 Название: Ruby on Rails Background Jobs with Sidekiq: Run Code Later without Complicating Your App
Автор: David Bryant Copeland
Издательство: The Pragmatic Programmers
Год: October 2023 (Version: P1.0)
Страниц: 106
Язык: английский
Формат: pdf, epub, mobi
Размер: 10.2 MB
Sidekiq is a reliable, well-supported, high-performing way to run code in the background of any Rails app. This book will give you a solid, practical foundation for creating resilient, well-tested, self-healing code that uses background jobs. You'll be able to simulate real-world failure modes and learn how to write idempotent code that can be safely run with Sidekiq. Whether you need to offload slow code out of a controller action, or make a flaky API call more fault tolerant, Sidekiq is the way to do that. One of the best ways to improve your Rails app's performance is to use background jobs with Sidekiq. While Sidekiq is easy to get set up, you need to do more than just move code around to reap the benefits. In this book, you'll get solutions to what sort of code should go into a Sidekiq job and how to manage those jobs. Even though you just need a few lines of code to run a Sidekiq job, there is quite a bit of complexity hiding in the shadows. A Rails app with Sidekiq jobs is really a distributed system. It has all the same challenges as a massive microservices-based architecture. | |

 Название: Hacks, Leaks, and Revelations: The Art of Analyzing Hacked and Leaked Data (Final)
Автор: Micah Lee
Издательство: No Starch Press
Год: 2024
Страниц: 544
Язык: английский
Формат: epub (true)
Размер: 15.3 MB
Unlock the internet’s treasure trove of public interest data with Hacks, Leaks, and Revelations by Micah Lee, an investigative reporter and security engineer. This hands-on guide blends real-world techniques for researching large datasets with lessons on coding, data authentication, and digital security. All of this is spiced up with gripping stories from the front lines of investigative journalism. Using Python or other programming languages, you can give your computer precise instructions for performing tasks that existing tools or shell scripts don’t allow. For example, you could write a Python script that scours a million pieces of video metadata to determine where the videos were filmed. In my experience, Python is also simpler, easier to understand, and less error-prone than shell scripts. This chapter provides a crash course on the fundamentals of Python programming. You’ll learn to write and execute Python scripts and use the interactive Python interpreter. You’ll also use Python to do math, define variables, work with strings and Boolean logic, loop through lists of items, and use functions. Future chapters rely on your understanding of these basic skills. | |

Well-designed applications run more efficiently, have fewer bugs, and are easier to revise and maintain. Learn the fundamentals of Object-Oriented Design by investigating good–and bad–code. Using an engaging “before-and-after” approach, Object-Oriented Software Design in C++ shows you exactly what bad software looks like and how to fix it with good design principles and patterns. In it, you’ll find Author, former NASA software engineer, and San Jose State University programming instructor Ronald Mak has written Object-Oriented Software Design in C++ as a masterclass for improving object-oriented programming skills. You’ll learn how to build the kind of high performance applications delivered by the pros, all using industry-proven design principles and patterns. The book’s accessible examples are written in C++ 17, but its universal principles can be applied to any object-oriented language. Object-Oriented Software Design in C++ is packed with 'before' program examples that show what not to do, followed by 'after' versions built with the benefits of good design. Each chapter is full of mentorship-style conversations that anticipate questions and help point out subtleties you might have missed. You’ll learn how to gather and analyze requirements so you’re building exactly what your client is looking for, discover how to utilize iterative development to backtrack mistakes, and revise your code to be as good as it can be. For beginning or intermediate C++ programmers looking to improve the way they code and build software. Examples are in C++ 17. | |
