Red Hat: libinput, backports, edge computing, survey and more

  • Peter Hutterer: A tale of missing touches

    libinput 1.15.1 had a new feature: it matched the expected touch count with the one actually seen as opposed to the one advertised by the kernel. That is good news for ALPS devices whose kernel driver lies about their capabilities because these days who doesn't. However, in some cases that feature had the side-effect of reducing the touch count to zero - meaning libinput would ignore any touch. This caused a slight UX degradation.

    After a bit of debugging and/or cursing, the issue was identified as a libevdev issue, specifically - the way libevdev replays events after a SYN_DROPPED event. And after several days of fixing things, adding stuff to the CI and adding meson support for libevdev so the CI can actually run a few useful things, it's time for a blog post to brain-dump and possibly entertain the occasional reader such as you are. Congratulations, I guess.

    The Linux kernel's evdev protocol is a serial protocol where all events have a type, a code and a value. Events are grouped by EV_SYN.SYN_REPORT events, so the event type is EV_SYN (0), the event code is SYN_REPORT (also 0). The value is usually (but not always), you guessed it, zero. A SYN_REPORT signals that the current event sequence (also called a "frame") is to be interpreted as one hardware event [0].

  • What is backporting, and how does it apply to RHEL and other Red Hat products?

    Version numbers are important, but aren't always what they seem at first glance. Red Hat, for example, often backports updates to the software we ship in Red Hat Enterprise Linux (RHEL) to maintain the version that we shipped.

    This is a post to follow to Jean-Sébastien Tougne’s post on finding the latest available kernel. Jean-Sébastien’s article was responding to a question on the Red Hat Learning Community, where the poster was seeking the latest version of the kernel for Red Hat Enterprise Linux. That prompted me to write an article that went deeper into the nuance and strategy the Red Hat Enterprise Linux team employs for this to be magically delicious for administrators.

  • The edge is open: Why scale-out computing doesn’t exist without open hybrid cloud

    The past year has seen the rise of applications that push enterprise IT to the (literal) edge, from using autonomous vehicles guided by artificial intelligence (AI) to vast sensor networks that rely on 5G for instant connectivity and emergency reaction times. Whether it's the Internet-of-Things (IoT), fog computing or edge computing, the intent is to bring computing resources like processing power and storage closer to the end user or data source to improve the ability to scale, responsiveness and the overall service experience.

    We can look at the edge as the newest IT footprint, becoming an extension of the data center just like bare-metal, virtual environments, private cloud and public cloud. In a sense, edge computing is a summation of the other four footprints, blending pieces from each to create infrastructure aimed at tackling specific customer demands that traditional IT models cannot address.

  • Enterprise open source software is growing within innovative companies

    Red Hat has been at the forefront of the global open source discussion, fighting for software freedom in the U.S Supreme Court, and offering free tech products for cloud infrastructure, automation, AI, and much more. After conducting research and interviewing IT leaders from around the world, Red Hat released a report examining the state of enterprise open source in 2020.

    950 IT leaders, unaware that Red Hat was the research sponsor, were surveyed about their practices and opinions on enterprise open source software.

  • Multicluster Management and GitOps Workshop

    There’s so much more to come. In the next few weeks, we’ll dive deeper into customer ideas and finish the design thinking process by producing designs, prototyping them, and finally testing their validity.

    We also want you to join us. To help influence the future of OpenShift, sign up to be notified about research participation opportunities or provide feedback on your experience by filling out this brief survey. If you’d like to attend the next workshop, keep an eye on the OpenShift Commons calendar for upcoming events. Feel free to reach out by email if you have any questions.

Amazon and commercial open source in the cloud: It's complicated

  • Amazon and commercial open source in the cloud: It's complicated

    Like many platform operators, Amazon has a love-hate relationship with those hosted on its platform. This is particularly true for open-source software creators, who see their products on offer on Amazon's cloud on terms they are not happy with.

    It's a complicated relationship, which touches upon many aspects of technology, law, and social norms. The issue started becoming more pronounced and entering our turf on Big on Data, as Amazon Web Services (AWS) started offering top open-source data management products on its platform.

    Vendors developing those open source products started accusing AWS of strip mining, i.e., reaping the benefits of the products, without contributing back to their development. Google stepped in to show there is another way of doing business with open source in the cloud. The New York Times stepped in and made this talk of the town.

DownZemAll is an open source download manager for Windows, Linux and macOS

Recently, while casually browsing GitHub, I came across a name that seemed familiar at first; it turned out to be a new download manager called DownZemAll. The program's name is very similar to the popular DownloadThemAll! extension for Firefox, which is what surprised me. The official page reveals that the developer of DownZemAll started the project during the time the legacy add-on stopped working with Firefox Quantum, and seems to have used it as the inspiration to rewrite this application. But that's where the similarities end, because DownZemAll is a desktop program. Let's take a look at it to see how it stacks up. The interface is mostly what you'd expect in a download manager: a menu bar, toolbar, the main pane, but unlike others, DownZemAll has a sidebar too. The options in the side panel are also available from the right-click menu. Read more

You Can Now Buy a PinePhone Preloaded with Ubuntu Touch

Ubuntu Touch, also known by the name UBports, is a community-maintained version of Ubuntu for phones and tablets based on Ubuntu 16.04 LTS. It is a direct continuation of the codebase Canonical cancelled a few years back. From today you (and anyone else interested) can preorder a PinePhone Community Edition with UBports direct from the Pine64 Store. Read more
