16+ min ago (989+ words) Software systems often grow over time, and with growth comes the need for flexibility. You might want to add new features, support new formats, or integrate with new systems without modifying the core application each time. This is exactly where a plugin architecture shines. In this post, we'll walk through how to build a lightweight plugin architecture using Java's Service Provider Interface (SPI). We'll also describe a practical example involving greeting messages in multiple languages. The main objective of this post is to make people familiarize with the plugin architecture in a simple way. A Plugin Architecture is a software design pattern that allows for the core functionality of an application to be extended, modified, or customized without changing the core application's source code. New functionality is packaged as small, independent modules called plugins, which the main application discovers and…...

34+ min ago (710+ words) Look, I'll be honest with you. I've written my fair share of Redux reducers. I've stared at action creators at 2 AM wondering why my state wasn't updating. I've debugged Flux architectures until my eyes bled. Then I started working with Blazor and thought: "Great, now I get to do this all over again in C#." Here's a pattern you've probably seen a thousand times: Three files. Three concepts. One simple operation: add 1 to a number. I kept asking myself: why do we need all this ceremony? React figured it out with Zustand and Jotai. Why is .NET still stuck in 2015? That's it. That's the whole thing. Your state is a C# record. Your "actions" are just methods that return new state. No dispatchers. No reducers. No action types. Just pure functions on immutable data. And in your component: The base…...

47+ min ago (1545+ words) PostgreSQL databases power critical applications across industries, from startups to Fortune 500 companies. Yet many organizations discover their backup strategies are inadequate only after disaster strikes. A well-designed backup approach protects against hardware failures, human errors, ransomware attacks, and natural disasters " ensuring your data survives whatever challenges arise. This guide presents 13 essential backup best practices that every developer and DBA should implement. Whether you're managing a single database or hundreds of PostgreSQL instances, these practices will help you build a robust, reliable backup strategy that meets both operational and compliance requirements. Recovery Point Objective (RPO) defines the maximum acceptable data loss measured in time. If your RPO is one hour, you must back up at least hourly. Recovery Time Objective (RTO) defines the maximum acceptable downtime " how quickly you must restore service after a failure. These two metrics together determine your…...

I met a few founders there and asked each of them to describe the very beginning of their entrepreneurial journey. If you've ever daydreamed about starting something on your own but didn't know where to begin, you'll see that even successful founders once stood exactly where you are. In this article, you won't find polished success stories. This is where you'll get to know how the leap from employee to founder truly feels like.

1+ hour, 4+ min ago (1555+ words) It was supposed to be a smooth EKS migration. Instead, a handful of users started complaining about painfully slow logins " 20 to 40 seconds long. Oddly, others saw no issue at all. What followed was a three-hour debugging marathon that took us through Cloudflare cache rabbit holes, pod benchmarking, and finally, an AWS ALB subnet misconfiguration. What makes this story worth telling is not just the root cause (a bad ALB IP), but the full forensic process " every command, every false lead, and the eventual breakthrough. This is an engineering playbook, shared so you don't waste the same hours the next time you face an intermittent latency mystery. This post walks the entire forensic process: the commands we ran (copy/paste-ready, with safe placeholders), the exact timings and outputs we observed (sensitive values redacted), the conclusions at each step, the mistakes and…...
