PRISM: Open Letter to Cambridge University Press

By Stephen Downes - Stephen's Web. PRISM: Open Letter to Cambridge University Press
Peter Murray-Rust writes an open Letter to Cambridge University Press on the subject of PRISM. "The language of PRISM it implies that publishing in Open Access journals (as I do on occasions) is 'junk science'," he writes. "There is much more from PRISM which is both deliberately factually incorrect and misleading and I cannot see how a reputable scholarly organisation such as CUP could be associated with it." Quite so! Briuan Vickery, from BioMed Central, also attacks the veracity of PRISM. More...

Content-Aware Image Reduction

By Stephen Downes - Stephen's Web. Content-Aware Image Reduction
Traditionally, there were two ways to reduce the size of images. You could either crop them, or you could shrink them (aka 'scaling' them). Each has its disadvantages - when you crop photos, you may cut bits you want to keep, and when you shrink photos, you make the big bits smaller. This video introduces you to 'retargeting', a technique that allows you to keep the things you want to be big, but to just move them closer together. More...

Avatars Without Virtual Worlds: an Alternative Platform

By Stephen Downes - Stephen's Web. Avatars Without Virtual Worlds: an Alternative Platform
Sorry about the unscheduled deliveries of OLDaily this morning. They were the result of unscheduled system reboots while I had the 'send newsletter' window open. I promise that mistakes like this will happen again in the future. Anyhow, how do things like this reach 10 million users before I've even heard of them? Some days I think I'm plugged in, other days I really wonder. Stardoll is a site that lets you create your own doll. Or your own avatar. Bryan Alexander finds this gem: "We spoke with CEO Mattias Miksche in July to discuss the importance of avatars versus virtual worlds, and he emphasized the importance of identity and realism over immersiveness." Which raises the question, do avatars need virtual worlds? And the answer is, of course not. More...

How Facebook's Public Search Listing Could Empower Users

By Stephen Downes - Stephen's Web. How Facebook's Public Search Listing Could Empower Users
Facebook is launching 'public profile' listings, which means that Facebook profiles will be searchable by Google and other search engines. Users can opt to keep their profiles private, though Facebook hasn't exactly been pushing that option. "This move transforms Facebook from being a social network to being quasi-White Pages of the Web," comments Om Malik. I'm wondering whether Facebook is trying to become thre de facto OpenID of the web - in direct competition with OpenID. More...

Are PLEs Low Maintenance?

By Stephen Downes - Stephen's Web. Are PLEs Low Maintenance?
Tom Haskins has posted a number of items over the last few weeks on PLEs. I haven't been linking to most of them because they're mostly just fragments of an idea. But taken collectively they amount to a good discussion. This post links to a number of them (not all of them - he misses this one for some reason). I will have more on all this in the future, but for now, just one comment: 'the middle' of a debate isn't always where you want to be. Because what counts as 'the middle' is too easily manipulated. It's an old political trick - if you want people to adopt, say, a left-wing position, adopt a radical left wing position. This shifts the 'middle' to the left, normalizing the position you want people to adopt. More...

Instructionally Investing in VoiceThread

By Stephen Downes - Stephen's Web. Instructionally Investing in VoiceThread
Wesley Fryer recommends VoiceThread as a way for classes to capture stories and memories. It looks good. But when I look at their example I'm turned off. Couldn't they have explained it without pictures of a whole bunch of soldiers and guns? Also, the website makes it really difficult to read more information; fortunately, Wesley Fryer provides links like this one to VoiceThread in the classroom. More...

Feedshow - A Feed Powered Web Page Presentation Tool

By Stephen Downes - Stephen's Web. Feedshow - A Feed Powered Web Page Presentation Tool
I had thought in the past of writing XSLT to convert RSS to S5. But this example of a working Feedshow shows that it makes more sense just to pipe a feed directly into a player. More...

I Am a Deviant Tool User. You?

By Stephen Downes - Stephen's Web. I Am a Deviant Tool User. You?
More reaction to Gary Stager's take-down of Web 2.0 proponents, most of it not as nice as I was yesterday. Guhlin wonders, "Is Gary's call for us to wake up and do more than rally around the tools REALLY a call to submit to the accepted culture of schools, or one more in line with his point of view?" That was my interpretation, though people like Tom Hoffman suggest that Stager isn't so "bound to traditional schooling." Maybe not, but if the heart of his argument is that the challenge is "to frame the presentation of these tools to teachers in the best thinking about pedagogy," then it seems pretty 'traditional schooling' to me. More: Dave Warlick asks, Web 2.0 is like Logo? James Farmer writes a screamer of a criticism, including a set of (what I now dub) loljabs characterizing Stager's argument. Dean Shareski comments, "personal freedom and empowerment doesn't have to involve schools." Ewan McIntosh wonders why Stager can't find any research when he's read and summarized more than 100 research reports. More...

Sideways Computing

By Stephen Downes - Stephen's Web. Sideways Computing
There seems to be some momentum developing around a programming languaged called Erlang. The logic of Erlang is very different, and I will confess that I don't get it yet (and of course the syntax is sometimes just pointlessly non-standard - cf the notation for comments). A strength of Erlang is (apparently) that it is much better suited to multi-core processors. But I am also sensing that this is where some of the backlash in the Java community is landing. More...

CIHR Introduces New Open Access Policy

By Stephen Downes - Stephen's Web. CIHR Introduces New Open Access Policy
The Canadian Institute for Health Research has announced, formally, its Open Access mandate for all funded research. Peter Suber has coverage. Stevan Harnad notes that it makes CIHR the 31st organization worldwide to do so. It's worth noting that this amounts to "five percent of the world's health research scholarship" - an awful lot, considering the size of our country, and pretty convincing evidence that you do get original research even if you have a public health care system. But it should be noted, as Heather Ross points out, there's a pretty big loophole for publisher embargos. Finally, as Geist says, "It places renewed pressure on SSHRC and NSERC, the other two major granting councils, to at least match CIHR. The same principles apply - taxpayer funded research should be made available to the public that pays the bills and with CIHR now on board, it is now clearly time for the other two councils to adopt open access policies." Quite so, and to that I would like to add my own organization, the National Research Council. We're funded by the people of Canada, our work should be made available to that public. More...
