🧱Modern databases are built to stay consistent, reliable, and resilient — even when systems crash or multiple users access data at once.Three major mechanisms that make this possible are Transactions, Deadlocks, and Log-Based Recovery. In this guide, we’ll explore how each of these works in practice using a simple DB_Assignment table as an example. 🧱…

In the first part of this series, we built a simple, command-line-only RAG application. In this post, we’ll turn our command-line application into a web API using FastAPI. The Goal for This Post By the end of this post, you will have a web API that can answer questions about the documents in the data…

A Brief History of Threads in JavaJava 21 is a new Long-Term Support (LTS) release. Honestly, I’ve been using Java 17 for a long time and wasn’t sure why I should upgrade to Java 21 or what benefits it would bring. It turns out that Java 21 introduces many performance optimizations, particularly in the area…

Indexes are one of the most effective ways to enhance SQL query performance. In this tutorial, we’ll dive into B-Tree Index, B+ Tree Index, and Hash Index using a simple Students table in Oracle LiveSQL. 🧱 Step 1: Set Up the Students Table Let’s begin by creating a Students table with columns for roll number,…

APIs often rely on HMAC signatures to verify the authenticity and integrity of requests.Whether you’re validating webhooks, securing IoT messages, or signing API payloads, it’s crucial to confirm that your HMAC implementation works correctly — and that both client and server generate the same signature. That’s where a free testing tool helps. 🔐 What Is…

If you’ve played around with AI chatbots like Gemini or ChatGPT, you know they’re super smart, but they have one huge flaw: they forget everything. Every time you ask them something, it’s a completely new request. They don’t remember what happened last time, and they don’t know anything about your personal files or documents. It’s…

TL;DR Python is having a moment—its adoption jumped notably year-over-year, propelled by AI, data, and back-end work. Rust and Go are steadily rising too. AI is now table stakes. 8 in 10 devs report using GPT models for development tasks, with Claude and Gemini in the mix; devs also say AI causes new frictions they…

Hey everyone 👋 I’ve just open-sourced Create Express Auth — a production-ready Express + TypeScript boilerplate designed around Clean Architecture and Hexagonal principles. After years of developing APIs with Node and Express, I realized most projects start fast, but scale badly. Adding features, tests, or new modules becomes painful because the core logic is tied…
