We've got a fun meeting coming up this Thursday. The plan is to break into small groups to evaluate various testing frameworks (Sepcs, ScalaTest, JUnit, etc.) and then discuss our findings as a group.

Trenton has graciously set up a GitHub repository with some basic classes to test against and a set of JUnit tests to get started with. It's currently set up with Maven and has the beginnings of an SBT project set up. I'm still working on getting SBT to run the JUnit tests Trenton wrote, but otherwise feel free to clone it and get familiar with it before the meeting:

http://github.com/trenton/TestOfTests

There should also be time to discuss other concerns, ask questions, and the usual sorts of things you might want to do in a group of like-minded techies. If you have ideas for other short discussions you'd like to propose for this meeting or a future meeting, please send them along.

Come join us for another gathering of PDXScala, the Portland Scala users group. This is a casual group focused around the Scala programming language. We welcome both newcomers and experts alike.

Thomas Lockney will be presenting SBT (Simple Build Tool) as a convenient tool for exploring Java libraries with Scala. One of the primary benefits of Scala being available on the JVM is easy integration with existing Java code, but as any Java developer can tell you, it can take a lot of boilerplate to get started exploring a new library. Scala (and SBT) make it possible to shortcut through a lot of this excess code and get right to the heart of the matter.

Brian Panulla has generously agreed to be our first subject for a group code review. He'll be showing his program which converts an XML file to RDF/OWL and we'll have the opportunity, as a group, to look for ways to improve it.

We look forward to seeing you!

We're going to just have a casual meeting this month, so we can hang out, talk about whatever project or bit of code has captured your attention of late, and drink beer. We'll be meeting concurrently with the fine folks at the PDX Weekly Hackathon, so there should be plenty of discussion of quite a varied nature. Feel free to come out and hack on things, of course!

Come join other Scala enthusiasts at our new location graciously hosted by Jive Software. Anything Scala related is open for discussion. We'll have Jesse Hallett discussing how he put together a lambda calculus to learn about Scala's parsing libraries. Leif Warner will also be showing an application he's been developing which uses the Step web framework (a workalike of the the Sinatra framework in Ruby). This app uses Simple Build Tool, Scardf, Jena, TDB, RDF/OWL, graphs and federated queries and is intended to provide an "open source community family tree" of the local Portland-area music scene.

If you have a project or some code you'd like to share (for review or just to look at how you solved an interesting problem) please bring it along. Pizza will be provided by Jive.

It's that time again! It seems to sneak up on me and if I'm not careful, I'll forget to send these notices out entirely. But fate intervened and I was reminded about it just now, so... without further ado... I'm happy to say we have what looks to be a very interesting talk this month being given by Stephen Judkins. Here's the description in his own words:

GOTO Considered Awesome: Delimited Continuations in Scala

Scala 2.8 adds support for delimited continuations, a powerful control-flow abstraction. First, I'll show how the the impressive power offered by continuations can be used for good or evil. I will demonstrate how they can be used to implement GOTO in Scala, then I'll show how a simple, synchronous Scala program can be transformed into a distributed, asynchronous web application that could support millions of concurrent users.

I'll explain what a continuation actually is, and how Scala's are "delimited". I'll step though the code transformations the Scala compiler performs in order to support continuations. I'll show the limitations of Scala's continuation support and how it could be improved. Finally, I'll explain how continuations are a fundamental abstraction upon which many other things can be built.

If you have other topics you'd like to discuss or just want to come hear how others are using Scala, please come join us. There is always plenty of opportunity for open discussions and mini-presentations.

Come join us for another gathering of PDXScala, graciously hosted by Jive Software. We'll be meeting at 7PM, June 17th, and Steven Osborn will be talking about his experiences developing for Android using Scala.

Interested in Android Mobile OS development, but want to be able to program in Scala? Well you can have your cake and eat it too. Steven will give a high level overview of the Android development platform along with his experiences using SBT along the SBT Android plugin to rapidly develop Android applications. We'll cover everything from setting up your project, running your hello world application, and testing.

Steven is the CTO of Urban Airship, a local mobile messaging and content deliver company providing easy to use, cross-platform web services for iPhone, Blackberry and Android. With nearly a decade of experience in the industry he has participated in all stages of a software company from startup to acquisition. Steven enjoys participating in open source development and has contributed significant amounts of code to projects, including Android OpenIntents and IDiB (Identity In The Browser). Steven is also an accomplished Guitar Hero rockstar and believes strongly that ideas are worthless and execution is everything.

If you have other topics you'd like to discuss or just want to come hear how others are using Scala, please come join us. There is always plenty of opportunity for open discussions and mini-presentations.

Come join PDXScala, the Portland, Oregon Scala users group, for a night of geeking and socializing. We'd like to invite any Scala enthusiasts in town for OSCON and the Scala Summit to come join us at the Lucky Lab Brewpub (http://luckylab.com) located at 915 SE Hawthorne Blvd, just a short hop from the Oregon Convention Center, on Monday, July 19th at 7PM.

If possible, please RSVP here. It's not necessary, but helps us figure out how many people to expect.

Come join fellow Scala hackers and enthusiasts. The guest speaker this time will be Peat Bakke, who will be speaking about some of his experiences building a service with Scala. Or in his words:

Scala, Circumflex, and MongoDB

Or, why writing everything from scratch is a great way to learn a language, but a terrible way to be productive.

This is about an ongoing Scala project -- a part of the Capacity product planning and resource management system. We'll be looking at a few parts of the system, a homebrew ORM for MongoDB, and the guts behind the scenes that handles the calculations, and the Circumflex-based JSON web service.

The goal of building these from scratch was to learn, and it continues to be an experiment, so I'm looking forward to everyone's feedback on how to make it better!

Come join fellow Scala hackers and enthusiasts. The guest speaker for this meeting will be Cooper Francis. He's going to cover some of the tricky changes that came in Scala 2.8 (particularly looking at arrays, manifests and implicits) and then do a bit of an exposition of implicits in general and how they can be used to create type classes. This should be a fun talk and I don't doubt we'll all learn something. If any of you have already delved into these changes, please come share your experiences and if you haven't, well... no better time than Thursday night to learn about them!

Once again, our meeting will be at Jive Software (courtesy of Jesse Hallett) and will be starting at 7PM.

We're just going to take it easy this month and have a casual gathering at the Lucky Lab. If weather permits, expect to find us on the back patio.

It's time, once again, for another chance to meet up with fellow Scala developers and enthusiasts (or even the Scala-curious -- you're welcome, too). We'll be meeting this month at the BankSimple offices, located at 334 NW 11th at 7PM this Thursday, March 17th.

I'll give a brief talk about our experiences building Scala code on top of a Clojure framework and some of the trials and tribulations involved in doing so, and Bryan Armstrong will be talk about "Getting back to deterministic resource release by reimplementing 'disposable' semantics and conditionally verifying client code compliance via phantom reference tracking."

Of course, there will also be time for open discussion and questions, possibly even a brief ad-hoc presentation if someone has something they really want to show off.

Kender Elford will talk about doing OpenGL programming with Scala, and Leif Warner will do a short talk on using the Spray library, an asynchronous microframework for building full RESTful servlets on top of Akka actors. The meeting will take place at 7PM at the BankSimple offices (aka, the Urban Airship building), which is located at 334 NW 11th (at the intersection of 11th and Flanders). If you have any trouble finding it, feel free to call me at 971-322-9408. If possible, I'll try to make sure we have some pizza there (anyone want to sponsor this month?). Also, I believe we have a free ticket for OpenSource Bridge to give away.

This will be a pretty casual meeting, but still worthwhile. Bryan Armstrong said he could speak a bit on the new parallel collections support in Scala 2.9. Thomas Lockney may quickly show off a basic Akka demo, but that's looking iffy at this point. If you have anything else you'd like to come talk about, feel free to do so!

If you haven't been to the BankSimple office before, we have a space in the UrbanAirship building.

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 three very interesting talks lined up for those of you who want to dive a bit deeper:

• Anthony Dupre will be talking about more Play Framework goodness including Iteratees and Numeratees.
• Rob Norris will be talking about using the free monad to build pure APIs that manipulate mutable objects.
• 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!

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. 

We'll have Tyler Benson from New Relic giving a talk about the recently released support for Play 2. Thomas will also give a bit of a walk through on setting up a new project with SBT oriented for newcomers. As we've been doing for a couple months now, the first hour of tonight's meeting will be oriented towards people who are new to Scala. If you have questions you'd like to ask about general usage, specific libraries, or overall understanding of the ecosystem, we'll be here to help you find your way. For everyone else, we'll have plenty of extra time tonight for any other discussions and topics, so if you have something you'd like to talk about or code you'd like to show, come prepared! We'll have pizza here at 6, so come early if you're hungry.

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.

This month, we're actually planning something a little bit different form even our new format. I (Thomas Lockney) will be giving a quick introduction to Scalatron (http://scalatron.github.io/), which is a fun way to learn and hone Scala skills in a group environment. The idea is that you build Scala-based "bots" that compete against each other in a common environment. Depending on how the group feels, we can potentially just spend the evening focused on this. But we'll also have time, if people are interested, to explore other topics, as well. We'll have pizza here at 6, so come early if you're hungry.

We look forward to see you all there!

Proposed subjects so far for tonight:

• Rob says he's been working on a port of attoparsec (a fast Haskell parser combinator library) that he could demo for a bit.

• Leif has been incorporating a writer monad into some RDF->JSON code he's updating to output JSON-LD.
