Alpine (e-mail Client)
Alpine is a free software email client developed at the University of Washington. Alpine is a rewrite of the Pine Message System that adds support for Unicode and other features. Alpine is meant to be suitable for both inexperienced email users and the most demanding of power users. Alpine can be learned by exploration and the use of context-sensitive help. The user interface can be customized. Features Alpine shares many common features of console applications, like a rich set of shortcut keys, using a keyboard instead of a mouse for all navigation and operations. In fact, all operations in Alpine have corresponding shortcut keys. Unlike other console applications targeting developers and experienced users, which often require users to edit a configuration file, Alpine lets users change most configuration options within the software. This makes alpine one of the most easy to learn console-based email clients. Alpine supports IMAP, POP, SMTP, NNTP and LDAP protocols natively. ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Maildir
The Maildir e-mail format is a common way of storing email messages in which each message is stored in a separate file with a unique name, and each mail folder is a file system directory. The local file system handles file locking as messages are added, moved and deleted. A major design goal of Maildir is to eliminate the need for program code to handle file locking and unlocking. __TOC__ Specifications A Maildir directory (often named Maildir) usually has three subdirectories named tmp, new, and cur. The tmp subdirectory temporarily stores e-mail messages that are in the process of being delivered. This subdirectory may also store other kinds of temporary files. The new subdirectory stores messages that have been delivered, but have not yet been seen by any mail application. The cur subdirectory stores messages that have already been seen by mail applications. Maildir++ Sam Varshavchik, the author of the Courier Mail Server and other software, wrote an extension to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Debian
Debian (), also known as Debian GNU/Linux, is a Linux distribution composed of free and open-source software, developed by the community-supported Debian Project, which was established by Ian Murdock on August 16, 1993. The first version of Debian (0.01) was released on September 15, 1993, and its first stable version (1.1) was released on June 17, 1996. The Debian Stable branch is the most popular edition for personal computers and servers. Debian is also the basis for many other distributions, most notably Ubuntu. Debian is one of the oldest operating systems based on the Linux kernel. The project is coordinated over the Internet by a team of volunteers guided by the Debian Project Leader and three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines. New distributions are updated continually, and the next candidate is released after a time-based freeze. Since its founding, Debian has been developed openly ...

Fedora Project
The Fedora Project is an independent project to co-ordinate the development of Fedora Linux, a Linux-based operating system, operating with the vision of "''a world where everyone benefits from free and open source software built by inclusive, welcoming, and open-minded communities.''" The project's mission statement is to create "''an innovative platform for hardware, clouds, and containers that enables software developers and community members to build tailored solutions for their users''". The project also oversees Extra Packages for Enterprise Linux, a special interest group which maintains the eponymous packages. The project was founded in 2003 as a result of a merger between the Red Hat Linux (RHL) and Fedora Linux projects. It is sponsored by Red Hat (an IBM subsidiary) primarily, but its employees make up only 35% of project contributors, and most of the over 2,000 contributors are unaffiliated members of the community. History The Fedora Project was founded in Novemb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upstream (software Development)
In software development, when software has been forked or uses a chain of libraries/ dependencies, upstream refers to an issue that occurs in software farther up the chain. It is the direction that is toward the original authors or maintainers of software. It is usually used in the context of a version, a bug, or a patch. Upstream development allows other distributions to benefit from it when they pick up the future release or merge recent (or all) upstream patches. Likewise, the original authors (maintaining upstream) can benefit from contributions that originate from custom distributions, if their users send patches upstream. The term also pertains to bugs; responsibility for a bug is said to lie upstream when it is not caused through the distribution's porting, non-upstream modification or integration efforts. Examples * A patch ''sent upstream'' is offered to the original authors or maintainers of the software. If accepted, the authors or maintainers will include the pat ...

Unix-like
A Unix-like (sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell. Although there are general philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux and BSD. These systems are often used on servers, as well as on personal computers and other devices. Many popular applications, such as the Apache web server and the Bash shell, are also designed to be used on Unix-like systems. One of the key features of Unix-like systems is their ability to support multiple users and processes simultaneously. This allows users to run multipl ...

Google Groups
Google Groups is a service from Google that provides discussion groups for people sharing common interests. The Groups service also provides a gateway to Usenet newsgroups via a shared user interface. Google Groups became operational in February 2001, following Google's acquisition of Deja's Usenet archive. Deja News had been operational since March 1995. Google Groups allows any user to freely conduct and access threaded discussions, via either a web interface or e-mail. There are at least two kinds of discussion group. The first kind are forums specific to Google Groups, which act more like mailing lists. The second kind are Usenet groups, accessible by NNTP, for which Google Groups acts as gateway and unofficial archive. The Google Groups archive of Usenet newsgroup postings dates back to 1981. Through the Google Groups user interface, users can read and post to Usenet groups. In addition to accessing Google and Usenet groups, registered users can also set up mailing list ar ...

Usenet Newsgroup
A Usenet newsgroup is a repository usually within the Usenet system, for messages posted from users in different locations using the Internet. They are discussion groups and are not devoted to publishing news. Newsgroups are technically distinct from, but functionally similar to, discussion forums on the World Wide Web. Newsreader software is used to read the content of newsgroups. Before the adoption of the World Wide Web, Usenet newsgroups were among the most popular Internet services, and have retained their noncommercial nature in contrast to the increasingly ad-laden web. In recent years, this form of open discussion on the Internet has lost considerable ground to individually-operated browser-accessible forums and big media social networks such as Facebook and Twitter. Communication is facilitated by the Network News Transfer Protocol (NNTP) which allows connection to Usenet servers and data transfer over the internet. Similar to another early (yet still used) protocol S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Control Key
In computing, a Control key is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, ); similar to the Shift key, the Control key rarely performs any function when pressed by itself. The Control key is located on or near the bottom left side of most keyboards (in accordance with the international standard ISO/IEC 9995-2), with many featuring an additional one at the bottom right. On keyboards that use English abbreviations for key labeling, it is usually labeled (rarely, or is seen). Abbreviations in the language of the keyboard layout also are in use, e.g., the German keyboard layout uses as required by the German standard DIN 2137:2012-06. Also, there is a standardized keyboard symbol (to be used when Latin lettering is not preferred), given in ISO/IEC 9995-7 as symbol 26, and in ISO 7000 "Graphical symbols for use on equipment" as symbol ISO-7000-2028. This symbol is encoded in Unicode as U+2388 (⎈). His ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S/MIME
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and signing of MIME data. S/MIME is on an IETF standards track and defined in a number of documents, most importantly . It was originally developed by RSA Data Security and the original specification used the IETF MIME specification with the de facto industry standard PKCS#7 secure message format. Change control to S/MIME has since been vested in the IETF and the specification is now layered on Cryptographic Message Syntax (CMS), an IETF specification that is identical in most respects with PKCS #7. S/MIME functionality is built into the majority of modern email software and interoperates between them. Since it is built on CMS, MIME can also hold an advanced digital signature. Function S/MIME provides the following cryptographic security services for electronic messaging applications: * Authentication * Message integrity * Non-repudiation of origin (using digital signatures) * Privacy ...

Pico (text Editor)
Pico (Pine composer) is a text editor for Unix and Unix-like computer systems. It is integrated with the Pine and Alpine email clients, which were initially designed by the Office of Computing and Communications at the University of Washington. From the Pine FAQ: "Pine's message composition editor is also available as a separate stand-alone program, called PICO. PICO is a very simple and easy-to-use text editor offering paragraph justification, cut/paste, and a spelling checker...". Pico does not support working with several files simultaneously and cannot perform a find and replace across multiple files. It also cannot copy partial text from one file to another (though it is possible to read text into the editor from a whole file in its working directory). Pico does support search and replace operations. By comparison, some popular Unix text editors such as vi and Emacs provide a wider range of features than Pico; including regular expression search and replace, and working wit ...
