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.

Cache human-readable route-values of a Web API or not?
If you're just doing this to avoid Insecure Direct Object Reference (IDOR) problems, then perhaps something like Hashids might be a better choice?
-
Using a Guid as a PK, best practices.
I'm gonna be using this Library https://github.com/ullmark/hashids.net to encode the BIGINT into a string and decode the string back into the BIGINT within my web application.
-
Generating what appears to be a random long from a long, and being able to reliablely convert it back to its orignal value.
If you can use a string, then Markus Ullmark's hashids.net library would be a good place to start.

Does anyone know of a modern, DotNet7/C#10 implementation of this article, which covers tamper-proof hidden fields? They are exceedingly useful for CRUD forms which need to hold - but should never allow modification of - certain values, but I haven’t found an appropriate upgrade path.
You could use this approach along with this package https://github.com/ullmark/hashids.net

Value converter of AutoMapper for hashids
Hashids helps you to convert a number Id to a string, this can make your app a little more secure hiding the actual id or related key of your DB when the data is requested by an API.
-
Is it ok to have sensitive data in cascading values?
Guids are nice, but there’s the option of hashids too. While it’s not advertised as a security mechanism, it does mask the integer and make things harder to guess

UUIDs to Prevent Enumeration Attacks
Another way to solve enumeration attacks is to use a two-way hashing algorithm to convert your auto-incrementing integer IDs to a hash of arbitrary length. This is essentially what YouTube is doing with their video IDs and it's a low-CPU, low-complexity solution that prevents/severely deters enumeration attacks.
Here is one such library for C# https://github.com/ullmark/hashids.net
- how to shorten the two-factor auth key?

The Monad Invasion - Part 2: Monads in Action!
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).

How small is the smallest .NET Hello World binary?
The widely used MediatR library[0] could be used to do that as well, just FYI.

CQRS: How to handle duplicate queries inside a CommandHandler
Hope this GH issue shed some light on why injecting handler inside another handler is not good https://github.com/jbogard/MediatR/issues/400

Easiest way to build the fastest REST API in C# and .NET 7 using CQRS
I gave it a go and I was impressed how easy and fast it was to set it all up. Since I'm not a big fan of REPR pattern almost all my projects are using CQRS pattern with a help of MediatR ](https://github.com/jbogard/MediatR) I immediately started going over something similar that Fast Endpoints offer which is a command bus.

MVVM Question: How do you manage the interaction between Model and ViewModel?
I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.
-
Async Methods after setting a property.
If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.

I don't get why I should use Redux
What people really want is to design the logic of an app independently from the component hierarchy. That means you need to store state somewhere other than the components and you need to dispatch events that are not attached to the component hierarchy. Also, a one way data flow has well known benefits as described by things like CQRS, RabbitMQ, and MediatR.
