As a way to enable conversations about wicked problems, IBIS (Issue-Based Information Systems) software seems to have evolved over the past few years. While the academic support of IBIS software has carried an open source license, part of the community has become independent of the university.
For those unfamiliar with how an IBIS might work, Jeff Conklin (at the Cognexus Institute) had done a lot of work on Issues-Based Information Systems (IBIS) based on Rittel and Webber‘s “wicked problems”. The open source software supporting this is Compendium. See the “Limits of Conversational Structure” | Jeff Conklin | April 10, 2008 at http://www.youtube.com/watch?v=pxS5wUljfjE .

As much as I read content from the web — either through a feed reader (I’m currently favouring RssOwl) or a browser (I read with Firefox, and post comments with Flock and Cocomment) — there are times when I want my eyes and hands to be free. I maintain a queue of MP3 audio recordings on a Creative Zen V for listening when walking or driving, and subsequently report on lectures and interview worth noting on the Media Input Queue blog.
The content on this Coevolving Innovations blog is text intensive — people who prefer photos are better to follow the Distractions, Reflections blog — so I have sympathies for readers who find the length tedious.
I was following through on some dialogue on mentoring from Sacha Chua (@sachac) to a blog post by Brian O’Donovan on social software (@bodonovan). I noticed he had a “Listen” button on the entry, so I pressed it … triggering an automated reading of the content in a woman’s voice. This experiment gave me a close-to-perfect reproduction of the text content (and I could guess the meaning of the mispronunciations).
Following through the links, I discovered ReadSpeaker webReader, which originated as a service for the visually impaired. For personal web sites, webSpeaker Free is an ad-supported service (with pre and/or post audio, and banners in the player). It took me less than ten minutes to install on this WordPress blog (as one of the benefits of self-hosting on my own domain).
I noticed that Brian preferred a female voice with a British accent. I’ve tried that, and the American male voice, and somehow find the American female voice the easiest to my ear.

Digital cameras have become so common that they’re often now a feature in mobile phones and audio players. Pressing a button to capture a snapshot of time is so easy. The workflow of storing, printing and sharing those images is complicated. Many would like to return to the days when we would just take the film cartridge out of the camera, and drop it to a photo lab for processing (often in about an hour).
People take more photographs digitally than they did with film cameras. In a six-month study in 2000, when digital cameras were relatively uncommon, subjects (aged 24 to 38) took 200 to 1000 (with an average about 500) photographs, compared to their prior non-digital accumulated collection of 300 to 3000 (with an average of about 1000) pictures (Rodden & Wood 2003). This means that when digital cameras were relatively expensive — and camera phones didn’t yet exist — people were averaging about 1 to 5 photos per day!
People presumably use cameras because they want to be able to retrieve the images later. In a study of 18 parents, the value of long-retrieval of family pictures was high (i.e. around 4.7 on a scale of 5). On experiments of 71 retrieval tasks — finding birthdays, family trips, first pictures of a child, etc. — 61% were successful, taking about 2.5 minutes each. On the 39% of unsuccessful retrievals, subjects gave up after about 4 minutes (Whittaker et al. 2010). This effectively means that, on average, nearly 40% of the digital photos taken last year are lost, and considerable persistence is needed for them to be refound.
Digitalization in photography has replaced trips to the photo lab with the copying of electronic files. Industry standards have stabilized so that image files can be readily copied from cameras to personal computing devices, and onto web servers. Here’s a diagram of some of the activities, platforms and artifacts in digital photography.
Based on this diagram, let me (a) pose some questions for reflection on the choices we implicitly make about managing photos, (b) outline some popular alternatives, and (c) describe the way I do it, myself.

While some of my activity on the Internet is recreational, I continue to play with web tools to learn about the ever-evolving technology. While the average person has become comfortable with e-mail, web feeds are still pretty much a mystery to many. The RSS and Atom specifications first used by newswires has become the principal form of web syndication for blogs and social media.
I’ve recently rearranged my pattern of web use (again). To encourage readers to think about how they use the Internet, let me pose four questions.
With the way that technology continues to evolve, the specific web applications may change … but the pattern should remain the same.
My attitude is reflected in two ideas: (a) open content with attribution, and (b) open platforms with interoperability.
(a) Open content with attribution reflects that I like to share my learning with other people. Posting the content on the Internet improves access and distribution. I understand the workings of copyright — there’s a Creative Commons license on this blog — which means that I retain ownership of my words, on the condition that if someone wants to formally cite the work, he or she should cite me as the source. I’m not an author who makes his living at writing, so simple acknowledgement is normally sufficient.
(b) Open platforms with interoperability means that I don’t want my content inappropriately trapped in places inaccessible to others. I appreciate instances when content should remain private, respecting the needs of others and/or commercial conditions, but secrecy should be the exception rather than the rule. The content should flow freely (i.e. free as in liberty), rather than having to stumble through technological obstacles.
With these principles in mind, I’m reforming the way that I interact on the web. Here’s a diagram (linked to another page in an interactive map).

Photo retouching — with programs such as Photoshop, or the open source clone Gimpshop version of the GNU Image Manipulation Program — can be used to doctor images (sometimes obviously, and sometimes inobviously). I’m more of a programmer than a graphics artists, so I usually just do a quick cropping, resizing and sharpening of my JPEG photographs using Irfanview. This means that the proportions within the image remain the same.
Download Squad pointed out a “next gen image resizing method”, linking to a prior news item about a 4-1/2 minute Youtube video where Shai Avidan demonstrates “Seam Carving for Content-Aware Image Resizing”, for a recent SIGGRAPH conference. It’s fun to watch the video, because it alters images in a way similar to the way human beings do: it keeps the key content (e.g. people) in natural proportion, while removing out some of the uninteresting (or “dead space”) content (e.g. sky).
