"Retrieving legacy files As the old dropbox knew no separation of files by assignment (one of its major limitations), it was not possible to move these files into assignments during the upgrade, and there is no storage area facility available into which they could have been moved, so they are not directly accessible within the application after an upgrade or in courses restored from earlier versions. The old dropbox code used Perl, which has been completely removed from the web application in release 9, so the dropbox cannot be accessed anymore to retrieve the legacy files. A rudimentary Java-based interface is being provided to enable each user individually to download any legacy files they may wish to retrieve. These files can then be submitted in newly created assignments as desired or stored in one's Virtual Hard Drive inside the Blackboard Content System, if that is licensed by the institution and enabled by the system administrator. Unfortunately this interface is not exposed via any link in the application. System administrators or helpdesk staff can however make available such a link to their users, either assisting them with file retrieval on an individual basis or by publishing the download link to their users, e.g. in a system announcement. Community Engagement license holders may also wish to add an HTML portal module with this link, thus simplifying the download process, or add it as external link to the tool panel (in the portal menu column). The location of this interface (relative to your server root) is: /webapps/blackboard/execute/ddb It is important to note that this is not a file system location. You actually have to access the URL via a web browser! Sample HTML for a portal module named something like "Digital Dropbox Download": Download your digital dropbox files here When a user accesses this link, he will either see a message that no files were found for him, or a list of courses in w

SweetSearch came about as the byproduct of making findingDulcinea, an aggregator that terms itself the "Librarian of the Internet." It's a database of about 35,000 web sites vetted by researchers, librarians, and teachers, with priority given to spots like the Library of Congress, Smithsonian, and other public and academic sources. It sweeps away the pseudo-science, forums, and sites that read like paraphrased summaries.
