The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming.
In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems.
The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own.
The book covers the classical problems, including "Readers-writers", "Producer-consumer", and "Dining Philosophers". In addition, it collects a number of not-so-classical problems, some written by the author and some by other teachers and textbook writers. Readers are invited to create and submit new problems.
Metawidget takes your domain objects and automatically creates User Interface components for them, saving you handcoding your UIs and leaving you to concentrate on stitching together your application.
As much as possible, Metawidget does this without introducing new technologies. It inspects, at runtime, an application's existing back-end architecture (such as JavaBeans, annotations, XML configuration files) and creates components native to its existing front-end framework (such as Swing, Java Server Faces, Struts or Android).
Metawidget does not hide the power of your existing User Interface framework from you and guarantees that your investment in its technology and knowledge is as valid as always. The LGPL open source license allows the use of Metawidget in open source and commercial projects.
JAutodoc is an Eclipse Plugin for automatic adding Javadoc and file headers to your source code. It optionally generates initial comments from element name. Starting with Release 1.3 of JAutodoc it is possible to define Velocity templates for Javadoc and file headers.
