 Lol, I can make a one-liner:
 
 ```
-alias jekyll_server="lsof -t -i :4000 | xargs kill & bundle exec jekyll serve --drafts --incremental"
+alias jekyll_server="lsof -t -i :4000 | xargs kill && bundle exec jekyll serve --drafts --incremental"
 ```
 
 Well, that was easy.

+# `xargs` for multiple commands
+
+You can use `xargs` in many useful ways.
+
+Install `tldr`, run `tldr xargs`.
+
+Here's how I use it:
+
+```
+git diff <commit> --name-only | xargs atom
+```
+
+Or in aliases:
+```
+alias jekyll_server="lsof -t -i :4000 | xargs kill && bundle exec jekyll serve --drafts --incremental"
+alias run_all_ruby_tests="find ./test -name '*_test.rb' | xargs -n1 ruby"
+```
+
+It grabs the output of the prior commands, and passes it in specific ways to whatever comes after `xargs`, like `kill`, or `ruby`, etc.

+Make sure caveties that you're adding insulation to are deep enough for the insulation. 
+
+If they're not, add narrow strips to get necessary depth (R-20 requires 5.5" of depth, and I live in Colorado, so we're going with R-20)

+# How to Soundproof a Room
+
+I don't know that I'll ever get "soundproofed", but we live in an old house with _horrific_ noise propogation. 
+
+Keep in mind:
+
+- Green glue (1 tube per sheet of drywall)
+- Vynil mass (1/4" on floor, 1/8" on walls)
+- Double sheets of drywall (2 layers 5/8th drywall with green glue between)
+- Air gaps
+- Insulate foam around all outlet/switch boxes
+- avoid air vents if possible

+Remove door casing, all-the way around: [https://youtu.be/xXHeIOEOiAA?t=1122](https://youtu.be/xXHeIOEOiAA?t=1122)
+
+Fill gap between drywall and door frame with expansion foam.
+
+Solid-core door.
+
+Add a door-stop system with a "active sweep" device that seals along floor when door is closed.
+
+
+## Windows
+
+## Walls/Ceilings
+
+Drywall: 2 sheets of 5/8" drywall with glue between, staggered edges
+
+between subfloor and drywall: GreenGlue Sealent
+
+Between Drywall and Drywall: Greenglue soundproofing

+# Parameterize Strings
+
+First, the [String#parameterize](https://www.rubydoc.info/gems/activesupport/5.0.0.1/String:parameterize) method is an ActiveSupport method. It's not available by default to Ruby.
+
+I tried:
+
+```ruby
+require 'active_support'
+```
+
+and `parameterize` was still unavailable. I found [trying to require active_support in gem](https://stackoverflow.com/questions/18732338/trying-to-require-active-support-in-gem), and the [top answer](https://stackoverflow.com/a/18734988/3210178) said:
+
+> You need to `require` the methods you need from `ActiveSupport`; they aren't added by default.
+> 
+> Like Yevgeniy mentions in a comment, the way to do this is `require "active_support/all"` if you need everything - or if you for example want only the Hash extensions use `require 'active_support/core_ext/hash'`
+
+So, cool! I added:
+
+```ruby
+require 'active_support/core_ext/string/inflections'
+```
+
+And it was working!
+
+Next, the _default_ parameterize separator is `-`, but a symbol cannot have dashes, it must be underscored:
+
+```ruby
+:josh_thompson # valid
+:josh-thompson # invalid
+```
+
+If I tried to symbolify the bottom option, I'd get `:"josh-thompson"`, which is bad.
+
+So, want to make strings valid symbols, universally?
+
+```ruby
+"SUPER strange String".downcase.parameterize(separator: '_').to_sym
+=> :super_strange_string
+```
+
+Good to go.
