GCC 9 Guts Out The PowerPC SPE Support
It should come as no surprise since it was deprecated in this year's GCC 8 release, but the PowerPC SPE code has been removed.
This isn't to be confused with conventional POWER/PowerPC but rather PowerPC SPE that is for the "Signal Processing Engine" on older FreeScale/IBM cores like the e500. It's not all that important these days and doesn't affect newer versions of the 64-bit Power support.

Nick Cameron: Rust in 2022
In case you missed it, we released our second edition of Rust this year! An edition is an opportunity to make backwards incompatible changes, but more than that it's an opportunity to bring attention to how programming in Rust has changed. With the 2018 edition out of the door, now is the time to think about the next edition: how do we want programming in Rust in 2022 to be different to programming in Rust today? Once we've worked that out, lets work backwards to what should be done in 2019.
Without thinking about the details, lets think about the timescale and cadence it gives us. It was three years from Rust 1.0 to Rust 2018 and I expect it will be three years until the next edition. Although I think the edition process went quite well, I think that if we'd planned in advance then it could have gone better. In particular, it felt like there were a lot of late changes which could have happened earlier so that we could get more experience with them. In order to avoid that I propose that we aim to avoid breaking changes and large new features landing after the end of 2020. That gives 2021 for finishing, polishing, and marketing with a release late that year. Working backwards, 2020 should be an 'impl year' - focussing on designing and implementing the things we know we want in place for the 2021 edition. 2019 should be a year to invest while we don't have any release pressure.
To me, investing means paying down technical debt, looking at our processes, infrastructure, tooling, governance, and overheads to see where we can be more efficient in the long run, and working on 'quality of life' improvements for users, the kind that don't make headlines but will make using Rust a better experience. It's also the time to investigate some high-risk, high-reward ideas that will need years of iteration to be user-ready; 2019 should be an exciting year!

A Java Developer Walks Into A Ruby Conference: Charles Nutter’s Open Source Journey
As a Java developer, Nutter began looking for an existing way to run Ruby within a Java runtime environment, specifically a Java virtual machine (JVM). This would let Ruby programs run on any hardware or software platform supported by a JVM, and would facilitate writing polyglot applications that used some Java and some Ruby, with developers free to choose whichever language was best for a particular task.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
