Image Optimization for the Modern Web
A practical image optimization guide covering dimensions, modern formats, responsive images, loading priority and the mistakes that hurt LCP.
Caching and CDN Strategies for Fast Static Sites
Learn how browser caching, immutable assets, cache-control headers and CDNs work together to make static websites faster and cheaper.
Embeddings Explained: How AI Turns Text into Vectors
A practical explanation of embeddings, similarity, vector dimensions, chunking and how embeddings power search, RAG and recommendations.

07 — The StackSignal loop
Learn → Build → Measure → Ship
A compact workflow for turning one article into a working engineering habit.
01
Learn
Understand the constraint and the failure mode.
02
Build
Copy the pattern into a small test project.
03
Measure
Use real numbers, not intuition, to validate it.
04
Ship
Keep the trade-off that survives production.
