1 INTRODUÇÃO No cenário atual do desenvolvimento de software, a integração entre sistemas heterogêneos deixou de ser uma exceção e virou regra. Com a popularização das aplicações em rede, os Web Services se tornaram a espinha dorsal dessa comunicação. Dentre as várias abordagens arquiteturais que estudamos no curso, o Representational State Transfer (REST) acabou se consolidando como o verdadeiro padrão de mercado para a construção de APIs. Um erro comum — e que muitas vezes confunde quem está c

I’ve spent the last nine months deep in the weeds of Rust, distributed systems, and FIPS-standardized cryptography. The result is Dytallix : the first solo-built, PQC-native Layer 1 blockchain. There is no ECDSA here. No hybrid mode. No legacy accounts. Dytallix was built from the ground up with a "zero legacy mandate," meaning every address, every signature, and every handshake is quantum-secure from inception. Why PQC-Native? Adversaries are currently capturing encrypted traffic to decrypt it

If you've never shipped an Android app to Google Play before, the signing key part is where a lot of people get quietly stuck. It's not a hard concept, but the way Google documents it makes it feel like you're juggling three different keys that could all brick your release if you mess up. Here's what actually went wrong for me the first time. What I thought I was doing I generated a keystore the way most tutorials tell you. Ran keytool, set a password, saved the .jks file somewhere on my machine

Introduction: The Practical Graph This post will show a practical, hands-on example that implements a serverless topology using the tc (Topology Composer) framework. It supports synchronous entry points with asynchronous real-time updates. You will construct a REST API (API Gateway Routes) backed by a Lambda producer. This Lambda producer emits an event to a an EventBridge Bus, which the framework routes to an AppSync Channel for Websocket broadcast via a secondary notifier function. Finally wil

So with the new Visual Studio edition, there is a template available for an ASP .NET MVC application with Vue JS. The template does most of the work for you, it's pretty cool. But what if you want to migrate an existing, production running MVC application slowly to Vue JS 3? Not so straight-forward, right? It took me some time to get it right. Hopefully I can save you some time! Needed Software: .NET - any version really, Node JS >= v24.11.0, Any IDE for ease Create the MVC application So we wil

Claude Code can edit files, run shell commands, and write tests — but it cannot fetch live web pages on its own. Connect it to CrawlForge MCP and it gains 20 scraping tools that run straight from your terminal. npm install -g crawlforge-mcp-server npx crawlforge-setup # paste your API key # Now in Claude Code: # > Fetch https://news.ycombinator.com and list the top 5 stories This guide shows you how to scrape websites with Claude Code using CrawlForge MCP, from installation to stealth-mode bypas

Code review is better when you can see the changes running live. Reading a diff in GitHub, GitLab, or Bitbucket tells you what changed, but clicking through a live preview tells you whether it actually works. Preview environments give every pull request its own temporary deployment, complete with a unique URL, a fresh database, and the full application stack. Reviewers can test features, designers can verify UI changes, and product managers can sign off on behavior without ever pulling code loca

After running 35+ AI agents in production for months, I have learned that reliability is not about preventing failures—it is about containing them. Here is the infrastructure layer most people skip. The Problem Most AI agents are built for demos. They work beautifully in controlled environments. Then they hit production and everything falls apart. Your model goes down. Your agent hangs. Your memory expires. And suddenly that "autonomous" system needs a human to manually restart it. I learned thi

Vulnerability and malware are the topics that dominate our review for this week. It's not good news that we will mostly talk about two topics. Mind you, these two, in the wrong hands, can wreak havoc on users around the world. Do you remember WannaCry? Let's begin our review. Someone planted backdoors in dozens of WordPress plug-ins used in thousands of websites You might think: I don't use WordPress, why should I care? Well, you should care because you never know where you'll find yourself in t

Introducción: un espacio que destapó una grieta en Discord En octubre de 2022, un investigador con el alias tmctmt tecleó por accidente un espacio dentro de un enlace de adjunto en Discord y, en vez de ver la imagen, recibió un 502 Bad Gateway . Ese tropiezo, tan trivial como apretar una tecla de más, destapó una de las vulnerabilidades más elegantes e inquietantes reportadas en los últimos años: un HTTP desync en el proxy de medios de media.discordapp.net que permitía leer en tiempo real los ar

Now that we have familiarized ourselves with the default minikube start command, let's dive deeper into Minikube to understand some of its more advanced features. The minikube start by default selects a driver isolation software, such as a hypervisor or a container runtime, if one (VitualBox) or multiple are installed on the host workstation . In addition it downloads the latest Kubernetes version components. With the selected driver software it provisions a single VM named minikube (with hardwa

The French role-playing game is crowned at another ceremony - but takes just a handful of awards home.

My homelab runs the usual stack — Sonarr, Radarr, Prowlarr, qBittorrent, Plex. I was getting ntfy alerts at all hours for things like ffprobe metadata reads and HTTP 429s from indexers. Not actionable, just noise. So I built Cortex : a monitoring layer that sends Docker logs through a local LLM (Ollama) every 30 minutes, filters the noise, and routes only meaningful alerts to my phone. The problem with threshold-based monitoring Standard monitoring tools watch numbers. CPU > 80%? Alert. Disk > 9

How I Built a Production AI Agent for $5/month Using Open Source + OpenRouter Stop overpaying for AI APIs — here's what serious builders do instead. I spent three months running an AI agent on Claude 3.5 Sonnet through OpenAI's API. The monthly bill hit $847. Then I rebuilt it using open-source components and OpenRouter. Same performance. $5.23/month. This isn't a theoretical exercise. This agent handles customer support triage, generates summaries, and routes inquiries across three different se
