Open Linux – Beyond distributions, regressions and rivalry

Filed under
GNU
Linux

I love Linux. Which is why, whenever there’s a new distro release and it’s less than optimal (read, horrible), a unicorn dies somewhere. And since unicorns are pretty much mythical, it tells you how bad the situation is. On a more serious note, I’ve started my autumn crop of distro testing, and the results are rather discouraging. Worse than just bad results, we get inconsistent results. This is possibly even worse than having a product that works badly. The wild emotional seesaw of love-hate, hope-despair plays havoc with users and their loyalty.

Looking back to similar tests in previous years, it’s as if nothing has changed. We’re spinning. Literally. Distro releases happen in a sort of intellectual vacuum, isolated from one another, with little to no cross-cooperation or cohesion. This got me thinking. Are there any mechanisms that could help strengthen partnership among different distro teams, so that our desktops looks and behave with more quality and consistency?

KVM & Xen Don't Change Much With Linux 4.15

Filed under
Linux

There are a ton of exciting improvements building up in Linux 4.15, but not too much on the virtualization front.

The Kernel-based Virtual Machine (KVM) work this time around isn't too exciting with no big ticket items debuting for Linux 4.15. KVM for this next kernel release finally has Python 3 support within the Python script that collects runtime statistics from the KVM kernel module. Most of the other work is relatively small additions and fixes. There is some optimizations to ARM's timer handling, PowerPC support for running in a hashed page table MMU mode and single-threaded mode support on POWER9, s390 prep work for exitless interrupts and crypto, and on the x86 front are some fixes, improved emulation in a few areas, and other small work.

  • Linux 4.15 Gets Fixed To Report Current CPU Frequency Via /proc/cpuinfo

    A change recently in the Linux kernel led the CPU MHz reported value via /proc/cpuinfo to either be the nominal CPU frequency or the most recently requested frequency. This behavior changed compared to pre-4.13 kernels while now it's been fixed up to report the current CPU frequency.

  • Linux 4.16 Will Be Another Big Cycle For Intel's DRM Driver

    We are just through week one of two for the Linux 4.15 merge window followed by eight or so weeks after that before this next kernel is officially released. But Intel's open-source driver developers have already begun building up a growing stack of changes for Linux 4.16 when it comes to their DRM graphics driver.

  • Open Source Threat Modeling

    Application threat modeling is a structured approach to identifying ways that an adversary might try to attack an application and then designing mitigations to prevent, detect or reduce the impact of those attacks. The description of an application’s threat model is identified as one of the criteria for the Linux CII Best Practises Silver badge.

Raspberry Pi arrives on PC/104… sort of

Filed under
Linux

Crowd Supply is hosting a “Pi/104” carrier for the RPi Compute Module 3 featuring PC/104 OneBank expansion, a 40-pin RPi header, and -25 to 80°C support.

Here’s something we haven’t seen before. Developer Adam Parker has launched a stackable PC/104 form factor carrier board on Crowd Supply designed to work with the Linux-driven Raspberry Pi Compute Module 3. The industrial-targeted carrier provides -25 to 80°C support and an 8-36V input with screw terminal connector.

    More ARM platform upstreaming has taken place for the Linux 4.15 kernel development cycle among other ARM hardware improvements.

  • Intel Coffee Lake & Cannonlake Thermal Support In Linux 4.15

    While Intel Coffee Lake hardware is shipping already, a few bits of tardy kernel code for these "8th Gen Core" CPUs is only hitting the Linux 4.15 kernel. The Intel DRM driver is most notably enabling Coffee Lake graphics by default in 4.15, but there's also some thermal code now landing among other changes now happening.

    Zhang Rui sent in the thermal updates for Linux 4.15 on Thursday and they include late additions for Coffee Lake but at the same time the relevant additions for Cannonlake that will be shipping in 2018 as the next-gen Intel CPUs.

  • AMDGPU DC Pull Request Submitted For Linux 4.15 Kernel - 132,395 Lines Of Code

Software taking over, but hardware still has a role: Linux expert

Linux

Matthias Eckermann (below, right), director of product management for SUSE Linux Enterprise at the the Nuremberg-based company, said in response to queries from iTWire that software-defined infrastructure would bring about a change in existing business processes, and allow new business processes to be implemented.

But he said this did not necessarily mean that hardware businesses were staring down the barrel at extinction.

  • Why Linus is right (as usual)
    Last year, some security “hardening” code was added to the kernel to prevent a class of buffer-overflow/out-of-bounds issues. This code didn’t address any particular 0day vulnerability, but was designed to prevent a class of future potential exploits from being exploited. This is reasonable. This code had bugs, but that’s no sin. All code has bugs. The sin, from Linus’s point of view, is that when an overflow/out-of-bounds access was detected, the code would kill the user-mode process or kernel. Linus thinks it should have only generated warnings, and let the offending code continue to run.
  • Kube-Node: Let Your Kubernetes Cluster Auto-Manage Its Nodes
    As Michelle Noorali put it in her keynote address at KubeCon Europe in March of this year: the Kubernetes open source container orchestration engine is still hard for developers. In theory, developers are crazy about Kubernetes and container technologies, because they let them write their application once and then run it anywhere without having to worry about the underlying infrastructure. In reality, however, they still rely on operations in many aspects, which (understandably) dampens their enthusiasm about the disruptive potential of these technologies. One major downside for developers is that Kubernetes is not able to auto-manage and auto-scale its own machines. As a consequence, operations must get involved every time a worker node is deployed or deleted. Obviously, there are many node deployment solutions, including Terraform, Chef or Puppet, that make ops live much easier. However, all of them require domain-specific knowledge; a generic approach across various platforms that would not require ops intervention does not exist.

  • Reveal.js presentation hacks
    Ryan Jarvinen, a Red Hat open source advocate focusing on improving developer experience in the container community, has been using the Reveal.js presentation framework for more than five years. In his Lightning Talk at All Things Open 2017, he shares what he's learned about Reveal.js and some ways to make better use of it. Reveal.js is an open source framework for creating presentations in HTML based on HTML5 and CSS. Ryan describes Gist-reveal.it, his project that makes it easier for users to create, fork, present, and share Reveal.js slides by using GitHub's Gist service as a datastore.
  • Font licensing and use: What you need to know
    Most of us have dozens of fonts installed on our computers, and countless others are available for download, but I suspect that most people, like me, use fonts unconsciously. I just open up LibreOffice or Scribus and use the defaults. Sometimes, however, we need a font for a specific purpose, and we need to decide which one is right for our project. Graphic designers are experts in choosing fonts, but in this article I'll explore typefaces for everyone who isn't a professional designer.
