Is Ruby Pass-by-Value Or Pass-by-Reference?
This article will delve into Ruby internals to explain how parameters are passed into functions. As you will see, it is not immediate to say if Ruby passes parameters by value or by reference, but understanding how this works will help you to write better programs.

Software Systems Need Skin in the Game
Consequential decisions need to be taken by the people who pay for the consequences, by the people with skin in the game, and modern software practices need to reinforce this idea. On-call engineering is the quintessential modern engineering practice to create skin in the software development game.

Boosting WebAssembly Performance with SIMD and Multi-Threading
Early implementations of WebAssembly's SIMD and multi-threading proposals show that WebAssembly is narrowing the gap with native performance, by using SIMD instructions and multicore CPUs. Significant performance improvements have been observed in compute-intensive tasks (machine-learning, bio-informatics, scientific computing).

The Future of Data Engineering
Chris Riccomini examines the current and future states of the art in data pipelines, data streaming, and data warehousing. He presents a six-stage evolution that data ecosystems follow, from a simple monolith to a complex data-microwarehouse architecture as the data engineers who manage them solve problems and clarify their roles as infrastructure engineers, rather than data stewards.

Microservices from the Trenches: Lessons, Benefits, Challenges, and Mistakes
Nicky Wrightson, from Skyscanner, hosted a panel at QCon London with participants who have moved from the monolith to microservices and in some cases back again. They share their experience with microservices on production, and also strong opinions on monorepos, on operating distributed systems, and on the best way to structure an organization to make a success of this architecture.

Who is on the Team?
Ahmad Fahmy and Cesario Ramos take the changes to the new Scrum Guide as an opportunity to explore what it means to be "on a team." They draw on research to create an ACID test to differentiate who is on the team and who isn't. They discuss different mental models around the idea of a team with the hopes that you take this opportunity to discuss and elevate the roles within your organization.

Testing Quarkus Web Applications: Component & Integration Tests
Quarkus is a full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and native compilation. Instead of reinventing the wheel, Quarkus uses well-known enterprise-grade frameworks backed by standards/specifications and makes them compilable to a binary using Graal VM. This article focuses on using some of the Quarkus testing facilities.
