The Cost Of async/await On The Build Size

Knowing how async/await works under the hood, I was interested in understanding the impact on the build size, as the compiler does its magic and for each async method generates the state machine consisting of hundreds of lines of code. During IL2CPP phase this amount grows even further, so code growth definitely should cause build size to increase, let's find out the actual impact in this analysis.

PackageEditor: A tool for Unity to edit a git package within the package manager

The package editor is a tool that allows you to edit a package that is installed using a git URL via the Unity Package Manager by creating a local copy of the package.
This allows you to edit the package in the project, and then push the changes to the source repository. Then once you are done, you can revert to the original "production" package using this tool.

unity-toolbar-extender: Extend the Unity Toolbar with your own Editor UI code.

Can come quite in handy, for instance when you have to frequently switch between multiple scenes. However I prefer to create shortcuts for frequent repetitive actions.

Hot reload: a tool which lets you skip all compile times in Unity

It uses a custom C# compiler integration, and only compiles the code that was changed. That output is used to patch up the existing C# code while it's running. It works both inside and outside of playmode.
There shouldn't be any serious risk as you can always just recompile the code normally to reset any bad changes which may have failed to apply (i.e. when using some unsupported features).
It doesn't currently support changes that would require vtable modifications like having a type implement another interface or adding an override to an existing virtual method. There are some other unsupported features that can be checked in the docs, but generally it covers a lot of use cases and can be really useful.

Demystifying Floating Point Precision

Floating point numbers have limited precision. You have likely encountered bugs where things start breaking after too much time has elapsed, or after something has moved too far from the origin.
This post aims to show you how to answer the questions:
What precision do I have at a number?
When will I hit precision issues?

How to build Hot Reload For Unity

2 hot reload tools have been released recently (shared the previous one here before).
The author of this one also provided a tutorial with basics of the hot reload implementation.
