Skip the theory rabbit holes. This is the caching knowledge that shows up in system design interviews, code reviews, and the 2 AM production incidents nobody warned you about.

Introduction Code reviews. For many developers, they are a necessary evil — a box to check in the development process. However, I have come to appreciate them as a powerful tool for elevating code quality, fostering collaboration, and improving team dynamics. Today, I want to share my journey from viewing code reviews as a mundane task to recognizing their critical role in successful projects. L

Building a Translation Pipeline for International Contract Bidding If your company bids on international contracts, you've probably dealt with the translation bottleneck. Technical proposals need precise translation, certified documents have strict formatting requirements, and procurement deadlines don't wait for anyone. After seeing how UK public procurement translation requirements can make or
Implementing Realistic Ragdoll Physics with Three.js and Rapier.js Have you ever wondered how to transition a character from a fluid animation to a limp, realistic heap upon impact? Whether it's for a game-over sequence or a chaotic physics sandbox, ragdoll physics is a staple of immersive 3D experiences. Today, we’re diving into a implementation of Three.js ragdoll physics using the high-perfor
Inside the five-stage pipeline from 1.1.1, there is another fork right after the parser. PostgreSQL classifies every SQL command into one of two camps. One side holds the optimizable queries, the other holds the utility commands. The classification is decided by a single field on the Query node, commandType, and from that point on the two camps travel completely different paths. One goes through t
I was doing a code review for a colleague when I found it. The component had five useEffect hooks. No errors. No warnings in the console. The PM had signed off on it. It had been in production for three months. But there was a subtle bug that only showed up when the user navigated quickly between pages. Data would flash. State would reset. Sometimes the old user's name would appear for a split sec
Last week I had a problem. I'd built an internal documentation site in Trilium Notes — about 30 notes covering product, marketing, and operations stuff. It was for non-technical teammates who needed to answer questions from developers about the platform. The docs were good. Structured, searchable, complete. But reading 30 notes to find one answer is not great UX, especially for someone who's been
