"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.

Today, software engineers need to know not only how to program effectively but also how to develop proper engineering practices to make their codebase sustainable and healthy. This book emphasizes this difference between programming and software engineering.How can software engineers manage a living codebase that evolves and responds to changing requirements and demands over the length of its life? Based on their experience at Google, software engineers Titus Winters and Hyrum Wright, along with technical writer Tom Manshreck, present a candid and insightful look at how some of the worlds leading practitioners construct and maintain software. This book covers Googles unique engineering culture, processes, and tools and how these aspects contribute to the effectiveness of an engineering organization.Youll explore three fundamental principles that software organizations should keep in mind when designing, architecting, writing, and maintaining code:How time affects the sustainability of software and how to make your code resilient over timeHow scale affects the viability of software practices within an engineering organizationWhat trade-offs a typical engineer needs to make when evaluating design and development decisions

Most of the GNU Emacs integrated environment is written in the programming language called Emacs Lisp. The code written in this programming language is the software (the sets of instructions) that tell the computer what to do when you give it commands. Emacs is designed so that you can write new code in Emacs Lisp and easily install it as an extension to the editor. This introduction to Emacs Lisp is designed to get you started: to guide you in learning the fundamentals of programming, and more importantly, to show you how you can teach yourself to go further. This manual is available online for free at gnu.org. This manual is printed in grayscale.

Denne bog giver en introduktion til programmeringssproget Struktureret Tekst (ST) der benyttes i Programmerbare Logiske Controllere (PLC)Indhold:- Baggrund, fordele og udfordringer ved ST-programmering- Syntaks og grundlæggende ST-programmering- Stor guide til fornuftig navngivning af variabler- CTU, TOF, TON, CASE, STRUCT, ARRAY, STRING- Guide til opdeling i program moduler og funktioner- Mere end 90 PLC-kode eksempler i farver- FIFO, RND, 3D ARRAY, digitalt filter- Eksempler: Kom fra LADDER over til ST-programmering- Guide til løsning af programmeringsopgaverBogen går systematisk frem med beskrivelse af de grundlæggende ST-begreber og programmering, herunder tips, og med inddragelse af forfatterens 25 års praktiske erfaring.Der er mange steder uddybende forklaringer til PLC-koden og der er fokus på at læseren lærer at skrive robust, læsbar, struktureret og overskuelig PLC-kode. Desuden fokuseres på at kunne skrive PLC-kode, som ikke kræver en bestemt PLC-type og PLC-kode der kan genbruges, samt PLC-løsninger, der kan benyttes internationalt.Grundlaget for bogen er et materiale, som er udarbejdet løbende med feedback fra undervisere og studerende på automationsteknolog-uddannelsen hos Erhvervs-akademi Dania. Materialet er således løbende opdateret, så det giver svar på de spørgsmål og udfordringer, de studerende typisk har gennem deres studie.ST-programmering til PLC-styringer er fra omkring år 2010 begyndt at blive mere udbredt i Danmark, og siden år 2015 er mange virksomheder i Danmark begyndt udelukkende at levere PLC-styringer, hvor der benyttes ST som det foretrukne programmeringssprog. Dette kræver at flere medarbejdere kan ST og det er et af argumenterne, for at udgive denne bog.Bogen er primært udarbejdet til brug på den videregående fuldtidsuddannelse Automationsteknolog og deltidsuddannelsen Automation og Drift.

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.
