RAR (file Format)
RAR is a proprietary archive file format that supports data compression, error correction and file spanning. It was developed in 1993 by Russian software engineer Eugene Roshal and the software is licensed by ''win.rar GmbH''. The name ''RAR'' stands for ''Roshal Archive''. File format The filename extensions used by RAR are .rar for the data volume set and .rev for the recovery volume set. Previous versions of RAR split large archives into several smaller files, creating a "multi-volume archive". Numbers were used in the file extensions of the smaller files to keep them in the proper sequence. The first file used the extension .rar, then .r00 for the second, and then .r01, .r02, etc. RAR compression applications and libraries (including GUI based WinRAR application for Windows, console rar utility for different OSes and others) are proprietary software, to which Alexander L. Roshal, the elder brother of Eugene Roshal, owns the copyright. Version 3 of RAR is based on Lempel- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WinRAR
WinRAR is a trialware file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. It can create and view archives in RAR or ZIP file formats, and unpack numerous archive file formats. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. WinRAR supports creating encrypted, multi-part and self-extracting archives. WinRAR is a Windows-only program. An Android application called "RAR for Android" is also available. Related programs include the command-line utilities "RAR" and "UNRAR" and versions for macOS, Linux, FreeBSD, Windows CE, and MS-DOS. Evolution WinRAR and the RAR file format have evolved over time. Support for the archive format RAR5, using the same RAR file extension as earlier versions, was added in version 5.0; the older RAR file format has since been referred to as RAR4. WinRAR versions before 5.0 do not support RAR5 archives; only older versions of WinRAR run on Windows ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelyabinsk
Chelyabinsk ( rus, Челя́бинск, p=tɕɪˈlʲæbʲɪnsk, a=Ru-Chelyabinsk.ogg; ba, Силәбе, ''Siläbe'') is the administrative center and largest city of Chelyabinsk Oblast, Russia. It is the seventh-largest city in Russia, with a population of over 1.1 million people, and the second-largest city in the Ural Federal District, after Yekaterinburg. Chelyabinsk runs along the Miass River, and is just east of the Ural Mountains. The area of Chelyabinsk contained the ancient settlement of Arkaim, which belonged to the Sintashta culture. In 1736, a fortress by the name of Chelyaba was founded on the site of a Bashkir village. Chelyabinsk was granted town status by 1787. Chelyabinsk began to grow rapidly by the early 20th century as a result of the construction of railway links from the Russian core to Siberia, including the Trans-Siberian Railway. Its population reached 70,000 by 1917. Under the Soviet Union, Chelyabinsk became a major industrial centre durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software Engineering
Software engineering is a systematic engineering approach to software development. A software engineer is a person who applies the principles of software engineering to design, develop, maintain, test, and evaluate computer software. The term '' programmer'' is sometimes used as a synonym, but may also lack connotations of engineering education or skills. Engineering techniques are used to inform the software development process which involves the definition, implementation, assessment, measurement, management, change, and improvement of the software life cycle process itself. It heavily uses software configuration management which is about systematically controlling changes to the configuration, and maintaining the integrity and traceability of the configuration and code throughout the system life cycle. Modern processes use software versioning. History Beginning in the 1960s, software engineering was seen as its own type of engineering. Additionally, the development of ...

File Format
A file format is a Computer standard, standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary format, proprietary or open format, free. Some file formats are designed for very particular types of data: Portable Network Graphics, PNG files, for example, store Raster graphics, bitmapped Graphics file format, images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container format (digital), container for different types of multimedia including any combination of sound, audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various Character encoding, character encoding schemes. Some file formats, such as HTML, sca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Archiver
A file archiver is a computer program that combines a number of files together into one archive file, or a series of archive files, for easier transportation or storage. File archivers may employ lossless data compression in their archive formats to reduce the size of the archive. Basic archivers just take a list of files and concatenate their contents sequentially into archives. The archive files need to store metadata, at least the names and lengths of the original files, if proper reconstruction is possible. More advanced archivers store additional metadata, such as the original timestamps, file attributes or access control lists. The process of making an archive file is called ''archiving'' or ''packing''. Reconstructing the original files from the archive is termed ''unarchiving'', ''unpacking'' or ''extracting''. History An early archiver was the Multics command ''archive'', descended from the CTSS command of the same name, which was a basic archiver and performed no com ...

FAR Manager
Far Manager (short for ''File and ARchive Manager'') is an orthodox file manager for Microsoft Windows and is a clone of Norton Commander. Far Manager uses the Win32 console and has a keyboard-oriented user interface (although limited mouse operation, including drag-and-drop, is possible). Far Manager was created by Eugene Roshal, and has been under development by the ''Far Group'' since 2000. The project's Unicode branches (2.0 and 3.0) are open-source (under the BSD-3-Clause license). All branches are available as 32- and 64-bit builds. Far Manager is often viewed as a very customizable file manager and text editor, and a free alternative to Total Commander. Features Far Manager features an internal viewer and editor, customizable user menus, tree views, file search, compare, integrated help, and a task switcher for its tools. Its standard functionality can be expanded with macros (which allow scripting) and plugins. Far Manager's default interface combines two file panels ...

People From Chelyabinsk
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of p ...
