Checking OpenStreetMap Data for Problems

by Jonathan Bennett | September 2010 | Open Source

OpenStreetMap is a diverse project with hundreds of thousands of people contributing data and making use of it in different ways. As a result, many of the resources that mappers have created and use are scattered around the Internet, but the project data and much of the documentation is hosted at openstreetmap.org, on servers operated by the OpenStreetMap Foundation.

In this article by Jonathan Bennett, author of the book OpenStreetMap, we'll look at some of the following tools you can use to check OpenStreetMap data in a particular area, and what problems they can and can't tell you about:

  • The data inspection tools on openstreetmap.org
  • The NoName map
  • ITOWorld OSM Mapper
  • Geofabrik's OSM Inspector

Some of these tools identify specific problems, while others allow you to see when changes to the data were made and by whom. In either case, all these tools can do is offer guidance, not black-and-white answers, and you always need to use judgment when checking data.

Installing and Configuring Joomla! 1.5

by Santonu Kumar Dhar | September 2010 | Joomla! Open Source

Joomla! has earned a reputation of being one of the most powerful CMS programs around, as its core team emerged from another popular open source Content Management System (CMS) program called Mambo. Joomla! was downloaded more than 2.5 million times within the first year of its release. It has over 200,000 community users and contributors. Although Joomla! is so popular, building jobsites with Joomla! is a new concept.

To build a jobsite, you need to use a jobs and recruitment extension (such as Jobs!, Jobline!, or JS Jobs) in your Joomla! website. We will use the Jobs! extension because it provides all of the functionalities that a professional jobsite should have. It provides graphical user interface for administrator, employer, and jobseeker. Before we start how to develop a jobsite with Joomla!, we need to install and configure Joomla! 1.5 and Jobs! extension along with all of its modules.

This article by Santonu Kumar Dhar, author of the book Building job sites with Joomla!, explains:

  • Prerequisites for installation of Joomla! 1.5 and Jobs!
  • Setting up a local server environment
  • Uploading installation packages and files to server
  • Creating database and user for the database
  • Installing and configuring Joomla! 1.5

Inserting Multiple Entries with MySQL for Python

by Albert Lukaszewski, PhD | September 2010 | MySQL Open Source

When we deal with large amounts of data that are all going into the same database, running single instances of individual INSERT commands can take a ridiculous amount of time and waste a considerable amount of I/O. What we need is a way to insert multiple items in one go.

In this article, Albert Lukaszewski, PhD, author of MySQL for Python, we will look at the following:

  • How iteration can help us execute several individual INSERT statements rapidly
  • Using executemany() to submit several INSERT statements in one go
  • When not to use executemany()
  • Throttling how much data is inserted at a time

Introduction to Game Development Using Unity 3D

by Ryan Henson Creighton | September 2010 | Web Graphics & Video

This article by Ryan Henson Creighton, author of Unity 3D Game Development by Example, introduces you to Unity 3D—an amazing game engine that enables you to create games and deploy them to a number of different devices, including (at the time of writing) the Web, PCs, iOS platforms, and WiiWare, with modules for Android and Xbox Live Arcade deployment in the works. You'll play a number of browser-based Unity 3D games to get a sense of what the engine can handle, from a massively-multiplayer online game all the way down to a simple kart racer. You'll download and install your own copy of Unity 3D, and mess around with the beautiful Island Demo that ships with the product.
