  • 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."

  • Apple Won't Allow Movie Villains to Use iPhones
  • 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

    This is the first post in a monthly series about improvements to the KDE websites. I plan to publish it every last Saturday of the month. Since a lot happened in January and I didn’t mention it anywhere, I will also mention those things in this post.

    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".

Hardware: Arduino Nano, Advantech and Adafruit

  • Clockception combines 24 clocks to create one clock

    What if you were to use the hands of a clock not as an individual display, but as part of an array combines together to form digits? That’s the idea behind Clockception by creator “Made by Morgan,” which utilizes 48 servo motors to drive 24 clock-like faces for an 8×3 display. The build uses an Arduino Nano and three servo driver boards to control movement, along with a DS1302 RTC module to track time. The overall clock is constructed out of stained poplar, while the dial assemblies are 3D-printed.

  • Change the volume of any app on your PC with the turn of a knob

    Overall computer volume control is important, but what if you want to get more granular, adjusting sound from various applications individually? Rather than going through a series of menus and on-screen sliders, Ruben Henares’ Maxmix lets you do this on the fly. Based on an Arduino Nano, the simple yet stylish knob takes input from an encoder and button to cycle through and select a program. Just push down and then rotate to turn the volume up or down.

  • QuickFeather Board is Powered by QuickLogic EOS S3 Cortex-M4F MCU with embedded FPGA (Crowdfunding)

    Yesterday, I wrote about what I felt what a pretty unique board: Evo M51 board following Adafruit Feather form factor, and equipped with an Atmel SAMD51 Cortex-M4F MCU and an Intel MAX 10 FPGA. But less than 24 hours later, I’ve come across another Adafruit Feather-sized Cortex-M4F board with FPGA fabric. But instead of using a two-chip solution, QuickLogic QuickFeather board leverages the company’s EOS S3 SoC with a low-power Cortex-M4F core and embedded FPGA fabric.

"ATGC" Aims To Offer Greater Garbage Collection Efficiency For F2FS

F2FS as the Flash-Friendly File-System for Linux continues to see a lot of interesting developments for this file-system beginning to appear on more Android devices and elsewhere given its feature set from flash optimizations to native encryption and compression capabilities. The newest F2FS feature work worth mentioning is support for age-threshold based garbage collection (ATGC). This ATGC garbage collection is geared to improve the efficiency and effectiveness of the background garbage collection for the file-system by evaluating older candidates first based on a defined age threshold.

GNUnet 0.13.0 released

We are pleased to announce the release of GNUnet 0.13.0. This is a new major release. It breaks protocol compatibility with the 0.12.x versions. Please be aware that Git master is thus henceforth INCOMPATIBLE with the 0.12.x GNUnet network, and interactions between old and new peers will result in signature verification failures. 0.12.x peers will NOT be able to communicate with Git master or 0.13.x peers. In terms of usability, users should be aware that there are still a large number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.13.0 release is still only suitable for early adopters with some reasonable pain tolerance.
