Description A new generation of serverless tools, including Claudia.js, make it radically easier to set up serverless web applications so users can focus on what their app does instead of meddling with infrastructure configuration and deployment. Serverless Apps with Node and Claudia.js walks readers through building serverless apps on AWS using JavaScript. They'll learn to simplify the design and development process so they can focus on getting their application deployed as fast as possible without sacrificing quality. Key features * Create a serverless API using AWS Lambda and Claudia.js * Build a voice assistant with Amazon Alexa * Develop microservices with Node.js, AWS Lambda, S3, and more * Create a chatbot for multiple platforms Audience Written for beginner and intermediate web developers comfortable with JavaScript and Node.js. Some prior experience with AWS is required. About the technology Serverless computing services like AWS Lambda and API Gateway can be tedious to set up, aren't designed to work well with JavaScript and Node, and most of the quirks and gotchas aren't well documented. Claudia doesn't alter your project layout or abstract away the core AWS services; it just makes it easier to get started with them!

Master operating system development. FreeDOS Kernel explains the construction and operation of Pat Villani's DOS-C - a highly portable, single threaded operating system. Written in C and with system calls similar to MS-DOS, the FreeDOS kernel provides an excellent source code base for experimentation. Study it, modify it and use it without getting lost in the complexity of most microkernels. The book and companion disk include the full source code for an 80X86 kernel and support files. Achieve real platform independence with DOS compatibility. FreeDOS uses the de facto DOS hardware standards and provides binary compatibility for MS-DOS applications, compiles with Borland C, Microsoft C and other C cross-compilers without using their run-time libraries, and is the kernel provided by the FreeDOS community on the Internet. Provide embedded systems with full OS functionality. The FreeDOS kernel provides embedded systems applications with the functionality of larger operating systems, including file storage, embedded databases, and sophisticated device control. Simplify the design of your embedded systems by using your PC for development and then linking your own version of FreeDOS to create the application ROM.

Recently, the pressure for fast processing and efficient storage of large data with complexrelations increased beyond the capability of traditional databases. Typical examples include iPhone applications, computer aided design - both electrical and mechanical, biochemistry applications, and incremental compilers. Serialization, which is sometimes used in such situations is notoriously tedious and error prone.

In this book, Jiri Soukup and Petr Macha ek show in detail how to write programs which store their internal data automatically and transparently to disk. Together with special data structure libraries which treat relations among objects as first-class entities, and with a UML class-diagram generator, the core application code is much simplified. The benchmark chapter shows a typical example where persistent data is faster by the order of magnitude than with a traditional database, in both traversing and accessing the data.

The authors explore and exploit advanced features of object-oriented languages in a depth hardly seen in print before. Yet, you as a reader need only a basic knowledge of C++, Java, C#, or Objective C. These languages are quite similar with respect to persistency, and the authors explain their differences where necessary.

The book targets professional programmers working on any industry applications, it teaches you how to design your own persistent data or how to use the existing packages efficiently. Researchers in areas like language design, compiler construction, performance evaluation, and no-SQL applications will find a wealth of novel ideas and valuable implementation tips. Under http: //www.codefarms.com/bk, you will find a blog and other information, including a downloadable zip file with the sources of all the listings that are longer than just a few lines - ready to compile and run."

The conventional wisdom was that biology influenced mathematics and computer science. But a new approach has taken hold: that of transferring methods and tools from computer science to biology. The reverse trend is evident in Grammars and Automata for String Processing: From Mathematics and Computer Science to Biology and Back. The contributors address the structural (syntactical) view of the domain. Mathematical linguistics and computer science can offer various tools for modeling complex macromolecules and for analyzing and simulating biological issues. This collection is valuable for students and researchers in biology, computer science, and applied mathematics.

Mastering cluster technology-the linking of servers-is becoming increasingly important for application and system programmers and network designers, administrators, and managers. With Microsoft's Windows NT cluster server being the first to tie cluster technology with a major operating system, it appears destined to take a leadership position in the industry. Introduction to Microsoft Windows NT Cluster Server provides all you need to know to develop your abilities for this essential technology. The author provides both introductory and advanced material focused on the three basic functions: fault tolerant computing (failover), load balancing, and centralized administration and monitoring. He guides the reader from the basics of cluster servers, through Microsoft's cluster server set-up, communication, programming, and administration. Written for professionals who are familiar with the Windows NT operating system and have programming experience, Introduction to Microsoft Windows NT Cluster Server contains information instrumental in helping you achieve zero downtime.

In this international collection of papers there is a wealth of knowledge on artificial intelligence (AI) and cognitive science (CS) techniques applied to the problem of providing help systems mainly for the UNIX operating system. The research described here involves the representation of technical computer concepts, but also the representation of how users conceptualise such concepts. The collection looks at computational models and systems such as UC, Yucca, and OSCON programmed in languages such as Lisp, Prolog, OPS-5, and C which have been developed to provide UNIX help. These systems range from being menu-based to ones with natural language interfaces, some providing active help, intervening when they believe the user to have misconceptions, and some based on empirical studies of what users actually do while using UNIX. Further papers investigate planning and knowledge representation where the focus is on discovering what the user wants to do, and figuring out a way to do it, as well as representing the knowledge needed to do so. There is a significant focus on natural language dialogue where consultation systems can become active, metaphors, and users' mistaken beliefs. Much can be learned from seeing how AI and CS techniques can be investigated in depth while being applied to a real test-bed domain such as help on UNIX.

Although numerous sources document aspects of user-centered design, there are few references that consider how a designer transforms the information gathered about users and their work into an effective user interface design. This book explains just how designers bridge that gap. A group of leading experts in GUI design describe their methods in the context of specific design projects, and while the projects, processes, and methods vary considerably, the common theme is building a bridge between user requirements and user interface design.

Designed as a self-study guide, the book describes the real-world tradeoffs encountered in building a production-quality, platform-retargetable compiler. The authors examine the implementation of lcc, a production-quality, research-oriented retargetable compiler, designed at AT&T Bell Laboratories for the ANSI C programming language. The authors' innovative approach-a "literate program" that intermingles the text with the source code-uses a line-by-line explanation of the code to demonstrate how lcc is built.
