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

Let's Destroy C

I have a pet project I work on, every now and then. CNoEvil.

The concept is simple enough.

What if, for a moment, we forgot all the rules we know. That we ignore every good idea, and accept all the terrible ones. That nothing is off limits. Can we turn C into a new language? Can we do what Lisp and Forth let the over-eager programmer do, but in C?

In case there's already a DHCP config for netplan for the private IP address:

File: /etc/netplan/50-cloud-init.yaml

start by adding a new extension target to your iOS app of type “content blocker”
launch the app using the main target’s scheme + a call to SFContentBlockerManager.reloadContentBlockerWithIdentifier() with the extension’s id in application:didFinishLaunchingWithOptions: to auto-reload the blocker in development mode
if you don’t call reloadContentBlockerWithIdentifier() then you need to switch the blocker off and on again in the Safari settings (stop the app in Xcode if the switch is not moving)
use inspector from desktop Safari to inspect the Safari in the simulator in order to find specific things to block
things like periods in the url-filter regexp need to be escaped with double backslashes, e.g. facebook\\.net
if you use if-domain, it needs to be an array, even for one element
domain foo.com might not match www.foo.com even though I think it’s supposed to (UPDATE: They've changed it in one of

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

Example: https://gist.github.com/atenni/5604522/raw/
Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]
