Community Memory is a pioneering project in the realm of digital community networks. It was initiated by visionaries Lee Felsenstein, Efrem Lipkin, Ken Colstad, Jude Milhon, and Mark Szpakowski. The team worked with unique roles, with Felsenstein focusing on hardware, Lipkin on software, and Szpakowski on the interface do utilizador[1]. The project was deeply influenced by the countercultural ethos of 1960s northern California, and gained presence in Vancouver under the leadership of Andrew Clement in 1974. The initial iteration of Community Memory involved a terminal that utilized a Teletype Model 33 connected to an SDS 940 computador[2]. Later, in the late seventies, the project aimed for a more expansive reach as a global information network. The Community Memory software was based on the ROGIRS system and facilitated user interaction through simple commands like ADD for posting and FIND for searching content. Notably, the platform allowed for anonymity and was not controlled by a central authority.

Definições de termos
1. interface do utilizador. A User Interface, often abbreviated as UI, is a fundamental aspect of any digital product, system, or service. It is the point of interaction between the user and a digital device or product such as a software application or a website. The evolution of UI traces back to the 1940s, progressing from basic interfaces to more sophisticated ones like Graphical and Composite User Interfaces. It's categorized into various types including attentive, batch, command-line, conversational, and object-oriented interfaces, each designed to serve different user needs. UI design revolves around principles and practices that prioritize user ease, efficiency, and enjoyment. This includes elements like layout, color schemes, typography, and interactive components that greatly influence usability, accessibility, and user retention rates. The field of UI design is dynamic, with current trends favoring dark mode interfaces, micro-interactions, 3D elements, and augmented reality. The practice also emphasizes user research, simplicity, intuitive navigation, and iterative improvements.
2. computador. Um computador é um dispositivo sofisticado que manipula dados ou informações de acordo com um conjunto de instruções, conhecidas como programas. Por conceção, os computadores podem executar uma vasta gama de tarefas, desde simples cálculos aritméticos até ao processamento e análise de dados complexos. Os computadores evoluíram ao longo dos anos, desde as primitivas ferramentas de contagem, como o ábaco, até às modernas máquinas digitais. O coração de um computador é a sua unidade central de processamento (CPU), que inclui uma unidade lógica aritmética (ALU) para efetuar operações matemáticas e registos para armazenar dados. Os computadores também têm unidades de memória, como ROM e RAM, para armazenar informação. Outros componentes incluem dispositivos de entrada/saída (E/S) que permitem a interação com a máquina e circuitos integrados que melhoram a funcionalidade do computador. As principais inovações históricas, como a invenção do primeiro computador programável por Charles Babbage e o desenvolvimento do primeiro computador eletrónico digital automático, o Atanasoff-Berry Computer (ABC), contribuíram grandemente para a sua evolução. Atualmente, os computadores alimentam a Internet, ligando milhares de milhões de utilizadores em todo o mundo, e tornaram-se uma ferramenta essencial em quase todas as indústrias.

Memória comunitária (CM) was the first public computerized bulletin board system. Established in 1973 in Berkeley, California, it used an SDS 940 timesharing system in San Francisco connected via a 110 baud link to a teleprinter at a record store in Berkeley to let users enter and retrieve messages. Individuals could place messages in the computer and then look through the memory for a specific notice.

While initially conceived as an information and resource sharing network linking a variety of counter-cultural economic, educational, and social organizations with each other and the public, Community Memory was soon generalized to be an information flea market, by providing unmediated, two-way access to message databases through public computer terminals. Once the system became available, the users demonstrated that it was a general communications medium that could be used for art, literature, journalism, commerce, and social chatter.
