Anki – Powerful, intelligent flash cards
> I wonder what the ecosystem would look like if things were otherwise.
Shameless plug - I'm building https://github.com/AlexErrant/Pentive which is basically GitHub/Reddit for flashcards. Very much pre-product and a WIP, though the offline client proof of concept is done.

Lessons from building GitHub code search [video]
I also enjoyed the Treesitter talk from 5 years ago by Max Brunsfeld https://www.youtube.com/watch?v=Jes3bD6P0To
I'm currently building a query language whose grammar is very much inspired by Github's search syntax. I'm using Lezer, which is a GLR like Treesitter, so this talk learned me some parser generators (I've no formal CS education). Here's my grammar, a playground, and an example search query if anyone wants to play with it

Using spaced repetition systems to see through a piece of mathematics
Not really. There are options for sharing cards on Anki https://www.reddit.com/r/Anki/comments/14j2jfy/deck_sharing_... but their collaboration features are limited.
I myself am building an Anki clone https://github.com/AlexErrant/Pentive with collaboration built in as a first class citizen, though its far from primetime. Currently stewing on how to get the SR algorithm, FSRS, to compile to wasm.

Ask HN: Show me your half baked project
https://github.com/AlexErrant/Pentive
A free, open source, local-first, spaced repetition system that works offline, has p2p syncing, plugins, and first class support for collaboration. It's GitHub/Reddit for flashcards.
I basically took Anki and turned it into a webapp >_>

Things you forgot because of React
I find Solid's model pretty damn close to "compiling down to nothing". I chose Solid for my project because I wanted to support plugins that used other UI frameworks. I recently got a Svelte plugin working with the SolidJS router. I could probably make it prettier... but it's literally a call to Solid's `createComponent` with the Router and an anchoring div to which the Svelte component is mounted. Ezpz.

An open source web-based flashcard studying system
I'm also building an Anki clone (sigh) that I'm calling "Github for flashcards".
>A free, open source, local-first, spaced repetition system that works offline, has p2p syncing, plugins, and first class support for collaboration.
https://github.com/AlexErrant/Pentive
Very much a WIP, completely unusable, but I recently made a video demoing the technical proof of concept.

Anki-Fy Your Life
Anki, imo, already has an open algorithm (that the user can change via plugins), universal interfaces, and is "self-hosted". My eyes perked up at REST api, but it doesn't look like there's a centralized server that hosts shared cards, which is where my mind went.
I'm building https://github.com/AlexErrant/Pentive/ which is basically Anki + Reddit - people can optionally upload their cards for others to download, and the most popular cards rise to the top. It's FLOSS, offline-first, supports plugins and p2p syncing, and is very much a WIP. My proof of concept is almost done though, which demos the critical technologies in a secure way.

A Gentle Introduction to CRDTs
I'm using cr-sqlite right now in my Anki clone: https://github.com/AlexErrant/Pentive
It's basically an offline-first flashcard webapp. CR-Sqlite allows for incremental syncing.
With Anki (the app from which I'm taking my inspiration), syncing is _not_ incremental - basically it just copies SQLite files around. So for example, the app could be on an iPhone with cards a card `A` reviewed, but the app on an iPad could make changes to the template on which card `A` is based, and that's enough to cause a conflict - you must take changes from only the iPad or only the iPhone. (To be clear - Anki does have some incremental syncing capabilities - I'm picking an intentionally pathological example.) CR-SQLite will mean that everything is incremental, however.
Basically makes 3 way merges a breeze (or n-way merges, really).

Ask HN: What Are You Working on This Year?
A FLOSS, offline-first, spaced repetition system that has first class support for collaboration, curation, and plugins. It's Reddit for flashcards.
https://github.com/AlexErrant/Pentive
I've been thinking about this for a stupid amount of time... thinking that someday someone's going to improve on Anki. Finally got tired of it and said that person's me.
