Unity physics reminder: Since 2015 moving static colliders does NOT cause performance penalties. No need to add a rigidbody. However, collisions and friction involving these colliders won't be simulated correctly.

Unity code optimizations

Comparison of some Unity functions. Interesting video, but all benches are done in the editor, and he mentions LINQ tests in WebGL yielding completely different results, so probably other tests might be not so correct for your platform too. Remember to always profile your code on the target platform for performance critical sections.
And regarding heavy Unity functions: for 99.9% of games performance-wise it is enough to just not use them in Update(). The amount of iterations he uses for benches clearly shows that even heavy functions being called only on init are not going to be a big problem in most cases. But as usual, don't believe me or him, profile yourself.

Sins Of Code Readability

Sin 1 Favoring Cleverness over Clarity.
Sin 1a: Brevity is not clever-ity.
Sin 2: Overly Generic Function Signatures.
Sin 3: Comments Inside Functions.
Sin 3a: Soft Code is a Soft Sin.
Sin 4: Comments Instead of Self-Documentation.
Sin 5: Failing The Squint Test.

YouTube Triggering Ragdoll Physics (Unity Tutorial) In this video we're going to look at how we can implement Ragdoll physics in Unity. First of all, we’ll look at how to configure a ragdoll for a character and then we’ll look at how to activate the ragdoll when the character's killed. We’ll also look at…

Ruben Gonzalez | Dependency Injection on Unity

Make sure to read the second part. Far from ideal DI implementation, but worth to read if you'd like to understand how DI containers might work under the hood.

Modern C# in Unity3D Dependency Injection on Unity Many has been written about dependency injection, even Unity folks wrote about it long time ago, and there are some good frameworks like Zenject, so what is so cool about dependency injection?

Immediate Window – Interact with your Code while Debugging in Rider

In case you missed this feature like I did: the Immediate Window in Rider debugger. A valuable part of the debugging experience is experimentation, modifying variables and determining whether the outcomes were what we expected. The post has a simple example, would be glad to hear your ideas how it could be helpful in the comments.

Improve C# code performance with Span<T>

Obviously fast Span<T> is not available in Unity yet, but the post has an interesting point about how applying domain knowledge could result in better performance than just using new fancy stuff
