Choosing between Docker and Kubernetes for production environments significantly impacts security, operational overhead, and cost. This framework provides a security-first approach to help teams decide which container orchestration platform best fits their scale, team capabilities, and compliance needs, emphasizing the importance of proper controls and lifecycle management.

Creating a custom Visual Studio Code theme might seem daunting, but this guide demonstrates how to build one efficiently, from initial color choices with Shiki to granular control with TextMate tokens, leveraging AI assistance and effective debugging techniques.

This article explores methods for approximating the functionality of the proposed CSS `contrast-color()` function, which dynamically adjusts text color (light or dark) based on a background color for optimal accessibility. While `contrast-color()` has limited browser support, modern CSS features like color spaces and `oklch()` can be leveraged to create cross-browser compatible solutions. The piece details approaches based on WCAG 2.2 luminance calculations and a simplified method using perceptual lightness from `oklch()`, highlighting the trade-offs and potential for customizability.

Agentic AI is transforming technology by enabling systems to plan, execute, and persist in tasks autonomously, moving beyond simple generative AI. This shift necessitates a user-centric design approach focused on trust, consent, and accountability. This article explores the distinct research methodologies required to develop effective agentic AI, including mental model interviews, agent journey mapping, and simulated misbehavior testing, alongside key metrics and ethical considerations for building transparent and trustworthy systems.

A discussion on the ongoing debate in JavaScript development regarding the use of let versus const for variable declarations. This article explores common arguments for and against preferring const wherever possible, concluding with a pragmatic approach to the choice.

Grasping the Fetch API can be challenging, especially for those new to JavaScript’s asynchronous operations. This article explores three core concepts—synchronous vs. asynchronous code, callback functions, and Promises—essential for understanding how the Fetch API effectively handles network requests.

React function components and class components differ fundamentally in their mental model, particularly how they handle rendered values. While Hooks have bridged the feature gap, function components inherently capture the props and state from the specific render they belong to, preventing common bugs related to mutable ‘this’ in classes. This article explores this core difference, demonstrating how closures in functions ensure consistency and how refs can be used to access the latest values when necessary.

This article details the implementation of the Strategy design pattern for managing various payment methods in an e-commerce checkout system. It addresses the challenge of building an extensible backend that supports diverse payment options without complex conditional logic, highlighting key features like type safety and easy extensibility.

This post provides an update on recent personal and professional developments. After leaving Meta in July 2023 and spending nearly two years at Bluesky, the author took a much-needed break. Currently in a transitional phase, the author is now offering consulting services focused on UI engineering, particularly React and React Native, to help teams with architectural and performance challenges.

A tool called ReliCSS helps identify outdated CSS in a codebase, offering modern solutions for common legacy issues. It categorizes these “relics” by severity, from high-risk fossils to low-severity vendor prefixes.
