KDE3
K Desktop Environment 3 is the third series of releases of the K Desktop Environment (after that called ''KDE Software Compilation''). There are six major releases in this series. After the release of KDE 4, version 3.5 was forked into the Trinity Desktop Environment. K Desktop Environment 3.0 K Desktop Environment 3.0 introduced better support for restricted usage, a feature demanded by certain environments such as kiosks, Internet cafes and enterprise deployments, which disallows the user from having full access to all capabilities of a piece of software. To address these needs, KDE 3.0 included a new lockdown framework, essentially a permissions-based system for altering application configuration options that supplements the standard UNIX permissions system. The KDE panel and the desktop manager were modified to employ this system, but other major desktop components, such as Konqueror and the Control Center, had to wait for subsequent releases.

Qt (framework)
Qt (pronounced "cute") is cross-platform software for creating graphical user interfaces as well as cross-platform applications that run on various software and hardware platforms such as Linux, Windows, macOS, Android or embedded systems with little or no change in the underlying codebase while still being a native application with native capabilities and speed. Qt is currently being developed by The Qt Company, a publicly listed company, and the Qt Project under open-source governance, involving individual developers and organizations working to advance Qt. Qt is available under both commercial licenses and open-source GPL 2.0, GPL 3.0, and LGPL 3.0 licenses. Purposes and abilities Qt is used for developing graphical user interfaces (GUIs) and multi-platform applications that run on all major desktop platforms and most mobile or embedded platforms. Most GUI programs created with Qt have a native-looking interface, in which case Qt is classified as a ''widget toolkit''. No ...

Trinity Desktop Environment
The Trinity Desktop Environment (TDE) is a complete software desktop environment designed for Linux and Unix-like operating systems, intended for computer users preferring a traditional desktop model, and is free/libre software. Born as a fork of KDE 3.5 back in 2010, it was originally created by Timothy Pearson, who had coordinated Kubuntu remixes featuring KDE 3.5 after Kubuntu switched to KDE Plasma 4. TDE is now a fully independent project with its own personality and development team, available for various Linux distros, BSD and DilOS. It is currently led by Slávek Banko. TDE releases aims to provide a stable and highly customizable desktop, continuing bug fixes, additional features, and compatibility with recent hardware.

VCard
vCard, also known as VCF (Virtual Contact File), is a file format standard for electronic business cards. vCards can be attached to e-mail messages, sent via Multimedia Messaging Service (MMS), on the World Wide Web, instant messaging, NFC or through QR code. They can contain name and address information, phone numbers, e-mail addresses, URLs, logos, photographs, and audio clips. vCard is used as data interchange format in smartphone contacts, personal digital assistants (PDAs), personal information managers (PIMs) and customer relationship management (CRMs). To accomplish these data interchange applications, other "vCard variants" have been used and proposed as "variant standards", each for its specific niche: XML representation, JSON representation, or web pages. An unofficial vCard Plus format makes use of a URL to a customized landing page with all the basic information along with a profile photo, geographic location, and other fields. This can also be saved as a conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tab (GUI)
In interface design, a tab is a graphical user interface object that allows multiple documents or panels to be contained within a single window, using tabs as a navigational widget for switching between sets of documents. It is an interface style most commonly associated with web browsers, web applications, text editors, and preference panes, with window managers, especially tiling window managers, being lesser known examples. Tabs are modeled after traditional card tabs inserted in paper files or card indexes (in keeping with the desktop metaphor). Tabs may appear in a horizontal bar or as a vertical list, of which the former takes typically less screen space whereas the latter can show more items at once while still having space for individual titles. Horizontal tabs may have multiple rows. Tabs may be organizable by changing their order through drag and drop or creating a separate window from an existing tab. Implementations may support range-selecting multiple tabs fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KOrganizer
Kontact is a personal information manager and groupware software suite developed by KDE. It supports calendars, contacts, notes, to-do lists, news, and email. It offers a number of inter-changeable graphical UIs (KMail, KAddressBook, Akregator, etc.) all built on top of a common core. Differences between "Kontact" and "KDE PIM" Technically speaking, ''Kontact'' only refers to a small umbrella application that unifies different stand-alone applications under one user interface. ''KDE PIM'' refers to a work group within the larger KDE project that develops the individual applications in a coordinated way. In popular terms, however, ''Kontact'' often refers to the whole set of ''KDE PIM'' applications. These days many popular Linux distributions such as Kubuntu hide the individual applications and only place ''Kontact'' prominently.

Microsoft Exchange Server
Microsoft Exchange Server is a mail server and calendaring server developed by Microsoft. It runs exclusively on Windows Server operating systems. The first version was called Exchange Server 4.0, to position it as the successor to the related Microsoft Mail 3.5. Exchange initially used the X.400 directory service but switched to Active Directory later. Until version 5.0, it came bundled with an email client called Microsoft Exchange Client. This was discontinued in favor of Microsoft Outlook. Exchange Server primarily uses a proprietary protocol called MAPI to talk to email clients, but subsequently added support for POP3, IMAP, and EAS. The standard SMTP protocol is used to communicate to other Internet mail servers. Exchange Server is licensed both as on-premises software and software as a service (SaaS). In the on-premises form, customers purchase client access licenses (CALs); as SaaS, Microsoft charges a monthly service fee instead. History Microsoft had sold a numbe ...

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 ...

Computer Icon
In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or recently voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code. Icons as parts of the graphical user interface of the computer system, in conjunction with windows, menus and a pointing device (mouse), belong to the much ...
