Looks like a great learning article, I like how you built it up over time based on what you wanted done and issues experienced.

Recently I wrote about optimizations that make binary parsing be twice as fast: Binary parsing optimizations in Elixir.

I wrote about a fun, but largely impractical code execution vector for Elixir/Phoenix! Unexpected Code Execution

Sobelow does! And from scanning tons of Phoenix apps I can tell you… it’s a surprisingly common practice 
Mostly in render conn, String.to_atom(x), but occasionally in Map access as well.

I’m still digging into Bitcoin stuff. The Mastering Bitcoin book is an endless sea of inspiration for cool things to build in Elixir.
This week I published another article that digs into using Elixir to generate vanity Bitcoin addresses and makes an exciting detour into parallelizing a CPU-bound algorithm across all cores of your machine using Elixir’s Task.async_stream. Trust me, it’s exciting.

I wrote a blog post demonstrating how to set up a simple dynamic website using Elixir. Apart from the stated purpose, this help in understanding how Plug library inside Phoenix work.

I’d be interested to see how a solution like this that leverages Streams and Task.async_stream would compare to one that leverages Flow and GenStage.
petecorey
Yeah, that would be interesting. I don’t really know much at all about Flow or GenStage. It crossed my mind to use them for this, but I reached for the tools I knew. Maybe I’ll do a comparison in the future.
