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.

Why Rust?
Anyone who's interested in the AccessKit integration can play with my work-in-progress branch: https://github.com/mwcampbell/egui/tree/accesskit
It's currently Windows-only, and I'm working on the big missing feature, which is text editing support.

UIs are not pure functions of the model
> A core premise of Cocoa, and MVC in general, is that UIs are a projection of data into a different form of data, specifically bits on a screen.
This is a tangent, but the implicit assumption that the UI is visual is just begging for a response from an accessibility perspective, so here goes.
Accessibility is very much an afterthought in native GUIs, not only in Cocoa, but also in Windows with the UI Automation API, and AFAIK with other native accessibility APIs as well. With these APIs, the assistive technology (e.g. screen reader) pulls information from the application (usually via the GUI toolkit), through repeated calls to methods defined by the accessibility API. Often the AT has to do several such calls in a row (and those often translate to multiple IPC round trips, making things slow). And the UI might change between such calls; there's no guaranteed way to get a consistent snapshot of the whole thing, as there is with a visual frame. On the application/toolkit side, these methods may return different responses from one call to the next, and the application or toolkit has to fire the right events when things change.
The web improves on this, in that accessibility information is conveyed through HTML tags and attributes. And yes, this is included in the output of a React component's render function. So while in practice, implementing accessibility may still be an afterthought, it's not an architectural afterthought as it is in native platforms.
One of my goals in AccessKit [1] is to work around this shortcoming of native accessibility APIs, particularly for developers of cross-platform non-web GUI toolkits. In AccessKit, the toolkit pushes a full or incremental accessibility tree update to the AccessKit platform adapter, which maintains the full tree in memory and uses that to implement the platform accessibility API. This even works for immediate-mode GUIs, as one can see in my proof-of-concept integration with the Rust egui toolkit [2].

Raygui – A simple and easy-to-use immediate-mode GUI library
I can also report some modest progress on my own work on accessibility of immediate-mode GUIs. I have a branch of the Rust egui library [1] that has basic accessibility on Windows using my AccessKit project [2]. I do have a long way to go to make this fully usable and ready to submit upstream, especially when taking non-Windows platforms into account.

A Practical Approach to Quantum-Resistant JWTs
As the field of quantum computing advances, the need for cryptographic systems that can withstand quantum attacks becomes increasingly critical. The jwt-falcon library addresses this challenge by integrating the Falcon algorithm, a prominent candidate in the NIST Post-Quantum Cryptography competition, into JSON Web Token (JWT). Falcon is designed to offer security against the potential capabilities of future quantum computers. For detailed information on the Falcon algorithm, visit Falcon-sign.info. Under the hood, jwt-falcon utilizes the Falcon-crypto package, a dedicated implementation of the Falcon algorithm for JavaScript environments.

I've been in Algorand for over two years now. Bought many at $2.00 and all the way down. It has been a rough bear market but the fundamentals have only gotten stronger. I'm extremely optimistic about the future. Algorand is still a best in class block chain. Tech will matter eventually.
From the Falcon Keys website:

Microsoft expects to build a quantum supercomputer within 10 years
At the rate quantum computing is developing, the issue of quantum readiness can't be ignored much longer by the cryptosphere. No other blockchain has a team that understands the problem and solution set better than Algorand; they are literally writing the papers that NIST standards are based on . It's going to matter.

Ask HN: Won’t quantum computing destroy most (if not all) crypto?
There are already post-quantum cryptographic algorithms already in existence.
One of the candidates is Falcon [0] proposed by the creators of Algorand.

Quantum Threat to Cryptocurrencies Explained [SERIOUS]
Algorand has actually already been upgraded with FALCON-based keys, which is not surprising given the fact tthat FALCON is actually based on the theoretical framework developed by Algorand's Craig Gentry, Chris Peikert, and Vinod Vaikuntanathan.

Academic cryptographer posted this to r/cc. Isn't aware of Algorand. -> Quantum Threat to Cryptocurrencies Explained [SERIOUS]
Algorand's Craig Gentry, Chris Peikert, and Vinod Vaikuntanathan developed the theoretical framework that Falcon, one of NIST's four approved quantum-hardened encryption algorithms, is based on.
- To endure into the future, Algorand believes that the protocol must be secure against potential post-quantum attacks, while also being able to interoperate and exchange with other blockchain networks. Listen to Algorand head of cryptography Chris Peikert discuss State Proofs and Quantum Security.

Interview about Post-Quantum (Cryptography)
For signing Algorand uses Falcon signatures, which are post quantum and one of NISTs recommendations. There are a few names there that might help. https://falcon-sign.info/
