  • Amazon and the Kindle have the clear lead in the eReader wars. However, numerous competitors to Amazon’s Kindle are cropping up and it’s worth taking a moment to review the state of the art in ePaper.
  • Accessible data visualization in HTML has always been tricky to achieve, particularly because elements such as images allow only the most basic features for providing textual information to non-visual users. A while back, we wrote an article describing a technique we came up with to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element.

  • This is a free software project to help people create printable PDFs from content found on the web. It is a free alternative to HP's Tabbloid service. It is being developed as part of the Five Filters project to promote alternative, non-corporate media.
  • Table below shows the media sites ordered by their time lag on reporting on a story.
    Columns represent:

    * Time lag: number of hours between the time a media site first reported a story and when the story (quote) reached its peak. Negative times mean that site reported the news before it reached its peak, and positive numbers mean that the site was lagging and only reported the news after it reached its peak.
    * Pct of top quotes: Fraction of top stories (quotes) the site covered. The higher the number the more of the important news was covered by the site.
    * Media site: The website of the media that reported on the story.

    For example, -19.5 means that the CNN Political Ticker tends to report a story/quote 19.5 hours before it reaches the peak. And 56 means that the CNN Political Ticker reported 56 out of top 100 most important stories/quotes.
