复变函数与应用 第九版 英文版 作者: ［美］詹姆斯·沃德·布朗 等 (中文版 当当上有卖)

2019出版 Apress. Think Parallel We have aimed to make this book useful for those who are new to parallel programming as well as those who are expert in parallel programming. We have also made this book approachable for those who are comfortable only with C programming, as well as those who are fluent in C++. In order to address this diverse audience without “dumbing down” the book, we have written this Preface to level the playing field. What Is TBB TBB is a solution for writing parallel programs in C++ which has become the most popular, and extensive, support for parallel programming in C++. It is widely used and very popular for a good reason. More than 10 years old, TBB has stood the test of time and has been influential in the inclusion of parallel programming support in the C++ standard. While C++11 made major additions for parallel programming, and C++17 and C++2x take that ever further, most of what TBB offers is much more than what belongs in a language standard. TBB was introduced in 2006, so it contains support for pre-C++11 compilers. We have simplified matters by taking a modern look at TBB and assuming C++11. Common advice today is “if you don’t have a C++11 compiler, get one.” Compared with the 2007 book on TBB, we think C++11, with lambda support in particular, makes TBB both richer and easier to understand and use. TBB is simply the best way to write a parallel program in C++, and we hope to help you be very productive in using TBB.

2019年, Apress出版. Machine learning allows decision makers to gain more insight from their data. Today, the application of machine learning is no longer limited to research and specific industries. In most fields, there is a valuable opportunity to use machine learning to obtain more concise and in-depth information from available data. As a result, most big software companies provide opportunities to their users to access machine learning via easy-to-use software. For example, Microsoft, a pioneer in developing business software, leverages machine learning in developing products such as the Bing search engine, Xbox, Kinect, and others. The use of machine learning in Microsoft is not limited to the production of new software. In many of Microsoft’s software development tools, such as Microsoft SQL Server, Power BI, and .NET, there is an opportunity to use machine learning to create smarter applications and reposts. In this chapter, you will learn the central concepts and approaches to machine learning, review machine learning types, and discover step-by-step the life cycle of machine learning. Also, you will learn about the highly useful machine learning tools that are available in Microsoft products.

2019年 Manning出版, 全英文 ,下面是preface: The field of natural language processing bewitched me as soon as I came to know about it nearly 10 years ago, while studying for my master’s degree. The promise that computers could help us understand the (already, even then) vast amount of textual documents in existence sounded like magic. I still remember how exciting it was to see my first NLP programs extract even vaguely correct and useful information from a few text documents. About the same time, at work, I was asked to do some consulting for a customer on their new open source search architecture. My colleague, who was an expert in the field, was busy on another project, so I was given a copy of Lucene in Action,1 which I studied for a couple of weeks; then I was sent out on the consulting job. A couple of years after I worked on that Lucene/Solr-based project, the new search engine went live (and, as far as I know, it’s still used). I can’t tell you how many times the search engine algorithms needed to be adjusted because of this or that query or this or that fragment of indexed text, but we made it work. I could see users’ queries, and I could see the data that was there to be retrieved, but a minimal difference in spelling or omitting a certain word could cause very relevant information to not show up in the search results. So while I was very proud of my work, I kept wondering how I could have done better to avoid the many manual interventions the product managers asked me to perform in order to provide the best possible user experience. Right after this, I quite by chance found myself involved in machine learning thanks to Andrew Ng’s first machine learning online class (which originated the Coursera MOOC series). I was so fascinated with the concepts behind the neural networks shown in the class that I decided to try to implement a small library for neural networks in Java myself, just for fun (http://svn.apache.org/repos/asf/labs/yay/). I started hunting for other on

2019年 Apress出版 This book is intended for anyone who wants to learn how to program games. It is ideally suited to students who want to learn Python and PyGame on their Raspberry Pi. While not necessary, this book has been oriented toward the Raspberry Pi computer. The Python programming language is ideally suited to beginners and experts alike. The skills you will learn in this book are easily transferable to other computer languages too. If you are unfamiliar with the Raspberry Pi, there are several good eBook guides on getting started including mine called A Slice of Raspberry Pi, available from all good eBook retailers. This book assumes that you are familiar with the Raspberry Pi computer and that you have the Raspberry Pi Foundation’s recommended Raspbian operating system installed. Raspbian is a distribution of the Debian Linux operating system built specifically for the Raspberry Pi. This distribution contains all the Software Development Kits (SDKs) including one for Python that includes PyGame. If you don’t have Raspbian installed, you will have to ensure that you have Python and PyGame installed on your system. Don’t have a Raspberry Pi? Not to worry, you can still learn Python and PyGame. The code in this book will work on other OSs with Python and PyGame installed; Python is a platform-independent language. You can obtain more information and download versions of Python from www.python.org. PyGame can be obtained from www.pygame.org/. Sprites from Ari Feldman’s SpriteLib have been used for the projects contained in this book.

2017 Leanpub出版 Since its inception in 2012, RxJava has slowly gained in popularity for enabling reactive programming on Android. Today in 2017, it is now deemed as the go-to and leading reactive library. Many companies have adopted the reactive way of programming including Google with its release of Android Architecture Components, which has many reactive elements in its design. In Reactive Programming on Android with RxJava, we seek to condense RxJava principles and provide a structured and simplified approach with a lot of code examples. This book seeks to serve as a foundation for experienced Android developers who are new to RxJava so that they can start integrating it into their apps. The book is broken into two parts: The 1st part of the book will go through the basics: In Chapter 1, we will give the backstory of RxJava and discuss what reactive programming is. In Chapter 2, we will examine the core components in RxJava. In Chapter 3, we will dive deeper into operators and highlight a couple of important ones. In Chapter 4, we will cover multithreading and concurrency. The 2nd part of the book will go through advanced concepts: In Chapter 5, we will put together all the lessons from the 1st part of the book and see how they apply to Android. In Chapter 6, we will talk about backpressure to control the flow of data. In Chapter 7, we will go over error handling and how it differs from Java’s exception handling

Manning 2016年出版 Functional programming (FP) holds real solutions to today’s complex software needs, especially the challenges of parallelism. It’s catching on, but there are barriers to its adoption. FRP is a subset of FP that doesn’t require you to learn a new language. This makes FRP an ideal gateway drug to functional programming. FRP solves a specific problem now, yet it gives you grounding in ideas that have wide application. Lambda expressions have now been added to every language. The only thing standing in the way of wide adoption of FRP is gone. FRP is essentially an embedded logic language, so code written in it looks basically the same in any language. It turns out that Java has especially clear FRP syntax, and this was why we chose it as the primary vehicle in this book, but the language really doesn’t matter. There’s a need for FRP, the languages are ready, and functional programming is in vogue. The time is right for FRP to take over a small corner of the world.

Apress 2019出版 Python is one of the most popular languages today. Relatively new fields such as data science, AI, robotics, and data analytics, along with traditional professions such as web development and scientific research, are embracing Python. It’s increasingly important for programmers writing code in a dynamic language like Python to make sure that the code is highquality and error-free. As a Python developer, you want to make sure that the software you are building makes your users happy without going over budget or never releasing. Python is a simple language, yet it’s difficult to write great code because there aren’t many resources that teach how to write better Python code. Currently lacking in the Python world are code consistency, patterns, and an understanding of good Pythonic code among developers. For every Python programmer, great Pythonic code has a different meaning. The reason for this could be that Python is being used in so many areas that it’s difficult to reach consensus among developers about specific patterns. In addition, Python doesn’t have any books about clean code like Java and Ruby do. There have been attempts to write those kinds of books to bring clarity to good Python practices, but those attempts have been few and far between, and quickly frankly, they haven’t been high-quality. The main goal of this book is to provide tips to Python developers of various levels so they can write better Python software and programs. This book gives you various techniques irrespective of the field you use Python in. This book covers all levels of Python, from basic to advanced, and shows you how to make your code more Pythonic. Remember, writing software is not only science but art, and this book will teach you how to become a better Python programmer.

Apress 2019 版 Data is the new oil and unstructured data—especially text, images, and videos—contains a wealth of information. However, due to the inherent complexity in processing and analyzing this data, people often refrain from spending extra time and effort venturing out from structured datasets to analyze these unstructured sources of data, which can be a potential gold mine. Natural language processing (NLP) is all about leveraging tools, techniques, and algorithms to process and understand natural language-based data, which is usually unstructured like text, speech, and so on. In this book, we will be looking at tried and tested strategies—techniques and workflows—that can be leveraged by practitioners and data scientists to extract useful insights from text data.

Published by: John Wiley & Sons, Inc., 111 River Street, Hoboken, NJ 07030-5774, www.wiley.com Copyright © 2019 by John Wiley & Sons, Inc., Hoboken, New Jersey Published simultaneously in Canada Believe it or not, AutoCAD is almost 40 years old, having been born in December 1982, when most people thought that personal computers weren’t capable of industrial-strength tasks like CAD. The acronym stands for Computer-Aided Drafting, Computer-Aided Design, or both, depending on who you talk to. What’s equally scary is that many of today’s hotshot AutoCAD users, and most of the readers of this book, weren’t even born when the program frst hit the street and when the grizzled old-timer writing these words began using it. AutoCAD remains the king of the PC computer CAD hill by a tall margin, making it one of the longest-lived computer programs ever. It’s conceivable that the longterm future of CAD may belong to special-purpose, 3D-based software such as the Autodesk Inventor and Revit programs, or to specialized market-specifc variations built on top of AutoCAD. At any rate, AutoCAD’s DWG fle format is the de facto standard, and so AutoCAD will be where the CAD action is for the foreseeable future. You may have heard that AutoCAD is complex, and therefore is difcult to learn and use. Yes, the user interface includes about 1,300 icons. But it has been my observation that the easier any software is to learn and use, the sooner you bump up against its limitations. A car with no accelerator, one forward gear, no steering, and no brakes would be easy to use until you reached a hill, a curve, or a stop sign or you needed to back out of a parking space. Yes, AutoCAD is complex, but that’s the secret to its success. Some claim that few people use more than 10 percent of AutoCAD’s capabilities. Closer analysis reveals that most people use the same basic 5 percent and everyone else uses a different 5 percent after that. The trick is to fnd your 5 percent, the sweet spot that suits your particular industry. If you follow my advice, I think you will fnd that using AutoCAD is as simple and intuitive as driving a car. It should be perfectly clear that if your career path has put you in a position where you need to know how to use AutoCAD, you’re no dummy!

2019年出版的. Your guide to the functional programming paradigm Functional programming mainly sees use in math computations, including those used in Artificial Intelligence and gaming. This programming paradigm makes algorithms used for math calculations easier to understand and provides a concise method of coding algorithms by people who aren’t developers. Current books on the market have a significant learning curve because they’re written for developers, by developers—until now. Functional Programming for Dummies explores the differences between the pure (as represented by the Haskell language) and impure (as represented by the Python language) approaches to functional programming for readers just like you. The pure approach is best suited to researchers who have no desire to create production code but do need to test algorithms fully and demonstrate their usefulness to peers. The impure approach is best suited to production environments because it’s possible to mix coding paradigms in a single application to produce a result more quickly. Functional Programming For Dummies uses this two-pronged approach to give you an all-in-one approach to a coding methodology that can otherwise be hard to grasp. Learn pure and impure when it comes to coding Dive into the processes that most functional programmers use to derive, analyze and prove the worth of algorithms Benefit from examples that are provided in both Python and Haskell Glean the expertise of an expert author who has written some of the market-leading programming books to date If you’re ready to massage data to understand how things work in new ways, you’ve come to the right place!
