 ### 1. Nerves supports lean systems and operates well in low-bandwidth areas
 
-Because Nerves bundles entire applications into relatively small archives in terms of firmware images for full Linux systems, Farmbot can use NervesHub to send over-the-air updates more quickly and users can download them faster. For comparison, an Android update generally clocks in at around 4 GB, but a Nerves update can be packed into as little as 12 MB.

 ### 2. Nerves adds convenience with low overhead
 
-For devices that are already connected to the internet, connecting to Nerves requires no additional configuration because NervesHub is compatible with the current public key infrastructure for device-to-cloud communication. Since Farmbot already had internet-connected devices when they brought Nerves onboard, they were able to use the same "key" to sign in to NervesHub that they use for their cloud service.

Since Farmbot already had internet-connected devices when they brought Nerves onboard, they were able to use the same "key" to sign in to NervesHub that they use for their cloud service.
 
 ### 3. Nerves has all the benefits of Elixir and Erlang
 
 Because it's written in Elixir and built within the Erlang runtime system, Nerves retains the qualities of that language and framework — notably that they are distributed, fault-tolerant, soft real-time, and highly available. Connor also says that with Nerves, it's easy to reason about the things you build with Nerves because you only input what you need into a Nerves application, helping you to avoid unnecessary complexities or unforeseen security vulnerabilities. You can check up on devices as they're running and debug them without disruption to the user experience.
 
 ## The result
 
-FarmBot now has around 300 devices live in NervesHub, with a different deployment for each of their device models. Nerves is built to scale, so as Farmbot continues to grow its user base and expand their product capabilities, they'll be able to continue developing and releasing reliable firmware updates using Nerves.

 According to Matthew Peck, "the paradigm shift from Object-Oriented languages to Functional Programming was our biggest challenge when first learning Elixir". However, the team agrees the investment was worth it: "Learning Elixir has made us better programmers. We have found that immutability made our code more readable, easier to test, and simpler to make concurrent. Now when we go back to an Object-Oriented language, we are thinking about how we can apply the same concepts there" - said Mike Hagerdon.
 
-Amanda Dolan added some remarks on Elixir's capabilities for writing concurrent and fault-tolerant applications: "One other challenge when learning Elixir is fully grasping concurrency and the Erlang/OTP patterns". Some of them felt it took longer to master those concepts than they first expected.

 Taylor Mock has his take on the challenges teams may face when adopting Elixir: "Another difference between Elixir and our previous stacks, Ruby and Node.js, is in the ecosystems". They were initially concerned that the Elixir ecosystem would lack when it comes to third-party tools, but that was not what they saw. Taylor continues: "We found out that we can get really far with the concepts and mechanisms that the language itself provides. This shift can be scary, but we are now past it, and we find ourselves with leaner applications and fewer dependencies".

 ## Communication at scale
 
-Effective communication plays an essential role when handling millions of connected users concurrently. To put things into perspective, some of Discord's most popular servers, such as those dedicated to Fortnite and Minecraft, are nearing six hundred thousand users. At a given moment, it is not unlikely to encounter more than two hundred thousand active users in those servers. If someone changes their username, Discord has to broadcast this change to all connected users.

 Overall, Discord's communication runs at impressive numbers. They have crossed more than 12 million concurrent users across all servers, with more than 26 million WebSocket events to clients per second, and Elixir is powering all of this.

 ## Growing with the platform
 
-Shortly after, Slab was in a private beta with a handful of companies as users. For each major feature they had along the way, Elixir and Phoenix provided the building blocks for it. When they implemented real-time comments, they used Phoenix Channels and Phoenix PubSub. The pattern goes on: "for asynchronous processing, we simply use [Elixir tasks](https://hexdocs.pm/elixir/Task.html)". Later on, to track users editing a document and give each a different cursor color, they used [Phoenix Presence](https://hexdocs.pm/phoenix/Phoenix.Presence.html), a tool that no other web framework offers out-of-the-box.

 Another leap in Jason's journey with Slab and Elixir was when he had to learn Erlang/OTP, a group of behaviors that ship as part of Erlang's standard library for building distributed and fault-tolerant applications.

 Community members are welcome to propose new features for Elixir. Before submitting a proposal, members are encouraged to gather feedback from around the community in whatever venues seem best. However, in order for a proposal to be considered for inclusion by the Elixir Core team, it must go through the Elixir mailing list. This often includes discussion and refinement of the proposal. The Elixir Core team has the final say on whether a proposal is accepted or rejected. While members are encouraged to gain support from the rest of the community, popularity does not mean that a proposal will be accepted.
