Student challenges prof, wins right to post source code he wrote for course - Boing Boing - 0 views

  • Kyle's a student at San Jose State University who was threatened with a failing grade for posting the code he wrote for the course -- he wanted to make it available in the spirit of academic knowledge-sharing, and as code for potential future employers to review -- and when he refused, his prof flew into a fury and promised that in future, he would make a prohibition on posting your work (even after the course was finished) a condition of taking his course.
  • The most important lesson from it for me is that students want to produce meaningful output from their course-assignments, things that have intrinsic value apart from their usefulness for assessing their progress in the course. Profs -- including me, at times -- fall into the lazy trap of wanting to assign rotework that can be endlessly recycled as work for new students, a model that fails when the students treat their work as useful in and of itself and therefore worthy of making public for their peers and other interested parties who find them through search results, links, etc.
  • And in this case, it's especially poignant, since Kyle's workflow actually matches the practices of real-world programmers and academic computer scientists: coders look at one anothers' examples, use reference implementations, publish their code for review by peers. If you hired a programmer who insisted that none of her co-workers could see her work, you'd immediately fire her -- that's just not how software is written. Kyle's prof's idea of how computer programmers work is exactly what's meant by the pejorative sense of "academic" -- unrealistic, hidebound, and out-of-touch with reality. Bravo to Kyle for standing his ground!

  • I love learning by making my own mistakes - and that is certainly part of learning to be a decent programmer
  • Or are we to allow that "this is a solved problem, that is a solved problem (read about it here if it helps) but here is a real-world problem that needs research done on it..."
  • Wouldn't it be great if universities once again became places where new knowledge grew and spread from, rather than where it went to be locked up and die?
  • The model of "Trust no-one and write all your code yourself" is outdated. The model of "Trust your fellow humans and write your code with their help" is the future.

The iPad and Information's Third Age | Open Culture - 2 views

  • Though the university initially fought its introduction, the printed textbook provided broad access to information that, for the first time, promised the possibility of universal education.
  • A barrier of symbolic complexity emerged between people and information for one of the first times in history. And the superabundance of information created a world that by necessity had to be divided into smaller and smaller subsections for organizational reasons. As people began to feel increasingly disconnected from information and as its relational and contextual aspects began to fade, we saw a transformation in teaching and learning. Hands-on apprenticeships and small teacher/student cohorts began to disappear, replaced by teachers delivering carefully parsed and categorized information to “standardized” students, all while trapped in classrooms isolated from the world in order to limit “distraction.”
  • It has become virtually impossible for a person to assess the quality, relevance, and usefulness of more information than she can process in a lifetime. And this is a problem that will only get worse as information continues to proliferate. But a quick look at popular technologies shows some of the ways people are working to address it. Social networking leverages selected communities to recommend books, restaurants, and movies. Context- and location-aware applications help focus search results and eliminate extraneous complexity. And customization and personalization allow people to create informational spaces that limit the intrusion of informational chaos.

  • Any genuine solution will have to address the problems of the current informational age — and it will need to continue answering the problems of the previous informational ages. From what I’ve seen, Apple’s new iPad is the first device to promise this (even if that promise isn’t yet fully realized). That is what makes it such a compelling candidate to be the first platform that serves true digital books.
  • Books that are static, don’t allow customization, don’t connect with other information on the device, and don’t leverage social connectivity aren’t the future, no matter how sophisticated the device that serves them. They’re simply the past repackaged.
  • Given what I’ve seen of its features and approaches, the iPad shows the promise to engender such a change, though much development will have to take place for it to realize its potential. Nonetheless, the innovation it offers in three critical areas is especially compelling: accessibility, participation, and customization. Central to all three of these is the fact that the iPad is not a single-use, standalone device; it’s a powerful, converged platform with robust development tools and capabilities.
  • I would argue that the key accessibility feature of the iPad is its apparent “lack” of an interface (a feature Apple’s marketing is working hard to underscore). Unlike all of the other similar devices (including those running Apple’s standard OS), which require users to learn to negotiate complex symbolic interfaces — files, folders, hierarchies, toolbars, navigational buttons — the iPad limits or even eliminates these in favor of touch, an approach intuitive even to those too young to read.
  • The collapsing of symbolic complexity into the simplicity of touch enables participation by new groups of people — even relative technophobes — and this mirrors the increased accessibility offered by Gutenberg’s revolution while lowering the barrier characteristic of most recent technologies.
  • For those interested in culture and creativity, this is an exciting prospect.
  • In Gutenberg’s case, the increase in accessibility led to a dramatic increase in cultural participation, and this is another way the iPad differentiates itself from many of its peer devices.
  • Put in the hands of readers and students, the robust capabilities of its new version of iWork, combined with access to the complete range of apps on the App Store and an entirely new generation of native apps, the iPad could provide access to professional-quality creative tools that empower a new set of participants
  • the iPad’s blend of social and contextual technologies and its ease of customization offer useful ways for the device to help users sort, focus, and control the information around them. The iPad’s networking capabilities, linked to a new generation of digital books, could help people discover both new texts and the members of a discussion group who could help them process what they’re reading. Combined with a portable format that allows readers to carry their books into various contexts, this could be incredibly powerful. One imagines, for example, a field-guide to forests linked to live discussion partners, allowing a reader to discover the forest in a new and engaging way that offers the advantages of both the first and second informational ages. Yet this sort of capability also reveals an area where the iPad falls surprisingly short: its lack of a camera (let alone two, one forward and one backward facing) means the device has limited capabilities for interesting emerging technologies like augmented reality — a staple of recently-developed apps. In terms of future eBooks, a volume of Hemingway that could alert readers that they were only two blocks from the café Les Deux Magots, for example, and offer an augmented tour of the place or that could direct the reader of Brontë to a moor would be transformational indeed. Perhaps we’ll see such capabilities on iPad 2.0.

Social Media in Africa, Part 2: Mobile Innovations - ReadWriteWeb - 0 views

  • social media technology conference PICNIC2008
  • conference featured prolific social entrepreneurs and technology developers from around the world who offered insight into various projects from the African continent.
  • Africa is unique in that it seems to have bypassed the same era of community infrastructure building that has occurred in developed nations around the world.

  • most of the technologies that currently permeate Africa aren't terrestrial. There are very few telephone lines, but mobile penetration is higher than any other region in the world.
  • Instead, internet connectivity is distributed nearly entirely by satellite.
  • The developers who are coming up with solutions in the continent, the ones who are writing software or hacking hardware, are creating for some of the harshest environments and use-cases in the world. If it works in Africa, it will work anywhere."
  • Perhaps this thought is what motivated Google to invest in O3B Networks earlier this month. O3B Networks is an ambitious attempt to bring three billion people in the developing world (mainly in parts of Asia and Africa) online by launching sixteen inexpensive, low-orbit satellites. The potential benefits for Google are obvious. This is three billion new internet users, who will more than likely use Google to search, and who will potentially click-through Adsense links and use other Google products. An indicator that Google may be anticipating as much is their move into Africa last year. They've since opened offices and hired people in both South Africa and Kenya with plans to eventually operate out of all sub-Saharan African countries.
  • At the end of 2007 there were over 280 million mobile phone subscribers in Africa, representing a penetration rate of 30.4% Africa has become the fastest growing mobile market in the world with mobile penetration in the region ranging from 30% to 100% from country to country. Fastest growing markets are in Nigeria, South Africa and Egypt
  • The Democratic Republic of Congo, population 60 million, has 10,000 fixed telephones but more than a million mobile phone subscribers. In Chad, the fifth-least developed country, mobile phone usage jumped from 10,000 to 200,000 in three years.

  • Non-faculty researchers and students are already afforded deposit privileges, and DASH will eventually have collection spaces for each of the 10 schools at Harvard.
  • a pro-open-access policy with an "opt out" clause.
  • Each Faculty member grants to the President and Fellows of Harvard College permission to make available his or her scholarly articles and to exercise the copyright in those articles. In legal terms, the permission granted by each Faculty member is a nonexclusive, irrevocable, paid-up, worldwide license to exercise any and all rights under copyright relating to each of his or her scholarly articles, in any medium, and to authorize others to do the same, provided that the articles are not sold for a profit.

  • Among the many features the DASH development team has added to its DSpace implementation is the ability to link directly from a faculty author's name in DASH search results to his or her entry in Profiles, a research social networking site developed by Harvard Catalyst. Profiles, which provides a comprehensive view of a researcher's publications and connections within the University research community, currently indexes faculty from the medical and public health schools; its developers hope to expand it to include the Faculty of Arts and Sciences and School of Engineering and Applied Sciences in the near future.
  • "DASH is meant to promote openness in general," stated Robert Darnton, Carl H. Pforzheimer University Professor and Director of the University Library. "It will make the current scholarship of Harvard's faculty freely available everywhere in the world, just as the digitization of the books in Harvard's library will make learning accumulated since 1638 accessible worldwide. Taken together, these and other projects represent a commitment by Harvard to share its intellectual wealth."
