kubernetes
Kubernetes is powerful, but it’s also complex. This is my journey of trying to build a “simple” Kubernetes stack and the lessons learned along the way.
The Goal I wanted to create a simple, maintainable Kubernetes setup for a small to medium-sized application. The requirements were:
Easy to understand and maintain Cost-effective Scalable when needed Developer-friendly What I Started With Initial Stack Kubernetes: EKS (AWS) Ingress: NGINX Ingress Controller Database: Managed PostgreSQL (RDS) Monitoring: Prometheus + Grafana Logging: ELK Stack CI/CD: GitLab CI The Reality Check Complexity Crept In What started as “simple” quickly became complex:

vue
Vue is introducing support for declarative UI syntax, bringing it closer to mobile development patterns seen in Kotlin and Swift. This new approach moves away from traditional HTML templates, offering a more modern, type-safe way to build user interfaces.
The Evolution Traditional Vue templates use HTML:
<template> <div class="container"> <h1>{{ title }}</h1> <button @click="handleClick">Click me</button> </div> </template> The new declarative syntax is more similar to SwiftUI or Jetpack Compose:
<script setup> import { View, Text, Button } from "vue-declarative"; const title = ref("Hello World"); function handleClick() { console.log("Clicked!"); } </script> <template> <View class="container"> <Text>{{ title }}</Text> <Button onPress="{handleClick}">Click me</Button> </View> </template> Key Benefits 1. Type Safety The declarative syntax provides better TypeScript support:

react
A critical security vulnerability has been discovered in React’s Server-Side Rendering (SSR) Server Action protocol that could lead to Remote Code Execution (RCE) on the server.
The Vulnerability The issue lies in how React handles Server Actions in SSR environments. When improperly configured, the Server Action protocol can allow attackers to execute arbitrary code on the server.
How It Works Server Actions in React allow you to call server-side functions directly from client components:

debugging
Debugging is an essential skill for any developer, but it can be time-consuming. Here are practical strategies that helped me cut my debugging time in half.
1. Use Browser DevTools Effectively Master the Chrome DevTools or Firefox Developer Tools:
Breakpoints: Set breakpoints strategically, not just on errors Network Tab: Monitor API calls and identify slow requests Performance Tab: Profile your application to find bottlenecks Console: Use console.table() for better data visualization 2. Leverage AI-Powered Debugging Tools Modern AI tools can significantly speed up debugging:

webassembly
The question “Will WebAssembly kill JavaScript?” has been circulating in the developer community for years. Let’s explore this topic with a practical perspective.
What is WebAssembly? WebAssembly (WASM) is a binary instruction format for a stack-based virtual machine. It’s designed as a portable compilation target for high-level languages like C, C++, Rust, and Go, enabling deployment on the web for client and server applications.
JavaScript’s Strengths JavaScript has several advantages that make it unlikely to be completely replaced:

django
Django 6.0 was released today, starting another release cycle for the loved and long-lived Python web framework (now 20 years old!). It comes with a mosaic of new features, contributed to by many.
Template Partials The Django Template Language now supports template partials, making it easier to encapsulate and reuse small named fragments within a template file.
Partials are sections of a template marked by the new {% partialdef %} and {% endpartialdef %} tags. They can be reused within the same template or rendered in isolation.

webdev
This summary distills the DEV post “⚡ Vite vs Turbopack — The Present & Future of Frontend Build Tools (2025 Edition)” into key takeaways for teams choosing a tool.
Quick comparison Dev speed: Vite is already blazing (ESM + on-demand transforms). Turbopack pushes incremental builds in Rust—slightly better for very large repos. HMR: Vite is instant/reliable; Turbopack is fast and improving. Ecosystem: Vite is framework-agnostic with a large plugin ecosystem; Turbopack is strongest in Next.js today. Prod builds: Vite uses Rollup; Turbopack still leans on Webpack for prod (transitioning). Future: Vite is experimenting with Rolldown (Rust-based Rollup successor) to close the Rust gap. How Vite works (dev vs prod) Dev: native ESM served directly; deps pre-bundled once with esbuild; code transformed on demand. Prod: Rollup bundles with tree shaking, code splitting, and minification. Turbopack highlights Rust core focused on incremental/parallel builds and heavy caching. Today powers Next.js dev mode; production migration is ongoing. When to choose which Pick Vite for framework-agnostic projects, small–medium apps, or when you want the broadest plugin ecosystem and stable DX. Watch Turbopack for large Next.js/monorepo scenarios that will benefit most from incremental builds as it matures. Tips for Vite performance Use explicit imports; avoid barrel files; warm up frequently used files; keep plugin set lean; prefer native tooling (CSS/esbuild/SWC). Bottom line: In 2025 Vite is the safe, fast default for most teams; Turbopack is promising for big Next.js codebases and will get more interesting as Rust-based production builds land.
