Perkeep
Perkeep (previously Camlistore, Content-Addressable Multi-Layer Indexed Storage) is a set of open-source formats, protocols, and software for modeling, storing, searching, sharing, and synchronizing data. Storage Perkeep's content-addressable storage is based on GPG-signed claims. These claims provide modeling, storing, searching, sharing, and synchronization of data. Perkeep can be thought of as Git for general personal information storage: a user's Perkeep is the main repository. Perkeep is graph-based rather than a working tree in data model terminology. Perkeep can store files like a traditional file system, but it specializes in storing objects such as pictures and videos. Development The Perkeep project is under active development led by Brad Fitzpatrick, a former Google employee (originally as a 20% Project Side project time is a type of employee benefit constituting a guarantee from employers that their employees may work on their personal projects during some part (usual ...

Content-addressable Storage
Content-addressable storage (CAS), also referred to as content-addressed storage or fixed-content storage, is a way to store information so it can be retrieved based on its content, not its name or location. It has been used for high-speed storage and retrieval of fixed content, such as documents stored for compliance with government regulations. Content-addressable storage is similar to content-addressable memory. CAS systems work by passing the content of the file through a cryptographic hash function to generate a unique key, the "content address". The file system's directory stores these addresses and a pointer to the physical storage of the content. Because an attempt to store the same file will generate the same key, CAS systems ensure that the files within them are unique, and because changing the file will result in a new key, CAS systems provide assurance that the file is unchanged. CAS became a significant market during the 2000s, especially after the introduction of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

Go (programming Language)
Go is a statically typed, compiled programming language designed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. It is syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency. It is often referred to as Golang because of its former domain name, golang.org, but its proper name is Go. There are two major implementations: * Google's self-hosting "gc" compiler toolchain, targeting multiple operating systems and WebAssembly. * gofrontend, a frontend to other compilers, with the ''libgo'' library. With GCC the combination is gccgo; with LLVM the combination is gollvm. A third-party source-to-source compiler, GopherJS, compiles Go to JavaScript for front-end web development. History Go was designed at Google in 2007 to improve programming productivity in an era of multicore, networked machines and large codebases. The designers wanted to address criticism of other languages in use at Google, but keep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Store
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. D ...

Apache License 2
The Apache () are a group of culturally related Native Americans in the United States, Native American tribe (Native American), tribes in the Southwestern United States, which include the Chiricahua, Jicarilla Apache, Jicarilla, Lipan Apache people, Lipan, Mescalero, Mimbreño, Ndendahe (Bedonkohe or Mogollon culture, Mogollon and Nednhi or Carrizaleño and Janero), Salinero Apaches, Salinero, Plains Apache, Plains (Kataka or Semat or "Plains Apache, Kiowa-Apache") and Western Apache (San Carlos Apache Indian Reservation, Aravaipa, Pinaleño Mountains, Pinaleño, Fort Apache Indian Reservation, Coyotero, Tonto Apache, Tonto). Distant cousins of the Apache are the Navajo, with whom they share the Southern Athabaskan languages. There are Apache communities in Oklahoma and Texas, and Indian reservation, reservations in Arizona and New Mexico. Apache people have moved throughout the United States and elsewhere, including urban centers. The Apache Nations are politically autonomous, ...

GNU Privacy Guard
GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's PGP cryptographic software suite. The software is compliant with RFC 4880, the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP-compliant systems. GnuPG is part of the GNU Project and received major funding from the German government in 1999. Overview GnuPG is a hybrid-encryption software program because it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient's public key to encrypt a session key which is used only once. This mode of operation is part of the OpenPGP standard and has been part of PGP from its first version. The GnuPG 1.x series uses an integrated cryptographic library, while the GnuPG 2.x series replaces this with Libgcrypt. GnuPG encrypts messages using asymmetric key pairs individually g ...

Git (software)
Git () is a distributed version control system: tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows (thousands of parallel branches running on different systems). "So I'm writing some scripts to try to track things a whole lot faster." Git was originally authored by Linus Torvalds in 2005 for development of the Linux kernel, with other kernel developers contributing to its initial development. Since 2005, Junio Hamano has been the core maintainer. As with most other distributed version control systems, and unlike most client–server systems, every Git directory on every computer is a full-fledged repository with complete history and full version-tracking abilities, independent of network access or a central server. Git is free and open-source software distributed under the GPL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repository (revision Control)
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single server. Some of the metadata that a repository contains includes, among other things, a historical record of changes in the repository, a set of commit objects, and a set of references to commit objects, called ''heads''. The main purpose of a repository is to store a set of files, as well as the history of changes made to those files. Exactly how each version control system handles storing those changes, however, differs greatly. For instance, Subversion in the past relied on a database instance but has since moved to storing its changes directly on the filesystem. These differences in storage tech ...

20% Project
Side project time is a type of employee benefit constituting a guarantee from employers that their employees may work on their personal projects during some part (usually a percentage) of their time at work. Side project time is limited by two stipulations: what the employee works on is the intellectual property of their employer, and if requested, an explanation must be able to be given as to how the project benefits the company in some way, even tangentially. Technology company Google is credited for popularizing the 20% concept. It led to the development of products such as Gmail and AdSense. Though the program's continuity has been questioned Google states it remains an active program. Other major companies that have at one time or another offered some or all of their employees the benefit include the BBC (10%), Apple (a few contiguous weeks yearly), and Atlassian (20%). Some, such as LinkedIn, have trialed more restrictive versions of such initiatives in which employees must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
