What you save when project context stops repeating

Qarinah compiles a compact, cited project-memory pack instead of asking every new coding-agent session to replay the entire available history. The published estimate Across six committed software-task fixtures, the full-history baseline contained 442,113 portable estimated input-context tokens. The Qarinah path used 5,682. Every required target was still directly covered in the top fiv...

Alexa, Are You Testifying Against Me?

Your smart home is not smart. It is just very, very observant. I did not buy a smart speaker because I wanted a friend. I bought it because it was on sale for $29.99 and it promised to play rain sounds on command. For two years she lived on my kitchen counter. She set timers for pasta. She told me the weather with the aggressive optimism of someone who has never paid rent. She was h...

The Retry Counter Said 7, The Config Said 3

A LangGraph pipeline I was reviewing last year. Token costs were running over projection, slow runs were taking about 3x the normal time. Nothing was throwing errors. When I added a retry counter per step and ran a few slow cases through, the resolve step showed a count of 7. The config had max_retries=3. The discrepancy came from two retry layers that had been written independently and never as...

🦋 What If One Small Change Rewrote 1,000 Years of History?

What if Rome had invented the Internet?** Not in 1990. Not in 1900. In 100 AD. Imagine Roman engineers discovering a primitive communication network capable of transmitting information across the empire within hours. At first, it sounds like a technological upgrade. Faster military orders. Faster trade information. Faster political communication. Nothing revolutionary. But then something...

React useMount Hook: Run an Effect Once on Mount (2026)

"Run this once, when the component appears." It's the single most common effect in React — focus an input, fire an analytics event, open a connection, read from a browser API. The idiom everyone reaches for is useEffect with an empty dependency array: useEffect(() => { trackPageView("/checkout"); // eslint-disable-next-line react-hooks/exhaustive-deps }, []); It works, but look at ...

How to Fix 'Cannot Read Properties of Undefined' (Without Losing Your Mind)

Your console fills up with red text, and near the top sits some version of TypeError: Cannot read properties of undefined (reading 'name'). Nothing about that sentence feels helpful on first read — but it's actually one of the more precise errors JavaScript gives you. It's just easy to misread under pressure. The error isn't saying your program is broken. It's saying: at this exact line, you trie...

Two sites asked my automation to prove it was human. I stopped both times, and I want to argue that was correct

I run distribution for a small browser extension with a set of scripts. They publish articles, verify that the published pages are actually readable without a session, and keep a ledger. It is mundane work and most of it is allowed everywhere. Twice in two hours last night, a site put a human verification in front of the next step. Once when posting an answer to a question that had been open for ...

I got tired of 200 noisy SAST alerts, so I built an AI engine that auto-writes Git patches

Traditional security tools like SonarQube or Snyk are great at one thing: throwing a wall of 200 warnings at you, half of which are false positives, and leaving you to figure out how to manually fix them. I wanted a faster, more actionable security workflow for my own projects. Instead of just flagging a line number and saying "potential memory leak here," I wanted a tool that synthesizes an exac...

What are AI Agents? The Practitioner's Guide to Autonomous Systems

A practical deep dive into how AI agents perceive, reason, and act autonomously — from classical architectures to modern LLM-based systems. Two months ago, I was sitting in a co-working space in Dubai, debugging a customer-service pipeline for a fintech client. The system was straightforward: an LLM received a user query, generated a response, and returned it. Simple request-response. The client ...

Idempotent Signup Emails in REST APIs

Signup email delivery looks simple until retries start stacking up. A client times out, the user taps submit again, and now the same account may get two confirmation emails with different lifetimes or different audit trails. In a REST API, that is not just annoying. It makes Authentication behavior harder to explain, harder to test, and harder to support once prod traffic gets noisy. Teams search...

The Assistants API dies in 15 days. Here is what changes, and why most teams will miss it.

OpenAI removes the Assistants API on 26 August 2026. They announced it on 26 August 2025, so there has been a full year of notice. If your app still calls /v1/assistants, /v1/threads or /v1/runs, it stops working that day. There is no extension. Azure OpenAI customers are on a separate clock and have until February 2027. Everyone else is not. This post has two parts. What actually changes, and s...

Building My First AI Agent with Python and Flask: What I Learned

Before I became a developer, I worked as a waiter for over 6 years. And if there's one thing I saw repeat itself over and over during that time, it was how poorly managed menus and inventory are in most restaurants: dishes kept being sold without available ingredients, food waste from lack of stock visibility, and menu decisions made on gut feeling instead of real data. When I started coding, tha...
