Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.

Neat Parallel Output in Python
There is an open issue [1] on GitHub to make it more modular and get rid of markdown and syntax highlighting but I have no hope for rich to get more minimal.

Python 3.12
They keep getting improved error messaging and this is one of my favorite features. But I'd love if we could get some real rich text. Idk if anyone else uses rich, but it has infected all my programs now. Not just to print with colors, but because it makes debugging so much easier. Not just print(f"{var=}") but the handler[0,1]. Color is so important to these types of things and so is formatting. Plus, the progress bars are nice and have almost completely replaced tqdm for me[2]. They're just easier and prettier.

[1] Try this example: https://github.com/Textualize/rich/blob/master/examples/exce...
[2] Side note: does anyone know how to get these properly working when using DDP with pytorch? I get flickering when using this and I think it is actually down to a pytorch issue and how they're handling their loggers and flushing the screen. I know pytorch doesn't want to depend on rich, but hey, pip uses rich so why shouldn't everyone?

colors.crumb - first Crumb usable. Extending Crumb with basic terminal styling and RGB, HEX, ANSI conversion functions.
colors.crumb extends Crumb with basic terminal styling functions and RGB, HEX, ANSI conversion functions. It is in the realm of JavaScript's chalk and Python's rich but slightly more functional 😉.

Textual: Rapid Application Development Framework for Python
I am working on a new python project and one of the first things I added was https://github.com/Textualize/rich because of how easy it is to make things look good in the terminal.

I made a library for making user terminal input really really pretty!
You might consider taking inspiration from the rich module. In particular, I like how rich supports inline color theming which seems much more cumbersome in your framework, requiring the use of context managers as well as familiarity with how your framework structures color objects. Other than that though, I'm impressed!
