If you have spent any time working with Node.js, you have almost certainly hit the infamous “Cannot find module” error. It shows up as Error: Cannot find module ‘some-package’ or Error: Cannot find module ‘./utils’, and it has a way…
Let me settle something right now. If you have been writing Buffer.from() and new ArrayBuffer() interchangeably without understanding why, you are leaving performance on the table and introducing subtle bugs that will surface at 3 AM during a production incident.…
If you have ever wondered why your Node.js application behaves differently on your laptop compared to the server it runs on in production, the answer is almost always the same: NODE_ENV. This single environment variable is one of the most…
Spotting the difference between a mid-level coder and a senior Go engineer usually takes me less than five minutes during a technical interview. True mastery shows up when a candidate starts discussing memory alignment and the inner workings of the…
Hours of my life have been wasted debugging daylight saving time bugs caused by the legacy JavaScript Date object. The new Temporal API finally gives us an immutable, timezone-aware system that actually works for global applications. Temporal introduces distinct data…
Moving away from fragile point-to-point APIs toward a distributed event log was the best architectural decision my team made last year. Kafka provides the durability and scale you need when standard message queues start to buckle under load. Apache Kafka…
Seeing a model process a 2-hour video stream in seconds changed how I think about building AI-driven features. You no longer need to manually stitch together static images now that Gemini 3.1 and GPT-5.4 handle native video input. Integrating these…
Shipping code that performs consistently across slow mobile networks is the biggest challenge I face when building modern React apps. Next.js 16 solves this by moving the heavy lifting back to the server where it belongs. Moving logic to the…
I choose between Claude Code, Aider, and Cursor based on how each tool handles repository context and terminal execution. Professional software engineering in Q2 2026 relies on agentic loops that move beyond simple code completion. Claude Code provides a terminal-native…
If you work with binary data in JavaScript, you have two main options: Node.js Buffers or browser-based ArrayBuffers. The short answer: use Node.js Buffer for server-side file operations, networking, and cryptography. Use ArrayBuffer for cross-platform browser work, WebGL, and universal…
