Julia 1.0 High Performance. Optimizations, distributed computing, multithreading, and GPU programming with Julia 1.0 and beyond - Second Edition

Avik Sengupta, Alan Edelman

Julia is a high-level, high-performance dynamic programming language for numerical computing. If you want to understand how to avoid bottlenecks and design your programs for the highest possible performance, then this book is for you. The book starts with how Julia uses type information to achieve its performance goals, and how to use multiple dispatches to help the compiler emit high-performance machine code. After that, you will learn how to analyze Julia programs and identify issues with time and memory consumption. We teach you how to use Julia's typing facilities accurately to write high-performance code and describe how the Julia compiler uses type information to create fast machine code. Moving ahead, you'll master design constraints and learn how to use the power of the GPU in your Julia code and compile Julia code directly to the GPU. Then, you'll learn how tasks and asynchronous IO help you create responsive programs and how to use shared memory multithreading in Julia. Toward the end, you will get a flavor of Julia's distributed computing capabilities and how to run Julia programs on a large distributed cluster.By the end of this book, you will have the ability to build large-scale, high-performance Julia applications, design systems with a focus on speed, and improve the performance of existing programs.

Roberto Ulloa

Mobiles and tablets have brought with them a dramatic change in the utility of applications. Compatibility has become essential, and this has increased the kind of interaction that users expect: gestures, multi-touches, animations, and magic pens. Kivy is an open source Python solution that covers these market needs with an easy-to-learn and rapid development approach. Kivy is growing fast and gaining attention as an alternative to the established developing platforms.Kivy: Interactive Applications in Python quickly introduces you to the Kivy development methodology. You will learn some examples of how to use many of the Kivy components, as well as understand how to integrate and combine them into big projects. This book serves as a reference guide and is organized in such a way that once finished, you will have already completed your first project.You will start by learning the Kivy Language for building User Interfaces (UI) and vector figures. We then proceed to the uses of Kivy events and properties to glue the UI with the application logic.You then go on to build an entire User Interface (UI) starting from a hand-made sketch. Furthermore, you will go on to understand how to use the canvas and drawing instructions to create different types of geometrical figures. Finally, you will be introduced to a big set of interactive and smooth features: transformations (scale, rotate, and translate), gestures, animations, scheduling tasks, and multi-touch elements.Kivy: Interactive Applications in Python expands your knowledge by introducing various components that improve the User Experience (UX). Towards the end of the book, you will be confident to utilize Kivy components and strategies to start any application or game you have in mind.

Kotlin for Enterprise Applications using Java EE. Develop, test, and troubleshoot enterprise applications and microservices with Kotlin and Java EE

As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.

Krótka historia informatyki

Ryszard Tadeusiewicz

Czy wiesz, że maszyny liczące znano już w starożytności, a pierwszy program komputerowy napisała córka Byrona Ada Lovelace? Mark I – komputer pierwszej generacji powstały w 1944 roku – miał 17 metrów długości, 2 metry wysokości i metr szerokości. Pierwszym polskim elektronicznym komputerem był XYZ, zbudowany w 1958 roku. Czy nigdy nie intrygowało cię, jak to wszystko się zaczęło? W dziejach ludzkości nie było innego procesu, który by w tak krótkim czasie w tak ogromnym stopniu przeobraził wszystkie obszary aktywności zawodowej i życia codziennego całych społeczności i pojedynczych ludzi! Jeszcze w połowie XX wieku na świecie było tylko kilka komputerów… A teraz? Ten ogromny postęp był możliwy dzięki pracy konkretnych ludzi, których nazwiska i dokonania warto poznać. Dowiedz się, jak Apple zrewolucjonizował rynek, jak rozwijały się układy scalone, jaką moc obliczeniową mają superkomputery i czemu służyły pierwsze sieci komputerowe. Oto Krótka historia informatyki! Ryszard Tadeusiewicz – profesor i były trzykrotny rektor AGH oraz prezes Krakowskiego Oddziału PAN. Członek PAU, Europejskiej Akademii Nauk oraz Akademii Inżynierskiej w Polsce. Wiceprezes Polskiego Stowarzyszenia Sztucznej Inteligencji i szeregu innych towarzystw naukowych. Członek honorowy Polskiego Towarzystwa Informatycznego, wyróżniony medalem 70-lecia polskiej informatyki za zasługi dla jej rozwoju. Doktor honoris causa 12 uczelni krajowych i zagranicznych.
