Book Flipping Scanning (via spectrummag)
“Jak informuje serwis IEEE Spectrum, rozwiązanie większości powyższych problemów znalazł profesor Masatoshi Ishikawa, który wraz z kolegami z uczelni postanowił wykorzystać do skanowania książek kamerę wideo, rejestrującą obraz z prędkością 500 klatek na sekundę. Urządzenie zamontowane jest na specjalnym statywie - wystarczy umieścić pod nim książkę, a następnie ją błyskawicznie przekartkować.
Kamera rejestruje wszystkie strony, następnie specjalne oprogramowanie obrabia stworzone w ten sposób pliki graficzne o rozdzielczości 1280 x 1024 pikseli - tak, by można było je przeanalizować za pomocą oprogramowania OCR (oryginalne pliki są zbyt mocno zniekształcone). Ishikawa zapewnia, że obecnie operacja zeskanowania 200-stronicowej książki nie trwa więcej niż minutę, ale niewykluczone, że w przyszłości cały proces da się jeszcze skrócić.”

Social Media ROI Examples & Video (reblogged)
I always want to say “Show me the numbers” (money?) when I’m reading stuff about “Social Media Revolution” (or “Social Media Hype” if you preffer). So here it is!!! Great post http://viganunu.tumblr.com/post/497832739/social-media-roi-examples-video
Confessions of a Converted Lecturer: Eric Mazur
Eric Mazur: “I thought I was a good teacher until I discovered my students were just memorizing information rather than learning to understand the material. Who was to blame? The students? The material? I will explain how I came to the agonizing conclusion that the culprit was neither of these. It was my teaching that caused students to fail! I will show how I have adjusted my approach to teaching and how it has improved my students’ performance significantly.” Eric Mazur is the Balkanski Professor of Physics and Applied Physics at Harvard University. An internationally recognized scientist and researcher, he leads a vigorous research program in optical physics and supervises one of the largest research groups in the Physics Department at Harvard University.
It looks like a pretty cool lecture to watch. A few people recommended me this so I decided to share with you.
What do we do with that free time? Mostly we panic and we spend it watching TV.

- Clay Shirky Web 2.0 Expo on the Participatory Web Absolutely my favourite presentation about web and collaboration. This thought reminded me about famous “Stop watching fucking Lost!” from Gary’s Vaynerchuk speech Do what you love (no excuses!).

Seth Godin: Quieting the Lizard Brain
“What you do for a living is not be creative, what you do is ship,” says bestselling author Seth Godin, arguing that we must quiet our fearful “lizard brains” to avoid sabotaging projects just before we finally finish them.
Think you should be webcasting your conference but need proof it is worth it? The Games+Learning+Society Conference has been webcasting its annual event for five years and has six different reasons why streaming their presentations online is no longer a nice to have.
The Society knew there was a broader audience for their conference content than the people who attended on-site. So while webcasting began as a way to take the conference to people who couldn’t attend, find out why the session webcasts have now become a vital resource for both on-site and online attendees as well as presenters.
Sean Michael Dargan, Conference Coordinator, will reveal:
• The six lessons they’ve learned after webcasting 5 different conference events
• How capturing more is better than webcasting less
• Why he’s confident webcasting will never cannibalize his attendance
• What to look for in a webcasting service provider
• How they decide what to record
• Their thought process for when to make sessions publicly available vs. secure vs. paid-only access
