    Project mention: The Monad Invasion - Part 2: Monads in Action! | dev.to | 2024-02-27

    You probably noticed that .SetName() returns a Either. You may have come across Unit in libraries like MediatR or Language-Ext. It's a simple construct representing a type with only one possible value. We use it as a placeholder for operations that do not return a value but may return another state. In our example, .SetName() is a Command that does not return a value but may fail. Therefore, the monad Either carries two possible states: Right (without value) or Left (with an Error).

  • 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.
