    I don't have personal experience with it, but I've seen NextCloud mentioned a lot. It offers a number of ways to access files (Web browser, smartphone app and desktop client. Since you mentioned Windows File Explorer integration, the desktop client will probably be of interest to you.

    And finally, we arrive at the data. Data versioning has become one of the most discussed topics in the production machine learning community. Unlike code, you can't simply check data into version control easily (although tools like DVC are attempting just that).

  • GitHub repo HackMD

    CodiMD - Realtime collaborative markdown notes on all platforms.

    Project mention: Are there any collaborative note apps like Outline that aren't as complicated to maintain? | | 2021-09-24

    Project mention: My Secure and Private Notetaking Workflow with an Emphasis on Mobile, based on Gitea and Working Copy (alternative to Standard Notes, Joplin) | | 2021-11-19

    Last time I looked into SparkleShare it seemed like it had been abandoned. Looking at the Github it looks like it hasn't seen a release since Nov 2020. That's what turned me off. The Obsidian-git routine works for me now, but maybe I should experiment with it.

  • GitHub repo Activeloop Hub

    Dataset format for AI. Easily build and manage datasets for machine and deep learning. Stream data real-time & version-control it. (by activeloopai)

    Project mention: TileDB VS Activeloop hub - a user suggested alternative | | 2021-10-20
  • GitHub repo FluidFramework

    Library for building distributed, real-time collaborative web applications

    Project mention: Microsoft Launches Google Wave | | 2021-11-02

    (Disclosure: Work at Microsoft, but I work in Azure and some open source stuff, not on or directly with Fluid/Office/etc.)

    That's just a trademark clause for Microsoft logos and brands. The Fluid Framework itself is [MIT licensed]( and doesn't require exposing any of those logos/brands when you use it, so the framework itself is fairly open for usage.

    I think the main thing that would slow down adoption for Fluid is that the only "production" backend is an Azure service, which isn't part of the open source Fluid Framework. [Other open source backends]( aren't recommended for productions. Until there are some open source ones, I'd assume adoption will be limited to folks in the Azure ecosystem.

  • GitHub repo Openfire

    An XMPP server licensed under the Open Source Apache License.

  • GitHub repo mapus

    A map tool with real-time collaboration 🗺️

    Project mention: LeafletJS | | 2021-08-16

    Super handy library. I used it for a real-time collaborative map tool [1], it's especially useful when it comes to customization, plus it has many plugins which add a lot of functionality. Leaflet Geoman [2] for instance is great for creating all sorts of geometries on the map, I've personally used it for my tool so users can designate areas and paths. So good.


  • GitHub repo ONLYOFFICE

    ONLYOFFICE Document Server is an online office suite comprising viewers and editors for texts, spreadsheets and presentations, fully compatible with Office Open XML formats: .docx, .xlsx, .pptx and enabling collaborative editing in real time.

  • GitHub repo terminusdb

    TerminusDB is an open source knowledge graph and document store. Use it to build versioned data products.

    Project mention: Knowledge Graphs | | 2021-10-22

    We have a immutable chain structure in TerminusDB which allows for straightforward uncoordinated multi-read access or multi-version concurrency control. This approach also makes branching simple to implement. Any number of new layers can point to the same former parent layer.
