Database under construction, we’re fixing its broken soul.

1. What Is Linux?

Linux is a free and open-source operating system kernel first released by Linus Torvalds in 1991. It powers a wide range of devices—from servers and desktops to smartphones, smart TVs, game consoles, and even embedded systems.

Often bundled with GNU software and used in many distributions (distros), Linux is known for its stability, security, and flexibility, forming the backbone of modern computing infrastructures worldwide.

2. Key Features of Linux

Open-source codebase: completely free to use, modify, and distribute under the GPL license.

Modular architecture: highly customizable kernel and system components for different use cases.

Command-line power: advanced control and automation via shell (Bash, Zsh, etc.).

Multi-user environment: built with security and permission separation in mind.

Multi-platform support: runs on everything from Raspberry Pi and old PCs to enterprise-grade servers.

4. Use in Gaming and Development

Once considered difficult for gaming, Linux now supports major titles through Steam Proton, Wine, and native ports. It’s also a favorite OS for developers, hackers, and enthusiasts thanks to its flexibility and full control.

Game emulation: a hub for retro emulators like RetroArch, MAME, and Dolphin.

Game dev platforms: engines like Godot and Unity support Linux natively.

Steam Deck OS: Valve’s Steam Deck runs on a Linux-based SteamOS platform.

5. Legacy and Community

Linux has reshaped the computing world. Its community-driven development model, vast documentation, and transparency have made it a long-lasting foundation for innovation across industries.

Powered by community: developed and maintained by thousands of contributors globally.

Foundational tech: used in Android, web servers, IoT, cloud, and beyond.

Ever-evolving: Linux remains one of the most respected, secure, and future-proof OSes today.
