repeater: 01110010 ...
by Andrew McEwanSHORTLISTED FOR THE 2013 GERALD LAMPAND MEMORIAL AWARDrepeater is a poetic investigation into the coding, function, language, and structure of computer programming. Using the ASCII 8-bit binary code as an acrostic, each lower-case letter of the alphabet is arranged alongside the lines of the title poem. As a result, this poem "programs" an investigation of layered and digitalized language that is coded into the heart of the code itself. Appendixes to this code form supplementary studies, and deviate into additional problems and concepts at the convergence of poetry and computer programming. Ultimately, repeater reveals what happens when the creative variability of poetry is "inputted" into the rigid binaric structure of computer language.
sEMG-based Control Strategy for a Hand Exoskeleton System (Springer Theses)
by Nicola SeccianiThis book reports on the design and testing of an sEMG-based control strategy for a fully-wearable low-cost hand exoskeleton. It describes in detail the modifications carried out to the electronics of a previous prototype, covering in turn the implementation of an innovative sEMG classifier for predicting the wearer's motor intention and driving the exoskeleton accordingly. While similar classifier have been widely used for motor intention prediction, their application to wearable device control has been neglected so far. Thus, this book fills a gap in the literature providing readers with extensive information and a source of inspiration for the future design and control of medical and assistive devices.

sed & awk, Second Edition
by Arnold Robbins Dale Doughertysed & awk describes two text manipulation programs that are mainstays of the UNIX programmer's toolbox. This edition covers the sed and awk programs as they are mandated by the POSIX standard and includes discussion of the GNU versions of these programs.
sed & awk: UNIX Power Tools
by Arnold Robbins Dale Doughertysed & awk describes two text processing programs that are mainstays of the UNIX programmer's toolbox.sed is a "stream editor" for editing streams of text that might be too large to edit as a single file, or that might be generated on the fly as part of a larger data processing step. The most common operation done with sed is substitution, replacing one block of text with another.awk is a complete programming language. Unlike many conventional languages, awk is "data driven" -- you specify what kind of data you are interested in and the operations to be performed when that data is found. awk does many things for you, including automatically opening and closing data files, reading records, breaking the records up into fields, and counting the records. While awk provides the features of most conventional programming languages, it also includes some unconventional features, such as extended regular expression matching and associative arrays. sed & awk describes both programs in detail and includes a chapter of example sed and awk scripts.This edition covers features of sed and awk that are mandated by the POSIX standard. This most notably affects awk, where POSIX standardized a new variable, CONVFMT, and new functions, toupper() and tolower(). The CONVFMT variable specifies the conversion format to use when converting numbers to strings (awk used to use OFMT for this purpose). The toupper() and tolower() functions each take a (presumably mixed case) string argument and return a new version of the string with all letters translated to the corresponding case.In addition, this edition covers GNU sed, newly available since the first edition. It also updates the first edition coverage of Bell Labs nawk and GNU awk (gawk), covers mawk, an additional freely available implementation of awk, and briefly discusses three commercial versions of awk, MKS awk, Thompson Automation awk (tawk), and Videosoft (VSAwk).
sed and awk Pocket Reference: Text Processing with Regular Expressions
by Arnold RobbinsFor people who create and modify text files, sed and awk are power tools for editing. sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs.The sed & awk Pocket Reference is a companion volume to sed & awk, Second Edition, Unix in a Nutshell, Third Edition, and Effective awk Programming, Third Edition. This new edition has expanded coverage of gawk (GNU awk), and includes sections on:An overview of sed and awk?s command line syntaxAlphabetical summaries of commands, including nawk and gawkProfiling with pgawkCoprocesses and sockets with gawkInternationalization with gawkA listing of resources for sed and awk usersThis small book is a handy reference guide to the information presented in the larger volumes. It presents a concise summary of regular expressions and pattern matching, and summaries of sed and awk.Arnold Robbins, an Atlanta native now happily living in Israel, is a professional programmer and technical author and coauthor of various O'Reilly Unix titles. He has been working with Unix systems since 1980, and currently maintains gawk and its documentation.
sendmail
by Bryan Costales Claus Assmann George Jansen Gregory Neil ShapiroA classic O'Reilly title since 1993, sendmail now covers Versions 8.10 through 8.14 of this email routing program, including dozens of new features, options, and macros. This edition also takes a more nuts-and-bolts approach than its predecessors. It includes both an administration handbook and a reference guide that provide you with clear options for installing, configuring and managing sendmail's latest versions and companion programs. The sendmail program has withstood the test of time because of its ability to solve the mail-routing needs of all sites large or small, complex or simple. But it's also difficult to configure and even more difficult to understand. That's why this book has proven valuable since the dawn of email. With it, you will be able to configure the program to meet any need, so that you never again have to call in a sendmail guru to bail you out.sendmail includes the following sections: Some Basics is especially useful for people new to the program. It covers the basic concepts underlying mail delivery and the roles sendmail plays in that deliveryAdministration covers all aspects of handling sendmail, from downloading and installing new releases to managing mailing lists and aliasesConfiguration Reference contains a heavily cross-referenced guide for configuring and tuning sendmail. Every arcane detail of sendmail is listed alphabeticallyAppendices contain more detail about sendmail than you may ever need This edition also includes new material on SSL and AUTH and a new chapter on Mitlers. If you're interested in what has changed since the last edition, one appendix categorizes the many improvements of sendmail's intervening versions by chapter, complete with references to the appropriate sections and page numbers in the book. With sendmail, system administrators, programmers, network engineers, and even inexperienced users will be able to match this challenging but necessary utility to the needs of their network.
sendmail 8.13 Companion
by Bryan Costales Claus Assmann George Jansen Gregory ShapiroIf you had a list of the words used to describe sendmail, they'd probably include reliable, flexible, configurable, complex, monolithic, and daunting. But you're not likely to find the word easy. Even seasoned sendmail pros are sometimes frustrated by the intricacies of sendmail's configuration files. With a little determination and the help of a good reference book, like sendmail , Third Edition, you can master this demanding program. But when there's a significant point release, like sendmail V8.13, where do you turn? An excellent companion to our popular sendmail , Third Edition, the sendmail 8.13 Companion provides a timely way to document the improvements in V8.13 in parallel with its release. The book highlights the important changes in the latest update to sendmail, pointing out not just what is handy or nice to have, but what's critical in getting the best behavior from sendmail. This is especially important now that spam is on the rise, and because mobile technology requires roving laptops to use encrypted connections. Not surprisingly, many of the changes and additions to V8.13 have been driven by the ongoing fight against spam. Anyone concerned about spam--and who isn't?--will benefit greatly by upgrading to V8.13 sendmail. Among its many enhancements, V8.13 includes new routines that support the SPF sending site authentication standard (in the Milter library), simultaneous connection control, high connection rate control, and finer tuning of SASL parameters. The additions to the Milter library, alone, make upgrading worthwhile, but sendmail's connection control makes it a no-brainer. The key to understanding them is the sendmail 8.13 Companion . The book is divided into twenty-five chapters that parallel the chapters in the third edition of the sendmail book. For instance, if you're interested in Options configuration (Chapter 24 in sendmail), you'll turn to Chapter 24 in your companion volume to find out what's new in V8.13. For a simple dot release (8.12 to 8.13), V8.13 sendmail has added more features, options, and fundamental changes than any other single dot release has included. If you need to set up or manage sendmail, you'll want this companion volume close at hand. Even if you aren't ready to upgrade to V8.13, you'll find the key to understanding them is the sendmail 8.13 Companion a useful guide to understanding and staying current with the latest changes in sendmail.
sendmail Cookbook: Administering, Securing & Spam-Fighting
by Craig HuntMore often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology.Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem.Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances.The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:Delivering and forwarding mailRelayingMasqueradingRouting mailControlling spamStrong authenticationSecuring the mail transportManaging the queueSecuring sendmailsendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread.
