Foundations of Blockchain. The pathway to cryptocurrencies and decentralized blockchain applications
Koshik Raj
Blockchain technology is a combination of three popular concepts: cryptography, peer-to-peer networking, and game theory. This book is for anyone who wants to dive into blockchain from first principles and learn how decentralized applications and cryptocurrencies really work.This book begins with an overview of blockchain technology, including key definitions, its purposes and characteristics, so you can assess the full potential of blockchain. All essential aspects of cryptography are then presented, as the backbone of blockchain. For readers who want to study the underlying algorithms of blockchain, you’ll see Python implementations throughout.You’ll then learn how blockchain architecture can create decentralized applications. You’ll see how blockchain achieves decentralization through peer-to-peer networking, and how a simple blockchain can be built in a P2P network. You’ll learn how these elements can implement a cryptocurrency such as Bitcoin, and the wider applications of blockchain work through smart contracts. Blockchain optimization techniques, and blockchain security strategies are then presented. To complete this foundation, we consider blockchain applications in the financial and non-financial sectors, and also analyze the future of blockchain. A study of blockchain use cases includes supply chains, payment systems, crowdfunding, and DAOs, which rounds out your foundation in blockchain technology.

Komponuj zjawiskowe animacje w JavaScripcie! Najlepsze „ściągawki” dla JavaScriptu, czyli wszystko o frameworkach, bibliotekach i platformach programistycznych Zastosowanie gotowych fragmentów kodu — kontrolek, przycisków, galerii fotografii i formularzy kontaktowych Sposoby tworzenia animacji i efektów specjalnych Stworzenie od zera kodu zaawansowanej aplikacji czy strony WWW jest dziś praktycznie niemożliwe — nie mówiąc już o tym, że niepotrzebne i zdecydowanie zbyt czasochłonne. Znacznie lepiej jest skorzystać z fragmentów gotowego kodu o określonym działaniu. W erze dominacji animowanych, interaktywnych i dynamicznych witryn internetowych oraz wymagających użytkowników warto poszerzać swoją wiedzę na temat animacji i efektów możliwych do uzyskania dzięki różnym frameworkom, bibliotekom i platformom programistycznym. W tej książce znajdziesz mnóstwo cennych wiadomości o wykorzystaniu najlepszych, najbardziej innowacyjnych źródeł gotowego kodu dla JavaScriptu. Składa się ona z sześciu rozdziałów — każdy z nich traktuje o wykorzystaniu jednego z tych źródeł w zakresie: transformacji 2D i 3D elementów HTML, sortowania, przeciągania lub przemieszczania elementów HTML wzdłuż osi lub po ścieżce (krzywej) ruchu, a także symulowania ruchu jednostajnego lub zmiennego. Oprócz tego opisano tu sterowanie procesem odtwarzania animacji poprzez kontrolowanie czasu jej trwania i manipulowanie kolejnością wykonywania poszczególnych sekwencji.

Spark allows you to quickly extract actionable insights from large amounts of data, on a real-time basis, making it an essential tool in many modern businesses. Frank has packed this book with over 15 interactive, fun-filled examples relevant to the real world, and he will empower you to understand the Spark ecosystem and implement production-grade real-time Spark projects with ease.
FreeCAD. Solid Modeling with the power of Python with this book and
Brad Collette, Daniel Falck
FreeCAD is a general purpose platform for CAD development. It can be extended to use different workbenches to solve different problems. Targeted squarely at the engineering community, FreeCAD is an open source design application built to be extended. Python, the powerful scripting language, is woven deeply into FreeCAD's DNA and gives users unprecedented power to automate and invent. FreeCAD [How-to] is a lean, fast tour of FreeCAD's major workbenches and design philosophy. The reader will get a hands-on introduction to several modeling techniques and learn how Python makes macro automation and design possible.FreeCAD allows users to design in a variety of ways; from drawing 2D designs as lines and circles to combining primitive solids into complex 3D shapes. Objects can even be created or modified by code you write in Python. FreeCAD even allows power users to extend the application itself with new dialogs, panels, and scripts. This book will not only show you how to get started using FreeCAD in a traditional GUI mode, but will teach you how to harness its powerful scripting language for more power.

The Open Source pioneers have proved during the past few decades that their code and projects can indeed be more solid and popular than commercial alternatives. With data networks always expanding in size and complexity FreeRADIUS is at the forefront of controlling access to and tracking network usage. Although many vendors have tried to produce better products, FreeRADIUS has proved over time why it is the champion RADIUS server. This book will reveal everything you need to know to get started with using FreeRADIUS.FreeRADIUS has always been a back-room boy. It's not easy to measure the size or number of deployments world-wide but all indications show that it can outnumber any commercial alternatives available. This essential server is part of ISPs, universities, and many corporate networks, helping to control access and measure usage. It is a solid, flexible, and powerful piece of software, but can be a mystery to a newcomer.FreeRADIUS Beginner's Guide is a friend of newcomers to RADIUS and FreeRADIUS. It covers the most popular Linux distributions of today, CentOS, SUSE, and Ubuntu, and discusses all the important aspects of FreeRADIUS deployment: Installing, configuring and testing; security concerns and limitations; LDAP and Active Directory integration.It contains plenty of practical exercises that will help you with everything from installation to the more advanced configurations like LDAP and Active Directory integration. It will help you understand authentication, authorization and accounting in FreeRADIUS. It uses many practical step-by-step examples, which are discussed in detail to lead you to a thorough understanding of the FreeRADIUS server as well as the RADIUS protocol. A quiz at the end of each chapter validates your understanding.Not only can FreeRADIUS be used to monitor and limit the network usage of individual users; but large deployments are possible with realms and fail-over functionality. FreeRADIUS can work alone or be part of a chain where the server is a proxy for other institution's users forwarding requests to their servers. FreeRADIUS features one of the most versatile and comprehensive Extensible Authentication Protocol (EAP) implementations. EAP is an essential requirement to implement enterprise WiFi security. FreeRADIUS Beginner's Guide covers all of these aspects.
