Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

List All System Images Available for Download: sdkmanager --list | grep system-images
Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

It's hard to quarrel with that ancient justification of the free press: "America's right to know." It seems almost cruel to ask, ingeniously, "America's right to know what, please? Science? Mathematics? Economics? Foreign languages?"

None of those things, of course. In fact, one might well suppose that the popular feeling is that Americans are a lot better off without any of that tripe.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way throughout political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

Politicians have routinely striven to speak the language of Shakespeare and Milton as ungrammaticaly as possible in order to avoid offending their audiences by appearing to have gone to school. Thus, Adlai Stevenson, who incautiously allowed intelligence and learning and wit to peep out of his speeches, found the American people

	# This is useful mostly for plug-in developer that would like keep developing without turning SIP off.

	# Update 2022-03-10: Based on Fabian's feedback, add capability to inject DYLD for sanitizers.
	#
	# Please note:
	# - Modern Logic (on M1s) uses `AUHostingService` which resides within the system thus not patchable and REQUIRES to turn-off SIP.
	# - Some hosts uses separate plug-in scanning or sandboxing.
	# if that's the case, it's required to patch those (if needed) and attach debugger to them instead.
