SynchroEdit Web-based Word Processor Allows Multiple Simultaneous Edits
Very interesting synchronous editor. Allowing multiple people to edit a document at the same time has been an intractable problem, and one that affects lots of collaborative editing efforts. Whiteboard-style apps let people draw on the same space, but actual editing has been impossible. Haven't had time to play with this yet, but it's the one new web-based word processor that has caught my eye. [via The Social Software Weblog]SynchroEdit, a browser-based simultaneous multiuser editor
Or, yet another collaborative AJAX word processor. SynchroEdit is focused specifically on multiple simultaneous edits, which pushes it farther toward the SubEthaEdit / JotSpot Live end of the continuum from something like Zoho Writer, which seems more geared towards asynchronous collaborative editing. A couple of interesting features set SynchroEdit apart – the editor window depicts each user’s changes in a different color, so you can clearly see who has edited what, plus the interface marks the area a user is currently editing with a colored flag and their name. These two features would be really handy for knowing both who’s doing what currently, as well as who contributed which bits over time.
The SynchroEdit team has been led by Christopher Allen and Kalle Alm, with backing from Socialtext and the Bainbridge Graduate Institute. It’s in a stable alpha release right now, with plans for a full open source release later this fall.

Acoustical Spying Recovers Passwords With 90-percent Accuracy
Computer scientists at UC Berkeley have been experimenting with recordings of keystrokes. Using 10-minute sound recordings of users typing at a keyboards, researchers were able to feed the data into a computer and recover up to 96 percent of the typed characters. By running the audio repeatedly through a feedback loop that trains the computer, they were able to recover passwords, passphrases, and complete paragraphs. [via FutureEdition from Arlington Institute]Once the system is trained, recovering the text became more straightforward, even if the text was a password and not an English word. After just 20 attempts, the researchers were able to retrieve 90 percent of five-character passwords, 77 percent of eight-character passwords and 69 percent of 10-character passwords.

What was particularly striking about this study, the researchers said, was the ease with which the text could be recovered using off-the-shelf equipment. "We didn't need high-quality audio to accomplish this," said Feng Zhou, a UC Berkeley Ph.D. student in computer science and co-author of the study. "We just used a $10 microphone that can be easily purchased in almost any computer supply store."

Jerry Michalski's Brain is Back Online
PersonalBrain was one of the most advanced personal knowledge tools I ever used. Jerry Michalski has the largest brain in existence and has put it back online after a long hiatus. Jerry's brain is a great example of how these tools can be used, as are David Buchan's Brainwave patterns. [More...]

What is Web 2.0?
The web is a big idea and, for me, Web 2.0 (or 3.0 or 4.0) means weve made a significant step forward in usability and usefulness. Not necessarily new or different (because the web, as conceived, was a really good big idea,) but were doing much of it better and its getting easier to do what we want. [More...]
