There is no need to use case inside of anonymous function - instead, we can create function with multiple heads. list = [1, 2, 3, {4, 5}, 6, {7, 8}] Enum.each(list, fn {first_value, secon_value} -> IO.puts("Tuple: #{first_value}, #{secon_value}") element -> IO.puts("Simple element: #{element}") end) ...
I’ve just learned that if you want to use a dollar sign inside Makefile you need to escape $ with an extra $. For example: LATEST_COMMIT := $(shell git log --oneline | head -1 | awk '{print $1}') It won’t work because make thinks that we are accessing make variable. If we want to use this awk command inside Makefile we need to escape the $ LATEST_COMMIT := $(shell git log --oneline | head -1 | awk '{print $$1}') ...

Imagine you have a process which is responsible for consuming some sort of queue and spawning a separate process for each given job. Each of the job processors later called workers communicates with some infrastructure layers for eg. external API, database, etc. We are injecting infrastructure to workers via configuration: defp current_impl do Application.get_env(:scanner, :ensure_file, __MODULE__.AwsImpl) end Each injected implementation must implement complementary behaviour for eg. defmodule Scanner.Scans.EnsureFile.Impl do @callback call(String....

When you forgot to use secrets from the very beginning - and some secrets landed in your repository eg. login/password/secret_key you can remove them in a simple way using filter-branch for example to remove password you need to use: git filter-branch --tree-filter "find . -type f -exec sed -i -e 's/password/**REMOVED**/g' {} \;" It will replace password with **REMOVED** in the whole repo and commits....
