  • Daniel Stenberg: Expect: tweaks in curl

    One of the persistent myths about HTTP is that it is “a simple protocol”.

    [...]

    Background

    HTTP/1.1 is designed for being sent over TCP (and possibly also TLS) in a serial manner. Setting up a new connection is costly, both in terms of CPU but especially in time – requiring a number of round-trips. (I’ll detail further down how HTTP/2 fixes all these issues in a much better way.)

    HTTP/1.1 provides a number of ways to allow it to perform all its duties without having to shut down the connection. One such an example is the ability to tell a client early on that it needs to provide authentication credentials before the clients sends of a large payload. In order to maintain the TCP connection, a client can’t stop sending a HTTP payload prematurely! When the request body has started to get transmitted, the only way to stop it before the end of data is to cut off the connection and create a new one – wasting time and CPU…

    “We want a 100 to continue”

    A client can include a header in its outgoing request to ask the server to first acknowledge that everything is fine and that it can continue to send the “payload” – or it can return status codes that informs the client that there are other things it needs to fulfill in order to have the request succeed. Most such cases typically that involves authentication.

  • Environmental activist Shannon Dosemagen joins FSF conference keynote lineup

    Shannon Dosemagen is the second confirmed keynote speaker for the LibrePlanet conference. Dosemagen is the co-founder and current executive director of Public Lab, a nonprofit organization creating local environmental science solutions following the free software philosophy, and winner of the FSF's Award for Projects of Social Benefit. Shannon Dosemagen is an environmental health advocate and a community science champion, and is enthusiastic about free systems and technology that support the creation of a more just and equitable future. She is a previous Fellow at both the Harvard Berkman Klein Center for Internet and Society, and the Loyola University Environmental Communications Institute. During 2020, she will be a Fellow with the Shuttleworth Foundation, working on new concept.

    At LibrePlanet, Dosemagen will discuss her experience democratizing science to address environmental problem-solving. Her experiences and frustrations doing this work are very familiar to the free software community: "The work I do on the environment and health is being increasingly challenged by environmental deregulation and lack of cooperation. We're also seeing heightened pressure to drastically alter how society functions in an effort to curb the climate crisis. This is a profound moment, and critical to address at an event aptly themed 'Free the Future.'"

    "Shannon's work is very important, and is a testament to the success of community collaboration," says Zoë Kooyman, the FSF's program manager. "Public Lab's work towards free hardware solutions is a strong indicator of what the four freedoms can achieve, and how they can work towards a better future outside of software. Shannon is an experienced speaker and organizer, and we are proud to have her keynote at LibrePlanet."

  • TurboTax’s Bid to Buy Free Tax Prep Competitor Might Violate Antitrust Law, Experts Say

    TurboTax, the long-standing dominant player in the tax preparation software market, has recently faced a nascent threat to its lucrative business: A company that specializes in pitching its users financial products has entered the fray with a completely free tax prep service.

    This week, TurboTax’s parent company, Intuit, unveiled a solution to this problem: spending $7.1 billion to buy the rapidly growing upstart, Credit Karma, before it could become a major competitor.

  • Nokia to Weigh Strategic Options as Profit Pressure Mounts [Ed: Microsoft killed Nokia]

    The December announcement that Nokia Chairman Risto Siilasmaa would step down stirred speculation about deeper changes at the company. The firm is in a fierce rivalry with Ericsson and China’s Huawei Technologies Co., as the three dominant players seek to benefit from phone carriers’ investments in next-generation mobile networks.

  • 'Developers have lost hope Microsoft will do the right thing'... Redmond urged to make WinUI cross-platform

    Microsoft's roadmap for developing Windows applications is opposed by some programmers who want to see a cross-platform solution, rather than just being Windows-only.

    Spanish developer José Nieto this week raised an issue on GitHub, stating that WinUI, which Microsoft is positioning as “the native UI platform for Windows 10,” should target not only Windows, but also Linux, Mac, iOS, Android and WebAssembly – this last so it would also run in a web browser.

    This would go against the normal pattern, where a native UI platform is able to take advantage of all the features of the operating system, fits in seamlessly with its look and feel, and is optimized for performance. Supporting cross-platform is a burden that requires compromises.

openSUSE and LibreOffice: Citrix Workspace on openSUSE Tumbleweed, Open Build Service IP Changes, openSUSE + LibreOffice Conference and Navigator Improvements

  • Citrix Workspace on openSUSE Tumbleweed

    Some companies offer their employees to access their corporate computer work space remotely using a remote desktop connection. The company Citrix provides software for such a connection. To connect, the employees need the software Citrix Workspace on their terminal devices. The company provides on their download page also files for Linux including openSUSE. Unfortunately, their version 1912 from 12 December 2019 did not just work on my openSUSE Tumbleweed 64bit computer (and earlier versions I tried neither).

  • New IP addresses for build.opensuse.org

    People using this Open Build Service instance should normally not notice - but if you were crazy enough to add the old IP addresses to some firewall rules or configuration files, please make sure that you update your configuration accordingly.

  • Call for Papers, Registration Opens for openSUSE + LibreOffice Conference

    Planning for the openSUSE + LibreOffice Conference has begun and members of the open-source communities can now register for the conference. The Call for Papers is open and people can submit their talks until July 21.

Mozilla: The Android Firefox Preview, Glean Spyware, and Firefox on Librem 5 (PureOS)

Filed under
Moz/FF
  • Firefox Preview for Android - Interesting

    After I've published my recent series of Firefox articles, mostly the review of versions 71 & 72, and the important essay on why you should be using it as your primary browser, I got a bunch of emails from readers suggesting I take Firefox Preview for a spin. This seems to be the next-gen edition of Firefox for Android, designed to be faster, lighter and more appealing, and hopefully endear a bunch of hearts to Mozilla's effort.

    While I'm not too keen on anything touch, I still want to be able to have a hassle-free, stupidity-free browsing experience anywhere, including the mobile, so I set about testing Firefox Preview. As the test device, I used my Motorola Moto G6 phone, which ought to be fairly representative of the kind of results we should be seeing. Let us begin, then.

  • William Lachance: This week in Glean (special guest post): mozregression telemetry (part 1)

    As I mentioned last time I talked about mozregression, I have been thinking about adding some telemetry to the system to better understand the usage of this tool, to justify some part of Mozilla spending some cycles maintaining and improving it (assuming my intuition that this tool is heavily used is confirmed).

    Coincidentally, the Telemetry client team has been working on a new library for measuring these types of things in a principled way called Glean, which even has python bindings! Using this has the potential in saving a lot of work: not only does Glean provide a framework for submitting data, our backend systems are automatically set up to process data submitted via into Glean into BigQuery tables, which can then easily be queried using tools like sql.telemetry.mozilla.org.

    I thought it might be useful to go through some of what I’ve been exploring, in case others at Mozilla are interested in instrumenting their pet internal tools or projects. If this effort is successful, I’ll distill these notes into a tutorial in the Glean documentation.

  • Desktop Firefox in Your Pocket with the Librem 5

    The first part tells Firefox to use the Wayland display stack instead of X11, which has fullscreen support with keyboard input. Finally --no-remote is a workaround to a Firefox bug. which has already been fixed and will find its way into Debian, as well as the PureOS and the Librem 5 soon.

Ubuntu Switches to a Snap’d Software Store for 20.04

Filed under
Ubuntu

The upcoming Ubuntu 20.04 release will ship with a Snap version of Ubuntu Software app by default.

But while Ubuntu’s default software management tool will become pre-seeded Snap app starting in 20.04 existing Snap builds of Calculator, Characters, and Logs will be reverted to their repo versions.

As noted on Ubuntu Discourse, the ubuntu-desktop and ubuntu-minimal meta-packages now pull in the Ubuntu Software Snap app in place of the regular apt/repo version.

To be clear: this is not a new app store. It is the same Ubuntu Software store as currently shipped, and is still based on GNOME Software. It just packaged as a Snap application.

  • KF6 Progress Report: February Edition

    It’s been two months since my previous KF6 progress report. Clearly an update is long overdue, it’s time to make it happen!

    An actual Qt 6 is not published yet and we didn’t branch for KF6 yet either. Still as can be seen on the KF6 Workboard there are plenty of tasks in our backlog which can be acted upon now. No need to wait to participate, all the work done now will make the transition to KF6 easier later on anyway.

  • This month in KDE Web: January-February 2020

    Following the post about what happened in KDE PIM in November and December by Volker, let’s look into what the KDE PIM community has been up to in the first two months of the new year. In total 23 contributors have made 740 changes.

  • Qt Wayland's Maintainer Is Leaving The Company

    While the Qt5 tool-kit on Wayland is in fairly good shape in recent times, the Qt Wayland module that provides the Wayland platform abstraction and helpers for assembly Qt-based Wayland compositors could run the risk of regressing.

    The future of QtWayland was brought up on the Qt mailing list this week with QtWayland developer Johan Helsing leaving The Qt Company. The hope is there will be no reduced work on Qt Wayland support especially with several companies relying upon it as well as the community, but it was Johan that carried out much of the heavy lifting for this toolkit on Wayland.

  • DXVK 1.5.5 Released With Many Game Fixes

    DXVK 1.5.5 is out this weekend as a big update to this Direct3D-over-Vulkan translation layer widely used by Linux gamers in running Windows games with decent speed.

    DXVK 1.5.5 is a big update contrary to its version number in bringing many game-specific improvements and other fixes. There is also expanded Direct3D support.

  • Direct3D to Vulkan translation layer 'DXVK' version 1.5.5 is out with lots of bug fixes

    Developer Philip Rebohle today announced the release of DXVK 1.5.5, bringing with it plenty of bug fixes for this impressive Direct3D to Vulkan translation layer.

    On the games side, quite a number had specific issues addressed with this release. You should find less issues running: Book of Demons, Close Combat, Cross Racing Championship, Dungeons and Dragons: Temple of Elemental Evil, Elite Dangerous, Evil Genius, F1 2019, Hyperdimension Neptunia U Action Unleashed, Just Cause 1, Lumino City, Saint's Row III / IV, Shade Wrath of Angels, Sins of a Solar Empire, Rocket League and Vampire: The Masquerade Bloodlines which should see improved performance.

    Another tweak was done for Skyrim, this time fixing both crashes and incorrect rendering with the "d3d9.evictManagedOnUnlock" option, they say this is "useful for Skyrim with a large number of mods as an alternative to ENBoost".

  • Robert O'Callahan: Visualizing Control Flow In Pernosco

    In traditional debuggers, developers often single-step through the execution of a function to discover its control flow. One of Pernosco's main themes is avoiding single-stepping by visualizing state over time "all at once". Therefore, presenting control flow through a function "at a glance" is an important Pernosco feature and we've recently made significant improvements in this area. This is a surprisingly hard problem. Pernosco records control flow at the instruction level. Compiler-generated debuginfo maps instructions to source lines, but lacks other potentially useful information such as the static control flow graph. We think developers want to understand control flow in the context of their source code (so approaches taken by, e.g., reverse engineering tools are not optimal for Pernosco). However, mapping potentially complex control flow onto the simple top-to-bottom source code view is inherently lossy or confusing or both. For functions without loops there is a simple, obvious and good solution: highlight the lines executed, and let the user jump in time to that line's execution when clicked on. In the example below, we can see immediately where the function took an early exit.

  • Marco Castelluccio: On code coverage and regressions

    There are two schools of thought when it comes to code coverage: those who think it is a useless metric and those who think the opposite (OK, I’m a bit exaggerating, there are people in the middle…). I belong to the second “school”: I have always thought, intuitively, that patches without tests are more likely to cause postrelease regressions, and so having test coverage decreases risk. A few days ago, I set out to confirm this intuition, and I found this interesting study: Code Coverage and Postrelease Defects: A Large-Scale Study on Open Source Projects. The authors showed (on projects that are very different from Firefox, but still…) that there was no correlation between project coverage and the amount of bugs that are introduced in the project and, more importantly, there was no correlation between file coverage and the amount of bugs that are introduced in the file.

Nvidia GPU Passthrough To Windows VM From Linux Host

Nvidia has now officially enabled GPU passthrough support for Windows virtual machines on GeForce graphics cards. In other words, this effectively means it?s possible to run a Linux machine and then run a virtual Windows machine within it, and hand that unfettered access to a graphics card. This is a big win for those wanting to run Windows games from within a virtual machine on your Linux desktop. They will be able to play Windows-based games using a virtual machine with GPU passthrough enabled. Read more

  • A brief intro to Red Hat OpenShift for Node.js developers – IBM Developer

    Container-based deployment models are the modern way to develop and deliver your applications. The most common tool for building with containers is Kubernetes, an open-source container-orchestration system for automating computer application deployment, scaling, and management. Kubernetes has helped usher in a standardized way to deploy and manage applications at scale, but it can be a sprawling, difficult beast to manage when your application becomes more mature and more complex. A company will need to have a robust DevOps team to manage a full-fledged Kubernetes-based production system. [...] My colleague, JJ Asghar summed it up nicely: “OpenShift provides creature comforts to talk to the Kubernetes “API”—at the same level of robustness—as long as you’re willing to use the opinions OpenShift brings.” The good news? Those opinions are tried and tested, enterprise-ready choices with the backing and support of Red Hat. So, what do Node.js developers need to know about OpenShift deployment? This blog post covers the “what” and “how” of deploying your Node.js application in an OpenShift environment.

  • How Red Hat data scientists use and contribute to Open Data Hub

    Artificial intelligence (AI) and machine learning (ML) drive much of the world around us, from the apps on our phones to electric cars on the highway. Allowing such things to run as accurately as possible takes huge amounts of data to be collected and understood. At the helm of that critical information are data scientists. So, what’s a day on the job look like for data scientists at Red Hat? Don Chesworth, Principal Data Scientist, gives you a glimpse into his day-to-day in a short video (aptly named "A Day in the Life of a Red Hat Data Scientist") that’s now available on our website. Isabel Zimmerman, Data Science Intern, provides a look at some of the tools she uses on the job in "Using Open Data Hub as a Red Hat Data Scientist." We’ll cover some of the highlights in this post.
