Install mutiple Erlang and Elixir with vfox
Theoretically, you could install any version that appears in https://github.com/erlang/otp/releases. Since it is compiled and installed from source, the installation process will take some time. When you see the following message, the installation is complete.

Perfect Elixir: Environment Setup
I’m on MacOS and erlang.org, elixir-lang.org, and postgresql.org all suggest installation via Homebrew, which is a very popular package manager for MacOS.

Why are there so many languages?
Funny that you should mention Erlang. Looking at the Github for Erlang, it appears that the source for Erlang is 16.8% written in C. I would bet these are not the least important bits of the whole thing. So, Erlang depends on C.

Erlang: More Optimizations in the Compiler and JIT
It looks more like some of the JIT improvements made it profitable to manually unroll some loops in the base64 module: https://github.com/erlang/otp/commit/a03cf1601605dee767cd9d5...

Mixing sync and async views in the same application
https://github.com/erlang/otp as far as I know. It's somewhat confusing and I honestly couldn't say exactly where the BEAM VM or OTP or ERTS (Erlang Runtime System) start and end. I've never dug into it. I just install Elixir and sometimes Erlang through the ASDF tool, which does all the compiling for me.
- When people send a https request to my custom web server, it crashes the entire system. How do I fortify my system not to accept em?

Reaching 100M MQTT Connections with EMQX 5.0
For deploying and running our cluster tests, we used AWS CDK, which allowed us to experiment with different instance types and numbers, and also trying out different development branches of EMQX. You can checkout our scripts in this Github repo. In our load generator nodes ("loadgens" for short), we used our emqtt-bench tool to generate the connection / publishing / subscribing traffic with various options. EMQX's Dashboard and Prometheus were used for monitoring the progress of the test and the instances' health.
