Gathering all rejects prior to killing a job

by Rick Barton | November 2013 | Open Source

This article by Rick Barton the author of the book Talend Open Studio Cookbook focuses on gathering the rejects. As an alternative to collecting incorrect rows up to the point where a job fails (Die on error), you may wish to capture all rejects from an input before killing a job.

This has the advantage of enabling support personnel to identify all problems with source data in a single pass, rather than having to re-execute a job continually to find and fix a single error / set of errors at a time.

Getting started with Haskell

by Pavel Ryzhov | October 2013 | Open Source

This article by Pavel Ryzhov, the author of Haskell Financial Data Modeling and Predictive Analytics, gives a brief idea about the Haskell platform. The first version of Haskell was standardized in 1990. After a series of intermediate standards, the minimal, stable, and portable version of the language was published as "The Haskell 98 Report" in February 1999. This successful standard was revised in 2003 and published as "Haskell 98 Language and Libraries: The Revised Report". This is the most supported version of the language and it is implemented in many compilers and interpreters of Haskell. The latest specification, Haskell 2010, adds Foreign Function Interface (FFI) for binding to other programming languages, fixes some syntax issues, and introduces several pluggable language extensions. Throughout this article, we will use Haskell 2010.

Working with axes (Should know)

by Brian Peiris | October 2013 | Open Source

In this article by Brian Peiris, the author of the book Instant jQuery Flot Visual Data Analysis, we will understand that the axes are the most configurable parts of the chart. Flot gives you the ability to change the position, type, and colors of the axes. It also gives you full control of the ticks and labels on the axes, letting you adjust the number of ticks and alter the formatting. Axes also determine how the data is displayed; you can change the min and max settings to display only a part of the data on the chart and you can also transform the data in various ways.

The full documentation is available at https://github.com/flot/flot/blob/master/API.md#customizing-the-axes. We will take a look at some examples of the configuration options by creating a chart that has a logarithmic axis and another chart that includes multiple axes.
