Threshold Pledge System
The threshold pledge or fund and release system is a way of making a fundraising pledge as a group of individuals, often involving charitable goals or financing the provision of a public good. An amount of money is set as the goal or ''threshold'' to reach for the specified purpose and interested individuals will pitch in, but the money at first either remains with the pledgers or is held in escrow. When the threshold is reached, the pledges are called in (or transferred from the escrow fund) and a contract is formed so that the collective good is supplied; a variant is that the money is collected when the good is actually delivered. If the threshold is not reached by a certain date (or perhaps if no contract is ever signed, etc.), the pledges are either never collected or, if held in escrow, are simply returned to the pledgers. In economics, this type of model is known as an assurance contract. This system is most often applied to creative works, both for financing new produ ...

Fundraising
Fundraising or fund-raising is the process of seeking and gathering voluntary financial contributions by engaging individuals, businesses, charitable foundations, or governmental agencies. Although fundraising typically refers to efforts to gather money for non-profit organizations, it is sometimes used to refer to the identification and solicitation of investors or other sources of capital for-profit enterprises. Traditionally, fundraising has consisted mostly of asking for donations through face-to-face fundraising, such as door-knocking. In recent years, though, new forms such as online fundraising or grassroots fundraising have emerged. Organizations Fundraising is a significant way that non-profit organizations may obtain the money for their operations. These operations can involve a very broad array of concerns such as religious or philanthropic groups such as research organizations, public broadcasters, political campaigns and environmental issues.

Not A Number Technologies
Blender is a free and open-source 3D computer graphics software tool set that runs on Windows, macOS, BSD, Haiku, IRIX and Linux. It is used for creating animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, and virtual reality. It is also used in creating video games. Blender was used to produce the Academy Award-winning film '' Flow'' (2024). History Blender was initially developed as an in-house application by the Dutch animation studio NeoGeo (no relation to the video game brand), and was officially launched on January 2, 1994. Version 1.00 was released in January 1995, with the primary author being the company co-owner and software developer Ton Roosendaal. The name ''Blender'' was inspired by a song by the Swiss electronic band Yello, from the album ''Baby'', which NeoGeo used in its showreel. Some design choices and experiences for Blender were carried over from an earlier software application, called Traces, that Roosenda ...

Vanity Press
A vanity press or vanity publisher, sometimes also subsidy publisher, is a book printer that is paid by authors to Self-published, self-publish their books. A vanity press charges fees in advance and does not contribute to the development of the book. It has been described as a scam. However, as the book does get printed, it does not necessarily meet the definition of actual fraud. The term ''vanity press'' is derogatory, so it is not used by the printers. Some self-publishing businesses prefer to market themselves as an independent press, and some authors who are self-publishing through CreateSpace and Amazon Kindle prefer to market themselves as Indie literature, indie authors instead of as self-publishing authors. It is not to be confused with hybrid publishing, where the publisher and author collaborate and ''share'' costs and risks, or with assisted self-publishing, where the authors, sometimes styling themselves as ''authorpreneurs'', pay various contractors and publishin ...

Free Content
Free content, libre content, libre information, or free information is any kind of creative work, such as a work of art, a book, a software program, or any other creative content for which there are very minimal copyright and other legal limitations on usage, modification and distribution. These are works or expressions which can be freely studied, applied, copied and modified by anyone for any purpose including, in some cases, commercial purposes. Free content encompasses all works in the public domain and also those copyrighted works whose licenses honor and uphold the definition of free cultural work. In most countries, the Berne Convention grants copyright holders control over their creations by default. Therefore, copyrighted content must be explicitly declared free by the authors, which is usually accomplished by referencing or including licensing statements from within the work. The right to reuse such a work is granted by the authors in a license known as a free lice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copyright
A copyright is a type of intellectual property that gives its owner the exclusive legal right to copy, distribute, adapt, display, and perform a creative work, usually for a limited time. The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself. A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States and fair dealings doctrine in the United Kingdom. Some jurisdictions require "fixing" copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders. These rights normally include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution. Copyrights can be granted by ...

Cryptographer
Cryptography, or cryptology (from "hidden, secret"; and ''graphein'', "to write", or '' -logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, convertin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copyleft
Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, ''freedoms'' refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, and scientific discoveries, and similar approaches have even been applied to Patentleft, certain patents. Copyleft software licenses are considered ''protective'' or ''reciprocal'' (in contrast with Permissive software license, permissive free software licenses): they require that information necessary for reproducing and modifying the work be made available to recipients of the software program. This information is most commonly in the form of source code files, which usually contain a copy of the license terms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Domain
The public domain (PD) consists of all the creative work to which no Exclusive exclusive intellectual property rights apply. Those rights may have expired, been forfeited, expressly Waiver, waived, or may be inapplicable. Because no one holds the exclusive rights, anyone can legally use or reference those works without permission. As examples, the works of William Shakespeare, Ludwig van Beethoven, Miguel de Cervantes, Zoroaster, Lao Zi, Confucius, Aristotle, L. Frank Baum, Leonardo da Vinci and Georges Méliès are in the public domain either by virtue of their having been created before copyright existed, or by their copyright term having expired. Some works are not covered by a country's copyright laws, and are therefore in the public domain; for example, in the United States, items excluded from copyright include the formulae of Classical mechanics, Newtonian physics and cooking recipes. Other works are actively dedicated by their authors to the public domain (see waiver) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Outside Europe, a number of special territories of EU members also use the euro as their currency. The euro is used by 350 million people in Europe and additionally, over 200 million people worldwide use currencies pegged to the euro. It is the second-largest reserve currency as well as the second-most traded currency in the world after the United Sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...
