+# List RDS Snapshots With Matching Identifier Prefix
+
+I'm working on a script that manually creates a snapshot which it will then
+restore to a temporary database that I can scrub and dump. The snapshots that
+this script takes are _manual_ and they are named with identifiers that have a
+defining prefix (`dev-snapshot-`). Besides the few snapshots created by this
+script, there are tons of automated snapshots that RDS creates for
+backup/recovery purposes.
+
+I want to list any snapshots that have been created by the script. I can do
+this with the `describe-db-snapshots` command and some filters.
+
+```bash
+$ aws rds describe-db-snapshots \

+```
+
+There are two key pieces. The `--snapshot-type manual` filter excludes all
+those automated snapshots. The `--query` both filters to any snapshots whose
+identifier `?starts_with` the prefix `dev-snapshot-` and then refines the
+output to just the `DBSnapshotIdentifier` instead of the entire JSON object.

+
+Second, if you are using a `Brewfile` to manage what `brew` installs, then you
+can instruct `brew` to uninstall any dependencies that aren't specified in that
+file.
+
+By default it operates as a dry run and the `--force` flag will be needed to
+actually do the cleanup. And specify the filename if it doesn't match the
+default of `Brewfile`.
+
+```bash
+$ brew bundle cleanup --file=Brewfile.personal

+
+If the output looks good, then force the cleanup:
+
+```bash
+$ brew bundle cleanup --force --file=Brewfile.personal

+# Determine Absolute Path Of Top-Level Project Directory

+kinds of things in git into a canonical form that can be used in a deterministic
+way by scripts. I would typically think of using it to work with branch names,
+tags, and other kinds of refs.
+
+There is a handy, sorta off-label use for it in determining the absolute path of
+the root directory for the current git repository. Use the `--show-toplevel`
+flag with no other arguments.
+
+```bash
+❯ git rev-parse --show-toplevel
+/Users/lastword/dev/jbranchaud/til
+```
+
+Here, I am in the local copy of [my TIL repo](https://github.com/jbranchaud/til). This command gives me the absolute
+path of the top-level directory where that `.git` directory resides.
+
+This is useful for scripts that need to orient themselves to the current
+project's top-level directory regardless of what directory they are being
+executed from. This is useful for things like a git hook script or monorepos
+with scripts located in a specific sub-project directory.
+
+Also worth mentioning is the `--show-superproject-working-tree` flag. In my TIL
+repo, I have a private repository included as a submodule. Within that directory
+`--show-toplevel` will produce the absolute path to the submodule. If I instead
+want the absolute path of the _super project_ (in this case TIL), then I can use
+this other flag.

+# Exclude A Directory During A Command

+Many of the git commands we use, such as `git add`, `git restore`, etc., target
+files and paths relative to the current directory. This is typically exactly
+what we want, to stage and unstage and so forth the files and directories in
+front of us.
+
+I recently ran into a situation where I needed to restore a small subset of
+changes. At the same time, I had a massive number of auto-generated files
+recording HTTP interactions (hundreds of files, modified on the working tree).
+I wanted to run a `git restore`, but wading through all those HTTP recording
+files was not feasible.
+
+I needed to exclude those files. They all belonged to a `spec/cassettes`
+directory. I could exclude them with a _pathspec_ magic signature pattern which
+is used to alter and limit the paths in a git command.
+
+A _pathspec_ magic signature is a special pattern made up of a `:` followed by
+some signature declaring what the pattern means.
+
+The `(exclude)`, `!`, and `^` magic signatures all mean the same thing —
+exclude. So, we can exclude a directory from a `git restore` command like so:
+
+```bash
+$ git restore --patch -- . ':!spec/cassettes'
+```
+
+We've employed two pathspec patterns here. The first, `.`, scopes everything to
+the current directory. The second, `':!spec/cassettes'` excludes everything in
+the `spec/cassettes` directory.
+
+See `man gitglossary` for more on _pathspecs_.

+# Highlight Small Change On Single Line

+Sometimes a change gets made on a single, long line of text in a Git tracked

+looking at the diff. A standard diff will show a green line of text stacked on
+a red line of text with no more granular information.
+
+There are two ways we can improve the diff output in these situations.
+
+The first is built-in to git. It is the `--word-diff` flag which will visually
+isolate the portions of the line that have changed.
+
+```bash
+git diff --word-diff README.md

+
+Which will produce something like this:

+A collection of concise write-ups on small things I learn [-day to day-]{+day-to-day+} across a
+```
+
+The outgoing part is wrapped in `[-...-]` and the incoming part is wrapped in
+`{+...+}`.
+
+The second (and my preference) is to use
+[`delta`](https://github.com/dandavison/delta) as an external differ and pager
+for git.
+
+```bash
+git -c core.pager=delta diff README.md
+```
+
+I cannot visually demonstrate the difference in a standard code block. So I'll
+describe it. We see a red and green line stacked on each other, but with muted
+background colors. Then the specific characters that are different stand out
+because they are highlighted with brighter red and green. I [posted a visual
+here](https://bsky.app/profile/jbranchaud.bsky.social/post/3ln245orlxs2j).

+# Show Summary Stats For Current Branch
+
+When I push a branch up to GitHub as a PR, there is a part of the UI that shows
+you how many lines you've added and removed for this branch. It bases that off
+the target branch which is typically your `main` branch.
+
+The `git diff` command can provide those same stats right in the terminal. The
+key is to specify the `--shortstat` flag which tells `git` to exclude other diff
+output and only show:
+
+- Number of files changed
+- Number of insertions
+- Number of deletions
+
+Here is the summary stats for a branch I'm working on:
+
+```bash
+❯ git diff --shortstat main
+ 8 files changed, 773 insertions(+), 25 deletions(-)
+```
+
+We have to be on our feature branch and then we point to the branch (or whatever
+ref) we want to diff against. Since I want to know how my feature branch
+compares to `main`, I specify that.

+# Format A List Of Items By Locale

+The `Intl` module includes a [`ListFormat`
+object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/ListFormat)
+which can be used to format a list of items in a consistent way across locales.
+
+I've reinvented the wheel of writing a helper function numerous times across
+projects for formatting a list of items that accounts for formatting based on
+how many items there are. This built-in function handles that with the added
+benefit of working across locales.
+
+Here are lists of three, two, and one items formatted in the `long` styles for
+US english.
+
+```javascript
+> const formatter = new Intl.ListFormat('en', { style: 'long', type: 'conjunction' });

+> formatter.format(['Alice', 'Bob', 'Carla'])
+'Alice, Bob, and Carla'
+
+> formatter.format(['Coffee', 'Tea'])
+'Coffee and Tea'
+
+> formatter.format(['Taco'])
+'Taco'
+```
+
+The difference between `long` and `short` style for a `conjunction` is _and_
+versus _&_. In addition to the type`conjunction`, you could also use
+`disjunction` which will do an _or_ instead of an _and_. I'm not sure what
+you'd use the `unit` type for.
+
+You could use another locale, such as French, as well:
+
+```javascript

+
+> formatter.format(['café', 'thé'])

+
+```bash

+That value is the number of nanoseconds since a human input device was last
+interacted with. That is the amount of time the user (me) has been idle.

+$ ioreg -c IOHIDSystem | awk '/HIDIdleTime/ {printf "%.2f seconds\n", $NF/1000000000}'

+# Get Idea Of What Is In A JSON Column
+
+While digging through some data trying to reacquaint myself with the overall
+schema and data model, I ran into an issue selecting rows from this
+`content_resource` table. There was so much text packed in to the `"body"`,
+`"summary"`, and `"description"` key-value pairs of `fields` JSON column that a
+simple `select * ... limit 3;` was overwhelming the screen with text and table
+formatting characters (i.e. `+------+-------`).
+
+I figured the `fields` JSON followed a reliable structure, at least for records
+of the same `type`. So, let's start by only grabbing the
+[`json_keys`](https://dev.mysql.com/doc/refman/8.4/en/json-search-functions.html#function_json-keys)
+so that I can get a sense of the shape of the JSON.
+
+```sql
+select id, json_keys(fields)
+from content_resource
+where type = 'post'
+limit 3;
+
++-----+-----------------------------------------------------------------------------------------------------------+
+| id  | json_keys(`fields`)                                                                                       |
++-----+-----------------------------------------------------------------------------------------------------------+
+|  1  | ["body", "slug", "state", "title", "summary", "postType", "visibility", "description", "originalLessonId"] |
+|  2  | ["body", "slug", "state", "title", "summary", "postType", "visibility", "description", "originalLessonId"] |
+|  3  | ["body", "slug", "state", "title", "summary", "postType", "visibility", "description", "originalLessonId"] |
++-----+-----------------------------------------------------------------------------------------------------------+
+```
+
+For the `post` type, I see the same keys for this sampling of rows. Now I have
+an idea what keys are present and can start digging in further.
+
+My next query might look something like this:
+
+```sql
+select id, fields->'$.slug', fields->'$.title', fields->'$.state'
+from content_resource
+where type = 'post'
+limit 3;

+# Jump Between Changes In Current File
+
+With the [gitsigns.nvim plugin](https://github.com/lewis6991/gitsigns.nvim) for
+Neovim, I get some handy Git-related capabilities like gutter highlighting of
+additions, deletions, and changes to lines in the current file. These contiguous
+sections of modification to the versioned state of a file are called hunks.
+
+Here are two mappings (in Lua) for gitsigns that allow me to jump to the next
+(`]h`) or previous (`[h`) hunk in the current file.
+
+```lua
+---@type LazyKeysSpec[]

+is a variation of the [`\g`
+meta-command](https://www.postgresql.org/docs/current/app-psql.html#APP-PSQL-META-COMMAND-G),

+executes each row of the result as its own SQL statement.
+
+This is both a bit absurd and powerful. And a bit unnecessary considering all
+of the scripting capabilities with anything from bash to any language with a
+SQL client library.
+
+Nevertheless, let's take a look at a contrived example of how it works. Here,
+we have a SQL statement that does some string concatenation based off values in
+an array. This results in three separate `create schema` statements.

+Then select the Postgres version. My existing project is still on 17, so I'll
+select that.
+
+The not so intuitive part is the _Data Directory_. Use the "Choose..." file
+picker to find the root directory of your project. Select that. Then click into

+_to be created_ to that path. If I want it to all go in `postgres-data`, then my

+# Filter ActiveModel Validation Errors

+Now that `ActiveModel` has a custom `Errors` class (as of Rails 6.1) instead of
+a hash, we get some useful functionality. Namely, we get a [`#where`

+that allows us to filter errors based on the attribute name, type of
+validation, and even properties of that validation.
+
+Here I have created a new `Book` without any attributes. All of its validations
+are going to fail and we are going to have an `ActiveModel::Errors` object
+attached to it with several errors.
+
+```ruby
+> book = Book.new

+#<Book:0x00000001110397a8
+...

+```
+
+Let's say I want to check for a specific validation error. I can use `#where`
+to filter down by attribute name (e.g. `:title`). I can filter even further by
+including the validation type as well (e.g. `:too_short`).
+
+```ruby
+> book.errors.where(:title)
+=>
+[#<ActiveModel::Error attribute=title, type=blank, options={}>,
+ #<ActiveModel::Error attribute=title, type=too_short, options={:count=>3}>]

+=> "is too short (minimum is 3 characters)"
+> book.errors.where(:title, :too_short).first.full_message
+=> "Title is too short (minimum is 3 characters)"
+```
+
+This filtering could be used as part of conditional checks for what flash
+message gets displayed to the user or even what route/view gets rendered in
+response to the error.

+Modern versions of Rails and ActiveRecord have [an `upsert`
+method](https://api.rubyonrails.org/v8.0.2/classes/ActiveRecord/Relation.html#method-i-upsert)
+which will, if available, use your database's upsert capability to either
+insert a new row or update an existing row based on the unique identifier.
+
+The docs have the following disclaimer:
+
+> It does not instantiate any models nor does it trigger Active Record
+> callbacks or validations. Though passed values go through Active Record’s
+> type casting and serialization.
+
+It's a bit different to work with than other ActiveRecord methods. It left me
+wondering if it would handle timestamp management or if I would have to do that
+myself.
+
+Let's upsert a new record into `books`:
+
+```ruby
+> Book.upsert({title: "Shogun", author: "James Clavell", added_by_id: 1, publication_date: Date.today}, unique_by: :id)
+=> #<ActiveRecord::Result:0x00000001141c3df0 ...

+```
+
+Notice that the `created_at` and `updated_at` timestamps get set.
+
+Now, let's upsert the record (notice we're passing in the `id`) to update the title with an `ō`.
+
+```ruby
+> Book.upsert({id: 12, title: "Shōgun", author: "James Clavell", added_by_id: 1, publication_date: Date.today}, unique_by: :id)
+=> #<ActiveRecord::Result:0x0000000113cace98 ...

+```
+
+Notice that the `updated_at` gets set to a time about 2 minutes later.
+
+Lastly let's look at the `record_timestamps` option. This is `nil` by default
+which means the underlying methods default kicks in which _is_ to record the
+timestamps. We can override that behavior by passing in `false`.
+
+```ruby
+> Book.upsert({id: 12, title: "Shōgun, Part 2", author: "James Clavell", added_by_id: 1, publication_date: Date.today}, unique_by: :id, record_timestamps: false)

+```
+
+Notice that the `updated_at` value doesn't change between this upsert and the
+previous upsert.

+# Parameterize A String With Underscores
+
+I have human-readable status strings that I'm working with like `In progress`,
+`Pending approval`, and `Completed`. I need to deterministically turn those
+into parameterized values that I can compare. That is, I want them lowercased
+and separated by underscores instead of spaces.
+
+The `ActiveSupport` `#parameterize` method, as is, gets me pretty close.
+
+```ruby
+> statuses = [
+  "In progress",
+  "Pending approval",
+  "Completed"
+]
+
+> statuses.map(&:parameterize)
+=> [
+  "in-progress",
+  "pending-approval",
+  "completed"
+]
+```
+
+Those are separated by dashes though. Fortunately, `parameterize` takes a
+`separator` option that we can use to verride what character is used to
+separate words. Let's use an underscore (`_`).
+
+```ruby
+> statuses.map { |str| str.parameterize(separator: '_') }
+=> [
+  "in_progress",
+  "pending_approval",
+  "completed"
+]

+docs](https://api.rubyonrails.org/classes/ActiveSupport/Inflector.html#method-i-parameterize)

+# Prevent Mailer Previews From Cluttering Database
+
+ActionMailer Previews give you a way to view email templates that your system
+sends. This is how I check that it is styled properly and that the logic and
+data of the template are able to run and render.
+
+Data for a preview typically means we need ActiveRecord objects and even their
+associations. If we start creating one-off records in our previews either with
+`#create` or with something like `FactoryBot`, those records will get left
+behind in our development database. Every view and refresh of a preview will
+generate more of these records.
+
+One way to get around that is to use `#new` and `#build`. I've found this
+cumbersome and it often leaves assocations missing or inaccessible.
+
+What if instead the preview could clean up after itself? That sounds like a
+great job for a database transaction.
+
+Let's create a `test/mailers/previews/base_preview.rb` as a base class for all
+our preview classes.
+
+```ruby
+class BasePreview < ActionMailer::Preview
+  def self.call(...)
+    message = nil
+    ActiveRecord::Base.transaction do
+      message = super(...)
+      raise ActiveRecord::Rollback
+    end
+    message
+  end
+end
+```
+
+This wraps the existing `self.call` functionality in a transaction that
+collects the resulting message from the preview and then rolls back the
+database changes.
+
+Now, instead of our individual preview classes inheriting directly from
+`ActionMailer::Preview`, they can inherit from `BasePreview`.
+
+```ruby
+class UserMailer < BasePreview
+
+  # ...
+
+end
+```

+# Provide Fake Form Helper To Controllers
+
+I'm rendering a partial from a turbo stream. The partial is meant to be

+that is streaming the partial, there is no
+[FormBuilder](https://api.rubyonrails.org/v6.1.0/classes/ActionView/Helpers/FormBuilder.html)
+object.
+
+One way to get around this that I've borrowed from [Justin
+Searls](https://justin.searls.co/posts/instantiate-a-custom-rails-formbuilder-without-using-form_with/)
+is with a `FauxFormHelper`.
+
+```ruby

+
+This module defines and exposes a `faux_form` object that controllers and views
+can access. Then my partial can recieve that form object as a parameter.

+# Run Dev Processes With Overmind Instead Of Foreman
+
+Most Rails projects that I have worked on have used
+[`foreman`](https://github.com/ddollar/foreman) as a development dependency for
+running all the processes declared in your Procfile (`Procfile.dev`). As far as
+having a single command to run everything (Rails server, asset building,
+worker(s), etc.), it does the job.
+
+`foreman` has some serious points of friction though. The one that really stands
+out to me is that when I try to debug the development Rails server with
+`binding.irb` or `binding.pry`, the other processes tend to interfere.
+
+The alternative to `foreman` that I've been trying out recently is
+[`overmind`](https://github.com/DarthSim/overmind). A specific selling point of
+`overmind` is that it runs all the development processes in a `tmux` session.
+That means you can individually connect to, inspect, and restart each process.
+
+Once you've installed `overmind` (`brew install overmind`), then you can easily
+swap it in for `foreman` like so:
+
+```bash
+$ overmind start -f Procfile.dev
+```
+
+You can connect to any of those processes directly:
+
+```bash
+$ overmind connect sidekiq
+```
+
+When you want to `binding.irb` the Rails server, you can specifically connect to
+the `web` process to do that.
+
+```bash
+$ overmind connect web
+```
+
+If you need to stop all the process, you can run the `kill` subcommand.
+
+```bash
+$ overmind kill
+```
+
+Lastly, if you have a `bin/dev` script in your project, it is probably using
+`foreman`. If you and your team prefer `overmind`, then update that script
+accordingly and you can simply run `bin/dev` going forward.

+# Run Rails Console With Remote Dokku App
+
+Whenever I want to `rails console` into the _staging_ server of an app I'm
+working on, I first have to `ssh` into server and then I have to come up with
+the [`dokku`](https://dokku.com/) command to run `rails console` against the app
+on that server.
+
+```bash
+local> ssh app-staging # app-staging is an SSH alias
+staging> dokku run my-app rails console
+```
+
+I figured out how to reduce the friction of this by collapsing it into a single
+command that I can run locally. I can remotely run the `dokku` command with
+`ssh` using an interactive session (`-t`).
+
+```bash
+local> ssh -t app-staging dokku run my-app rails console
+```
+
+That will open up a `rails console` session directly in the current shell
+session via a remote SSH connection. The `-t` flag is important because that
+makes the session interactive so that I can interact with the REPL.
+
+I've even packaged this up into a bin script (`bin/staging-console`) with a
+couple checks to enhance the DX. I won't put the whole thing here, but the gist

+# Scope Records To A Lower Or Upper Bound
+
+Typically when we use
+[`#where`](https://api.rubyonrails.org/classes/ActiveRecord/QueryMethods.html#method-i-where)
+to scope queries against ActiveRecord models, we are looking to do a direct
+"equals" comparison.
+
+Such as `auth_codes.user_id = 1` in the example below.
+
+```ruby
+> AuthCode.where(user_id: 1)
+  AuthCode Load (0.4ms)  SELECT "auth_codes".* FROM "auth_codes" WHERE "auth_codes"."user_id" = 1 /* loading for pp */ LIMIT 11
+```
+
+We can do more powerful things with `#where` (assuming your database supports
+it, in my case PostgreSQL), such as comparing over ranges of dates. Ruby's
+range syntax gives us an elegant way to express ranges.
+
+```ruby
+> 2..10 # range with lower bound of 2 and upper bound of 10
+
+> 2.. # 'end'less range
+
+> ..10 # 'begin'less range
+```
+
+These latter two examples are ranges that are unbounded on one side or the
+other. We can use these in ActiveRecord `#where` queries to do "greater than or
+equal to" and "less than or equal to" conditionals.
+
+And we can do the same with ranges of dates like in the following queries.
+
+
+```ruby
+> AuthCode.where(created_at: 10.days.ago..).count
+  AuthCode Count (97.1ms)  SELECT COUNT(*) FROM "auth_codes" WHERE "auth_codes"."created_at" >= '2025-09-24 00:35:46.937715'
+
+> AuthCode.where(created_at: 10.days.ago..5.days.ago).count
+  AuthCode Count (0.6ms)  SELECT COUNT(*) FROM "auth_codes" WHERE "auth_codes"."created_at" BETWEEN '2025-09-24 00:35:59.901441' AND '2025-09-29 00:35:59.901512'
+
+> AuthCode.where(created_at: ..5.days.ago).count
+  AuthCode Count (0.3ms)  SELECT COUNT(*) FROM "auth_codes" WHERE "auth_codes"."created_at" <= '2025-09-29 00:36:09.731444'
+```
+
+Notice in the generated SQL how the simple `#where` method gets transformed
+into a `>=`, a `<=`, or a `between` clause.
+
+And while dates are a powerful example of this, there is nothing to stop us
+from querying against other kinds of ranges like numeric ones.
+
+```ruby
+# Orders under $10
+ten_dollars_in_cents = 10 * 100
+Order.where.not(fulfilled_at: nil).where(amount: ..ten_dollars_in_cents)

+# Use .ruby Extension For Template File
+
+An interesting feature of Rails that I can't seem to find documented anywhere is
+that you can write a template file with plain Ruby by using the `.ruby`
+extension. For instance, you might want to render some JSON from a template.
+Instead of using `jbuilder` or `erb`, you can have a `show.json.ruby` file. This
+is also popular with Turbo Stream files -- e.g. `update.turbo_stream.ruby`.
+
+How this works is that the entire file is evaluated as if it were a `.rb` file.
+Then the return value of the final statement is what is returned and rendered by
+Rails.
+
+```ruby
+author_byline = @book.authors.map(&:name).to_sentence
+
+data = {
+  id: @book.id,
+  title: @book.title,
+  author: author_byline,
+  status: @book.published_at > Time.current ? 'Coming Soon' : 'Published',
+  publication_year: @book.published_at.year
+}
+
+data.to_json
+```
+
+That final line converts the hash of data that we've built up into a JSON string
+that can then be rendered by the controller action that corresponds to this view
+template.
+
+Similarly, you can have a Turbo Stream template `show.turbo_stream.ruby` that
+looks something like this:
+
+```ruby
+[
+  turbo_stream.prepend("posts", @post),
+  turbo_stream.update("form", partial: "form", locals: { post: Post.new })
+].join
+```
+
+This template file is made up of a single statement which is an array of turbo
+stream results that get joined together.

+I went into full detail about how the [`Module#module_function` method](https://ruby-doc.org/3.4.1/Module.html#method-i-module_function) works.
+It creates both a module of utility functions that we can access directly on
+that module like we would with `self` methods. It can also be included in a
+class as a way of sharing copies of those utility functions with the class. A
+key point to them being copies is that they can then be overridden by the
+including class.
+
+Here is the example I used in the blog post:
+
+```ruby
+module MarkdownHelpers

+  def heading(text, level = 1)
+    ("#" * level) + " #{text}"

+  end
+end
+```
+
+I won't cover everything that the blog post covers, but what I found really nice
+about this pattern is that I can call those utility functions directly with the
+module as the receiver:
+
+```bash
+$ ruby -r ./markdown_helpers.rb -e 'puts MarkdownHelpers.link("Click here", "https://example.com")'
+[Click here](https://example.com)

+  end
+
+  def self.image(alt_text, href)
+    "!#{link(alt_text, href)}"

+That would be fine, but we completely lose out on the ability to include it as a

+Now, any test that is exercising behavior that uses those parts of the

+
+The above class always is successful when `send_sms_message` is called. What if

+Let's create a helper that can create `MockTwilioClient` instances, either as is

+```ruby
+def create_mock_twilio_client(&block)

+    Class.new(MockTwilioClient, &block).new
+  else

+  end

+```
+
+If we pass it a block with specific method overrides, it will create a one-off
+anonymous subclass of `MockTwilioClient` with that block which effectively
+overrides the parent class's methods.
+
+We can put this to use like so:
+
+```ruby

+      # some assertions ...

+
+In the second test case, I override the _success path_ with a version of

+# Decompose Unicode Character With Diacritic Mark

+A character like the `ñ` is typically represented by the unicode codepoint of
+`U+00F1`. However, it is also possible to represent it with two unicode
+codepoints -- the `n` (`U+006E`) and the combining diacritical mark `˜`
+(`U+0303`).
+
+We can see that by comparing a typed `ñ` with one where we split it apart into
+the separate codepoints. We can do that with
+[`#unicode_normalize`](https://apidock.com/ruby/v2_5_5/String/unicode_normalize)
+and the `:nfd` argument which stands for _Normalized Form Decomposed_.

+=> false
+> "ñ".unicode_normalize(:nfd).length
+=> 2
+> "ñ".length
+=> 1
+```
+
+We can inspect the exact codepoints by iterating over each character and
+printing out the codepoint value.
+
+```ruby
+"ñ".each_char.with_index do |char, i|
+  puts "#{i}: '#{char}' -> U+#{char.ord.to_s(16).upcase.rjust(4, '0')}"

+# 0: 'n' -> U+006E
+# 1: '̃' -> U+0303
+#=> "ñ"
+```
+
+Notice the difference after the character has been decomposed such that the
+diacritic is separated from the character.
+
+This can be done with other characters containing diacritics.
+
+And here we go the other direction with
+[`#pack`](https://ruby-doc.org/core-3.0.1/Array.html#method-i-pack).

+define its own dependencies.
+
+Require `"bundler/inline"` and then add a `gemfile` block toward the top of the

+# Join URI Path Parts
+
+The
+[`URI.join`](https://ruby-doc.org/stdlib-2.5.1/libdoc/uri/rdoc/URI.html#method-c-join)
+method seems like a handy way to combine a base URL with some subpath. However,
+there are some subtle gotchas depending on where forward slashes appear in the
+two arguments.
+
+Let's first look at the, in my opinion, desired behavior:
+
+```ruby
+> URI.join("https://example.com/api/v1/", "users")
+=> #<URI::HTTPS https://example.com/api/v1/users>
+```
+
+The base URL has a trailing slash and the path that I want to join to it has no
+leading slash. The result is a path where `users` is joined to the end of the
+base URL. That's what I'm looking for.
+
+Now, let's see some variations on the above approach that give results that I
+wasn't expecting and don't want.
+
+```ruby
+> URI.join("https://example.com/api/v1", "/users") # 1
+=> #<URI::HTTPS https://example.com/users>
+> URI.join("https://example.com/api/v1", "users") # 2
+=> #<URI::HTTPS https://example.com/api/users>
+> URI.join("https://example.com/api/v1/", "/users") # 3
+=> #<URI::HTTPS https://example.com/users>
+```
+
+1. No trailing slash on the base URL. Leading slash on the path to join. The
+   path portion of the base URL is wiped out and `/users` is joined in.
+2. No trailing slash on the base URL. No leading slash on the path to join. The
+   `users` path replaces the last part of the path in the base URL.
+3. Both a trailing slash in the base URL and a leading slash in the path to
+   join. Same behavior as 1.
+
+I have two takeaways from this:
+- Use with caution. If I'm going to use `URI.join` for this purpose, I need to
+  be careful to only use the form in the first code block.
+- The `URI.join` method is probably meant to be primarily used to join a domain
+  (e.g. `http://example.com`) that has no path with some path segment.

+# Make Structs Easier To Use With Keyword Initialization
+
+Typically a [`Struct`](https://ruby-doc.org/3.4.1/Struct.html#method-c-new) in
+Ruby is defined and initialized like so:
+
+```ruby
+> Subscriber = Struct.new(:email, :first_name, :status, :tags)
+=> Subscriber
+> s1 = Subscriber.new('bob.burgers@example.com', 'Bob', :active, [:food, :family])
+=> #<struct Subscriber email="bob.burgers@example.com", first_name="Bob", status=:active, tags=[:food, :family]>
+> s1.email
+=> "bob.burgers@example.com"
+```
+
+That's a nice way to structure light-weight objects.
+
+A potential challenge with multi-argument `Struct` definitions like this,
+especially when they aren't colocated with initialization, is that it can be
+hard to remember or distinguish the argument order when initializing an instance
+of one.
+
+Ruby 2.5 added the `keyword_init` option to help with this exact issue. When
+that option is set to `true` for a `Struct` definition, then we get to
+initialize it with keyword arguments rather than positional arguments.
+
+```ruby
+> Subscriber = Struct.new(:email, :first_name, :status, :tags, keyword_init: true)
+=> Subscriber(keyword_init: true)
+* s1 = Subscriber.new(
+*   first_name: 'Bob',
+*   email: 'bob.burgers@example.com',
+*   tags: [:food, :family],
+*   status: :active
+> )
+=> #<struct Subscriber email="bob.burgers@example.com", first_name="Bob", status=:active, tags=[:food, :family]>
+> s1.email
+=> "bob.burgers@example.com"
+```
+
+Notice I have to use keyword arguments now and that because of that I can
+organize them in whatever order makes sense. Coming back to view this line of
+code later, it is easy to see attribute each value corresponds to.

+# Disable And Enable A Button
+
+With TailwindCSS we can take a couple different approaches to tie the visual
+and functional interactivity of a button to another elements state using
+classes.
+
+One approach is to use
+[`peer`](https://tailwindcss.com/docs/hover-focus-and-other-states#styling-based-on-sibling-state)
+and `peer-checked:<class>`.
+
+```html
+<div>
+  <input
+    type="checkbox"
+    id="peer-enable"
+    class="w-5 h-5 cursor-pointer peer"
+  />
+  <label
+    for="peer-enable"
+    class="cursor-pointer text-slate-700 font-medium"
+  >
+    I agree to the terms and conditions
+  </label>
+  <button
+    class="opacity-40 pointer-events-none grayscale cursor-not-allowed peer-checked:opacity-100 peer-checked:pointer-events-auto peer-checked:grayscale-0 peer-checked:cursor-pointer"
+  >
+    Peer Submit
+  </button>
+</div>
+```
+
+Classes to make to button appear disabled (e.g. `opacity-40`) as well as
+functional classes that affect interactivity (e.g. `pointer-events-none`) are
+applied by default. When the sibling checkbox gets checked, the inverted
+classes take effect making the button enabled.
+
+The `peer` approach works, but lacks flexibility. As soon as I need to make any
+structural changes to the HTML that sever the peer (i.e. sibling) relationship
+of the checkbox and the button, those classes stop working.
+
+With
+[`group`](https://tailwindcss.com/docs/hover-focus-and-other-states#styling-based-on-the-descendants-of-a-group)
+and `group-has-[:checked]:<class>`, I can style the button relative to another
+group member as long as everything is nested under some shared group tag.
+
+```html
+<div class="group">
+  <div class="flex items-center gap-3">
+    <input
+      type="checkbox"
+      id="group-enable"
+      class="w-5 h-5 cursor-pointer"
+    />
+    <label
+      for="group-enable"
+      class="cursor-pointer text-slate-700 font-medium"

+  >
+    Group Submit
+  </button>
+</div>
+```
+
+We can even utilize [named
+groups](https://tailwindcss.com/docs/hover-focus-and-other-states#differentiating-nested-groups)
+if we have overlapping and conflicting group interactions. But I won't get into
+that here.

+# Create Interactive Picker For Set Of Subtasks

+For [my TIL repo](https://github.com/jbranchaud/til), I have a `Taskfile.yml`
+that defines a set of `notes:*` tasks for interacting with a `NOTES.md` file
+that lives in a private Git submodule.
+
+I wanted to make it easier on myself to not have to remember all the different
+`notes` subtasks, so I created a helper task to make it easy to see the options
+and run one.
+
+A summary of the Taskfile is shown below including the entirety of the `notes`
+task. That task will parse a listing of the available tasks (via `task --list`
+and some `sed` commands) and pass those to `fzf` to provide an interactive
+picker of the available subtasks.
+
+```yaml
+tasks:
+  notes:
+    desc: Interactive picker for notes tasks
+    cmds:
+      - |
+        TASK=$(task --list | grep "^\* notes:" | sed 's/^\* notes://' | sed 's/\s\+/ - /' | fzf --prompt="Select notes task: " --height=40% --reverse) || true

+
+  notes:pull:
+    ...
+
+  notes:diff:
+    ...
+
+  notes:log:
+    ...
+```
+
+Now I can run the `notes` task to get a summary and interactive picker that
+looks like the following:
+
+```sh
+❯ task notes
+Select notes task: 
+  9/9
+> │                    Interactive picker for notes tasks
+  diff:                Show uncommitted changes in notes
+  edit:                All-in-one edit, commit, and push notes
+  log:                 Show recent commit history for notes
+  open:                Opens NOTES.md (syncs latest changes first) in default editor
+  pull:                Pull latest changes (alias for sync)
+  push:                Commit and push changes to notes submodule
+  status:              Check status of notes submodule
+  sync:                Sync latest changes from the notes submodule
+```
+
+It pulls in the subtask name and description. I can then use `fzf`'s navigation
+and filtering to narrow down and select the task I want to run.

+up-to-date or need to run the task.
+
+For instance, here is a `status` check that determines if there are changes to

+day_01
+day_02
+day_03
+day_04
+day_05

+The `%g` indicates that there is a format specifier for a numeric type which is
+where `seq` will inject the current value in the sequence. The `02` indicates
+that it should be `0` padded to `2` digits.
+
+We can then pipe this to another unix command, such as `mkdir` in order to
+quickly create a bunch of directories for, say, [Advent of Code](https://adventofcode.com/2024).

+# Have Script ShellCheck Itself When Executing
+
+The [ShellCheck](https://www.shellcheck.net/) utility can be run against bash
+scripts to check if there are any warnings or errors we should fix. It works
+great as long as we remember to run it.
+
+I wondered if I could make it easier on myself by not having to remember to run
+it. What if my bash script were to `shellcheck` itself?
+
+Here is an example script where at the beginning it looks for and runs the
+`shellcheck` utility against `$0` (the path of the script). This is kind of
+meta. As the script is executing, it has an external program run against the
+entire contents of itself. If there are any `shellcheck` issues, they get
+displayed and the program exits early.
+
+```bash
+#!/bin/bash
+
+# Exit immediately if any command fails
+set -e
+
+# Self-validation using ShellCheck
+if command -v shellcheck &> /dev/null; then
+    echo "Validating script with ShellCheck..."
+
+    # $0 refers to the script itself
+    if ! shellcheck "$0"; then
+        echo "ShellCheck found issues in the script. Exiting."
+        exit 1
+    fi
+    echo "Script validation passed."
+else
+    echo "Warning: ShellCheck not found. Skipping validation."

+echo "Script execution continuing..."

+# shellcheck warning here
+read -p "Continue with current operation? (yes/no): " CONTINUE_WITH_EXISTING
+if [[ ! "$CONTINUE_WITH_EXISTING" =~ ^[Yy][Ee][Ss]$ ]]; then
+    echo "Operation cancelled."
+    exit 1
+fi
+```
+
+This last bit of the script with the `read` command will trigger a warning from
+`shellcheck`.
+
+```bash
+$ ./check.sh
+Validating script with ShellCheck...
+
+In ./check.sh line 23:
+read -p "Continue with current operation? (yes/no): " CONTINUE_WITH_EXISTING

+# Interpret Cron Schedule From The CLI

+I encounter cron task schedules infrequently enough that I don't remember how
+to reliably interpret them at a glance. So when I'm looking over some code and
+I see something like `12 2,16 * * *`, I need to translate it to a
+human-readable format.
+
+I've typically opened up a browser tab to
+[crontab.guru](https://crontab.guru/#12_2,16_*_*_*) for this. However, I did
+just learn about a tool for getting the same information from the CLI.
+
+With the [`hcron`](https://github.com/lnquy/cron) binary, I can pass in a
+single cron schedule and get the same details right from my terminal.
+
+```bash
+$ hcron '12 2,16 * * *'
+12 2,16 * * *: At 02:12 AM and 04:12 PM

+place the `hcron` binary in my `~/bin` directory which is on my path. Once I

+# Make Neovim The Default Way To View Man Pages

+I was reading the help page for `:Man` which is the built-in plugin to Neovim
+for viewing man pages within a Neovim session. In it, they mentioned that the
+`MANPAGER` can be set to use Neovim instead of the default man page viewer.
+
+This can be done by setting `MANPAGER` like so:
+
+```bash
+$ export MANPAGER='nvim +Man!'
+```
+
+After setting this, you can run something like `man git-restore` which will
+open the man page for that command in a Neovim session using the Man page
+plugin which can do things like follow links to other man pages (`K` or
+`Ctrl=]`), quit by hitting `q`, as well as all the motions and search behavior
+of Vim.
+
+For long-term use, this can be set in your shell config, e.g. `~/.zshrc`. For
+one-off use, you can include it as an env var for a single call to `man`:
+
+```bash
+MANPAGER='nvim +Man!' man git-restore
+```
+
+See `:h :Man` within a Neovim session for more details.

+# Rename A Bunch Of Files By Constructing mv Commands
+
+I downloaded a bunch of bank statements as PDFs. On the upside they all were
+consistently named. On the downside they used an unhelpful date format. With a
+date format that puts year before month before day, the files easily sort
+alphanumerically. However, these filenames used a date format that put month
+before day before year.
+
+Here is a subset of the files
+
+```bash
+$ ls *.pdf
+'012524 Statement.pdf'
+'012725 Statement.pdf'
+'022624 Statement.pdf'
+'022625 Statement.pdf'
+'032524 Statement.pdf'
+'032525 Statement.pdf'
+```
+
+Notice they are named with `MMDDYY Statement.pdf`. I would instead like for them
+to be named as `YYYY-MM-DD-statement.pdf`.
+
+I can generate a series of `mv` statements that then get piped to `sh` which
+_evaluates_ them. But first, let's do a dry run of a `sed` statement that
+rearranges the date parts.
+
+```bash
+$ ls *.pdf | sed 's/\(..\)\(..\)\(..\) Statement\.pdf/mv "&" "20\3-\1-\2-statement.pdf"/'
+mv "012524 Statement.pdf" "2024-01-25-statement.pdf"
+mv "012725 Statement.pdf" "2025-01-27-statement.pdf"
+mv "022624 Statement.pdf" "2024-02-26-statement.pdf"
+mv "022625 Statement.pdf" "2025-02-26-statement.pdf"
+mv "032524 Statement.pdf" "2024-03-25-statement.pdf"
+mv "032525 Statement.pdf" "2025-03-25-statement.pdf"
+```
+
+The way this works is that all the `pdf` files in the current directly get
+listed out. That gets piped to a `sed` statement that matches on capture groups
+against the first three pairs of characters (the date parts) in the filenames.
+It matches on the rest of the filename (` Statement.pdf`). This is then replaced
+by a `mv `, the full match of the original filename (`&`), and then the new
+filename made up of the rearranged date parts.
+
+I can then pipe it to `sh` to run those `mv` commands.
+
+```bash
+$ ls *.pdf |
+  sed 's/\(..\)\(..\)\(..\) Statement\.pdf/mv "&" "20\3-\1-\2-statement.pdf"/' |
+  sh

+# Bypass On-Save Tooling When Writing File
+
+Every once in a while I run into an issue where my code formatters or linters
+are misconfigured for a project. I try to save a file and it applies formatting
+that I don't want. Or in an extreme case, the error ouput of the tool is what
+overwrites the file.
+
+I need to troubleshoot my dev tooling eventually, but I don't want to get
+sidetracked at the moment. I just want to save the file. What can I do?
+
+Tools like linters and code formatters are typically hooked up to Vim via
+autocommands on certain actions like `FileWrite*` or `BufWrite*`. We can
+execute a Vim command like writing a file (`w`) while disregarding autocommands
+like so:
+
+```vim
+:noautocmd w
+```
+
+or, write and quit:
+
+```vim
+:noautocmd wq
+```
+
+This disables all autocommands for this one command. The file gets saved and
+the misconfigured formatters and linters don't clobber the changes you
+intended.
+
+See `:h noautocmd` for more details.

+
+VSCode (as well as Cursor) supports this functionality as well. There are a
+couple ways to do it.
+
+First, from the File Browser sidebar you can right click on a particular file or
+directory. Find the _Open on Remote (Web)_ submenu. From there select _Open File
+on Remote_. That will open the file in GitHub with the focused line highlighted
+(or will open to that directory, as the case may be).
+
+Alternatively, you can right click in the file editor and follow the exact same
+steps as described above.
+
+If you're wanting a permalink to the remote that highlights a selection of
+lines, you can highlight that section of lines and right-click the selected
+lines and again follow the steps above.
+
+If your remote is some other host like BitBucket, it will recognize that from
+your project's gitconfig and open to that instead of GitHub.

+The [`watson` CLI utility](https://github.com/jazzband/Watson) is built to help
+track time across projects right from the terminal. It is written in Python and
+can be installed via `brew` or `pip3`.
+
+To start tracking a new or existing project, I can specify it by name like so:
+
+```bash
+$ watson start my-project +reporting
+Starting project my-project [reporting] at 00:28
+```
+
+This starts a timer for the `my-project` project and includes the tag
+`reporting`. Tags are optional but can give some context to what part of a given
+project this time session is for.
+
+At any point during a session, we can check the status.
+
+```bash
+$ watson status
+Project my-project [reporting] started 14 seconds ago (2025.11.14 00:28:31-0600)
+```
+
+And when we are done working on that project for the time being, we can stop it.
+
+```bash
+$ watson stop
+Stopping project my-project [reporting], started a minute ago and stopped just now. (id: e8e8ed5)
+```
+
+Once we're ready to start another session (`timeframe`), we just need to run
+`watson start ...` again.
