TV shows but did not host any content himself. O’Dwyer, a college student, said he undertook TV Shack as a project to improve his skills and job marketability. O’Dwyer sold $230,000 worth of advertising, which he says was necessary because of the massive server fees. “When you’ve got a website with over 300,000 people a month visiting, there’s a need for infrastructure to support that.” O’Dwyer’s attorney said the young man had done nothing more than Google or Yahoo search engines. Ben Cooper, an extradition lawyer, described O’Dwyer as a “guinea pig” because no British citizen has ever been extradited to the United States for a copyright offense. Nonetheless, a London judge upheld the extradition request and sent it to Britain’s Home Secretary for a final decision. O’Dwyer plans to appeal. http://www.deadline.com/2012/01/copyright-infringement-tv-shack-extradition…
