The article discusses best practices for designing application schemas that are resilient and effective in offline environments. It emphasizes the importance of an "offline-first" strategy, particularly because real-world usage often occurs in conditions with poor connectivity. Key concepts include the necessity of lifecycle fields (like created_at, updated_at, and deleted_at) for tracking data accurately and supporting sync operations. The author warns against common pitfalls, such as relying too heavily on Object-Relational Mappers (ORMs) and misusing caching technologies

The author created a website, https://lowbackgroundsteel.ai/, in March 2023 as a resource hub for online content that hasn't been tainted by AI-generated material. The concept, termed "Low-background Steel," refers to uncontaminated metal, specifically steel and lead that is free from radioactive isotopes, typically sourced from ships sunk before 1945. The site aims to catalog text, images, and videos produced before the proliferation of AI content in 2022. Currently, it includes

The content discusses a scenario related to copy construction in C++ involving inheritance. It explains that the compiler determines whether a class (such as `Derived<int>`) is copy-constructible by checking for the presence of a non-deleted copy constructor. Although `Derived<T>` has a declared copy constructor, it relies on the copy constructor of a non-copyable base class (`Base<int>`), leading to an error when instantiation is attempted. The text highlights a discrepancy where the compiler considers `Derived

The author reflects on the rise of Docker and container technology since 2018, noting that it has become the standard for application deployment with backend apps incorporating Dockerfiles and Kubernetes YAMLs. Despite acknowledging the utility of containers for environment setup and safe execution, the author believes they are an overly complex solution that could be addressed by operating systems. The article explores alternatives to containerization, highlighting that containers are primarily used for cloud app deployment. Docker solves the issues of setting up stable environments with a consistent dependency tree

In this weekly newsletter, Stephane discusses the evolution of engineering management. Initially, small engineering teams had no formal leadership structure, often reporting to various stakeholders like PMs or founders. As teams grew, companies realized the need for dedicated management roles, leading to the promotion of senior engineers to dual roles of tech lead and manager, which worked for small teams but failed at scale. As teams expanded, the complexity of balancing coding with management tasks became apparent, prompting a separation of roles between individual contributors (IC

Liquid Glass is a new design paradigm introduced by Apple that enhances the user experience across its product ecosystem. It merges dynamic and expressive visual elements to create a flexible, organic interface that interacts intuitively with users. This design builds on historical elements from previous Apple interfaces, such as Aqua from Mac OS X and the fluid features introduced in iOS and other technologies. Liquid Glass is characterized as a digital meta-material that manipulates light in a way that mimics the behavior of liquid, responding fluidly to touch

Hexagonal Architecture and Clean Architecture are often regarded as distinct concepts, but they fundamentally represent the same principle: applying the Dependency Inversion Principle to separate business logic from infrastructure elements like databases and UI components. The core idea is to ensure that business logic, which drives profitability, does not directly rely on infrastructure. Two key frameworks illustrate this: Alistair Cockburn's hexagon model, where the application logic is inside the hexagon and everything else is outside, and Uncle Bob's concentric circles
