Mit SpoofStick sehen Sie auf einen Blick, wo Sie ein Link hinführt. Nicht mehr und nicht weniger. Eigentlich sollte diese Information ja auch in der Statuszeile zu sehen, doch

1. ist zumindest bei Windows XP die Statuszeile üblicherweise abgeschalten und
2. gibt es Tricks, wie man Benutzern eine falsche URL vorspielen kann.

Auf der besagten Website gibt's dazu ein interessantes Beispiel. http://signing.ebay.com@10.19.32.4/ führt Sie nicht auf ebay, sondern auf einen ganz anderen Rechner. [ResearchBuzz]

185.175 Übersetzerbau, LU 3 -- die Übung, für die ich den Scanner entwickelt habe.

Das Subforum zur Übersetzerbau LU. Schauplatz wichtiger Diskussionen zur Übung. Beispielsweise gut, um gemeinsam Testfälle zu erarbeiten ;-)
