Coding theory was a required class in my computer engineering program, I don't think it's super esoteric. This looks like a pretty nice, thorough document.

This looks very pretty. I guess there’s no option to self-host or run locally? My company wouldn’t allow internal diagrams on a 3rd party cloud service, unfortunately. Especially infra / networking, given the security implications...

It’s not exactly what the quote says - 90% of the traffic goes through nodes _controlled by Erlang_. See: https://news.ycombinator.com/item?id=17218190

Two years ago a new SSA representation was added. There’s a series of posts on the official blog that explain it well: http://blog.erlang.org/introducing-ssa/

Erlang/OTP-22 (released last year) introduced TLS distribution optimizations and message fragmentation which sound very related to the problem you saw: http://blog.erlang.org/OTP-22-Highlights/ The fragmentation i

> we technically cannot use the word engineer in our title Just for completeness: it’s OK to use the title “B. Eng.”, which means you have a Bachelor’s in engineering, without implying anything about being a professional engineer.

In my experience with Python, these were minor annoyances. The real problem was the amount of decorators and monkey patching in libraries like Flask, FoundationDB, Gunicorn, or Celery. Using gevent didn’t help...

A behaviour defines an interface a module can implement, nothing more. A good example of a behaviour that doesn’t involve any process is the SSL session cache: http://erlang.org/doc/man/ssl_session_cache_api.html

There is an attempt at it, yes: https://wiki.haskell.org/Cloud_Haskell Many languages have some variation of Erlang’s processes and/or distribution available as a library, but the key features like live inspection, cod

Was that a long time ago? The tooling has improved massively after Elixir and Hex appeared. The upcoming “Adopting Erlang” book goes into that history a bit: https://adoptingerlang.org/docs/development/dependencies

I don’t think it’s a common abbreviation for Windows developers. Process Explorer calls that “working set” instead.

The website turns into a Phoenix error page telling you to restart the app because config has changed.

It’s rare in production, but fantastic in development. Often I don’t even restart my Elixir app when switching between git branches, because the hot reload is enough.

Nowadays in Erlang you can set a memory limit per process[1], ensuring they get killed if they try to allocate more. Of course you still have to estimate how much is reasonable which isn’t always obvious... [1] See max_heap_size under http

> the messages sent are kept in shared memory (which is reference-counted) Only large binaries and slices of them use reference counting, other things are copied. And of course, if the process is remote, everything is copied :)
