Day 72 of 100 Days Of Code — Static Files, Media Files, and Environment Variables in Django

Yesterday, the API was fully secured with token authentication. Today, for Day 72, I covered the practical side of Django that nobody talks about much, but every real project needs static files, media files, and environment variables. These aren't glamorous topics, but skipping them means your proje...

Why Build a Local MCP Server (And How to Do It in 15 Minutes)

Model Context Protocol (MCP) servers are changing how AI agents interact with external tools and data sources. In this article, I'll walk through why you might want to build your own local MCP server and how to do it in under 15 minutes. Why Build a Local MCP Server? The default MCP serv...

How Autonomous AI Agents Become Secure by Design With Docker Sandboxes

I've been running AI coding agents for a while now. Claude Code on my MacBook, pointed at a project directory, autonomously editing files, running tests, pushing commits. It's genuinely useful — the kind of useful that makes you wonder how you shipped code without it. But a few months ago I started...

Indirect Prompt Injection: The XSS of the AI Era

Hey Dev.to community! 🛡️ I've been focusing my recent research on the intersection of LLMs and security. While jailbreaking often makes the headlines, there's a more silent and arguably more dangerous threat: Indirect Prompt Injection (IPI). I originally documented this study in the Hermes Codex,...

Application Load Balancer de EKS se desvincula de WAF

La creación de recursos fuera de infraestructura como código suele darnos sorpresas, regularmente muchos dan mantenimiento a su infraestructura a través de cloudformation, sin embargo en algunos servicios es recomendable que se tome en cuenta la documentación oficial para prevenir imprevistos que pu...

From Spreadsheets to Predictive Models: Understanding Two Data Careers That Look Similar but Aren’t

Introduction If you’ve ever explored careers in data, you’ve probably come across the roles of Data Scientist and Data Analyst. At first glance, they seem almost identical—both deal with data, both use similar tools, and both help businesses make better decisions. But once you look deeper, the dif...

I am new to the world of tech, I hope to get the needed support from this community of Developers

What No One Tells You Before You Start Building Multi-Agent Systems (#3 Will Cost You a Week)

You've got the idea. You've got the LLM calls working. You've got an orchestrator that delegates to specialist agents. It's coming together. Then agent A needs to call agent B — and everything stops. Not because the logic is hard. Because suddenly you're staring at a list of infrastructure problem...

How Top Companies Are Shipping AI Agents Today (Apr 15)

The April 2026 AI Breakthrough: What Developers Actually Need to Know This month, something shifted. Three frontier models dropped. New benchmarks got demolished by AI systems matching human expertise. And the quiet part? Agentic AI just became production infrastructure. Here's what's rea...

ETL vs ELT: The Data Pipeline Behind Every Powerful Dashboard

A Brief History on ETL & ELT Processes Data integration has long been a critical challenge for businesses seeking to unify and leverage data from multiple sources across teams and regions. Since the 1960s, when disk storage and early database management systems first enabled data shar...

The 'Freelance Agentics' Era: How AI Agents Are Reshaping Freelance Work

Hey there! If you've been keeping up with the AI space lately, you know we're in the middle of something genuinely historic. What used to be science fiction is becoming production code — and it's happening fast. The Big Shift: Agents Over Assistants For years, we've been building chat...

Edge Computing Explained for Developers: When Cloud Is Too Slow

Cloud computing transformed how applications are built and deployed. It offered scalability, flexibility, and centralized control. But it also introduced a critical limitation: latency. As applications become more real-time and data-intensive, sending every request to a distant cloud server is no lo...

I Ported ComfyUI Desktop to Ubuntu 26.04

Another Desktop App ported to Linux That was not available. I will Keep going until release day or I run out of apps to port. Let me Know what one you would like to see next! The official ComfyUI Desktop app ships for Windows and macOS. I wanted it on Ubuntu 26.04. So I ported it. Not...

Why I stopped putting LLMs in my agent memory retrieval path

Every agent pipeline I've touched in the last eighteen months reinvents memory, and most of them do it badly. Planner decisions never reach the executor. Giant prompts get passed between agents as "context." Tokens burn on stale data. An LLM call sits in the retrieval path, so the same query return...

"My Company Has Azure OpenAI. My AI Coding Tools Had No Idea What to Do With It."

My company's Azure OpenAI deployment has been running for eight months. Enterprise-grade security controls, compliance logging, the whole setup. Every team that needs AI API access routes through it. Every team except the ones using AI coding tools. Claude Code talks Anthropic protocol. Codex CLI...

Building a Low-Cost Download Distribution Station with Cheap Cloud Servers

Building a Low-Cost Download Distribution Station with Cheap Cloud Servers Cloud storage egress traffic is ridiculously expensive, cross-border access is frustratingly slow, and CDN prices are enough to make you think twice... If you're in the distribution business, you know these pains...

Claude API Tool Use: Building Reliable Agentic Workflows in Production

Claude's tool use (function calling) API is what separates toy chatbots from actual agents. I've built production agents with it — here's what reliable tool use looks like when the stakes are real. How tool use works You define tools as JSON schemas. Claude decides when to call them and...

Writing Test Cases for a To-Do List Application

Introduction When I started learning software testing, I chose a To-Do List application for practice because it is simple and easy to understand. It also has basic features that are commonly used in many applications. Application Features A To-Do List application allows users...

Zero JavaScript: CRUD Completo com Blazor WASM e Radzen

Introdução No artigo anterior desta série, analisei se Blazor WebAssembly está pronto para produção corporativa comparando-o com Angular. A conclusão foi nuançada — Blazor WASM é viável para cenários corporativos internos, mas tem trade-offs que precisam ser avaliados caso a caso. Hoje vo...

GPT-5.4-Cyber Is Really a Fight Over Access Control

OpenAI just made its answer to Anthropic's Mythos pretty clear. This is not just a model story. It is an access-control story. OpenAI wants broader, tiered access through Trusted Access for Cyber. Anthropic wants a tighter gate through Project Glasswing. One side is arguing that verified defenders...

Keel: The Leash for Agentic SDLC Management

Most conversations about agentic engineering focus on two things: the model and the harness. The model reasons, writes code, and makes decisions. The harness orchestrates tool calls, manages context, and coordinates multi-step workflows. Together, they're powerful. Together, they're still missing...

Paginação em APIs REST com C# e EF Core: Guia Prático

Introdução Paginar resultados parece simples: adicione .Skip(offset).Take(pageSize) e pronto. Mas quando a tabela tem 10 milhões de registros, o usuário está na página 5.000, o banco é Oracle 11g, ou o cliente exige scroll infinito sem duplicatas — essa simplicidade desaparece rapidamente...
