  • Project mention: Show HN: QuIDE 2 – cross plattform quantum-circuit designer | news.ycombinator.com | 2024-05-31

    At our research chair (https://mnm-team.org) we used QuIDE (https://quide.eu) quite a lot to try out quantum circuits and teach quantum computing to our students. As many of us were not using Windows that was kind of annoying, because it was only running on Windows.

    So one of our students refactored QuIDE for Windows (https://quide.eu) together with us with Avalonia UI (https://avaloniaui.net/) for cross platform use on Linux, macOS and Windows.

    I think it's now in a state to be used as replacement for the old version. We're happy about new users and contributors.

  • Project mention: Runtime code generation and execution in Go | news.ycombinator.com | 2024-05-29

    This looks like a fun project but for serious work, if you need runtime codegen, you should use .NET which has been successfully using reflection and IL emit for more than a decade:

    - Regex https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...

    - Json https://github.com/neuecc/Utf8Json/tree/master?tab=readme-ov... (this project is archived but nonetheless impressive and continues to show good numbers despite obsoletion)

    - LINQ to DB query compilation https://github.com/dotnet/efcore/blob/main/src/EFCore/Query/...

  • ArchiSteamFarm

    C# application with primary purpose of farming Steam cards from multiple accounts simultaneously.

  • Project mention: Is still safe to use steam idle? | /r/Steam | 2023-12-07

    Why should they? But be sure to use Open Source Projects like https://github.com/JustArchiNET/ArchiSteamFarm or https://github.com/JonasNilson/idle_master_extended so that no funny business happens due to your account due to shady idler programs. Idler programs simply mimic what you're doing and Steam doesn't care about you actually played the game or idled the time since Playtime is IR-reversible and the more you idle, the more you can't refund the game which suits them well.

  • Json.NET

    Json.NET is a popular high-performance JSON framework for .NET

  • Project mention: Why, after 6 years, I'm over GraphQL | news.ycombinator.com | 2024-05-30

    In my opinion, the single biggest issue with Newtonsoft.Json is https://github.com/JamesNK/Newtonsoft.Json/issues/862.

    Sure, you can disable it, but the fact that it is opt-out to begin with - i.e. that by default the parser will try to creatively interpret any string it sees in JSON input and convert in a locale-specific manner that also quietly loses data - is, frankly, insane through and through. I've personally run into this issue many times in existing code - it usually happens when people first start using the library and just never run into any inputs that would trigger this behavior while testing. Then once that code is shipped, someone somewhere just happens to have the data that triggers it.

    And if you look at the comments to that issue, there are numerous mentions from other GitHub repos due to bugs it caused for them, including some Microsoft projects.

    The cherry on that cake was author's response indicating that he doesn't even understand why this design is problematic in the first place: "I like what it does, I have no plans to change it, and I would do it again if given the chance." I wouldn't trust any parser written with this kind of attitude.

If a database is not used and Bogus populates list of data each time an application runs, the data is random, never the same. Also, the random data generated by Bogus may not meet a developer’s requirements.
