Why Your Web Scrapers Keep Breaking (And How to Build Self-Healing TypeScript Agents Using LLMs and Playwright)

If you have ever maintained a production web scraping pipeline or an automated form-filling assistant, you know the sinking feeling of checking your logs on a Monday morning and seeing a wall of red. A front-end engineer changed a class attribute from btn-primary to btn-action-primary, an A/B testing framework altered the DOM tree hierarchy, or a minor React component update randomized your CSS se...

Starting My Journey into C# and .NET

I've decided to begin my journey: becoming a software engineer, working with C# and the .NET ecosystem. This post is less a tutorial and more a marker in the ground so I have something to look back on later. Why C# and .NET I want to build backend systems that are reliable and scalable, and .NET keeps coming up as a solid, well-supported way to do that. Where I am right now ...

The 8 Performance Fixes That Finally Got My Astro Site to 100 on Mobile PageSpeed

Still trying to hit that elusive 100 on PageSpeed Insights? I was too. I spent far longer than I'd like to admit stuck in the high 80s and low 90s on a real client project. I tried everything the internet recommends—compressing images, minifying JavaScript, lazy loading, removing unused CSS—and yet the score barely moved. Mobile was the real challenge. That's where Lighthouse seems determined t...

What it took to ship a production remote MCP server with OAuth 2.1

Publishing an MCP endpoint is easy. Making it behave consistently across clients is where the work starts. We recently shipped a hosted MCP server for Minds, an evidence-grounded synthetic market research platform. The server now connects to ChatGPT, Claude, Cursor, Google Antigravity, and clients that support Streamable HTTP. Here are the implementation lessons that mattered. 1. The t...

⚡ Why Integer no longer stores its value as a String

If you've used the experimental Integer type from Kotools Types before 5.2.0, you may have noticed arithmetic getting slower as numbers grew larger. That wasn't your imagination — it came from how Integer stored its value internally. 🐛 The problem Every Integer operation — +, -, *, comparisons, even toString() — had to work with a String representation of the number. That means every s...

I Built an App That Works Without Internet — Here's Why Silicon Valley Won't

Most apps assume you're always online. But 3.4 billion people have unreliable or no internet access. I'm a full stack developer based in the Dominican Republic. One of my clients is a cacao aggregator — their vendors drive into the mountains every morning to buy raw cacao from small farmers. No cell signal. No Wi-Fi. No cloud. But they still need to record every purchase, print a receipt, and hav...

How Do SQL Database Engines Work?

Introduction Imagine you own a giant library. Not a small bookshelf — a warehouse with millions of books. Someone walks up to the front desk and asks: "Bring me the three highest-rated cookbooks published after 2015, sorted by rating." You could walk every aisle, open every book, and check each one. That would take days. Instead, a good librarian uses a catalog, knows exactly which ...

Why RAG Docs Chatbots Answer Wrong: Embeddings, Chunking, and Context Fixes

A RAG ask-your-docs chatbot stops hallucinating wrong answers when retrieval is treated as an evaluated evidence pipeline, not a clever prompt. I build ask-your-docs features in Python, and I start with a blunt rule: retrieve evidence, fit it into the prompt budget, and let the model say "not found" when the evidence is absent. Embeddings and chunking are necessary, but they don't prove that the ...

React Mastery Series – Day 16: State Management in React – Understanding Context API

Welcome back to the React Mastery Series! In the previous article, we explored React.memo and useCallback, and learned how they help optimize React applications by reducing unnecessary re-renders. As applications grow, another challenge begins to appear—not performance, but state sharing.

I counted the sources in 13 of Google's AI answers. 168 citations, and not one domain appeared twice.

I keep a daily probe that asks the assistants the buying questions in my category and records every source behind every answer. Last week I pointed it at Google's two AI surfaces, the AI Overview box and the fuller AI Mode, and counted. Thirteen answers. 168 citations. Every single answer used a different domain for each of its sources. Not one domain was cited twice, in any answer, the whole wee...

Building a Secure MCP Server for AI-Assisted VPS Operations Without Giving the AI a Shell

Over the last few months, I have been thinking about a simple but uncomfortable question: If AI tools are becoming part of our engineering workflow, how much access should we actually give them? It is tempting to connect an AI assistant directly to a server and say, "Check what is wrong with production." But if the way you do that is by exposing a raw shell, you have effectively created a rem...

Every Generation Thinks the Next One Has It Easy 💃💃 💃

Is It Wrong to Watch Movies, Cartoons, or Sci-Fi? 🤔 Of course not. We enjoy movies even though they're fictional. We appreciate cartoons even though the characters aren't real. We watch science fiction knowing today's imagination often becomes tomorrow's technology. That made me think about another question: Why is AI-assisted development treated so differently? I'm fond of readin...
