Des pépites du cinéma à télécharger gratuitement et... légalement - Multimédia Près de 5000 films tombés dans le domaine public sont en téléchargement sur le site archive.org. Une alternative à Megaupload, pour regarder en toute conscience des chefs-d'oeuvre du cinéma. Constituer une gigantesque bibliothèque numérique mondiale qui répertorie tous les films, images, musiques, qui appartiennent au domaine public, c'est l'objet de l'Internet Archive (IA). Une nouvelle Alexandrie, encore plus grande, plus ambitieuse et, car elle a tiré des leçons de l'histoire, déclinée en double au cas où une catastrophe devait advenir. Dans cette gigantesque collection, on retrouve plus de 87 milliards de versions archivées (snapshots) du World Wide Web, plus de 500.000 vidéos, 1.000.000 d'enregistrements audio, dont 92.000 de concerts, 3.000.000 de livres et 36.000 logiciels. En comparaison, les serveurs de Megaupload stockaient près de 25 pétabytes de données. Pour les cinéphiles, c'est une véritable caverne d'Ali Baba.

About this Study Twitter has become a new way to communicate with world leaders and a way for these leaders to communicate with each other. On the one hand it allows heads of state and government to broadcast their daily activities and government news to an ever-growing audience, on the other, it allows citizens direct access to their leaders. Anyone can @mention a world leader on Twitter. Whether the world leader answers is another question, although a select few do actually reply to their followers’ @mentions. Two thirds of all world leaders on Twitter Presidents, prime ministers or their institutions in 125 countries have a presence on Twitter. Barack Obama Superstar More important than the number of followers are the connections between these world leaders. Twitter is sometimes used by small nations to put them on the world map and tweet eye-to-eye with their peers. Barack Obama follows a record 676,247 tweeps. Are they tweeting themselves?

TwitLonger — When you talk too much for Twitter Open as in door or open as in heart? #mooc A note on the end of Steve Carson’s post about MOOCs and the liberal arts prompted a brief conversation about the two different meanings of “MOOC” with Brandon Muramatsu. Steve’s original post drew (based on his conversation with Brandon) a distinction between the Edx/Coursera/Udacity “MOOCs” and the Change11/ds106/wileyMOOC “MOOCs” – he suggested using MOCs as a description of the former (as they are not, in the strictest sense, open). But Brandon felt, on reflection, that the real distinction concerned how massive the courses were. As a primer for those of you who read this but don’t live it (you lucky people!) MOOC stands for “Massively Open Online Course”, basically a big global chunk of online learning that doesn’t cost you (the learner) any money. It’s the big noise in university-level education as it’s got that game-changing disruptive innovation feel about it right now. So – for your first version above you could see something like: Some courses are open as in door. (Un)related

Mitt Romney fake Twitter followers: Who's buying them? Screenshot As of last Friday, Mitt Romney’s Twitter account had about 690,000 followers. That’s more than you or me (oh, hush, John Dickerson), but it’s a paltry number compared to that of Romney’s opponent: @BarackObama boasts some 18 million. On a typical day in the past month, Romney’s Twitter account has gained 3,000 to 4,000 new followers, according to Zach Green, whose blog 140elect.com tracks campaign-related Twitter trends. So when Romney’s follower count began growing by the thousands on Friday evening, Green took notice. In a post titled, “Is Mitt Romney Buying Twitter Followers?” Liberals on Twitter jumped on the case, noting that many of Mitt’s new fans appeared to be fake—spambots, pornbots, and accounts set up purely to inflate other accounts’ follower count. Was Romney’s campaign buying Twitter followers? In Romney’s case, though, the apparent spike in fake followers has seemed to delight his opponents, while offering little benefit to his campaign.

L’emballement médiatique à l’ère de Twitter : toujours plus sur toujours moins de sujets Trois jeunes élèves ingénieurs de l’école des Mines se sont penchés sur l’impact de Twitter sur l’écosystème de l’information. Dans un article qu’ils viennent de faire paraître dans la Gazette des Mines ( et qu’ils m’autorisent à reproduire ci-dessous, Nicolas Govillot, Nicolas Manquest et Dimitri Petrakis mettent en évidence l’effet de concentration produit par Twitter: un nombre plus restreint de sujets captent l’attention médiatique de manière plus intense. En résumé: moins de sujets font plus de bruit. Ils détaillent ci-dessous leur méthode de travail pour en arriver à cette conclusion et soumettent le résultat et les (éventuelles) conséquences de leurs recherches à votre sagacité. Philippe Couve Le flux de l’information est incessant. Sortir des définitions moralisatrices de l’emballement médiatique L’UBM de Kantar Media mesure la présence médiatique d’un sujet sur une période donnée, le plus souvent sur une journée. Notes:

How Should Your University Respond to edX? The first thing we should all do is encourage discussion about edX. This is big, important,and exciting news. Faculty get excited about ideas, and the edX announcement contained some great ones. Connecting massively online open education to research into effective pedagogy and use of digital technology for all learners (including face-to-face and blended) is very exciting. The press release notes that: "MIT and Harvard will use the jointly operated edX platform to research how students learn and how technologies can facilitate effective teaching both on-campus and online. So edX is a terrific opportunity to engage the campus community in a discussion what comes next in higher ed, and how we can leverage the affordances of a digital, networked world in our strategic planning. The second thing we do is refrain from all of us jumping on the MOOC / edX bandwagon. The question we all need to ask ourselves are: Any investment should be judged on the impact against all three of these goals.

Twitter May Have 500M+ Users But Only 170M Are Active, 75% On Twitter’s Own Clients Yesterday Paris-based analytics firm Semiocast noted that Twitter had passed the 500 million user account mark, with some detail on how that is playing out on a country-by-country basis. Today, we have some numbers that spell out what that actually means in terms of active Twitter users. Paul Guyot, the founder of Semiocast, says its analysis indicate that on average, less than one-third, 27%, of Twitter’s user base is active — in other words, only around 170 million people, and possibly less at the moment. The numbers come from research Semiocast conducted earlier this year, Guyot notes. Also: active in this sense means the number of accounts that were modified over a three-month period, including changes of avatar, subscribing to a new follower or tweeting, says Guyot.

Quel est le bon timing pour vos tweets, mails et posts Facebook ? Selon la journée et l’heure, les performances d’une mise à jour sur Twitter et Facebook ou encore de l’envoi d’un mail peuvent varier fortement. Avec les réseaux sociaux, il est important de tester différents timings afin de voir ceux fonctionnant le plus auprès de votre communauté. Une récente étude d indique les meilleures journées pour toucher son audience en fonction du média choisi… L’idée principale qui ressort de cette étude est qu’il est souvent plus efficace de poster pendant les périodes creuses (en termes de publication d’informations). En postant, par exemple, le samedi ou le dimanche sur votre blog, sur Facebook et par mail, les retours seront bien meilleurs. Twitter réagit légèrement différemment. Bien sur ces statistiques sont à prendre avec des pincettes puisque selon la thématique de votre site et selon son audience, les résultats varieront. que j’utilise depuis quelques mois peut vous aider dans cette tâche.

OER UCT Project | Centre for Educational Technology The OER UCT project, currently run in the Centre for Educational Technology at UCT with the support of the Shuttleworth Foundation, aims to showcase the teaching efforts of UCT academics by encouraging the publication of resources as OER. Offering new visibility for teaching materials and global individual profiling on international OER sites, a directory listing the UCT Collection of OER went live in February 2010. We'd like your resources to be included here, so join the global move to share, remix, improve and redistribute your teaching resources. What is OER? The term 'open educational resources' (OER) was first adopted at the UNESCO 2002 Conference on Open Courseware for Higher Education in Developing Countries and is now commonly used to refer to an Internet-driven worldwide community effort through which educational resources can be accessed free of charge across the globe.
