Camera

A camera is an optical instrument for recording images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

Functional description

A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

Camera+

Camera+ is an app for Apple's iOS mobile operating system developed by tap tap tap. The app serves as an alternative to the standard iOS camera app, primarily adding basic and advanced editing tools (including special effects and lighting filters), an image stabilizer, and integrated sharing with Facebook, Flickr, and Twitter.

Camera+ has received generally positive reception; PC Advisor gave the app 4-and-a-half stars out of 5 and declared it a "must-have" app for iPhone photographers, praising its advanced editing functionality for allowing users to "[make] poor snaps into great photographs that will wow your friends", making the built-in camera app feel like a pinhole in comparison.Wired gave the app a 9 out of 10, describing it as a "secret weapon" for photographers, and stating that it contained so much functionality that it was "too easy to get lost in the deeply layered menus or forget where you found that killer function the other day." In May 2012, Apple revealed that Camera+ was the 10th most popular paid app of all-time among iPhone users.

Generic top-level domain

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.

The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.

Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.

Bitcoin

Bitcoin is a digital asset and a payment system invented by Satoshi Nakamoto, who published the invention in 2008 and released it as open-source software in 2009. The system is peer-to-peer; users can transact directly without an intermediary. Transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. The ledger uses bitcoin as its unit of account. The system works without a central repository or single administrator, which has led the U.S. Treasury to categorize bitcoin as a decentralized virtual currency. Bitcoin is often called the first cryptocurrency, although prior systems existed. Bitcoin is more correctly described as the first decentralized digital currency. It is the largest of its kind in terms of total market value.

Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.

Bodoland Territorial Council

The Bodoland Territorial Council (BTC) is a territorial privilege established in India according to the Memorandum of Settlement of February 10, 2003. BTC came into existence immediately after surrender of Bodo Liberation Tigers Force (BLTF) cadres. The BLTF laid down their weapons on December 6, 2003 under the leadership of Hagrama Mohilary and Hagrama was sworn in as the Chief Executive Member (CEM) on December 7, 2003. The BTC has 46 executive members each looking after a specific area of control called somisthi. The area under the BTC jurisdiction is called the Bodoland Territorial Area District (BTAD). BTC constitutes 70% of marginalised Tribal groups like Bodos, Rabhas, Garos, etc. who are against the hegemony of Assam government. The region falls within the geographical map of least developed region in India. The agro-based economy is the only source of livelihood of the people. Industrialisation and other employment opportunities are hardly to been.

The BTAD is to consist of four contiguous districts — Kokrajhar, Baksa, Udalguri and Chirang — carved out of seven existing districts — Kokrajhar, Bongaigaon, Barpeta, Nalbari, Kamrup, Darrang and Sonitpur — an area of 27,100 km² (35% of Assam). That the BTAD is created under the sixth schedule of the Constitution of India has been opposed by some organizations.
