I am in the process of putting together a in depth 2 part blog series on setting up Prometheus and Grafana along side a PostGIS powered Phoenix application. I published Part 1 yesterday: Prometheus, PostGIS and Phoenix Part 1-Alex Koutmos | Engineering Blog
Stay tuned for part 2!
Hey! I wrote a post on my first experience with Property based tests in Elixir… It was my first medium post so feedback is very appreciated, hope u like it!

This article comprises of common Elixir coding techniques that you may or may not know.
We usually encounter a situation like we expect a map has certain key and if not we need to send some default value.
Immediately, we will end up using Map.has_key? like in the following way
currency =
if(Map.has_key? price, "currency") do
price["currency"]
else
"USD"
If you see any such lines in your code then it is time to refactor them as
currency = Map.get(price, "currency", "USD")
However, you can also take this to the next level like
currency = price["currency"] || "USD"
Except these will not work in the same way when price = %{"currency" => nil}, and this is an important difference.
Enum.map(pickup, fn
{"latitude", lat} -> {"lat", lat}
{"longitude", long} -> {"long", long}
{"pickupId", pickup_id} -> {"pickup_id", pickup_id}
{"stopName", stop_name} -> {"stop_name", stop_name}
{"zip", zip} -> {"zipcode", zip}
anything -> anything
end)
|> Enum.into(%{})
Every time someone does Enum.map(map, function) |> Enum.into(%{}) Map.new/2 cries. 
Of course you are right. I just considered no-key and key with value as nil are both same. I will update like you said.
Anyway, Good Catch 
Yeah. I have to cry now 
.
I was using before as I don’t have an idea of using Map.new/2. If I have to work on any Enumerable data, Immediately mind goes for Enum module.
Thanks for reading and update. I’ll update it in the article.
