Vera Rubin: NVIDIA’s Blueprint for the Agentic AI Era
If AI keeps getting smarter, can the infrastructure behind it keep up? Artificial intelligence is rapidly moving beyond simply generating answers. Modern AI systems are becoming capable of reasoning through problems, using external tools, retrieving information, executing tasks, and deciding what to do next. This is the idea behind [...]
Multi-Agent AI Isn’t What You Think: Here’s What’s Really Happening Under the Hood
Multi-Agent AI Isn’t What You Think: Here’s What’s Really Happening Under the Hood What if I told you that a “team of AI agents” can sometimes be the same language model being called multiple times with different instructions? No digital employees sitting inside a virtual office. No group of [...]

It helps determine whether a ticket can receive an AI-generated response or requires human review. Support teams often receive a mix of billing concerns, technical issues, account-access problems, product questions, [...]
Meet QUERY: The New HTTP Method for Complex Queries
HTTP has been around for decades, and most developers are already familiar with methods like GET, POST, PUT, and DELETE. These methods are the building blocks behind many of the websites, applications, and APIs we use every day. For simple tasks, they work remarkably well. But as modern applications [...]

Cursor Automations, MCP, and API Integrations: How AI-Powered Workflows Are Reshaping Modern Development
In late 2025, most developers were still using AI coding assistants as glorified autocomplete engines: press Tab, accept a suggestion, and move on. By mid-2026, the same tools are reviewing pull requests, triaging incidents from PagerDuty alerts, posting summaries to Slack, and assigning reviewers based on time zones, all [...]
The Modern Developer: AI, Cloud, and What Comes Next
For the longest time, the standard advice for entering the technology industry was simple: learn to code. But as AI in software development becomes more common, knowing how to write code is no longer the whole story. At first it's like this: learn Python, JavaScript, Java, or another programming [...]
Agentic AI on AWS: From Terraform Modules to the Model Context Protocol
Most teams deploying AI on AWS were still running the same playbook: take a foundation model, wire up a retrieval layer, wrap it in an API Gateway endpoint, and call it a chatbot. By mid-2026, the same teams are deploying autonomous agents that reason through multi-step workflows, authenticate against [...]

Automating Publications with Claude, Canva, and n8n

Every business that runs a social media page knows the same repetitive cycle. Pick a topic. Write a caption. Design a graphic. Post it on schedule. Repeat tomorrow. Multiply that by every campaign, every seasonal push, every recurring content series, and it becomes a real operational cost, not just a marketing task. That repetitive cycle is exactly what a project called Automating Publications was built to solve. It is a working, experimental content pipeline [...]

AI Ethics Explained: How to Use Artificial Intelligence Responsibly

Have you ever used ChatGPT to help explain a difficult topic? Maybe you've asked Gemini to summarize a lengthy article, generate ideas for a school project, write an email, or even use Claude for brainstorming concepts. If you're a student, you've probably wondered: "Is it okay to use AI for assignments?" If you're a content creator, perhaps you've asked yourself at least once: "Who actually owns AI-generated content?" Or maybe you've come across AI-generated [...]

Fine-tuning an LLM for natural Tagalog speech

If you're an ML engineer or a technical lead planning to pre-train a large language model (LLM) for Tagalog or Taglish, how do you start? In this article, we walk through the process of defining a target voice, building a data pipeline, running a QLoRA training experiment, and evaluating results with native speakers, so a team can test the idea with a small, well-scoped proof of concept before committing to a larger build. Why [...]

Building Diffender: A Serverless AI Security Reviewer for GitHub Pull Requests with Amazon Bedrock

A pull request can pass its tests, satisfy its acceptance criteria, and still expose a production credential in one line of code. Diffender is an Amazon Bedrock pull request reviewer built to identify that kind of risk before the change reaches the main branch. However, human review remains essential, and its depth can vary with workload, time pressure, and security experience. Meanwhile, deterministic scanners provide valuable coverage, although their findings are not always presented [...]

AWS Certification Maintenance: Recertify Without an Exam

Many AWS-certified professionals face the same challenge every few years: preparing for another certification exam while balancing work, projects, and personal commitments. While certifications remain a valuable way to validate cloud expertise, the traditional recertification process can be time-consuming and stressful. To address this, AWS has introduced a new certification maintenance option that allows eligible professionals to extend select AWS Certifications without retaking the full exam. Through AWS Skill Builder, certification holders can complete [...]

CI/CD Crash Course: From Junior to Senior Developer

Continuous Integration and Continuous Delivery/Deployment (CI/CD) is the backbone of modern software teams. It's not just a buzzword for your resume — it's the automated pipeline that takes code from "it works on my machine" to "it works in production, reliably, every time." Understanding CI/CD deeply, not just using it, is one of the clearest markers separating a junior developer from a senior one. The Basics: CI vs CD Continuous Integration (CI) is the [...]

Everything You Need to Know About Harness Engineering

AI agents can now write code, browse the web, and run for hours without a human watching. Ask one to build a feature, and it might open ten files and call five tools. It can make a hundred small decisions before it ever shows you a result. That is a different animal from a chatbot answering one question. In my experience following this shift, it also breaks the old playbook for controlling AI behavior. [...]
