Binding MS Chart Control to LINQ Data Source Control

by Jayaram Krishnaswamy | August 2009 | Microsoft

In this article by Dr. Jay Krishnaswamy, a Microsoft Chart Control will be bound to a Linq Data Source using LinqDataSource control and a pie chart displays the data.

We will be going through the following steps:

  • Create a Framework 3.5 web site project
  • Add a LinqDataControl and provide the data context
  • Add a MS Chart Control and bind it to the LinqDataSource

Big Data Analysis

by Brian Femiano Jon Lentz Jonathan R. Owens | May 2013 | Cookbooks Open Source

This article created by Jonathan R. Owens, Jon Lentz, and Brian Femiano, authors of Hadoop Real-World Solutions Cookbook, contains recipes designed to show how you can put Hadoop to use to answer different questions about your data. Several of the Hive examples will demonstrate how to properly implement and use a custom function (UDF) for reuse in different analytics. There are two Pig recipes that show different analytics with the Audioscrobbler dataset and one MapReduce Java API recipe that shows Combiners.

In this article, we will cover:

  • Counting distinct IPs in weblog data using MapReduce and Combiners

  • Using Hive date UDFs to transform and sort event dates from geographic event data

  • Using Hive to build a per-month report of fatalities over geographic event data

  • Implementing a custom UDF in Hive to help validate source reliability over geographic event data

  • Marking the longest period of non-violence using Hive MAP/REDUCE operators and Python

  • Calculating the cosine similarity of Artists in the Audioscrobbler dataset using Pig

  • Trim outliers from the Audioscrobbler dataset using Pig and datafu

Learning to apply Apache Hive, Pig, and MapReduce to solve the specific problems you are faced with can be difficult. The recipes in this article present a few big data problems and provide solutions that show how to tackle them. You will notice that the questions we ask of the data are not incredibly complicated, but you will require a different approach when dealing with a large volume of data. Even though the sample datasets in the recipes are small, you will find that the code is still very applicable to bigger problem spaces distributed over large Hadoop clusters.

The analytic questions in this article are designed to highlight many of the more powerful features of the various tools. You will find many of these features and operators useful as you begin solving your own problems.

BatteryMonitor Application

by Steven F Daniel | November 2012 | Enterprise Articles

The BatteryMonitor application allows you to monitor the state and battery levels of your iOS device using the APIs that come with the iOS SDK. Each iOS device represents a unique set of properties that include the device's current physical orientation, its model name, and its battery state. It also provides access to the onboard hardware.

This article by Steven F Daniel, author of iPad Enterprise Application Development BluePrints, we will be taking a closer look at how we can use the Core Graphics framework to create and draw a gauge that will be use to present and visualize the total amount of battery life remaining on the iOS device, and then start to design the user interface for our app.

Basic Skills, Traits, and Competencies of a Manager

by Rahul Goyal | May 2012 | Enterprise Articles

In India, being a Manager is highly valued. A majority of people see themselves taking a managerial position some day. However, can anyone become a manager? A really good manager? Are managers born or made? Do all managers, at least all good managers, share something in common?

When we look around and see the journeys being taken by different managers, their working styles and behaviors, we can hypothesize that:

  • Managers are born and made. Some folks have a natural flair to be a manager and some acquire essential skills to be a manager in a given situation.
  • Not everyone may enjoy being a manager. While you may be 'promoted' to become a manager, you may find that you don't really enjoy the time spent talking to people, driving them to results, and compiling status reports for your management.
  • It appears that good managers do have many things in common, even though they may have their own style of execution.

In this article by Rahul Goyal author of Management in India: Grow from an Accidental to a Successful Manager in the IT & Knowledge Industry , we will explore the skills, traits, talents, and competencies that are usually required and expected for playing a manager role, and also burst some myths surrounding managers.

Basic Dijit Knowledge in Dojo

by Peter Svensson | December 2008 | AJAX Open Source

In this article by Peter Svensson, we will have a look at Dijit or Dojo Widget which is an instance of a Dojo class that lives in the page and usually has a DOM node associated with it. Examples are FloatingPane, Tree, NumberSpinner, and ValidationtextBox.

The basic premise of a Dijit is that you should be able to create any number of widgets of the same type on the same page, regardless of where on the page you choose to put them. Certain Dijits have special requirements, naturally, such as the Layout Containers, which assume that they are surrounding ContentPane Dijits.

In general, Dijits are very versatile and much time has been spent to assure portability and modularization of the Dijit system. Best of all, this is accessible to you as a developer as well.

Basic Concepts and Architecture of Cassandra

by Vijay Parthasarathy | November 2013 | Open Source Web Development

This article has been created by Vijay Parthasarathy, the author of Learning Cassandra for Administrators. The Apache Cassandra database is a linearly scalable and highly available distributed data store which doesn't compromise on performance and runs on commodity hardware. Cassandra's support for replicating across multiple datacenters / multiple discrete environments is the best in the industry. Cassandra provides high throughput with low latency without any single point of failure on commodity hardware.

Cassandra was inspired by the two papers published by Google (BigTable) in 2006 and Amazon (Dynamo) in 2007, after which Cassandra added more features. Cassandra is different from most of the NoSQL solutions in a lot of ways: the core assumption of most of the distributed NoSQL solutions is that Mean Time Between Failures (MTBF) of the whole system becomes negligible when the failures of individual nodes are independent, thus resulting in a highly reliable system.
