  • HP launches OpenSwitch community, new open source NOS

    HP has launched the OpenSwitch community and a new open source network operating system (NOS).

    HP and key supporters, Accton Technology Corporation, Arista, Broadcom, Intel, and VMWare, are delivering a community-based platform that provides developers and users the ability to accelerate innovation, avoid vendor lock-in and realize investment protection as they rapidly build data center networks customized for unique business applications.

  • HP announces refreshed Chromebook 14 w/ full HD display, new Sky Blue color option

    HP today has taken the wraps off a refreshed lineup of Chromebooks. In a press release, the company revealed a new Chromebook 14 lineup with hardware and cosmetic improvements. In addition to a 14-inch model with a 1366×768 display, HP is also offering a model with a full 1080p HD display.

    Both models, however, feature an Intel Celeron N2840 processor coupled with 2GB of RAM and 16GB of internal flash storage. The previous generation model used an Nvidia processor. Battery life is also improved this year, with HP quoting 9 hours of runtime. Though, the higher-resolution HD model will likely clock in a slightly below that.

Raspberry Pi KMS Driver Pull Request Sent For Linux 4.4

Filed under
Linux
Hardware

This Broadcom VC4 DRM/KMS driver has been in the works for a while now with the main hardware target being the Raspberry Pi / Raspberry Pi 2. The Broadcom architectures officially supported by this driver are the bcm2835 and bcm2836. While Eric has also been working on a VC4 Gallium3D driver, this VC4 KMS driver being offered up for Linux 4.4 lacks the kernel bits for hardware acceleration as well as power management. There's other out-of-tree code for that, but it's not ready for mainline with Linux 4.4. Thus with Linux 4.4 on the Pi, you'll just get a nice kernel mode-set powered display with a display plane and cursor.

Displaylink adds Linux support for USB monitors

Hardware

A few weeks ago at IDF, Displaylink released drivers for USB monitors on Linux. This has been something SemiAccurate has been asking them about since, well it has been years now.

The idea is simple, transfer video data over USB rather than a dedicated video port. This requires a bit of compression, CPU load, and of course their proprietary hardware on the monitor side. That isn’t a big deal, the chips are fairly inexpensive and since you are buying a USB monitor or dock, it comes with the device out of the box. On the plus side it means your monitor will work everywhere, or at least it will now.

  • Open source VR from Razer readies for commercial launch, gains more dev support

    Back in January Razer lifted the lid on its highly customizable "Hacker Dev Kit" VR headset and OSVR (Open-Source Virtual Reality) platform, both designed "to set an open standard for virtual reality input devices."

    Now the company has revealed that the consumer version of its headset, the HDK v1.3, will be available for pre-order on October 1, and that its OSVR content discovery platform has launched and can be accessed right away.

  • OSVR's open-source VR headset is slowly taking shape

    The Open Source Virtual Reality (OSVR) headset will get a significant upgrade soon. Gaming peripheral company Razer announced the OSVR program back in January, but the first prototype headset was an underwhelming affair with uncomfortable ergonomics and a so-so display. That wasn't really the point, though. Rather than a single company aiming to dominate the VR market, OSVR is a loose band of hardware and software companies hoping to do for virtual reality "what Android did for mobile."

  • OSVR releasing upgraded VR headset development kit in October
  • The Open Source Virtual Reality movement takes a big jump forward

    As the Virtual Reality gaming market grows, there are some growing efforts that are seeking to be less proprietary, and more inclusive about the process. Open Source Virtual Reality, or OSVR, is a movement that involves not just Razer, but over 230 companies that support the cause.

Hoping that MIAOW is not a catastrophe

An open saucy general-purpose graphics processor (GPGPU) has been unveiled at the Hot Chips event.

The GPGPU is relatively crude and is part of another piece of an emerging open-source hardware platform called MIAOW.

  • The Linux Foundation Announces Session Lineup for ApacheCon(TM) Europe
  • OpenShift Commons Gathering event preview
    We're just two months out from the OpenShift Commons Gathering coming up on November 7, 2016 in Seattle, Washington, co-located with KubeCon and CloudNativeCon. OpenShift Origin is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. Origin adds developer and operations-centric tools on top of Kubernetes to enable rapid application development, easy deployment and scaling, and long-term lifecycle maintenance for small and large teams. And we're excited to say, the 1.3 GA release of OpenShift Origin, which includes Kubernetes 1.3, is out the door! Hear more about the release from Lead Architect for OpenShift Origin, Clayton Coleman.

Security News

  • Report: Linux security must be upgraded to protect future tech
    The summit was used to expose a number of flaws in Linux's design that make it increasingly unsuitable to power modern devices. Linux is the operating system that runs most of the modern world. It is behind everything from web servers and supercomputers to mobile phones. Increasingly, it's also being used to run connected Internet of Things (IoT) devices, including products like cars and intelligent robots.
  • security things in Linux v4.6
    Hector Marco-Gisbert removed a long-standing limitation to mmap ASLR on 32-bit x86, where setting an unlimited stack (e.g. “ulimit -s unlimited“) would turn off mmap ASLR (which provided a way to bypass ASLR when executing setuid processes). Given that ASLR entropy can now be controlled directly (see the v4.5 post), and that the cases where this created an actual problem are very rare, means that if a system sees collisions between unlimited stack and mmap ASLR, they can just adjust the 32-bit ASLR entropy instead.
