Massive Open Online Courses in the Developing World | MIT Technology Review | education and new media | Scoop.it

"How a teacher in El Salvador became an advocate of massive open online courses, and why hardly anyone listens to him yet.

(...) While MOOCs could be an opportunity to improve education in poor regions, they’re also profoundly threatening to bad professors and to weak institutions."

Difference Engine: The PC all over again?

Difference Engine: The PC all over again? | education and new media | Scoop.it

"WHAT could well be the next great technological disruption is fermenting away, out of sight, in small workshops, college labs, garages and basements. Tinkerers with machines that turn binary digits into molecules are pioneering a whole new way of making things—one that could well rewrite the rules of manufacturing in much the same way as the PC trashed the traditional world of computing."

Open Peer to allow direct peer-to-peer signaling to initiate connection between people, using browsers

Open Peer to allow direct peer-to-peer signaling to initiate connection between people, using browsers | education and new media | Scoop.it

While WebRTC is a protocol that allows direct communication between individuals on the internet, using their browser, there is a bottleneck that needs to be resolved. 

WebRTC does not have a "signaling protocol", which allows the initial contact, the "handshake" between two computers, to be performed without the assistance of a dedicated server.

The trouble is that firewalls are preventing that initial communication from happening. They close your computer within a space that others, on the outside, cannot penetrate.

 

Now there is some important work in progress to establish an open peer-to-peer signaling protocol that will overcome the handshake bottleneck.

More at http://openpeer.org/

 

Open Peer is peer-to-peer signalling protocol taking advantages of the IETF advances of firewall penetration techniques for moving media and adds a layer to performs the media signalling in a peer-to-peer fashion but does expect that a minimal requirement of rendezvous servers existing. Beyond the initial rendezvous to get past firewalls, the servers should drop out of the protocol flow and are no longer required.

 

Open Peer was designed with these main goals in mind...

Research fraud exploded over the last decade

Research fraud exploded over the last decade | education and new media | Scoop.it

"A number of studies have spotted a worrisome trend: although the number of scientific journals and articles published is increasing each year, the rate of papers being retracted as invalid is increasing even faster. Some of these are being retracted due to obvious ethical lapses—fraudulent data or plagiarism—but some past studies have suggested errors and technical problems were the cause of the majority of problems. (...) The authors find that, since 1975, the rate of retracted articles as a percent of total publications has increased nearly tenfold. Duplicate publications and plagiarism, which didn't use to be a significant problem, have boomed since 2005. And while retractions due to errors have increased, those due to fraud have increased much faster"
