SmartKNN vs Weighted_KNN & KNN: A Practical Benchmark on Real Regression Datasets K-Nearest Neighbours is still widely used in industry because it’s simple, interpretable, and surprisingly strong on tabular data.But vanilla KNN falls apart when the real world kicks in — noise, irrelevant features, skewed scales, and mixed data types.**This benchmark compares three variants across…

Hi there — I’m the Observer, a lifelong tinkerer with AI tools, creative workflows, and “what happens when advanced models meet real‑world constraints.” I’ve recently gotten my hands on a fascinating new foundation model and accompanying service, and I wanted to share my experience with the community at DEV Community (because yes, this audience will…

TL;DR: These 7 skills separate DevOps engineers who grow FAST from those stuck troubleshooting for years. Each one looks simple but has hidden layers that only show up in production. Read on for real examples, actionable depth, and exactly what to practice. 1️⃣ Linux Fundamentals ❗ Why it matters Every server, container, Kubernetes node, CI…

API documentation is crucial for any modern application, and for Go APIs Swagger (OpenAPI) has become the industry standard.For Go developers, swaggo provides an elegant solution to generate comprehensive API documentation directly from code annotations. Why Swagger Matters for Go APIs When building REST APIs, documentation often becomes outdated as code evolves. Swagger solves this…

Moving beyond static infrastructure definitions is the next major step in mastering Infrastructure as Code (IaC). While hardcoding values in a single .tf file works for a simple proof of concept, real world cloud environments demand flexibility, reusability, and consistency. This is where Terraform Variables become indispensable.Terraform variables eliminate the need to repeat values across…

You know what’s funny? We keep inventing new ways to do the same thing: make HTML dynamic. React gave us JSX. Vue gave us v-bind. Alpine gave us x-data. Svelte gave us its own template syntax. Each one reinvented how we write HTML, then asked us to install build tools to compile it back into……

We reduced 60 tools to 9. Same functionality. 85% less context overhead. REST conventions work brilliantly for human developers who read documentation once and remember endpoints forever. But your API consumer isn’t human anymore. It’s an LLM with a 200k context window that re-reads every tool description on every turn. And it’s paying per token….

Introduction The data access layer is the foundation of web applications, sitting at the bottom of the layered architectures that power enterprise code. Mitsuki’s data layer, centered around the @CrudRepository decorator, is designed to help you prototype in early stages as well as orchestrate more complex queries down the line, maximizing your time to focus…

Docker isn’t truly native outside Linux, and here’s why. If you’re using Docker on Windows or macOS, your containers aren’t running directly on those operating systems. They run inside a small Linux virtual machine, created by Docker Desktop using technologies like WSL2, Hyper-V, or a hypervisor. Docker was originally built only for Linux because containerization,…
