+# AWS CLI Requires Groff Executable
+
+I have the AWS CLI installed on this machine, but when I went to run certain
+commands like `aws logs tail my_log_group` or even `aws logs tail help`, I'd
+get the following error:
+
+```
+$ aws logs tail help
+
+Could not find executable named 'groff'
+```
+
+This may only be an issue on MacOS Ventura for older versions of the CLI, per
+[this PR](https://github.com/aws/aws-cli/pull/7413):
+
+> The CLI's help commands are currently broken on macOS Ventura because Ventura has replaced groff with mandoc. This PR fixes the issue by falling back on mandoc if groff doesn't exist in the path.
+
+There are two ways of dealing with this. One would be to install the missing
+dependency, [`groff`](https://www.gnu.org/software/groff/):
+
+```bash
+$ brew install groff
+```
+
+The other is to update the AWS CLI to one that falls back to `mandoc`.
+Depending on how you originally installed the AWS CLI, you can either [follow
+their official install/upgrade
+instructions](https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html),
+`pip install --upgrade awscli`, or upgrade view homebrew (`brew upgrade
+awscli`).

+# Find And Follow Server Logs
+
+Let's say you are authenticated with the AWS CLI and have the appropriate
+CloudWatch permissions. You have a few services running in production with
+associated logs. One of those is a Rails server.
+
+We want to run `aws logs tail`, but first we check how that command works.
+
+```bash
+$ aws logs tail help
+```
+
+We see a bunch of options, but the only required one is `group_name` ("The name
+of the CloudWatch Logs group."). We may also notice the `--follow` flag which
+we'll want to use as well to keep incoming logs flowing.
+
+We need to determine the log group name for the Rails server. We can do that
+from the CLI as well (no need to dig into the web UI).
+
+```bash
+$ aws logs describe-log-groups
+
+{
+    "logGroups": [
+        {
+            "logGroupName": "/aws/codebuild/fc-rails-app-abcefg-123456",
+            "creationTime": 1739476650823,
+            "metricFilterCount": 0,

+        },
+        ...
+    ]
+}
+```
+
+Because the group name is descriptive enough, we can find the log group we are
+interested in: `/aws/codebuild/fc-rails-app-abcefg-123456`.
+
+Now we know what we want to `tail`.
+
+```bash
+$ aws logs tail /aws/codebuild/fc-rails-app-abcefg-123456 --follow

+# SSH Into An ECS Container
+
+In [Connect To Production Rails Console on AWS /
+Flightcontrol](https://www.visualmode.dev/connect-to-production-rails-console-aws-flightcontrol),
+I went into full detail about how to access `rails console` for a production
+Rails app running in an ECS container.
+
+A big part of that process was establishing an SSH connection to the ECS container.
+
+To do that, I need to know my region, container ID, and task ID. I can get the
+first two by listing my clusters and finding the cluster/container that houses
+the Rails app.
+
+```bash
+$ aws ecs list-clusters
+{
+    "clusterArns": [
+        "arn:aws:ecs:us-east-2:123:cluster/rails-app-abc123"
+    ]
+}
+```
+
+The region then is `us-east-2` and the container ID is `rails-app-abc123`.
+
+I can use that to find the task ID:
+
+```bash
+$ aws ecs list-tasks --region us-east-2 --cluster rails-app-abc123
+{
+    "taskArns": [
+        "arn:aws:ecs:us-east-2:123:task/rails-app-abc123/8526b3191d103bb1ff90c65a655ad004"
+    ]
+}
+```
+
+The task ID is the final portion of the URL:
+`8526b3191d103bb1ff90c65a655ad004`.
+
+Putting this all together I can SSH into the ECS container with a bash profile
+like so:
+
+```bash
+$ aws ecs execute-command \
+  --region us-east-2 \
+  --cluster rails-app-abc123 \
+  --container rails-app-abc123 \
+  --task 8526b3191d103bb1ff90c65a655ad004 \

+# Use Specific AWS Profile With CLI
+
+I have multiple AWS profiles authenticated with the AWS CLI. For some projects
+I need to use the `default` one and for others I need to use the other.
+
+First, I can list the available profiles like so:
+
+```bash
+$ aws configure list-profiles
+default
+dev-my-app
+```
+
+For one-off commands I can specify the profile for any AWS CLI command using
+the `--profile` flag.
+
+```bash
+$ aws ecs list-clusters --profile josh-visualmode
+```
+
+However, I don't want to have to specify that flag every time when I'm working
+on a specific project. Instead I can specify the profile with an environment
+variable. The [`direnv`](https://direnv.net/) tool is a great way to do this on
+a per-project / per-directory basis.
+
+I can create or update the `.envrc` file (assuming I have `direnv` installed)
+adding the following line (and re-allowing the changed file):
+
+```
+# .envrc
+export AWS_PROFILE=dev-my-app
+```
+
+Now, any AWS command I issue from that directory or its subdirectories will use
+that profile by default.

+# Filter Blur Requires Expensive Calculation
+
+I had [a
+page](https://www.visualmode.dev/connect-to-production-rails-console-aws-flightcontrol)
+on my blog that was experiencing some odd rendering behavior. The issue was
+manifesting a couple ways.
+
+- Resizing and scrolling were janky and causing entire page layers to re-render
+causing the page to flash in and out.
+- Sometimes entire layer chunks would fail to paint leaving a white block
+missing from the page.
+
+The issue was occurring with and without JavaScript turned on for a
+statically-built page. I suspected that some aspect of the CSS was at fault.
+
+I was going back and forth with Dillon Hafer about what the issue could be and
+he wondered, "could it be the backdrop-blur class from tailwind?". I tried
+removing that class and the responsiveness of the page immediately improved.
+
+The [`filter:
+blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/blur)
+and [`backdrop-filter:
+blur`](https://developer.mozilla.org/en-US/docs/Web/CSS/backdrop-filter) both
+use an expensive [Gaussian blur](https://en.wikipedia.org/wiki/Gaussian_blur)
+calculation. One of these on a modern machine and browser probably won't have a
+noticable impact. However, a bunch of them, as in the case of my page with a
+recurring component, can have quite the performance hit.

+# Prevent Containers From Running On Startup
+
+I have a bunch of docker containers managed by Docker Desktop. Some are related
+to projects I'm actively working on. Whereas many others are inactive projects.
+
+When I restart my machine, regardless of which containers I had running or
+turned off, several of them are booted into a running state on startup. This is
+becaue their restart policy is set to `always`. That's fine for the project I'm
+actively working on, but the others I would like to be _off_ by default.
+
+I need to update each of their restart policies from `always` to `no`.
+
+First, I need to figure out their container IDs:
+
+```bash
+$ docker ps --all
+CONTAINER ID   IMAGE                    COMMAND                  CREATED         STATUS                       PORTS                    NAMES

+```
+
+Referencing the `CONTAINER ID` and `NAMES` columns, I'm able to then inspect
+each container and see the current `RestartPolicy`:
+
+```bash
+$ docker inspect eb9ab2213f2b | grep -A3 RestartPolicy
+"RestartPolicy": {
+    "Name": "always",
+    "MaximumRetryCount": 0
+},
+```
+
+I can then update the `RestartPolicy` to be `no`:
+
+```bash
+$ docker update --restart no eb9ab2213f2b
+```
+
+Inpsecting that container again, I can see the updated policy:
+
+```bash
+$ docker inspect eb9ab2213f2b | grep -A3 RestartPolicy
+"RestartPolicy": {
+    "Name": "no",
+    "MaximumRetryCount": 0
+},
+```
+
+Rinse and repeat for each of the offending containers.

+# Files With Local Changes Cannot Be Removed

+error: the following file has local modifications:

+```
+
+My `.tool-versions` file has some local changes. I don't realize that and I go
+to issue a `git rm` command on that file. Instead of quietly wiping out my
+changes, `git` lets me know I'm doing something destructive (these local
+changes won't be in the diff or the reflog).
+
+I can force the removal if I know what I'm doing with the `-f` flag. Or I can
+take the two step approach of calling `git restore` on that file and then `git
+rm`.
+
+The `--cached` flag is also interesting because it doesn't actually delete the
+file from my file system, but it does stage the file deletion with `git`. That
+means the file now shows up as one of my untracked files.
+
+See `man git-rm` for more details.

+
+I was only thinking about the files local to my project and I forgot that I
+have a system-wide `.tool-versions` file. As we can see from the output, that
+file specifies `postgres` and `lua` as well. Mise wanted to ensure that it had
+downloaded the specified versions of each of those tools before running my

+# Read Existing Dot Env File Into Env Vars
+
+Just about any web app that I've worked on has had a `.env` file as a way of
+configuring aspects of the app specific to that environment. These typically
+are read into the environment with a language-specific
+[dotenv](https://github.com/bkeepers/dotenv) tool.
+
+Mise supports this convention. In addition to specifying individual non-secret
+env vars, you can also instruct `mise` to read-in a `.env` file like so:
+
+```toml
+[env]
+PORT=3344
+_.file = ".env"
+```
+
+The `_.file` line tells `mise` that there is a file `.env` with key-value pairs
+that it should read in. It can even handle `.env.json` and `.env.toml` file
+formats.
+
+To ensure that `mise` is picking up the values from the `.env` file, you can
+run the following command and make sure they show up in the output:
+
+```bash
+$ mise env
+```

+# Adjust The Production Log Level
+
+A Rails app by default takes on the `debug` log level. This is great for
+development because it spits out a lot of information as you build and debug.
+
+That's going to typically be a bit too noisy for a production environment
+though. That is why Rails ships with the `config/environments/production.rb`
+file configured to the `info` log level.
+
+```ruby
+# config/environments/production.rb
+Rails.application.configure do
+
+  # ...
+
+  # "info" includes generic and useful information about system operation, but avoids logging too much
+  # information to avoid inadvertent exposure of personally identifiable information (PII). If you
+  # want to log everything, set the level to "debug".
+  config.log_level = ENV.fetch("RAILS_LOG_LEVEL", "info")
+
+  # ...
+end
+```
+
+Sometimes, like when we're trying to track down some buggy behavior, we may
+want to switch Rails from one log level to another. That's why it is configured
+by the `RAILS_LOG_LEVEL` env var and otherwise falls back to `info`.
+
+To, for example, switch production over to the `debug` log level, we'd first
+change the `RAILS_LOG_LEVEL` env var to `debug`. Then we'd need to make sure
+our Rails app is restarted so that the config change is picked up. Heroku's
+`heroku config:set` will do that automatically. Depending on your setup, you
+may need to manually restart your web server (e.g. Puma).

+# Enforce Locals Passed To A Partial
+
+I have a big form partial (`_form.html.erb`) that is rendered by several
+different _new_ and _edit_ views. It's hard to tell at a glance, but the
+partial requires that `blogmark` and `cancel_path` are included as locals when
+it is rendered.
+
+As of [Rails 7.1](https://github.com/rails/rails/pull/45602), we now have a
+built-in way to enforce locals passed to a partial. We can add a magic comment
+at the top of the partial that specifies the locals:
+
+```ruby
+<%# locals: (blogmark:, cancel_path:) -%>
+<%= form_with(model: blogmark, local: true, class: "w-full max-w-3xl mb-8") do |form| %>
+  <% ... %>
+<% end  %>
+```
+
+This particular ERB magic comment declares that
+[`blogmark`](https://still.visualmode.dev/blogmarks) and `cancel_path` are
+required locals.
+
+So, what happens if I have a `new.html.erb` view that looks like this:
+
+```ruby
+<h1>New Blogmark</h1>
+
+<%= render 'blogmarks/form', blogmark: @blogmark %>
+```
+

+Updating the `render` statement to include a `cancel_path` local fixes the
+issue.

+# Find All Tool Version Files Containing Postgres

+Many of them specify Ruby and Node versions. Some of them also include

+
+By combining [`fd`](https://github.com/sharkdp/fd) (a better `find`) and

+# Fix Previous Command With fc

+The `fc` command is a Bash and ZSH built-in command that allows you to interact
+with the history of commands issued in the shell. The most straightforward use
+case I know of for using this command is to fix or edit some aspect of the
+previous run command.
+
+When `fc` is executed with no arguments or flags, it will grab the latest entry
+to the command history and load it into your default editor. For me, that is
+Vim.
+
+I can make edits in that Vim session like I'd do in any other Vim session. When
+I write and quit (`:wq`) the file, the updated command will be executed. This
+is useful if, say, I've made a typo in the previous command and would prefer
+the ergonomics of my default editor to fix it. Or let's say I have a really
+long command with many flags and long file path arguments. It would be much
+easier and quicker to edit those paths from my editor than from the terminal
+prompt.
+
+If I've opened my editor (Vim) with `fc` and I decide I don't want to execute
+the command after all, I can _compiler quit_ Vim (exit with an error code)
+using `:cq`. The command will not be executed in this case.

+- The `ps` command lists processes that "have controlling terminals"
+- The `$$` is a special shell variable representing the PID of the current process (try `echo $$`)
+- The `-p` flag allows you to specify a PID for `ps` to grab, in this case, the `$$` PID
+- The `-o` flag allows us to specify the output format, such as the PID and command name
+- The `=` after `pid` and `comm` tell `ps` to exclude headers from the output
+
+Additionally, I noticed that it output `-zsh` (not just `zsh`). That leading
+hyphen seems to indicate that [this `zsh` process is a _login
+shell_](https://unix.stackexchange.com/a/46856/5916). That means it was the

+
+First, you can access the todo syntax with a forward slash command. Type `/`
+and then start typing `TODO`. It will show up as a top result. Hit enter and
+you'll have a fresh todo item that you can add a description to.
+
+Second, as the above hints at, we can get right to the todo syntax by typing
+one of `TODO`, `NOW`, or `LATER` in all caps followed by a description. For
+example:
+
+```
+TODO Send out invoices
+NOW Reply to those emails
+LATER Schedule that meeting
+```
+
+These will render as checkable boxes marked as either `TODO`, `NOW`, or
+`LATER`, until they are checked off.

+You can also search for blocks that match one of these three categories.

+`~/.zshrc` file and need verify them as I go.
+
+```bash
+alias reload='source ~/.zshrc'

+
+With this alias, I can call `reload` from the terminal and the latest version
+of my configuration (according to the `~/.zshrc` file) will be loaded for that
+shell instance.
+
+This has some downsides. It doesn't account for the other kinds of files that
+contribute to your shell configuration (e.g. `~/.zprofile`) and it can lead to
+duplicate values in your `PATH` and init scripts being run an additional time.
+
+A better way is to use:
+
+```bash
+$ omz reload
+```
+
+This is [a wrapper call around `exec
+zsh`](https://github.com/ohmyzsh/ohmyzsh/blob/master/lib/cli.zsh#L669-L677),

+
+First `take` creates and `cd`s into `take-demo`. Then `take` only `cd`s into
+`already-exists`. Then we see that `take` can create multiple levels of nested
+directories.
+
+With the help of `which` we can see how `take` is defined:
+
+```bash
+$ which take
+take () {
