Open Muffin – Collaborative 3D Animation Shorts

Februar 18th, 2010

Jeder der Freude an OpenSource und “Collaborative 3D Animation” hat sollte sich diese Möglichkeit bei einem entstehenden Projekt mitzuarbeiten nicht entgehen lassen!

Hi!

Ich möchte euch kurz unser Projekt vorstellen: Muffin Animation Shorts

Dabei geht es um das gemeinschaftliche Erstellen eines 3D Animation Shorts. Die grundlegende Idee ist, dass jeder der Lust hat einen kleinen Teil der Produktion übernehmen kann und somit einen Teil zum ganzen beiträgt. Am Ende soll sich die Zusammenarbeit bezahlt machen und eine klasse Animation dabei entstehen.

Die Gemeinschaft wird dabei von Beginn an bestimmen, in welche Richtung es geht. Die erste Aufgabe ist es eine passende Story für die Animation zu entwickeln (vorläufige deadline: 27. jänner), also startet schonmal eure Schreibmaschinen :)

Es würde mich sehr freuen Beiträge und Feedback von euch zu erhalten. Ihr findet die Homepage und das Forum hier:
http://openmuffin.net
http://forum.openmuffin.net

Danke für eure Aufmerksamkeit!

P.S.: Erzählt auch euren Freunden vom Muffin und bleibt informiert per Twitter, RSS und der Facebook gruppe.

.htaccess und .htpasswd Generator mit Flex3

Dezember 6th, 2009

Da es lästig ist immer wieder .htaccess und .htpasswd Dateien zu erstellen hab ich heute einen htaccess Generator in Flex3 erstellt. Eigentlich keine schwere Aufgabe hatte ich gedacht, bis ich festellen musste dass die nötige crypt(3) Funktionalität in der adobe corelib nicht enthalten ist und sich die as3crypto Bibliothek in meiner Entwicklungsumgebung (FlashDevelop 3.0.5) nicht kompilieren lässt.

Nach einigem Probieren klappte dann zwar das Kompilieren der as3crypto, jedoch war das Ergebnis der Code-Erstellung nicht so wie erhofft.  Hier übrigends der Fehler der beim Kompilieren der as3crypto aufgetreten ist:

Warning: flex2.compiler.as3.SignatureExtension.SignatureGenerationFailed[node='ForStatement', level='warning', cause='flex2.compiler.as3.SignatureAssertionRuntimeException: Unreachable Codepath

Die Lösung für das Problem war schließlich die Nachimplementierung eines crypt(3) Javascripts in AS3.

Der Generator benötigt drei Eingabe-Daten:

  • den Benutzernamen
  • das gewünschte Passwort
  • den Pfad zu dem Ordner in dem später die .htpasswd abgelegt wird

Und so sieht sieht das fertige “Produkt” aus

	 *  This Javascript allows you to calculate the encrypted      *
	 *  password generated by the UNIX function crypt(3) on your   *
	 *  computer without using an online script in PHP, PERL,      *

	 *  you need make in this are in function dP(), which is right *
	 *  below the end of this comment.  Refer to the directions    *
	 *  there for details.                                         *

	 *  First and foremost, I thank John F. Dumas for writing      *
	 *  jcrypt.java, a Java-based implementation of crypt(3) and   *
	 *  from which this Javascript is heavily based (actually, I   *
	 *  just did a direct port from his code, using Sun's tutorial *
	 *  and my knowledge of Javascript).  I additionally thank     *
	 *  Eric Young for writing the C code off which Dumas based    *
	 *  his script.  Finally, thanks goes to the original writers  *
	 *  of crypt(3), whoever they are.                             *
	 *                                                             *
	 *  If you have questions, I suggest you ask John Dumas about  *
	 *  them, as I have no real idea what any of this code does.   *
	 *  Base the questions off his source code, as Javascript and  *
	 *  Java are (in basic operators) nearly identical.            *
	 *                                                             *
	 *  jcrypt.java source code can be found at:                   *

Da ich immer wieder Dinge mache die ich Monate später wieder brauche, (mich dann aber nicht mehr erinnern kann wies nochmal genau ging oder wo es zu finden war), hab ich hier mal einen “Blog” eingerichtet um eben solche Dinge zu dokumentieren.
