Intro (0:00)

  • Electric Light Orchestra, anyone?
  • Josh makes everyone say their name in a comedy accent
  • Heather has grown a beard to fit in better with the "1970s Jethro Tull concert" atmosphere at Scala gatherings

  • Scalawags the podcast was born from the Scalawags segment on Java Posse
  • the Scalawags credo: "focus on Scala at length and be idiots"
  • to our listeners: please start your own serious, concise Scala podcast
  • Daniel keeps tweeting about hearing voices; is he going insane?

Conference roundup (7:50)

  • Scala eXchange: Dick is there!
    • which is why English wifi is making him sound like an alien space robot all episode
    • talk videos are up already at:
    • Martin's keynote on solving binary compatibility by introducing a new intermediate format
      • namely syntax trees from after the typer phase of scalac
      • more on this in Scalawags #25
      • Josh knows for whom the "who will do the work?" bell tolls
  • Northeast Scala Symposium (co-organizer, Seth)
  • Scala Workshop (co-organizer, Heather)
    • Portland, Oregon in June
    • growing, a "proper symposium" this year, co-located with PLDI (Programming Language Design and Implementation)
    • academic-ness level to decline from 80/20 to 60/40
    • staging, macros, data structures...
    • it will be like a tornado, but of computer scientists
  • Scala Days, but you know that already

Scala 2.11.3 (20:00)

  • what the hell happened?
  • there was a regression. the release was never announced. we got 2.11.4 instead.
  • there should be Scala 2.11.3 T-shirts for hipsters
  • and actually anyway 2.11.5 is coming in January (not December)
    • there will be sad orphans with no Scala release to fill their stockings
    • badly behaved children get Scala 2.7

sbt 0.13.7 (22:55)

  • we don't need blank lines in our *.sbt files anymore!!!!
    • where should we put them instead?
  • there's a weird bug involving XML
    • Seth is shocked and dismayed to learn that people mix sbt and XML

Scala.js (24:45)

  • Haoyi Li releases new ebook: Hands-On Scala.js
  • there's a book. Scala.js is real now
  • Dick: Scala.js was a hot topic at Scala eXchange
  • Haoyi is busy, he also has a new parboiled2-based Scala parser. and he has a day job.

ScalaMock (27:25)

  • the ScalaMock project is active again
  • Seth doesn't know why Josh thinks he'd be so excited about ScalaMock
    • but sure, mocking is sometimes a good idea and there should be a good library for it
  • why mock, when to mock?
    • external dependencies and services
    • Josh: "mocking makes sense when the cost of writing integration tests is really high..."

Akka 2.3.7 and Akka-HTTP 0.11 are out (31:40)

  • Akka-HTTP is nearing 1.0-RC
    • formerly known as Spray
  • Akka Streams is progressing too
  • Dick has suffered from lack of chunked-encoding support in spray-client
    • but "they've got a story for chunked now... they're getting there"

New NIO layer in scalaz-streams (34:30)

  • announced by Eric Torreborre
    • performance improvement: from minutes to milliseconds
  • streaming is happening stuff

Scala 2.12.0-M1 (35:25)

  • when? we don't know
  • when's the right time for the community to jump on it and start testing?
    • we don't know that either
  • what features will it have?
    • no. you don't understand. this segment of the podcast is completely information-free.
  • we do know that some features will come to 2.11 and 2.12 together
  • do we know which features? of course we don't
  • backported features may be behind flags
  • Josh: if you type -Y, you are in dangerous territory
  • -optimize breaks binary compatibility, so look out for that too

Unfiltered 0.8.3 (40:15)

Octoparts (41:45)

  • http://m3dev.github.io/octoparts/
    • by guys in Japan from M3
  • Dick is very excited because it might have something do with GitHub
    • but it doesn't
  • Octoparts is "an API request aggregation service. It works as a middleware between your frontend and backend services, taking care of request parallelization, response caching, fault tolerance and performance visualization."
  • read the website yourself, we know nothing about this either
    • but we like the purple ghost. and the graphs.

IDEs (Scala IDE, ENSIME, IntelliJ) (44:15)

  • Scala IDE 4.0.0-RC1 is out Dick has been using it
  • it's Eclipse, it uses Scala's presentation compiler, and now it works with multiple versions of Scala (2.10 + 2.11)
    • "exciting but terrifying"
  • as usual Seth won't shut up about Emacs
  • IntelliJ's Scala support has been updated, too
    • Dick's Play projects all broke? "they fixed it", he hastens to say. "they're reacting very quickly"
    • sbt plugin is now "woven into" the Scala plugin

Conclusion (50:40)

  • Scalawags #25 will feature Martin somebody
