+# Useful ActiveSupport Constants For Durations
+
+Whenever I'm passing a duration to a function, I like to [name it with the
+unit](https://ruudvanasseldonk.com/2022/03/20/please-put-units-in-names)
+relative to the value it represents. For instance, if I need to pass in an hour
+duration in seconds, I might write the following line:
+
+```ruby
+hour_in_seconds = 60 * 60
+
+# or
+
+hour_in_seconds = 3600
+```
+
+ActiveSupport has a [Duration
+class](https://api.rubyonrails.org/classes/ActiveSupport/Duration.html) with a
+series of constants that we can reach for.
+
+```ruby
+> ActiveSupport::Duration::SECONDS_PER_MINUTE
+=> 60
+> ActiveSupport::Duration::SECONDS_PER_HOUR
+=> 3600
+> ActiveSupport::Duration::SECONDS_PER_DAY
+=> 86400
+> ActiveSupport::Duration::SECONDS_PER_WEEK
+=> 604800
+> ActiveSupport::Duration::SECONDS_PER_MONTH
+=> 2629746
+> ActiveSupport::Duration::SECONDS_PER_YEAR
+=> 31556952
+```
+
+Though it is fun to know about these, we should keep in mind that this class
+provides support for what is likely to be a more useful abstraction layer:
+
+```ruby
+> 1.hour
+=> 1 hour
+> 3.hours
+=> 3 hours
+> 1.day.to_i
+=> 86400
+```

+# Allow Key-Repeating With Cursor
+
+I recently installed the Vim extension for Cursor. This is the same extension
+for VSCode since Cursor is built on VSCode. A lot of the expected Vim behavior
+was working. However there was one glaring point of friction.
+
+I often hold down keys like `k` and `j` to go up and down several lines when
+I'm absent-mindedly scrolling around. This wasn't working with the Vim mode
+extension. I'd hold `j` down and the cursor would move down a single line and then
+stop.
+
+The first thing the Vim extension tells you to do is run a command to enable
+key-repeating. These instructions are specific to VSCode:
+
+```bash
+$ defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false
+```
+
+That won't work for cursor which is a separate application with a distinct
+`CFBundleIdentifier`. You can check the current identifier in Cursor's
+`Info.plist` file to be sure, but it should be `com.todesktop.230313mzl4w4u92`.
+
+Run this to target Cursor:
+
+```bash
+$ defaults write com.todesktop.230313mzl4w4u92 ApplePressAndHoldEnabled -bool false
+```
+
+Then restart Cursor.
+
+Now key-repeating in Vim mode should be working.
