NetKernel
NetKernel is a British software company and software platform by the same name that is used for High Performance Computing, Enterprise Application Integration, and Energy Efficient Computation. It allows developers to cleanly separate code from architecture. It can be used as an application server, embedded in a Java container or employed as a cloud computing platform. As a platform, it is an implementation of the resource-oriented computing (ROC) abstraction. ROC is a ''logical'' computing model that resides on top of but is completely isolated from the ''physical'' realm of code and objects. In ROC, information and services are identified by logical addresses which are resolved to physical endpoints for the duration of a request and then released. Logical indirect addressing results in flexible systems that can be changed while the system is in operation. In NetKernel, the boundary between the logical and physical layers is intermediated by an operation-system caliber microkernel ...

Resource-oriented Computing
Resource-oriented computing (ROC) is a simple abstract computing model used for describing, designing, and implementing software and software systems. The fundamental idea behind ROC is derived from the World Wide Web, Unix, and other sources as well as original research conducted at HP Laboratories. Fundamental concepts Resource-oriented computing describes an abstract computing model. The fundamental idea is that sets of information known as resources are treated as abstracts; that is, a resource is a Platonic concept of the information that is the subject of a computation process. Resources are identified by logical addresses (typically a URI) and processing is defined using compositions and sequences of resource requests. At the physical level, a ROC system processes resource-representations, executes transformations and, in so doing, computes new resources. In this respect ROC is no different from any other computational model – computation is performed to collate and reve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HP Laboratories
HP Labs is the exploratory and advanced research group for HP Inc. HP Labs' headquarters is in Palo Alto, California and the group has research and development facilities in Bristol, UK. The development of programmable desktop calculators, inkjet printing, and 3D graphics are credited to HP Labs researchers. HP Labs was established on March 3, 1966, by Hewlett-Packard founders Bill Hewlett and David Packard, seeking to create an organization not bound by day-to-day business concerns. The labs have downsized dramatically; in August 2007, HP executives drastically diminished the number of projects, down from 150 to 30. As of 2018, HP Labs has just over 200 researchers, compared to earlier staffing levels of 500 researchers. With Hewlett Packard Enterprise being spun off from Hewlett-Packard on November 1, 2015, and the remaining company being renamed to HP Inc., the research lab also spun off Hewlett Packard Labs to Hewlett Packard Enterprise and HP Labs was kept for HP Inc. ...

Monolithic Kernel
A monolithic kernel is an operating system software architecture, architecture with the entire operating system running in kernel space. The monolithic model differs from other architectures such as the microkernel in that it alone defines a high-level virtual interface over computer hardware. A set of primitives or system calls implement all operating system services such as Process (computing), process management, Concurrency (computer science), concurrency, and memory management. Device drivers can be added to the kernel as loadable kernel modules. Examples *Most BSD kernels **FreeBSD **OpenBSD **NetBSD *Linux kernel **Android (operating system), Android *Other Unix/Unix-like kernels **AIX **Oracle Solaris *MS-DOS **Windows 9x *OpenVMS *Palm OS (version ≤ 5.0) Loadable modules Modular operating systems such as OS-9 and most modern monolithic-kernel operating systems such as OpenVMS, Linux kernel, Linux, FreeBSD, NetBSD, DragonFly BSD, Oracle Solaris, Solaris, and AIX can d ...

Cross-platform Software
Within computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Linux, macOS and Microsoft Windows. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, ArkUI-X, Kivy, Qt, GTK, Flutter, NativeScript, Xamarin, Apache Cordova, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jolie (programming Language)
Jolie (Java Orchestration Language Interpreter Engine) is an open-source programming language for developing distributed applications based on microservices. In the programming paradigm proposed with Jolie, each program is a service that can communicate with other programs by sending and receiving messages over a network. Jolie supports an abstraction layer that allows services to communicate using different mediums, ranging from TCP/IP sockets to local in-memory communications between processes. Jolie is currently supported by an interpreter implemented in the Java language, which can be run in multiple operating systems including Linux-based operating systems, OS X, and Windows. The language comes with formal semantics, meaning that the execution of Jolie programs is mathematically defined. For this reason, Jolie is used in research for the investigation of language-based techniques for the development of distributed systems, and it is also used for teaching at some universit ...

Representational State Transfer
REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web. REST defines a set of constraints for how the architecture of a distributed, Internet-scale hypermedia system, such as the Web, should behave. The REST architectural style emphasises uniform API, interfaces, independent deployment of Software component, components, the scalability of interactions between them, and creating a Multitier architecture, layered architecture to promote caching to reduce user-perceived latency (engineering), latency, enforce computer security, security, and encapsulate legacy systems. REST has been employed throughout the software industry to create stateless protocol, stateless, reliable, web application, web-based applications. An application that adheres to the #Architectural constraints, REST architectural constraints may be informally described as ''RESTful'', althoug ...

Groovy (programming Language)
Apache Groovy is a Java-syntax-compatible object-oriented programming language for the Java platform. It is both a static and dynamic language with features similar to those of Python, Ruby, and Smalltalk. It can be used as both a programming language and a scripting language for the Java Platform, is compiled to Java virtual machine (JVM) bytecode, and interoperates seamlessly with other Java code and libraries. Groovy uses a curly-bracket syntax similar to Java's. Groovy supports closures, multiline strings, and expressions embedded in strings. Much of Groovy's power lies in its AST transformations, triggered through annotations. Groovy 1.0 was released on January 2, 2007, and Groovy 2.0 in July, 2012. Since version 2, Groovy can be compiled statically, offering type inference and performance near that of Java. Groovy 2.4 was the last major release under Pivotal Software's sponsorship which ended in March 2015. Groovy has since changed its governance structure to a Proj ...

Java Message Service
The Jakarta Messaging API (formerly Java Message Service or JMS API) is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems. Jakarta Messaging is a part of Jakarta EE and was originally defined by a specification developed at Sun Microsystems before being guided by the Java Community Process. General idea of messaging Messaging is a form of '' loosely coupled'' distributed communication, where in this context the term 'communication' can be understood as an exchange of messages between software components. Message-oriented technologies attempt to relax ''tightly coupled'' communication (such as TCP network sockets, CORBA or RMI) by the introduction of an intermediary component. This approach allows software components to communicate with each other indirectly. Benefit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
XSLT
XSLT (Extensible Stylesheet Language Transformations) is a language originally designed for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text, or XSL Formatting Objects. These formats can be subsequently converted to formats such as PDF, PostScript, and PNG. Support for JSON and plain-text transformation was added in later updates to the XSLT 1.0 specification. XSLT 3.0 implementations support Java, .NET, C/C++, Python, PHP and NodeJS. An XSLT 3.0 JavaScript library can also be hosted within the web browser. Modern web browsers also include native support for XSLT 1.0. The XSLT document transformation specifies how to transform an XML document into new document (usually XML, but other formats, such as plain text are supported). Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, such as relational database tables or geographical inform ...

Functional Program
In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program. In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local identifiers), passed as arguments, and returned from other functions, just as any other data type can. This allows programs to be written in a declarative and composable style, where small functions are combined in a modular manner. Functional programming is sometimes treated as synonymous with purely functional programming, a subset of functional programming that treats all functions as deterministic mathematical functions, or pure functions. When a pure function is called with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
