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. The business, meanwhile, wants high conversion rates, low hosting costs, and a fast time-to-market. These two wish lists are not always [...]
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. Each model offers different strengths, whether in reasoning, code generation, content creation, multilingual support, or cost efficiency. While having [...]
Build Your Own JARVIS AI Chatbot Interface using Vercel

Far from being a mere technical skill, Prompt Engineering shapes the interaction between humans [...]

Monitoring Amazon SES Complaint Rates with CloudWatch Alarms and Real-Time Slack Notifications

Amazon Simple Email Service (SES) is a powerful tool for sending high volumes of emails quickly and efficiently. However, to maintain your email-sending capabilities and ensure high deliverability, it's essential to monitor your sender's reputation closely. One key metric for assessing this reputation is the Complaint Rate, which measures how often recipients mark your emails as spam. A high complaint rate can lead to your emails being filtered into spam folders, throttling, or even [...]

Methods in Evaluating Foundation Model Performance

A foundation model is a large-scale, pre-trained artificial intelligence model that serves as a general-purpose system for various downstream tasks. These models, such as GPT for natural language processing or CLIP for vision-language understanding, are trained on extensive datasets and can be fine-tuned or adapted to specific applications. Foundation models are characterized by their ability to generalize across tasks, making them highly versatile and impactful in AI-driven solutions. Evaluating these models' performance is essential to [...]

Amazon SES Complaint Rate: What It Is and How to Manage It

Email remains one of the most effective ways of communication for businesses in today's digital age. It allows you to reach out to current and potential customers through newsletters, promotions, important information, and updates about your products and services. Whether it is to keep your customers engaged, promote your new offerings, or send transactional messages like order confirmations and such, email is a simple yet very powerful approach to improve your connection with clients [...]
