What took you way too long to figure out?
I was working on an Ecto migration and I needed a timestamp. So, for the nth time, I looked up the different data types for timestamps, and I saw the usec variant (e.g. :utc_datetime_usec), then I searched the docs for the nth time to see if that is the more precise variant.
And then it hit me: The ‘u’ in usec stands for ‘micro’, as in ‘microseconds’. Which is exactly what the ‘usec’ data type is for. I thought it was some random database jargon. I just never made the connection. 
So, Elixir Forum members: What took you way too long to figure out?

On HexDocs, the width of the side panel is adjustable. This can be used to read those really long module names that don’t fit in the sidebar at its normal width.
The draggable handle is pretty small, so I added a screenshot with a poorly-drawn red arrow to highlight it. Works on Chrome and Firefox (and maybe Safari? 
).

quote and unquote. finally clicked thanks to Saša’s incredible Understanding Elixir Macros series. i swear his narration and answers were exactly 30 seconds ahead of me, asking questions

require takes an :as option:
require Explorer.DataFrame, as: DF
I’d been doing alias ..., as: ... + require for forever.

That hard work almost never pays off, not when you are working for other people that is.
…wait, we are talking about Elixir, right?
It took me an embarrassing amount of time to [mostly] understand what does LiveView do but then again I always hated anything UI-related so that likely contributed a lot. Brain resists learning stuff it doesn’t like and all that.

Multiple select, I used two different libraries and tried using CSS and JavaScript before it finally work. Even give up before I saw the live_select library and was able to achieve what I wanted to do with it
https://hexdocs.pm/live_select/LiveSelect.html
Still contemplating on doing a video on my YouTube channel to explain it
