I have recently watched a video of a lecture The mystery of the human being, from the ancient times until today. At minute 56 of the video (in German) Prof. Dr. Daum talks about an incident during a marshmallow experiment.

Detailed procedure

During the marshmallow experiment the experimenter presents a marshmallow to a child. The experimenter tells the child that he/she’ll get a second one, if he/she manages not to eat the first one immediately, but is able to wait for a certain amount of time (usually around 15 minutes). The experiment is about the abillity to wait in expectation of a greater reward and to stand the feeling delayed of gratification.

Java: Checked Exceptions Without Throws-clause

Thu, 19 Jan 2017 00:00:00 +0200

Code that potentially throws checked exceptions, is often processed within a try-catch block. Two posibilities exist to forward caught exception to the caller:

Wrap checked exception into an instance of RuntimeException.
Declare a throws-clause

Both may be undesired. This article describes a technice to throw checked exceptions without the need of either. The technique is called throw sneaky. It is implemented as a static method:

Eclipse: Flip arguments using regular expressions

Fri, 09 Sep 2011 00:00:00 +0200

Lately I have migrated a project from JUnit to TestNG. With the help of an Ecplipse plugin this is a one-click task. Every assert-method is replaced by its counterpart in class org.testng.AssertJUnit. This is only an intermediate solution. The final goal is to use org.testng.Assert. This will present a small challenge. JUnit’s two arg assert-methods, e.g. assertEquals or assertSame define order expected, actual. TestNG defines the opposite. Therefore argument order needs to be flipped.
