Discovering Python's parallel programming tools

by Jan Palach | June 2014 | Open Source

In this article by Jan Palach, author of Parallel Programming with Python, we will expose some Python libraries to implement parallel solutions.

The Python language, created by Guido Van Rossum, is a multi-paradigm, multi-purpose language. It has been widely accepted worldwide due to its powerful simplicity and easy maintenance. It is also known as the language that has batteries included. There is a wide range of modules to make its use smoother. Within parallel programming, Python has built-in and external modules that simplify implementation. This work is based on Python 3.x.

Shaping a model with Meshmixer and printing it

by Richard Salinas | June 2014 | Cookbooks Open Source

In this article by Richard Salinas, author of the book 3D Printing with RepRap Cookbook, has discussed about shaping a model and then printing it. We're going to take the models that are scanned with 123D Catch and make them better. We'll do this by using Meshmixer, the free program offered by Autodesk. Meshmixer is a 3D modeling program that offers a variety of sculpting tools that manipulate the surface mesh of a 3D model. It also offers a series of tools that are geared to optimize a model for 3D printing. We'll improve the surface of a model by working with its mesh. Later on, in the printing section, we're going to learn how to optimize what we can't see of the model.

Common performance issues

by Osama Oransa | June 2014 | Enterprise Articles

In this article by Osama Oransa, author of Java EE 7 Performance Tuning and Optimization, we will discuss the most common performance issues, classify them, describe the symptoms, and analyze the possible root causes.

Let's now go through the most common performance issues in enterprise applications that we could face during performance troubleshooting. For each issue, we will define the issue, describe it and its symptoms, and give examples. Let's begin with classifying the most common issues and organizing them into different categories.

Getting Started with Mockito

by Marcin Grzejszczak | June 2014 | Open Source

In this article by Marcin Grzejszczak, author of Mockito Cookbook, for those who don't know Mockito at all, he has written a really short introduction about it.

In this article, we will cover the following recipes:

  • Adding Mockito to a project's classpath
  • Getting started with Mockito for JUnit
  • Getting started with Mockito for TestNG
  • Mockito best practices - test behavior, not implementation
  • Adding Mockito hints to exception messages in JUnit (Experimental)
  • Adding additional Mockito warnings to your tests in JUnit (Experimental)
