RAID: Why Everyone Should Care?

RAID, or Redundant Array of Independent Disks, is a core technology that powers everything from personal NAS drives to enterprise-grade data centers. It enables you to combine multiple physical hard drives into a single system that improves performance, enhances data redundancy, or balances both. This blog post breaks down what RAID is, how the most common RAID levels work, and what their strengths and trade-offs are. Whether you are setting up your first home server or architecting high-availability infrastructure, understanding RAID is essential.

Takeaways on ChatGPT Codex

This article explores how software developers can integrate ChatGPT Codex into their development workflows, from initial code generation to pull request creation. Codex is OpenAI’s code-focused large language model, capable of reading and writing code, generating test cases, and interacting with GitHub repositories. We explain how to get the most out of Codex by combining it with unit tests and test-driven development (TDD), ensuring reliable and verifiable results. Drawing on real-world advice from Simon Willison, we emphasize why automated testing is not just a complement but a critical enabler of safe and effective AI-assisted software engineering.

Beyond the Buzzwords: What Is Machine Learning, Really?

Machine learning is transforming industries, but at its core, it remains a field built on mathematics, logic, and structured data modeling. This article walks through the foundational principles of machine learning, stripping away the modern layers of abstraction to focus on its original essence. No libraries, no black boxes, just math and reasoning. Whether you’re a beginner with a math background or a curious technologist aiming to understand what actually powers intelligent systems, this is a ground-up journey into how machines learn.

Non-Relational Databases and the Design Dilemma: Single Table or Multi Table?

Non-relational databases have changed how developers think about data modeling. Among them, Amazon DynamoDB stands out for its speed, scalability, and serverless simplicity. This post explores the core ideas behind non-relational databases, explains the philosophies and tradeoffs of single-table versus multi-table designs in DynamoDB, and offers clear conventions and examples to guide implementation.

From Idea to App: Going Serverless with AWS

Startups and solo developers are often faced with the same challenge: how to build robust, scalable systems without draining their limited resources. Traditional cloud services offer power, but can be overkill — both in terms of complexity and cost. This is where serverless technology shines. In this post, we’ll look at how combining the Serverless Framework, AWS Lambda, and DynamoDB creates a lean, efficient stack. We’ll also examine why Aurora Serverless (particularly v2) may not be the best fit for budget-conscious builders, and when a cheap VPS still makes sense for relational workloads.

The AI Trap: Why Replacing Junior Engineers Might Cost Us the Future

AI is changing how we build software—faster, smarter, and increasingly without junior developers. But replacing entry-level roles with AI may leave us with a future shortage of experienced engineers who understand systems deeply enough to guide that same AI. This post explores why mentoring and experience still matter, and how we can build a sustainable path forward.

From Code to Ownership: The Rise of Ethereum and Solidity in Real-World Applications

Ethereum is more than just a cryptocurrency—it’s a programmable platform that brought the concept of decentralized logic to blockchain technology. Solidity, Ethereum’s primary programming language, is what developers use to build decentralized applications (dApps) and smart contracts. This blog series breaks down how Ethereum and Solidity work, explores why they’re revolutionary technologies, and highlights successful real-world applications from decentralized finance to tokenized real estate.

Beyond Twitter and Bluesky: Building the Social Web We Actually Want with Mastodon

As the cracks in centralized platforms like Twitter (now X) deepen, alternatives like Mastodon and Bluesky are racing to reshape the social internet. But while both offer something new, only one fully commits to the core principles that made the early internet great: decentralization, user ownership, and community-driven governance.

This post unpacks the real differences between Mastodon, Bluesky, and Twitter — and explains why Mastodon isn’t just an alternative. It’s the future we should be rooting for.
