Understanding NimbleParsec in Elixir: Building Powerful Parsers with Ease

Parsing is everywhere in software development — from configuration files to query languages, from log analysis to domain-specific languages. Yet many developers shy away from building custom parsers, thinking they’re complex and difficult to maintain. Enter NimbleParsec, an Elixir library that makes parser construction not just approachable, but genuinely enjoyable. What Makes NimbleParsec Special? NimbleParsec […]

Why Elixir Outshines Ruby on Rails in Modern Web Development

Elixir, Ruby / Yatender Singh

The web development landscape has changed dramatically since Ruby on Rails revolutionized it in 2004. What once felt like magic now shows its age in a world demanding real-time interactions, massive concurrency, and bulletproof reliability. It’s time to have an honest conversation about why Rails, despite its historical significance, is becoming a liability for serious

Kernel Polling in the BEAM VM: Unlocking Massive I/O Scalability in Elixir & Erlang

Elixir / Yatender Singh

Kernel Polling in the BEAM VM (Erlang/Elixir) What is Kernel Polling? Kernel polling is a technique where the operating system provides a way for applications to efficiently monitor many I/O resources (like sockets or files) at once. Instead of the application repeatedly checking each resource (polling), the OS notifies the application when any resource is

The Ultimate WebSocket Battle: Elixir vs Go Performance Showdown

Elixir, Websocket / Yatender Singh

Most performance comparisons are either unfair or unrealistic. We’ve all seen the “nuclear stress tests” that push systems to the brink, yielding little insight into real-world performance. This isn’t one of those. I wanted to find out, under a fair and realistic workload, which platform truly shines for high-concurrency WebSocket applications: Elixir’s elegant, actor-based concurrency
