Learn how to build a GraphQL API on top of a Rails application with this step-by-step guide. GraphQL is seen as a successor to REST APIs. GraphQL allows you to define a strictly typed API and to query for only the information you want, with none of the stuff you don't. This book will also show you how to make those types defined in your backend API flow through to your frontend code, defining clea

クラウド・コンピューティングは、完全に管理されたプラットフォーム、即時のスケー リング、自動最適化、さらには自動ヒーリング操作、秒単位の課金、事前学習済み の機械学習モデル、グローバルに分散したトランザクションデータストアなどを提 供できる素晴らしいリソースだ。また、クラウドは、組織がスピードの経済で競争す る事を可能にする重要な技術でもある。それゆえに、多くのエンタープライズがそ のような機能を利用したいと考えるのも不思議ではない。 しかし、エンタープライズ全体をクラウドに移行させることは、ボタンを押すだけで 済むような簡単なものではない。レガシー・アプリケーションを単にリフト& シフト するだけでは、期待通りの効果は得られないだろうし、クラウドで最適に動作する ようにアプリケーションのアーキテクチャを再設計するのは、膨大なコストがかか る可能性がある。さらに、クラウド技術から十分な恩恵

Stephan leads the product infrastructure engineering team at Gusto. Gusto has quite a bit of Ruby on Rails in the software behind their offerings and provides the perfect ground for the analysis of complex applications due to "Payroll" being both a deep and very wide domain. And Gusto is a lot more than payroll. Stephan is the author of Component-based Rails Applications in which he lays out the p

A Practical Guide to Testing in DevOps Japanese EditionDevOpsにおけるテストについて事例を交えて紹介した一冊
This book explains and illustrates how to implement Domain-Driven Design, Command Query Responsibility Segregation and Event Sourcing. The goal is to build software that is behavior-rich, event-based, problem-centric, reactive, scalable and well-designed. Domain-Driven Design is a way to build software that focuses on the problem to solve and its associated knowledge areas. Command Query Responsib
Important: this is the First Edition of the book. * Consider buying Functional Design and Architecture (Second Edition) by Manning instead. * See also my new book Pragmatic Type-Level Design. FDaA is a fundamental book about Software Design in Haskell and other functional languages. The main idea of this book is to provide a comprehensive source of knowledge, and a complete methodology for buildin
『Agile Testing Condensed』は、アジャイルにおいてどのような考えでテストを行うべきなのか簡潔に書かれています。JanetとLisaは、読者が理解できるように、20年間のアジャイルテストの経験から知識を抽出して表現しました。 - テストとQAの専門家がアジャイルチームでどのように貢献するか - アジャイルサイクルにテスト活動をフィットさせるにはどうすればよいか - いつ、誰の責任で、様々なテスト活動を完了させるのか - テストエンジニアがアジャイル開発チームの他のメンバーと関わるにはどうすればよいか - デリバリーチームの全員が継続的なテストに参加するにはどうすればよいか - 視覚的なモデルを使ってテスト活動を計画するにはどうすればよいか - 短いイテレーションや継続的なデリバリーに対してテストが「追いつく」にはどうすればよいか - テストの有効性を評価し、継続的に改善

Practical FP in Scala: A hands-on approach, is a book for intermediate to advanced Scala developers. Aimed at those who understand functional effects, referential transparency and the benefits of functional programming to some extent but who are missing some pieces to put all these concepts together to build a large application in a time-constrained manner. Throughout the chapters we will design,
Why Version? Have you ever done a big bang release? You schedule a maintenance window, carefully take down the system, release the new software, and… pray. I will never do a big bang release again. What scares me is not what happens if the release does not work, but what happens if it does not work and yet still appears to. Most developers, even those working through big bang releases, have dealt
Team change will happen whether we like it or not. People will come and go from our teams. Our companies might double in size or even get acquired. We can catalyze team change to reduce the risk of attrition, learning and career stagnation and the development of knowledge silos. Dynamic Reteaming describes practices for effective reteaming as well as antipatterns. In this book you'll learn how to
Interpretable Machine Learning is a comprehensive guide to making machine learning models interpretable "Pretty convinced this is the best book out there on the subject" – Brian Lewis, Data Scientist at Cornerstone Research Summary This book covers a range of interpretability methods, from inherently interpretable models to methods that can make any model interpretable, such as SHAP, LIME, and per
Sandy might best be described somewhere between independent researcher and voluntarily-unemployed bum. At the ripe old age of 27 he decided to quit his highly-lucrative engineering job and decide to focus more on living than on grinding for the man. It's what you might call a work in progress. He regularly writes about Haskell and Agda at reasonablypolymorphic.com. Preface Acknowledgments Introduc
As organisations shift to a culture of intense collaboration and rapid delivery, the expectations on testers are changing. What does testing look like in an environment with automated build and deployment pipelines? How does appetite for risk change once a product can be tested in production? Who should testers look to connect with across the organisation and how can they work together effectively
“Love is wise; hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don’t like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolut
This book is for the typical Scala developer, probably with a Java background, who is both sceptical and curious about the Functional Programming (FP) paradigm. This book justifies every concept with practical examples, including writing a web application. Frequently Asked Questions Q: How does it compare to the red book? A: This book is blue. Q: Where can I buy a physical copy? A: Hardback books

A Boy Who Wanted To Create Worlds Once there was a boy who fell in love with this magical device that could bring things to life inside a glaring screen. He spent endless hours exploring imaginary worlds, fighting strange creatures, shooting pixelated spaceships, racing boxy cars. The boy kept pondering. “How is this made? I want to create my own worlds…”. Then he discovered programming. “I can fi

1. Introduction The Python Programming language has been around for a long time. Guido van Rossum started development work on the first version in 1989, and it has since grown to become one of the more popular languages used in a wide range of applications from graphical interfaces to finance and data analysis. This write-up looks at the nuts and bolts of the Python interpreter. It targets CPython
Acknowledgements Mike First and foremost I would like to express my thanks to Mike Bostock, the driving force behind d3.js. His efforts are tireless and his altruism in making his work open and available to the masses is inspiring.

I am helping teams and companies to develop brilliant solutions to complex problems. Sometimes this involves writing software. Sometimes this involves working with people. I like both ways, especially when it leads me into unexplored territories. I've been coding since 1982, experimenting since ...forever?
