Using Debug Perspective – setting breakpoints
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.

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.

Another alternative much discussed by the community of developers is transforming the table into a graphic when it is being displayed on small screen devices. This is not an easy task taking into account the size and amount of data that a table can have.
Let's see an alternative solution combining the previous recipes with another plugin for rendering graphics. The main reason for this combination is we use only one plugin per page, thus optimizing our load.
This article by Fernando Monteiro, the author of the book, Instant HTML5 Responsive Table Design How-to explains what happens when we convert the data and display a nice graphic for our users using a properly formatted table.

In this article by Andriy Lesyuk, author of Instant Google Drive Starter, you will learn how to install and customize Redmine.
For installing Redmine from a package we will use Ubuntu Server 12.04 LTS. Why Ubuntu? Because it's one of the most popular Linux distributions nowadays and Ubuntu is widely used along with Redmine (for example, the TurnKey Linux is also based on Ubuntu).

In this article by Roderick Person, author of Getting Started with Lazarus IDE, we are going to look at creating new components for Lazarus. We will do this by:
-
Creating a message-logging component
-
Adding properties to the components that appear in the Object Inspector window when a component is used in design time
-
Adding events of the components that appear in the Object Inspector window when a component is used in design time
-
Learning the basics of creating a Property Editor window
-
Learning the basics of creating a Component Editor window and looking at the TCheckListBoxComponentEditor component are some examples
So let's begin.

Selecting features from a geographic layer or rows from a standalone attribute table is one of the most common GIS operations. Queries are created to enable these selections, and can be either attribute or spatial queries. Attribute queries use SQL statements to select features or rows through the use of one or more fields or columns in a dataset. An example attribute query would be "Select all land parcels with a property value greater than $500,000". Spatial queries are used to select features based on some type of spatial relationship. An example might be "Select all land parcels that intersect a 100 year floodplain" or perhaps "Select all streets that are completely within Travis County, Texas". It is also possible to combine attribute and spatial queries. An example might be "Select all land parcels that intersect the 100 year floodplain and have a property value greater than $500,000".
In this article by Eric Pimpler, author of Programming ArcGIS 10.1 with Python Cookbook, we will cover the following recipes:
-
Constructing proper attribute query syntax
-
Creating feature layers and table views
-
Selecting features and rows with the Select Layer by Attribute tool
-
Selecting features with the Select by Location tool
-
Combining spatial and attribute queries with the Select by Location tool
SciPy for Computational Geometry
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.
