OSTree
libostree (previously OSTree) is a system for versioning updates of Linux-based operating systems. It can be considered "Git Git () is a distributed version control system that tracks versions of files. It is often used to control source code by programmers who are developing software collaboratively. Design goals of Git include speed, data integrity, and suppor ... for operating system binaries". It operates in userspace, and will work on top of any Linux file system. At its core is a Git-like content-addressed object store with branches (or "refs") to track meaningful file system trees within the store. Features OSTree is closely inspired by Git. It operates on commits which refer to filesystem trees. To refer to different commits while maintaining a user-readable name, OSTree provides "references" (analogous to branches in Git), such as exampleos/buildmain/x86_64-runtime. Files provided by commits are by default immutable, done by mounting the filesystem itself ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flatpak
Flatpak is a utility for software deployment and package management for Linux. It provides a sandbox environment in which users can run application software in (partial) isolation from the rest of the system. Flatpak was known as xdg-app until 2016. Features Applications using Flatpak need permissions to access resources such as Bluetooth, sound (with PulseAudio), network, and files. These permissions are configured by the maintainer of the Flatpak and can be added or removed by users on their system. Another key feature of Flatpak allows application developers to directly provide updates to users without going through Linux distributions, and without having to package and test the application separately for each distribution. Because Flatpak runs in a sandbox (which provides a separate, ABI-stable version of common system libraries), it uses more space on the system than common native packages. However, OSTree, a technology underlying Flatpak, deduplicates matching fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Data Structure
In computer science, a data structure is a data organization and storage format that is usually chosen for Efficiency, efficient Data access, access to data. More precisely, a data structure is a collection of data values, the relationships among them, and the Function (computer programming), functions or Operator (computer programming), operations that can be applied to the data, i.e., it is an algebraic structure about data. Usage Data structures serve as the basis for abstract data types (ADT). The ADT defines the logical form of the data type. The data structure implements the physical form of the data type. Different types of data structures are suited to different kinds of applications, and some are highly specialized to specific tasks. For example, Relational database, relational databases commonly use B-tree indexes for data retrieval, while compiler Implementation, implementations usually use hash tables to look up Identifier (computer languages), identifiers.

Binary Search Tree
In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a Rooted tree, rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree. The time complexity of operations on the binary search tree is Time complexity#Linear time, linear with respect to the height of the tree. Binary search trees allow Binary search algorithm, binary search for fast lookup, addition, and removal of data items. Since the nodes in a BST are laid out so that each comparison skips about half of the remaining tree, the lookup performance is proportional to that of binary logarithm. BSTs were devised in the 1960s for the problem of efficient storage of labeled data and are attributed to Conway Berners-Lee and David_Wheeler_(computer_scientist), David Wheeler. The performance of a binary search tree is dependent on the order of insertion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

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 ...

GNU Lesser General Public License
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MI ...

GNOME
A gnome () is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, including those of modern fantasy literature. They are typically depicted as small humanoids who live underground. Gnome characteristics are reinterpreted to suit various storytellers and artists. Paracelsus's gnome is recognized to have derived from the German miners' legend about or , the "metallurgical or mineralogical demon", according to Georg Agricola (1530), also called (literal Latinization of ''Bergmännlein'', "mountain manikin") by Agriocola in a later work (1549), and described by other names such as (sing. ; Latinization of German ). Agricola recorded that, according to the legends of that profession, these mining spirits acted as miming and laughing pranksters who sometimes threw pebbles at miners, but could also reward them by depositing a rich vein of silver ore. Paracelsus also called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uptane
Uptane is a Linux Foundation / Joint Development Foundation hosted software framework designed to ensure that valid, current software updates are installed in adversarial environments. It establishes a process of checks and balances on these electronic control units (ECUs) that can ensure the authenticity of incoming software updates. Uptane is designed for "compromise-resilience," or to limit the impact of a compromised repository, an insider attack, a leaked signing key, or similar attacks. It can be incorporated into most existing software update technologies, but offers particular support for over-the-air programming or OTA programming strategies originating from The Update Framework. History Uptane was developed by a team of engineers at New York University Tandon School of Engineering in Brooklyn, NY, the University of Michigan Transportation Research Institute in Ann Arbor, MI, and the Southwest Research Institute in San Antonio, TX. It was developed as open source softwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
