CardOverflow VS syncthing-android

I tried to build StackOverflow for flashcards (i.e. spaced repetition with collaboration as a first class feature.) After working on it on nights/weekends for ~2 years, I realized my architecture was shit. I started out with Blazor + F# + PostGres, but eventually I realized that syncing offline client DBs to the cloud was a very nontrivial problem. So I moved to event sourcing. Turns out that's not much better - I started to write my own IndexedDB wrapper, then said "you're a moron" and switched to CouchDb/PouchDb/RxDB. I also wanted to support plugins. I thought I figured that out with Blazor, but eventually I realized that more powerful plugins would want to manipulate the DOM directly. Blazor's virtual DOM kills that possibility. So, I'm off the dotnet ecosystem (I can't express how very, very sad I am to leave F#) and onto Typescript + SolidJS. I would've gone ReScript but that's tightly coupled to React which uses the VDom. Perhaps I should be using Svelte - I'm not solid on any of this new architecture yet. So my project has not yet entirely failed... I just realized I spent ~2 years on the wrong architecture.

FWIW I'm building something from the ground up that'll have this sharing/social thang built in. I also (obviously) think that there's a need for collaborative tools for building and sharing cards, along with perhaps ways to publish your progress. For various reasons I'm not building it on Anki though.

I'm building the above thing here: https://github.com/dharmaturtle/cardoverflow

Not only considered - I'm actively using it. You'll find people complaining about IndexedDB's API all over the internet. They're right - it's remarkably terrible. I'm using Dexie.JS as a wrapper over it.

I'm working on an open source edtech website. Prelaunch, but I wouldn't mind talking shop. In the western suburbs.

My dude, speaking as someone who gets really happy when they find a functor in their code, I fully disagree with your last paragraph. You can do FP without knowing anything about the theory. Telling someone that they should read up on a dry, boring academic topic in order to be a better programmer is kinda a nonstarter. When you start throwing around stuff like "You should learn category theory and homotopy theory to really understand FP" only drives people away - it doesn't inspire curiosity (in most people).

I'm working on an edtech thing - think StackOverflow/Wikipedia for flashcards. Basically, there's a way to remember an exponential amount of information - it just isn't popular because the existing software is terrible. Despite the terrible software, it is very popular among med students, since they have to cram so much info into their heads.

> I also hate that the anki shared decks web site does not encourage collaboration...

Dude, I'm building exactly this. I'm not basing it on git for various reasons, but I am using event sourcing, and git is basically event sourcing for code. My system will (eventually) allow pull requests, comments, upvotes/downvotes, and all kinds of community shenanigans on flash cards. It's months away from release... but here's the repo if you wanna have a look: https://github.com/dharmaturtle/cardoverflow

Here's another link that I recently saw about something related which is most likely not interesting for you. Just in case: https://www.reddit.com/r/Anki/comments/nalar8/open_source_web_port_of_anki/ which is about https://github.com/dharmaturtle/CardOverflow

OK, found https://github.com/dharmaturtle/CardOverflow

I've got another one on topic of self-hosted file sharing:

- FileBrowser running in Docker (https://filebrowser.org/features)

- Syncthing running in another container (https://syncthing.net/)

Syncthing keeps the files on your PC, Mac, BSD systems updated, and FileBrowser can point to the share and supply a convenient web UI. It works for me, it's kind of like a local Dropbox-lite.

We use syncthing to share files between our machines. It avoids is having to use dropbox / OneDrive etc. You just choose a folder and it automatically syncs it in the background.

https://syncthing.net/

This very hn entries is bust contradicting your statement.

Also what about syncthing[1] (for recurrent/permanent sync) and croc[2] (for one time copies) ?

I have used both for a number of years already.

[2] https://github.com/schollz/croc

I would use syncthing, which is open source at https://syncthing.net/.

After minimal setup, it just works(tm).

You have a normal directory in your filesystem, that is synced to the other peers (which you set up in the "minimal setup").

I have been using it for years, and it works well. It has no problems crossing os'es (i.e. windows -> linux, linux -> mac)

For windows I usually recommend https://github.com/canton7/SyncTrayzor, but vanilla syncthing works fine too (but don't try to mix them!)

Do consider Syncthing particularly if you are using Android. If using apple iOS you'd need the möbius sync client.

One thing that it beats the cloud / centralized sync on is because the connection is direct between devices when the initial transfer is completed the file is completely there on the other device. With a cloud type of sync you do the transfer twice. I've seen stack up on large media or with the structure of cloud services pricing making it expensive depending on how your workflow is setup with inside and outside parties. For example, Dropbox deduction from all parties' storage limits not just the sharer.

You can also point Syncthing at a local sync of Dropbox or Google drive and then forward the files to other recipients from that for some purposes.

I think sync is a non-feature, as you can just ride on your existing solution.

For example, I use syncthing [1] with Obsidian to sync files off-cloud.

When I was 14 and just getting started, I used Notepad. Upgraded to Wordpad when I realized I loved putting italics in every other sentence, moved to Google Docs at around 25 when I started writing on my phone and wanted to sync with my computer, finally moved to Obsidian a few months ago (with Syncthing for syncing) when I decided I don't want to live in Google's house where they can burn my stuff down whenever they want.
