Protohackers in Elixir: day 1 - Prime Time

Andrea Leopardi solves the Protohackers Prime Time challenge by building a TCP server in Elixir that validates prime numbers.

This is the second video of my "Protohackers" Elixir series. We're solving network challenges from protohackers.com. I’m deploying code using a free account on fly.io. The source code is on GitHub: github.com/whatyouhide/protohackers_in_elixir Some resources for the video: • "inet:setopts/2" documentation (for the "packet" option): erlang.org/doc/man/inet.html#setopts-2 • Deploying Elixir applications on Fly.io: fly.io/docs/elixir/getting-started/legacy • Documentation for the Erlang gen_tcp module: erlang.org/doc/man/gen_tcp.html Other resources: • My website: andrealeopardi.com • Twitter: twitter.com/whatyouhide • Mastodon: mas.to/@whatyouhide • #Elixir's website: elixir-lang.org Music from Uppbeat (free for Creators!): [uppbeat.io/t/walz/name](uppbeat.io/t/walz/name) License code: WX2ISVMMX8I1FJMDThis is the first video of a series on solving some network programming challenges in Elixir ([elixir-lang.org](elixir-lang.org/)).
