A 10 second timeout in our safety check silently killed replies for 3 weeks

We run an agent that talks to customers on live channels, and I noticed something uncomfortable after going back through our three worst incidents. The model wasn't the problem. A lot of the damage came from code we had added specifically to make the system safer. One example was a grounding check that runs before a reply is allowed to leave the system. It had a 10 second timeout. That was plenty ...

When I Narrowed My Human Inputs Down to Just Todoist and Discord, the System Started Running Itself

Originally published on my Substack. I'm a Microsoft MVP based in Japan, writing in English about the AI agent systems I actually run in production. AI tools have multiplied. So have agents, skills, and automation scripts. And yet, somehow, my hands are never free. I wake up, open a dashboard, check notifications, go look at the logs for a failed job, and think, "wait, where was that process ...

STAY - Keep the Days You Got

This is a submission for Weekend Challenge: Dog Days Edition What I Built Dogs don't stay long enough. That is the entire idea behind STAY. STAY is an interactive experience about time, attention, and memory. It compresses the life of a dog into a few minutes, lets you experience the small choices that make up that life, and then gives you a way to preserve the moments that mattered....

Private AI Inference with Homomorphic Encryption: A Practical Guide to Computing on Encrypted Data

In 2009, Craig Gentry proved that it is possible to compute on encrypted data without ever decrypting it, and the result was widely treated as a theoretical curiosity. Sixteen years later, homomorphic encryption has crossed from conference papers into production pipelines: banks screen transactions against encrypted watchlists, hospitals run diagnostic models on data that never leaves their custod...

Navigating Floods Without Data: Building Sentinel Voice Agent in 10 Days

It was during the peak monsoon season when I read a distress report from a family stranded on their rooftop. Power was flickering, rain was hammering against the walls, and cellular data was down to a crawling 2G edge. They had a phone with 14% battery, but opening an emergency app or downloading heavy government disaster PDFs was impossible. All they could do was place a direct phone call. Tha...

Prompt engineering that actually works (and what does not)

Prompt engineering has a bad reputation because most of it is superstition. But underneath the "you are a helpful assistant" cargo-culting, there are a handful of techniques that reliably work — and they're grounded in how the model actually behaves. Let me separate the real patterns from the folklore. These are the ones that move quality measurably, not the magic phrases people paste around with...

Most glassmorphism is blur + a white overlay. I extracted the actual refraction into a Claude Code skill

Every glassmorphism snippet I've seen is backdrop-filter: blur() plus a white overlay. That's a blurred rectangle. Real glass bends what's behind it, hardest at the edge — and that part is missing everywhere. Built it for a production Angular app, pulled it out as a Claude Code plugin: https://github.com/stormaref/LiquidGlassSkill /plugin marketplace add stormaref/LiquidGlassSkill /plugin inst...

Qwen 3.8 27B Topped Hacker News in a Day. Here's How to Run It Locally From Spring Boot

Yesterday morning my feed exploded with a model release again. But this one was different from the usual frontier drop. Qwen 3.8 27B hit the top of Hacker News and stayed there: at the time I checked, the thread had passed 1,194 points with 713 comments in under a day. That is the kind of heat normally reserved for a $5-per-million-token API announcement. The twist is that this is a dense 27-bill...

You added an MCP server to your AI assistant. Did you check what it can touch?

You added an MCP server to your AI assistant. Did you check what it can touch? MCP servers give your AI assistant new abilities: read your filesystem, query your database, call an API, run a shell command. That is the whole point of them. It is also the whole point of the risk. The permission question nobody asks When you install a normal browser extension, you at least see ...

This is Level 5 of our Kubernetes networking series. So far, we've built up a solid foundation: LEVEL 1 — Pod networking LEVEL 2 — Pod-to-Pod communication LEVEL 3 — Service (a stable internal endpoint) LEVEL 4 — DNS (service name → Service IP) But we still have a glaring gap: how does a real user on the internet actually reach your Kubernetes application? That's exactly what this article...

My AI Agent Tried to Delete Every Customer Record. Here's What Stopped It.

Last Tuesday, 2:47 AM. I was asleep. My AI coding agent was not. It had been running autonomously for hours, working through a backlog of database optimization tasks on my production infrastructure. Slow query on the profiles table. Agent finds the table, analyzes row counts, decides the data looks stale. DELETE FROM profiles No WHERE clause. Across 24 PostgreSQL databases. Every single custome...

The IR Is a sqlglot AST

Every data tool has an intermediate representation, whether it admits to one or not. It is the thing a model becomes after parsing and before execution, and it quietly decides what the tool can do. dbt's IR is templated text, which is why ref() is a string and why a macro can produce SQL no analyser can reason about. An earlier iteration of Interlace effectively had a pandas DataFrame as its IR —...

Beyond the Demo: Building Production-Ready AI Agents — A Guide to Benchmarking, Cost Optimization, and Tooling in 2026

Originally published on tamiz.pro. Most AI agents ship from a notebook, impress in a demo, and quietly fail in production. The gap isn't intelligence — it's observability, evaluation rigor, and cost discipline. By 2026, the agent engineering field has matured past prompt-chaining tutorials into a genuine discipline with eval frameworks, trace-based debugging, and structured cost controls. This gu...

May the STAR Be With You: Mastering Behavioural Interviews

The Quest Begins (The "Why") I still remember my first behavioural interview like it was yesterday. I walked in, shook hands, and the interviewer hit me with: “Tell me about a time you dealt with a difficult teammate.” My brain froze. I started rambling about a project, threw in a few buzzwords, and ended with a weak “we worked it out.” The interviewer smiled politely, but I could see t...

The formal problem: CWE-367 Time-of-check to time-of-use (TOCTOU) is a formally catalogued class of race condition, CWE-367, first documented in 2006 and still actively relevant two decades later. The pattern: a program evaluates a precondition, then acts on a resource whose state it assumes is unchanged, without any atomicity guarantee between the two operations. The canonical C example: // ...
