"Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity." Albert Einstein
"Si nous serrions bien de près notre persuasion la plus chère, nous verrions que ce que nous appelons plus ou moins folie dans les autres, c'est tout ce qui n'est pas purement et simplement notre pensée propre et elle seule, tout ce qui n'est pas moi : fou, c'est le synonyme intime de toi."
( Charles Augustin Sainte-Beuve - Pensées et maximes, p.16, Grasset 1954)
Polyphasic sleep is a term used to describe several alternative sleep patterns intended to reduce sleep time to 2–6 hours daily. This is achieved by spreading out sleep into short naps of around 15–30 minutes throughout the day, and in some variants, a core sleep period of a few hours at night.
The process of adapting to a polyphasic schedule can involve a mentally and physically very difficult one- to two-week transition period, especially for the variant known as Uberman sleep. Thereafter, independent testers claim to experience no apparent drop of cognition or alertness, despite the few hours of sleep attained each day. On the other hand, polyphasic sleep typically requires adhering to a rigid schedule, which makes it unfeasible for many people.
Relatively little scientific research has been performed on polyphasic sleep. Much, if not most, of the information about it comes from the claims of independent testers, many of whom are bloggers.
TypesIn application, "Uberman's sleep schedule" is likely to be the most widely known type of polyphasic sleep, and also the most strict. It consists of six naps of 20–25 minutes each, occurring four hours apart throughout the day. This is also the closest schedule to the type that has been studied by Claudio Stampi in connection with long-distance solo boat races.
"Core sleep" is a variant of Uberman that adds a block of sleep, usually several hours, to the Uberman schedule, replacing one or two naps. (This term is also sometimes used to describe accidental oversleep by someone following Uberman, though one will more likely see the term "crash", and occasionally "reboot".)
Buckminster Fuller advocated "Dymaxion Sleep," a regimen consisting of 30 minute naps every six hours. A short article was published about this schedule in the October 11, 1943 issue of Time Magazine. According to this article, he followed this schedule for two years, but after that had to quit because "his schedule conflicted with that of his business associates, who insisted on sleeping like other men."

Google Web Toolkit (GWT) is an open source Java software development framework that makes writing AJAX applications like Google Maps and Gmail easy for developers who don't speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Java programming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML.

JavaBeans™ is a portable, platform-independent component model written in the Java programming language. The JavaBeans architecture was built through a collaborative industry effort and enables developers to write reusable components in the Java programming language.
With the JavaBeans API you can create reuseable, platform-independent components. Using JavaBeans-compliant application builder tools, you can combine these components into applets, applications, or composite components.
JavaBean components are known as beans. Beans are dynamic in that they can be changed or customized. Through the design mode of a builder tool, you use the property sheet or bean customizer to customize the bean and then save (persist) your customized beans.

ICEfaces is an integrated Ajax application framework that enables Java EE application developers to easily create and deploy thin-client rich Internet applications (RIA) in pure Java. ICEfaces is a fully featured product that enterprise developers can use to develop new or existing Java EE applications at no cost.
ICEfaces is the only RIA framework on the market today that delivers unique Ajax Push capabilities. Discover the power of Ajax Push and create collaborative and dynamic enterprise applications like never before.
ICEfaces leverages the entire standards-based Java EE ecosystem of tools and execution environments. Rich enterprise application features are developed in pure Java, and in a pure thin-client model. There are no Applets or proprietary browser plug-ins required. ICEfaces applications are JavaServer Faces (JSF) applications, so Java EE application development skills apply directly and Java developers are isolated from doing any JavaScript related development.Business objects are objects in an object-oriented computer program that abstract the entities in the domain that the program is written to represent. For example, an order entry program needs to work with concepts such as orders, line items, invoices and so on. Each of these may be represented by a business object.
Business objects are sometimes called domain objects (where the word domain means the business), and a domain model represents the set of domain objects and the relationships between them.
Good business objects will encapsulate all of the data and behavior associated with the entity that it represents. For example, an order object will have the sole responsibility for loading an order from a database, exposing or modifying any data associated with that order (i.e. order number, the order's customer account), and saving the order back to the database.
Business objects don't necessarily need to represent objects in an actual business, though they often do. They can represent any object related to the domain for which a developer is creating business logic. The term is used to distinguish between the objects a developer is creating or using related to the domain and all the other types of object he or she may be working with such as user interface widgets and database objects such as tables or rows.
Data Access ObjectData Access Objects are a Core J2EE Design Pattern and considered best practice. The advantage of using data access objects is that any business object (which contains application or operation specific details) does not require direct knowledge of the final destination for the information it manipulates. As a result, if it is necessary to change where or how that data is stored that modification can be made without needing to change the main application.
Data Access Objects can be used in Java to insulate an application from the underlying Java persistence technology, which could be JDBC, JDO, EJB CMP, TopLink, Hibernate, iBATIS, or any one of a range of technologies. Using Data Access Objects means the underlying technology can be upgraded or swapped without changing other parts of the application.
Disadvantages
The Standard Widget Toolkit (SWT) is a graphical widget toolkit for the Java platform originally developed by IBM and maintained now by the Eclipse Foundation in tandem with the Eclipse IDE. It is an alternative to the AWT and Swing Java GUI toolkits provided by Sun Microsystems as part of the Java standard.
SWT is written in Java. To display GUI elements, the SWT implementation accesses the native GUI libraries of the operating system using JNI (Java Native Interface) in a manner that is similar to those programs written using operating system-specific APIs. Programs that call SWT are portable, but the implementation of the toolkit, despite the fact that it is written in Java, is unique for each platform.
Performance
SWT is designed to be a "high performance" GUI toolkit; faster, more responsive and lighter on system resource usage than Swing. There has been some attempted benchmarking of SWT and Swing, which concluded that SWT is more efficient than Swing, although the applications benchmarked in this case were not complex enough to draw solid conclusions for all possible SWT or Swing uses.

Model-view-controller (MVC) is an architectural pattern used in software engineering. In complex computer applications that present lots of data to the user, one often wishes to separate data (model) and user interface (view) concerns, so that changes to the user interface do not affect the data handling, and then the data can be reorganized without changing the user interface. The model-view-controller solves this problem by decoupling data access and business logic from data presentation and user interaction, by introducing an intermediate component: the controller.
Java Platform, Enterprise Edition
Unlike the other frameworks, Java EE defines a pattern for model objects.
Java Swing is different from the other frameworks, in that it supports two MVC patterns.
EasyMock provides Mock Objects for interfaces in JUnit tests by generating them on the fly using Java's proxy mechanism. Due to EasyMock's unique style of recording expectations, most refactorings will not affect the Mock Objects. So EasyMock is a perfect fit for Test-Driven Development.

In object-oriented programming, mock objects are simulated objects that mimic the behavior of real objects in controlled ways. A computer programmer typically creates a mock object to test the behavior of some other object, in much the same way that a car designer uses a crash test dummy to test the behavior of a car during an accident.
Reasons for use
In a unit test, mock objects can simulate the behavior of complex, real (non-mock) objects and are therefore useful when a real object is difficult or impossible to incorporate into a unit test. If an object has any of the following characteristics, it may be useful to use a mock object in its place:
For example, an alarm clock program which causes a bell to ring at a certain time might get the current time from the outside world. To test this, the test must wait until the alarm time to know whether it has run the bell correctly. If a mock object is used in place of the real object, it can be programmed to provide the bell-ringing time (whether it is actually that time or not) so that the alarm clock program can be tested in isolation.
Use in test-driven developmentProgrammers working with the test-driven development (TDD) methodology make use of mock objects when writing software. Mock objects meet the interface requirements of, and stand in for, more complex real ones; thus they allow programmers to write and unit-test functionality in one area without actually calling complex underlying or collaborating classes[4].
Apart from complexity issues and the benefits gained from this separation of concerns, there are practical speed issues involved. Developing a realistic piece of software using TDD may easily involve several hundred unit tests. If many of these induce communication with databases, web services and other out-of-process or networked systems, then the suite of unit tests will quickly become too slow to be run regularly. This in turn leads to bad habits and a reluctance by the developer to maintain the basic tenets of TDD.
Warning: The following section is opinion: (Section) When mock objects are replaced by real ones then the functionality will need testing again. These are integration tests rather than unit tests, and so, strictly speaking, fall outside of the process of test-driven development.(End Section)
In reality, there is little common agreement agreement on where TDD stops. Story-Driven Development practitioners, for example, consider themselves TDD, and popular TDD methodologies like Test::Tutorial by Michael Scwern[5] make no distinction between unit and integration tests - only between "Programmer" and "Customer" tests. To quote Mike Schwern "Integration tests are still unit tests; the units are just bigger."
JUnit is a simple framework to write repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks.
I'll present the steps to be followed in writing and organizing your own tests using JUnit:
How do you write testing code?
Simple Test Case
The simplest way is as an expression in a debugger. You can change debug expressions without recompiling, and you can wait to decide what to write until you have seen the running objects. You can also write test expressions as statements which print to the standard output stream. Both styles of tests are limited because they require human judgment to analyze their results. Also, they don't compose nicely- you can only execute one debug expression at a time and a program with too many print statements causes the dreaded "Scroll Blindness".
JUnit tests do not require human judgment to interpret, and it is easy to run many of them at the same time. When you need to test something, here is what you do:
@Test public void simpleAdd() {
Money m12CHF= new Money(12, "CHF");
Money m14CHF= new Money(14, "CHF");
Money expected= new Money(26, "CHF");
Money result= m12CHF.add(m14CHF);
assertTrue(expected.equals(result));
} If you want to write a test similar to one you have already written, write a Fixture instead.Tests need to run against the background of a known set of objects. This set of objects is called a test fixture. When you are writing tests you will often find that you spend more time writing the code to set up the fixture than you do in actually testing values.
To some extent, you can make writing the fixture code easier by paying careful attention to the constructors you write. However, a much bigger savings comes from sharing fixture code. Often, you will be able to use the same fixture for several different tests. Each case will send slightly different messages or parameters to the fixture and will check for different results.
When you have a common fixture, here is what you do:
public class MoneyTest {
private Money f12CHF;
private Money f14CHF;
private Money f28USD;
@Before public void setUp() {
f12CHF= new Money(12, "CHF");
f14CHF= new Money(14, "CHF");
f28USD= new Money(28, "USD");
}
} Once you have the Fixture in place, you can write as many Test Cases as you'd like. Add as many test methods (annotated with @Test) as you'd like.Once you have tests, you'll want to run them. JUnit provides tools to define the suite to be run and to display its results. To run tests and see the results on the console, run:
You make your JUnit 4 test classes accessible to a TestRunner designed to work with earlier versions of JUnit, declare a static method suite that returns a test.org.junit.JUnitCore.runClasses(TestClass1.class, ...);
public static junit.framework.Test suite() {
return new JUnit4TestAdapter(Example.class);
}
