    ownCloud

    ownCloud

    ownCloud web server core (Files, DAV, etc.)

    ownCloud Core is the foundational server component of the ownCloud ecosystem, providing a self-hosted platform for secure file storage, synchronization, and sharing across devices and teams. It enables organizations and individuals to maintain full control over their data by running a personal cloud on their own infrastructure rather than relying on third-party providers. The software supports collaborative workflows by allowing users to upload, organize, and share files through a web interface, desktop sync clients, and mobile integrations. Designed with extensibility in mind, the core platform can be enhanced through apps and plugins that add capabilities such as document editing, authentication methods, and workflow automation. It is widely used in enterprise and privacy-focused environments because it combines open-source transparency with enterprise-grade controls and permissions.

    Connected React Router

    Connected React Router

    A Redux binding for React Router v4

    Synchronize router state with redux store through uni-directional flow (i.e. history -> store -> router -> components). Supports React Router v4 and v5. Supports functional component hot reloading while preserving state (with react-hot-reload). Dispatching of history methods (push, replace, go, goBack, goForward) works for both redux-thunk and redux-saga. Nested children can access routing state such as the current location directly with react-redux's connect. Supports time traveling in Redux DevTools. Wrap your react-router v4/v5 routing with ConnectedRouter and pass the history object as a prop. Remember to delete any usage of BrowserRouter or NativeRouter as leaving this in will cause problems synchronizing the state. Place ConnectedRouter as a child of react-redux's Provider. If doing server-side rendering, you should still use the StaticRouter from react-router on the server.

    render-async

    render-async

    render_async lets you include pages asynchronously with AJAX

    render_async is here to make your pages show faster to users. Pages become faster seamlessly by rendering partials to your views. Partials render asynchronously and let users see your page faster than using regular rendering. It works with Rails and its tools out of the box. A quick overview of how render_async does its magic. User visits a page, render_async makes an AJAX request on the controller action, controller renders a partial, partial renders in the place where you put render_async view helper. JavaScript is injected straight into <%= content_for :render_async %> so you choose where to put it. Advanced usage includes information on different options. render_async renders an element that gets replaced with the content of your request response. In order to have more control over the element that renders first (before the request), you can set the ID of that element.

    Lotus Notes to Google Calendar tool

    Lotus Notes to Google Calendar tool

    One-way synchronization from Lotus Notes Calendar to Google Calendar

    This is a one-way sync program that will sync your Lotus Notes Calendar to your Google Calendar. No installation is required. Includes many options such as automatic syncing at specified intervals. *Important Privacy Information: https://sourceforge.net/p/lntogoogle/wiki/PrivacyPolicy/ *** Information Update, September 2020: *** Recent issues with Google Synchronization should be fixed with version 1.9.2 which is available for download, now. For typical installation pitfalls, see: https://sourceforge.net/p/lntogoogle/wiki/InstallationPitfalls/ The project was not maintained since its last update in February 2015. However, since I've tracked more than 15.000 Downloads over the last 5 years and still more than 1 million Calendar API-Calls per day, I assume that the tool is still very much in use. So I decided to go back to work. More info: https://sourceforge.net/p/lntogoogle/wiki/Home/ Donations appreciated

    Syncplay

    Syncplay

    Synchronize your playback over the Internet

    Syncplay synchronises the position and play state of multiple media players so that the viewers can watch the same thing at the same time. This means that when one person pauses/unpauses playback or seeks (jumps position) within their media player then this will be replicated across all media players connected to the same server and in the same 'room' (viewing session). When a new person joins they will also be synchronised.

    SyncManager

    SyncManager

    Sync manager that helps you sync your files across different locations

    SyncManager is a custom-made lightweight synchronization manager that helps you synchronize files and folders across different locations. SyncManager lets you synchronize your data in two ways: manually or automatically. Manual syncing mode lets you decide what and when to synchronize data, while automatic syncing mode synchronizes data based on its average synchronization time. It also offers three distinct synchronization types: two-way, one-way, and one-way update, allowing you to synchronize data between folders in different ways. Plus, it has filtering and customizable versioning settings that help you to set synchronization more precisely. You can also decide how to handle old versions of files and folders: move them to the trash, delete them permanently, or version them in a special folder. The utility is operating as a fully automated solution that seamlessly launches at system startup.

    Load AD Contacts

    Program to synchronize AD user objects of different AD forests

    Synchronize address data (e.g. Outlook Global Address List (GAL)) between different Active Directory (AD) forests. The process is as follows: 1) Export user objects of source forest using LDIFDE (a tool provided by Microsoft) 2) Use the program LoadADContacts2 to determine differences between this export and the specified OU of the target AD forest. 3) Update the OU of the target AD forest using LDIFDE using the output of LoadADContacts2 Now users in the target forest can see the users of the source forest in their Global Address List. Notes: - User objects of the source AD forest are imported as contact objects into a selected OU of the target AD forest. - LoadADContacts2 does not update the AD, LDIFDE is used for updates. Therefore tracking of updates is easy. - Only changes are loaded to the target OU. - Various options can be selected: See usage when starting LoadADContacts2 without arguments. - Sample .bat files are provided.
