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 [...]
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 [...]

Claude Mythos Explained, is it an AI Breakthrough or Overhyped Cybersecurity Threat?
The announcement of Claude Mythos stirred the community towards the advancement of large language models and their application within the domain of cybersecurity. For more than two decades, the investigation and discovery of zero-day vulnerabilities have rested upon cybersecurity teams and researchers. However, the announcement of Claude Mythos, by [...]
AI Workflows vs AI Prompts: What’s the Real Difference
At first, using AI feels simple. You type a prompt, get a response, and move on. That’s how most people start, and for basic tasks, it works. But as you try to do more complex or repeatable work, you begin to notice something: prompts alone aren’t enough. This is where [...]
AI Agents on Azure: Practical Insights for Learners
Many people learning Azure still struggle with repetitive manual tasks. AI Agents on Azure for learners offer a practical way to handle these challenges. When a 2 AM alert fires, the usual process involves manually checking the cause, reviewing affected processes, and examining the whole system. AI agents can [...]

Simplifying DNS Management: How to Transfer Your Domain’s DNS from GoDaddy to Amazon Route 53

If you have ever tried to create a website and wanted it to be accessible through a custom web address, then you have already touched the basics of DNS, or Domain Name System. DNS is what connects your domain name to the actual server where your website lives. It plays a critical role in making sure your site is reachable, fast, and secure for users around the world. Many website owners start by [...]

Google Veo 3: The Latest Breakthrough in AI Video Generation

Artificial intelligence has come a long way from its early days when it could only do simple tasks like solving math problems, playing basic games, or following step-by-step instructions from programmers. Back then, AI relied on fixed rules and couldn’t learn or improve on its own. As technology advanced, AI became more capable and useful. It learned to recognize voice commands, identify faces, suggest videos based on viewing habits, and learn patterns from data. [...]

Why I Chose AWS Lambda to Power My App’s Cloud Logic

For this article, I will demonstrate how I used AWS Lambda as an all-around backend system for a mock-up mobile application I developed for my Design subject in school. The mobile application is an IoT application that integrates communication between a mobile device and a handheld barcode scanner using a Bluetooth module. It also includes security functions, such as code decryption and user statuses. For the dependencies, I used flutter_blue, get, and http. The [...]

What is Area Under the ROC Curve (AUC) in Machine Learning?

Area Under the ROC Curve (AUC) Cheat Sheet AUC, short for Area Under the Curve of the Receiver Operating Characteristic (ROC), is a metric that evaluates how well a model can differentiate between different classes. A performance metric primarily used for binary classification models. Ranges from 0 to 1: 1: Perfect model. 0.5: Model performs no better than random guessing. 0: Model inversely ranks positives and negatives. Accurate Outcomes True Positive (TP): The model [...]

What is BiLingual Evaluation Understudy (BLEU) Score for Machine Translation?

BiLingual Evaluation Understudy (BLEU) Score Cheat Sheet BLEU (BiLingual Evaluation Understudy) is a corpus-level metric designed to automatically evaluate the quality of machine-generated text, most commonly in machine translation (MT). It compares n-gram overlap between the machine’s output and one or more human reference translations. Introduced by Papineni et al. (2002), BLEU became the first automated metric to correlate highly with human judgments in large-scale MT evaluations. It remains a widely used baseline for evaluating [...]

What is RLHF – Reinforcement Learning from Human Feedback?

What is Reinforcement Learning from Human Feedback (RLHF)? A technique to improve AI models using human feedback to guide learning. Builds on reinforcement learning, where AI learns by trial and error to achieve goals. Uses human opinions to determine good or bad outputs, enhancing traditional reward systems. How RLHF Works Data Collection: AI generates multiple outputs (e.g., answers or text snippets). Humans provide feedback by ranking or comparing outputs (e.g., which is better or [...]
