-# Verify Site Ownership With DNS Record
-
-To run your site through Google Search Console and get detailed reports, you
-need to verify that you own the site. There are several manual ways of doing
-this that involve sticking a value unique to your URL in a file or header tag.
-There is a better way though.
-
-By adding a TXT DNS record wherever you domain's DNS is managed, you can prove
-to Google that you own the domain. That verification applies to all paths and
-subdomains of that domain.
-
-Some providers like Cloudflare have a mostly-automated process for this that
-Google can hook into as long as you grant permission via OAuth.
-
-You can also manually create the TXT record if necessary.
-
-Either way, it will look something like:
-
-```bash
-$ dig -t TXT visualmode.dev

-;; ANSWER SECTION:
-visualmode.dev.         377     IN      TXT     "google-site-verification=MBZ2S2fhnh2gHRxFniRrYW-O6mdyimJDRFj-f

-# Fetch Specific Number Of Results
-
-If you pull up just about any intro to PostgreSQL (or even SQL), one of the
-first things they are going to teach you is the `limit` clause. This is taught
-as _the_ way for limiting the result set to a specific number of rows.
-
-```sql
-> select title from books limit 4;
-+-----------------------+
-| title                 |
-|-----------------------|
-| The Secret History    |
-| A Gentleman in Moscow |
-| Exhalation: Stores    |
-| Annihilation          |
-+-----------------------+
-SELECT 4
-```
-
-You might be as surprised as I was to learn that `limit` is not part of the SQL
-standard. It is extremely common for this use case, but the SQL standard
-defines `fetch first N rows only` as the way to fetch a specific number of
-rows. As we can see, [it works identically to `limit
-N`](https://www.postgresql.org/docs/current/sql-select.html#SQL-LIMIT).
-
-```sql
-> select title from books fetch first 4 rows only;
-+-----------------------+
-| title                 |
-|-----------------------|
-| The Secret History    |
-| A Gentleman in Moscow |
-| Exhalation: Stores    |
-| Annihilation          |
-+-----------------------+
-SELECT 4
-```
-
-The `rows` and `row` keywords are interchangeable which makes statements more
-readable if, for instance, you're doing `... fetch first 1 row only`.

-# 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.

-# Gather Positional Arguments In Method Definition
-
-The `*` symbol can be used in Ruby in a method definition to gather up an

-
-For instance, we can gather all positional arguments with this method
-definition:
-
-```ruby
-def gather_all(*args)
-  puts args
-end

-
-Or we can isolate the first positional arg and then gather the rest:
-
-```ruby
-def first_and_rest(first, *rest)
-  puts "First: #{first}, Rest: #{rest}"
-end
-```
-
-We can even do something a bit more interesting like isolating the first and
-last arguments while gathering up everything else in the middle:
-
-```ruby
-def pop_parens(left, *middle, right)
-  if left != '(' || right != ')'
-    raise "Uh oh!"
-  else
-    if middle.size == 1
-      puts "Found: #{middle.first}"
-    else
-      pop_parens(*middle)
-    end
-  end
-end
-```
-
-Here is what it looks like if we splat some different sets of arguments into
-that method call:
-
-```ruby
-> tokens1 = "((((4))))".split('')
-=> ["(", "(", "(", "(", "4", ")", ")", ")", ")"]
-> tokens2 = "((4))))".split('')

-# Stack Heredocs In A Method Call
-
-When you put a heredoc directly in a method call as an argument, it is only the
-opening identifier that goes in the argument list.
-
-That looks like this:
-
-```ruby
-execute_in_transaction(<<~SQL)
-  update reading_statuses
-  set status = 'abandoned'
-  where started_at < (now() - '2 years'::interval)
-    and finished_at is null;
-SQL
-```
-
-You might imagine then that we can put multiple heredocs in a method call. That
-leads to [_stacked
-heredocs_](https://www.visualmode.dev/ruby-operators/heredoc#stacked-heredocs).
-
-```ruby
-execute_in_transaction(<<~SQL1, <<~SQL2, <<~SQL3)
-  update reading_statuses
-  set status = 'abandoned'
-  where started_at < (now() - '2 years'::interval)

-SQL1
-  insert into activity_log (name, description)
-  values ('abandon_books', 'Mark unread books as abandoned');
-SQL2
-  delete from background_jobs
-  where id = #{job_id}; -- better to sanitize values like this
-SQL3

-Notice we terminate the body of each heredoc with its closing identifier and
-immediately begin the body of the next one.

-# Type Fewer Paths With Brace Expansion
-
-Bash has a feature called _brace expansion_ that allows us to do a kind of
-shorthand when writing out file paths. We can specify multiple variants
-comma-separated between curly braces and they'll each be expanded into separate
-arguments.
-
-It's easier to understand this by seeing it. If we type the following (don't
-hit `Enter` yet):
-
-```bash
-$ mkdir src/{one,two,three}
-```
-
-And then hit _Tab_:
-
-```bash
-$ mkdir src/one src/two src/three
-```
-
-Bash uses the portion in braces to expand into separate arguments. The part
-outside the braces gets reused for each. That's where we get some savings from
-typing out the same path each time.
-
-Here is another example where we use `mv` to rename a file deeply nested in our
-project:
-
-```bash
-$ mv projects/project1/src/app/utils/{names,constants}.js
-```
-
-We don't even have to _Tab_ it out. We can hit _Enter_ directly and `mv` gets
-both arguments.
-
-Similarly, how about we change the extension of our renamed file:
-
-```bash
-$ mv projects/project1/src/app/utils/constants.{js,ts}
-```
-
-I've always found this feature most useful with paths and filenames, but you
-can do brace expansion with any arguments.
-
-```bash
-$ echo 1{3,1,6,4,9,2,7,5}
-13 11 16 14 19 12 17 15

-# Synchronize Vim Clipboard With System Clipboard
-
-When I use Vim-mode in VSCode, I _yank_ text onto the Vim clipboard by visually
-selecting some text and hitting `y`. Then I can move the cursor somewhere else
-in the file (or another file in VSCode) and _paste_ it by hitting `p`.
-
-But what if I want the thing I yanked from a file to be pasted into another
-program, like Chrome? Or if I've copied some text from another program and I
-want to paste it into a file in VSCode?
-
-This cross-program copy and pasting is what the _system clipboard_ on your
-operating system is for. By default, the Vim clipboard is separate from the
-system clipboard. I personally prefer for them to be one and the same.
-
-To achieve this, I added the following line to my VSCode config in
-`settings.json`:
-
-```json
-{
-  "vim.useSystemClipboard": true
-}
-```
-
-It takes a little getting used to having them integrated, but I've done it for
-so long that it is muscle memory. It's hard to not have them integrated now.
-It's even better when I have a clipboard history tool like Raycast available
-for accessing past clipboard values.
