Functional Programming meetup

With OSCON in town this week, bringing to town many from the functional programming community among others, we thought it would be a good idea to hold a casual functional programming meetup. There's no agenda and no talks, but there will be beer and good conversation.

We'll be meeting up on the patio at Green Dragon. If you're just visiting and are worried you won't recognize the geeks when you get there (we're usually easy enough to spot), feel free to ping people on the PDXFunc mailing list (https://groups.google.com/forum/#!forum/pdxfunc) or on IRC at #pdxfunc.

Erlang and Elixir Meetup
CrowdCompass office in the Ford Building

The next PDX Erlang and Elixir Meetup is this Wednesday from 6:30pm to 8:30pm at CrowdCompass.  Mexican food from Los Gorditos will be provided. Vegan and gluten free options available.  Email [email protected] if there is something specific you'd like to try from their menu (links at bottom).

There's still room on the agenda if you have something to discuss, otherwise we'll open it up for general discussion.  The agenda so far:

Stephen Peters will give a recap of his time at Erlang Factory in San Francisco earlier this month and possibly demo a new monitoring tool for the Erlang VM.

Daniel Hedlund will be giving a brief overview of erlank.mk, rebar and relx and how they fit into the Erlang app development ecosystem.  He will also present a bare bones cowboy app and go over each of its components, and how to pull in other dependencies like redis and json libraries.  The app will be made available on GitHub so you can clone and experiment after the meeting.

Hope to see everyone there!

Introduction to Elixir from a Ruby, Python and Javascript perspective
CrowdCompass office in the Ford Building

We are the Portland Erlang and Elixir meetup.

Matthew Lyon will give an “Intro to Elixir” presentation from and for the perspective of people coming from scripting languages such as Ruby, Python, and Javascript.

Elixir is a functional, meta-programming aware language built on top of the Erlang VM. It is a dynamic language with flexible syntax and macro support that leverages Erlang's abilities to build concurrent, distributed and fault-tolerant applications with hot code upgrades.

José Valim is the creator of the Elixir programming language. His goals were to enable higher extensibility and productivity in the Erlang VM while keeping compatibility with Erlang's tools and ecosystem.

We've also secured a free month subscription to Elixir Sips (http://elixirsips.com/) for everyone. Elixir Sips releases two videos every week to help you get started learning Elixir and keeping up with new tools and libraries. Feel free to pass the link along to anyone you know who might be interested.

Offer expires May 16th: https://elixirsips.dpdcart.com/subscriber/add?plan_id=176&plan_term_id=376

Mexican food from Los Gorditos will be provided. Vegan and gluten free options available. Email [email protected] if there is something specific you'd like to try from their menu: http://www.losgorditospdx.com

We look forward to seeing you!

Learning Erlang made me a better engineer and architect
SnapFlow

Nathan Aschbacher throws down on his favorite Erlang topic:

Learning Erlang made me a better engineer and architect.

Even if you don't think you have a use-case for Erlang, don't have an interest in functional programming, and find reading Prolog inspired syntax directly proportional to your increased consumption of Excedrin... according to Nathan Aschbacher (currently Chief Architect at Snapflow and previously Principal Consulting Architect at Basho) you should learn Erlang anyway.

Nathan will be presenting on his path to Erlang and functional programming, his initial disdain, his later begrudging respect, and finally his eventual love and nostalgia for all things Erlang-y.

Join us and share in the conversation.

"Let's get functional... functional." -Olambdia Newton-John

We'll be kicking off the first in a series of Elixir Games meetups. The "Games" format is designed to create a bit of friendly competition and is accessible for all ranges of experience; beginners and pros alike.

Early in this series we'll be focusing mostly on solving problems in a functional paradigm, and as the series continues over time we'll move more and more toward Elixir's differentiators; Erlang interop, hygienic macros, OTP patterns.

If all that read like gibberish to you, don't worry you don't have to know any of that jargon, and by the time you do everything will already make sense. Because we'll introduce ideas and concepts in a way that will help you understand those things conceptually before you ever need a weird name for them.

Food and drink will be provided. There will also be small desk fodder prizes for the winning teams.

Please make sure you come with a computer to work on and have Elixir pre-installed locally or in a VM and ready to go.

Portland Erlang / Elixir Meetup
Lucky Labrador Brew Pub

Daniel Hedland of CrowdCompass will be leading April's meeting.

Learn more about how Unix shells compose simple programs to solve complex tasks and how these processes interact with each other under the hood. We will discuss how Unix processes behave compared with standard Erlang and Elixir processes and how the Erlang VM could be used to emulate common patterns found in the Unix shell.

A very basic REPL will be provided to play around with some of these ideas. After the discussion, we will break out into groups to try to re-implement some common Unix commands in your favorite ErlangVM-based language and then use shell composition to solve a set of everyday problems.

Elixir Games PDX - "JVMergy independence is a matter of national security"
Puppet

Can you build a data processing pipeline that might one day help save humanity? For this next meetup we'll be looking at one of Elixir's features that sets it distinctly apart from its older Erlang sibling.... the Pipeline Operator.

In the previous two Elixir Games PDX meetups we've looked at how to solve some simple problems in a functional programming style, and we've also taken a look at Elixir's concurrency and parallelism paradigm. We'll be partially combining some of those principles and practices to mine some critical data.

Until now we haven't focused much at all on a huge part of what makes Elixir great... seamless access to Erlang OTP. OTP, or Open Telecom Platform, is a set of frameworks and tools that make it relatively easy to build robust, fault-tolerant, and scalable applications. In this Elixir Games we're going to focus specifically on the Supervisor. Well-defined supervision strategies are the bedrock of all exceptional Elixir software (Erlang and LFE too).

10 Billion a Day, 100 Milliseconds Per: Monitoring Real Time Bidding at AdRoll - Portland Erlang / Elixir Meetup
eBay Community Lounge

10 Billion a Day, 100 Milliseconds Per: Monitoring Real Time Bidding at AdRoll

Brian Troutwine of Adroll will be joining us tonight. Adroll uses Erlang to power their high-speed, never-stop online advertising services. That's right, 10 billion transactions a day.

Brian's talk will provide motivation for the extensive instrumentation of complex computer systems and make the argument that such systems are essential. This talk will provide practical starting points in Erlang projects and maintain a perspective on the human organization around the computer system. Brian will focus on getting started with instrumentation in a systematic way and follow up with the challenge of interpreting and acting on metrics emitted from a production system in a way which does not overwhelm operators’ ability to effectively control or prioritize faults in the system. He’ll use historical examples and case studies from my work to keep the talk anchored in the practical.

Talk objectives:

Brian hopes to convince the audience of two things:

• monitoring and instrumentation is an essential component of any long-lived system and

• it's not so hard to get started, after all.

He’ll keep a clear-eyed view of what works and is difficult in practice so that the audience can make a reasoned decision after the talk.

Last time we looked at Supervisor hierarchies, and unintentionally on my part almost everyone picked up the GenServer behavior as a component of their solution. Damnable misleading documentation! However that prompted a further conversation about GenServers and other components of OTP (the Open Telecom Platform). In the spirit of learning and disambiguating things we'll take a deeper look at some of these architectural patterns in Elixir and how they can help us better organize our projects and design better systems.

Erlang/OTP at the Jedi Temple
Househappy

If you've heard of Erlang, perhaps you've also seen the acronym "OTP". What the heck is "OTP" and why do the Jedi refer to it as the "magic" that gives Erlang it's reputation for scalability and fault tolerance?

Why is it called Erlang/OTP? What gives? How does this relate to Elixir? What should I know about it?

Nathan Aschbacher of Visa and Elixir Games PDX has kindly agreed to join us and share his wisdom, give us an overview and also, to levitate R2D2.

We parted ways from the normal format of this meetup last time, and instead of working on the problem stated, we ended up working on trying to get a relatively complex Erlang project (erl-dns) to build using only Elixir's build chain as well as added an Elixir module to the project to ensure that we could attempt to extend the project using only Elixir code.

Designed to handle anything from large carrier to small countries, the Kazoo infrastructure can do it all. There are no lock-ins and the software is open-source to give you complete freedom.

James will be giving us a high level view of the architecture behind Kazoo, both from a platform perspective and from an Erlang perspective. We'll survey some of the code that is of interest, such as the gen_listener behaviour (for AMQP message consumption), the PropEr tests in various modules, the wh_json module for working with Erlang-encoded JSON objects), and more. No telecom experience required!

Elixir Games PDX - As With All Things, It's All About the Atoms
Puppet

This month we'll be continuing down the path of analyzing and modifying a production-grade open source project. Last month many people who attended were able to discover where in erl-dns our custom zone-file handling code should go. This month we'll drive toward a real replacement implementation to take the next step toward being able to make incremental zone updates and pave the way toward DNS-SD functionality.

This month we'll continue the games format, but instead of a contrived problem we'll continue down this path of modifying and contributing to an open source project.

For the newcomers, the "Games" format is designed to create a bit of friendly competition and is accessible for all ranges of experience; beginners and pros alike.

If you'd like to take a look at the previous sessions' exercises feel free to check them out here: https://github.com/elixir-pdx/, some submitted solutions are available on non-master branches.

Early in this series we'll be focusing mostly on solving problems in a functional paradigm, and as the series continues over time we'll move more and more toward Elixir's differentiators; Erlang interop, hygienic macros, & OTP patterns.

If all that read like gibberish to you, don't worry you don't have to know any of that jargon, and by the time you do everything will already make sense. Because we'll introduce ideas and concepts in a way that will help you understand those things conceptually before you ever need a weird name for them.

Food and drinks will be provided. There will also be small desk fodder prizes for the winning team.

Please make sure you come with a computer to work on and have Elixir pre-installed locally or in a VM and ready to go.

Elixir Games PDX - Many Types of Success, But Only One Success Type
Puppet

NOTE: Please RSVP via the meetup.com website, it helps for food and beverage planning.

Last month we had a really varied mix of experience levels in attendance, and so this month we'll cover a subject that will be useful to audiences and participants of all shapes and sizes... Dialyzer & TypeSpecs. Elixir isn't a statically typed language, but thanks to TypeSpecs and Dialyzer we can do static type analysis and avoid whole horrible classes of runtime errors by checking our code at compile-time.

Elixir Games PDX - Every step you take, every proc you break... we'll be watching you.
Puppet

Elixir inherits a tremendous suite of debugging, tracing, and monitoring facilities from its Erlang pedigree, where the use case was something shaped like, "Be able to attach to, live trace, muck with, and live zero-down-time upgrade this service running on a thing dangling from a 10m pole in the backwoods of Siberia." In this month's meetup we'll take a look at some of these tools and use them to poke around some running services.

The Elixir language and standard library is always in a state of diligent improvement, and in accordance with that trend GenStage was recently added. GenStage is a core generic behavior designed to provide a way of coordinating communication between processes with built-in back-pressure.

Elixir Games PDX - Architecture: It's Not Just for Skyscrapers
Puppet

This month we're going to take a look at the architecture of a couple open source Elixir libraries, talk about them, how they fit with OTP principles that Elixir inherits from the Erlang ecosystem, and devise a strategy for how to bring the existing design into line with a more OTP-y way of doing things. We'll also discuss why that's valuable or desirable and start to iterate on making those changes together.

Elixir Games PDX - Interproconal Communication Skills
Puppet

Elixir and Erlang make tremendous tools for integrating between different kinds of interfaces. In fact there's arguably no better system for quickly constructing reliable and fault-tolerant control planes available today. However, in order to do that in a rich ecosystem of technologies it is a requirement that we be able to interact with and orchestrate various kinds of external processes. So for this meetup session we're going to learn about exactly how to do that.

Elixir Games PDX - Learning to Love Property Tax
Puppet

Many developers are probably familiar with unit-testing, and probably a few even rigorously utilize it, but software validation exists on a spectrum ranging from formal verification to nothing at all. Unit-testing tends to reside a lot closer to the empty abyss side of that spectrum in-practice, so what methods and tools can we use to start inching (centimetering, for the internationally inclined) closer to the other side? To get to a point where we're brimming with confidence about our design and implementation? Property-Based Testing can be the next step on that journey, and this month we'll take a look at one of Elixir's PBT frameworks and use it to validate a bit of code.

Elixir Games PDX - You're Getting On My Nerves
Puppet

Bridging the gap between higher-level application development and embedded device deployments is all the rage these days. As is the case with the much of the rest of the Elixir ecosystem, there's a project to help make such ambitions a lot more friendly and inviting to work with (http://nerves-project.org/). This month we'll be taking a look at this project, explore a handful of similar alternative approaches to the same problem, and see if we can get some simple distributed Elixir applications running and communicating as Nerves apps.

If you have any of the supported hardware (referenced below), then by all means bring it with you and we'll see if we can get things working on real hardware. All the organizer's embedded SBCs are Odroid C2's, which aren't Nerves-compatible, so we won't be able to supply hardware for the whole group, but for those that don't have hardware to deploy to we can still build QEMU ARM images and run them in an emulated VM environment.

Erlang-Elixir - Moving Complexity Around
Househappy

Jesse Cook will lead our exploration tonight.

Jesse: A beginner Alchemist who's really enjoying the functional nature of Elixir and the design of the language.

Description: Moving complexity around - What's the best way to provide a unified API in front of some of the worst APIs out there? The tools I reached for are Phoenix, Absinthe for GraphQL and a series of adapters. These adapters utilize both polymorphism and metaprogramming, but was this the right way to do it in Elixir? Let's discuss the overall architecture and the nitty gritty details.

Auto-generated docs from the Erlang AST in Kazoo
Househappy

The Portland Erlang and Elixir User Group's March meeting

The age-old trope of developers being lazy and never writing docs has some basis in reality. What can we do to use the code developers write to create documentation and other assets? I'm not talking about annotations or "special" code comments either - the actual code (well, the AST the compiler creates from the code).

With Kazoo, we have a growing userbase wanting to build their own functionality on top of the platform; yet our docs were lagging, out of date, all over the place, or simply non-existent. Come learn how we are taking docs seriously, jump-started the effort by exploiting patterns in our codebase to auto-generate docs and JSON schemas, and built controls into our CI to hopefully ensure the docs are maintained and up to date.

Bio: Having worked on Kazoo for 7+ years now, James Aimonetti has made it his mission to bring better docs to Kazoo's open-source and commercial users. He wants to spread the gospel to other developers and hopefully provide some ideas for how you can bring docs into your development culture too!

Erlang/Elixir Meetup
Househappy

The Secure Remote Password Cryptor (SRPC) addresses mobile app security in a post web-app world. SRPC provides HTTPS quality security without the explicit transfer of trust inherent in using HTTPS with PKI. SRPC is immune to HTTPS Man-in-the-Middle issues and also provides many features out-of-scope for HTTPS.

SRPC requires a pair of libraries, one on the client device and one on the server. To create an easy way for mobile app developers to try SRPC, I've built a Erlang OTP system that acts as an SRPC tunnel to an "unaltered" HTTP server. The system is comprised of:

  • srpc_lib: Low-level functionality
  • srpc_srv: The SRPC protocol
  • srpc_elli: An Elli layer to expose srpc_srv to an elli app

There are two optional pieces:

  • srpc_elli_proxy: Proxies request to the "unaltered" HTTP server
  • srpc_elli_lager: Lager module

Finally, I have a test system for testing the iOS framework (Android is underway):

  • srpc_elli_test: Test implementation

Presented by Paul Rogers, an independent software engineer with many years of development experience across multiple platforms using a number of different computer languages. He has a Master of Science in Mathematics, which helps him dig into the internals of cryptography, and a Master of Science in Physical Oceanography.

This will likely be a small talk, with room for additional mini talks.

Thesis: An Elixir/Phoenix CMS
Househappy

For the longest time, content management systems have been dominated by PHP projects like WordPress, Drupal, and the like. But for those of us who want to build a Phoenix website, our only recourse has been to build some sort of admin and implement content management from scratch.

Thesis provides an easily bolted on content editing system to your Phoenix website and provides a great developer and user experience. It works with your existing authentication system and database and is only a few lines of code to implement on your site.

Jamon Holmgren created Thesis originally for Rails and then recreated it for Phoenix along with Yulian Glukhenko. He’ll talk about what Thesis is and give a demo of implementing it onto an existing Phoenix website.

Doors open at 6:30, and the talk starts around 7. Pizza and drinks provided by Househappy
