Big Data. Najlepsze praktyki budowy skalowalnych systemów obsługi danych w czasie rzeczywistym

Nathan Marz, James Warren

Obsługa aplikacji, które operują na ogromnych zbiorach danych, czyli na przykład portali społecznościowych, przekracza możliwości zwykłych relacyjnych baz. Praca ze złożonymi zbiorami danych wymaga architektury obejmującej wielomaszynowe klastry, dzięki którym możliwe jest przechowywanie i przesyłanie informacji praktycznie dowolnej wielkości. Architektura taka powinna dodatkowo być prosta w użyciu, niezawodna i skalowalna. Dzięki tej książce nauczysz się budować tego rodzaju architekturę. Zapoznasz się z technologią wykorzystywania klastrów maszyn. Dowiesz się, jak działają narzędzia przeznaczone specjalnie do przechwytywania i analizy danych na wielką skalę. W książce zaprezentowano łatwe do zrozumienia podejście do obsługi systemów wielkich zbiorów danych, które mogą być budowane i uruchamiane przez niewielki zespół. Nie zabrakło też wyczerpującego opisu praktycznej implementacji systemu Big Data z wykorzystaniem rzeczywistego przykładu. W tej książce znajdziesz: teoretyczne podstawy koncepcji systemów Big Data wskazówki umożliwiające optymalne wykorzystanie zasobów do obsługi danych wybór technik przetwarzania i obsługi wielkich ilości danych w czasie rzeczywistym zagadnienia dotyczące baz danych NoSQL, przetwarzania strumieniowego i zarządzania złożonością obliczeń przyrostowych informacje o praktycznym stosowaniu takich narzędzi jak Hadoop, Cassandra i Storm wskazówki umożliwiające poszerzenie wiedzy o zwykłych bazach danych Big Data — to skalowalność i prostota obsługi wielkich ilości danych!

Blender 3D Printing by Example. Learn to use Blender's modeling tools for 3D printing by creating 4 projects

Vicky Somma

Blender is an open-source modeling and animation program popular in the 3D printing community. 3D printing brings along different considerations than animation and virtual reality.This book walks you through four projects to learn using Blender for 3D Printing, giving you information that you need to know to create high-quality 3D printed objects.The book starts with two jewelry projects-- a pendant of a silhouette and a bracelet with custom text. We then explore architectural modeling as you learn to makes a figurine from photos of a home. The final project, a human hand, illustrates how Blender can be used for organic models and how colors can be added to the design.You will learn modeling for 3D printing with the help of these projects. Whether you plan to print at-home or use a service bureau, you’ll start by understanding design requirements. The book begins with simple projects to get you started with 3D modeling basics and the tools available in Blender. As the book progresses, you’ll get exposed to more robust mesh modeling techniques, modifiers, and Blender shortcuts. By the time you reach your final project, you’ll be ready for organic modeling and learning how to add colors. In the final section, you’ll learn how to check for and correct common modeling issues to ensure the 3D printer can make your idea a reality!
