"e;The computer world is like an intellectual Wild West, in which you can shoot anyone you wish with your ideas, if you're willing to risk the consequences. "e; --from Hackers & Painters: Big Ideas from the Computer Age, by Paul GrahamWe are living in the computer age, in a world increasingly designed and engineered by computer programmers and software designers, by people who call themselves hackers. Who are these people, what motivates them, and why should you care?Consider these facts: Everything around us is turning into computers. Your typewriter is gone, replaced by a computer. Your phone has turned into a computer. So has your camera. Soon your TV will. Your car was not only designed on computers, but has more processing power in it than a room-sized mainframe did in 1970. Letters, encyclopedias, newspapers, and even your local store are being replaced by the Internet.Hackers & Painters: Big Ideas from the Computer Age, by Paul Graham, explains this world and the motivations of the people who occupy it. In clear, thoughtful prose that draws on illuminating historical examples, Graham takes readers on an unflinching exploration into what he calls "e;an intellectual Wild West."e;The ideas discussed in this book will have a powerful and lasting impact on how we think, how we work, how we develop technology, and how we live. Topics include the importance of beauty in software design, how to make wealth, heresy and free speech, the programming language renaissance, the open-source movement, digital design, internet startups, and more.

Mere end halvdelen af de virksomheder, der har outsourcet på it-området oplever, at de ikke får indfriet deres forventninger til aftalen. Over 30 % har hjemtaget en eller flere it-opgaver, de har haft outsourcet. Det kræver både tid og ressourcer at gennemføre en it-outsourcing proces, og det er tilsvarende en tids- og ressourcekrævende at genopbygge kompetence i egen organisation, hvis outsourcing opgaver skal hjemtages. Derfor ligger der et stort potentiale i at få it-outsourcing aftalerne til at fungere bedre.Bogen går ind analyserer dette dilemma og kommer med en række forslag til, hvordan man opnår succes med sin it-outsourcing. Den henvender sig til de virksomheder og organisationer, der overvejer it-outsourcing eller allerede har outsourcet på it-området, samt til management konsulenter og jurister, der rådgiver på området og til it-outsourcing leverandørerne. De bøger, der er skrevet om it-outsourcing tager typisk udgangspunkt i de kommercielle og strategiske overvejelser omkring outsourcing. Der mangler en bog, der adresserer de udfordringer, der er i dag på it-outsourcing området, og hvor løsningerne tager udgangspunktet i refleksioner over praktiske erfaringer på området.Kim Lyster har i over 20 år arbejdet med it-outsourcing for virksomheder som Dan Computer Management (i dag CSC), Olivetti, Wang Global, Getronics, Eterra, EDS, Ementor og KMD.Forfatteren har indgået outsourcing aftaler med mere end 50 virksomheder og organisationer. Han har i den forbindelse haft mulighed for at følge de fleste af opgaverne over tid og set hvor det fungerede godt, og hvor der var udfordringer. Samtidig har forfatteren deltaget i en række faglige fora og netværk på området og har holdt indlæg på en række konferencer om it-outsourcing. Det er de praktiske erfaringer fra de mange års arbejde med it-outsourcing, der er baggrunden for mange af refleksionerne, forfatteren giver udtryk for i bogen.

This book about Visual Basic for Applications (VBA) is different from other books describing VBA for serveral reasons. It is fine-tuned for business applications and in particular business students and it includes business relevant examples. Already in the first chapters the reader is introduced to a variety of different VBA tools, which will enable him or her to write small useful business related programs. In the following chapters the same tools - and more - are presented in a more detailed and rigid way.VBA Programming in Business Economicsis structured as a textbook where each chapter is concluded with a number of exercises which can be used for individual training or as a base for computer-lab teaching. The book's webpage provides case projects that can be used to learn how to combine the material of the book in a larger context. In the situations where examples, exercises, and case projects require knowledge of specific theoretical background, this is provided as short summaries on the books webpage.Besides covering the basic programming, the book also covers programming topics that are more business related: How to use the Excel Solver from within the VBA code, how to perform simulations, and how to construct user forms and make them work with the program. Learning to make useful programs requires more than just writing a number of if- and while statements. Therefore the book also provides a chapter that illustrates how to design and structure a program.In all, this book is a hands-on-guide on VBA for graduate students in Business Economics.

From Wharton professor and author of the popular One Useful Thing Substack newsletter Ethan Mollick comes the definitive playbook for working, learning, and living in the new age of AISomething new entered our world in November 2022 — the first general purpose AI that could pass for a human and do the kinds of creative, innovative work that only humans could do previously. Wharton professor Ethan Mollick immediately understood what ChatGPT meant: after millions of years on our own, humans had developed a kind of co-intelligence that could augment, or even replace, human thinking. Through his writing, speaking, and teaching, Mollick has become one of the most prominent and provocative explainers of AI, focusing on the practical aspects of how these new tools for thought can transform our world. In Co-Intelligence, Mollick urges us to engage with AI as co-worker, co-teacher, and coach. He assesses its profound impact on business and education, using dozens of real-time examples of AI in action. Co-Intelligence shows what it means to think and work together with smart machines, and why it's imperative that we master that skill. Mollick challenges us to utilize AI's enormous power without losing our identity, to learn from it without being misled, and to harness its gifts to create a better human future. Wide ranging, hugely thought-provoking, optimistic, and lucid, Co-Intelligence reveals the promise and power of this new era.

In July 1976 a new type of Integrated Circuit was released into the world and over half a century later it is still in production. This device is the Zilog Z80 processor and its longevity surely makes it one of the most successful electronic devices ever produced.This device spawned the rapid development of multitude of relatively low cost personal computer systems which would previously have been impossible to produce.This book is aimed at anyone who has ever wanted to design their own Z80 based computer system. From first principles to a fully working computer it delves into circuit design at the discrete logic level. Each circuit is fully described in detail and although this computer has many of the features found in many vintage computer systems it avoids the use of large scale integration devices. Each circuit is constructed using discrete logic gates to provide a fully immersive development experience.
