J2ObjC is an open source tool created by Google to translate Java code into corrresponding Objective-C code that can be run on iOS. The idea is to reuse Java business code between Android, web and iOS. For the web the translation is done with GWT. This tool does not deal with UI code which needs to be written separately for each platform.
In a recent post on the "swift-evolution" mailing list, Swift creator Chris Lattner outlined a few criteria that will guide Swift 3 definition and made clear that it will bring disruptive changes.
Yahoo has open-sourced DataSketches, a library written in Java for stochastic streaming algorithms. DataSketches is able to perform traditionally expensive operations, like counting distinct occurrences of a variable within a stream, using a fraction of time and memory and with a predictable error margin.
One of the primary design goals of Swift is to allow efficient execution of code while allowing load-time abstraction of implementation, according to a work-in-progress document by Apple. Apple’s document provides information that is relevant to library designers, including Swift’s Standard Libraries, to ensure both backward and forward compatibility.
A growing group of open source project maintainers, including some of the most popular projects on GitHub, have signed an open letter to express their frustration and complaints about what they experience as a feeling of being ignored and being invisible to GitHub’s eyes. InfoQ has spoken with James Kyle, one of the open letter’s initial signees.
Brett Cannon, who is currently in charge of Python's development process, has announced on Python core workflow mailing list that Python will be moving to GitHub. InfoQ has spoken with Brett Cannon to learn more about the benefits that this decision should bring, what the next steps are in the process, and other relevant details.
NativeScript 1.5 has been released. One of the biggest developments is the support for TypeScript, allowing NativeScript users to develop their projects in TypeScript, without the need for TypeScript compilers.
Apple provided new details about Swift 2.2 release process, its goals, and an estimated schedule. Swift 2.2 will be mostly a source-compatible release, while major, breaking changes will be left for Swift 3, Apple say.
We distill here some of the reactions around the web regarding Google’s adoption of OpenJDK for future Android versions.
Swift has overtaken Objective-C in the TIOBE index, an internet-sourced rating of programming languages based on a variety of different sources.
Hacker News has reported on an Android source code commit that suggests that Google’s mobile operating system is switching the implementation of their Java libraries from the original Harmony-based one to OpenJDK. The move has been confirmed by Google to VentureBeat.
A group of researchers from Microsoft has published the paper “IronFleet: Proving Practical Distributed Systems Correct” (PDF) and made available the accompanying source code demonstrating the use of the methodology in machine proving the correctness of a non-trivial distributed system from a safety and liveliness point of view.
The Rust core team has released 1.5, with around 700 changes including the introduction of cargo install and shrinking the metadata size by 20%.
Mozilla has created and open sourced A-Frame, a framework for creating VR scenes for the desktop browser, smartphone and Oculus Rift.
