Potencjał blockchainu jest ogromny i zapewne wciąż nie znamy wszystkich jego możliwych zastosowań. Jest to dosyć nowa, dynamicznie rozwijająca się technologia, jednak już teraz dostrzegalne są pewne jej ograniczenia. Problemem jest na przykład skalowalność Bitcoina. Rozwiązaniem wydaje się Lightning Network (LN), protokół drugiej warstwy, który zapewnia niemal natychmiastowe transakcje w systemie Bitcoin. Umożliwia on również zwiększenie szybkości i prywatności zawieranych transakcji, pozwalając przy tym na zmniejszenie opłat. Ta książka jest przeznaczona dla osób, które chcą zrozumieć działanie Lightning Network i wykorzystać możliwości tej technologii we własnych aplikacjach. Z lektury tej pozycji skorzystają programiści, architekci systemowi i inżynierowie. Omówiono w niej podstawy funkcjonowania sieci LN i sposoby jej użycia w praktyce. Przedstawiono również zasady oprogramowywania węzłów Lightning, ich implementacji i konfiguracji, a także zagadnienia budowania kanałów płatności w systemie Bitcoin, obsługi kanałów i przekazywania płatności. Zaprezentowano też informacje dotyczące bezpieczeństwa i prywatności w sieci Lightning Network. Poszczególne zagadnienia zilustrowano praktycznymi przykładami kodu w językach Go, C++, Python oraz przy użyciu wiersza poleceń uniksowych systemów operacyjnych. W książce między innymi: technologia Lightning Network a skalowanie blockchainu standardy stosowane w Lightning Network warstwy zestawu protokołów Lightning Network portfele i węzły oraz ich obsługa kanały płatności Lightning, routing cebulowy i protokół plotkarski kanały płatności od nadawcy do odbiorcy w trybie off-chain Poznaj potencjał LN i zostań mistrzem technologii przyszłości!

Linux Device Drivers Development. Develop customized drivers for embedded Linux
John Madieu
Linux kernel is a complex, portable, modular and widely used piece of software, running on around 80% of servers and embedded systems in more than half of devices throughout the World. Device drivers play a critical role in how well a Linux system performs. As Linux has turned out to be one of the most popular operating systems used, the interest in developing proprietary device drivers is also increasing steadily.This book will initially help you understand the basics of drivers as well as prepare for the long journey through the Linux Kernel. This book then covers drivers development based on various Linux subsystems such as memory management, PWM, RTC, IIO, IRQ management, and so on. The book also offers a practical approach on direct memory access and network device drivers.By the end of this book, you will be comfortable with the concept of device driver development and will be in a position to write any device driver from scratch using the latest kernel version (v4.13 at the time of writing this book).
