"TWITTER -- February 17, 2011 at 9:30 AM EDT NPR's Andy Carvin on Tracking and Tweeting Revolutions By: Hari Sreenivasan We caught up with NPR's Senior Strategist Andy Carvin between his 400+ tweets a day for a chat about his Twitter stream. It has become a must-follow wire service of sorts for people interested in the latest developments in Tunisia, Egypt and a growing number of countries across the Middle East, Persian Gulf and North Africa. We discussed how he began mapping out whom to trust in the "Twittersphere," and how he works to verify and share facts with NPR as the stories develop. His tweets are populated with the words "source" and "verified?" More often than not, as he re-tweets trends and waves of information across the streams he tracks as his sources verify or discount facts on the ground. Carvin uses a combination of old media (wire services, broadcast networks) and follows a series of bloggers and Twitter accounts. He verifies with sources he trusts before saying a piece of information is "confirmed." Andy has spoken about his open news-gathering processes during a live-chat with Poynter, a Q&A with the Atlantic, the Knight Digital Media Center and it has been blogged about at the New York Times."

"Fair Use, MOOCs, and the Digital Millennium Copyright Act: Frequently Asked Questions In October 2015 the Librarian of Congress issued new rules permitting certain teachers of Massive Open Online Courses (MOOCs) to break encryption on DVDs, Blu-Ray discs and streaming videos to create short clips for use in their teaching. It's a major step forward for MOOC teachers and their students. This document, prepared by Professors Peter Decherney and Brandon Butler, answers some of the most common questions you might have about the new rule."

(Per il contesto, vedi http://infojustice.org/archives/35654 e http://ipclinic.org/2016/01/22/fair-use-moocs-and-the-digital-millennium-copyright-act-frequently-asked-questions/) Parti problematiche: Coursera and Udacity are for profit companies. Can they take advantage of the exemption? Coursera and Udacity are the platforms. Colleges, universities, museums, and other nonprofit organizations offer courses through these platforms. The organization that creates the course must be an accredited nonprofit educational institution, but the provider of the software platform may be for-profit . So a university course offered through Coursera may take advantage of the exemption. How can the material be restricted to students enrolled in the course? We believe that use of passwords provided only to enrolled students will sufficiently limit access to the course content to students or learners. How can redistribution be prevented? Offering streaming rather than downloadable versions of the course content should reasonably limit unauthorized redistribution of the work. Unfortunately, this unfairly disadvantages learners with slower internet access" Cioè l'autorizzazione a far saltare i blocchi anticopia vale soltant per i MOOC che non sono MOOC perché non sono Open ma protetti da password. E l'argomento secondo il quale il fair use vale per i video di corsi Coursera e Udacity, a patto che gli enti che elargiscono il corso non siano a scopo di lucro, anche se le piattaforme lo sono, è dubbio. in effetti Coursera e Udacity traggono profitto dai materiali proposti da questi enti. Quanto all'offerta dei video in solo streaming per impedirne lo scaricamento: almeno nei corsi Coursera dove il link di scaricamento è stato t

Grazie molto interessante, conoscevo e avevo scartato perché a pagamento il parente Camtasia e cerco un alternativa a Jing, fantastico screencpture tool ma limitato come tempi di registrazione e nel formato di destinazione. L'ho taggato su http://pinterest.com/fabriziobartoli/videocasting/ per chi può esser interessato a strumenti simili.

"ELAN is a professional tool for the creation of complex annotations on video and audio resources. With ELAN a user can add an unlimited number of annotations to audio and/or video streams. An annotation can be a sentence, word or gloss, a comment, translation or a description of any feature observed in the media. Annotations can be created on multiple layers, called tiers. Tiers can be hierarchically interconnected. An annotation can either be time-aligned to the media or it can refer to other existing annotations. The textual content of annotations is always in Unicode and the transcription is stored in an XML format. ELAN provides several different views on the annotations, each view is connected and synchronized to the media playhead. Up to 4 video files can be associated with an annotation document. Each video can be integrated in the main document window or displayed in its own resizable window. ELAN delegates media playback to an existing media framework, like Windows Media Player, QuickTime or JMF (Java Media Framework). As a result a wide variety of audio and video formats is supported and high performance media playback can be achieved. ELAN is written in the Java programming language and the sources are available for non-commercial use. It runs on Windows, Mac OS X and Linux. Main other features navigate through the media with different step sizes easy navigation through existing annotations waveform visualization of .wav files support for template documents input methods for a variety of script systems multi-tier regular expression search, within a single document or in a selection of annotation documents support for user definable Controlled Vocabularies import and export of Shoebox/Toolbox, CHAT, Transcriber (import only), Praat and csv/tab-delimited text files export to interlinear text, html, smil and subtitles text printing of the annotations multiple undo/redo Download ELAN"

Il software serve ad annotare video e audio: sembra piuttosto complesso ma è prodotto e offerto dal progetto The Language Archive dell'Istituto Max Plank dei Paesi Bassi, perciò sembra abbastanza sicuro. Ho installato la versione per Mac: poi provo e riporto

"Twitter subtitling is the process of using live or recorded tweets from the backchannel to create subtitles for video content. The use of 'twitter subtitling' has mainly been used to enhance the video archive of live events (e.g. television broadcasts, conferences etc.)."

Come creare una pista di "sottotitoli" per una conferenza o altro evento in diretta a partire dei tweet spediti di chi segue la conferenza, o dal vivo o in streaming.

Bene a sapersi, grazie Claude

La mia recenzione di questo "helpout sugli helpout": "Ronnie was very patient and gave very clear answers. As to whether people from other countries than Australia, Canada, Ireland, New Zealand, U.K., and the U.S. (see https://support.google.com/helpouts/answer/3164468?hl=en&ref_topic=14126 ) would be allowed to offer helpouts in future, he said this is planned. As to the difference between helpouts and hangouts, he explained that though helpouts are using the hangout platform, they are a different service. And when asked if helpout participants can use the live captioning app that can be used in hangouts (see https://hangout-captions.appspot.com/ ), he said no. When I asked why the "Introducing Helpouts by Google" https://www.youtube.com/watch?v=K-VFC9AQM1k video is uncaptioned, and the video embedded in the "Find out what it's like to get a Helpout!" https://helpouts.google.com/111421743141645456280/ls/b41c1faef6b76d0f page is not only uncaptioned, but also uncaptionable via e.g. streaming it to amara.org, because if you try to open it on youtube, you get to https://www.youtube.com/watch?v=picasacid , which says: "An error occurred during validation. This video does not exist. Sorry about that." he candidly said he couldn't answer and suggested using the feedback, which I'm doing. Same reply when I asked if Google planned to caption these videos. Sure, I would have preferred to get more hopeful answers to the questions about accessibility, but it was great to get candid ones, which can now be reported to the discussion lists of the Collaborative for Communication Access via Captioning - http://ccacaptioning.org/ . " No, è vero, Ronnie è stato bravissimo. Chissà quanti helpout si sarà sorbito quel giorno, e paffete arriva una che comincia a rompergli le scatole e il nuovo giocatolo Google, portandolo a riconoscere implicitamente che insomma, meglio gli hangout veri e propri..
