Emita credenciais digitais verificáveis com BADGES.ninja: guia em português para devs e plataformas EAD

Se você desenvolve uma plataforma de cursos online, um LMS, um bootcamp ou qualquer produto que entregue "diplomas" ao final de um módulo, provavelmente está gerando hoje um PDF e enviando por email.

Launching a Windows Server on AWS EC2

When people start learning cloud engineering, they often begin with Linux servers and for good reason. But in real-world environments, Windows servers are just as important. From enterprise applications to legacy systems and Active Directory environments, Windows workloads are everywhere. So at some point in your cloud journey, you need to answer this question: Can you confidently deploy and se...

AI saved a company $500k. The test suite did the actual work.

Many people are sharing the story of Reco that saved $500k a year using AI to rewrite a JavaScript JSONata implementation to Go. But most of those people are sharing the wrong lesson. The headline makes it sound like magic. Take some AI, point it at some old code, get new code, save half a mil. But if you actually read what went down, the magic part wasn't the AI. The Part Nobody Wants ...

Type-safe collections in PHP 8.4: what I wish arrays had

You know the feeling. You're three callbacks deep in array_map, you tack on array_filter, then array_values to fix the keys, and PhpStorm gives up and types everything as array. PHPStan was useful five lines ago. Now it's just nodding politely. I spent six months of weekends building a library to fix this. It's called noctud/collection, it's PHP 8.4+ only, and this post is about why. Th...

How I Rebuilt a Three-Layer Cache System in Java — Redis, L1, and MongoDB Done Right

I've been working on Nexus, a backend infrastructure project, and recently hit a point where the data synchronization layer needed a serious rethink. What looked like a working cache system turned out to have a broken hierarchy, silent data loss paths, race conditions, and a latent deadlock waiting to happen. This post walks through every problem I found in the original code and exactly how I fix...

You Can't Build a Palace on a Broken Base ---My honest reaction to Google Cloud NEXT '26 — from a loyalist

This is a submission for the Google Cloud NEXT Writing Challenge The Problem with Gemini The discussion, the demos, the announcements at Google Cloud NEXT '26 were out of this world. I listened. I was genuinely excited. Then I decided to put it to the test. I copied the two keynote transcripts and asked my Gemini Pro how to use the new features. Gemini proudly declared: "I am the platform.

Why LLM Agents Fail: Four Mechanisms of Cognitive Decay and the Reasoning Harness Layer

LLM agents fail in four predictable, mechanism-level ways. Attention decay, reasoning decay, sycophantic collapse, hallucination drift. The current stack (prompting, fine-tuning, RAG, agent loops) cannot close them because each layer operates inside the same decaying chain. The fix is an external layer we call a reasoning harness. If you have built an agent that runs more than ten steps, you have...

Stop Building One Giant Prompt: A Better Way to Design LLM Systems

Most early LLM apps start the same way: “Let’s just put everything into one prompt and let the model handle it.” So we write a prompt that tries to: validate input transform data generate output summarize add reasoning handle edge cases …and somehow do it all in one call. It works—until it doesn’t. The Problem with “God Prompts” As the prompt grows: Instructions start...

Bayes' theorem in machine learning

Bayes' Theorem describes how to update the probability of a hypothesis when new data is obtained. It reverses conditional probability: instead of asking “what is the probability of the data given the hypothesis?”, we ask “what is the probability of the hypothesis given the observed data?” P(A∣B) = P(B∣A)*P(A) / P(B) P(A∣B) = Likelihood × Prior / Marginal likelihood P(A∣B) — posterior ...

I Built an AI That Makes Real Phone Calls — Here's the Architecture

A few weeks ago, I asked my AI agent to call a local Indian restaurant and order chicken biryani for pickup. I gave it my name, my pickup time preference, and one rule: don't make anything up. It dialed the number. It introduced itself as my assistant. It asked for one chicken biryani to-go, confirmed the $15 price, accepted a 20-minute pickup window, said thank you, and hung up. I drove over and...

Software Is Dissolving Into the Model

Two repositories caught my eye this month. The first is google/agents-cli, Google's official tooling for building agents on Google Cloud — a CLI plus a bundle of markdown "skills" that any coding assistant (Claude Code, Codex, Gemini CLI, Cursor) can pick up. The second is Flipbook, an experimental "browser" launched by ex-OpenAI researchers two days ago. Flipbook has no HTML, no DOM, no rendered ...
