EGroupware
EGroupware is free open-source groupware collaboration software intended for businesses from small to enterprise. Its primary functions allow users to manage contacts, appointments, projects and to-do lists. The project releases its software under the terms of GNU General Public License (GPL). It is used either via its native web-interface, making access platform-independent, or by using different supported groupware clients, such as Kontact, Novell Evolution, or Microsoft Outlook. It can also be used by mobile phone or PDA via SyncML. It has translations for more than 25 languages, including right-to-left language support. History EGroupware is the most current manifestation of a chain of projects. The original project was called webdistro. In 2000 development on the project phpgroupware began, which was based on webdistro; and in 2003 the EGroupware fork was born. EGroupware has a very pronounced community character compared with its predecessors. There is an EGroup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPLv2
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or copyleft, ''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 Lesser General Public License, GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD licenses, BSD, MIT License, MIT, and Apache License, Apache. Historically, the GPL license family has been one of the most pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BigBlueButton
BigBlueButton is a virtual classroom software program designed for online education. It is accessed through Learning Management Systems, providing engagement tools and analytics which enable educators to interact with their students remotely. BigBlueButton is open source, except for some versions of its database software. History The project was started at Carleton University in 2007 by the Technology Innovation Management program. The first version, initially referred to as the Blindside project, was written by Richard Alam under the supervision of Tony Bailetti. BigBlueButton is an affiliate member of the Open Source Initiative. The BigBlueButton name derives from the idea that starting a web conference should be as simple as "pressing a (metaphorical) big blue button". In 2009, Richard Alam, Denis Zgonjanin, and Fred Dixon uploaded the BigBlueButton source code to Google Code and formed Blindside Networks, a company pursuing the traditional open source business model o ...

Video Conference
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types. Video systems vary in display resolution, aspect ratio, refresh rate, color capabilities, and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcasts, magnetic tape, optical discs, computer files, and network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mechanical video scanners, such as the Nipkow disk, were patented as early as 1884, however, it took several deca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Chat
Online chat is any direct text-, audio- or video-based (webcams), one-on-one or one-to-many ( group) chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs or other online games. Online chat includes web-based applications that allow communication – often directly addressed, but anonymous between users in a multi-user environment. Web conferencing is a more specific online service, that is often sold as a service, hosted on a web server controlled by the vendor. Online chat may address point-to-point communications as well as multicast communications from one sender to multiple receivers and voice and video chat, or may be a feature of a web conferencing service. ''Online chat'' in a narrower sense is any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CalDAV
Calendaring Extensions to WebDAV, or CalDAV, is an Internet standard allowing a client to access and manage calendar data along with the ability to schedule meetings with users on the same or on remote servers. It lets multiple users in different locations share, search and synchronize calendar data. It extends the WebDAV (HTTP-based protocol for data manipulation) specification and uses the iCalendar format for the calendar data. The access protocol is defined by . Extensions to CalDAV for scheduling are standardized as . The protocol is used by many important open-source applications. History The ''CalDAV'' specification was first published in 2003 as an Internet Draft submitted to the Internet Engineering Task Force (IETF) by Lisa Dusseault. In March 2007, the ''CalDAV'' specification was finished and published by the IETF as RFC 4791, authored by Cyrus Daboo (Apple), Bernard Desruissaux (Oracle), and Lisa Dusseault (CommerceNet). ''CalDAV'' is designed for implementation b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sieve
A sieve (), fine mesh strainer, or sift is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Sieving Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. Depending upon the types of particles to be separated, sieves with different types of holes are used. Sieves are also used to separate stones from sand. Sieving plays an important role in food ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dovecot (software)
Dovecot is an open-source IMAP and POP3 server for Unix-like operating systems, written primarily with security in mind. Timo Sirainen originated Dovecot and first released it in July 2002. Dovecot developers primarily aim to produce a lightweight, fast and easy-to-set-up open-source email server. The primary purpose of Dovecot is to act as a mail storage server. The mail is delivered to the server using some mail delivery agent (MDA) and is stored for later access with an email client (mail user agent, or MUA). Dovecot can also act as mail proxy server, forwarding connection to another mail server, or act as a lightweight MUA in order to retrieve and manipulate mail on remote server for e.g. mail migration. According to thOpen Email Survey as of 2020, Dovecot has an installed base of at least 2.9million IMAP servers, and has a global market share of 76.9% of all IMAP servers. The results of the same survey in 2019 gave figures of 2.6million and 76.2%, respectively. Features ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mail Server
Within the Internet email system, a message transfer agent (MTA), mail transfer agent, or mail relay is software that transfers electronic mail messages from one computer to another using the Simple Mail Transfer Protocol. In some contexts, the alternative names mail server, mail exchanger, or MX host are used to describe an MTA. Messages exchanged across networks are passed between mail servers, including any attached data files (such as images, multimedia, or documents). These servers often keep mailboxes for email. Access to this email by end users is typically either by webmail or an email client. Operation A message transfer agent receives mail from either another MTA, a mail submission agent (MSA), or a mail user agent (MUA). The transmission details are specified by the Simple Mail Transfer Protocol (SMTP). When a recipient mailbox of a message is not hosted locally, the message is relayed, that is, forwarded to another MTA. Every time an MTA receives an email message, ...

File Sharing
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include removable media, centralized servers on computer networks, Internet-based hyperlinked documents, and the use of distributed peer-to-peer networking. File sharing technologies, such as BitTorrent, are integral to modern media piracy, as well as the sharing of scientific data and other free content. History Files were first exchanged on removable media. Computers were able to access remote files using filesystem mounting, bulletin board systems (1978), Usenet (1979), and FTP servers (1970's). Internet Relay Chat (1988) and Hotline (1997) enabled users to communicate remotely through chat and to exchange files. The mp3 encoding, which was standardized in 1991 and substantially reduced the size of audio files, grew to widespread use ...

Web Application Firewall
A web application firewall (WAF) is a specific form of application firewall that filters, monitors, and blocks HTTP traffic to and from a web service. By inspecting HTTP traffic, it can prevent attacks exploiting a web application's known vulnerabilities, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration. Most of the major financial institutions utilize WAFs to help in the mitigation of web application "zero-day" vulnerabilities, as well as hard-to-patch bugs or weaknesses through custom attack signature strings. History Dedicated web application firewalls entered the market in the late 1990s during a time when web server attacks were becoming more prevalent. Early WAF products, from Kavado and Gilian technologies, were available, trying to solve the increasing amount of attacks on web applications in the late 1990s. In 2002, the open-source project ModSecurity was formed in order to make WAF technology more accessible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
