PHP-Einfach.de - Base64 kodieren/dekodieren

http://www.php-einfach.de/sonstiges_genera...

Base64 Kodierer Die Base64-Kodierung benutzt man oft, um Binärdaten über Technologien zu übertragen, die 8-bit nicht sauber übertragen können, wie z.B. Emails. Auch verwendet man dieses Verfahren oft wenn bestimmte Zeichen zum Speichern in einem Text nicht vorkommen darf, z.B. Zeilenumbrüche beim Speichern in eine Textdatei.

Quietly Scheming » Fisheye Component v0.3

http://www.quietlyscheming.com/blog/compon...

Fisheye Component v0.3 A few days ago I was idly browsing the web when I ran across a nice little DHTML animation that zoomed in on text as you moved your mouse around it. The effect reminded me of the Fisheye Menus developed by Ben Benderson at the University of Washington. I remember reading about the concept years ago and thought was a great little bit of UI innovation. Well, one thing led to another, and shortly thereafter a Flex component popped out. Try out a demo below… I’ve…

We are investigating techniques to support selection of an item from a long linear list. This issue comes up for data-driven applications, such as e-commerce on the Web where a user must select a country, state, city, service, etc. The primary technique we are looking at is the application of fisheye views to linear lists. The image below shows a snapshot of the fisheye menu. Click on it to try a live demo.

Wie aber bekommt man sprachabhängig einfach nur die typographisch korrekten Anführungsstriche an den Anfang und das Ende des Blockes? Auch hier hilft das Beispiel in der CSS-TR nicht viel weiter.

Apache2: Zugriffskontrolle mit mod_cband Nachdem mein Server heute durch automatisierte Anfragen von Snap.com auf mein Blog quasi lahmgelegt wurde habe ich nun für nodomain.cc mod_cband aktiviert.
