    "Picturing the 1930s," a new educational web site created by the Smithsonian American Art Museum in collaboration with the University of Virginia, allows teachers and students to explore the 1930s through paintings, artist memorabilia, historical documents, newsreels, period photographs, music, and video. Using PrimaryAccess, a web-based teaching tool developed at the university's Curry Center for Technology and Teacher Education, visitors can select images, write text, and record narration in the style of a documentary filmmaker. They can then screen their video in a virtual theater. PrimaryAccess is the first online tool that allows students to combine their own text, historical images from primary sources, and audio narration to create short online documentary films linked to social studies standards of learning, said Glen Bull, co-director of the Curry Center. Since the first version was developed in collaboration with U.Va.'s Center for Digital History and piloted in a local elementary school in 2005, more than 9,000 users worldwide have created more than 20,000 short movies. In creating digital documentaries, students embed facts and events in a narrative context that can enhance their retention and understanding of the material, said Curry research scientist Bill Ferster, who developed the application with Bull. Besides increasing their knowledge about the period, "Picturing the 1930s" enhances students' visual literacy skills, Ferster noted, adding that PrimaryAccess "offers teachers another tool to bring history alive."

  • forecasters have little ability to predict how intense future El Niño episodes will be. According to the National Oceanic and Atmospheric Administration (NOAA) it is also near impossible to pinpoint the exact dates that El Niño will begin.

      Some atmospheric phenomena can be predicted and some cannot.
  • Within the next month more details regarding El Niño and when it will begin will become clearer.

      As more data is collected more patterns may be apparent, and hypotheses can be supported.
  • 90% chance of striking again this year

      I wonder how scientists have come to this claim...

  • damages the agricultural industries in countries surrounding the Pacific Ocean such as Indonesia, and the Philippines.
  • The results of the El Niño events in 1997-1998 were by far the worst in recent history,

      I wonder what happened. I wonder what the effects were.
  • South Asia will likely be hit first with heavy rain and flooding.

      El Nino seems to cause a lot of problems. I wonder what caused scientists to think that all of these were related to El Nino.

    Nice looking Chemistry site. Useful and detailed interactive periodic table. I haven't delved enough into the site but it looks useful.

      Where does this statistic come from?
  • Twitter is a rare case: it has arranged to archive all of its tweets at the Library of Congress.
  • Sometimes when you try to visit a Web page what you see is an error message: “Page Not Found.” This is known as “link rot,”
  • ...14 more annotations...
  • Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,”
  • For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous.
  • According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.”
  • one in five links provided in the notes suffers from reference rot
  • 1961, in Cambridge, J. C. R. Licklider, a scientist at the technology firm Bolt, Beranek and Newman, began a two-year study on the future of the library, funded by the Ford Foundation and aided by a team of researchers that included Marvin Minsky, at M.I.T.
  • Licklider envisioned a library in which computers would replace books and form a “network in which every element of the fund of knowledge is connected to every other element.”
  • Licklider’s two-hundred-page Ford Foundation report, “Libraries of the Future,” was published in 1965.
  • Kahle enrolled at M.I.T. in 1978. He studied computer science and engineering with Minsky.
  • Vint Cerf, who worked on ARPAnet in the seventies, and now holds the title of Chief Internet Evangelist at Google, has started talking about what he sees as a need for “digital vellum”: long-term storage. “I worry that the twenty-first century will become an informational black hole,” Cerf e-mailed me. But Kahle has been worried about this problem all along.
  • The Internet Archive is also stocked with Web pages that are chosen by librarians, specialists like Anatol Shmelev, collecting in subject areas, through a service called Archive It, at archive-it.org, which also allows individuals and institutions to build their own archives.
  • Illien told me that, when faced with Kahle’s proposal, “national libraries decided they could not rely on a third party,” even a nonprofit, “for such a fundamental heritage and preservation mission.”
  • screenshots from Web archives have held up in court, repeatedly.
  • Perma.cc has already been adopted by law reviews and state courts; it’s only a matter of time before it’s universally adopted as the standard in legal, scientific, and scholarly citation.
  • It’s not possible to go back in time and rewrite the HTTP protocol, but Van de Sompel’s work involves adding to it. He and Michael Nelson are part of the team behind Memento, a protocol that you can use on Google Chrome as a Web extension, so that you can navigate from site to site, and from time to time. He told me, “Memento allows you to say, ‘I don’t want to see this link where it points me to today; I want to see it around the time that this page was written, for example.’ ”
