Pixelfed
Pixelfed is a free and open-source image sharing social network service. It is decentralized, therefore user data is not stored on a central server, unlike other platforms. Pixelfed uses the ActivityPub protocol which allows users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Using this protocol makes Pixelfed a part of the Fediverse. The network is made up of several independent sites that communicate with one another, which is roughly comparable to e-mail providers. The parties involved do not all have to be registered with the same provider, but can still communicate with each other. Thus, users are able to sign up on any server and follow others on the other instances. Much like Mastodon, Pixelfed implements chronological timelines without content manipulation algorithms. It also aims to be privacy-focused with no third party analytics or tracking. Pixelfed optionally organizes its media by hashtags, geo-tagging and ...

Fediverse
The fediverse (a portmanteau of "federation" and "universe") is an ensemble of Federation (information technology), federated (i.e. interconnected) servers that are used for web publishing (i.e. social networking, microblogging, blogging, or websites) and file hosting, but which, while independently hosted, can communicate with each other. On different servers (technically Instance (computer science), instances), users can create so-called identities. These identities are able to communicate over the boundaries of the instances because the software running on the servers supports one or more communication protocols that follow an open standard. As an identity on the fediverse, users are able to post text and other media, or to follow posts by other identities. In some cases, users can show or Data sharing, share data (video, audio, text, and other files) publicly or to a selected group of identities, and allow other identities to edit other users' data (such as a calendar or an addr ...

Friendica
Friendica (formerly Friendika, originally Mistpark) is a free and open-source software distributed social network. It forms one part of the Fediverse, an interconnected and decentralized network of independently operated servers. Features Friendica users can connect with others via their own Friendica server, but may also fully integrate contacts from other platforms including Twitter, Diaspora, Pump.io, StatusNet and more recently ActivityPub (Mastodon, Pleroma, Pixelfed...) into their 'newsfeed'. In addition to these two way connections, users can also use Friendica as a publishing platform to post content to WordPress, Tumblr and Libertree. Posting to Google+ was also supported until its shutdown. In addition, e-mail contacts and RSS feeds can be integrated. Because users are distributed across many servers, their "addresses" consist of a username, the "@" symbol, and the domain name of the Friendica instance in the same manner email addresses are formed. Most of the function ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ActivityPub
ActivityPub is an open, decentralized social networking protocol based on Pump.io's ActivityPump protocol. It provides a client/server API for creating, updating, and deleting content, as well as a federated server-to-server API for delivering notifications and content. Project status ActivityPub is a standard for the Internet in the Social Web Networking Group of the World Wide Web Consortium (W3C). The standard was co-authored by Evan Prodromou, creator of StatusNet (now known as GNU social). At an earlier stage, the name of the protocol was "ActivityPump", but it was felt that ActivityPub better indicated the cross-publishing purpose of the protocol. It learned from the experiences with the older standard called OStatus. It is the most widely supported standard (by some margin) in the Fediverse. In January 2018, the World Wide Web Consortium (W3C) published the ActivityPub standard as a Recommendation. The W3C Social Community Group organizes a yearly free conferen ...

Instagram
Instagram is a photo and video sharing social networking service owned by American company Meta Platforms. The app allows users to upload media that can be edited with filters and organized by hashtags and geographical tagging. Posts can be shared publicly or with preapproved followers. Users can browse other users' content by tag and location, view trending content, like photos, and follow other users to add their content to a personal feed. Instagram was originally distinguished by allowing content to be framed only in a square (1:1) aspect ratio of 640 pixels to match the display width of the iPhone at the time. In 2015, this restriction was eased with an increase to 1080 pixels. It also added messaging features, the ability to include multiple images or videos in a single post, and a Stories feature—similar to its main competitor Snapchat—which allowed users to post their content to a sequential feed, with each post accessible to others for 24 hours. As of Janu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gigabyte
The gigabyte () is a multiple of the unit byte for digital information. The prefix ''giga'' means 109 in the International System of Units (SI). Therefore, one gigabyte is one billion bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science (especially data science), engineering, business, and many areas of computing, including storage capacities of hard drives, solid state drives, and tapes, as well as data transmission speeds. However, the term is also used in some fields of computer science and information technology to denote (10243 or 230) bytes, particularly for sizes of RAM. Thus, prior to 1998, some usage of ''gigabyte'' has been ambiguous. To resolve this difficulty, IEC 80000-13 clarifies that a ''gigabyte'' (GB) is 109 bytes and specifies the term ''gibibyte'' (GiB) to denote 230 bytes. These differences are still readily seen for example, when a 400 GB drive's capacity is displayed by Microsoft Windows as 372 G ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Two-factor Authentication
Multi-factor authentication (MFA; encompassing two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something only the user knows), possession (something only the user has), and inherence (something only the user is). MFA protects user data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password. A ''third-party authenticator'' (TPA) app enables two-factor authentication, usually by showing a randomly generated and frequently changing code to use for authentication. Factors Authentication takes place when someone tries to log into a computer resource (such as a network, device, or application). The resource requires the u ...

TOTP (algorithm)
Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) that uses the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard . TOTP is the cornerstone of Initiative for Open Authentication (OATH), and is used in a number of two-factor authentication (2FA) systems. History Through the collaboration of several OATH members, a TOTP draft was developed in order to create an industry-backed standard. It complements the event-based one-time standard HOTP, and it offers end user organizations and enterprises more choice in selecting technologies that best fit their application requirements and security guidelines. In 2008, OATH submitted a draft version of the specification to the IETF. This version incorporates all the feedback and commentary that the authors received from the technical community based on the prior v ...

1Password
1Password is a password manager developed by AgileBits Inc. It supports multiple platforms such as iOS, Android, Windows, Linux, and macOS. It provides a place for users to store various passwords, software licenses, and other sensitive information in a virtual vault that is locked with a PBKDF2-guarded master password. By default, the user’s encrypted vault is hosted on AgileBits’ servers for a monthly fee. The company is based in Toronto, Canada. Password file syncing 1Password can be configured through 1Password.com, a paid subscription-based server sync service maintained by the developers. Local Wi-Fi and iCloud sync were only available on iOS and macOS in previous versions. In 2017, the Travel Mode feature was introduced for subscribers of 1Password.com, which enables omission of password entries not tagged as safe for travel from the local storage on a particular device, reducing the impact of being obliged by officials to unlock access at country border crossings.

Friending And Following
Friending is the act of adding someone to a list of "friends" on a social networking service. The notion does not necessarily involve the concept of friendship. It is also distinct from the idea of a " fan"—as employed on the WWW sites of businesses, bands, artists, and others—since it is more than a one-way relationship. A "fan" only receives things. A "friend" can communicate back to the person friending. The act of "friending" someone usually grants that person special privileges (on the service) with respect to oneself. On Facebook, for example, one's "friends" have the privilege of viewing and posting to one's "timeline". Following is a similar concept on other social network services, such as Twitter and Instagram, where a person (''follower'') chooses to add content from a person or page to his or her newsfeed. Unlike friending, following is not necessarily mutual, and a person can ''unfollow'' (stop following) or block another user at any time without affecting th ...

Authy
Twilio () is an American company based in San Francisco, California, which provides programmable communication tools for making and receiving phone calls, sending and receiving text messages, and performing other communication functions using its web service APIs. History Twilio was founded in 2008 by Jeff Lawson, Evan Cooke, and John Wolthuis and was originally based in both Seattle, Washington, and San Francisco, California. Twilio's first major press coverage, in November 2008, was the result of an application built by Jeff Lawson to rickroll people, which investor Dave McClure used on TechCrunch founder and editor Michael Arrington as a prank. A few days later, on November 20, 2008, the company launched Twilio Voice, an API to make and receive phone calls completely hosted in the cloud. Twilio's text messaging API was released in February 2010, and SMS shortcodes were released in public beta in July 2011. Twilio raised approximately $103 million in venture capital growth ...
