Please find below a reminder of our call for the Scala Days 2010 event (http://days2010.scala-lang.org). We welcome proposals from potential speakers. If you would like to talk to people about your framework or tool, or if you would like to share your experience with Scala, this is an opportunity that you should not miss! You may want to describe, for instance, how Scala is being used in your company, or talk about a programming approach that you think should be more widely known. It may also be something as simple as offering a 30-minutes demonstration of your tool, to give people a better idea of what it can do. If you have multiple topics you would feel would be of interest, please feel free to submit multiple proposals. Don't miss this opportunity! Thanks!

Scala 2.8.0 Beta 1 is now available from our Download Page. It includes a huge number of bug fixes with respect to 2.7.7, and many new features. This beta is the foundation for the release of the upcoming final version of 2.8.0, expected in a few months. You can download the Scala 2.8.0 Beta 1 pre-release from: http://www.scala-lang.org/downloads The Scala 2.8.0 Beta distribution ===================================== What is new? ============ The new Scala 2.8 codebase includes the following new fixes and features: - Redesigned collection library The collection library has undergone a complete overhaul for Scala 2.8, offering a more coherent and efficient design, while maintaining virtually complete compatibility with existing sources.

It smoothly integrates features of object-oriented and functional languages. Scala Days is a forum for researchers and practitioners to share new ideas and results of interest to the Scala community. Scala Days 2010 will be held at EPFL in Lausanne, Switzerland, on 15-16 April. CALL FOR SPEAKERS ------------------ As part of Scala Days 2010, we will host a series of Technical Talks, Experience Reports, and Tool Demonstrations. We invite proposals from interested speakers who would like to present their work experience with Scala, or give a demonstration of their project or tool in front of a live audience; who would like to describe the technical inner working of their Scala projects and the tools and techniques they used to achieve their goals, or discuss Scala technical topics of interest to </pre> Antonio Cunei 2010-01-20T17:36:46 http://comments.gmane.org/gmane.comp.lang.scala.announce/169 <pre> After working my way in detective mode through the sources of the Scala compiler, I've put together a write-up [1] to re-launch the "Scala to Java Translator" project. The draft notes summarize (all!) previous work, discuss work-in-progress, and identify open issues. For better results, you may also want to check previous write-ups on the Scala compiler [2]. And, please consider contributing chapters of your own to this developing story.

Integrating them too fast risks instability, and lack of common vision. Integrating them too hesitantly risks stagnation and turning valuable contributors away. To address this problem, we have decided to work with a staged approach, involving a Scala ``incubator'' and a Scala ``greenhouse'' as two stages for extensions and possible future additions to the standard Scala distribution (named ``trunk'' in the following). The incubator was launched some weeks ago by Miles Sabin. It's purpose is to be a highly visible hosting platform for Scala projects that should have widespread appeal and that are possible candidates for future inclusion in a Scala release. Projects in incubator go each at their own pace. Typically each project has one or more owners, but there is no central instance that controls what goes into incubator overall (except for making hosting arrangements).

It's main features include: * 2D rigid body simulation * Simulation of joints * Collision detection and response Important aspects of a developer's point of view are the extensibility and - as the name says - simplicity of the simulator. Unlike many other simulation libraries, SiMS is structured in a way that makes it easy to enhance or add new features to the library. For example, a developer can implement a better collision detection system or create new types of shapes by simply inheriting from classes. Moreover, SiMS is - thanks to Scala - programmed in a very concise manner, thus making the library very simple to understand. The library was created under the terms of a one-year project at school. Having to comply with the evaluation criteria of a project in german language, I had no choice but to do part of the project in that language.

You can see it in action on the Lift wiki here: http://wiki.github.com/dpp/liftweb/how-to-unit-test-lift-snippets-with-a-logged-in-user (scroll at the end for the specs section). - the possibility to display the "plan" of a specification without actually executing it, just to read the text: http://code.google.com/p/specs/wiki/RunningSpecs#Specification_plan In addition to this, specs has been upgraded to use the latest of Scala (2.7.7), ScalaTest (1.0) and ScalaCheck (1.6).

Today is one of those days. My team and I have reported on using compiler plugins to translate database queries into SQL:1999, using a very capabable intermediate language (Ferry) in connection with its very capable optimizer. After following developments in this area for some time, I see some innovative aspects in the proposed approach (e.g., an analysis of integration levels between programming and query languages). So you might want to take a look.

My first attempt to send to scala-announce failed because I wasn't on the list. Trying again...) This morning I deployed a release candidate for ScalaTest 1.0. ScalaTest 1.0 is a major upgrade from the previous released version, 0.9.5. It has many new features. Here are some highlights: - improved JUnit, Ant, and Maven integration - improved integration with JMock, EasyMock, and Mockito - three new core BDD traits: FlatSpec, WordSpec, and FeatureSpec - a GivenWhenThen trait that lets you add documentation to tests that also shows up in reports - several new FixtureSuite traits that facilitate the functional style of passing fixtures into tests - color text output - reports that can be reordered into sequential order after a concurrent run - a Conductor class that facilitates multi-threaded testing of concurrency abstractions - the ability to mark tests as pending, or mark code as pendingUntilFixed - a OneInstancePerTest trait that ensures each test in a suite is run </pre> Bill Venners 2009-10-06T20:06:42 http://comments.gmane.org/gmane.comp.lang.scala.announce/142 <pre>Xus is a peer-to-peer platform in the spirit of JXTA and Pastry. It has a 3 layer architecture (basic packets, 5 types of message routing, and a variety of services) and my automated tests say that layers 1 and 2 apparently work. The goals are simplicity, reliability, security, and ease-of-use. As of this writing, the code base is 1214 lines. Xus does not rely on any third party libraries, except for the Scala 2.8 runtime (I'm using release 18815 at the moment and I periodically update to the latest release).
