[erlang-questions] The future of Erlang and BEAM

[Max Bourinov]

Hi Radek,

Before answering your question, could you please clarify to the list what
is so special in "LMAX Disruptor"? Why it is impossible to implement it in
Erlang? Does it really makes sense to use this technology? I asked those
questions because I read about "LMAX Disruptor" while ago, but I didn't
find anything special in it. Moreover for me is seems as an obvious thing
in a shiny package.

About Java vs Erlang: After many years in Java world (banking, investing,
transportation) I started to work with Erlang (including all guys in our
company). Now all our software is written in Erlang/C. It handles
huge payload, very easy to scale, in case of problems it heals itself
automatically. It is very easy to develop and maintain software in Erlang.
This is a true dream technology. We are really happy now. I don't see any
Java use cases in our company in the future.

p.s. Of course Erlang is not designed for UI.

So, thanks again for Ericson company and all those great people that
developed Erlang (I hope you read this mail. I am really proud to know you)
and all of those people that contribute to Erlang/OTP. Thank you!

Best regards,
Max
