+# Find System-wide Config File For User
+
+The `jj` CLI can be configured in a couple different places. When I recently
+ran a `jj config` command, I was curious where specifically it was getting set.
+Those changes didn't appear in the repo's config (`./.jj/repo/config.toml`).
+That makes sense since it would only apply to that repo. So, where is the
+system-wide config file?
+
+The following commond shows where on your machine it is located.
+
+```bash
+$ jj config path --user
+/Users/jbranchaud/Library/Application Support/jj/config.toml
+```
+
+Now, the next time I set a config like this:
+
+```bash
+$ jj config set --user ui.paginate never
+```
+
+or want to check what other config options are set to, I can visit that path
+and take a look.

+# Write System Clipboard To A File
+
+MacOS has two CLI utilities `pbcopy` and `pbpaste` which, respectively, copy
+_to_ and paste _from_ the system clipboard via the CLI.
+
+Let's say I've just copied a large block of text from somewhere onto my system
+clipboard. I now want to paste that into a new file. Instead of creating a new
+file, opening it up in my preferred editor, pasting all that text, and saving
+the file, I can run one small command from the CLI.
+
+```bash
+$ pbpaste > data.txt
+```
+
+This redirects the contents of `pbpaste` (which is the system clipboard) into
+the file `data.txt`. If that file doesn't already exist, then it will be
+created before the data is written to it.
+
+See `man pbpaste` for more details.

+# Organize Pages In Route Groups
+
+With the Next.js App Router we can organize pages without affecting the URL
+path structure by nesting those directories and pages within a _Route Group_. A
+Route Group is directory where the name is surrounded by parentheses, e.g.
+`/(symbols)`.
+
+For instance, in my [Ruby Operator
+Lookup](https://www.visualmode.dev/ruby-operators) project, I have the
+following structure:
+
+```bash
+$ exa --true src/app/ruby-operators
+
+src/app/ruby-operators
+├── (symbols)
+│  ├── ampersand
+│  │  └── page.mdx
+│  ├── arbitrary-keyword-arguments
+│  │  └── page.mdx
+│  ├── asterisk
+│  │  └── page.mdx
+│  ├── at-symbol
+│  │  └── page.mdx
+│  ├── backtick
+│  │  └── page.mdx
+│  ├── ...
+│  └── underscore
+│     └── page.mdx
+├── client-layout.tsx
+├── layout.tsx
+├── page.tsx
+└── wrapper.ts
+```
+
+I'm able to organize all the different symbols and operators under a separate
+directory `/(symbol)/`. That makes development easier. However, the end result
+routing still has each symbol located directly under `/ruby-operators/`, e.g.
+`/ruby-operators/ampersand`.

+# Block Syntaxes Have Different Precedence
+
+There are two syntaxes for defining a block in Ruby. The semantically shorthand
+syntax uses the curly braces (`{}`). The semantically multi-line syntax uses
+`do` and `end`. For nearly all intents and purposes they are interchangable.
+
+It is, however, worth noting that the `do`/`end` version has a lower precedence
+than the already low precedence of `{}`. That said, you have to write some
+weird code for this to become an issue.
+
+Let's say we have two methods, `method_one` and `method_two`. They are both
+called on the same line like below and then followed by a block argument. Which
+method receives the block argument?
+
+```ruby
+method_one method_two { |n|
+  puts "Executing a block: #{n}"
+}
+
+method_one method_two do |n|
+  puts "Executing a block: #{n}"
+end
+```
+
+In the first case, with the curly braces, `method_two` receives the block as an
+argument. In the second case, with the `do`/`end`, `method_one` receives the
+block as an argument.
