hascard VS CardOverflow

hascard: nice commandline and markdown, but doesn't do spaced repetition. https://github.com/Yvee1/hascard

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
