The Raspberry Pi is a credit card-sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games. It also plays high-definition video. This book takes you step-by-step through many fun and educational possibilities. Take advantage of several preloaded programming languages. Use the Raspberry Pi with Arduino. Create Internet-connected projects. Play with multimedia. With Raspberry Pi, you can do all of this and more.

(Jazz Instruction). Whether you're a beginner, an amateur, a professional or a teacher, you will find this book an excellent means of continuing your musical journey. This is a step-by-step guide to help you develop essential skills for improvisation. The concepts presented are first demonstrated over the 12-bar blues progression; in later chapters, the ideas are realized over rhythm changes and in original compisitions based on the chord progressions of jazz standards. Topics include: scales and modes * chords and riffs * transposition * musical quotation * phrasing and articulation.

This book describes how to build and program an Arduino-controlled machine for drawing algorithmic compositions on walls with a marker. The mechanism consists of two stepper motors with spools attached; the motors are attached to either side of the drawing area and a marker is suspended between them attached to fishing line. The motors pull the marker along the wall; with a little trigonometry you can draw straight lines, circles, or Bezier curves. The book builds up a library of drawing elements that can be combined to draw almost anything. The book accompanies a kit available in the Maker Shed, or all the parts can be sourced separately from common parts.

Geared toward Perl users and webmasters, "Perl Graphics Programming focuses on open-source scripting programs that manipulate graphics files for use on the Web. The book demystifies the manipulation of graphics formats for newcomers to the Web with a practical, resource-like approach. With this book you'll learn to: generate dynamic Web graphics with charts, tables, and buttons; automate graphics tasks (thumbnails and borders); create dynamics Web documents (PDF, Postscript); and produce rich Internet experiences with Flash and SVG. You'll begin with a tour of the most common web graphic file formats--PNG, JPEG, GIF, SWF, SVG, Postscript and PDF then you'll explore the most powerful tools and Perl modules available for manipulating these graphics, such as GD, PerlMagick, and GIMP. Included in this part of the book is a thorough description of the Ming module for creating on-the-fly Flash files. Next, a "cookbook" section includes practical, all purpose recipes: GIF animation, generating images within a dynamic application, communicating between SWF front-end and Perl back-end, XSLT transformations, compression, and more.
