This is a collection of material that I have used when teaching or giving Workshops about GeoGebra.

Cookies
On July 1:st 2011 the Swedish parliament passed a law which makes it illegal for web pages to set cookies without asking the visitor for permission. The cookie-law stems from an EU Directive which countries like England has deferred for one year to avoid "overnight changes". An example of a web page asking for permission is shown at: EU “Cookies” Directive. Interactive guide to 25th May and what it means for you.
Some notable Swedish out-laws are: The Swedish Parliament (7 cookies), The Swedish Government (2 cookies) and The Swedish Supreme Court (4 cookies).
Until the Swedish parliament has figured out how to implement the new law, I will continue to use the third-party-program which shows the last visitors of this web site on a map (at the bottom of the page), even though this third-party-program uses cookies. In addition to the third-party-cookies, a session cookie is set if the icon for hiding the side menu is clicked. The purpose of hiding the side menu is to make the pages print-friendly.
You can choose to disable cookies in your browser.
