brew is a bad neighbor

This isn't a guide about locking down homebrew so that it can't touch the rest of your system security-wise.

This guide doesn't fix the inherent security issues of a package management system that will literally yell at you if you try to do something about "huh, maybe it's not great my executables are writeable by my account without requiring authorization first".

But it absolutely is a guide about shoving it into its own little corner so that you can take it or leave it as you see fit, instead of just letting the project do what it likes like completely taking over permissions and ownership of a directory that might be in use by other software on your Mac and stomping all over their contents.

By following this guide you will:

Never have to run sudo to forcefully change permissions of some directory to be owned by your account

Go generics at runtime (part 1 of 2)

From the design document:

Generic functions, rather than generic types, can probably be compiled using an interface-based approach. That will optimize compile time, in that the package is only compiled once, but there will be some run-time cost.

Generic types may most naturally be compiled multiple times for each

Enable Docker Remote API with TLS client verification

Docker's Remote API can be secured via TLS and client certificate verification.
First of all you need a few certificates and keys:

CA certificate
Server certificate
Server key
Client certificate
Client key

Create certificate files
