      <description>While watching the Maybe Not talk by Rich Hickey it occured to me that I often use the following &amp;ldquo;type narrowing&amp;rdquo; in Typescript.
interface Car {  wheel: string,  brake: string,  gas: string }  function goFast({wheel, gas}: Car) {/* do stuff */} Meaning that I only need certain parts of a car to go fast. With the above definition, I always need to pass the whole car, meaning that</description>

      <description>I constantly keep using the false shortcut for code in Slack and Confluence (Option+Shift+C in Slack, Option+Shift+M in Confluence).
Apparently there is no native key switching in either of these apps to make the shortcut the same.
I ended up using Karabiner-Elements to map my Option+Shift+C to Option+Ship+M, but only if Slack is my foremost window using the following steps.
1. Install Karabiner. Open it to make sure that it works.</description>

      <description>Recently, I had to write a script that finds files that end in .json but not in examples.json, and renames them. Here is a relevant part of the shell script that uses sed.
find . -type f \( -iname &amp;#34;*.json&amp;#34; ! -iname &amp;#34;*.examples.json&amp;#34; \) | while read -r line do  out=$(sed &amp;#39;s/.json/.d.ts/g&amp;#39; &amp;lt;&amp;lt;&amp;lt; &amp;#34;$line&amp;#34;)  echo &amp;#34;$lineconverted to $out&amp;#34; done In another place, I wanted to create a minimal custom CHANGELOG that prints git commits that mention category cool-category in their message (e.</description>

      <title>Setting up ox-hugo</title>

      <description>To set up ox-hugo, I followed the official quick start page.
On MacOS:
brew install hugo brew install go mkdir blog &amp;amp;&amp;amp; cd blog For theme, I could not get hugo mod init to work, so I used the git clone approach. As of the time of writing, I have used the hello-friend-ng theme, which recommends the github submodule installation:
git submodule add https://github.com/rhazdon/hugo-theme-hello-friend-ng.git themes/hello-friend-ng To conclude the theme setup, I have copied the recommended settings to my config.</description>
