Airbnb
Airbnb, Inc. ( ), based in San Francisco, California, operates an online marketplace focused on short-term homestays and experiences. The company acts as a broker and charges a commission from each booking. The company was founded in 2008 by Brian Chesky, Nathan Blecharczyk, and Joe Gebbia. Airbnb is a shortened version of its original name, AirBedandBreakfast.com. The company has been the subject of criticism for lack of regulations and enabling increases in home rents. History After moving to San Francisco in October 2007, roommates and former schoolmates Brian Chesky and Joe Gebbia came up with the idea of putting an air mattress in their living room and turning it into a bed and breakfast. In February 2008, Nathan Blecharczyk, Chesky's former roommate, joined as the Chief Technology Officer and the third co-founder of the new venture, which they named AirBed & Breakfast. They put together a website that offered short-term living quarters and breakfast for those who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyft
Lyft, Inc. offers mobility as a service, ride-hailing, vehicles for hire, motorized scooters, a bicycle-sharing system, rental cars, and food delivery in the United States and select cities in Canada. Lyft sets fares, which vary using a dynamic pricing model based on local supply and demand at the time of the booking and are quoted to the customer in advance, and receives a commission from each booking. Lyft is the second-largest ridesharing company in the United States after Uber. History Lyft was launched in the summer of 2012 by computer programmers Logan Green and John Zimmer as a service of Zimride, a long-distance intercity carpooling company focused on college transport that they founded in 2007 after Green shared rides from the University of California, Santa Barbara campus to visit his girlfriend in Los Angeles and was seeking an easier way to share rides. In May 2013, the company changed its name from Zimride to Lyft. Later that year, Lyft sold the orig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semantic Layer
A semantic layer is a business representation of corporate data that helps end users access data autonomously using common business terms managed through Business semantics management. A semantic layer maps complex data into familiar business terms such as product, customer, or revenue to offer a unified, consolidated view of data across the organization. By using common business terms, rather than data language, to access, manipulate, and organize information, a semantic layer simplifies the complexity of business data. Business terms are stored as objects in a semantic layer, which are accessed through business views. The semantic layer enables business users to have a common "look and feel" when accessing and analyzing data stored in relational databases and OLAP cubes. This is claimed to be core business intelligence (BI) technology that frees users from IT while ensuring correct results. Business Views is a multi-tier system that is designed to enable companies to build compre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache ECharts
The Apache () are a group of culturally related Native American tribes in the Southwestern United States, which include the Chiricahua, Jicarilla, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon and Nednhi or Carrizaleño and Janero), Salinero, Plains (Kataka or Semat or " Kiowa-Apache") and Western Apache ( Aravaipa, Pinaleño, Coyotero, Tonto). Distant cousins of the Apache are the Navajo, with whom they share the Southern Athabaskan languages. There are Apache communities in Oklahoma and Texas, and reservations in Arizona and New Mexico. Apache people have moved throughout the United States and elsewhere, including urban centers. The Apache Nations are politically autonomous, speak several different languages, and have distinct cultures. Historically, the Apache homelands have consisted of high mountains, sheltered and watered valleys, deep canyons, deserts, and the southern Great Plains, including areas in what is now Eastern Arizona, Norther ...

OAuth
OAuth (short for "Open Authorization") is an open standard for access delegation, commonly used as a way for internet users to grant websites or applications access to their information on other websites but without giving them the passwords. This mechanism is used by companies such as Amazon, Google, Facebook, Microsoft, and Twitter to permit the users to share information about their accounts with third-party applications or websites. Generally, OAuth provides clients a "secure delegated access" to server resources on behalf of a resource owner. It specifies a process for resource owners to authorize third-party access to their server resources without providing credentials. Designed specifically to work with Hypertext Transfer Protocol (HTTP), OAuth essentially allows access tokens to be issued to third-party clients by an authorization server, with the approval of the resource owner. The third party then uses the access token to access the protected resources hosted by the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LDAP
The Lightweight Directory Access Protocol (LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number. LDAP is specified in a series of Internet Engineering Task Force (IETF) Standard Track publications called Request for Comments (RFCs), using the description language ASN.1. The latest specification is Version 3, published aRFC 4511ref name="gracion Gracion.com. Retrieved on 2013-07-17. (a road map to t ...

OpenID
OpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites (known as relying parties, or RP) using a third-party identity provider (IDP) service, eliminating the need for webmasters to provide their own ''ad hoc'' login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each. Users create accounts by selecting an OpenID identity provider, and then use those accounts to sign on to any website that accepts OpenID authentication. Several large organizations either issue or accept OpenIDs on their websites. The OpenID standard provides a framework for the communication that must take place between the identity provider and the OpenID acceptor (the " relying party"). An extension to the standard (the OpenID Attribute Exchange) facilitates the transfer of user attributes, such as name and gen ...

Dashboard (business)
In business computer information systems, a dashboard is a type of graphical user interface which often provides at-a-glance views of key performance indicators (KPIs) relevant to a particular objective or business process. In other usage, "dashboard" is another name for "progress report" or "report" and considered a form of data visualization. In providing this overview, business owners can save time and improve their decision making by utilizing dashboards. The “dashboard” is often accessible by a web browser and is usually linked to regularly updating data sources. Well known dashboards include Google Analytics dashboards, used on 55% of all websites, which show activity on a website; such as visits, entry pages, bounce rate and traffic sources. The COVID-19 pandemic of 2020 brought other dashboards to the fore, with the Johns Hopkins coronavirus tracker and the UK government coronavirus tracker being good examples. The term dashboard originates from the automobile da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apache Software Foundation
The Apache Software Foundation (ASF) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support a number of open source software projects. The ASF was formed from a group of developers of the Apache HTTP Server, and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License and is a non-copyleft form of free and open-source software (FOSS). The Apache projects are characterized by a collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers who receive the software freely, to re-distribute it under nonfree terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy, implying tha ...

Apache Incubator
Apache Incubator is the gateway for open-source projects intended to become fully fledged Apache Software Foundation projects. The Incubator project was created in October 2002 to provide an entry path to the Apache Software Foundation for projects and codebases wishing to become part of the Foundation's efforts. All code donations from external organizations and existing external projects wishing to move to Apache must enter through the Incubator. The Apache Incubator project serves on the one hand as a temporary container project until the incubating project is accepted and becomes a top-level project of the Apache Software Foundation or becomes subproject of a proper project such as the Jakarta Project or Apache XML The Apache XML project is part of the Apache Software Foundation and focuses on XML-related projects. It consists of several sub projects: Active sub projects * Xerces: An XML parser for Java, C++ and Perl *Xalan: An XSLT stylesheet processor for .... On the o ...

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ran ...
