  • Chapter 1. Origins of Mac OS X
    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

The main goal is to have to knowledge of how the audience live performance experience can be enhanced through music visualization. With music visualization is possible to give a better understanding about the music feelings constructing an intensive atmosphere in the live music performance, which enhances the connection between the live music and the audience through visuals. These visuals have to be related to the live music, furthermore has to quickly respond to live music changes and introduce novelty into the visuals.

  • Core Animation for Mac OS X and the Iphone
    Prepared exclusively for Ki Wan Han What readers are saying about Core Animation for Mac OS X and the iPhone Animation isn’t “eye candy.” It’s about making GUI experiences less arbitrary and more comprehensible. The developers of Apple’s Core Animation get this, and so does Bill Dudney. His book offers a deep, thoughtful guide to the API and the ideas behind it. Chris Adamson Author of QuickTime for Java: A Developer’s Notebook It’s great to see a book for Mac developers that focuses on one topic and does it well. Its pace is excellent and will allow you to have sim- ple animations running in minutes. As the book goes deeper into its subject, it presents you with just the right amount of information to understand what you are doing so you don’t feel like you are just fol- lowing instructions, yet it never turns into a dry reference manual that overloads you with unnecessary detail. Steve (“Scotty”) Scott The Mac Developer Network (http://www.macdevnet.com) Finally! The comprehensive how-to guide we’ve been waiting for on all our Core Animation needs. Eric Wing Developer As an early adopter of Core Animation technology for the creation of Videator, I have but one regret: if only I had had Bill’s book, I would have finished it in half the time! Andrew Stone CEO, stone.com Prepared exclusively for Ki Wan Han Core Animation is an exciting new library for developers on both the iPhone and the Mac. Bill Dudney’s book makes a great companion for Cocoa programmers looking to add it to their bag of developer tricks.

Retina Displays Today’s Retina Displays have 4x the pixels of previous displays Points Versus Pixels What’s the point • Points have nothing to do with typographer’s “points” • Points are logical coordinates • Pixels are actual device display coordinates • One point is not always equal to one pixel • The “scale factor” is the number of pixels per point • Use points with Quartz 2D, UIKit, AppKit, and Core Animation Retina Displays Set up your scale factor • Set the contentsScale property of layers that you would like to provide high-resolution content • Text, shapes, Quartz 2D drawing, and any layers that you have provided high-resolution images as content • UIKit/AppKit will set the appropriate contentsScale for layers they create layer.contentsScale = [UIScreen mainScreen].scale; Retina Displays Set up your scale factor • The CGContext provided to you via CALayer’s drawInContext will be set up correctly according to its contentsScale property • Any CGContextBitmap you create

  • Building an Image- and Video Processing Application on Apple Ios Platform Using a Parallel Programming Model
    Building an image- and video processing application on Apple iOS platform using a parallel programming model University of Oulu Faculty of Information Technology and Electrical Engineering / M3S Master’s Thesis Ari Ruokamo 25.4.2018 2 Abstract Today powerful parallel computer architectures empower numerous application areas in personal computing and consumer electronics and parallel computation is an established mainstay in personal mobile devices (PMD). During last ten years PMDs have been equipped with increasingly powerful parallel computation architectures (CPU+GPU) enabling rich gaming, photography and multimedia experiences and general purpose parallel computation through application programming interfaces such as OpenGL ES and Apple Metal. Using a narrative literature review this study viewed into current status of parallel computing and parallel programming and specifically its application and practices of digital image processing applied in the domain of Mobile Systems (MS) and Personal Mobile Devices (PMD). While the research on the context is an emerging topic, there still is a limited amount of research available on the topic. As acknowledged in the literature and in the practice, the OpenGL ES programming model for computing tasks can be a challenging environment for many programmers. With OpenGL ES, the paradigm shift from serial- to parallel programming, in addition to changes and challenges in used programming language and the tools supporting the development, can be a barrier for many programmers. In this thesis a Design Science Research (DSR) approach was applied to build an artefact – an image- and video processing application on Apple iOS software platform using OpenGL ES parallel programming model. An Open Source Software (OSS) parallel computing library GPUImage was applied in the implementation of the artefact filtering- and effects functionality.
