Time-based Release Schedule
Release early, release often (also known as ship early, ship often, or time-based releases, and sometimes abbreviated RERO) is a software development philosophy that emphasizes the importance of early and frequent releases in creating a tight feedback loop between developers and testers or users, contrary to a feature-based release strategy. Advocates argue that this allows the software development to progress faster, enables the user to help define what the software will become, better conforms to the users' requirements for the software, and ultimately results in higher quality software. The development philosophy attempts to eliminate the risk of creating software that no one will use. This philosophy was popularized by Eric S. Raymond in his 1997 essay ''The Cathedral and the Bazaar'', where Raymond stated "Release early. Release often. And listen to your customers". This philosophy was originally applied to the development of the Linux kernel and other open-source software, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Software Development Philosophies
This is a list of approaches, styles, methodologies, and philosophies in software development and engineering. It also contains programming paradigms, software development methodologies, software development processes, and single practices, principles, and laws. Some of the mentioned methods are more relevant to a specific field than another, such as automotive or aerospace. The trend towards agile methods in software engineering is noticeable, however the need for improved studies on the subject is also paramount. Also note that some of the methods listed might be newer ''or'' older ''or'' still in use ''or'' out-dated, and the research on software design methods is not new and on-going. Software development methodologies, guidelines, strategies Large-scale programming styles * Behavior-driven development * Design-driven development * Domain-driven design * Secure by design * Test-driven development ** Acceptance test-driven development ** Continuous test-driven developm ...

Eric S
The given name Eric, Erich, Erikk, Erik, Erick, Eirik, or Eiríkur is derived from the Old Norse name ''Eiríkr'' (or ''Eríkr'' in Old East Norse due to monophthongization). The first element, ''ei-'' may be derived from the older Proto-Norse ''* aina(z)'', meaning "one, alone, unique", ''as in the form'' ''Æ∆inrikr'' explicitly, but it could also be from ''* aiwa(z)'' "everlasting, eternity", as in the Gothic form '' Euric''. The second element ''- ríkr'' stems either from Proto-Germanic ''* ríks'' "king, ruler" (cf. Gothic ''reiks'') or the therefrom derived ''* ríkijaz'' "kingly, powerful, rich, prince"; from the common Proto-Indo-European root * h₃rḗǵs. The name is thus usually taken to mean "sole ruler, autocrat" or "eternal ruler, ever powerful". ''Eric'' used in the sense of a proper noun meaning "one ruler" may be the origin of '' Eriksgata'', and if so it would have meant "one ruler's journey". The tour was the medieval Swedish king's journey, when newly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Cathedral And The Bazaar
''The Cathedral and the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary'' (abbreviated ''CatB'') is an essay, and later a book, by Eric S. Raymond on software engineering methods, based on his observations of the Linux kernel development process and his experiences managing an open source project, fetchmail. It examines the struggle between top-down and bottom-up design. The essay was first presented by Raymond at the Linux Kongress on May 27, 1997, in Würzburg, Germany, and was published as the second chapter of the sametitled book in 1999. The illustration on the cover of the book is a 1913 painting by Lyubov Popova titled ''Composition with Figures'' and belongs to the collection of the State Tretyakov Gallery. The book was released under the Open Publication License v2.0 in 1999. Central thesis The software essay contrasts two different free software development models: * The ''cathedral'' model, in which source code is available with each ...

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 Software
Open-source software (OSS) is Software, computer software that is released under a Open-source license, license in which the copyright holder grants users the rights to use, study, change, and Software distribution, distribute the software and its source code to anyone and for any purpose. Open-source software may be developed in a collaborative, public manner. Open-source software is a prominent example of open collaboration, meaning any capable user is able to online collaboration, participate online in development, making the number of possible contributors indefinite. The ability to examine the code facilitates public trust in the software. Open-source software development can bring in diverse perspectives beyond those of a single company. A 2024 estimate of the value of open-source software to firms is $8.8 trillion, as firms would need to spend 3.5 times the amount they currently do without the use of open source software. Open-source code can be used for studying and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprietary Software
Proprietary software is computer software, software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms. Proprietary software is a subset of non-free software, a term defined in contrast to free and open-source software; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software. Types Origin Until the late 1960s, computers—especially large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold. Service and all software available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
User Experience
User experience (UX) is how a user interacts with and experiences a product, system or service. It includes a person's perceptions of utility, ease of use, and efficiency. Improving user experience is important to most companies, designers, and creators when creating and refining products because negative user experience can diminish the use of the product and, therefore, any desired positive impacts. Conversely, designing toward profitability as a main objective often conflicts with ethical user experience objectives and even causes harm. User experience is subjective. However, the attributes that make up the user experience are objective. Definitions According to Nielsen Norman Group, 'user experience' includes all the aspects of the interaction between the end-user with the company, its services, and its products. The international standard on ''ergonomics of human-system interaction'', ISO 9241, defines user experience as a "user’s perceptions and responses that ...

Worse Is Better
''Worse is better'' (also called the ''New Jersey style'') is a term conceived by Richard P. Gabriel in a 1989 essay to describe the dynamics of software acceptance. It refers to the argument that software quality does not necessarily increase with functionality: that there is a point where less functionality ("worse") is a preferable option ("better") in terms of practicality and usability. Software that is limited, but simple to use, may be more appealing to the user and market than the reverse. As to the oxymoronic title, Gabriel calls it a caricature, declaring the style bad in comparison with "The Right Thing". However he also states that "it has better survival characteristics than the-right-thing" development style and is superior to the "MIT Approach" with which he contrasted it. The essay was included into the 1994 book '' The UNIX-HATERS Handbook'', and has been referred to as the origin of the notion of a conceptual split between developers on the east and west coast ...

Programming Paradigm
A programming paradigm is a relatively high-level way to conceptualize and structure the implementation of a computer program. A programming language can be classified as supporting one or more paradigms. Paradigms are separated along and described by different dimensions of programming. Some paradigms are about implications of the execution model, such as allowing Side effect (computer science), side effects, or whether the sequence of operations is defined by the execution model. Other paradigms are about the way code is organized, such as grouping into units that include both state and behavior. Yet others are about Syntax (programming languages), syntax and Formal grammar, grammar. Some common programming paradigms include (shown in hierarchical relationship): * imperative programming, Imperative code directly controls Control flow, execution flow and state change, explicit statements that change a program state ** procedural programming, procedural organized as function (c ...

Software Development Process
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a specific organization. For example, many specific software development processe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Software Development
Agile software development is an umbrella term for approaches to software development, developing software that reflect the values and principles agreed upon by ''The Agile Alliance'', a group of 17 software practitioners, in 2001. As documented in their ''Manifesto for Agile Software Development'' the practitioners value: * Individuals and interactions over processes and tools * Working software over comprehensive documentation * Customer collaboration over contract negotiation * Responding to change over following a plan The practitioners cite inspiration from new practices at the time including extreme programming, Scrum (software development), scrum, dynamic systems development method, adaptive software development and being sympathetic to the need for an alternative to documentation driven, heavyweight software development processes. Many software development practices emerged from the agile mindset. These agile-based practices, sometimes called ''Agile'' (with a capital ...

Minimum Viable Product
A minimum viable product (MVP) is a version of a product with just enough features to be usable by early customers who can then provide feedback for future product development. A focus on releasing an MVP means that developers potentially avoid lengthy and (possibly) unnecessary work. Instead, they iterate on working versions and respond to feedback, challenging and validating assumptions about a product's requirements. The term was coined and defined in 2001 by Frank Robinson and then popularized by Steve Blank and Eric Ries.W. S. Junk,The Dynamic Balance Between Cost, Schedule, Features, and Quality in Software Development Projects, Computer Science Dept., University of Idaho, SEPM-001, April 2000. It may also involve carrying out market analysis beforehand. The MVP is analogous to experimentation in the scientific method applied in the context of validating business hypotheses. It is utilized so that prospective entrepreneurs would know whether a given business idea would ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
