this gist describes how to 1. get an OAuth token from Android's AccountManager, 2. use this token to connect with GTalk via XMPP. Blog post about it: http://blog.tomtasche.at/2013/05/gtalk-and-oauth-on-android.html

EinStern is a mixture of routing algorithms like depth-first and dijkstra. it is able to find a path between "things" - points without any distance or similar between each other. Blog post about it: http://blog.tomtasche.at/2013/05/routing-things-and-stuff.html

TomTasche / DoesStringPoolExist.java
Created May 4, 2013 19:42
i had a discussion about the possible existence of a global "String pool" in newer versions of Java. turns out, there is no such thing. however, hardcoded strings are "pooled", i.e. String a and String b in the example are the *same instance of String*.
String a = "test";
String b = "test";
System.out.println("a == b? " + (a == b)); // true
String c = "tester";
String d = a + "er";
System.out.println("c == d? " + (c == d)); // false
