  • A broad overview of how modern Linux systems boot
     

    For reasons beyond the scope of this entry, today I feel like writing down a broad and simplified overview of how modern Linux systems boot. Due to being a sysadmin who has stubbed his toe here repeatedly, I'm going to especially focus on points of failure.

  • Separation Architecture Supports Automotive Grade Linux
    Green Hills Software now offers INTEGRITY Multivisor secure virtualization and advanced development tools for Automotive Grade Linux (AGL) on 64-bit automotive grade SoCs. For the first time, AGL applications can be added to automotive systems meeting the highest ISO 26262 safety levels through the INTEGRITY real-time operating system (RTOS). As a result, OEMs can confidently run AGL-based infotainment and connected car applications in secure partitions alongside safety-critical and security-critical functions including instrument clusters, rear-view camera, ADAS, OTA, gateway and V2X. The results are lower system costs, more scalable platforms, shorter development times and lower ASIL certification costs.
  • Second ONAP Open Source Network Automation Release Ships
    The Linux Foundation announced the second software release from the Open Network Automation Platform (ONAP) project, a unified platform for end-to-end, closed-loop network automation Announced last week, ONAP Beijing stems from the melding of two different open source networking automation projects under the direction of The Linux Foundation in March 2017. ONAP focuses on automating virtual network functions in software-defined networking (SDN) and network functions virtualization (NFV) implementations.
  • Linux Projects Driving Demand for IT Pros With Open Source Skills
  • ONF Announces New Reference Designs
    Driving Formation of a New Supply Chain To support operators’ impending deployment of these Reference Designs, a number of tier-1 vendors have joined the efforts as ONF partners to contribute their skills, expertise and technologies to help realize the RDs. Adtran, Dell/EMC, Edgecore Networks and Juniper Networks are actively participating as supply chain partners in this reference design process. Each brings unique skills and complementary competencies, and by working together the partnership will be able to expedite the production readiness of the various solutions.

Games: BATTLETECH, Xenosis: Alien Infection, League of Legends

  • Harebrained Schemes making 'good progress' on the Linux version of BATTLETECH
    While the Linux version of BATTLETECH [Official Site] sadly didn't release with the latest patch, the developer did give it a clear mention.
  • Top-down sci-fi adventure 'Xenosis: Alien Infection' has been fully funded
    As a huge fan of Xenosis: Alien Infection, the top-down survival adventure game from NerdRage Studios, I'm really happy to see it get funded. With around 15 hours left on the Fig campaign, they're sitting pretty at 148% funded with around $37K. That's not bad at all and while it doesn't look like they will hit any interesting stretch-goals, the game itself is great anyway. Check out their latest sneak-peak:
  • Riot changes stance on anti-cheat tech, some Linux users will be able to play League again
    For League of Legends players on Linux, using GPU pass-through technology means they no longer have to say goodbye to Summoner's Rift. Last week Riot Games implemented new anti-cheat technology for the game. This targets all instances of virtualization, or software that acts as if it's hardware, in an attempt to stop users from ruining the game experience for others. Through virtualization, players can create accounts run by bots. This generally results in a ruined experience for anyone in a game with such an account due to the bots playing worse than a human teammate would. Unfortunately for some, the anti-cheat technology also inadvertently locks out users on Linux and other open-source software, like Wine.

Hyperthreading From Intel Seen as Dodgy, Buggy

  • Intel Hyper Threading Performance With A Core i7 On Ubuntu 18.04 LTS
    Following the news yesterday of OpenBSD disabling Intel Hyper Threading by default within its OS over security concerns and plans to disable Simultaneous Multi Threading for other processors/architectures too, here are some fresh Intel HT benchmarks albeit on Ubuntu Linux. The OpenBSD developer involved characterized HT/SMT as "doesn't necessarily have a positive effect on performance; it highly depends on the workload. In all likelihood it will actually slow down most workloads if you have a CPU with more than two cores." So here are some benchmarks using a current-generation Intel Core i7 8700K six-core processor with Hyper Threading.
  • SMT Disabled by Default in -current
  • OpenBSD Will Disable Intel Hyper-Threading To Avoid Spectre-Like Exploits
    OpenBSD, an open source operating system that focuses on security, announced that it will disable Intel’s Hyper-Threading (HT) feature so that attackers can no longer employ Spectre-like cache timing attacks.
  • Intel’s hyperthreading blocked on OpenBSD amid hints of new Spectre-like bugs
    The maintainer of open source Unix-like operating system, OpenBSD, has announced that it will disable hyperthreading on Intel CPUs because of security concerns. It claims that simultaneous multithreading creates a potential new attack vector for Spectre-like exploits, and plans to expand its disabling of multithreading technologies to other chip manufacturers in the near future.
