Postcardware
Shareware is a type of proprietary software that is initially shared by the owner for trial use at little or no cost. Often the software has limited functionality or incomplete documentation until the user sends payment to the software developer. Shareware is often offered as a download from a website. Shareware differs from freeware, which is fully-featured software distributed at no cost to the user but without source code being made available; and free and open-source software, in which the source code is freely available for anyone to inspect and alter. There are many types of shareware and, while they may not require an initial up-front payment, many are intended to generate revenue in one way or another. Some limit use to personal non-commercial purposes only, with purchase of a license required for use in a business enterprise. The software itself may be time-limited, or it may remind the user that payment would be appreciated. Types of shareware Trialware Trialware o ...

Postcard
A postcard or post card is a piece of thick paper or thin cardboard, typically rectangular, intended for writing and mailing without an envelope. Non-rectangular shapes may also be used but are rare. In some places, one can send a postcard for a lower fee than a letter. Stamp collectors distinguish between postcards (which require a postage stamp) and postal cards (which have the postage pre-printed on them). While a postcard is usually printed and sold by a private company, individual or organization, a postal card is issued by the relevant postal authority (often with pre-printed postage). Production of postcards blossomed in the late 19th and early 20th centuries. As an easy and quick way for individuals to communicate, they became extremely popular. The study and collecting of postcards is termed ''deltiology'' (from Greek , small writing tablet, and the also Greek ''-logy'', the study of). History 1840 to 1864 Cards with messages have been sporadically created ... [...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] |
Screencasting
A screencast is a digital recording of computer screen output, also known as a video screen capture or a screen recording, often containing audio narration. The term ''screencast'' compares with the related term ''screenshot''; whereas screenshot generates a single picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, that can be enhanced with audio narration and captions. Etymology In 2004, columnist Jon Udell invited readers of his blog to propose names for the emerging genre. Udell selected the term "screencast", which was proposed by both Joseph McDonald and Deeje Cooley. The terms "screencast," "screencam" and "screen recording" are often used interchangeably, due to the market influence of ScreenCam as a screencasting product of the early 1990s. ScreenCam, however, is a federal trademark in the United States, whereas screencast is not trademarked and has established use in publications as part of ...

Roguelike
Roguelike (or rogue-like) is a style of role-playing game traditionally characterized by a dungeon crawl through procedurally generated levels, turn-based gameplay, grid-based movement, and permanent death of the player character. Most roguelikes are based on a high fantasy narrative, reflecting the influence of tabletop role-playing games such as ''Dungeons & Dragons''. Though '' Beneath Apple Manor'' predates it, the 1980 game '' Rogue'', which is an ASCII based game that runs in terminal or terminal emulator, is considered the forerunner and the namesake of the genre, with derivative games mirroring ''Rogue''s Text-based game, character- or Sprite (computer graphics), sprite-based graphics. These games were popularized among college students and computer programmers of the 1980s and 1990s, leading to hundreds of variants. Some of the better-known variants include ''Hack (video game), Hack'', ''NetHack'', ''Ancient Domains of Mystery'', ''Moria (1983 video game), Moria' ...

Aaron Giles
According to the Old Testament of the Bible, Aaron ( or ) was an Israelite prophet, a high priest, and the elder brother of Moses. Information about Aaron comes exclusively from religious texts, such as the Hebrew Bible, the New Testament ( Luke, Acts, and Hebrews), and the Quran. The Hebrew Bible relates that, unlike Moses, who grew up in the Egyptian royal court, Aaron and his elder sister Miriam remained with their kinsmen in the northeastern region of the Nile Delta. When Moses first confronted the Egyptian king about the enslavement of the Israelites, Aaron served as his brother's spokesman to the Pharaoh. Part of the Law given to Moses at Sinai granted Aaron the priesthood for himself and his male descendants, and he became the first High Priest of the Israelites. Levitical priests or ''kohanim'' are traditionally believed and halakhically required to be of direct patrilineal descent from Aaron. According to the Book of Numbers, Aaron died at 123 years of age, on M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beerware
Beerware is a tongue-in-cheek software license with permissive terms, which grants the right to do anything with the source code, assuming the license notice is preserved. Description Should the user of the code consider the software useful, they are encouraged to buy the author a beer "in return" if they ever meet. The Humanitarian-FOSS project at Trinity College recognized the ''"version 42"'' beerware license variant as an extremely permissive "copyright only" and GPL-compatible license. According to the Free Software Foundation the license would be classified as an "informal" free, non-copyleft and GPL-compatible license, however more detailed licenses are recommended. Poul-Henning Kamp states preference of his Beerware license to other licenses, such as BSD and GPL, the latter of which he has described as a "joke". The full text of Kamp's license is: See also * 0BSD a public domain equivalent license used by Toybox and explicitly allowed for Android * An ...

Email
Electronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving Digital media, digital messages using electronics, electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence ''wikt:e-#Etymology 2, e- + mail''). Email is a ubiquitous and very widely used communication medium; in current use, an email address is often treated as a basic and necessary part of many processes in business, commerce, government, education, entertainment, and other spheres of daily life in most countries. Email operates across computer networks, primarily the Internet access, Internet, and also local area networks. Today's email systems are based on a store-and-forward model. Email Server (computing), servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect, ty ...

Dialog Box
In computing, a dialog box (also simply dialog) is a graphical control element in the form of a small window that communicates information to the user and prompts them for a response. Dialog boxes are classified as " modal" or "modeless", depending on whether they block interaction with the software that initiated the dialog. The type of dialog box displayed is dependent upon the desired user interaction. The simplest type of dialog box is the alert, which displays a message and may require an acknowledgment that the message has been read, usually by clicking "OK", or a decision as to whether or not an action should proceed, by clicking "OK" or "Cancel". Alerts are also used to display a "termination notice"—sometimes requesting confirmation that the notice has been read—in the event of either an intentional closing or unintentional closing (" crash") of an application or the operating system. ( E.g., " Gedit has encountered an error and must close.") Although t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Watermarking
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data.H.T. Sencar, M. Ramkumar and A.N. Akansu: ''Data Hiding Fundamentals and Applications: Content Security in Digital Multimedia''. Academic Press, San Diego, CA, USA, 2004. It is typically used to identify ownership of the copyright of such a signal. Digital watermarking is the process of hiding digital information in a carrier signal; the hidden information should,Ingemar J. Cox: ''Digital watermarking and steganography''. Morgan Kaufmann, Burlington, MA, USA, 2008 but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional physical watermarks, digital watermarks are often only perceptible under certain conditions, e.g. af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modal Window
In user interface design, a modal window is a graphical control element subordinate to an application's main window. A modal window creates a mode that disables user interaction with the main window but keeps it visible, with the modal window as a child window in front of it. Users ''must'' interact with the modal window before they can return to the parent window. This avoids interrupting the workflow Workflow is a generic term for orchestrated and repeatable patterns of activity, enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a seque ... on the main window. Modal windows are sometimes called heavy windows or modal dialogs because they often display a dialog box. User interfaces typically use modal windows to command user awareness and to display emergency states, though interaction designers argue they are ineffective for that use. Modal windows are prone to mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crippleware
Crippleware is computer software or hardware that has been intentionally designed to have some of its features disabled or not working to its full capability until payment of some kind is rendered. In software, crippleware means that "vital features of the program such as printing or the ability to save files are disabled until the user purchases a registration key". While crippleware allows consumers to see the software before they buy, they are unable to test its complete functionality because of the disabled functions. Hardware crippleware is "a hardware device that has not been designed to its full capability". The functionality of the hardware device is limited to encourage consumers to pay for a more expensive upgraded version. Usually the hardware device considered to be crippleware can be upgraded to better or its full potential by way of a trivial change, such as removing a jumper wire. The manufacturer would most likely release the crippleware as a low-end or economy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
