Janrain Headquarters

The Zissou Society for Programming Language Exploration (aka pdxlang) is a general programming language discussion/exploration group. The weird, the offbeat, the little-known, the forgotten programming languages. These are the things we discuss and explore.

Scheduled speakers: Bart Massey talking about m4 and Dave DiNucci talking about ScalPL.

There will be pizza and beer. (If your company wants to sponsor that please get in touch with Matt.)

Luc Perkins has offered to give a talk "Pandoc: the deep dive." - an exploration of how Pandoc works its magic, and why FP is a good choice for that kind of project.

ABOUT THE GROUP: Join programmers, researchers and enthusiasts to discuss functional programming. pdxfunc is a study/user group exploring the world of functional programming based in Portland, Oregon. The group welcomes programmers interested in all functional languages, including Haskell, OCaml, Erlang, Scala and others, as well as using functional techniques in non-functional languages.

Hey folks, it's that time again. We'll have some great beginner friend material courtesy of Rob Norris along with time for general questions and answers for any one who's just getting started with Scala and wants to know how more experienced Scala developers might do things. In addition, Kevin Scaldeferri will be giving a bit of a preview of the material for the talk he'll be giving at Lambdajam (http://lambdajam.com/sessions#scaldeferri) later this summer, covering "using the cake pattern to bridge the divide between unit testing and functional testing." We'll have pizza and we welcome attendees whether you're deep in the Scala world or just passing by and wanting to see what all this functional programming in the OO world is about. 

The monthly meeting of Portland's first JavaScript and ECMAscript users' group. We host presentations and discussions on everything JavaScript-related - including JavaScript frameworks, node.js, CoffeeScript, and whatever else comes up.

Feel free to join our mailing list at http://groups.google.com/group/pdxjs if you too are a JavaScript admirer. Or visit our web site for more information at http://pdxjs.com/.

If you're interested in making a presentation at this or at a future meet-up, please e-mail luc@janrain.com.

We are still looking for presenters for this meet-up, so please contact me if there's something you'd like to share with us!

Come join other Scala fans, whether you're a seasoned oldtimer or complete beginner. We'll have open discussions and a variety of presentations and examples. If you have topics you're interested in hearing more about or something you'd like to give a presentation on, please let us know! Also, feel free to bring code you'd like to show off or get input on from the rest of the group!

This month we will be continuing with our new format with the first hour of the meeting (now starting at 6PM) devoted to newcomers to Scala. If you have questions about getting started with Scala, how to set up a project, or advice on libraries, idioms or whatever, come by and join in. In addition, we have a couple very interesting talks lined up for those of you who want to dive a bit deeper:

• Bryan Armstrong will be present the Spray HTTP library.
• Leif Warner will be giving a talk on the Scalaz Stream library (https://github.com/scalaz/scalaz-stream), a Scala derivative of Edward Kmett's Haskell-based "Machines" library (http://hackage.haskell.org/package/machines).

We'll have pizza available at 6, so if you're planning to join us, come early if you're hungry!

This month, we plan to have talks on:

• Dave Rostron will discuss the new Scala 2.10 reflection library with possible additional material on macros.
• Kevin Scaldeferri will do a walk through of how Gilt Groupe is using SBT to support development of highly-distributed micro-services architecture.
• Bryan Armstrong will be doing a presentation on Spray.

We look forward to seeing you there!

PRESENTATIONS:

• Paul deGrandis on Clojure data structures and reducers. Reducers are based on monoids and protocols, and automatically parallelize folding and mapping on sequences/collections.
• Leif Warner on Idris, a general purpose pure functional programming language with dependent types. "Idris is a language perhaps between Haskell and Scala, but with dependent types. For the most part it looks much like Haskell, only types and values share the same namespace. Other features it offers are things like a simple FFI to C, idiom brackets, and extensible syntax."
• ...and much more!

PRESENTATIONS

• Matt Youell will talk about some of the functional features of C#
• Echo Nolan will talk about functional reactive programming (FRP) and the reactive-banana library for Haskell. More specifically, a series of worked examples in audio synthesis will be explored, showing the expressive power of FRP; hopefully positively answering the questions: "What can FRP do for me?" and "Why should I bother learning yet another abstraction?"
• Lyle Kopnicky will present "SKI School: The Combinator Calculus Demystified", covering the SKI-calculus, Peano and Church numerals, and Iota. Fun math games!
• ...and a lot more!

PRESENTATIONS:

• Lyle Kopnicky will compare and contrast functional reactive programming (FRP) with Max, the visual programming environment for music and video. They exist in the generally distinct worlds of computer science academia and professional production of live music and video. He will also touch on two FRP systems, FrTime and Yampa, as they are very different, but together illustrate the variations on FRP.

• Philip Weaver will talk about performance tuning in Haskell. Laziness in Haskell can lead to performance that is very poor and difficult to understand. He will discuss a recent experience where memory consumption in a TLS implementation was about 100x the expected amount, how he used the GHC profiler to diagnose the problem, and how he used mutable variables and low-level GHC primitives to optimize the algorithm.

PRESENTATIONS:

• Lyle Kopnicky will present the design of a DSL for validating JSON structures from Janrain. It's in Ruby, but functional-inspired.
• Nathan Collins will present on a core language for better records in Haskell. These primitives build a record system with a nice surface language syntax that offers benefits over the traditional Haskell records: first-class records, reusable field names, row polymorphism, direct setting/modifying nested fields, extensible records, polymorphic updates, etc.

PRESENTATIONS:

• Gregory Benison on applying FP techniques for "real world" problems using C: I would like to present an example from my work in protein biochemistry where ideas from functional programming - namely lazy evaluation and immutable data - were important in approaching a "real world" problem. The program I want to discuss is implemented in C and I believe this to be a good example of how ideas from FP can be useful in almost any language.

Hello Portland Android Developers!

Janrain is getting ready to release version 1.0 of the brand new Engage for Android library which includes an abstract and easy to implement user authentication component, as well as an extremely simple to use social sharing UI. In anticipation of our upcoming release, we’re hosting a fast track introduction workshop for interested Android application developers.

Who might be interested: Are you an Android app developer? Are you interested in authenticating your users via Google, Facebook and other identity providers? Perhaps you are interested in enabling social sharing - including tweets and wall posts - directly from your app? Save time and effort, and leverage the benefits of our abstract implementation - the Engage for Android library.

What our product does: The Janrain Engage for Android library provides a system to authenticate Android application users with their existing identity accounts - e.g. Google, Facebook, and Twitter. The library also provides a system to enable your users to share information from your application via their social networking accounts (LinkedIn, Yahoo, Twitter, MySpace and Facebook.)

What our event is: Janrain is hosting a coding workshop at our downtown office. If you are interested in adding our library to your Android application, we invite you to come! (Please bring your laptop.)

At this workshop we’ll walk through everything an Android application developer needs to implement authentication and social sharing with the Engage for Android library, including: IDE integration, Android project configuration, build system troubleshooting, Engage application creation and configuration, authentication system design (including Engage token URLs!), and social sharing invocation.

When our event is: Thursday, June 9 2011, starting 5pm.

Where our event is: The Janrain Office @ 519 SW 3rd Ave, Suite 600, Portland, OR 97204.
