Before You Add Kafka, Redis, and Elasticsearch: Try One Postgres First

Last month I was building out my own AI agent infrastructure, the side project where I run a few agents that research, draft, and publish content. The agents needed three things beyond the main database: a job queue, a cache for repeated lookups, and search over article text. My instinct, six years of Spring Boot muscle memory, was to reach for the usual stack. RabbitMQ or Redis Streams for the qu...

The silent bug that taught us to never trust an API success response

Three weeks after launching Nventory we had a silent bug. Inventory was updating correctly everywhere. Except one seller's WooCommerce store. Every sync completed successfully. Every log showed green. Every API call returned 200. The seller's stock was quietly wrong for eleven days before anyone noticed. The bug wasn't in the sync layer. It was in the verification step we hadn't built yet. ja...

Zombie Card Attack Can Revive Expired Visa Cards for Contactless Payments

Researchers at the University of Massachusetts Amherst have demonstrated an attack that revives expired Visa contactless credit cards for real in-store purchases by rewriting the expiration date a point-of-sale (POS) terminal reads over near-field communication (NFC), without breaking any of the card's cryptography. The attack, which the researchers named "Zombie Card," requires physical

Should AI-Generated Code Be Labeled in Your Git History? Lessons from the Linux Kernel's 'Assisted-by' Mandate

Originally published on tamiz.pro. When Linus Torvalds and the Linux Kernel maintainers adopted a formal Assisted-by attribution tag for AI-generated code in 2024, it sent ripples through the engineering world. This wasn't a whimsical policy decision — it was a deliberate stance on code provenance, accountability, and the evolving relationship between human developers and AI assistance tools. For...

You've Configured a Reverse Proxy, But Can You Explain Why It Works? (Part 1)

You wrote proxy_pass http://localhost:3000;, checked it in the browser, saw it working, and called it done. But you couldn't actually explain why it works. What's happening between nginx and the app? Where is the request going? You probably couldn't answer that with any confidence. Getting something working and understanding how it works are two different things. This article (Part 1) is about th...

n8n Automation Partners in Finland: What to Look For (2026)

Finland's automation market has grown fast. More companies want to move off Zapier, cut manual busywork, and connect systems like Microsoft 365, SAP, and Visma without hiring a full engineering team. n8n has become the platform of choice for a lot of that work, because it lets you combine visual workflow building with real code when you need it. That growth also means more vendors. If you're eval...

A look at the geolocation HTML element and how it works

A look at the geolocation HTML element and how it works

The <geolocation> HTML element does exactly what you might think it does. It’s a dedicated element that gets the user’s location, either once or continuously. The options are set using HTML attributes instead of JavaScript, but JavaScript is still needed. However, <geolocation> requires fewer lines of JavaScript and also offers superior error and permission handling. In fact, the <g...

A container per job, without a daemon

Some workloads want an image each. A build that needs a specific toolchain, a test that needs a specific database client, a task whose dependencies are described by something other than a human. The instinct is a Dockerfile and a builder. That means a daemon or a rootless equivalent, a build job in the path of every request, a registry filling with near-identical layers, and, the part that turned...

Taking the network away from a Cloud Run job

If you execute other people's code, at some point you have to decide what it is allowed to reach. Mine should reach nothing: no package registry, no pastebin, no callback to a server that tells it the answer. It should see its own filesystem, its own loopback interface, and the end of the world in every other direction. The usual answers are all heavy. Run your own Kubernetes with a deny-all Netw...

Why "Shady AI" is Security's Next Big Governance Problem

In March 2026, an internal AI agent at Meta triggered a “Sev 1” incident after sensitive company and user data was exposed to employees who weren’t authorized to access it.  The incident began when a Meta employee posted a technical question on an internal forum. An engineer used an approved AI agent to analyze it, but the agent posted its response publicly without approval. The employee

CDN Tsunami Attack Abuses HTTP/3 Translation for Up to 350x DoS Amplification

Cybersecurity researchers have disclosed two denial-of-service (DoS) attacks that exploit how major content delivery networks (CDNs) convert client-facing HTTP/3 traffic into HTTP/1.1 requests to the websites they front, amplifying a low-bandwidth request stream by up to 350x against the origin server. The attacks, collectively named "CDN Tsunami," were evaluated against Alibaba, Baidu,
