Harness the power of Linux to create versatile and robust embedded solutions
Key Features:
Learn how to develop and configure robust embedded Linux devices
Explore the new features of Linux 5.4 and the Yocto Project 3.1 (Dunfell)
Discover different ways to debug and profile your code in both user space and the Linux kernel
Book Description:
Embedded Linux runs many of the devices we use every day. From smart TVs and Wi-Fi routers to test equipment and industrial controllers, all of them have Linux at their heart. The Linux OS is one of the foundational technologies comprising the core of the Internet of Things (IoT).
This book starts by breaking down the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the kernel, and the root filesystem. After that, you will learn how to create each of these elements from scratch and automate the process using Buildroot and the Yocto Project. As you progress, the book explains how to implement an effective storage strategy for flash memory chips and install updates to a device remotely once it's deployed. You'll also learn about the key aspects of writing code for embedded Linux, such as how to access hardware from apps, the implications of writing multi-threaded code, and techniques to manage memory in an efficient way. The final chapters demonstrate how to debug your code, whether it resides in apps or in the Linux kernel itself. You'll also cover the different tracers and profilers that are available for Linux so that you can quickly pinpoint any performance bottlenecks in your system.
By the end of this Linux book, you'll be able to create efficient and secure embedded devices using Linux.
What You Will Learn:
Use Buildroot and the Yocto Project to create embedded Linux systems
Troubleshoot BitBake build failures and streamline your Yocto development workflow
Update IoT devices securely in the field using Mender or balena
Prototype peripheral additions by reading schematics, modifying device trees, soldering breakout boards, and probing pins with a logic analyzer
Interact with hardware without having to write kernel device drivers
Divide your system up into services supervised by BusyBox runit
Debug devices remotely using GDB and measure the performance of systems using tools such as perf, ftrace, eBPF, and Callgrind
Who this book is for:
If you're a systems software engineer or system administrator who wants to learn Linux implementation on embedded devices, then this book is for you. Embedded systems engineers accustomed to programming for low-power microcontrollers can use this book to help make the leap to high-speed systems on chips that can run Linux. Anyone responsible for developing new hardware that needs to run Linux will also find this book useful. Basic working knowledge of the POSIX standard, C programming, and shell scripting is assumed.

Описание: BiSL, Business information Services Library, is het framework voor business informatiemanagement. Sinds de introductie van BiSL is het model uitgegroeid tot de standaard op het vakgebied in Nederland. BiSL biedt een structuur en leidraad voor business informatiemanagement. BiSL legt verbindingen tussen operationeel functioneel beheer en strategisch informatiemanagement en geeft handvatten voor (verdere) professionalisering van business informatiemanagement.Al deze onderwerpen komen aan de orde in dit trainingsmateriaal dat ondersteuning biedt bij de voorbereiding op het officiele APMG BiSL Foundation examen. In combinatie met de toelichting bij de trainingsmaterialen door uw docenttrainer kunt u zich optimaal op het examen voorbereiden.Deze training gaat in op de uitgangspunten van BiSL en het met BiSL gedefinieerde proces- framework. Aan de orde komen de uitgangspunten en het framework als geheel, de uitvoerende processen (opgesplitst naar gebruiksbeheer, functionaliteitenbeheer en verbindende processen), de sturende processen en de richtinggevende processen.Er is veel ruimte voor uitwisseling van ervaringen, waarbij steeds wordt teruggegaan naar de theorie. De courseware bestaat uit: hand-outs, oefeningen en artikelen plus een oefenexamen.Doelgroep: informatiemanagement, medewerkers van functioneel beheer en IT-ers die de vraagzijde beter willen leren kennen.De presentaties lichten de theorie toe. Met de oefenopdrachten kunt u zich gedurende de training de stof verder eigen maken. De vragen van het oefenexamen geven inzicht in wat u op het examen kunt verwachten.Dit trainingsmateriaal sluit volledig aan op de uitgave BiSL, een framework voor business informatiemanagement, 3e editie. In deze 3e editie van het framework zijn in hoofdlijnen de volgende wijzigingen doorgevoerd ten opzichte van de vorige editie:"¢ Er is een nieuw proces beschreven: Operationele ketenafstemming.¢ De rangschikking van de processen in de sturende laag is gewijzigd.¢ Er is meer aandacht voor onderwerpen als Big data, Cloud, beveiliging en ketens.¢ Er wordt aandacht geschonken aan enkele andere frameworks, modellen en standaarden.¢ De positie en context van business informatiemanagement is duidelijker beschreven.Ten opzichte van de vorige uitgave van dit trainingsmateriaal zijn slechts op de noodzakelijke inhoudelijke punten aanpassingen doorgevoerd, waarmee de aansluiting op de nieuwe editie van het framework is geborgd. Qua opzet/opbouw, zowel van de lesstof als van de diverse opdrachten en oefeningen, is het lesmateriaal ongewijzigd gebleven.

Описание: Excavations carried out by Oxford Archaeology at Berryfields to the north-west of Aylesbury in Buckinghamshire uncovered the remains of a middle Iron Age settlement and the agricultural hinterland of the nucleated Roman settlement of Fleet Marston, situated on the major Roman road of Akeman Street. This volume describes the results of the fieldwork and analysis of an exceptional range of the artefactual and environmental evidence, including timber piles, which supported a bridge that carried the Roman road over the River Thame, and a wooden basket, chickens’ eggs and many other objects ritually deposited into a waterlogged pit in the late Roman period. In addition, the volume presents evidence for a long-lived late prehistoric territorial boundary, malting and brewing and other roadside trades and crafts, as well as funerary activity, comprising roadside burials and a possible pyre site. It also reveals the importance of livestock, especially horses, in the middle Iron Age and Roman economies. Crucially, the volume draws on the findings to shed light on the character of Roman Fleet Marston, which hitherto has been known only from chance finds. Evidence from Berryfields and other sites in the area shows that over time, Fleet Marston found itself at the intersection of several routeways that took travellers into the countryside and on to major towns. Its position at this important crossroads, together with hundreds of coins and other finds, potentially identifies the settlement as a market-place or administrative centre with extensive trade connections, a role that would be continued in Aylesbury in the medieval period and to the present day.

Описание: This book is about the how of project management and about how you as a project manager can use a proactive attitude to stay in control, even during difficult situations. It shows you how to become an influencer of the path to the end result, of your environment, of your team and of your effectiveness.Today`s project managers have to meet high expectations. Challenging goals, a strong focus on cost management and lead times, serving the interests of different stakeholders and many dependencies between subprojects make project management an increasingly complex affair - especially in an environment where change and uncertainty have become the new norm. In addition, the creative abilities of knowledge workers have to be optimally utilised, which requires less hierarchical organisational structures and more multidisciplinary collaboration. Having the right project management skills is therefore essential at virtually every level of an organisation.As a result of these challenges, there is a growing demand for comprehensive methods and the popularity of Agile is on the rise. On the other hand, the increased complexity also results in a need for simplicity. That is what this book is about: going back to the basics, being able to combine useful elements from different methods and focusing on the most important aspect of all: the person behind the project manager!This book contains a wealth of practical descriptions with useful examples and anecdotes. Readers are constantly stimulated to internalise the essence and put it into practice in a manner that suits their own style and personality. That is the only way to keep at it, be successful and make others believe in you!The book consists of three parts. Part 1 (chapters 1 to 4) describes how to set up and manage a project. The focus is on the basic principles, the essence of taking control, creating structure and using Agile behavior. Part 2 (chapters 5 and 6) explains how to draw up a plan and schedule in small steps, which results in improved completeness, coordination and support. Finally, part 3 (chapters 7 to 10) covers how to manage the project execution: how to realize the path to the final goal with a strict PDCA rhythm, how to evaluate the quality of interim results and how to keep your team and environment motivated.

Описание: Blockchain technology has come a long way since the initial vision published by Satoshi Nakamoto in 2008. Big buzz words like "bitcoin," "blockchain," and "cryptocurrency" are everywhere. Companies and governments have started to use blockchain technology in earnest and will increasingly do so for the foreseeable future. This book takes an in-depth look at blockchain technology and how users can take advantage of its potential. Since its initial conception, blockchain has encompassed both a social promise and new technology. Originally proposed as a solution for Bitcoin`s cryptocurrency record-keeping system, blockchains are now used to store the records of all types of applications. Core services we all depend on like the transfer of money, voting, land records, IP rights, and identity all rely on intermediaries. Blockchain software has begun taking the place of these antiquated systems. The software becomes the trusted record-keeping system, and the rules programed into the software become the intermediaries. This book explains the fundamentals of blockchain technology and assumes that the reader has little to no knowledge of the subject. Topics are explained as simply as possible, while not obscuring details that may affect the reader. It also gives the reader insight into the critical differences in blockchain software and will provide them with a basic understanding of how and why these systems work. After reading this book, the reader will be able to speak with confidence on the topic, know key differences in technology. The reader will also have critical insight into blockchain software`s inherent limitations and shortcomings. This book is also the definitive guide to the Blockchain Technology Foundation (BTF) exam from EXIN. It will prepare the reader for the test, and each chapter ends with review questions for extra guidance in preparing for the exam.
