New open source Semantic Web store from Garlik capable of enterprise scale | The Semantic Web | ZDNet.com

  • An oft-repeated concern in discussing large-scale deployment of Semantic Web
    ideas is that of ’scale.’ With many of the better known data stores upon which
    the Semantic Web depends capable of storing only tens or at best a few hundreds
    of millions of RDF triples, it can be difficult to argue that the technology is
    fit for real-world deployment at scale.


    There are, of course, different ways of managing data, and it’s not always
    necessary to store everything in one massive store… but for those concerned
    about scale today’s news from UK-based Garlik may well put their minds at rest.


    The company has taken their internally developed (and massively scalable) RDF
    triple store and released it to the world under an Open Source license as 4store.

Playpower.org and the open-source educational software revolution - Digital Media and Learning Competition Winners Hub

Derek Lomas wants you to join his open-source educational software revolution. Lomas, along with two other partners, founded Playpower when they realized educators were lacking a rich, open-source developer community. He has fond memories of games like Lemonade Stand, Oregon Trail, and Math Munchers (and points out that some teachers are still using these game in their classrooms). These games were simple, effective, and totally engaging. Playpower would like to bring back the experience of trekking across the planes or building a neighborhood empire out of squeezed fruit. "Teens love these indie games. They get it. And not simply because they are 'retro'." It seems the field is ripe for educators to turn back to development: An audience that loves the style; A platform with restraints (limited graphics, RAM, etc.) that actually benefit the home developer. The only piece missing is a central place where geeky teachers can go to solicit help, learn the language, and share their goods. Playpower wants to develop that place.\n\nLomas' first project is to pull together/create a set of tools for a "$10 computer". That computer, a platform that includes a keyboard with a cartridge slot, a mouse, and two game controllers, runs on an old Nintendo/AppleII processor (which is now in the public domain) and is sold all over the developing world. With a little help from indie coders, Lomas and his partners hope to create an set of tools that would help educators, students, and programmers create new content that would be passed to distributors who would package the games in the computer kits. Sick, I know. So, with all the ingredients in the kitchen, it is just a matter of pulling them together to give new life to these simple machines.\n\nI asked Lomas how the ed tech community could help with Playpower's greater goal. "I think it is important to know the history of educational games." He would like to create an archive of sorts that would include a catalog of ed. games over the past 30 years. This resource would include sni

Open-source software in the recession: Born free | The Economist

  • MANY technology firms are floundering amid the recession. But many of the ones
    that offer services tied to open-source software—free programs written by
    volunteers who collaborate online—are boasting double-digit growth. Sales at Red
    Hat, the world’s biggest independent open-source firm with annual revenues of
    $653m, grew by 18% year-on-year in the first quarter. More and more firms,
    particularly in Europe, seem prepared to embrace open source (see chart).
    “Budgets are tight and we think that is good for open source,” said Jim
    Whitehurst, Red Hat’s boss, when announcing the results.
  • Cost is once again the main reason why companies are turning to open source,
    says Jeffrey Hammond of Forrester Research, a consultancy. Its success is no
    longer limited to basic software, such as Linux or Apache, a program that powers
    web servers. Open-source firms are flourishing in databases (Ingres, for
    instance), business intelligence (JasperSoft), customer-relationship management
    and other business applications (SugarCRM, Alfresco). In addition, open-source
    firms have started to move into new markets without proprietary rivals. For
    instance, a company called Cloudera distributes a version of Hadoop, a program
    which helps firms process and analyse the unprecedented volumes of data
    generated by large websites.

Computing: Unlocking the cloud | The Economist

  • The argument has been won. It is now generally accepted that the future will
    involve a blend of both proprietary and open-source software. Traditional
    software companies have opened up some of their products, and many open-source
    companies have adopted a hybrid model in which they give away a basic version of
    their product and make money by selling proprietary add-ons (see article). The rise of software
    based on open, internet-based standards means worries about lock-in have become
    much less of a problem.
  • The obvious answer is to establish agreed standards for moving data between
    clouds. An industry effort to this effect kicked off in March. But cloud
    computing is still in its infancy, and setting standards too early could hamper
    innovation. So buyers of cloud-computing services must take account of the
    dangers of lock-in, and favour service providers who allow them to move data in
    and out of their systems without too much hassle. This will push providers to
    compete on openness from the outset—and ensure that the lessons from the success
    of open-source software are not lost in the clouds.

  • CLOUD computing may be the
    next big thing, but its politics are as old as the mainframe. Geeks from the
    early years of the information-technology (IT) industry would have had no
    difficulty deconstructing a quarrel that has broken out among IT’s modern
    giants. At issue is an “Open Cloud Manifesto”, which was published on March
    30th.
  • Even before that date,
    accusations were flying around online. What caused the controversy was not so
    much the content, which is vague enough for almost everyone to agree with it.
    The “manifesto” essentially calls for computing firms not to fall back on bad
    old habits by trying to lock in customers as computing becomes a utility,
    generated somewhere on the network (“in the cloud”) and supplied as a service.
    Since there will be many different computing clouds, the manifesto points out,
    customers should be able to move their data and applications easily from one to
    another, and “open” standards, not controlled by one company, should be used
    whenever possible.

Hadoop, Analytical Software, Finds Uses Beyond Search - NYTimes.com

  • ,
    a maker of design software, used it
    to create an online catalog of products like sinks, gutters and toilets to help
    builders plan projects.. The company looks to make money by tapping Hadoop for
    analysis on how popular certain items are and selling that detailed information
    to manufacturers.
