Getting Started with Lazarus IDE. Get to grips with the basics of programming, debugging, creating, and documenting projects with the Lazarus IDE

Roderick Person

A good integrated development environment can be the key to creating and delivering software on time and budget. Having a programming language and a development environment that runs on multiple platforms greatly eases and lessens the time taken on creating cross-platform applications. An IDE that is compatible with a legacy code base allows developers to leverage existing libraries in future applications.Getting Started with Lazarus is a practical, hands-on guide that provides you with a number of clear step-by-step exercises, which will help you take advantage of the power of the Lazarus IDE and Free Pascal to develop software that can be created for cross-platform use.Getting started with Lazarus discusses developing software with the open source cross platform integrated development environment and the Free Pascal language.We'll learn how to install Lazarus on various platforms such as Linux and Windows, as well as how to create new projects and convert existing Delphi projects to Lazarus projects by learning the differences between Delphi's Pascal syntax and Free Pascal's Object Pascal using a real world example project.We'll learn how to create custom components for use in Lazarus. We'll also learn the basics of documenting a Lazarus project using the Lazarus Documentation Editor.Finally we will learn that the IDE can be rebuilt using a different widget type, specifically GTK 2.Teach yourself the basics of programming with Lazarus and the open source IDE for the Free Pascal language.

Getting started with Audacity 1.3. Create your own podcasts, edit music, and more with this open source audio editor

Bethany Hiitola, Stephen Daulton

Using the Audacity software as the starting off point, we discuss what the software is, what it can do, how you can use it, and where you go to get started installing it. All of this information is grounded in some basic audio editing terminology and background for those that aren't so technology inclined.Then we'll start digging into a sample project! You'll learn about how to set up a project, create a voice track, record an interview with Skype, and basic audio editing techniques. All of this done in an easy to follow, task based approach with lots of examples. Here, we plan to go a step further, we teach how to wrap all of these steps together and create a podcast that can be posted on your own website or blog.There's always more you can do with Audacity! The last portion of the book is dedicated to just that - discussing more advanced editing and mixing techniques, using affects, adding music, adding additional plug-ins to the software. All still incorporating examples and easy to follow tasks you can try on your own audio projects.
