Using Controllers in Play Framework
Author :

Date : Tue Sep 20th, 2011
This chapter will help you to keep your controllers as clean as possible, with a well defined boundary to your model classes. Always remember that controllers are really only a thin layer to ensure that your data from the outside world is valid before handing it over to your models, or something needs to be specifically adapted to HTTP. The chapter will start with some basic recipes, but it will cover some more complex topics later on with quite a bit code, of course mostly explained with examples.

Stochastic Gradient Ascent

Gradient Ascent uses the whole dataset on each update. This is fine with 100 examples but, with billions of data points containing thousands of features, it is unnecessarily expensive in terms of computational resources. An alternative to this method is to update the weights using only one instance at a time. This is known as Stochastic Gradient Ascent. Stochastic Gradient Ascent is an example of an on-line learning algorithm. This is known as on-line because we can incrementally update the classifier as new data comes in rather than all at once. The all-at-once method is known as batch processing.

Core Concepts of the Java Memory Model (JMM)
Author :
ManningPublications
Date : Thu Apr 21st, 2011
The Java Memory Model (JMM) is described in section 17.4 of the Java Language Specification (JLS). This is quite a formal part of the spec and describes the JMM in terms of synchronization actions and the mathematical construct known as a partial order. This is great from the point of view of language theorists and implementers of the Java spec (in other words, compiler and VM makers) but not as good for application developers who need to understand the details of how their multithreaded code will execute.

jQuery effects certainly add fl air, as is evident when we see elements gradually slide
into view instead of appearing all at once. However, they can also provide important
usability enhancements that help orient the user when there is some change on a
page (especially common in AJAX applications). In this chapter, we will explore a
number of these effects and combine them in interesting ways.

Documenting our Application

Date : Tue Aug 25th, 2009
Every developer's favorite task is documenting their application (or so I've heard).
As irritating as documentation can be, delivering a complete solution implies
comprehensive, usable documentation. This goes beyond (but includes) typical
Javadocs. However, more is required in order to understand how a particular
application works, how its parts fi t together, where dependencies lie, and so on. Even
us, the developers, benefi t from having a wide variety of documentation available.

New Features in Java 7.0 - Part 1
Author :
Christy
Date : Mon Feb 23rd, 2009
This article discusses the new features that are available in Java 7.0. Java 7.0 comes with bunch of new features – language level changes as well as API level changes and this article concentrates on the new API features such as Cache API, New Date and Time API and New IO 2 as well as the language level changes in the form of Super packages. The readers are assumed that they are more familiar with the Java 5.0 language level changes such as Generics and Annotations. This article covers few of the new features in Java 7.0 and the remaining set of new features will be covered in the next article. It is likely that the APIs may undergo changes before the formal release of Java 7.0 happens.

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture.
