Now in full color, the 10th anniversary edition of this classic book takes you deep into the influences that underlie modern video games, and examines the elements they share with traditional games such as checkers. At the heart of his exploration, veteran game designer Raph Koster takes a close look at the concept of fun and why it's the most vital element in any game. Why do some games become boring quickly, while others remain fun for years? How do games serve as fundamental and powerful learning tools? Whether you're a game developer, dedicated gamer, or curious observer, this illustrated, fully updated edition helps you understand what drives this major cultural force, and inspires you to take it further. You'll discover that: Games play into our innate ability to seek patterns and solve puzzles Most successful games are built upon the same elements Slightly more females than males now play games Many games still teach primitive survival skills Fictional dressing for modern games is more developed than the conceptual elements Truly creative designers seldom use other games for inspiration Games are beginning to evolve beyond their prehistoric origins

Linux systemadministration från grunden lär dig allt du behöver för att komma igång att administrera Linuxdatorer, vare sig det är servrar på internet eller bärbara datorer. Eller varför inte en Raspberry Pi för mätningar? Linux är viktigare och större än någonsin. Det finns överallt. På servrarna som tillhandahåller många av de webbsidor du surfar på. Det finns i stora beräkningskluster, telefoner, bilar och underhållningssystem. I början av boken får du grundläggande kunskaper om hur du arbetar med Linux. Här lär du dig bland annat hur Linux är uppbyggt, användbara kommandon, filsystemets uppbyggnad och hur du redigerar filer i både Nano och Vi. Därefter lär du dig att skapa nya användare och grupper i systemet. Du lär dig också hur du sätter filrättigheter i Linux. Mot mitten av boken lär du dig mer avancerade ämnen, så som textbearbetning, att skriva egna skalskript, administrera tjänster, processhantering, nätverkskonfiguration och mycket mer. Boken fungerar för de flesta Linuxutgåvor. Men bland annat kapitlen om pakethantering och nätverkskonfiguration har skrivits speciellt för Red Hat, CentOS, Fedora, Debian och Ubuntu. Till varje kapitel finns det övningsuppgifter så att du själv kan träna på det du lärt dig. En del av övningsuppgifterna går utanför boken, och du måste då själv leta upp rätt kommandon i den inbyggda manualen. Jack-Benny Persson har många års erfarenhet av främst Linux- och FreeBSD-system, men också av programmering. Intresset för datorer började redan i början av 1990-talet och har sedan dess bara fortsatt. På gymnasiet läste han el & elektronik. Från 2013–2015 studerade han till Linux Systemspecialist vid EC-Utbildning. Senast har han studerat journalistiskt skrivande. Han har tidigare gett ut böckerna "Grunderna i programmering" och "C-programmering i Linux, macOS, BSD och Solaris". Han har också producerat videokurser om Linux.

Det mesta arbetet i Windows utgår från Start-menyn som du nu hittar i mitten av skärmen. På Start-menyn finns de appar och program som du oftast använder tillsammans med Utforskaren, Inställningar, e-post och alla andra installerade appar. Med den här boken lär du dig effektivt grunderna i Windows 11. Du får lära dig att öppna och använda appar, hantera fönster, arbeta i skrivbordsprogram samt surfa på webben. Vi tittar även på hur du gör inställningar för att anpassa Windows och Start-menyn så att det ska fungera på bästa sätt för just dig. I boken går vi också igenom hur du arbetar med mappar och filer, samt använder apparna E-post och Kalender. Vi tittar dessutom på hur du använder appar för att visa foton och lyssna på musik. Slutligen kommer du få lära dig att installera appar och enheter på datorn. Till boken hör många övningar i varierande svårighetsgrad. Filerna till dessa laddar du ner utan kostnad från vår webbplats docendo.se, där finns även lösningsförslag till övningarna i pdf-format. Boken fungerar även utmärkt för dig som har engelsk version, då läromedlet har kompletterats med de engelska kommandona.

Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will LearnIncorporate automated unit testing into an embedded projectDesign and build functional simulators for an embedded projectWrite production-quality software when hardware is not availableUse the Data Model architectural pattern to create a highly decoupled design and implementationUnderstand the importance of defining the software architecture before implementation starts and how to do itDiscover why documentation is essential for an embedded projectUse finite state machines in embedded projectsWho This Book Is ForMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.

Have you ever had any of these problems?

Have you been surprised to discover your backup tapes are blank? Ever spent a year launching a new service only to be told the users hate it? Do you have more incoming support requests than you can handle? Do you spend more time fixing problems than building the next awesome thing? Have you suffered from a botched migration of thousands of users to a new service? Does your company rely on a computer that, if it died, can’t be rebuilt? Is your network a fragile mess that breaks any time you try to improve it? Is there a periodic “hell month” that happens twice a year? Twelve times a year? Do you find out about problems when your users call you to complain? Does your corporate “Change Review Board” terrify you? Does each division of your company have their own broken way of doing things? Do you fear that automation will replace you, or break more than it fixes? Are you underpaid and overworked?

No vague “management speak” or empty platitudes. This comprehensive guide provides real solutions that prevent these problems and more!

Firewalls, Network Address Translation (NAT), and 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 on Linux 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 listings of all iptables options are divided into those suitable for firewalling, accounting, and NAT.
