Kernel.org
kernel.org on the World Wide Web is the main distribution point of source code for the Linux kernel, which is the base of the Linux operating system. The website and related infrastructure, which is operated by the Linux Kernel Organization, host the repositories that make all versions of the kernel's source code available to all users. The main purpose of kernel.org is to host repositories used by Linux kernel developers and maintainers of various Linux distributions. Additionally, it hosts various other projects or their mirrors, including the Linux Documentation Project (LDP) and CPAN. Since August 2014, kernel.org provides additional security by mandating two-factor authentication for commits performed to hosted Git repositories that contain source code of the Linux kernel, with support for both soft tokens and hard tokens. 2011 security breach On 28 August 2011, developers at kernel.org realized that there had been a major security breach. Intruders had gained r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Kernel
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free software, free replacement for Unix. Since the late 1990s, it has been included in many Linux distributions, operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android (operating system), Android which is used in many mobile and embedded devices. Most of the kernel code is written in C (programming language), C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly language, assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a Modular programming, modular design such that modules can be inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-source License
Open-source licenses are software licenses that allow content to be used, modified, and shared. They facilitate free and open-source software (FOSS) development. Intellectual property (IP) laws restrict the modification and sharing of creative works. Free and open-source licenses use these existing legal structures for an inverse purpose. They Grant (law), grant the recipient the rights to use the software, examine the source code, modify it, and distribute the modifications. These criteria are outlined in the Open Source Definition. After 1980, the United States began to treat software as a literary work covered by copyright law. Richard Stallman founded the free software movement in response to the rise of proprietary software. The term "open source" was used by the Open Source Initiative (OSI), founded by free software developers Bruce Perens and Eric S. Raymond. "Open source" emphasizes the strengths of the Open-source software development, open development model rather tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-factor Authentication
Multi-factor authentication (MFA; two-factor authentication, or 2FA) is an electronic authentication method in which a user is granted access to a website or Application software, application only after successfully presenting two or more distinct types of evidence (or Authentication#Authentication factors, factors) to an authentication mechanism. MFA protects personal data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password. Usage of MFA has increased in recent years. Security issues which can cause the bypass of MFA are #Fatigue attack, fatigue attacks, phishing and SIM swap scam, SIM swapping. Accounts with MFA enabled are significantly less likely to be compromised. Authentication factors Authentication takes place when someone tries to log into a computer resource (such as a computer network, device, or application). The resource requires ...

Linux Kernel Mailing List
The Linux kernel mailing list (LKML) is the main electronic mailing list for Linux kernel development, where the majority of the announcements, discussions, debates, and flame wars over the kernel take place. Many other mailing lists exist to discuss the different subsystems and ports of the Linux kernel, but LKML is the principal communication channel among Linux kernel developers. It is a very high-volume list, usually receiving about 1,000 messages each day, most of which are kernel code patches. Linux utilizes a workflow governed by LKML, which is the "bazaar" where kernel development takes place. In his book ''Linux Kernel Development'', Robert Love notes: The LKML functions as the central place where Linux developers around the world share patches, argue about implementation details, and discuss other issues. The official releases of the Linux kernel are indicated by an email to LKML. New features are discussed and most code is posted to the list before any action is t ...

Ars Technica
''Ars Technica'' is a website covering news and opinions in technology, science, politics, and society, created by Ken Fisher and Jon Stokes in 1998. It publishes news, reviews, and guides on issues such as computer hardware and software, science, technology policy, and video games. ''Ars Technica'' was privately owned until May 2008, when it was sold to Condé Nast Digital, the online division of Condé Nast Publications. Condé Nast purchased the site, along with two others, for $25 million and added it to the company's ''Wired'' Digital group, which also includes '' Wired'' and, formerly, Reddit. The staff mostly works from home and has offices in Boston, Chicago, London, New York City, and San Francisco. The operations of ''Ars Technica'' are funded primarily by advertising, and it has offered a paid subscription service since 2001. History Ken Fisher, who serves as the website's current editor-in-chief, and Jon Stokes created ''Ars Technica'' in 1998. Its purpose was t ...

Linus Torvalds
Linus Benedict Torvalds ( , ; born 28 December 1969) is a Finnish software engineer who is the creator and lead developer of the Linux kernel. He also created the distributed version control system Git. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award and the 2018 IEEE Masaru Ibuka Consumer Electronics Award.

Linux Foundation
The Linux Foundation (LF) is a non-profit organization established in 2000 to support Linux development and open-source software projects. Background The Linux Foundation started as Open Source Development Labs in 2000 to standardize and promote the open-source operating system kernel Linux. It merged with Free Standards Group in 2007. The foundation has since evolved to promote open-source projects beyond the Linux OS as a "foundation of foundations" that hosts a variety of projects spanning topics such as cloud computing, cloud, networking, blockchain, and hardware. The foundation also hosts annual educational events among the Linux community, including the Linux Kernel Developers Summit and the Open Source Summit. Projects , the total economic value of the development costs of Linux Foundation Collaborative Projects was estimated at $5 billion. Community stewardship For the Linux kernel community, the Linux Foundation hosts its IT infrastructure and organizes #Confe ...

Hard Token
Multi-factor authentication (MFA; two-factor authentication, or 2FA) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more distinct types of evidence (or factors) to an authentication mechanism.

Soft Token
A software token (a.k.a. ''soft token'') is a piece of a two-factor authentication security device that may be used to authorize the use of computer services. Software tokens are stored on a general-purpose electronic device such as a desktop computer, laptop, PDA, or mobile phone and can be duplicated. (Contrast hardware tokens, where the credentials are stored on a dedicated hardware device and therefore cannot be duplicated — absent physical invasion of the device) Because software tokens are something one does not physically possess, they are exposed to unique threats based on duplication of the underlying cryptographic material - for example, computer viruses and software attacks. Both hardware and software tokens are vulnerable to bot-based man-in-the-middle attacks, or to simple phishing attacks in which the one-time password provided by the token is solicited, and then supplied to the genuine website in a timely manner. Software tokens do have benefits: there is no phys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Git (software)
Git () is a distributed version control software system, system that tracks versions of computer file, files. It is often used to control source code by Programmer, programmers who are software development, developing software collaboratively. Design goals of Git include speed, data integrity, and support for Distributed computing, distributed, non-linear workflows — thousands of parallel Branching (version control), branches running on different computers. "So I'm writing some scripts to try to track things a whole lot faster." As with most other distributed version control systems, and unlike most client–server systems, Git maintains a local copy of the entire Repository (version control), repository, also known as "repo", with history and version-tracking abilities, independent of Computer network, network access or a central Server (computing), server. A repository is stored on each computer in a standard directory (computing), directory with additional, Hidden f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commit (data Management)
In computer science and data management, a commit is a behavior that marks the end of a transaction and provides Atomicity (database systems), Atomicity, Consistency (database systems), Consistency, Isolation (database systems), Isolation, and Durability (database systems), Durability (ACID) in transactions. The submission records are stored in the submission Log file, log for recovery and consistency in case of failure. In terms of transactions, the opposite of committing is giving up tentative changes to the transaction, which is rolled back. Due to the rise of distributed computing and the need to ensure data consistency across multiple systems, commit protocols have been evolving since their emergence in the 1970s. The main developments include the Two-phase commit protocol, Two-Phase Commit (2PC) first proposed by Jim Gray (computer scientist), Jim Gray, which is the fundamental core of distributed transaction management. Subsequently, the Three-phase commit protocol, Three- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Documentation Project
The Linux Documentation Project (LDP) is a dormant all-volunteer project that maintains a large collection of GNU and Linux-related documentation and publishes the collection online. It began as a way for hackers to share their documentation with each other and with their users, and for users to share documentation with each other. Its documents tend to be oriented towards experienced users such as professional system administrators, but it also contains tutorials for beginners. History The LDP originally began as an FTP site in 1992, but it went on the World Wide Web at MetaLab in 1993. It is believed to have been the first Linux related website ever. Today, the LDP serves over 475 documents contributed by even more authors. About a dozen of them are book length, and most of those are available in print from major technical publishers including O'Reilly. In 2008, LDP started ''The LDP Wiki''; the wiki has since gone offline with the last entry dating to 2016. the most r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
