BusyBox
BusyBox is a software suite that provides several List of Unix commands, Unix utilities in a single executable file. It runs in a variety of POSIX environments such as Linux, Android (operating system), Android, and FreeBSD, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. The authors dubbed it "The Swiss Army knife of Linux on embedded systems, Embedded Linux", as the single executable replaces basic functions of more than 300 common commands. It is released as free software under the terms of the GNU General Public License, GNU General Public License v2, after controversially deciding not to move to GNU General Public License#Version 3, version 3. History Origins Originally written by Bruce Perens in 1995 and declared complete for his intended usage in 1996, BusyBox initially aimed to put a complete Booting, bootable system on a s ...

Software Freedom Law Center
The Software Freedom Law Center (SFLC) is an organization that provides ''pro bono'' legal representation and related services to not-for-profit developers of free software/open source software. It was launched in February 2005 with Eben Moglen as chairman. Initial funding of US$4 million was pledged by Open Source Development Labs. A news article stated: GPL version 3 SFLC represented and advised the Free Software Foundation, one of its principal clients, throughout the process of drafting and public discussion of version 3 of the GNU General Public License (GPLv3) during 2005–2007. Along with FSF president Richard M. Stallman, SFLC director Eben Moglen and then-SFLC counsel Richard Fontana were principal authors of GPLv3, LGPLv3, and the GNU Affero General Public License. BusyBox litigation During 2007 and 2008, SFLC filed a series of copyright infringement lawsuits against various defendants, on behalf of Erik Andersen and Rob Landley, the principal developers ...

Toybox
Toybox is a free and open-source software implementation of over 200 Unix command line utilities such as '' ls'', '' cp'', and '' mv''. The Toybox project was started in 2006, and became a 0BSD licensed BusyBox alternative. Toybox is used for most of Android's command-line tools in all currently supported Android versions, and is also used to build Android on Linux and macOS. All of the tools are tested on Linux, and many of them also work on BSD and macOS. Functionality and aim Toybox aims to provide a BSD licensed replacement for the GPL licensed BusyBox. Toybox's major technical design goals are simplicity, smallness, speed and standard compliance. Toybox aims to be mostly POSIX-2008 and LSB 4.1 compatible, and doesn't focus on having every option found in GNU counterparts. Toybox is licensed using the permissive 0BSD license, where BusyBox uses the copyleft GNU General Public License, which led to different usage domains. BusyBox is mostly used in the copyleft FOS ...

GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), 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. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

Monsoon Multimedia
Monsoon Multimedia was a company that manufactured, developed and sold video streaming and place-shifting devices that allowed consumers to view and control live television on PCs connected to a local (home) network or remotely from a broadband-connected PC or mobile phone. It was one of 5 major transformations (1st VGA in 1984, 16 bit audio and mixed signal ASICs in 1992, 1st commercially available CD Rom drive less than $100 in 1992, MPEG-2 adapters in 1996 and high compression software for mobile phones in 2001) initiated by Prabhat Jain, a Silicon Valley entrepreneur with 5 undergraduate and post graduate engineering degrees from Cal Berkeley and Univ of Vienna, Austria. On the even of Cisco acquiring Monsoon in 2017, EchoStar, the new parent of Sling sued Monsoon for patent infringement (of the Japanese patents), having obtained confidential information about the date of the acquisition by Cisco from a Monsoon employee under murky circumstances. Monsoon settled the lawsuit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux For Mobile Devices
Linux for mobile devices, sometimes referred to as mobile Linux, is the usage of Linux-based operating systems on portable devices, whose primary or only Human interface device (HID) is a touchscreen. It mainly comprises smartphones and tablet computers, but also some mobile phones, personal digital assistants (PDAs) portable media players that come with a touchscreen separately. Mobile Linux is a relatively recent addition to the Linux range of use, with Google's Android operating system pioneering the concept. While UBPorts tried to follow suit with Ubuntu Touch, a wider development of free Linux operating systems specifically for mobile devices was only really spurred in the latter 2010s, when various smaller companies started projects to develop open source phones. Lists Operating systems This is a list of Linux distros directly targeted towards use with mobile phones, being offered preconfigured with the mobile-oriented software listed below. There are both phone produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Router Project
The Linux Router Project (LRP) is a now defunct networking-centric micro Linux distribution. The released versions of LRP were small enough to fit on a single 1.44MB floppy disk, and made building and maintaining routers, access servers, thin servers, thin clients, network appliances, and typically embedded systems next to trivial. History LRP was conceived and primarily developed by Dave Cinege from 1997 until 2002. It began originally as a 'router on a floppy' and evolved into a streamlined general purpose network operating system. As LRP is the oldest embedded Linux distribution, it formed (in whole or in part) the basis of many other embedded system distributions and commercial products which followed it. Several parts developed or specifically enhanced for LRP are still found in common usage today such as POSIXness and BusyBox BusyBox is a software suite that provides several List of Unix commands, Unix utilities in a single executable file.

POSIX
The Portable Operating System Interface (POSIX; ) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. POSIX defines application programming interfaces (APIs), along with command line shells and utility interfaces, for software compatibility (portability) with variants of Unix and other operating systems. POSIX is also a trademark of the IEEE. POSIX is intended to be used by both application and system developers. As of POSIX 2024, the standard is aligned with the C17 language standard. Name Originally, the name "POSIX" referred to IEEE Std 1003.1-1988, released in 1988. The family of POSIX standards is formally designated as IEEE 1003 and the ISO/IEC standard number is ISO/ IEC 9945. The standards emerged from a project that began in 1984 building on work from related activity in the ''/usr/group'' association. Richard Stallman suggested the name ''POSIX'' to the IEEE instead of the former ''IEEE-IX''. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Space
A modern computer operating system usually uses virtual memory to provide separate address spaces or regions of a single address space, called user space and kernel space. This separation primarily provides memory protection and hardware protection from malicious or errant software behaviour. Kernel space is strictly reserved for running a privileged operating system kernel, kernel extensions, and most device drivers. In contrast, user space is the memory area where application software and some drivers execute, typically with one address space per process. Overview The term user space (or userland) refers to all code that runs outside the operating system's kernel. User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc. Each user space process usually runs in its own virtual memory space, and, unless explici ...
