Sage can make 3D plots for visualizing functions of two variables, as well as parametric plots that create three-dimensional surfaces. It also has a variety of tools for making two dimensional representations of three-dimensional surfaces.
In this article by Craig Finch, author of Sage Beginner's Guide, we will make interactive 3D plots of functions of two variables.Read Sage: 3D Data Plotting in full
Results matter, whether you are a mathematician, scientist, or engineer. The time that you spend doing tedious mathematical calculations could be spent in more productive ways. Sage is an open-source mathematical software system that helps you perform many mathematical tasks. There is no reason to compute integrals or perform algebraic manipulations by hand when software can perform these tasks more quickly and accurately. In this article we will take a look at some tips and tricks for working with Sage and using Python more effectively.Read Sage: Tips and Tricks in full
From the very beginning, it was clear that Sakai needed to exist in universities at enormous scales, supporting hundreds of thousands of students. With requirements changing and evolving, and ever-increasing user expectations, Sakai had to be able to connect with a multitude of external systems. When Sakai was designed, the specifics of the majority of the connected systems were not knowable. To adapt to these tough circumstances, Sakai supplies web services that are easy to hook into or to write. Sakai exposes services for creating and maintaining users, sites, and groups. These services are easily extensible to include any part of the Sakai framework.
In this two-part article by Alan Mark Berg and Michael Korcuska, we will look at the two main types of web service, SOAP (Simple Object Access Protocol) and Representational State Transfer (REST) (http://microformats.org/wiki/rest). We will cover already-existing web services and describe how to hook into them. If you follow the examples, you will be able to write and deploy your first service. Lastly, this article includes a few simple client-side Perl scripts that create new users using both the SOAP and RESTful approaches.Read Sakai Web Services: Connecting to the Enterprise (Part 1) in full

Spring Python offers a clean cut way to take simple applications and split them out between multiple machines using remoting techniques that can be seamlessly injected without causing code rewrite headaches. Spring Python makes it easy to utilize existing technologies, while also being prepared to support ones not yet designed.
In this article by Greg Lee Turnquist, author of Spring Python 1.1, we will learn how:
- Pyro provides a nice Python-to-Python remoting capability to easily create client-server applications
- Spring Python seamlessly integrates with Python so that your application doesn't have to learn the API
- You can convert a simple application into a distributed one, all on the same machine
- It takes little effort to rewire an application by splitting it up into parts, plugging in a round-robin queue manager, and running multiple copies of the server with no impact to our business logic
The standard setup of the Scalix server may be satisfactory for most installations, but if you are running Scalix on an internet site or if your local server is available from the Internet, extended security measures have to be taken. In this article by Markus Feilner, we will deal with several recommendations that make your Scalix server safe—like minimizing the number of services running and listening. We will set up a firewall which allows the Scalix users to connect to. After that, we will set up Stunnel to provide SSL-encrypted Scalix services. Then, we will use OpenVPN to protect the server. Last but not least, we will have a look at the services running and discuss advanced possibilities of securing the server.Read Scalix and Security in full
XDK 11g provides the Simple API for XML (SAX) and the Document Object Model (DOM) API for parsing an XML document. XDK 11g is included with JDeveloper 11g. XDK 11g parsers DOMParser and SAXParser may be configured for schema validation. In the previous article we discussed validating an XML document with an XML schema using XSDValidator. In this article by Deepak Vohra, we will discuss the procedure to validate an XML document with the SAXParser and the DOMParser.Read Schema Validation using SAX and DOM Parser with Oracle JDeveloper - XDK 11g in full
An XML schema document defines the structure, content, and semantics for XML documents. We know the procedure to create an XML schema in JDeveloper and an XML document instance that conforms to the schema. But if you receive XML documents from another party, the validity of the documents has to be ascertained before the documents may be read and processed. This article by Deepak Vohra is about—validating an XML document with an XML schema. An instance document may be processed against a schema to verify whether the XML document conforms to the rules specified in the schema, a process called schema validation.Read Schema Validation with Oracle JDeveloper - XDK 11g in full
In this article by Simon Holmes, author of the book Mongoose for application development, we are going to look at the two building blocks of Mongoose, schemas, and models.

In this article by Francisco J. Blanco-Silva, the author of Learning SciPy for Numerical and Scientific Computing, we will cover the routines in the scipy.spatial module that deal with the construction of triangulations of points in spaces of any dimension, and the corresponding convex hulls. The procedure is simple; given a set of m points in the n-dimensional space (which we represent as an m x n NumPy array), we create the scipy.spatial class Delaunay , containing the triangulation formed by those points.Read SciPy for Computational Geometry in full
