If you haven't noticed, I have a new [coding]({{< ref "/categories/coding" >}})
section on this site.

For the sake of not "polluting" the main RSS feed, coding posts do not make it
to `/index.xml`. Instead, they have their own
[coding](/categories/coding/index.xml) feed.

I have also moved my [advent of code](https://adventofcode.com/) posts there.

Problem sets:

* [**LeetCode**](https://leetcode.com/)
  * [LeetCode Explore](https://leetcode.com/explore/)
  * [LeetCode Card Track](https://leetcode.com/explore/featured/card/the-leetcode-beginners-guide/679/sql-syntax/4358/)
