Modeling and Simulation of Invasive Applications and Architectures (Computer Architecture and Design Methodologies)
by Sascha Roloff Frank Hannig Jürgen TeichThis book covers two main topics: First, novel fast and flexible simulation techniques for modern heterogeneous NoC-based multi-core architectures. These are implemented in the full-system simulator called InvadeSIM and designed to study the dynamic behavior of hundreds of parallel application programs running on such architectures while competing for resources. Second, a novel actor-oriented programming library called ActorX10, which allows to formally model parallel streaming applications by actor graphs and to analyze predictable execution behavior as part of so-called hybrid mapping approaches, which are used to guarantee real-time requirements of such applications at design time independent from dynamic workloads by a combination of static analysis and dynamic embedding.
RT Essentials: Managing Your Team and Projects with Request Tracker
by Dave Rolsky Darren Chamberlain Richard Foley Robert Spier Jesse VincentIn a typical organization, there's always plenty that to do such as: pay vendors, invoice customers, answer customer inquiries, and fix bugs in hardware or software. You need to know who wants what and keep track of what is left to do. This is where a ticketing system comes in. A ticketing system allows you to check the status of various tasks: when they were requested, who requested them and why, when they were completed, and more. RT is a high-level, open source ticketing system efficiently enabling a group of people to manage tasks, issues, and requests submitted by a community of users. RT Essentials, co-written by one of the RT's original core developers, Jesse Vincent, starts off with a quick background lesson about ticketing systems and then shows you how to install and configure RT. This comprehensive guide explains how to perform day-to-day tasks to turn your RT server into a highly useful tracking tool. One way it does this is by examining how a company could use RT to manage its internal processes. Advanced chapters focus on developing add-on tools and utilities using Perl and Mason. There's also chapter filled with suggested uses for RT inside your organization. No matter what kind of data your organization tracks--from sales inquiries to security incidents or anything in between--RT Essentials helps you use RT to provide order when you need it most.
Embedding Perl in HTML with Mason
by Dave Rolsky Ken WilliamsMason doesn't aim to be the one true Perl-based templating system for building web sites, but it's led many programmers to abandon their custom solutions when they've seen how much easier using Mason can be. It's a powerful, open source, Perl-based web site development and delivery engine, with features that make it an ideal backend for high load sites serving dynamic content. Mason uses a concept called components: a mix of HTML, Perl, and special Mason commands. These components can be entire web pages, or bits of HTML that can be embedded in top-level components. Shared and reusable, these components greatly simplify site maintenance: when you change a shared component, you instantly change all pages that refer to it. Although using Mason isn't difficult, creating a Mason-based site can be tricky. Embedding Perl in HTML with Mason , written by members of Mason's core development team, shows you how to take advantage of Mason's strengths while avoiding the obstacles that inexperienced users may encounter. Mason's unique features, when used properly, can streamline the design of a web site or application. This concise book covers these features from several angles, and includes a study of the authors' sample site where these features are used. Embedding Perl in HTML with Mason shows you how to create large, complex, dynamically driven web sites that look good and are a snap to maintain. You'll learn how to visualize multiple Mason-based solutions to any given problem and select among them. The book covers the latest line of Mason development 1.1x, which has many new features, including line number reporting based on source files, sub-requests, and easier use as a CGI. The only book to cover this important tool, Embedding Perl in HTML with Mason is essential reading for any Perl programmer who wants to simplify web site design. Learn how to use Mason, and you'll spend more time making things work, and less time reinventing the wheel.

Access Database Design & Programming: Creating Programmable Database Applications with Access 97, 2000, 2002 & 2003 (Nutshell Handbooks)
by Steven RomanAccess Database Design & Programming takes you behind the details of the Access interface, focusing on the general knowledge necessary for Access power users or developers to create effective database applications. When using software products with graphical interfaces, we frequently focus so much on the interface that we forget about the general concepts that allow us to understand and use the software effectively. In particular, this book focuses on three areas:Database design. The book provides an enjoyable, informative overview of database design that carefully shows you how to normalize tables to eliminate redundancy without losing data. Queries. The book examines multi-table queries (i.e.,various types of joins) and shows how to implement them indirectly by using the Access interface or directly by using Access SQL. Programming. The book examines the VBA integrated development environment (IDE). It then goes on to provide an excellent introduction to Data Access Objects (DAO), ActiveX Data Objects (ADO), and ADO Extensions for Data Definition and Security (ADOX). These sections serve as a handy introduction and primer for basic database operations,such as modifying a table under program control, dynamically adding and deleting a record, and repositioning a record pointer. The concluding chapter focuses on common programming problems, such as computing running sums and comparing two sets. Unlike other Access books that take the long, detailed approach to every topic of concern to Access programmers, Access Database Design &Programming instead focuses on the core concepts, enabling programmers to develop solid, effective database applications. This book also serves as a 'second course' in Access that provides a relatively experienced Access user who is new to programming with the frequently overlooked techniques necessary to develop successfully in the Microsoft Access environment. Anyone interested in learning Access in depth, rather than just scraping the surface, will enjoy and benefit immensely from reading this book.

Make: FPGAs
by David RomanoWhat if you could use software to design hardware? Not just any hardware--imagine specifying the behavior of a complex parallel computer, sending it to a chip, and having it run on that chip--all without any manufacturing? With Field-Programmable Gate Arrays (FPGAs), you can design such a machine with your mouse and keyboard. When you deploy it to the FPGA, it immediately takes on the behavior that you defined. Want to create something that behaves like a display driver integrated circuit? How about a CPU with an instruction set you dreamed up? Or your very own Bitcoin miner You can do all this with FPGAs. Because you're not writing programs--rather, you're designing a chip whose sole purpose is to do what you tell it--it's faster than anything you can do in code. With Make: FPGAs, you'll learn how to break down problems into something that can be solved on an FPGA, design the logic that will run on your FPGA, and hook up electronic components to create finished projects.
