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

Development environment with Nix Flakes and Direnv

This document is targeted at those who seek to build reproducible dev environment across machines, OS, and time.

It maybe easier for remote teams to work together and not spending hours each person setting up asdf/pyenv/rbenv, LSP servers, linters, runtime/libs. Nix is probably the closest thing to Docker in terms of development environment.

Flake is used here because it provides hermetic build, with absolutely no reliance on system environment (be it Arch/Catalina/Mojave). Also it freezes dependencies in flake.lock so builds are reproducible.

This gist provides the setup to develop Java/Clojure/Python applications on Nix. But it can be easily adapted to ruby, nodejs, haskell.

Nerd Fonts for your IDE

https://www.nerdfonts.com/font-downloads

The following solution thanks to @hackerzgz & @snacky101 will install all nerd fonts;

brew tap homebrew/cask-fonts
brew search '/font-.*-nerd-font/' | awk '{ print $1 }' | xargs -I{} brew install --cask {} || true

Super fast, keyboard-optimized, client side Hugo search

This is a fork of and builds upon the work of Eddie Webb's search and Matthew Daly's search explorations.

It's built for the Hugo static site generator, but could be adopted to function with any json index compatible with Fuse fuzzy search library.

To see it in action, go to craigmod.com and press CMD-/ and start typing.

Building Static Sites with Middleman on S3

In 2015, I converted haughtcodeworks.com to a static site built with Middleman and hosted on S3 and CloudFront. I was asked how I went about that so this gist documents what I did, as best as I can recall. It's been nearly two years since then so some of the gems and tools may have changed for the better.

You may wonder why I shifted to a static site given how dynamic web content is these days. I've known for years that static sites are ideal for certain kinds of content and after hearing about Middleman for the upteenth time, I decided that when it was time to refresh our website, I'd take a look.

As a Ruby programmer, I found that Middleman allowed me to work in the same fashion as I did in Rails yet generate static content. I could still use data or Ruby code to customize how I generated the site.

Cost was another benefit. My monthly hosting bill is $0.13, which includes CDN features via CloudFront. How can you argue with that price? There were a

I upgraded to El Capitan, with Homebrew & Ruby, and this is how I did it flawlessly.

... and Xcode and Java, etc.

Prepare

If you don't already have homebrew installed, do that first, so you don't have to deal with SIP issues. Install all Software Updates available in the Apple Menu, up to and including El Capitan.

Hardware

Jekyll NavBar

In building a site powered by Jekyll and hosted by GitHub, I wanted the ability to highlight the current page's tab in the bar. I also wanted the bar to support second-level items (i.e. a dropdown), which proved somewhat tricky. This is the solution I arrived at after a few hours of fiddling around.

Construction

The contents of the navigation bar are contained in a data file located at _data/navigation.yml. This makes it accessible via the site-wide Liquid element {{ site.data.navigation}}. You can see the file for the formatting I used.

	# can cause a warning when submitting to the App Store. Secondly, to ensure that the build number
	# is incremented appropriately when git has changes.
