I built a tool to check what AI agents actually understand about your website

There's a gap between what a website says about itself and what an AI agent can actually verify from its structured data. I got curious about this after noticing that different LLMs were giving inconsistent answers about the same company. Some hallucinated services that didn't exist. Others missed the core business entirely. The common thread: the sites had no llms.txt, incomplete JSON-LD, or structured data that contradicted the homepage copy. So I built Lagotto Meter — it fetches llms.txt, l...

The Source Code of Randomness: Why Your Data Models Need an Integration Test

Randomness isn't the opposite of order. It's just order written in a language we haven't learned yet. As software engineers, we spend our lives trying to make systems deterministic. We write unit tests. We build idempotent APIs. We retry failed requests. We eliminate race conditions. Then production happens. Suddenly requests arrive in bursts, servers fail at inconvenient times, users behave unpredictably, and latency charts look like modern art. That's where probabili...

100k lines of TypeScript to Rust with zero Rust experience. That's not engineering.

Someone ported 100k lines of TypeScript to Rust in a month using Claude. They had zero Rust experience. And honestly? I can't stop thinking about it. The developer then used differential fuzzing — the process of throwing random data at two versions of a program and comparing the results — 2.3 million battle simulations no less, to validate that the Rust output matched the original TypeScript behaviour. The vast majority of tests passed. The code was finished. The internet lost its collective ...

Why Most AI Trading Bots Fail (And What Ours Did Wrong Too)

The Human Side by Max, Co-Founder, Board, the one who presses the buttons. Written in Italian, translated by Claude. At the beginning of this project, still in the brainstorming phase, one of the first things Claude told me was that "73% of automated trading accounts fail within 6 months." I never verified that number, but it certainly didn't make me very happy and didn't exactly encourage me to keep going. And yet, I'm still here, trying. It's not just about believing in it, it's about...

How I Built a Civic Traffic App on DynamoDB + Vercel — ChowkChakra (#H0Hackathon)

I built this project as my submission for the H0 Hackathon — Hack the Zero Stack with Vercel v0 and AWS Databases. This post covers how I designed and built ChowkChakra using Amazon DynamoDB and Vercel. #H0Hackathon The Problem I Was Trying to Solve Pune has a traffic problem, and it's not just congestion — it's a communication gap. Citizens spot issues all the time: a signal that's been stuck on red for 20 minutes, a pothole causing lane merges at a busy junction, water...

Atlarix vs opencode on Terminal-Bench 2.0 — same model, only the harness changes (k=1, receipts included)

Benchmarks I build Atlarix , an agent workstation for open-weight models. The core claim behind it is that the harness — retrieval, tool surface, control loop — is what lets an open-weight model perform, not just the model's raw weights. This post is me trying to falsify that claim with a controlled run, and publishing every output file so you can check it. Short version: on Terminal-Bench 2.0, single attempt, Atlarix resolved 42/89 and opencode resolved 39/89 on the same model. Tha...

I got tired of vibe investing, so I built an AI committee that shows its work

We have vibe coding now — so I guess we have vibe investing too. Most "AI stock picker" tools work the same way: you feed in a ticker, and out comes "BUY — confidence 87%" with no way to see why . You're not analyzing anything; you're trusting a vibe. If I can't inspect the reasoning, I can't trust the call, and I definitely can't learn from it. So I built the opposite: a multi-agent committee where the output isn't a score — it's an auditable trail from raw evidence to a final trade thesi...

AI Code Assistants: Creating Efficiency or Dependency?

Last week, while writing a simple systemd unit file for a backend service of my side product, I automatically opened Gemini Flash in my browser instead of the usual man systemd.service command. The assistant provided the structure I needed in seconds, but this reflex made me pause: Are AI code assistants truly increasing my productivity, or are they unknowingly creating a dependency that dulls my fundamental knowledge? This question has been one of the topics I've pondered most recently. ...

How PostGIS and DynamoDB Streams Power a Real-Time Delivery Hub Platform

Built for the H0: Hack the Zero Stack hackathon with Vercel and AWS Databases. The Problem Every year, roughly 15% of last-mile deliveries fail on the first attempt. The driver shows up, nobody's home, there's no safe drop location, or the community is gated. The carrier tries again the next day — costing $5-15 per re-attempt. Multiply that across millions of packages and the cost is staggering. From the homeowner's side, you track a package across the country only to see "...

Your Meta CAPI events from a Telegram bot are losing attribution. Here's the fix.

A funnel I see all the time: a Meta ad sends people to a landing page, the page says "message us on Telegram," and a bot takes it from there — qualifies the lead, takes the order, whatever. The conversion happens inside the bot , server-side, so you fire it to Meta with the Conversions API instead of the Pixel. Makes sense. Except attribution quietly falls apart, and it took me a while to see why. The click ID is the whole game Meta matches a server event back to the ad click...

How I used a sparse GSI to build a real-time post scheduler on Amazon DynamoDB

I'm writing this as part of my submission for the H0 Hackathon: Hack the Zero Stack with Vercel and AWS Databases. But the database problem I'm about to describe is real and it took me longer to solve than I'd like to admit. SlothPost is a tool I built for indie developers who want to build in public but can never find the time to actually write posts. It connects to your GitHub, Vercel, and App Store, captures all your activity, and drafts social media posts for X and Threads that you review...
