Interprocess Communication with Macos
Build highly modular software in macOS that interacts deeply and intuitively with other programs. This book explores all techniques available for Inter-process communications (IPC) from high level macOS layers to deep kernel options while applying theoretical concepts into practical implementations on real world scenarios.You'll see how IPC techniques are used for exchanging data and messages among multiple threads in one or more processes, which may be running on one or more computers connected by a network or running locally. IPC methods can be divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). A poorly conceived IPC can even expose an entire network to over-the-network attacks. Despite the risks, processes and applications absolutely need to communicate with each other across your system and the network. You'll see how these communications facilitate information sharing, computational speedup, modularity, convenience, and privilege separation. In macOS, a program has a number of ways to communicate with other programs. These mechanisms for IPC often exist in different layers of the system. You'll examine how each has its own specific purposes, limitations, and intended scenarios. Some are more suitable than others for code written at a certain level of the system. For example, a kernel extension would not make use of Apple events. Additionally, the book reveals that different users have different rights when it comes to accessing files, changing system wide settings, and so on, depending on whether they are admin users or ordinary users. Running code with root or administrative privileges can intensify the dangers posed by security vulnerabilities. You'll learn that to elevate privileges safely, it is mandatory for the application to perform the task through a secure Helper process.What You'll LearnExpand the capabilities of your programs by sharing data within multiple applicationsUnderstand and dig deep into the world of Helper tools to create apps that need user privilege elevationEnhance the modularity of a system by allowing your applications to interact and share data with a websiteWho This Book Is ForSoftware engineers and architects designing and developing secure applications for macOS and iOS who have hands-on knowledge of Swift with XCode.
Mastering Swift Package Manager
Maintaining an iOS project often results in thousands of code files scattered around your folders. Did you ever wanted to reuse those files with other projects but found yourself making copies of Swift files? You are not alone! Many iOS developers struggle with this issue as well--unorganized projects, duplicated files, difficulty in testing, and long complication times. This book will show how Swift Package Manager can help you handle these problems by restructuring your project to make it efficient and straightforward. Swift Package Manager isn't magic, but you'll likely need a little guidance in using this nifty tool. You'll see how to reorganize projects smartly and efficiently, create your first Swift package, and learn what libraries are in this context. Then share your package with the rest of your projects. Next test your library's quality. And then take your library to the next level of power by including files that go beyond just code. By going over the methodology of big project organization, you will have the ability to extend your project into the future as Apple sees it. Make no mistake--the path for a modular and flexible project is not easy. With the help of Swift Package Manager, it becomes possible and worth it. What You'll LearnCreate a Swift package both from the command line and from Xcode Manage Swift packages in public and private Git repositories Build test suites to test integrations between packagesWho This Book Is For Senior iOS developers and team leaders who already have professional experience with Swift.

React to Python
Learn to create responsive front-end web applications in Python using the React and Material-UI JavaScript libraries without having to program in JavaScript! How is this possible? By using the Transcrypt transpiler that turns your Python code into JavaScript.Let's face it, JavaScript is the way of the web, and Python doesn't run in a web browser. BUT, just like the popular TypeScript language that gets compiled into JavaScript to run in a web browser, Transcrypt does the same thing for Python. Because of the way Transcrypt maps Python data types and language constructs to JavaScript, your Python code is able to directly utilize the full ecosystem of JavaScript libraries that exist, taking advantage of existing web application technologies rather than trying to replace them.Using a Python-centric viewpoint, this book outlines the developer tools and software libraries needed to develop front-end web applications with Python, specifically focusing on the popular React library and open-source Material-UI library that includes a collection of React components based on Google's Material Design user interface specification. In addition to chapters covering how to implement specific application features, in a learn-by-doing fashion, the last section of the book walks you through building a fully functional example application from start to finish, giving you an idea of how everything fits together.While this book isn't necessarily meant for beginning programmers, if you are already familiar with Python and want to create front-end web applications but don't want to have to delve into the complexities of a full JavaScript ecosystem, don't want to have to keep switching back and forth between languages for the same full-stack application, or if you just don't care to program in JavaScript in general, the approach taken in this book gives you another option using Python.

Foundations of Object-Oriented Languages
A presentation of the formal underpinnings of object-oriented programming languages.In recent years, object-oriented programming has emerged as the dominant computer programming style, and object-oriented languages such as C++ and Java enjoy wide use in academia and industry. This text explores the formal underpinnings of object-oriented languages to help the reader understand the fundamental concepts of these languages and the design decisions behind them. The text begins by analyzing existing object-oriented languages, paying special attention to their type systems and impediments to expressiveness. It then examines two key features: subtypes and subclasses. After a brief introduction to the lambda calculus, it presents a prototypical object-oriented language, SOOL, with a simple type system similar to those of class-based object-oriented languages in common use. The text offers proof that the type system is sound by showing that the semantics preserves typing information. It concludes with a discussion of desirable features, such as parametric polymorphism and a MyType construct, that are not yet included in most statically typed object-oriented languages.
Parallel Programming Using C++
Foreword by Bjarne Stroustrup Software is generally acknowledged to be the single greatest obstacle preventing mainstream adoption of massively-parallel computing. While sequential applications are routinely ported to platforms ranging from PCs to mainframes, most parallel programs only ever run on one type of machine. One reason for this is that most parallel programming systems have failed to insulate their users from the architectures of the machines on which they have run. Those that have been platform-independent have usually also had poor performance. Many researchers now believe that object-oriented languages may offer a solution. By hiding the architecture-specific constructs required for high performance inside platform-independent abstractions, parallel object-oriented programming systems may be able to combine the speed of massively-parallel computing with the comfort of sequential programming. Parallel Programming Using C++ describes fifteen parallel programming systems based on C++, the most popular object-oriented language of today. These systems cover the whole spectrum of parallel programming paradigms, from data parallelism through dataflow and distributed shared memory to message-passing control parallelism. For the parallel programming community, a common parallel application is discussed in each chapter, as part of the description of the system itself. By comparing the implementations of the polygon overlay problem in each system, the reader can get a better sense of their expressiveness and functionality for a common problem. For the systems community, the chapters contain a discussion of the implementation of the various compilers and runtime systems. In addition to discussing the performance of polygon overlay, several of the contributors also discuss the performance of other, more substantial, applications. For the research community, the contributors discuss the motivations for and philosophy of their systems. As well, many of the chapters include critiques that complete the research arc by pointing out possible future research directions. Finally, for the object-oriented community, there are many examples of how encapsulation, inheritance, and polymorphism can be used to control the complexity of developing, debugging, and tuning parallel software.

Real Programming
Based on the Norwegian version, this is a book about real programming for real programmers. Or for those who have an interest in programming but have grown tired of the available selection in bookstores. Yes, they still exist. Bookstores, I mean. And books. Real programming has existed since the dawn of time, a.k.a. the mid 70s with the launch of the 6502 and Z80 CPUs. Back then, code was written by hackers in real languages like assembler and C. With the launch of the 68000 based Commodore Amiga in the 80s, another hacker revolution was born. Unfortunately, in the middle of the 90s the internet grew popular and ruined it. And then the smartphones ruined it all again in 2007. Someone had the dubious idea that programming should be easy and for everybody, and new programming languages and methods were developed with that in mind. Corneliusen and Julin claim the result was a disaster, since everything, at best, turned average: The code, the speed, the programmers, the managers, and the salary. And people still wonder why their smartphone batteries drain so quickly. Or why companies flush money down the toilet by writing software in programming languages similar to Duplo, and then run them in the cloud where they pay per CPU second used. Programming is like playing a guitar: It's possible to do it for years without becoming better than well below average. To be really good, everything has to be questioned. And that's what this book is about: Instead of forcing the reader to memorize complex methods and formulas, assorted problems are broken down to their essence and reassembled in new ways. Not because it's necessary, but because it's important to figure out how things work. The authors claim that by doing this, even the hardest problems become simple. Sometimes the presented solutions are improvements, and sometimes they're just entertaining. It should be noted that the book contains a lot of real code in C, Assembler, and GLSL for the architectures ARM and Neon, Intel SSE2 and AVX2, and the slightly obscure mega-multicore CPU formerly known as the Tilera TILE-Gx.

Building Custom Tasks for SQL Server Integration Services
Build custom SQL Server Integration Services (SSIS) tasks using Visual Studio Community Edition and C#. Bring all the power of Microsoft .NET to bear on your data integration and ETL processes, and for no added cost over what you've already spent on licensing SQL Server. New in this edition is a demonstration deploying a custom SSIS task to the Azure Data Factory (ADF) Azure-SSIS Integration Runtime (IR). All examples in this new edition are implemented in C#. Custom task developers are shown how to implement custom tasks using the widely accepted and default language for .NET development. Why are custom components necessary? Because even though the SSIS catalog of built-in tasks and components is a marvel of engineering, gaps remain in the available functionality. One such gap is a constraint of the built-in SSIS Execute Package Task, which does not allow SSIS developers to select SSIS packages from other projects in the SSIS Catalog.

Xanpan
Xanpan is...a cross between XP and Kanban... is an example of a roll-your-own method... is distilled from Allan Kelly's own experiences running development teams and then helping multiple teams adopt Agile working methods and practices. Xanpan draws ideas from Kanban and Lean, XP and Scrum, product management and business analysis, and many other places. Allan tells the Xanpan story through a series of boards which tell the story of different teams. In between he fills in the principles, practices and thinking which together constitutes Xanpan. Allan's key points include: handling planned and unplanned work in fixed length iterationsthe importance of keeping quality high with technical practicesplanning beyond the iterationand why deadlines are more important than estimates. Online Reviews "Thoroughly enjoyed XanPan. Allan challenges unfounded assumptions and really unearths a simplicity to writing about Agile and effective ways of working."Amazon Review "This book, very concise, is a goldmine. In a very accurate way, it will guide you through the implementation of the best from Kanban and Scrum."Amazon Review - Mr. Umiastowski Nicolas "This book is an important contribution to the agile literature. It tackles the challenges that most teams face, head-on, by proposing alternatives that some might consider heretical. This sort of discussion is invaluable in the face of corporate certification of activities that promote blind faith and dogma rather than observation and critical thought."Amazon Review - Seb Rose "Having bounced back and forth between Kanban and Scrum (including a brief foray into Scrumban) it's great to finally come across an agile methodology that's designed to work in the real world, with all the joys that brings. Allen introduces Xanpan in a manner than is accessible to more than just techies and provides a useful set of tools which you can use 'as is', or customise to fit your team and process."Amazon Review - Dom Davis "An excellent book giving real examples and experiences of the adoption of lean and Kanban models within software development teams."Amazon Review - Belinda Waldock
How Open Source Ate Software
Learn how free software became open source and how you can sell open source software. This book provides a historical context of how open source has thoroughly transformed how we write software, how we cooperate, how we communicate, how we organize, and, ultimately, how we think about business values. This fully updated second edition includes an entire chapter on legal considerations such as trademarks and the latest happenings in open source licensing. It also expands on open hardware trends such as RISC-V, open governance, and the difference between community projects and commercial products, especially as seen through the lens of security. You'll look at project and community examples including Linux, BSD, Apache, and Kubernetes, understand the open source development model, and how open source has influenced approaches more broadly, even within proprietary software, such as open betas. You'll also examine the flipside, the "Second Machine Age," and thechallenges of open source-based business models. Today, open source serves as shorthand for much broader trends and behaviors. It's not just about a free (in all senses of the word) alternative to commercial software. It increasingly is the new commercial software. How Open Source Ate Software, second edition reveals how open source has much in common, and is often closely allied, with many other trends in business and society. You'll see how it enables projects that go beyond any individual company. That makes open source not just a story about software, but a story about almost everything. What You'll Learn The opportunities that open source creates and the challenges that come with themThe ways in which companies can create business models to successfully sell "free" softwareHow the open source development model works from creating communities to selling commercial productsThe important issues associated with open source project and product governance and licensingHow open source principles can apply more broadly to DevOps and other organizational practices Who This Book Is For Anyone who is contemplating building a community and a business around open source software.
14 Habits of Highly Productive Developers
Why This Book?You can learn the most popular frameworks, use the best programming languages, and work at the biggest tech companies, but if you cultivate bad habits, it will be hard for you to become a top developer.This book doesn't offer a straight path or pre-defined formula of success. This book is a result of a quest. A quest to uncover what habits can be cultivated to become a better software engineer."I wish I had access to this book while I was starting in the software industry. The information presented is not only logical, not only personal, but very well backed up by many expert opinions throughout the book. A must-read, for both beginners and experts alike." - Zachary Sohovich, Software Engineer at NikeWhat Will You Read?How to keep up with all the new technologiesWhat should you focus? Being a specialist or generalist?How to stay productive and not feel overwhelmedThe importance of estimating tasks correctlyHow to approach new side project ideasAnd much moreWho Should Read This Book?It doesn't matter if you're a Junior or Senior developer. It doesn't matter how experienced you are. This book can help you cultivate new habits or rethink existing behaviors.What's Inside?This is not a traditional book. You won't find the same format or structure that a regular book has. In fact, this book was designed to be as simple and objective as possible. You can follow the order of chapters, or you can read them individually. Everything is standalone and doesn't depend on previous knowledge.At the end of each chapter, you'll find a section marked as "Questions & Answers", where I interview senior developers and tech leads from various companies to understand how they got there. I went after tech giants such as Google, Amazon, Microsoft, and Adobe. Powerful startups such as GitHub, Spotify, Elastic, Segment, GoDaddy, and Shopify.

Aesthetic Programming
The book explores the technical as well as cultural imaginaries of programming from its insides. It follows the principle that the growing importance of software requires a new kind of cultural thinking - and curriculum - that can account for, and with which to better understand the politics and aesthetics of algorithmic procedures, data processing and abstraction. It takes a particular interest in power relations that are relatively under-acknowledged in technical subjects, concerning class and capitalism, gender and sexuality, as well as race and the legacies of colonialism. This is not only related to the politics of representation but also nonrepresentation: how power differentials are implicit in code in terms of binary logic, hierarchies, naming of the attributes, and how particular worldviews are reinforced and perpetuated through computation. It introduces and demonstrates the reflexive practice of aesthetic programming, engaging with learning to program as a way to understand and question existing technological objects and paradigms, and to explore the potential for reprogramming wider eco-socio-technical systems. The book itself follows this approach, and is offered as a computational object open to modification and reversioning.
