  • What is OpenHPC?

    High performance computing (HPC)—the aggregation of computers into clusters to increase computing speed and power—relies heavily on the software that connects and manages the various nodes in the cluster. Linux is the dominant HPC operating system, and many HPC sites expand upon the operating system's capabilities with different scientific applications, libraries, and other tools.

    As HPC began developing, that there was considerable duplication and redundancy among the HPC sites compiling HPC software became apparent, and sometimes dependencies between the different software components made installations cumbersome. The OpenHPC project was created in response to these issues. OpenHPC is a community-based effort to solve common tasks in HPC environments by providing documentation and building blocks that can be combined by HPC sites according to their needs. 

  • Containerd Brings More Container Runtime Options for Kubernetes

    A container runtime is software that executes containers and manages container images on a node. Today, the most widely known container runtime is Docker, but there are other container runtimes in the ecosystem, such as rkt, containerd, and lxd. Docker is by far the most common container runtime used in production Kubernetes environments, but Docker’s smaller offspring, containerd, may prove to be a better option. This post describes using containerd with Kubernetes.

  • Prometheus 2.0 Arrives with a Speedy New Local Storage Engine

    Improved local storage is at the heart of the new release of Prometheus 2.0, according to Fabian Reinartz, a CoreOS software engineer and a core developer of the Prometheus monitoring system.

    With distributed system coordination software such as Kubernetes and Mesos, monitored environments have become increasingly more dynamic, Reinartz pointed out in a blog post. The motioning software needed its own dedicated storage to ensure responsiveness in these dynamic environments.

    Though Prometheus 1.6 introduced auto-tuning capabilities, the team has been working on a more performant time-series database. “It’s just way more reliable and faster. Ideally, you don’t want to have to reconfigure all the time, so Prometheus just responds to change in demands, so there are way fewer knobs to turn for the people running it,” Reinartz said in an interview.

Mozilla Firefox 58

  • Latest Firefox Quantum release available with faster, always-on privacy with opt-in Tracking Protection and new features
    We accept things in the online world that we wouldn’t accept in the physical one. For instance, how would you feel if you popped your head in a store and that store now had the ability to keep sending you flyers even if you didn’t buy anything? Online, we often visit sites that track us, but it isn’t clear when this is happening or how the information is being used. Adding insult to injury, this often invisible tracking actually slows down web pages.
  • Firefox 58 Arrives With Continued Speed Optimizations
    Mozilla has set free Firefox 58.0 today as their latest "Firefox Quantum" release that continues work on being a performant web browser.
  • Firefox Quantum 58 builds on performance gains, improves screenshots tool
    Mozilla is rolling out Firefox Quantum 58.0 for desktop, along with Firefox for Android 58.0. It arrives over two months after the landmark release of Firefox Quantum 57.0. The latest build focuses on performance and security, while an update to Firefox’s user profile feature means it’s no longer backwards compatible with previous versions. Android users also gain the ability to pin favorite websites to their home screen for use like native apps.
  • Firefox 58 Released for Linux, Mac, and Windows
    The Mozilla Foundation has made Firefox 58 files available for download on its official FTP servers. An official announcement will be made later today when the organization will also release the final changelog.
  • Browse without baggage in Firefox: Set Tracking Protection to always on
    We just can’t stop making Firefox faster — and with our most recent release, we also made it easier for you to control how much you’re tracked.
  • Firefox 58: The Quantum Era Continues
    2017 was a big year for Mozilla, culminating in the release of Firefox Quantum, a massive multi-year re-tooling of the browser focused on speed, and laying the groundwork for the years to come. In 2018, we’ll build on that incredible foundation, and in that spirit our next several releases will continue to bear the Quantum moniker. Let’s take a look at some of the new goodies that Firefox 58 brings.

  • Facebook Open Sources Detectron Object Detection
    The way big companies are open sourcing significant AI is both gratifying and slightly worrying. AI is the biggest revolution since we discovered fire and started making tools. FaceBook AI Research has added to the list of what is available by open sourcing its Detectron project.
  • Facebook open-sources object detection research
    Facebook's artificial intelligence research (FAIR) team today announced it would open-source its object detection platform Detectron, as well as the research the team has done on it.
  • Facebook open-sources object detection work: Watch out, Google CAPTCHA
    acebook has brought us one step closer to a Skynet future made a commitment to computer vision boffinry by open-sourcing its codebase for object detection, Detectron. Written in Python and powered by the Caffe2 deep learning framework, the codebase – which implements object-sniffing algos such as Mask R-CNN and RetinaNet – is available under the Apache 2.0 licence.
