Oath’s Top 5 Open Source Goals

Filed under
OSS

For seven years and counting, Gil Yehuda, Senior Director of Open Source at Oath Inc. (which owns the Yahoo and AOL brands), has led the open source program at Yahoo. Now with an expanded scope, he is gearing up to grow his team and improve the program. The company’s formal open source program office serves as a hub to connect all open source activities across the company, he says, but it didn’t start out that way.

As with many other companies, the open source program started informally with a group of diligent engineers and a few legal people. But the ad hoc group soon realized it needed a more formal program if it was going to be able to scale to address more issues and achieve specific business goals. With a formal program in place, they are poised to achieve its goals.

Hands-on: Raspberry Pi Zero 3-Port USB Hub with Ethernet

Filed under
Linux

The Raspberry Pi Zero has been a wonder since it was first introduced. So much power (and so much fun!) in such a small package. Ah, but there was the problem, too -- such a small package, that it didn't have room for very many connectors, and the ones that it had were smaller than the standard-sized connectors on the full-sized Pi models.

The biggest of these problems was with USB connections. The Pi Zero has only one USB port (yeah, I know it looks like there are two, but the other one is the power connection and you can't hijack it), and it is not even a standard Type-A port, it is a microUSB (also known as OTG or 'on the go'). That means that Pi Zero owners who needed to connect USB devices and dongles (who doesn't?) had to buy some kind of micro-to-TypeA adapter cable.

Rugged mobile gateway runs Linux

Filed under
Linux

Artila’s “Matrix-713” mobile IoT gateway runs Linux on a Cortex-A5 ATSAMA5D35, and provides Fast and Gigabit Ethernet, 2x CAN, 2x mini-PCIe, GPS, and an IMU, and supports -20 to 80°C temperatures.

Artila’s Mobile IoT Gateway Matrix-713 follows a similarly headless Matrix-710 embedded computer announced last May, which also runs Linux 4.9 on a 536MHz, Cortex-A5 Atmel ATSAMA5D35 SoC, and shares many of the same features. It’s not a replacement, however, but rather a more advanced, mobile-friendly alternative. (Separately, Artila announced a new Aport-213 (PDF) serial-to-WiFi gateway.)

8 unusual FOSS tools for agile teams

Filed under
GNU

You might be familiar with the expression: So many tools, so little time. In order to try to save you some time, I've outlined some of my favorite tools that help agile teams work better. If you are an agilist, chances are you're aware of similar tools, but I'm specifically narrowing down the list to tools that appeal to open source enthusiasts.

Caution! These tools are a little different than what you may be expecting. There are no project management apps—there is a great article on that already—so there are no checklists, no integrations with GitHub, just simple ways to organize your thoughts and promote team communication.

Security: Meltdown and Spectre Patches

Filed under
Security
  • Linux Mint project advises on Meltdown and Spectre

    The Linux Mint project has released a guide to address the Meltdown and Spectre bugs offering instructions for users on how they should mitigate the holes in their systems. It explains how to tighten up your web browsers and driver software, as well as providing a status update on when we can expect a patch to the kernel.

    The main browser that’s bundled with the operating system is Firefox. The advice is to ensure you update to Firefox 57.0.4, which was released several days ago. As for Chrome and Opera, you should go into the respective flags pages and enable strict site isolation, also called site per process. Google plans to fix the bug next month when it releases the next major edition of Google Chrome. An Opera update will follow.

  • Canonical Releases Ubuntu Kernel and Nvidia Updates to Fix Meltdown and Spectre

    As promised, Canonical released a few moments ago the new kernel and Nvidia updates to address the Meltdown and Spectre security vulnerability on all supported Ubuntu Linux releases.

    The company said last week in a public announcement that it will patch all supported Ubuntu releases against Meltdown and Spectre security vulnerabilities, and the first set of patches are now available in the stable software repositories of Ubuntu 17.10 (Artful Aardvark), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 LTS (Trusty Tahr) to address some of these issues.

  • Linux Mint security notice on Meltdown and Spectre

    A security notice was posted on the official Linux Mint blog on January 9, 2017. It informs users of the Linux distribution about the recently discovered security issues in modern processors called Meltdown and Spectre, and how these affect Linux Mint.

    The notice contains instructions to protect Linux Mint systems from potential attacks that target the vulnerabilities. It covers web browsers, Nvidia drivers, and the Linux kernel.

  • Tails 3.4 Anonymous Live System Released with Meltdown and Spectre Patches

    The Tails development team announced today the release and general availability of the Tails 3.4 amnesic incognito live system, also known as the anonymous live system.

    Tails is a Debian-based live Linux system designed with a single purpose in mind, to hide all your online activity from the prying eyes of the government. For that, it relies on the latest Tor and Tor Browser technologies by allowing users to connect to the Tor anonymous network.

  • Tails 3.4 privacy-focused Linux distro now available with Meltdown and Spectre fixes

    With everything going on in the world these days, it can feel like you are naked when using your computer. If you previously felt safe and secure, these last several years have probably eroded all of your confidence. Between Edward Snowden's revelations and the many vulnerabilities constantly hitting the news, it is tempting to just live in the woods without electricity.

    Before you sell your house, buy a tent, and become a nomad, you should consider a Linux distribution the helps you fight back against evil governments, nefarious hackers, and other bad people. Called "Tails," this Linux-based operating system is designed to be run from a live environment, such as on a DVD or flash drive, so you can hide your tracks and enjoy your God-given right to privacy. Today, version 3.4 becomes available and if you are already a Tails user, you should upgrade immediately. Why? Because it includes kernel 4.14.12 which offers fixes for Meltdown and Spectre (partially).

  • Greg Kroah-Hartman on Meltdown and Spectre Bugs: Go Update Your Linux Kernel

    Renowned Linux kernel developer Greg Kroah-Hartman has published an in-depth article on the status of the Meltdown and Spectre patches in the Linux kernel.

    As you already know, two severe hardware bugs were unearthed last week as the worst chip flaws in the history of computing. Dubbed Meltdown and Spectre, these security vulnerabilities affect us all, and put billions of devices at risk of attacks by allowing attackers to steal your sensitive data that's stored in kernel memory via locally installed apps or on the Web through malicious scripts.

The Combined Impact Of Retpoline + KPTI On Ubuntu Linux

Filed under
Graphics/Benchmarks
Ubuntu

Over the past week I have posted many KPTI and Retpoline benchmarks for showing the performance impact of these patches to combat the Spectre and Meltdown vulnerabilities. But with my testing so far I haven't done any showing the combined impact of KPTI+Retpoline on Ubuntu versus a completely unpatched system. Here are some of those results.

Similar to the Benchmarking Clear Linux With KPTI + Retpoline Support, these tests are similar but with a few different systems and looking at the performance when testing from Ubuntu 17.10. The comparison on each system was to a stock Linux 4.14.0 kernel compared to the Linux 4.14 kernel with the upstream KPTI patches paired with the Retpline v5 patches that have yet to be merged for mitigating Spectre.

With Linux, You Don't Get One Kernel of Truth... You Get Many

Filed under
GNU
Linux

As much as I love to poke at the inner workings of my computer, I'll admit that until recently, I didn't give much thought to which version of the Linux kernel my desktop system was running.

For most desktop users, this isn't all that odd. Compatibility of kernel modules is often critical for servers and production systems, but day-to-day desktop usage doesn't change much from update to update.

Two things motivated me to scrutinize the kernel version more closely: considerations for specific hardware; and a very scary bug recently identified in the Ubuntu distribution's latest release.

Having picked up a lot of useful tips in exploring different kernel versions, I decided to share what I've learned so far.

  • Debbugs Versioning: Merging

    One of the key features of Debbugs, the bug tracking system Debian uses, is its ability to figure out which bugs apply to which versions of a package by tracking package uploads. This system generally works well, but when a package maintainer's workflow doesn't match the assumptions of Debbugs, unexpected things can happen.

  • LXD Weekly Status #29

    And we’re back from the holidays!
    This “weekly” summary is covering everything that happened the past 3 weeks.

    The big highlight was the release of LXD 2.21 on the 19th of December.

    During the holidays, we merged quite a number of bugfixes and smaller features in LXC and LXD with the bigger feature development only resuming now.

    The end of year was also the deadline for our users to migrate off of the LXD PPAs.
    Those have now been fully deleted and users looking for newer builds of LXD should use the official basckport packages or the LXD snap.

  • 7 systems engineering and operations trends to watch in 2018

    Kubernetes domination

    Kubernetes came into its own in 2017 and its popularity will only grow in 2018. Edward Muller, engineering manager at Salesforce, predicts that building tools on top of Kubernetes is going to be more prevalent next year. “Previously, most tooling targeted one or more cloud infrastructure APIs,” says Muller. “Recent announcements of Kubernetes as a Service (KaaS?) from major cloud providers is likely to only hasten the shift.”

  • 2018: The Year of Kubernetes and Interoperability

    On its own, Kubernetes is a great story. What makes it even better is the soaring interoperability movement it’s fueling. An essential part of enabling interoperable cloud-native apps on Kubernetes is the Open Service Broker API. OSBAPI enables portability of cloud services across offerings and vendors. A collaborative project across multiple organizations, including Fujitsu, Google, IBM, Pivotal, Red Hat and SAP, it enables developers, ISVs, and SaaS vendors to deliver services to applications running within cloud-native platforms. In 2017, we saw adoption of the API by Microsoft and Google. Late in the year, Amazon and Pivotal partnered to enable expose Amazon’s services via the broker as well. Red Hat uses it to support the OpenShift marketplace.

  • Linux 4.17 To Likely Include Intel DRM Driver's HDCP Support

    Back in November a Google developer proposed HDCP content protection support for the Intel Direct Rendering Manager (DRM) Linux driver that is based upon their code from Chrome OS / Chromium OS. It looks like that High-bandwidth Digital Content Protection support in the i915 DRM driver will come for Linux 4.17.

    It's too late to happen for Linux 4.16 considering it would be too tardy for it to be comfortably added to DRM-Next. Google developer Sean Paul who has been spearheading this HDMI/DisplayPort HDCP support for the open-source Intel DRM driver believes the code is now ready for merging.

  • Mesa 17.3.2 Release Notes / January 8, 2018

    Mesa 17.3.2 is a bug fix release which fixes bugs found since the 17.3.1 release.

    Mesa 17.3.2 implements the OpenGL 4.5 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 4.5. OpenGL 4.5 is only available if requested at context creation because compatibility contexts are not supported.

  • Mesa 17.3.2 Released With The Latest Stable Fixes

    While Mesa 18.0 will premiere later this quarter as the first feature update of 2018, Mesa 17.3.2 is now available as the second bug-fix release for last quarter's Mesa 17.3 series.

Debian Developers: Google Summer of Code, Quick Recap of 2017

  • RHL'18 in Saint-Cergue, Switzerland
    In between eating fondue and skiing, I found time to resurrect some of my previous project ideas for Google Summer of Code. Most of them are not specific to Debian, several of them need co-mentors, please contact me if you are interested.
  • Quick recap of 2017
         After the Stretch release, it was time to attend DebConf’17 in Montreal, Canada. I’ve presented the latest news on the Debian Installer front there as well. This included a quick demo of my little framework which lets me run automatic installation tests. Many attendees mentioned openQA as the current state of the art technology for OS installation testing, and Philip Hands started looking into it. Right now, my little thing is still useful as it is, helping me reproduce regressions quickly, and testing bug fixes… so I haven’t been trying to port that to another tool yet. I also gave another presentation in two different contexts: once at a local FLOSS meeting in Nantes, France and once during the mini-DebConf in Toulouse, France. Nothing related to Debian Installer this time, as the topic was how I helped a company upgrade thousands of machines from Debian 6 to Debian 8 (and to Debian 9 since then). It was nice to have Evolix people around, since we shared our respective experience around automation tools like Ansible and Puppet.
