Imagine being able to create accurate maps that look how you want them to, and use them on the Web or in print, for free. OpenStreetMap allows exactly that, with no restrictions on how or where you use your maps. OpenStreetMap is perfect for businesses that want to include maps on their website or in publications without paying high fees. With this book in hand you have the power to make, alter, and use this geographical data in a collaborative way from anywhere on the Earth.OpenStreetMap was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways. This book will allow you to take control of your own maps and use them smoothly. This book introduces the reader to the OpenStreetMap project and shows you how to participate in the project, and make use of the data it provides. No prior knowledge of the project is assumed, and technical details are kept to a minimum.In this book, you'll learn how easy it is to add your neighborhood to OpenStreetMap using inexpensive GPS equipment, or even no GPS at all. You'll find out how to communicate with other mappers working in the same area, and where to find more information about how to map the world around you.Once you have your area mapped, you'll learn how to turn this information into maps, whether for use in print or online, large or small, and with the details you want shown. The book describes several rendering methods, each suited to different types of map, and takes you through a tutorial on each one.

Oprogramowanie szyte na miarę. Jak rozmawiać z klientem, który nie wie, czego chce
Michał Bartyzel
Jeśli zapytasz stu ludzi, jak wyobrażają sobie piłkę, każdy powie Ci co innego. Ile osób, tyle różnych spojrzeń na każdy temat. Dlaczego więc zakładasz, że dokładnie wiesz, czego potrzebuje Twój klient? Dlaczego zakładasz, że Twój klient wie, co masz na myśli, gdy proponujesz mu wizję nowego systemu informatycznego??? Między biznesem a IT W wynikach badań na temat przyczyn porażek projektów IT najczęściej przewijają się trzy najważniejsze czynniki: problemy komunikacyjne, niekompletne wymagania i brak zaangażowania użytkowników. Projekty nie udają się wcale nie dlatego, że temat jest trudny i nie ze względu na kłopoty techniczne czy finanse. Najwięcej problemów powstaje wtedy, gdy klient i usługodawca nie są w stanie się porozumieć. Punktem wyjścia dla każdego systemu są wymagania klientów i użytkowników. Wiele już napisano o zarządzaniu wymaganiami, klasyfikowaniu wymagań, diagramach i niezliczonej ilości narzędzi informatycznych. Jednak aby wymaganiami zarządzać, trzeba je najpierw zebrać. Ta książka koncentruje się na etapie kompletowania wymagań. Podsuwa sposoby takiego zbierania informacji, aby w trakcie wywiadu z klientem lub użytkownikiem bardzo dokładnie zrozumieć ich problemy i potrzeby. To jedyny sposób, aby stworzyć dla nich oprogramowanie na miarę. W branży IT jak dogmat powtarza się przekonanie, że "klient nie wie, czego chce". Przyszedł czas, aby się z nim zmierzyć.

Przy tworzeniu projektów informatycznych ludzie muszą umieć się dogadać. Brak wspólnej wizji, świadomości istnienia innych perspektyw czy zrozumienia potrzeb pomiędzy współpracującymi stronami zawsze prowadzi do porażki. Tym bardziej w środowisku Agile, gdzie ludzie ze świata biznesu i developerzy pracują razem, zdolność do skutecznej komunikacji staje się niezwykle ważna. Można nawet powiedzieć, że umiejętności miękkie mają tam większe znaczenie niż umiejętności techniczne, które łatwiej zdobyć. Skuteczna komunikacja to taka sama umiejętność jak jazda samochodem czy programowanie. Michał Bartyzel doskonale to pokazuje, rozkładając cały proces rozmowy na proste elementy. Dzięki temu czytelnik może nauczyć się rozpoznawać wzorce i dopasowywać odpowiednie techniki do kontekstu rozmowy. Autor posługuje się prostym i zrozumiałym językiem, uważnie wybiera najważniejsze aspekty tematów z pogranicza psychologii i coachingu. Narzędzia, które czytelnik dostaje do ręki, można od razu wykorzystać w pracy. Oprogramowanie szyte na miarę wyróżnia się spośród pozycji o podobnej tematyce skupieniem na ludzkiej stronie tematu - w miejsce proponowania kolejnych szablonów i metod. Nie jest to kolejne tłumaczenie z języka angielskiego, ani próba zastosowania amerykańskich technik w polskich realiach. Liczne przykłady zaczerpnięte prosto z życia pokazują, jakie błędy popełniamy w codziennych rozmowach i jak można ich uniknąć. Gwarantuję, że niejeden raz uśmiechniesz się podczas czytania zapisów rozmów. Jest to książka promująca pierwszy punkt Manifestu Agile: ludzie i ich interakcje ponad procesy i narzędzia. Polecam ją gorąco wszystkim osobom zaangażowanym w pracę nad projektami informatycznymi wytwarzanymi w relacji klient-dostawca albo na wewnętrzne potrzeby organizacji.

Citrix XenDesktop is a suite of desktop virtualization tools designed to provide users with fast and convenient access to their Windows desktops and applications through any device. Virtual desktops mean that rather than setting up hundreds or thousands of individual computers in an enterprise, companies can instead opt to create servers with large amounts of memory, disk, and processing resources, and use virtualization to offer these resources to end users. The result of this is that users are provided with an experience that appears to be identical to having an individual desktop PC. Each user has some disk space, processor time, and memory allocated to them, as though it is present on their own physical machine, when in reality, the resources are physically present on a centralized server.This book starts by answering the basic questions you need to ask when considering XenDesktop, followed by methods of how you can properly size your server infrastructure for XenDesktop. You’ll discover how to optimize the virtual machines used in XenDesktop, how to optimize your network for XenDesktop, and how to optimize the hypervisor and the cloud. You’ll also learn how to monitor XenDesktop to maximize performance.By the end of the book, you will be able to plan, design, build, and deploy high performance XenDesktop Virtualization systems in enterprises. You will also know how to monitor and maintain your systems to ensure smooth operation.
