Building a successful intranet is not an easy job. When we are asked to build an intranet there is always an implicit requirement that doesn't show in any requirement list. This requirement is easy in concept, but hard to achieve: the intranet must be a success in terms of usability and use. The last thing we will want is that it ends up being one of those web services that people barely use. In this article, by Víctor Fernández de Alba, author of Plone 3 Intranets, we will cover the key factors for the success of an intranet and the effective use of the content types.
We will cover the following topics:
- Navigation and taxonomy
- Table of contents
- Next/previous folder
- Presentation mode
- Best practices for third-party content types
We can make building an intranet an easy task if we want to do so. As we already know, a content type is not only an information container; it also defines the way the information is shown to the consumer via the content view. We will learn to use the right content type and its right view for the right job. Another crucial factor is to extend wisely our default content type set via third-party add-on products. We will learn how to choose and use them correctly.Read Using Content Type Effectively with Plone Intranet in full
In the previous article we looked at ways to structure and access data objects to make your application faster and more scalable.

The article, Using Debug Perspective, will guide you through the ways of setting up breakpoints and navigate through the code using various breakpoint manipulation options. This article by Anatoly Spektor, author of Instant Eclipse Application Testing How-to, will guide you to learn what breakpoints are and how to use them. After reading this article, you will be able to effectively debug Java applications of any scope. Fortunately, any prior knowledge of Eclipse is not required; thus it is suitable for developers with any level of experience in Eclipse application development and testing.Read Using Debug Perspective – setting breakpoints in full

In this article written by Fabio Mazanatti Nunes and William Markito Oliveira authors of the book, Getting Started with Oracle WebLogic Server 12c: Developer's Guide, we are going to briefly introduce two concepts of Java EE development: interceptors and events. We will also see how to integrate these concepts with WebLogic services. It's a common misunderstanding that these technologies are complex and difficult to use, but after working with examples of this article, it will become clear that they are powerful yet easy to use. Along the way, we will cover WebLogic Server's logging services, which shows us how to configure the framework, how to write messages to it, and how to read them using the administration console.Read Using Events, Interceptors, and Logging Services in full
Natural Language Processing is used everywhere—in search engines, spell checkers, mobile phones, computer games, and even in your washing machine. Python's Natural Language Toolkit (NLTK) suite of libraries has rapidly emerged as one of the most efficient tools for Natural Language Processing.
In this article by Jacob Perkins, author of the book Python Text Processing with NLTK 2.0 Cookbook, we will cover:
- Distributed tagging with execnet
- Distributed chunking with execnet
- Parallel list processing with execnet
This article series by Tom Gross, author of Plone 3 Multimedia, explains how to add audio content to Plone and enhance its features with Plone4Artists products. It also shows how to include audio data in HTML with plugins and Flash.
There are at least four use cases when we think of integrating audio in a web application:
- We want to provide an audio database with static files for download.
- We have audio that we want to have streamed to the Internet (for example, as a podcast).
- We want a audio file/live show streamed to the Internet as an Internet radio service.
- We want some sound to be played when the site is loaded or shown.
In this article we will discuss three of the four cases. The streaming support is limited to use case 2. We can stream to one client like a podcast does, but not to many clients at once like an Internet Radio does. We need special software such as Icecast or SHOUTcast for this purpose. Further, we will investigate how we solve use cases 1, 2, and 3 with the Plone CMS and extensions. Technically, these are the topics covered in this article:
- Manipulation of audio content stored as File content in Plone
- The different formats used for the binary storage of audio data
- Storing and accessing MP3 audio metadata with the ID3 tag format
- Managing metadata, formats, and playlists with p4a.ploneaudio in Plone
- Including a custom embedded audio player in Plone
- Using the Flowplayer product to include an audio player standalone in rich text and as a portlet
- Previewing the audio element of HTML5
- Extracting metadata from a FLAC file using mutagen
In this article by Luca Milanesio, author of the book Learning Gerrit Code review, we will learn about Gerrit Code revew. GitHub is the world's largest platform for the free hosting of Git Projects, with over 4.5 million registered developers. We will now provide a step-by-step example of how to connect Gerrit to an external GitHub server so as to share the same set of repositories. Additionally, we will provide guidance on how to use the Gerrit Code Review workflow and GitHub concurrently.
By the end of this article we will have our Gerrit installation fully integrated and ready to be used for both open source public projects and private projects on GitHub.Read Using Gerrit with GitHub in full
In this article by Dinangkur Kundu and S. M. Ibrahim Lavlu, we will see how to add network-attached devices in the Cacti system and produce graphs to monitor LAN-sized installations to complex networks with hundreds of devices. It is fairly easy to manage devices through the Cacti web front-end. It provides a fast poller, advance graph templating, and multiple data acquisition methods out of the box, wrapped in an easy to use interface that makes sense to the network administrator.Read Using Graphs to Manage Networks and Devices with Cacti 0.8 in full
A good software developer always keeps the DRY principle in mind. Whenever code is duplicated, maintainability problems are introduced and the code base becomes difficult to understand. Java developers often rely on the template method pattern to reuse code. Groovy's closure programming concept is an alternative way to solve similar problems. Closures provide a concise way to pass around code without the ceremony involved with design patterns. This article by Nirav Assar will demonstrate how closures are used to embrace the DRY principle.Read Using Groovy Closures Instead of Template Method in full
So far, we have only used Hive through its interactive console. In this article by Darren Lee, author of Instant Apache Hive Essentials How-to [Instant], we will learn how Hive supports uses cases, such as periodic ETL jobs, by rerunning the top athletes query in batch mode from the command line. This support allows us to use external tools to start Hive jobs and capture their output.Read Using Hive non-interactively (Simple) in full

The article, using indexes to manipulate objects in pandas, covers the important aspects of pandas. This article by Trent Hauck, author of the book Instant Data Intensive Apps with pandas How-to , gives an idea of about the importance of indexes in pandas.
Indexes are not advanced because they're difficult, but if we want to be an expert with pandas it is important that we use them well. We will discuss hierarchical indexes in the following There's more... section.Read Using indexes to manipulate pandas objects in full
A Windows Azure hosted service may comprise multiple instances of multiple roles. These instances all run in a remote Windows Azure data center—typically 24*7. The ability to monitor these instances non-intrusively is essential both in detecting failure and in capacity planning.
However, there are times, especially early in the development process, when non-intrusive diagnostics monitoring is not sufficient. In this article by Neil Mackenzie, author of Microsoft Windows Azure Development Cookbook, we will see the benefits of intrusive monitoring of a Windows Azure role instance using IntelliTrace.Read Using IntelliTrace to Diagnose Problems with a Hosted Service in full
