Raspberry Pi Pico W
The Raspberry Pi Pico and Pico W are based on the fast, efficient, and low-cost dual-core ARM Cortex M0+ RP2040 microcontroller chip running at up to 133 MHz and sporting 264 KB of SRAM and 2 MB of Flash memory. Besides spacious memory, the Pico and Pico W offer many GPIO pins, and popular peripheral interface modules like ADC, SPI, I2C, UART, PWM, timing modules, a hardware debug interface, and an internal temperature sensor.The Raspberry Pi Pico W additionally includes an on-board Infineon CYW43439 Bluetooth and Wi-Fi chipset. At the time of writing this book, the Bluetooth firmware was not yet available. Wi-Fi is however fully supported at 2.4 GHz using the 802.11b/g/n protocols.This book is an introduction to using the Raspberry Pi Pico W in conjunction with the MicroPython programming language. The Thonny development environment (IDE) is used in all of the 60+ working and tested projects covering the following topics:> Installing the MicroPython on Raspberry Pi Pico using a Raspberry Pi or a PC> Timer interrupts and external interrupts> Analogue-to-digital converter (ADC) projects> Using the internal temperature sensor and external sensor chips> Using the internal temperature sensor and external temperature sensor chips> Datalogging projects> PWM, UART, I2C, and SPI projects> Using Bluetooth, WiFi, and apps to communicate with smartphones> Digital-to-analogue converter (DAC) projectsAll projects are tried & tested. They can be implemented on both the Raspberry Pi Pico and Raspberry Pi Pico W, although the Wi-Fi- based subjects will run on the Pico W only. Basic programming and electronics experience are required to follow the projects. Brief descriptions, block diagrams, detailed circuit diagrams, and full MicroPython program listings are given for all projects. The full program listings of all the projects discussed in the book may be downloaded free of charge www.elektor.com/20335.Prof Dogan Ibrahim has a BSc, Hons. degree in Electronic Engineering, an MSc degree in Automatic Control Engineering, and a PhD degree in Digital Signal Processing.Dogan has worked in many industrial organizations before he returned to academic life. He is the author of over 70 technical books and has published over 200 technical articles on electronics, microprocessors, microcontrollers, and related fields.

Five Lines of Code
Refactoring ist die Kunst, bestehenden Code so zu verbessern, dass der Wert von Software langfristig erhalten bleibt. Das Ergebnis des Vorgangs ist als Clean Code bekannt – aber wie kommen Sie dahin? Christian Clausen legt hier eine ganz neuartige Schule des Refactorings vor, die Sie Schritt für Schritt anleitet. Das Vorgehen eignet sich für alle OOP-Sprachen. Die gut lesbaren Beispiele in TypeScript sind in einem Stil gehalten, der insbesondere Java- und C#- Entwickler*innen vertraut sein dürfte. Ein zweispaltiges Vorher-Nachher-Layout mit zeilengenauen Codekommentaren macht jeden Arbeitsschritt hervorragend nachvollziehbar. So gelingt Ihr Refactoring sicher!

RISC-V Assembly Language Programming using ESP32-C3 and QEMU
With the availability of free and open source C/C++ compilers today, you might wonder why someone would be interested in assembler language. What is so compelling about the RISC-V Instruction Set Architecture (ISA)? How does RISC-V differ from existing architectures? And most importantly, how do we gain experience with the RISC-V without a major investment? Is there affordable hardware available?The availability of the Espressif ESP32-C3 chip provides a way to get hands-on experience with RISC-V. The open sourced QEMU emulator adds a 64-bit experience in RISC-V under Linux. These are just two ways for the student and enthusiast alike to explore RISC-V in this book.The projects in this book are boiled down to the barest essentials to keep the assembly language concepts clear and simple. In this manner you will have "aha!" moments rather than puzzling about something difficult. The focus in this book is about learning how to write RISC-V assembly language code without getting bogged down. As you work your way through this tutorial, you'll build up small demonstration programs to be run and tested. Often the result is some simple printed messages to prove a concept. Once you've mastered these basic concepts, you will be well equipped to apply assembly language in larger projects.Warren Gay is a datablocks.net senior software developer, writing Linux internet servers in C++. He got involved with electronics at an early age, and since then he has built microcomputers and has worked with MC68HC705, AVR, STM32, ESP32 and ARM computers, just to name a few.

Secure Web Application Development
Cyberattacks are becoming more commonplace and the Open Web Application Security Project (OWASP), estimates 94% of sites have flaws in their access control alone. Attacks evolve to work around new defenses, and defenses must evolve to remain effective. Developers need to understand the fundamentals of attacks and defenses in order to comprehend new techniques as they become available. This book teaches you how to write secure web applications.The focus is highlighting how hackers attack applications along with a broad arsenal of defenses. This will enable you to pick appropriate techniques to close vulnerabilities while still providing users with their needed functionality.Topics covered include:* A framework for deciding what needs to be protected and how strongly* Configuring services such as databases and web servers* Safe use of HTTP methods such as GET, POST, etc, cookies and use of HTTPS* Safe REST APIs* Server-side attacks and defenses such as injection and cross-site scripting* Client-side attacks and defenses such as cross-site request forgery* Security techniques such as CORS, CSP* Password management, authentication and authorization, including OAuth2* Best practices for dangerous operations such as password change and reset* Use of third-party components and supply chain security (Git, CI/CD etc)WHAT YOU'LL LEARN** Review the defenses that can used to prevent attacks* Model risks to better understand what to defend and how* Choose appropriate techniques to defend against attacks* Implement defenses in Python/Django applicationsWHO THIS BOOK IS FOR* Developers who already know how to build web applications but need to know more about security* Non-professional software engineers, such as scientists, who must develop web tools and want to make their algorithms available to a wider audience.* Engineers and managers who are responsible for their product/company technical security policyMATTHEW BAKER is the Head of Scientific Software and Data Management at ETH Zurich, Switzerland’s leading science and technology university, He leads a team of engineers developing custom software to support STEM research projects, as well as teaches computer science short courses. Having over 25 years of experience developing software, he has worked as a developer, systems administrator, project manager and consultant in various sectors from banking and insurance, science and engineering, to military intelligence.1.

R 4 Data Science Quick Reference
In this handy, quick reference book you'll be introduced to several R data science packages, with examples of how to use each of them. All concepts will be covered concisely, with many illustrative examples using the following APIs: readr, dibble, forecasts, lubridate, stringr, tidyr, magnittr, dplyr, purrr, ggplot2, modelr, and more.With R 4 Data Science Quick Reference, you'll have the code, APIs, and insights to write data science-based applications in the R programming language. You'll also be able to carry out data analysis. All source code used in the book is freely available on GitHub..WHAT YOU'LL LEARN* Implement applicable R 4 programming language specification features* Import data with readr* Work with categories using forcats, time and dates with lubridate, and strings with stringr* Format data using tidyr and then transform that data using magrittr and dplyr* Write functions with R for data science, data mining, and analytics-based applications* Visualize data with ggplot2 and fit data to models using modelrWHO THIS BOOK IS FORProgrammers new to R's data science, data mining, and analytics packages. Some prior coding experience with R in general is recommended. Thomas Mailund is an associate professor at Aarhus University, Denmark. He has a background in math and computer science. For the last decade, his main focus has been on genetics and evolutionary studies, particularly comparative genomics, speciation, and gene flow between emerging species. He has published Beginning Data Science in R, Functional Programming in R, and Metaprogramming in R with Apress as well as other books on R and C programming.1. Introduction2. Importing Data: readr3.
