8 effective debugging strategies to find and fix bugs like a pro
The article argues that debugging skill is central to trusted software work and lists eight practical tactics: reproduce the bug, narrow it down, use tools, and take breaks when needed.
7 practical tips on performance optimizations in React applications
The post argues that React performance work should start with the biggest bottlenecks, then reduce initial load, rerenders, bundle size, and inefficient business logic.
10 ways to better organize and design your React Application
The page argues that React code organization affects findability, maintenance, and growth. It recommends domain-based folders, absolute paths, shared common modules, wrappers for third-party code, local code placement, and pinned dependencies.
4 tools to supercharge your Jest Testing and increase your productivity while testing
The page recommends four Jest additions to speed up feedback, narrow test runs, improve assertions, and keep console output clean during development.
Why API-First Matters in an AI-Driven World

3 software development principles I wish I knew earlier in my career
The article presents YAGNI, KISS, and DRY as practical principles that shape how software is written and shipped, helping code stay focused, readable, and easier to maintain.
Habits To Start Now To Become a Healthy Senior Coder
Kate Gregory’s talk argues that aging well is a learned skill built from exercise, preventive care, friendship, money, and adjusting expectations about loss, work, and age.
15 React Component Principles & Best Practices for Better Software Architecture & Design
The article lists 15 React component practices aimed at cleaner, more maintainable apps: favor function components, named components, smaller components, fewer props, hooks, custom hooks, error boundaries, and Suspense.
Devs: Don’t Just Read About Design Patterns, Implement Them
The post argues that design patterns are more useful as examples you build than as theory you read. A contrived C# animal-mission setup shows how decoupling lets missions, heroes, and lairs vary independently.
Angular’s Efforts To Be Easier and Developer Friendly
Angular says it is now simpler and more developer-friendly, with clearer template syntax, Signals, finer-grained lazy loading, partial hydration, and AI features such as structured output with Gemini.
Mentat will apply for jobs on your behalf and guarantee you get an interview
Mentat, from Y Combinator’s Summer 2016 batch, helps job seekers by optimizing LinkedIn and resumes, writing cover letters, and applying to jobs by hand, with a money-back interview guarantee.
Secrets of "Clear Thinking"
The post argues that decisions and outcomes are separate, then outlines habits from Shane Parrish’s book for clearer thinking: notice defaults, define problems, compare options, gather better information, and document choices.
You'll never be ready for anything that matters
The author says he made major life changes while unprepared, including sobriety, fatherhood, a startup, and a long charity bike ride, and argues that readiness never comes first.
CQRS Pattern With MediatR
CQRS separates writes from reads so each side can be optimized independently. The text also shows how MediatR can model commands and queries with handlers and a request pipeline.
API Versioning in ASP.NET Core
The page explains how API versioning lets ASP.NET Core APIs evolve without breaking existing clients, and shows how to add it with Asp.Versioning, choose version readers, and manage controllers and Minimal APIs.
The Secret to Growth as Software Engineer
