Linux in a Nutshell, 5th Edition
by Arnold Robbins Stephen Figgins Ellen Siever Aaron Weber Robert LoveOver the last few years, Linux has grown both as an operating system and a tool for personal and business use. Simultaneously becoming more user friendly and more powerful as a back-end system, Linux has achieved new plateaus: the newer filesystems have solidified, new commands and tools have appeared and become standard, and the desktop--including new desktop environments--have proved to be viable, stable, and readily accessible to even those who don't consider themselves computer gurus. Whether you're using Linux for personal software projects, for a small office or home office (often termed the SOHO environment), to provide services to a small group of colleagues, or to administer a site responsible for millions of email and web connections each day, you need quick access to information on a wide range of tools. This book covers all aspects of administering and making effective use of Linux systems. Among its topics are booting, package management, and revision control. But foremost in Linux in a Nutshell are the utilities and commands that make Linux one of the most powerful and flexible systems available. Now in its fifth edition, Linux in a Nutshell brings users up-to-date with the current state of Linux. Considered by many to be the most complete and authoritative command reference for Linux available, the book covers all substantial user, programming, administration, and networking commands for the most common Linux distributions. Comprehensive but concise, the fifth edition has been updated to cover new features of major Linux distributions. Configuration information for the rapidly growing commercial network services and community update services is one of the subjects covered for the first time. But that's just the beginning. The book covers editors, shells, and LILO and GRUB boot options. There's also coverage of Apache, Samba, Postfix, sendmail, CVS, Subversion, Emacs, vi, sed, gawk, and much more. Everything that system administrators, developers, and power users need to know about Linux is referenced here, and they will turn to this book again and again.

Linux iptables Pocket Reference: Firewalls, NAT & Accounting
by Gregor N. PurdyFirewalls, Network Address Translation (NAT), network logging and accounting are all provided by Linux's Netfilter system, also known by the name of the command used to administer it, iptables. The iptables interface is the most sophisticated ever offered onLinux and makes Linux an extremely flexible system for any kind of network filtering you might do. Large sets of filtering rules can be grouped in ways that makes it easy to test them and turn them on and off.Do you watch for all types of ICMP traffic--some of them quite dangerous? Can you take advantage of stateful filtering to simplify the management of TCP connections? Would you like to track how much traffic of various types you get?This pocket reference will help you at those critical moments when someone asks you to open or close a port in a hurry, either to enable some important traffic or to block an attack. The book will keep the subtle syntax straight and help you remember all the values you have to enter in order to be as secure as possible. The book has an introductory section that describes applications,followed by a reference/encyclopaedic section with all the matches and targets arranged alphabetically.

Linux: The Ultimate Guide
by Sufyan bin UzayrLinux is one of the most widely used operating systems. It was created to provide a free or low-cost operating system for personal computer users. Linus Torvalds published Linux on September 17, 1991, and it was written in the C programming language. It has since earned a reputation for being a high-performing and efficient system. This is a fairly comprehensive operating system that includes a graphical user interface (GUI), TCP/IP, the Emacs editor, and the X Window System, among other features. Debian, Ubuntu, Fedora, Red Hat Linux, SUSE Linux, Gentoo, Kali Linux, and Linux Mint are some of the finest Linux distributions. Linux is a very popular operating system today because of features such as multiuser operating system management, multitasking paradigm, multiprogramming concepts, and virtual memory. Many corporations and individuals, as well as firms such as Canonical, use Linux for their servers because of security concerns and positive feedback from the user community. Linux is also used in mobile devices, smart TVs, etc. Key Features: • A step-by-step approach to problem solving and skill development • A quick run-through of the basic concepts, in the form of a “crash course” • An advanced, hands-on core concepts, with a focus on real-world problems • An industry-level coding paradigm, practice-oriented explanatory approach • A special emphasis on writing clean and optimized code, with additional chapters focused on coding methodology
Liquid Metal Soft Machines: Principles and Applications (Topics in Mining, Metallurgy and Materials Engineering)
by Jing Liu Lei Sheng Zhi-Zhu HeThis book discusses the core principles and practical applications of a brand new machine category: liquid-metal soft machines and motors. After a brief introduction on the conventional soft robot and its allied materials, it presents the new conceptual liquid-metal machine, which revolutionizes existing rigid robots, both large and small. It outlines the typical features of the soft liquid-metal materials and describes the various transformation capabilities, mergence of separate metal droplets, self-rotation and planar locomotion of liquid-metal objects under external or internal mechanism. Further, it introduces a series of unusual phenomena discovered while developing the shape changeable smart soft machine and interprets the related mechanisms regarding the effects of the shape, size, voltage, orientation and geometries of the external fields to control the liquid-metal transformers. Moreover, the book illustrates typical strategies to construct a group of different advanced functional liquid-metal soft machines, since such machines or robots are hard to fabricate using rigid-metal or conventional materials. With highly significant fundamental and practical findings, this book is intended for researchers interested in establishing a general method for making future smart soft machine and accompanying robots.
Liquiditätsplanung: Das Steuerungstool für zukunftssicheres unternehmerisches Handeln – ein Praxisleitfaden

Es widmet sich einer möglichst prognosegenauen Abbildung der zukünftigen Zahlungsströme des laufenden operativen Geschäftsmodells. Aufgrund der Zusammenführung von Planungsrechnungen, rechtlichen Vereinbarungen des Debitoren- und Kreditorenmanagements und Prognoseverfahren ist der Liquiditätsplan im Planungsuniversum einzigartig und sichert bei konsequenter und richtiger Anwendung die Unternehmensexistenz. Ziel dieses Praxisleitfadens ist ein konzeptionell stringentes und gleichzeitig praktisch orientiertes Planungsmodell, das mit einer beherrschbaren Toleranz Aufschluss über die Entwicklung der Liquidität des Unternehmens gibt – sowohl dem Management als auch den Finanzverantwortlichen –, um es erfolgreich in die Zukunft zu führen.
Lisp in Small Pieces
by Christian QueinnecThis is a comprehensive account of the semantics and the implementation of the whole Lisp family of languages, namely Lisp, Scheme and related dialects. It describes 11 interpreters and 2 compilers, including very recent techniques of interpretation and compilation. The book is in two parts. The first starts from a simple evaluation function and enriches it with multiple name spaces, continuations and side-effects with commented variants, while at the same time the language used to define these features is reduced to a simple lambda-calculus. Denotational semantics is then naturally introduced. The second part focuses more on implementation techniques and discusses precompilation for fast interpretation: threaded code or bytecode; compilation towards C. Some extensions are also described such as dynamic evaluation, reflection, macros and objects. This will become the new standard reference for people wanting to know more about the Lisp family of languages: how they work, how they are implemented, what their variants are and why such variants exist. The full code is supplied (and also available over the Net). A large bibliography is given as well as a considerable number of exercises. Thus it may also be used by students to accompany second courses on Lisp or Scheme.
List of The Informed Brain in a Digital World
by National Academies Keck Future InitiativeDigital media provide humans with more access to information than ever before-a computer, tablet, or smartphone can all be used to access data online and users frequently have more than one device. However, as humans continue to venture into the digital frontier, it remains to be known whether access to seemingly unlimited information is actually helping us learn and solve complex problems, or ultimately creating more difficulty and confusion for individuals and societies by offering content overload that is not always meaningful. Throughout history, technology has changed the way humans interact with the world. Improvements in tools, language, industrial machines, and now digital information technology have shaped our minds and societies. There has always been access to more information than humans can handle, but the difference now lies in the ubiquity of the Internet and digital technology, and the incredible speed with which anyone with a computer can access and participate in seemingly infinite information exchange. Humans now live in a world where mobile digital technology is everywhere, from the classroom and the doctor's office to public transportation and even the dinner table. This paradigm shift in technology comes with tremendous benefits and risks. Interdisciplinary Research (IDR) Teams at the 2012 National Academies Keck Futures Initiative Conference on The Informed Brain in the Digital World explored common rewards and dangers to Humans among various fields that are being greatly impacted by the Internet and the rapid evolution of digital technology. Keynote speaker Clifford Nass of Stanford University opened the dialogue by offering insight into what we already know about how the "information overload" of the digital world may be affecting our brains. Nass presented the idea of the "media budget," which states that when a new media emerges, it takes time away from other media in a daily time budget. When additional media appear and there is no time left in a person's daily media budget, people begin to "double book" media time. Personal computers, tablets, and smartphones make it easy to use several media simultaneously, and according to Nass, this double-booking of media can result in chronic multitasking, which effects how people store and manage memory. Although current fast-paced work and learning environments often encourage multitasking, research shows that such multitasking is inefficient, decreases productivity, and may hinder cognitive function. National Academies Keck Future Initiative: The Informed Brain in a Digital World summarizes the happenings of this conference.
