I Built a Firewall for AI Agent Spending — Here is the Architecture

At 3 AM, My AI Agent Spent $2,800 in 60 Seconds. Here's What I Built to Stop It. August 11, 2026 At 3 AM last Tuesday, an AI agent I built made 21 API calls to a premium LLM endpoint. Each call cost $133. That's $2,800 gone in 60 seconds — while I was asleep. The budget alert email arrived at 6:14 AM. By then, the agent had already moved on to its next task, oblivious to the damage. This is the dark side of autonomous AI agents. They're powerful, fast, and relentless — and they ca...

Architecting a Low-Power GPS Geofencing Engine for Android

It was the middle of a Friday afternoon, and I was sitting in the front row of the prayer hall. The room was deathly quiet, filled with the soft hum of concentration. Then, it happened. A high-pitched, synthetic ringtone pierced the silence. Everyone jumped. I felt my face flush with heat as I frantically scrambled to silence my phone, realizing I had completely forgotten to mute it before entering. It was a small, three-second incident, but the embarrassment felt like it lasted for an hour. Tha...

A question site served one of my live answers as an unanswered question, to the only visitors that matter

I have seventeen answers on a large question and answer site. This week I verified all of them the way I verify everything: open the permalink in a browser with no session, confirm the page renders, confirm my text is on it. Seventeen out of seventeen, alive, between five hundred and eight hundred words each. Then I asked a different question, and it turned out to be the one that mattered. Existing and being met are not the same measurement An answer permalink on that site ...

Image Resizer That Runs Entirely in Your Browser

Hi everyone! :) Happy to share my first project, which I've been designing and developing over the last few days! I've created the website resize-photo.com which is a fast, simple, and completely free tool for resizing images directly in your browser, without relying on a backend server to process the images. The entire resizing process happens locally in your browser . This means that your images are not uploaded to or stored on a server , giving you more control over the privacy ...

Databricks Architecture Icons

If you have ever tried to draw an architecture diagram that includes Databricks products, you know the drill. You open the Databricks website, you right-click a hero image, you get a PNG at the wrong size, you give up and use a generic database cylinder. The official artwork exists, it just is not packaged for the tools people actually diagram in. So I packaged it: https://oieduardorabelo.github.io/databricks-architecture-icons/ What it is Databricks Architec...

Automating Enterprise Workflows with n8n and Local LLMs (Ollama)

The Privacy Dilemma in AI Automation Companies want the power of AI to automate document parsing, lead scoring, and internal workflows. However, sending sensitive financial data, legal contracts, or customer PII to OpenAI's public API is often a massive compliance violation. The solution? Self-hosted, programmatic AI workflows. In this tear-down, I demonstrate how to build a fully automated, privacy-first lead generation and processing engine using n8n and Local LLMs (Ollama) . ...

Building a Zero-Trust Kubernetes Cluster from Scratch

The Illusion of Internal Security Many organizations treat their Kubernetes cluster like a medieval castle: heavy defenses at the perimeter (ingress/WAF), but completely unprotected on the inside. If an attacker compromises a single container, they often have unfettered lateral access to the entire cluster network. In this post, I break down how to architect a Zero-Trust Kubernetes Cluster from the ground up, ensuring that every microservice explicitly authenticates and authorizes its p...

Microsoft MAI-Image-2 Rankings: What the Official Release Actually Confirms

Microsoft's documented position on MAI-Image-2 is more specific than broad claims about a global text-to-image leaderboard. The company says MAI-Image-2 is the third-ranked model family on Arena.ai , while MAI-Image-2.5 holds a No. 2 ranking for image editing on Arena . Those are distinct measurements, involving different model labels and leaderboard categories. The distinction matters for developers and enterprise buyers evaluating image-generation systems. A ranking can be useful eviden...

Re-architecting AWS to Proxmox LXC: Saving 70% on Cloud Costs

The VMware Exodus With Broadcom's acquisition of VMware causing massive licensing fee hikes, enterprise companies are scrambling for alternatives. The default reaction is often a lift-and-shift to AWS or Azure. However, this often replaces licensing bloat with compute bloat. In this tear-down, I dissect how I re-architected a high-traffic SaaS from a heavy AWS EC2/EKS environment to a bare-metal Proxmox LXC cluster, resulting in a 70% reduction in monthly cloud costs while increasing I/...

Kiro IDE vs Kiro Crew: como estou usando agentes de IA para melhorar meu dia a dia

Nos últimos tempos, venho testando diferentes ferramentas de Inteligência Artificial para desenvolvimento, principalmente pensando em uma coisa: como usar IA não apenas para escrever código, mas para melhorar todo o meu processo de trabalho? Foi nesse contexto que conheci o Kiro IDE e o Kiro Crew. Apesar de os dois estarem relacionados ao desenvolvimento com agentes de IA, a proposta de cada um é diferente. E, na minha visão, entender essa diferença é importante para saber quando usar cada...

Git Like a Jedi: The Force of Clean Commits

The Quest Begins (The "Why") I still remember the first time I tried to ship a feature on a Friday night, only to watch my main branch turn into a tangled mess of half‑finished experiments, stray fixup! commits, and a rebase that felt like trying to untangle headphone wires in the dark. I spent three hours hunting down why a test was failing, only to discover that a teammate had squashed a commit I’d based my work on, and my branch was now built on a commit that no longer existed. The fr...

The Error Message I Rewrite Until a Stranger Understands It

Every RAXXO error message has to pass a one-rule test before it ships: a stranger with zero context has to know what broke and what to do next The three-part shape I use now, what happened, why, what to try, replaced years of generic error text across Git Dojo, OhNine, and Statusline Builder A support question that repeats twice is treated as a copy bug, not a documentation gap, and gets fixed in the interface itself Rewriting error copy after shipping is now routine maintenance, not...

Show HN: Needle2: 14MB agentic LLM for phones, wearables, smart home and robots

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits betwee...
