Programming: GCC, LLVM, Rust, Ruby and Python

  • 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.

  • LLVM's OpenMP Runtime Picks Up DragonFlyBSD & OpenBSD Support

    Good news for those using the LLVM Clang compiler on OpenBSD or DragonFlyBSD: the OpenMP run-time should now be supported with the latest development code.

  • 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.

  • Gnocchi: A Scalable Time Series Database For Your Metrics with Julien Danjou - Episode 189

    Do you know what your servers are doing? If you have a metrics system in place then the answer should be “yes”. One critical aspect of that platform is the timeseries database that allows you to store, aggregate, analyze, and query the various signals generated by your software and hardware. As the size and complexity of your systems scale, so does the volume of data that you need to manage which can put a strain on your metrics stack. Julien Danjou built Gnocchi during his time on the OpenStack project to provide a time oriented data store that would scale horizontally and still provide fast queries. In this episode he explains how the project got started, how it works, how it compares to the other options on the market, and how you can start using it today to get better visibility into your operations.

Best Lightweight Linux Distros for Older Computers

tuxmachines.org - Tor, 12/11/2018 - 12:31

Don’t throw away that old Pentium III tower and CRT monitor just yet! While that old laptop in the closet may not be able to run Windows 10 or macOS Mojave, it doesn’t mean it’s destined for the dump.

Many Linux distributions are made specifically for utilizing the ancient, underpowered hardware found in older machines. By installing these lightweight distros, you can breathe new life into an old PC thought to be long past its prime. Here are the best lightweight Linux distros that we’ve picked out from the pile.

  • IoT Gateway uses Ubuntu Core and integrates with AWS IoT Greengrass

    Rigado’s Cascade IoT Gateway running Canonical’s secure operating system Ubuntu Core, has integrated with the newly released Amazon Web Services (AWS) IoT Greengrass features to help give teams an easy-to-use mechanism to get Bluetooth-based data to their cloud applications.

    This new functionality combines the scalability of AWS IoT Greengrass edge computing with the flexibility of Bluetooth connectivity and is provided as part of Rigado’s “edge-as-a-service” Cascade IoT Gateway. The direct connection from the Bluetooth sensor to the cloud is made possible through the integration of AWS IoT Greengrass and Rigado’s Edge Connect on the Cascade gateway. It provides the ability to interact with Bluetooth devices using Rigado REST APIs via AWS Lambda. AWS IoT Greengrass Connectors, a new feature of AWS IoT Greengrass, allows applications to connect to AWS services including Amazon Kinesis Data Firehose, Amazon Simple Notification Service (Amazon SNS), and Amazon CloudWatch. This allows for a full data chain with little to no coding required.

Linux Foundation: LF Networking (LFN), Cloud Native Computing Foundation's (CNCF) KubeCon + CloudNativeCon North America 2018 and the LF Deep Learning Foundation

tuxmachines.org - Tor, 12/11/2018 - 11:26
  • Linux networking project: ‘expose & orchestrate’ to ONAP

    LF Networking (LFN) is the label used by the Linux Foundation to denote the coming together of seven top networking projects.

    In other (arguably more straightforward) words, LFN is an open source networking stack.

    The openly stated aim of LFN is to increase harmonisation across platforms, communities and ecosystems.

    This December 2018 sees new platform releases from ONAP (Casablanca) and OPNFV (Gambia) with additional support for cross-stack deployments across use cases such as 5G, Cross-Carrier VPN (CCVPN), as well as enhancements to cloud-native VPN.

  • Straight outta Linux: Cloud tech conference KubeCon will feature hip-hop star at ‘Ice Cube-Con’

    Will Tuesday be a good day? It will be for those attending KubeCon + CloudNativeCon in Seattle this week if they’re fans of the legendary rapper Ice Cube.

    The cloud-computing startup Mesosphere is taking tech conference musical guests to a fun new level by presenting a side event Tuesday night called Ice Cube-Con. A website dedicated to the performance even reads “Straight Outta KubeCon” in a nod to NWA’s 1988 debut album “Straight Outta Compton.”

  • Celebrating K8s crates inflation rate, Linux mates congregate

    A number of open source types are heading toward Seattle, Washington, on Monday, if they're not already installed there, to attend the Cloud Native Computing Foundation's (CNCF) KubeCon + CloudNativeCon North America 2018 confab.

    The forecast for the cloud-centric event is rain, with widespread Kubernetes. The gathering begins Tuesday, not counting preparatory cocktails. Nonetheless, a press release downpour should arrive on Monday in which less consequential announcements get served as hors d'oeuvres.

    Platform9, a managed hybrid cloud service, plans to tout a handful of corporate customers – Aruba Networks, EBSCO, Hewlett Packard Enterprise (HPE), Juniper Networks, and Snapfish – who've started using its managed Kubernetes service. The idea is that if it's good enough for them, it's good enough for you.

  • Introducing the Interactive Deep Learning Landscape

    The artificial intelligence (AI), deep learning (DL) and machine learning (ML) space is changing rapidly, with new projects and companies launching, existing ones growing, expanding and consolidating. More companies are also releasing their internal AI, ML, DL efforts under open source licenses to leverage the power of collaborative development, benefit from the innovation multiplier effect of open source, and provide faster, more agile development and accelerated time to market.

    To make sense of it all and keep up to date on an ongoing basis, the LF Deep Learning Foundation has created an interactive Deep Learning Landscape, based on the Cloud Native Landscape pioneered by CNCF. This landscape is intended as a map to explore open source AI, ML, DL projects. It also showcases the member companies of the LF Deep Learning Foundation who contribute contribute heavily to open source AI, ML and DL and bring in their own projects to be housed at the Foundation.

Most Secure Operating Systems, VPN for GNU/Linux, and Latest GNU/Linux FUD

tuxmachines.org - Tor, 12/11/2018 - 10:57
  • What’s the most secure operating system?

    Linux has a family of different free versions (known as distributions, or distros) to choose from, based on users’ computer skills. If you’re just getting started, check out Mint or Ubuntu. And because Linux is open-source, users can make copies of modified systems and give them away to friends in need.

  • Choose the Right VPN for Linux in 2019
  • Cryptomining campaign pulls new ‘Linux Rabbit’ malware out of its black hat [Ed: No, it's not ‘Linux Rabbit’ but ‘Weak Password Rabbit’; calling it Linux is rather misleading, distracts from the real problem.]
  • Linux malware: is it so hard to get it right? [Ed: Recognising Catalin Cimpaun for what he really is (and has always been): a clickbaiting troll. For CBS to employ him for ZDNet says a lot about the agenda.]

    Once again, so-called security researchers and tech writers have combined to provide misinformation about trojanised SSH scripts which can be run on a Linux server after said server is compromised through a brute-force attack and root status attained. And they call it Linux malware!
    Security firm ESET and ZDNet writer Catalin Cimpanu have both got it wrong in the past — the latter on numerous occasions as he simply does not seem to understand anything about the Linux security model — but both continue to persist in trying to pursue the topic. ESET has gone in the wrong direction on torrent files and clients too.

    Arguably, there is reason to do so: Linux and malware in the same headline do still serve as some kind of clickbait.

    [...]

    Cimpanu was more descriptive, but again made the same fundamental mistake. Malware can be created for any operating system, but the crucial question is how do you get it onto that system?

    [...]

    Cimpanu's former employer, Bleeping Computer, was also prone to screw-ups of this nature. Here is the editor of Bleeping Computer, Lawrence Abrams, expounding on ransomware targeting Linux servers.

    But then Bleeping Computer is a relatively small operation. One would have thought that ZDNet, which has tons of resources, would have a little more editorial quality control.

Now you can run nginx on Wasmjit on all POSIX systems

tuxmachines.org - Tor, 12/11/2018 - 10:17

Wasmjit team announced last week that you can now run Nginx 1.15.3, a free and open source high-performance HTTP server and reverse proxy, in user-space on all POSIX system.

Wasmjit is a small embeddable WebAssembly runtime that can be easily ported to most environments. It primarily targets a Linux kernel module capable of hosting Emscripten-generated WebAssembly modules. It comes equipped with a host environment for running in user-space on POSIX systems. This allows you to run WebAssembly modules without having to run an entire browser. Getting Nginx to run had been a major goal for the wasmjit team ever since its first release in late July.

GNOME Devs Experiment with a Refreshed GTK & Icon Theme

tuxmachines.org - Tor, 12/11/2018 - 09:27

Now, if you’re a regular reader of this site then may recall our post on a new GNOME icon theme back in July. At the time only a handful of core GNOME apps had been given newly redesigned icons.

Fast forward a season or so and not only is the give-core-apps-new-icons initiative well underway, but the redesign effort has extended to other parts of the desktop experience, including the default theme.

Modernising the look and feel of GNOME apps and the shell is a) a bit overdue and happening as part of a wider update to GNOME design guidelines. The idea is to give the desktop a distinct yet consistent appearance.

Hutterer: Understanding HID report descriptors

LWN.net - Tor, 12/11/2018 - 09:19
For those who would like a deeper understanding of how the human interface device (HID) protocol works, Peter Hutterer has posted a detailed overview. "Originally HID was designed to work over USB. But just like Shrek the technology world is obsessed with layers so these days HID works over different transport layers. HID over USB is what your mouse uses, HID over i2c may be what your touchpad uses. HID works over Bluetooth and it's celebrity-diet version BLE. Somewhere, someone out there is very slowly moving a mouse pointer by sending HID over carrier pigeons just to prove a point. Because there's always that one guy."
