Subject: Master's Degree Is New Frontier of Study Online Message-ID: <p0624080ece38d0296579@[]> Master's Degree Is New Frontier of Study Online By TAMAR LEWIN August 17, 2013 Next January, the Georgia Institute of Technology plans to offer a master's degree in computer science through massive open online courses for a fraction of the on-campus cost, a first for an elite institution. If it even approaches its goal of drawing thousands of students, it could signal a change to the landscape of higher education. >From their start two years ago, when a free artificial intelligence course from Stanford enrolled 170,000 students, free massive open online courses, or MOOCs, have drawn millions and yielded results like the perfect scores of Battushig, a 15-year-old Mongolian boy, in a tough electronics course offered by the Massachusetts Institute of Technology. But the courses have not yet produced profound change, partly because they offer no credit and do not lead to a degree. The disruption may be approaching, though, as Georgia Tech, which has one of the country's top computer science programs, plans to offer a MOOC-based online master's degree in computer science for $6,600 - far less than the $45,000 on-campus price. Zvi Galil, the dean of the university's College of Computing, expects that in the coming years, the program could attract up to 10,000 students annually, many from outside the United States and some who would not complete the full master's degree. "Online, there's no visa problem," he said. The program rests on an unusual partnership forged by Dr. Galil and Sebastian Thrun, a founder of Udacity, a Silicon Valley provider of the open online courses. Although it is just one degree at one university, the prospect of a prestigious low-cost degree program has generated great interest. Some educators think the leap from individual noncredit courses to full degree programs could signal the next phase in the evolution of MOOCs - and bring real change to higher education. ... http://www.nytimes.com/2013/08/18/education/masters-degree-is-new-frontier-of-study-online.html

Subject: Play voice message after answering phone? Message-ID: <6nub19dfh2ahkqgvmgkk9pvjju741ql63c@4ax.com> Hello Using the AT commands, I'd like to know if it's possible for a voice modem to play a message *after I answered a call by picking up the handset*, with the handset and the modem plugged into the same analog line. http://en.wikipedia.org/wiki/Voice_modem_command_set Or is it only possible if the modem takes the call first? Thank you.

Subject: How Laura Poitras Helped Snowden Spill His Secrets Message-ID: <p06240810ce38d103988d@[]> How Laura Poitras Helped Snowden Spill His Secrets By PETER MAASS August 13, 2013 This past January, Laura Poitras received a curious e-mail from an anonymous stranger requesting her public encryption key. For almost two years, Poitras had been working on a documentary about surveillance, and she occasionally received queries from strangers. She replied to this one and sent her public key - allowing him or her to send an encrypted e-mail that only Poitras could open, with her private key - but she didn't think much would come of it. The stranger responded with instructions for creating an even more secure system to protect their exchanges. Promising sensitive information, the stranger told Poitras to select long pass phrases that could withstand a brute-force attack by networked computers. "Assume that your adversary is capable of a trillion guesses per second," the stranger wrote. Before long, Poitras received an encrypted message that outlined a number of secret surveillance programs run by the government. She had heard of one of them but not the others. After describing each program, the stranger wrote some version of the phrase, "This I can prove." Seconds after she decrypted and read the e-mail, Poitras disconnected from the Internet and removed the message from her computer. "I thought, O.K., if this is true, my life just changed," she told me last month. "It was staggering, what he claimed to know and be able to provide. I just knew that I had to change everything." Poitras remained wary of whoever it was she was communicating with. She worried especially that a government agent might be trying to trick her into disclosing information about the people she interviewed for her documentary, including Julian Assange, the editor of WikiLeaks. "I called him out," Poitras recalled. "I said either you have this information and you are taking huge risks or you are trying to entrap me and the people I know, or you're crazy." The answers were reassuring but not definitive. Poitras did not know the stranger's name, sex, age or employer (C.I.A.? N.S.A.? Pentagon?). In early June, she finally got the answers. Along with her reporting partner, Glenn Greenwald, a former lawyer and a columnist for The Guardian, Poitras flew to Hong Kong and met the N.S.A. contractor Edward J. Snowden, who gave them thousands of classified documents, setting off a major controversy over the extent and legality of government surveillance. Poitras was right that, among other things, her life would never be the same. ... http://www.nytimes.com/2013/08/18/magazine/laura-poitras-snowden.html
