Linux

Revolution OS is a 2001 documentary film that traces the twenty-year history of GNU, Linux, open source, and the free software movement.

Linux (LIN-uuks) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license.

The Code is an English-language Finnish documentary about Linux from 2001, featuring some of the most influential people of the free software movement.

Boxee Box by D-Link (officially "D-Link Boxee Box DSM-380") is a Linux-based set-top device and media extender that first began shipping in 33 countries worldwide on 10 November 2010. Designed to easily bring Internet television and other video to the television via Boxee's software, it comes pre-installed with Boxee media center software. The hardware is based on the Intel CE4110 system-on-a-chip platform (that has a 1.2 GHz Intel Atom CPU with a PowerVR SGX535 integrated graphics processor), 1 GB of RAM, and 1 GB of NAND Flash Memory. The DM-380 features an HDMI port (version 1.3), optical digital audio (S/PDIF) out, an RCA connector for analog stereo audio, two USB ports, an SD card slot, wired 100BASE-TX Ethernet, and built-in 2.4 GHz 802.11n WiFi. The Live TV dongle, which started shipping in February 2012, enables users to watch digital OTA or Clear QAM cable television channels with EPG.

The Steam Deck is a handheld gaming computer produced by Valve Corporation, designed to run a portion of games available on the Steam storefront client. Built upon the experiences gained from Valve's earlier ventures with Steam Machine and the Steam Controller, the Steam Deck integrates a custom AMD APU and SteamOS, a Linux-based operating system. The Steam Deck represents Valve's pivot towards a fully in-house hardware development approach, following the challenges faced with Steam Machines' reliance on OEMs and the requirement for native Linux game support.

The BlackDog is a pocket-sized, self-contained computer with a built-in biometric fingerprint reader which was developed in 2005 by Realm Systems, which is plugged into and powered by the USB port of a host computer using its peripheral devices for input and output.

Linux began in 1991 as a personal project by Finnish student Linus Torvalds to create a new free operating system kernel. The resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 4.15 version in 2018 with more than 23.3 million lines of source code, not counting comments, under the GNU General Public License v2 with a syscall exception meaning anything that uses the kernel via system calls are not subject to the GNU GPL.
