  • Networking in Berlin: Qt World Summit 2018

    At our little booth we showcased Plasma running on a variety of devices, ranging from a Nexus 5X running Plasma Mobile through two ARM laptops to the powerful KDE Slimbook. Plasma was praised for its performance and reliability and since the focus of the event was mostly on embedded systems, we could easily demonstrate with our selection of devices that Plasma and the KDE Frameworks are a viable option for an endeavor in this area, too.

    It was very interesting to see the diverse set of people presenting their products and roaming the stalls, to see where Qt is in use today without you even realizing. We were approached by several companies evaluating using KDE Frameworks in their products and also tried to lay a foundation for an eventual partnership. And then there was Daimler who just parked an A-Class in the hallway, whose MBUX infotainment system is also powered by Qt.

  • Vincent Sanders: A very productive weekend

    I just hosted a NetSurf Developer weekend which is an opportunity for us to meet up and make use of all the benefits of working together. We find the ability to plan work and discuss solutions without loosing the nuances of body language generally results in better outcomes for the project.

    [...]

    We rounded the Saturday off by going out for a very pleasant meal with some mutual friends. Sunday started by adding a bunch of additional topics to consider and we made good progress addressing these.

    We performed a bug triage and managed to close several issues and commit to fixing a few more. We even managed to create a statement of work of things we would like to get done before the next meetup.

    My main achievement on the Sunday was to add WEBP image support. This uses the Google libwebp library to do all the heavy lifting and adding a new image content handler to NetSurf is pretty straightforward.

  • First LibreOffice Asia Conference to Take Place May 25-26, 2019 in Tokyo, Japan

    The Document Foundation published today more information on when and where the first ever LibreOffice Asia Conference event will take place this year.

    LibreOffice Asia Conference 2019 will be the project's first conference event to take place in a country in the Asia region where the free and open source software movement is rapidly growing. The Document Foundation decided it's time to put together a conference in Asia after the massive success of the LibreOffice Conference Indonesia 2018 event.

    "It’s a real leap of faith," says Franklin Weng, an Asian member in the Board of Directors of The Document Foundation. "Asia is a rapidly growing area in adoptions of ODF and LibreOffice, but our ecosystem for LibreOffice and FOSS has not been good enough yet. In this conference, we’re not only trying to make the FOSS ecosystem in Asia more healthy but also to encourage Asian community members to show their potential.”

Programming: RenPyWeb, OpenCL 2.2-10, x86 vs. ARM for Web Crawling in Python

Filed under
Development
  • RenPyWeb - Ren'Py in your HTML5 web browser

    I like the Ren'Py project, a popular game engine aimed at Visual Novels - that can also be used as a portable Python environment.

    One limitation was that it required downloading games, while nowadays people are used to Flash- or HTML5- based games that play in-browser without having to (de)install.

    Can this fixed? While maintaining compatibility with Ren'Py's several DSLs? And without rewriting everything in JavaScript?
    Can Emscripten help? While this is a Python/Cython project?
    After lots of experimenting, and full-stack patching/contributing, it turns out the answer is yes!

  • OpenCL 2.2-10 Released With Fixes

    While "OpenCL-Next" will hopefully be on track for releasing later this year as the next big update to OpenCL, OpenCL 2.2-10 was released today by The Khronos Group as the latest maintenance update to the nearly two year old OpenCL 2.2 specification.

    OpenCL-Next can't come soon enough to hopefully bolster OpenCL GPU programming adoption and OpenCL 2.2 showing its age with the provisional specification for it approaching three years old. With today's OpenCL 2.2-10 update there are various fixes to community reported problems. Also, the KHR OpenCL extensions have been folded into the extensions specification.

  • SPEED TEST: x86 vs. ARM for Web Crawling in Python

    Can you imagine if your job was to trawl competitor websites and jot prices down by hand, again and again and again? You’d burn your whole office down by lunchtime.

    So, little wonder web crawlers are huge these days. They can keep track of customer sentiment and trending topics, monitor job openings, real estate transactions, UFC results, all sorts of stuff.

    For those of a certain bent, this is fascinating stuff. Which is how I found myself playing around with Scrapy, an open source web crawling framework written in Python.

Red Hat: Dstat, KubeVirt, Openwashing Banks and OpenShift 4

Filed under

  • Implementing Dstat with Performance Co-Pilot

    Dstat is a beloved tool by many, and a staple when diagnosing system performance issues. However, the original dstat is no longer actively developed. This poses an immediate problem for distributions like Fedora moving to a Python 3 stack, as it lacks a Python 3 implementation (both the tool itself, and its many plugins). It is also problematic in that the plugin system was relatively simplistic and in need of a significant redesign and rewrite to add new desired features.

  • Re-Imagining Virtualization with Kubernetes and KubeVirt – Part II

    KubeVirt exposes a VirtualMachine entity in Kubernetes. This entity is persistent and defines the configuration of a virtual machine. This allows one to create, edit, start, stop, and start again a virtual machine (which one cannot do with a Kubernetes Pod). When the virtual machine is started, a VirtualMachineInstance is created, manifesting in Pod and Container in which the virtual machine runs.

    The VirtualMachine entity allows one to define virtual machines “the way you would expect it” from a virtualization expert’s perspective. You can name them, describe the virtual hardware devices, define multiple disks and networks.

    Expect to find your regular virtualization features here: CPU, memory, NUMA, CPU pinning, hugepages, CPU model selection, virtio-rng, memory overcommit, custom SMBIOS, cloud-init, boot order, serial console, graphical (VNC) console, custom PCI addresses for virtio devices, I/O threads, guest agent integration, and more being worked on.

  • Why agile integration is key for open banking

    Many banks are striving to be more agile in their operations, their business practices, and even in their ability to innovate to deliver new products and services. With greater agility, banks can better meet the demands of today’s digital-savvy customers and excel in an increasingly competitive market. Initiatives like open banking can help facilitate that agility.

    Open banking uses open application programming interfaces (APIs) for third party developers, gives users greater transparency, and provides a model for the use of open source to build out solutions. We think that agile integration – bringing together containers, distributed integration, and APIs – is the best path to deliver open banking.

  • OpenShift 4: A NoOps Platform

    In the previous post I described the goals that helped shape the OpenShift 4 vision. We want to make the day to day of software operations effortless – for operations teams and for developers. How do we make that goal – a NoOps platform for operations – a reality? What does “NoOps” mean in this context?

    At a ten thousand foot level, “Serverless” or “NoOps” for developers is characterized by tools and services that hide or minimize the operational burden from the developer.

    [...]

    That is why I am happy to announce the Developer Preview of OpenShift 4 is now available for public trial. This is a sneak peek of the next version of OpenShift, with an easy to use installer for starting a cluster on AWS on top of Red Hat CoreOS. The preview requires only credentials to an AWS account to provision infrastructure and a set of credentials to access the images for the preview.

Intel Preparing The Linux Kernel For Cascade Lake AP Multi-Die Support

Filed under
Linux
Hardware

Intel developers have begun posting their Linux kernel patches for enabling multi-die/package topology support to the Linux kernel as part of their Cascade Lake AP upbringing.

Cascade Lake "Advanced Performance" is a multi-chip package of multiple Cascade Lake dies, expected to be up to 48 cores / 96 threads per package and twelve DDR4 memory channels. Cascade Lake SP and Cascade Lake X Linux support already has been in order -- or at least appears to be based upon previous commit activity -- while Cascade Lake AP is taking some additional work due to the new multi-die design. Cascade Lake dies are connected via Ultra Path Interconnect (UPI) links.

Red Hat on Middleware, RHEL AUDITD, and More Security Issues

  • Open Outlook: Middleware (part 1)

    Middleware, both as a term and as a concept, has been around for decades. As a term, like other terms in the Darwinian world of IT jargon, it has followed a typical fashion lifecycle and is perhaps somewhat past its apogee of vogue. As a concept, however, middleware is more relevant than ever, and while a memetic new label hasn't quite displaced the traditional term, the capabilities themselves are still very much at the heart of enterprise application development.

    Middleware is about making both developers and operators more productive. Analogous to standardized, widely-used, proven subassemblies in the manufacture of physical goods such as cars, middleware relieves developers from "reinventing the wheel" so that they can compose and innovate at higher levels of abstraction. For the staff responsible for operating applications in production, at scale, with high reliability and performance, the more such applications use standardized middleware components and services, the more efficient and reliable the running of the application can be.

Using Clear Linux As A Desktop Linux Distribution - It Works Well But With Some "Papercuts"

Filed under
Linux

While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.

While we've been benchmarking with Clear Linux for years, only over the past year or two have they really beefed up their bundles around the desktop and make it more appealing for desktop use along with support for Flatpaks, supporting the other DRM/Mesa drivers besides just Intel graphics, delivering a great GNOME Shell experience where as originally they defaulted to Xfce, and overall improving the experience for more use-cases. And, yes, it's even possible to run Steam on Clear Linux.

  • Reproducible Builds: Weekly report #199

    strip-nondeterminism is our tool that post-processes files to remove known non-deterministic output. This week, Chris Lamb adjusted its behaviour to deduplicate hardlinks via stat(2) before processing to avoid issues when handling files in parallel; as the per-filetype handlers are yet currently guaranteed to be atomic, one process could temporarily truncate a file which can cause errors in other processes operating on the “same” file under a different pathname. This was thus causing package build failures in packages that de-duplicate hardlinks in their build process such as the Debian Administrator’s Handbook (#922168).

  • Register Transfer Language for CRuby

    For the last two years, I have been trying to improve CRuby performance. I have been working simultaneously on two major fronts: introducing register transfer language (RTL) for the CRuby virtual machine (VM) and just-in-time (JIT) compilation. For background on the goal of having Ruby 3 be 3 times faster than version 2 (3X3), see my previous article, “Towards the Ruby 3×3 Performance Goal“.

    The JIT project (MJIT) is advancing successfully. The JIT approach and engine I proposed and implemented has been adopted by the CRuby community. Takashi Kokubun hardened the code and adapted it to the current CRuby stack machine and recently MJIT became an experimental feature of the CRuby 2.6 release.

    Introducing a Register Transfer Language (RTL) to the CRuby VM turned out to be an even harder task than introducing the initial JIT compiler. The required changes to the VM are far more invasive than the ones needed for the JIT compiler.

  • Template meta-programming: Some testing and debugging tricks

    There are only a few things more fun in this world than doing template meta-programming (TMP) and reading all those long poems that the compiler writes out when we make even the smallest mistake.

    While we don’t usually welcome these messages, there are ways to make them useful.

    One of the main causes of errors in TMP code are unexpected types – types that the compiler is deducing instead of the types that we expect it to deduce.

    This results in error messages occurring in seemingly random places in our code.

  • Open Science, Open Source and R

    Psychology changed forever on the August 27, 2015. For the previous four years, the 270 psychologists of the Open Science Collaboration had been quietly re-running 100 published psychology experiments. Now, finally, they were ready to share their findings. The results were shocking. Less than half of the re-run experiments had worked.

    When someone tries to re-run an experiment, and it doesn't work, we call this a failure to replicate. Scientists had known about failures to replicate for a while, but it was only quite recently that the extent of the problem became apparent. Now, an almost existential crisis loomed. That crisis even gained a name: the Replication Crisis. Soon, people started asking the same questions about other areas of science. Often, they got similar answers. Only half of results in economics replicated. In pre-clinical cancer studies, it was worse; only 11% replicated.

GCC 8.3 Released and GCC 9 Plans

  • GCC 8.3 Released
    The GNU Compiler Collection version 8.3 has been released. GCC 8.3 is a bug-fix release from the GCC 8 branch containing important fixes for regressions and serious bugs in GCC 8.2 with more than 153 bugs fixed since the previous release. This release is available from the FTP servers listed at: http://www.gnu.org/order/ftp.html Please do not contact me directly regarding questions or comments about this release. Instead, use the resources available from http://gcc.gnu.org. As always, a vast number of people contributed to this GCC release -- far too many to thank them individually!
  • GCC 8.3 Released With 153 Bug Fixes
    While the GCC 9 stable compiler release is a few weeks away in the form of GCC 9.1, the GNU Compiler Collection is up to version 8.3.0 today as their newest point release to last year's GCC 8 series.
  • GCC 9 Compiler Picks Up Official Support For The Arm Neoverse N1 + E1
    Earlier this week Arm announced their next-generation Neoverse N1 and E1 platforms with big performance potential and power efficiency improvements over current generation Cortex-A72 processor cores. The GNU Compiler Collection (GCC) ahead of the upcoming GCC9 release has picked up support for the Neoverse N1/E1. This newly-added Neoverse N1 and E1 CPU support for GCC9 isn't all that surprising even with the very short time since announcement and GCC9 being nearly out the door... Arm developers had already been working on (and landed) the Arm "Ares" CPU support, which is the codename for what is now the Neoverse platform.
