What are system frameworks, and why should you care? 2. Brief overview of the frameworks, classes, and APIs that will be demonstrated. 3. Demo 1: PyObjC 4. Demo 2: Objective-C 5. Wrap up and questions. 4 What’s a System Framework? …and why should you care? (OS X) system frameworks provide interfaces you need to write software for the Mac. Many of these are useful for Mac admins creating: • scripts • GUI applications • command-line tools Learning about system frameworks will teach you more about OS X, which will probably make you a better admin. 5 Frameworks, Classes, and APIs oh my! Cocoa CoreFoundation • Foundation • CFPreferences - NSFileManager CoreGraphics - NSTask • Quartz - NSURLSession - NSUserDefaults • AppKit - NSApplication 6 CoreFoundation CoreFoundation is a C framework that knows about Objective-C objects. Some parts of CoreFoundation are written in Objective-C. • Other parts are written in C. CoreFoundation uses the CF class prefix, and it provides CFString, CFDictionary, CFPreferences, and the like. Some Objective-C objects are really CF types behind the scenes. -
What Are the Problems with Embedded Linux?
What Are the Problems with Embedded Linux? Every Operating System Has Benefits and Drawbacks Linux is ubiquitous. It runs most internet servers, is inside Android* smartphones, and is used on millions of embedded systems that, in the past, ran Real-Time Operating Systems (RTOSes). Linux can (and should) be used were possible for embedded projects, but while it gives you extreme choice, it also presents the risk of extreme complexity. What, then, are the trade-offs between embedded Linux and an RTOS? In this article, we cover some key considerations when evaluating Linux for a new development: ■ Design your system architecture first ■ What is Linux? ■ Linux vs. RTOSes ■ Free software is about liberty—not price ■ How much does Embedded Linux cost? ■ Why pay for Embedded Linux? ■ Should you buy Embedded Linux or roll-your-own (RYO)? ■ To fork or not to fork? ■ Software patching ■ Open source licensing ■ Making an informed decision The important thing is not whether Linux or an RTOS is “the best,” but whether either operating system—or both together—makes the most technical and financial sense for your project. We hope this article helps you make an informed decision. Design Your System Architecture First It is important to design your system architecture first—before choosing either Linux or an RTOS—because both choices can limit architectural freedom. You may discover that aspects of your design require neither Linux nor an RTOS, making your design a strong candidate for a heterogeneous approach that includes one or more bare-metal environments (with possibly a Linux and/or RTOS environment as well). -

Programming Java for OS X
Programming Java for OS X hat’s so different about Java on a Mac? Pure Java applica- tions run on any operating system that supports Java. W Popular Java tools run on OS X. From the developer’s point of view, Java is Java, no matter where it runs. Users do not agree. To an OS X user, pure Java applications that ignore the feel and features of OS X are less desirable, meaning the customers will take their money elsewhere. Fewer sales translates into unhappy managers and all the awkwardness that follows. In this book, I show how to build GUIs that feel and behave like OS X users expect them to behave. I explain development tools and libraries found on the Mac. I explore bundling of Java applications for deployment on OS X. I also discuss interfacing Java with other languages commonly used on the Mac. This chapter is about the background and basics of Java develop- ment on OS X. I explain the history of Java development. I show you around Apple’s developer Web site. Finally, I go over the IDEs commonly used for Java development on the Mac. In This Chapter Reviewing Apple Java History Exploring the history of Apple embraced Java technologies long before the first version of Java on Apple computers OS X graced a blue and white Mac tower. Refugees from the old Installing developer tan Macs of the 1990s may vaguely remember using what was tools on OS X called the MRJ when their PC counterparts were busy using JVMs. Looking at the MRJ stands for Mac OS Runtime for Java. -

Introduction to Xgrid: Cluster Computing for Everyone
Introduction to Xgrid: Cluster Computing for Everyone Barbara J. Breen1, John F. Lindner2 1Department of Physics, University of Portland, Portland, Oregon 97203 2Department of Physics, The College of Wooster, Wooster, Ohio 44691 (First posted 4 January 2007; last revised 24 July 2007) Xgrid is the first distributed computing architecture built into a desktop operating system. It allows you to run a single job across multiple computers at once. All you need is at least one Macintosh computer running Mac OS X v10.4 or later. (Mac OS X Server is not required.) We provide explicit instructions and example code to get you started, including examples of how to distribute your computing jobs, even if your initial cluster consists of just two old laptops in your basement. 1. INTRODUCTION Apple’s Xgrid technology enables you to readily convert any ad hoc collection of Macintosh computers into a low-cost supercomputing cluster. Xgrid functionality is integrated into every copy of Mac OS X v10.4. For more information, visit http://www.apple.com/macosx/features/xgrid/. In this article, we show how to unlock this functionality. In Section 2, we guide you through setting up the cluster. In Section 3, we illustrate two simple ways to distribute jobs across the cluster: shell scripts and batch files. We don’t assume you know what shell scripts, batch files, or C/C++ programs are (although you will need to learn). Instead, we supply explicit, practical examples. 2. SETTING UP THE CLUSTER In a typical cluster of three or more computers (or processors), a client computer requests a job from the controller computer, which assigns an agent computer to perform it. -

Reviewer Prof. Dr. Serge Miguet LIRIS Laboratory Université Lumière Lyon 2 Passau – September 17, 2019 Benjamin Planche Bridging the Realism Gap for CAD-Based Visual Recognition Computer Science, September 17, 2019 Reviewers: Prof. Dr. Harald Kosch and Prof. Dr. Serge Miguet University of Passau Chair of Distributed Information Systems Faculty of Computer Science and Mathematics (FIM) Innstr. 33 94032 Passau Abstract Computer vision aims at developing algorithms to extract high-level information from images and videos. In the industry, for instance, such algorithms are applied to guide manufacturing robots, to visually monitor plants, or to assist human operators in recognizing specific components. Recent progress in computer vision has been dominated by deep artificial neural network, i.e., machine learning methods simulating the way that information flows in our biological brains, and the way that our neural networks adapt and learn from experience. For these methods to learn how to accurately perform complex visual tasks, large amounts of annotated images are needed. Collecting and labeling such domain-relevant training datasets is, however, a tedious—sometimes impossible—task. Therefore, it has become common practice to leverage pre-available three-dimensional (3D) models instead, to generate synthetic images for the recognition algorithms to be trained on. -

Cheat Sheets of the C Standard Library
Cheat Sheets of the C standard library Version 1.06 Last updated: 2012-11-28 About This document is a set of quick reference sheets (or ‘cheat sheets’) of the ANSI C standard library. It contains function and macro declarations in every header of the library, as well as notes about their usage. This document covers C++, but does not cover the C99 or C11 standard. A few non-ANSI-standard functions, if they are interesting enough, are also included. Style used in this document Function names, prototypes and their parameters are in monospace. Remarks of functions and parameters are marked italic and enclosed in ‘/*’ and ‘*/’ like C comments. Data types, whether they are built-in types or provided by the C standard library, are also marked in monospace. Types of parameters and return types are in bold. Type modifiers, like ‘const’ and ‘unsigned’, have smaller font sizes in order to save space. Macro constants are marked using proportional typeface, uppercase, and no italics, LIKE_THIS_ONE. One exception is L_tmpnum, which is the constant that uses lowercase letters. Example: int system ( const char * command ); /* system: The value returned depends on the running environment. Usually 0 when executing successfully. If command == NULL, system returns whether the command processor exists (0 if not). */ License Copyright © 2011 Kang-Che “Explorer” Sung (宋岡哲 <explorer09 @ gmail.com>) This work is licensed under the Creative Commons Attribution 3.0 Unported License. http://creativecommons.org/licenses/by/3.0/ .

A Framework for Compiling C++ Programs with Encrypted Operands
1 E3: A Framework for Compiling C++ Programs with Encrypted Operands Eduardo Chielle, Oleg Mazonka, Homer Gamil, Nektarios Georgios Tsoutsos and Michail Maniatakos Abstract In this technical report we describe E3 (Encrypt-Everything-Everywhere), a framework which enables execution of standard C++ code with homomorphically encrypted variables. The framework automatically generates protected types so the programmer can remain oblivious to the underlying encryption scheme. C++ protected classes redefine operators according to the encryption scheme effectively making the introduction of a new API unnecessary. At its current version, E3 supports a variety of homomorphic encryption libraries, batching, mixing different encryption schemes in the same program, as well as the ability to combine modular computation and bit-level computation. I. INTRODUCTION In this document, we describe the E3 (Encrypt-Everything-Everywhere) framework for deploying private computation in C++ programs. Our framework combines the properties of both bit-level arithmetic and modular arithmetic within the same algorithm. The framework provides novel protected types using standard C++ without introducing a new library API. E3 is developed in C++, is open source [2], and works in Windows and Linux OSes. Unique features of E3: 1) Enables secure general-purpose computation using protected types equivalent to standard C++ integral types. The protected types, and consequently the code using them, do not depend on the underlying encryption scheme, which makes the data encryption independent of the program. 2) Allows using different FHE schemes in the same program as well as the same FHE scheme with different keys.
