Written by Hortense As someone who has been moderating comments for over two years (and using the internet for about 17), I’ve seen a lot of internet slang fads come and go. But there are some phrases, it seems, that just won’t die: I’m not going to go so far as to say these phrases should be [...]

Written by Nica24 I visit Rosie O’Donnell’s blog almost every day, I enjoy her. I am always amazed at the nasty, sometimes violent reaction she brings out in some people. But I want to pass this on, Rosie printed it on the home page of her blog, it was sent to her. I’m sending it as [...]

I first read about Many Eyes in the business section of the Sunday 8/31/08 NY Times, where it was described by the Times writer Anne Eisenburg, "Lines and Bubbles and Bars, Oh My! New Ways to Sift Data." Eisenburg argues that Many Eyes does for users of data displays what YouTube does for videos and Flickr for photos: "Now they can share more technical types of displays: graphs, charts, and other visuals they create to help them analyze data buried in spreadsheets, tables, or text." Many Eyes was created by IBM scientists and developers to provide sophisticated visualization tools for data analyses and displays. The site should be of interest to students and to instructors, and to the general public. One of the most important contributions of the Web-- beyond quick communications and ready access to information, advice, and opinion-- is the access to sound, video, photo and other tools that were previously the province of specialists. (One caution--because Many Eyes is experimental the server is not always up, sometimes it is closed for development and updating.) ____JH

"Many Eyes is a bet on the power of human visual intelligence to find patterns. Our goal is to 'democratize' visualization and to enable a new social kind of data analysis. Jump right to our visualizations now, take a tour, or read on for a leisurely explanation of the project.
All of us in CUE's Visual Communication Lab are passionate about the potential of data visualization to spark insight. It is that magical moment we live for: an unwieldy, unyielding data set is transformed into an image on the screen, and suddenly the user can perceive an unexpected pattern. As visualization designers we have witnessed and experienced many of those wondrous sparks. But in recent years, we have become acutely aware that the visualizations and the sparks they generate, take on new value in a social setting. Visualization is a catalyst for discussion and collective insight about data.
We all deal with data that we'd like to understand better. It may be as straightforward as a sales spreadsheet or fantasy football stats chart, or as vague as a cluttered email inbox. But a remarkable amount of it has social meaning beyond ourselves. When we share it and discuss it, we understand it in new ways."

I only dabble in software programming occasionally (usually in Python), but I do pay attention to what programmers are doing because I believe the skill of programming is one of the most important achievements of the 20th and 21st centuries. Without programmers our handsome hardware computers would merely be pieces of furniture.
This item is from Jon Udell's blog and reports on a collection of essays compiled by Greg Wilson and Andy Oram, Beautiful Code: Leading Programmers Explain How They Think: "The idea is to get a bunch of well-known and not-yet-well-known programmers to select medium-sized pieces of code (100-200 lines) that they think are particularly elegant, and spend 2500 words or so explaining why."
I believe Udell's book comments on sharing expertise, through Internet video and screencasting, are important beyond the field of programming. The influence of expert minds on one another and the potential influence of expert minds on student minds in formation are highly valuable features of our information age. ____JH

"The 600-page tome arrived recently, and as I’ve been reading it I’m struck once again by the theme of narrating the work. Of the chapters I’ve read so far, three are especially vivid examples of that: Karl Fogel’s exegesis of the stream-oriented interface used in Subversion to convey changes across the network, Alberto Savoia’s meditation on the process of software testing, and Lincoln Stein’s sketches (”code stories”) that he writes for himself as he develops a new bioinformatics module.
Although this is a book by programmers and for programmers, the method of narrating the work process is, in principle, much more widely applicable. In practice, it’s something that’s especially easy and natural for programmers to do.
It’s easy because a programmer’s work product — in intermediate and final form — happens to be lines of text that can be printed in a book or published online.
It’s natural because programmers have been embedded for longer than most other professionals in a work process that’s fundamentally enabled by electronic publishing. We’ve been sharing code, and conversations about code, online for decades.
Most work processes don’t lend themselves to the sort of direct capture and literal representation that you see in Beautiful Code. Not yet, anyway. I think that can and will change, though, and I think two emerging forms of media will be powerful agents of change.
One of those forms is Internet video, which enables the capture and sharing of many kinds of physical-world expertise. The other is screencasting, which does the same for virtual-world expertise. Narration of work in these forms won’t be able to be printed in a book. But it will be just as valuable as the narration in Beautiful Code, and for the same reasons. Access to expert minds is just inherently valuable. We’re entering an era in which we’ll be able to access many more — and many different kinds of — expert minds. I’m looking forward to it. Meanwhile, I’m enjoying the access I have now to the 38 minds that Greg and Andy have collected for this book."

David Wiley announces the startup of Open Education News. This is another site to add to your list of rss feeds to monitor happenings in the field of open education. ___JH

"The young field of open education is gaining momentum and energy. As additional projects, foundations, universities, and other participants join the movement, the need increases for a single source to gather, sort, analyze, synthesize, and disseminate news related to open education. As a field, open education is now where the field of open access was a few years ago. Peter Suber's wonderful Open Access News provides an invaluable service to the OA community, and we intend to replicate this service with Open Education News."
"Open Education News is essentially a group blog. A number of individuals from the US, South Africa, and eventually other locations daily monitor the internet for news related to open education. We then aggregate these items and publish them individually with minor commentary. Occasionally we'll publish bigger pieces of our own authorship; analyses and such. If you know of some open education news we should write about, contact David Wiley at david.wiley@gmail.com."
"Open Education News is graciously supported by the Open Society Institute and the Shuttleworth Foundation."

Inside Higher Ed reports on Blackboard's latest loss, which is good news for universities and colleges who use open source software because we can be sure that despite their disclaimers, Blackboard would certainly move against open source courseware if they succeed against Desire2Learn and other private companies. Blackboard's loss is also an affirmation of common sense since anyone with long-time experience in course management software knew that Blackboard's patent claims were simply assertions, not valid original contributions to courseware delivery methods. ____JH

"Both companies appealed the parts of the case they'd lost to the U.S. Court of Appeals for the Federal Circuit, which has nationwide jurisdiction over U.S. patent claims. Its highly technical decision upheld the lower court's conclusion that Blackboard's claims 1-35 were invalid. But the three-judge panel rejected the lower court's finding that Blackboard's patented learning system had originated the approach of giving a single user with a single log-in multiple roles, such as being a teacher in one course and a student in another."
"The appeals panel embraced Desire2Learn's argument that such technology existed in 'prior art,' in this case previously existing course management systems such as Serf and CourseInfo 1.5. The appeals court essentially ruled that the lower court judge had framed Blackboard's claim incorrectly for the jury, said Bruce T. Wieder, a lawyer for the Washington firm of Dow Lohnes who was not involved in the case. Having done so, the Federal Circuit court "could have said, 'This is how you should have interpreted it, you go look at it again,' " Wieder said. "But instead, the court said, 'Since we've seen what was argued, we now can say that the district court wouldn't have come to any conclusion,' and declared those claims invalid."
