  • QR-Code-generator

    High-quality QR Code generator library in Java, TypeScript/JavaScript, Python, Rust, C++, C.

  • Project mention: How to make a QR code with Stable Diffusion | news.ycombinator.com | 2023-06-11

    The funny thing is that no-one AFAICT has realized that the same content can be encoded in different-looking QR codes. Beside the obvious (different error-correction levels), the content itself can be changed while maintaining its semantic meaning (e.g. "https://example.com/foo", "HTTPS://EXAMPLE.COM/foo", or "HtTpS://eXaMpLe.CoM/foo" are all semantically identical) and even the QR encoding itself can be tweaked (e.g. by changing the version and mask, see the demo on https://www.nayuki.io/page/qr-code-generator-library). Each combination would yield a different-looking QR code that would encode the same meaning, and it could therefore allow the diffusion models even greater freedom.

    I'm sure somebody will get to this soon.

  • Apache Shiro

    Apache Shiro

  • Project mention: Serverless Apache Zeppelin on AWS | dev.to | 2024-02-04

    The only missing feature in this architecture is the login and logout capability. In this case, Apache Zeppelin provides Shiro for notebook authentication. Apache Shiro is a powerful and easy-to-use Java security framework that performs authentication, authorization, cryptography, and session management. Here, you can find a step-by-step guide about how Shiro works. This example uses the default configuration.

  • Apache Log4j 2

    Apache Log4j 2 is a versatile, feature-rich, efficient logging API and backend for Java.

  • Project mention: Hackers exploited Windows 0-day for 6 months after Microsoft knew of it | news.ycombinator.com | 2024-03-05

    I don't think that's a good example. While Apache devs are volunteers and Microsoft devs are employees, they were criticized for their slow response time and seeming lack of urgency until it was far too late.

  • MaterialFX

  • Project mention: RecyclerView + Glide alternatives? | /r/JavaFX | 2023-07-10

    You can have a look at the VirtualizedFX which is a virtual flow that is written from scratch and inspired by Flowless. The author Palexdev (I think the person is on reddit), took inspiration from Flowless, and has documented the code quite well. You can have a look and also implement a virtual grid with it such as a GridView. Honestly, I tried making my virtual flow, that is simple with a few classes as possible (with adequate success), and the inspiration came from it. The VirtualizedFX has now been incorporated in MaterialFX which is another main project by the same author.
