KVM Brings Some Improvements To Linux 3.20

Filed under
Linux

Paolo Bonzini has sent in the KVM pull request for the Linux 3.20 kernel and it includes some interesting changes and features for this important piece of the open-source Linux virtualization stack.

Highlights of the Kernel-based Virtual Machine (KVM) updates for Linux 3.20 include:

- A new optional feature to add a small amount of polling on each executed HLT instruction in the guest, for improving latency by up to 50% for some scenarios. Right now this is a feature that needs to be manually toggled but in the future could be auto-tuned.

Cast your vote in Linus Torvalds' Linux version numbering poll

Filed under
Linux

When Microsoft launched Windows 10 Technical Preview, the name came as something of a surprise; everyone had been, understandably, expecting Windows 9. Over in the world of Linux, as we know, things work a little differently.

The world of Linux-based operating systems is a fragmented one, but Linus Torvalds -- whose loins were partly responsible for giving birth to Linux -- is asking the community how version numbering should be handled moving forward. Should things be kept simple, or should version numbers just keep getting longer, and longer, and longer, and longer?

Linux Kernel-Based Operating Systems Will Have 100% Uptime Thanks to Live Patching

SUSE

Live patching is the hottest trend when we’re talking about Linux kernel-based operating systems. It was created by SUSE, based on KGraft, and distributed in the SUSE Linux Enterprise Server distribution at the end of 2014. Everyone knows that Linux systems don’t require a reboot every time some packages have been updated, except for the kernel. Well, this is not the case anymore with live patching.

Linux-powered quadcopter acts like a smart shuttlecock

On Kickstarter, Zyro is pitching a “DroneBall” quadcopter that runs Linux on Gumstix COMs and acts like a smart aerial ball for multi-player games.

The Zyro DroneBall doesn’t look like a ball — nor does it act like any ball you’ve ever seen that isn’t made of Flubber. The quadcopter can hover, zig, and zag within a virtual aerial arena, mimicking a hockey puck, soccer ball, or an Ultimate Frisbee disc, says Zyro. It can even take the role of an extra player on the field interacting with another DroneBall.

Reactions to “Has modern Linux lost its way?” and the value of simplicity

The best software, whether it’s operating systems or anything else, is predictable. You read the documentation, or explore the interface, and you can make a logical prediction that “when I do action X, the result will be Y.” grep and cat are perfect examples of this.

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.

Programming/Development: ISO C++, Rust, FBGraphics and So-called 'DevOps'

  • Trip Report: C++ Standards Meeting in Rapperswil, June 2018
    A couple of weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Rapperswil, Switzerland. This was the second committee meeting in 2018; you can find my reports on preceding meetings here (March 2018, Jacksonville) and here (November 2017, Albuquerque), and earlier ones linked from those. These reports, particularly the Jacksonville one, provide useful context for this post. At this meeting, the committee was focused full-steam on C++20, including advancing several significant features — such as Ranges, Modules, Coroutines, and Executors — for possible inclusion in C++20, with a secondary focus on in-flight Technical Specifications such as the Parallelism TS v2, and the Reflection TS.
  • Proposal for a staged RFC process
    I consider Rust’s RFC process one of our great accomplishments, but it’s no secret that it has a few flaws. At its best, the RFC offers an opportunity for collaborative design that is really exciting to be a part of. At its worst, it can devolve into bickering without any real motion towards consensus. If you’ve not done so already, I strongly recommend reading aturon’s excellent blog posts on this topic. The RFC process has also evolved somewhat organically over time. What began as “just open a pull request on GitHub” has moved into a process with a number of formal and informal stages (described below). I think it’s a good time for us to take a step back and see if we can refine those stages into something that works better for everyone. This blog post describes a proposal that arose over some discussions at the Mo
  • C gfx library for the Linux framebuffer with parallelism support
    FBGraphics was made to produce fullscreen pixels effects easily with non-accelerated framebuffer by leveraging multi-core processors, it is a bit like a software GPU (much less complex and featured!), the initial target platform is a Raspberry PI 3B and extend to the NanoPI (and many others embedded devices), the library should just work with many others devices with a Linux framebuffer altough there is at the moment some restrictions on the supported framebuffer format (24 bits).

  • Deterministic Firefox Builds
    As of Firefox 60, the build environment for official Firefox Linux builds switched from CentOS to Debian. As part of the transition, we overhauled how the build environment for Firefox is constructed. We now populate the environment from deterministic package snapshots and are much more stringent about dependencies and operations being deterministic and reproducible. The end result is that the build environment for Firefox is deterministic enough to enable Firefox itself to be built deterministically.
  • Brave Launches User Trials for Opt-In Ads That Reward Viewers
    We’ve been busy building our new Basic Attention Token (BAT) platform, which includes a new consent-based digital advertising model that benefits users, publishers, and advertisers. Our first phase started last Fall with the integration of BAT into Brave Payments, and enabled users to anonymously distribute contributions to their favorite publishers and creators.
  • Get Paid For Watching Ads: Brave Browser Announces Opt-in Trials
    Brave, the web browser which garnered a huge fan following, predominantly for its ad blocking feature, and depriving advertisers of confiscating private data by blocking trackers is in the news again. And this time, users can earn some cash. In a blog post, Brave announced that it will be conducting voluntary testing of their new ad model in which they will showcase at least 250 pre-packaged ads to users who will sign up for their early access version. Thus, offering a small amount of money in the form of micropayments.
