Building an Ethical Hacking Lab to Practice Every OWASP Top 10 Vulnerability

As a computer science student majoring in Network and Information Security, I have researched so many ways that I can actually learn more about cybersecurity. More specifically? Hacking. With the power of the internet, I came across so many courses, websites, and applications from which I can utilize to gain more understanding. They're helpful, yes. But at some point, I just asked myself… What if I just stop reading, and actually start doing? [...]

Physical AI in 2026: Why Mechatronics Matters

Many learners and engineers who focus on cloud and AI still think of intelligence as something that exists only in data centers or large language models. In 2026, a major shift is happening. AI is stepping out of the digital world and into the physical one. This is called Physical AI, also known as Embodied AI. It combines powerful foundation models with real-world robotics and mechatronic systems. For the first time, AI does not [...]

A Beginner’s Guide to Small Language Models (SLMs)

The Reality of Learning Tech: Mental Health, Pressure, and Growth

Learning technology is often described as exciting. It offers new skills, new opportunities, and a clear path forward. However, mental health in tech is often overlooked. But for many people, that journey does not always feel that way. Over the past year, while trying to grow in tech, I have also been navigating personal mental health challenges. There were days when learning something new was not just about understanding concepts. It was about finding [...]

Amazon Quick Sight Sheet Tooltips: Enhancing Data Storytelling and Dashboard UX

Modern organizations use data visualization tools for critical decisions. Dashboards simplify complex datasets, turning millions of rows of raw data into digestible formats. Still, users often view a dashboard and feel they aren't seeing the whole picture. Dashboards often lack immediate context, resulting in a frustrating user experience. Analysts must constantly switch between views, tabs, and reports just to understand the insights. To solve this, AWS introduced Sheet Tooltips in Amazon Quick Sight, a [...]

Finsharc, a Newcomer Reshaping How We Think About Personal Finance

Finsharc is a personal finance application that is entering a very saturated place. As there are personal finance apps such as Money Manager that already solve the basics of expense tracking at a personal level, (things you buy day-to-day, such as lattes or groceries) budgeting for the future, and reporting with pie charts. Those things have already been solved. But most of these traditional applications are stable, yet entirely rigid. Finsharc, which is a [...]

Google Lyria 3: Free AI Music in Gemini

Google quietly rolled out Lyria 3 inside Gemini, and it lets anyone generate 30-second music tracks from a text prompt, complete with vocals, lyrics, and instrumentals. It's free, it's surprisingly good, and most people don't even know it's there. I spent an afternoon messing around with it. Here's how it works and where it starts to fall apart. What Is Lyria 3? Lyria 3 is Google DeepMind's music generation model. It lives inside the [...]
