Planning is a key element of any IT implementation, but planning can only be accomplished with an understanding of the technical underpinnings of the proposed solution. In this article, authors Mitesh Desai and Dan Renfroe delve more deeply into the technical architecture of BES in order to provide you with an understanding of what’s under the hood. This article also covers the system requirements and pre-requisites for a BES implementation, including operating system, hardware, network, and database requirements.Read BlackBerry: BES Architecture and Implementation Planning in full
Python LDAP Applications: Part 1 - Installing and Configuring the Python-LDAP Library and Binding to an LDAP Directory
This article mini-series by Matt Butcher will look at the Python application programmers interface (API) for the LDAP libraries, and using this API, we will connect to our OpenLDAP server and manipulate the directory information tree. More specifically, we will cover the following in this article series:
- Installing and configuring the Python-LDAP library.
- Binding to an LDAP directory.
- Comparing attributes between the client and server.
- Performing searches on the directory.
- Modifying the directory information tree with add, delete, and modify operations.
- Modifying directory passwords.
- Working with LDAP schemas.
This first part will deal with installation and configuration of the Python-LDAP library. We will then see how the binding operation is performed.Read Python LDAP Applications: Part 1 - Installing and Configuring the Python-LDAP Library and Binding to an LDAP Directory in full
LINQ to Objects means that we can use LINQ to query objects in a collection. We can access the in-memory data structures using LINQ. We can query any type of object that implements the IEnumerable interface or IEnumerable
In this article, author N. Satheesh Kumar shows us how to query different objects using LINQ operators and avoid having to use the looping method to filter the values in a collection.Read LINQ to Objects in full
Objects confused me when I started to use CodeIgniter. I came to CodeIgniter via PHP 4, which is a procedural language, not really an Object-Oriented (OO) language. I duly looked up objects and methods, properties and inheritance, and encapsulation, but my early attempts to write CI code were plagued by the error message "Call to a member function on a non-object". I saw it so often that I was thinking of having it printed on a t-shirt: it has a mysteriously libertarian, anarchist tone, and I could see myself wearing it at a modern art exhibition.
This is the geek article. It describes the way CodeIgniter actually works, 'under the hood'. If you are new to CI, you may want to skip it. However, sooner or later, you may want to understand why things happen in certain ways—as opposed to just knowing that they do.Read CodeIgniter and Objects in full
Integration is a necessary evil using which we can interconnect systems, applications and services to facilitate seamless information flow within and across Organization boundaries. We have been using technologies like JSP, EJB, JMS, etc. in the Java world for building Enterprise Applications (EA). But if we have to interconnect such applications, we will need Enterprise Application Integration (EAI). Many a times we also use EA technologies and tools to do EAI. This will give a short term solution to our integration problems, which may not scale up when we want to perform integration at Enterprise (Customers, Vendors, Partners, ...) level. Java Business Integration (JBI) is the new specification trying to fill this gap of EAI in the Java world. So next time when you want to integrate, don't write a single line of Java code, instead plug and assemble JBI based integration libraries to control your message flow! Does it looks promising? Believe it or read the article below to get yourself convinced.
In this article by Binildas Christudas, we will look into Integration in general and to JBI and ESB in particular. We will then explain few functionalities usually done by integration components like protocol conversions, content transformations, etc., with some code snippets too.Read Aggregate Services in ServiceMix JBI ESB in full
