Collaborative real-time editor

Collaborative real-time editor
A collaborative editor is a form of collaborative software application that allows several people to edit a computer file using different computers, a practice called collaborative editing. There are two types of collaborative editing: real-time and non-real-time. In real-time collaborative editing (RTCE), users can edit the same file simultaneously, whereas in Non-real-time collaborative editing, the users do not edit the same file at the same time (similar to revision control systems). Collaborative real-time editors generally permit both the above modes of editing in any given instance. History[edit] The first instance of a collaborative real-time editor was demonstrated by Douglas Engelbart in 1968, in The Mother of All Demos. Instant Update was released for Mac OS in 1991 from ON Technology.[1] Later, a version for Microsoft Windows was released as well, allowing real-time collaboration across these two operating systems.

Google Drive Google Drive is a file storage and synchronization service provided by Google, released on April 24, 2012,[4][5] which enables user cloud storage, file sharing and collaborative editing. Rumors about Google Drive began circulating as early as March 2006.[6] Files shared publicly on Google Drive can be searched with web search engines. Google Drive is the home of Google Docs, an office suite of productivity applications, that offer collaborative editing on documents, spreadsheets, presentations, and more. Storage[edit] Google offers all users an initial 15 GB of online storage space, that is shared across three of its most-used services: Google Drive, Gmail, and Google+ Photos[7] (aka Picasa Web Albums).[8] Users can upgrade their free 15 GB account through a paid monthly subscription plan to get additional storage.[8] Documents using Google Docs native formats (including .gdoc, .gslides, and .gsheet) do not count towards this quota.

Google Docs An example of a document in Google Docs Google Docs is a free, web-based office suite offered by Google within its Google Drive service. It was formerly a storage service as well, but has since been replaced by Google Drive.[3] It allows users to create and edit documents online while collaborating with other users live. Google Docs combines the features of Writely and Spreadsheets with a presentation program incorporating technology designed by Tonic Systems. Data storage of files was introduced on January 12, 2010 with 1 GB of free space. History[edit] Writely's beta logo Google Docs originated from two separate products, Writely and Google Spreadsheets. Spreadsheets, launched as Google Labs Spreadsheets on June 6, 2006,[7] originated from the acquisition of the XL2Web product by 2Web Technologies. Writely originally ran on Microsoft ASP.NET technology which uses Microsoft Windows. In February 2007, Google Docs was made available to Google Apps users. Features[edit] File limits[edit]

Getting Things Done The GTD method rests on the idea of moving planned tasks and projects out of the mind by recording them externally and then breaking them into actionable work items. This allows attention to be focused on taking action on tasks, instead of recalling them.[2] First published in 2001, a revised edition of the book was released in 2015 to reflect the changes in information technology during the preceding decade. Themes[edit] Allen first demonstrates stress reduction from the method with the following exercise, centered on a task that has an unclear outcome or whose next action is not defined. Allen calls these sources of stress "open loops", "incompletes", or "stuff".[1]:13 He claims stress can be reduced and productivity increased by putting reminders about everything you are not working on into a trusted system external to your mind.

Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBC, Vevo, Hulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program.[5] Unregistered users can watch videos, and registered users can upload an unlimited number of videos. Videos considered to contain potentially offensive content are available only to registered users affirming themselves to be at least 18 years old. Company history

Twitter History Creation and initial reaction Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group.[15][16] The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass,[17] inspired by Flickr and the five-character length of American SMS short codes. The developers initially considered "10958" as a short code, but later changed it to "40404" for "ease of use and memorability ...we came across the word 'twitter', and it was just perfect. The first Twitter prototype, developed by Dorsey and contractor Florian Weber, was used as an internal service for Odeo employees[20] and the full version was introduced publicly on July 15, 2006.[8] With Twitter, it wasn't clear what it was. Reaction at the conference was highly positive. Growth Leadership

Why I Connect With Strangers on LinkedIn In online and real-world networking, the same principle applies: You never know when you might make a crucial connection. Social networks are like any other social environment: No two have exactly the same standards of acceptable behaviour. For good reasons, most of us would think twice before granting a Facebook friend request from a stranger. And since the workplace tends to have more rigid social standards than other areas of life, people commonly assume that their cache of connections on LinkedIn – the leading internet venue for professional networking – should be similarly exclusive, if not more so. But among my LinkedIn connections are many people I’ve never met offline. Weak Ties Win the Day In 1973, sociologist Mark Granovetter published a classic paper called “The Strength of Weak Ties,” which found that social capital, i.e. Finding Your “Godfather” There is no hard-and-fast way to know which of your weak ties will be the conduit for your next golden opportunity.
