Your Agent Is Dead Between Tasks. I Fixed That.

A month ago, I realized my AI agent was lazy. Not "won't work" lazy — more like "sits there doing nothing between tasks" lazy. I'd send it a job, it'd execute perfectly, then... silence. Waiting. Burning electricity for zero progress. That felt wrong. A system that could be improving itself, should be improving itself. So I built a simple rule: When idle, don't wait. Survive. The "S...

Abstraction vs. Encapsulation — What’s the Difference? (Simplified)

If you are learning Object-Oriented Programming (OOP), you have definitely seen these two words: Abstraction and Encapsulation. They sound similar. They both involve "hiding" things. And that is why almost every beginner gets confused between them. When I started learning OOP, I used to think they were the same thing. But they are not. They have different goals and solve different problems. In ...

What 3 Months of Studying My Own Thinking Taught Me (And Why You Should Care)

Tags: #productivity #career #learning #beginners #devops Let me ask you something honestly. When was the last time you changed your mind — not because someone argued louder, but because the evidence forced you to? When did you last catch yourself thinking, “Wait… I might be wrong here”? If you're being real, it's rare. And that's not your fault. Your brain wasn’t designed for truth — it was ...

Introducing Xata OSS: Postgres platform with branching, now Apache 2.0

Xata is a cloud-native Postgres platform with the following highlights: Fast branching using Copy-on-Write at the storage level. You can “copy” TB of data in a matter of seconds. Except they are lightweight copies that happen instantly and take very little extra disk space. Scale-to-zero functionality, so inactive databases don’t cost you compute. Together with the previous point, this makes P...

Abstraction in JavaScript — Explained in Simple Words (and How It Differs from Encapsulation)

If you are learning Object-Oriented Programming (OOP) in JavaScript, one word that can feel scary is: Abstraction. When I started learning it, I thought it was some complex math or high-level theory. But I was wrong. The idea is actually very simple. In this post, let’s understand abstraction in very simple words, step by step, using JavaScript. 🧱 What is Abstraction? In simple wo...

I built a zero-dependency React Native animation library — 14 drop-in components, native driver only.

I got tired of adding Reanimated to every project just to fade in a card. So I built react-native-animation-kit — 14 premium animation components for React Native. Zero dependencies. Every animation runs on the native UI thread. Drop in and go.Works on both Android and iOS out of the box. No platform-specific code, no conditional imports, no native modules. One install covers everything. ...

When one translation isn't enough: building konid for real language

I was drafting a work email in French last year — intermediate level, good enough to get through tasks, not good enough to know when I sounded stiff. Google Translate gave me one sentence. No indication of whether it was formal, casual, or somewhere in between. I sent it, got a reply that matched my register exactly, and realized I'd accidentally set the tone for the whole relationship as "overly ...

I was tired of re-explaining my project to Claude every session

I'd start a new Claude Code session and spend the first ten minutes pasting files. "Here's the API gateway. Here's the user service. The gateway talks to users over HTTP. Users publish to this Kafka topic. The payments service consumes it. The shared types live in this package. Here's the schema." Next day. New session. Same ten minutes. Some days I'd realize halfway through that I'd already ...

Why I spent 14 months building a firewall for AI agents

System prompts aren't enough. They are just a polite request for an agent to behave. In production, 'please don't delete the database' is not a security strategy. Today, we are moving SupraWall to a public repository. It's the missing layer for agentic workflows: A hard gate that intercepts every tool call, evaluates it against real-time policy, and injects vault credentials just-in-time. This i...

"Almost every time" vs "every time": why hooks beat instructions for AI agents

The rule your agent keeps ignoring You write "always run tests before committing" in your CLAUDE.md. Your agent follows it. Mostly. On the third run, it skips the tests. On the fifth run, it runs the wrong test suite. By the eighth run, you find a commit with zero test coverage and a cheerful "all checks passed" in the summary. You add the instruction again, in bold this time. Maybe ca...

I benchmarked my compiled language against Node.js, Go, and Python. 1.34 million requests per second is not a typo.

I benchmarked my compiled language against Node.js, Go, and Python. 1.34 million requests per second is not a typo.

Last week, I published an article about building Doolang, a compiled language I made specifically to eliminate API boilerplate. At the end, I dropped a number: 1.34M RPS. I got the same question in at least a dozen DMs: "Okay but where's the actual proof?" Fair point. Throwing out a benchmark number in a sentence and moving on is exactly the kind of thing that deserves skepticism. So I set up a ...
