How MCP Turns Your Messy Agents Into Governed Systems

Imagine hiring a contractor and giving them your house keys, your credit card, and zero instructions. No scope of work. No limits on spending. No list of what they're allowed to touch. That's what most agents do with their tools. In post 1, we looked at how AI agents fail. In post 2, we fixed the knowledge problem with Agentic RAG. But there's another class of failure we haven't addressed yet: w...

dvh doesn't solve the mobile keyboard problem. I spent way too much time figuring out why, so I made a 0.8KB hook.

We've all been there — you're building a mobile chat UI or a bottom-anchored menu, the keyboard opens, and your input bar just disappears. You think, "I'll just use dvh, that's what it's for." Nope. By design, dvh only responds to browser UI elements like the URL bar. The virtual keyboard is intentionally treated as an overlay by browsers, so dvh, svh, and 100vh all stay the same value w...

OpenAI Structured Outputs vs Zod: which to use for LLM response validation in 2026

Two approaches to the same problem: making sure an LLM returns valid, typed JSON. One is baked into the API. The other is a validation library you apply after the fact. Here's when to use which. The problem You ask an LLM to return JSON. Sometimes you get valid JSON. Sometimes you get JSON wrapped in markdown. Sometimes you get a friendly explanation instead of JSON. Sometimes you get ...

I Reviewed 47 AI Tools and Here's What Nobody Tells You About This Space

This article was originally published on Medium. I'm cross-posting here for the Dev.to community. I spent the last few months doing something slightly obsessive. I signed up for every major AI tool I could find — writing tools, image generators, code editors, video makers, chatbots — and used each one for at least 20 minutes before writing a single word about it. Not skimming the features p...

I started focusing on the cost of distractions more so I built this app

I always thought my problem was lack of discipline. Like I just needed to “focus more”. But recently I tried something simple: I started tracking when I get distracted during work. Not big breaks, just small things: opening instagram on my pc for a few seconds, checking something quickly, switching tabs. And what surprised me wasn’t the distractions themselves. It was how much time I was losing AF...

I have noticed one interesting thing - the level of understanding of what's really going on, what is the nature of this kind of exploit and how to reliably protect yourself from future ones, is lower than it should be. Therefore, I decided to ...

Is Your Website Invisible to AI? Stop Optimizing for Google, Start Optimizing for ChatGPT

67% of users now get their first answer from an AI assistant rather than clicking a search result. Your site might rank #1 on Google and still be invisible to ChatGPT, Perplexity, and Google AI Overview. The problem: SEO optimizes for ranking algorithms. AI engines don't rank -- they cite. If your content can't be extracted and quoted, it doesn't exist. This is AEO (Answer Engine Optimization), ...

What Happens to Code Quality When You Double the Engineering Team in Twelve Months

The quality degradation pattern that follows rapid hiring — and the practices that prevent it. Doubling an engineering team in twelve months is, by most measures, a success. It means the product is working, the business is growing, and the organisation has the resources to invest in the engineering capacity required to sustain that growth. It is also one of the most reliable predictors of a s...

Why O(n^2) Algorithms Don’t Run the Same: A Practical Sorting Benchmark in C

Introduction Have you ever wondered why algorithms with the same time complexity behave differently in practice? While learning sorting algorithms, I noticed something interesting: Algorithms with the same time complexity can perform very differently in practice. Instead of only relying on theoretical analysis, I decided to build a small benchmark in C to compare the runtime performa...
