  • HHVM 3.19 Brings CLI Server Mode, Retranslate-All, Performance Boosts

    Facebook developers have put out their latest release of HHVM to empower this PHP interpreter as well as what powers their Hack programming language.

    HHVM 3.19 is the new release this week and it ships with some interesting experimental features. First up, there is a "Retranslate All" feature to re-translate all profiled code into optimized translations after it hits a specified number of requests. This re-translate all can be used for getting better performance, quicker warmups, and more. This experimental feature will likely go on by default in HHVM 3.20.

  • Intel's Beignet Lands LLVM 4.0 Backend Support

    While Intel's Beignet is a terrific project especially when it comes to being a leading open-source OpenCL implementation that works with OpenCL 2.0 on GPUs (something that can't be said for Radeon with its open-source OpenCL stack consistently lacking and Nouveau not really being usable either), the sad part of it is that Beignet is consistently slow in supporting new versions of LLVM.

  • Salaries for storage, networking pros continue to rise

    Though salaries overall remained flat, most tech pros (61 percent) reported receiving a salary increase in 2016 and 9 percent reported a decrease, according to the survey. Increased compensation is the most common motivator employers provided to tech pros in 2016 (18 percent), followed by flexible work location and ability to telecommute (14 percent) and more interesting and challenging assignments (12 percent), according to the survey.

  • QA in Production

    Gathering operational data about a system is common practice, particularly metrics that indicate system load and performance such as CPU and memory usage. This data has been used for years to help teams who support a system learn when an outage is happening or imminent. When things become slow, a code profiler might be enabled in order to determine which part of the system is causing a bottleneck, for example a slow-running database query.

    I’ve observed a recent trend that combines the meticulousness of this traditional operational monitoring with a much broader view of the quality of a system. While operational data is an essential part of supporting a system, it is also valuable to gather data that helps provide a picture of whether the system as a whole is behaving as expected. I define “QA in production” as an approach where teams pay closer attention to the behaviour of their production systems in order to improve the overall quality of the function these systems serve.

Kubernetes, RancherOS, and Servers

  • Kubernetes is king in container survey

    Kubernetes is in, container registries are a dime a dozen, and maximum container density isn't the only thing that matters when running containers.

    Those are some of the insights gleaned by Sysdig, maker of on-prem and in-cloud monitoring solutions, from customers for how they're using containers in 2017.

  • RancherOS 1.0 Container-Optimized Linux Operating System Debuts

  • New Linux SSH server shows off Golang's infrastructure power

    Gravitational, maker of a software-as-a-service support system built with Kubernetes, has released the latest open source iteration of a key part of that system.

    Teleport, an SSH server that provides support teams with a simpler way to remotely manage server clusters, is an example of Google's Go language being used to devise safer but still performant replacements for critical infrastructure.

  • APIStrat Becomes a Linux Foundation and Open API Initiative Event

    The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announces that the API Strategy & Practice Conference has become a Linux Foundation event and will be jointly produced with the Open API Initiative (OAI), a Linux Foundation project. Linux Foundation events are where the world’s leading technologists meet, collaborate and innovate. APIStrat 2017 will take place October 31 – November 2 in Portland, OR.

  • Shrinking the Linux Kernel and File System for IoT

    At last year’s Embedded Linux Conference Europe, Sony’s Tim Bird warned that the stalled progress in reducing Linux kernel size meant that Linux was ceding the huge market in IoT edge nodes to real-time operating systems (RTOSes). At this February’s ELC North America event, another figure who has long been at the center of the ELC scene -- Free Electron’s Michael Opdenacker -- summed up the latest kernel shrinkage schemes as well as future possibilities. Due perhaps to Tim Bird’s exhortations, ELC 2017 had several presentations on reducing footprint, including Rob Landley’s Tutorial: Building the Simplest Possible Linux System.

    Like Bird, Opdenacker bemoaned the lack of progress, but said there are plenty of ways for embedded Linux developers to reduce footprint. These range from using newer technologies such as musl, toybox, and Clang to revisiting other approaches that developers sometimes overlook.

    In his talk, Opdenacker explained that the traditional motivator for shrinking the kernel was to speed boot time or copy a Linux image from low-capacity storage. In today’s IoT world, this has been joined with meeting the requirement for very small endpoints with limited resources. These aren’t the only reasons, however. “Some want to run Linux as a bootloader so they don’t have to re-create bootloader drivers, and some want to run to the whole system in internal RAM or cache,” said Opdenacker. “A small kernel can also reduce the attack surface to improve security.”

  • SDN dilemma: Linux kernel networking vs. kernel bypass

    If we've learned anything in the technology business in the last 25 years, it would be to never underestimate the Linux kernel. Why, then, have so many networking companies been so eager to bypass the Linux kernel -- or more specifically, the Linux kernel networking stack? What could be so wrong with the networking packet arteries in the Linux kernel that motivates so many of us to bypass them?

    There are two main reasons. First, the kernel networking stack is too slow -- and the problem is only getting worse with the adoption of higher speed networking in servers and switches (10GbE, 25GbE, and 40GbE today, and rising to 50GbE and 100GbE in the near future). Second, handling networking outside the kernel allows for plugging in new technology without the need to change core Linux kernel code.

  • Kubuntu 17.04 Debuts with KDE Plasma 5.9 and Folder View from Plasma 5.10, More

    Kubuntu 17.04 was also released today as part of the Ubuntu 17.04 (Zesty Zapus) operating system, and since it's an official flavor, we're gonna take a quick look at its new features.

    Kubuntu 17.04 debuts with the latest, new generation KDE Plasma 5.9 desktop environment customized with some of the goodies coming to the KDE Plasma 5.10 release next month, such as the Folder View instead of the Desktop widget that was used in all previous Kubuntu releases.

  • Ubuntu Budgie 17.04 Is Out as Official Ubuntu Flavor with Budgie 10.2.9 Desktop

    Ubuntu Budgie 17.04 launched today as an official flavor of the popular Ubuntu Linux operating system as part of the Ubuntu 17.04 (Zesty Zapus) operating system release.

    Until today, Ubuntu Budgie was known and distributed as budgie-remix, so this is its first official release as an Ubuntu flavor endorsed by Canonical. Because of this, the Ubuntu Budgie team had a lot of work on their hands during the past six months to remove everything related to the old budgie-remix name, as well as to made other necessary changes.

  • Ubuntu GNOME Will No Longer Be A Separate Flavor

    We told you last week that development of the Vivaldi 1.9 web browser kicked off in style with the first snapshot, which brought numerous improvements to existing features, as well as some new ones.

    At the request of many users, Vivaldi 1.9 will let you shuffle the order of your extensions, and today's Vivaldi 1.9.811.13 snapshot is here to make it easier to fine tune screenshots taken with the built-in screenshot tool, but also to improve the URL autocomplete functionality and the Chromecasting Tab.

  • Google deprecates Octane JavaScript benchmark, because everyone is basically cheating

    Google has announced that its widely used Octane JavaScript benchmark is being retired, with Google saying that it's no longer a useful way for browser developers to determine how best to optimize their JavaScript engines.

    Octane was developed for and by the developers of V8, the JavaScript engine used in Chrome. It was intended to address flaws in the earlier SunSpider benchmark, developed by Apple's Safari team. SunSpider's tests were all microbenchmarks, sometimes testing something as small as a single operation performed thousands of times. It wasn't very representative of real-world code, and it was arguably being gamed, with browser vendors introducing optimizations that were aimed primarily, albeit not exclusively, at boosting SunSpider scores. This was being done even when those optimizations were detrimental to real-world performance, because having a good score carried so much prestige.

  • Chrome 59 To Support Headless Mode

    Chrome 59 stable isn't expected until early June, but when this release comes it will bring with it an interesting feature: a headless mode.

    Chrome's headless mode is made for headless/server environments, such as where you may automatically want to be capturing screenshots of rendered pages, etc. This is very practical for automated testing. Or there's the use-case of just wanting to interact with the DOM but not caring about presenting the contents on any connected physical display.
