ElixirConf 2015 - OTP Has Done It by Nick DeMonner

As a young community, we have to resist the urge to reinvent the wheel for foundational libraries and instead look to the battle-tested awesomeness that is OTP. When designing complex systems with many moving parts in Elixir, we should ask ourselves the following question: has OTP done this? In order to answer that question in this talk, we'll first look at the gen_fsm, gen_event, and gen_server libraries. We'll see some examples illustrating how, where, and why they should be used for building robust, fault-tolerant, and distributed systems. A broad discussion of some of the built-in database options like ETS and Mnesia will follow. We'll examine the pros and cons of each system, and take a look at some examples. Lastly, attendees will get a brief overview of OTP-style releases and how they can fit into modern deployment infrastructure.

I liked how Nick took a moment to say "this is the one we use almost all the time" in several spots (one-for-one restart strategy, gen_server): in most docs, they feel obliged to give equal treatments to all options, which makes it feel like they're equal in importance/utility. Saying "stick with this until it doesn't fit" is a great focusing tool when learning a new system, allowing me to defer learning the also-rans until later.

completely agree, "What to choose" is pretty hard question for every newcomer

[@yelgabs]

Would've loved to hear the questions as well.
Going through these conf videos is frustrating when the questions at the end are being cut off.

This was incredibly helpful, both in general and in my specific goal of writing an OTP doc page for Elixir's API reference docs. Thanks!

[@LarsBahner]

Thank you. Finally an alchymist the speaks human. Just Thank our💚

A slightly cleaner link for the Erlang doc referenced at 3:30 is erlang.org/doc/design_principles/des_princ.html
Exciting stuff!

Thank you for this link Bill.
