Community Feedback
"A must-read for any #erlang or #elixirlang developer."
"Recent discussion reminded me about this great book on lower‑level working of ERTS/BEAM by @erik_stenman. Highly recommended; I'll reread it myself :-)"
"I kept going because I wanted to understand the BEAM properly. There's value in following the real logic, not just the surface explanations."
"The BEAM really feels like alien tech left from a highly advanced civilization and this book dropped in at such a great timing! Bought it right away, kudos to Dr. Erik Stenman for keeping it up after two cancellations!"
"Bought it instantly, even if it's available online for free—I guess this way supports the author a little bit."
"Plenty of documentation can be found about the JVM, but BEAM has always seemed like a bit of a mystery to me. This is great!"
"Books ask for a lot of organization in general. And books on an evolving subject never stop asking. I don't use Erlang, but for 13 years in the making, I'm getting a copy. Thank you."
"Thank you for writing this book! I really wanted this a few years ago as I was debugging production Elixir, when existing learning sources were pretty dense and dry (or too simple and shallow)."
"I found the philosophical part useful for the team to design our applications."
"Continue being awesome."
