Pangea Jurisdiction and Pangea Arbitration Token (PAT)
Pangea Jurisdiction and Pangea Arbitration Token (PAT) The Internet of Sovereignty Susanne Tarkowski Tempelhof, Eliott Teissonniere James Fennell Tempelhof and Dana Edwards Bitnation, Planet Earth, April 2017 Pangea Jurisdiction and Pangea Arbitration Token (PAT) The Internet of Sovereignty Susanne Tarkowski Tempelhof, Eliott Teissonniere, James Fennell Tempelhof and Dana Edwards Bitnation, Planet Earth, April 2017 <abstract_ The Pangea software is a Decentralized Opt-In Jurisdiction where Citizens can conduct peer- to-peer arbitration and create Nations. Pangea uses the Panthalassa mesh, which is built using Secure Scuttlebutt (SSB) and Interplanetary File System (IPFS) protocols. This enables Pangea to be highly resilient and secure, conferring resistance to emergent threats such as high- performance quantum cryptography. Pangea is blockchain agnostic but uses the Ethereum blockchain for the time being. In the future, other chains such as Bitcoin, EOS and Tezos can be integrated with Pangea. The Pangea Arbitration Token (PAT) is an ERC20 compatible in-app token for the Pangea Jurisdiction. The PAT token rewards good reputation and is issued on Pangea when Citizens accumulate non-tradable reputation tokens through creating a contract, successfully completing a contract or resolving a dispute attached to a contract. PAT is an algorithmic reputation token, an arbitration currency based on performance rather than purchasing power, popularity or attention. The distribution mechanism for PAT tokens on Pangea is an autonomous agent, Lucy, which will initially launch on Ethereum as a smart contract. This mechanism is blockchain agnostic and can be ported to any viable smart contract platform. An oracle created by Bitnation will help to facilitate this (semi-) autonomous distribution mechanism in a decentralized and secure fashion. -

Nextcloud Desktop Client for Linux
EOAS Help Desk Portal > Knowledgebase > Linux > NextCloud desktop client for Linux NextCloud desktop client for Linux Tom Yerex - 2020-02-19 - 0 Comments - in Linux Access to the EOAS NextCloud server can occur over several different protocols including WebDAV and over the web using a browser. The NextCloud desktop client synchronizes files and folders from your Linux workstation to the NextCloud server. Once the Linux desktop client is installed and you have it configured, the client will periodically check the server for updated files, as well as copy updated files from your workstation to the server. To begin to use the NextCloud Linux desktop client, visit the NextCloud web site at https://nextcloud.com/install/#install-clients, select Linux , on the same page below read the paragraph about Nextcloud Desktop client packages for your Linux distribution. Once you have downloaded the client specific to your operating system, you must follow the distribution-specific steps for installing the client. The desktop agent will prompt at launch for the server address, user name, password, and finally the files/folders that you wish to synchronize. Server: owncloud.eoas.ubc.ca User name: <your EOAS account> Password: <your EOAS password> Once the initial configuration is complete, the NextCloud desktop client will begin to synchronize files/folders with the server, pulling down any files that you may have on the server as well as uploading any new files you have on your local desktop. If you have any questions or concerns, please contact the EOAS IT Help Desk, by email at [email protected], or by using our contact form.. -

Weiterführende Links Die Informationen zu den verschiedenen Anwendungen wurde zusammengestellt von der AKS Gemeinwohl. Für die Inhalte externer Links wird keine Haftung übernommen. Stand: 31.03.2020. 1. Projektmanagement-Tools zur Organisation und Koordination factro 1. Funktion: Factro ist ein Projektmanagement-Tool, das als Alternative zu Asana präsentiert wird. Man kann Aufgaben mit entsprechenden Deadlines einzelnen Teammitgliedern zuordnen sowie über eine Kommentarfunktion bestimmte Punkte erläutern, Fragen stellen etc. Die Grundstruktur basiert, ebenso wie bei Trello und Asana, auf dem Kanban Prinzip. 2. Datenschutz und Server: Der große Vorteil von Factro ist, dass dessen Server in Deutschland (Frank- furt/Main) stehen. Die Software wurde von dem Bochumer Unternehmen Schuchert Management- beratung entwickelt, das vor allem mittelständische Unternehmen berät. Zudem arbeitet factro nur mit Anbietern aus Deutschland und der EU zusammen. Es wird großen Wert auf Datenschutz gelegt. Es werden zwar Cookies von Google Analystics verwendet, wobei die damit erhobenen Daten wieder auf US-Servern gespeichert werden, allerdings kann man diese Cookies ausschalten. Factro gibt einem insgesamt ausführliche Möglichkeiten, über die Nutzung seiner Daten selbst zu entscheiden. 3. Zugänglichkeit: Die Basic-Version ist kostenfrei und kann von bis zu zehn Mitgliedern benutzt werden. Für kleine Teams mit einigermaßen übersichtlichen Arbeitsabläufen ist dies völlig ausreichend. Die erste Bezahlstufe liegt bei 7,99€ pro Monat. Das Interface ist sehr zugänglich, einfache Funktionen sind schnell anwendbar. 4. Fazit: Factro ist eine gute, wenn auch kommerzielle Alternative zu Asana oder Trello. -

New technologies should fit in the existing architecture rather than putting further demands on the IT department while protecting confidential information and preventing it from ending up in consumer grade applications. You need a solution which lets you leverage existing infrastructure without duplicating or moving data. A solution which puts you in control while bringing a modern, on-the-go and easy to use experience to your users. Nextcloud provides a common file access layer through its Universal File Access, keeping data where it is and retaining the management and control mechanisms IT currently has in place to manage risk. By leveraging existing management, security and governance tools and processes, deployment is made easier and faster. Nextcloud brings data from cloud storage, Windows network drive and legacy data storage to users in a single, easy interface empowering them to access, sync and share files on any device, WebDAV Clients Browser wherever they are, managed, secured and controlled by IT, see Figure 1. It complements this functionality with optional integrated communication and collaboration tools like online document editing, audio/video chat and more.

Enterprise File Synchronization and Sharing Services for Educational Environments in Case of Disaster
Ana Isabel Delgado-Domínguez - Walter Marcelo Fuertes-Díaz - Sandra Patricia Sánchez-Gor- don Enterprise file synchronization and sharing services for educational environments in case of disaster Servicios de sincronización y almacenamiento de archivos para entornos educativos en caso de desastre Serviços de sincronização e armazenamento de arquivos para ambientes educativos em caso de desastre Ana Isabel Delgado-Domínguez* Fecha de recepción: 1 de septiembre de 2017 Walter Marcelo Fuertes-Díaz** Fecha de aprobación: 2 de diciembre de 2017 Sandra Patricia Sánchez-Gordon*** Abstract Cloud computing is an emerging solution that responds to the concept of Smart University; it aims at offering an intelligent environment of business continuity for the actors of an educational center. This research offers a recovery plan of educational services in case of disaster, through an action research, which analyzed free software for cloud computing, focusing on Enterprise File Synchronization and Sharing (EFSS). To achieve this, the implementation was placed in a local scenario (Linux Apache, MySQL, PHP, LAMP), and stress tests were performed on three applications: Nextcloud, Seafile and Pydio. Nextcloud had more consistent and better results than the other two applications; however, it lacks a system that allows synchronizing two Nextcloud instances. To solve this, we developed a routine aimed at providing an environment that monitors the hot site where the application is hosted and, from time to time, synchronize the instance to avoid data loss during disaster events. Afterwards, we configured a second application on a cold site that is alert to a possible service breakdown, so it can respond and sent immediate alerts.
