Technical Information

A CALL manager is typically an educator forced to wear on occasion a techie's hat (and we should be thankful that it's not the other way around). Fortunately there exist a number of sites where technical information is readily searchable and available. Here are some which I have found useful (but note that this page has been minimally maintained since 2007):

Server back online Aug 2007: Quick answers to real classroom technology questions. Tech-Ease for Mac <> and Tech-Ease for Win <>.On this date, the portal listed: Internet Getting connected, searching, bookmarks, cookies, plugins, and other Internet mysteries solved.

There are a couple of sites where you can upload files and have them picked up by someone else at a later time. Recipients you specify are sent an email with instructions on how to download the file. Files are removed from the system after 7 days, regardless if they have been picked up or not. You can upload any type of file, mp3, movies, docs, pdfs, and file size might be 100 mbytes or more. Recipients can be anyone with an email address." May 12, 2005

From Today's Headlines from Tuesday, August 14, 2001: 'Web Bugs' Are Tracking Use of Internet

"Many people who have personal Web pages are unknowingly tracking people who visit and sending the information to third parties." This article cites AOL and Yahoo/Geocities as being two web hosts guilty of using 3rd party software that tracks visitors to sites such as this one. When users click events or conceivably even pass something as innocuous as a hit counter, data can be sent to these 3rd party entities. If the same 3rd party is being used by another site, a pattern can be discerned as the user browses from site to site. The practice is exposed here as being inethical because users are not informed that data is being collected on them.
