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
Have you ever watched Tony Stark boot up his suits and wished you had your very own J.A.R.V.I.S. to help you code, research, or just manage your day? If you are just starting out with web development, you have probably noticed that most AI chatbot tutorials look exactly the [...]
Can’t Use the Terminal, Can’t Defend the Network: The Importance of Cybersecurity Degrees in the Philippines
Can't Use the Terminal, Can't Defend the Network: The Importance of Cybersecurity Degrees in the Philippines Open a job posting for a Security Operations Center (SOC) analyst, a penetration tester, or a systems administrator anywhere in the world, and one requirement shows up again and again: comfort with the [...]
PromptWars hackathon: students built AI apps
On June 20, 2026, thirty junior and senior high school students spent a day at Programmable Makati building working AI applications. The event was PromptWars: AI-Powered, Student-Built, a hackathon run by DEVCON Kids Philippines and Tutorials Dojo. This event demonstrated how beginners can build with high impact solutions [...]

Automating PII Detection and Redaction with Amazon Comprehend

Organizations today are entrusted with enormous amounts of sensitive information. Customer support logs, healthcare records, financial transactions, and even training datasets often contain Personally Identifiable Information (PII) such as names, phone numbers, email addresses, or credit card numbers. Protecting this information is not just a matter of compliance with regulations like GDPR, HIPAA, or PCI DSS. It is also central to maintaining customer trust and reducing the risk of data breaches. Amazon Comprehend, a [...]

Build a Model-Agnostic AI Text Summarizer Web Extension

Browser extensions are a great way to bring AI directly into your everyday workflows. Instead of copying text into external tools and websites to be summarized, you can do it right on the page. In this tutorial, we'll build a lightweight, model-agnostic Chrome extension that summarizes selected text using AI. With a simple right-click, users can send any highlighted text to an AI model of their choice and instantly view a concise summary in [...]

AWS Lambda Managed Instances: Serverless Simplicity with EC2 Control

AWS Lambda Managed Instances marks a significant evolution in serverless computing. For years, standard Lambda was the default for running code without infrastructure management, but it offered limited control over the underlying hardware. This new capability changes that by combining serverless simplicity with Amazon EC2 flexibility. Announced at AWS re:Invent 2025, this feature enables Lambda functions to run on designated Amazon EC2 instances. You choose the hardware configuration, while AWS manages the infrastructure. [...]

How to Generate Simple Document Embeddings with Python

Document embeddings are one of the simplest ways to give machines an understanding of text, and in our previous article, Document Embeddings Explained: A Guide for Beginners, we explored how they turn entire documents into dense numerical vectors that capture meaning and context. Now that you understand what embeddings are and why they’re useful for tasks like semantic search, classification, and clustering, this tutorial will show you how to generate them in practice using [...]

Open Cybersecurity Schema Framework (OCSF) and Amazon Security Lake

Amazon Security Lake is a managed service that collects and stores security logs from AWS services, on-premises systems, and supported third-party tools. It automatically converts all incoming data into Apache Parquet and formats everything using the OCSF schema. This setup allows different kinds of security logs to follow one consistent structure instead of having separate formats. With this unified approach, teams no longer need to decode or reorganize data manually because Security Lake handles [...]

Can Gemini 3 Replace My AI Toolkit?

I've always approached AI with one mindset: use whatever tool gets the job done fastest and cleanest. I'm not loyal to one model, one company, or one ecosystem. I switch between tools depending on what my day looks like. In school, that might mean summarizing academic papers. At work or during self-study, that might mean debugging code or reviewing a cloud diagram. For daily life, it might just mean drafting an email or organizing [...]

AWS Vector Databases Explained: Semantic Search and RAG Systems

The generative AI (GenAI) revolution has transformed how organizations extract value from their data. While large language models (LLMs) demonstrate remarkable capabilities in understanding and generating human-like text, their true enterprise potential is unlocked only when they can access proprietary, domain-specific information. This necessity has propelled vector databases from a specialized niche into an essential pillar of modern AI infrastructure. But First, What Are Vector Databases? A vector database, as its name suggests, is [...]

Self-Hosting Judge0: A Step-by-Step Guide Using Amazon EC2, Lambda, and S3

Judge0 is a powerful, open-source code execution system widely used by online coding platforms to run programs in secure environments. However, while it is often accessed as a third-party service, self-hosting Judge0 on AWS significantly grants you complete control over configuration and security. In fact, this level of ownership is essential for handling sensitive data or customizing language support. Moreover, self-hosting enables greater scalability, thereby allowing you to adapt the system as your requirements [...]

The Cash Cow + Investment Model: A Career Blueprint from Tutorials Dojo’s CEO

Imagine spending weeks building a course, only to watch it fail. That’s exactly what happened in 2019 to the founder of Tutorials Dojo, Jon Bonso. He had spent weeks building a React Native course. He recorded, edited, and re-recorded, hoping people would buy it. However when it finally launched, the effort didn’t match the reward. It was one of those career-defining moments where you ask yourself: “Am I even in the right industry?” Instead [...]
