Functional Roundup for June 29, 2017

Here are some of the latest updates, projects, talks, articles, and events in the Functional Programming community:


Reactive Stream V.1.0.1-RC1 release

On Thursday, June 29th, Viktor Klang announced the long awaited update of Reactive Streams.

Reactive Streams is set to be included in JDK9 and Viktor wants to make sure everyone tries out the improved TCK, which includes the following alterations:

  • #375 - Fixed potential resource leaks in partially consuming Publisher tests
  • #306 - Renamed untested_spec305_cancelMustNotSynchronouslyPerformHeavyCompuatation to untested_spec305_cancelMustNotSynchronouslyPerformHeavyComputation (yep, that rogue A will get ya)
  • #314 - Allow configuring separate timeout for “no events during N time,” allowing for more aggressive timeouts in the rest of the test suite if required
  • #374 - New test verifying Rule 2.10, in which subscriber must be prepared to receive onError signal without having signaled request before

After checking out the new features and fixes, please send your feedback to the team.

Scala Native 0.3.1

Two weeks ago, Denys Shabalin announced the release of Scala Native 0.3.0 which included a new garbage collector called Immiz. It also featured a lot of library, tooling, and performance improvements as well as a handful of bugfixes.

On Thursday, he published Scala Native 0.3.1. The release fixes issues discovered in 0.3.0 including:

  • #848 - FileWriter fails to create a new file
  • #851 - AbstractList.addAll doesn’t work
  • #863 - Unit tests fail due to new test harness in Travis CI
  • #878 - Make ArrayList throw exceptions as specified in JDK Javadoc

Lightbend and IBM

Lightbend’s having a good week…to say the least. IBM has announced a multi-million dollar investment into the company, to colloborate on an integrated platform for cognitive development.

The platform is designed to act as a single hub where it will be easy to build and deploy AI and “cognitive” applications whether it’s on-premise or cloud-based environments.

Of course, the integrations with IBM Cloud and the Reactive Platform will include focus on CI, data analytics, IoT, security, DevOps, and blockchain, according to the press release.

Basically, to sum it up, Lightbend and IBM just had a very expensive baby.
