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, call five tools, and make a hundred small decisions before it ever shows you a result. That's a different animal [...]
Should Philippines Make Its Own Local Large Language Model?
As countries all around the world are beginning to seriously invest in their own models, there is a growing debate on whether the country should create its own local large language model. If we do, would it be cost-effective? And if it is, would it be beneficial? As [...]
How to Balance Business Goals with User Needs in UI/UX: A Data-Driven Approach
The Tug-of-War Balancing business goals with user needs in UI/UX is a challenge every designer eventually runs into. Users want fast, free, and beautiful experiences with no friction anywhere.

UI/UX Design: Speeding Up the Creative Process with AI
The Builder's Mindset If you have ever stared at a blank Figma canvas with a deadline looming — a thesis defense, a hackathon demo, or just a personal app idea you finally want to ship — you already know that speed matters as much as polish. A traditional UI/UX [...]
Agentjacking: How Fake Sentry Errors Hijack AI Coding Agents
AI coding agents like Claude Code, Cursor, and Codex now do far more than autocomplete. They read source code, query observability platforms, open pull requests, and run terminal commands on developer machines. That expanded access is useful, but it also creates a problem most security teams have not accounted [...]
Build AI Apps Faster with Google AI Studio and Gemini
Artificial intelligence has become an essential part of modern software development. It helps developers build applications that understand natural language, generate content, analyze documents, write code, and automate complex tasks. While large language models (LLMs) make these features easier to use, integrating them into real applications still takes time. [...]
OpenRouter Explained: Access Multiple AI Models Through One API
The rapid advancement of generative AI has given developers access to an ever-growing collection of large language models from providers such as OpenAI, Anthropic, Google, Meta, Mistral AI, and xAI.

Crowd Detection: How AI Predicts Busy Areas

You might use Google Maps in your daily commute, but have you ever wondered how it provides real-time traffic data? Or how it highlights the busiest areas and even the popular times for a business? To achieve this, Google powers these features with large-scale analysis and crowdsourcing from our smartphone location data. Subsequently, an artificial intelligence (AI) application is used to also predict crowd levels in the coming hours and days, instead of being [...]

Terraform vs AWS CloudFormation: Which Is Better for Building Serverless Applications?

Serverless applications feel effortless — until you try to scale. You might start with a single AWS Lambda function. Soon, you add API Gateway endpoints, DynamoDB tables, S3 triggers, SNS notifications, and maybe Step Functions to orchestrate your workflow. Before long, your AWS console looks like a maze, and manual management becomes nearly impossible. Serverless doesn’t mean there are no servers. It means you don’t manage them. AWS handles provisioning, scaling, and maintenance while [...]

Data Preprocessing Guide for Beginners in ML

Before machine learning (ML) models can generate predictions or insights, the raw data must first be cleaned, organized, and transformed into a suitable format for the model. This process is known as data preprocessing. It is the foundation of every successful ML project. It ensures that the model learns from high-quality, consistent, and well-structured input rather than noisy, incomplete, or biased information. In this hands-on guide, we’ll walk through how to transform a raw [...]

Amazon Bedrock + Promptfoo: Rethinking LLM Evaluation Methods

I discovered something embarrasing about my LLM development workflow last month. After spending hours crafting what I thought was the perfect prompt for a customer service chatbot on Amazon Bedrock, I deployed it and called it done. My validation process? I asked it five questions, nodded approvingly at the responses, and moved on. Sound familiar? This "vibe-based prompting" approach worked fine until the chatbot confidently told a user that our fictional company offers "24/7 [...]

Tech Burnout: Is It Really Inevitable?

What if the dream job, the one you've always been dreaming of and manifesting ever since, is quietly draining the life out of you? This exhaustion is a known feeling in the tech industry, where the relentless pressure forces professionals and students to push until they hit a wall. This struggle is intensified in cultures that value sheer willpower and "diskarte" (resourcefulness), where admitting this profound fatigue feels like a personal, silent failure. We've [...]

Rise of Microservices in Modern Apps: From One Block to Many

Have you ever thought about the pain of fixing just one small piece of a massive software system without accidentally breaking everything else? Honestly, most of the time, that is almost impossible. That challenge led to the rise of microservices in modern apps. It marked a shift from old monolithic architectures to smaller and independent services. This represents a significant architectural change. Developers moved away from huge, rigid monolithic setups and embraced smaller, independent systems. [...]

High-Performing ≠ Massive: The Rise and Progression of Small Language Models (SLMs)

Have you ever needed to find a new charger for your device, only to discover that its voltage wasn’t compatible, causing it not to work or even risking damage? Without checking the actual needs of your device, you’ve probably thought that you could go with what the seller recommends as the “highest quality” rather than your device’s fitting needs. With the current utilization of AI for businesses, bigger doesn’t always mean better. Large Language [...]
