  • 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.

  • '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.

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

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.

  • 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".

Linux and Linux Foundation: Rust, Windows, SystemD and More

  • Linux Developers May Discuss Allowing Rust Code Within The Kernel

    A Google engineer is looking to discuss at this year's Linux Plumbers Conference the possibility of allowing in-tree Rust language support. Nick Desaulniers of Google, who is known for his work on LLVM Clang'ing the Linux kernel and related efforts, is wanting to bring up the matter of in-tree Rust support for the kernel. The extent though of allowing Rust within the kernel isn't clear yet but would likely be very limited.

  • Emulating Windows system calls in Linux

    The idea of handling system calls differently depending on the origin of each call in the process's address space is not entirely new. OpenBSD, for example, disallows system calls entirely if they are not made from the system's C library as a security-enhancing mechanism. At the end of May, Gabriel Krisman Bertazi proposed a similar mechanism for Linux, but the objective was not security at all; instead, he is working to make Windows games run better under Wine. That involves detecting and emulating Windows system calls; this can be done through origin-based filtering, but that may not be the solution that is merged in the end. To run with any speed at all, Wine must run Windows code directly on the CPU to the greatest extent possible. That must end, though, once the Windows program makes a system call; trapping into the Linux kernel with the intent of making a Windows system call is highly unlikely to lead to good results. Traditionally, Wine has handled this by supplying its own version of the user-space Windows API that implemented the required functionality using Linux system calls. As explained in the patch posting, though, Windows applications are increasingly executing system calls directly rather than going through the API; that makes Wine unable to intercept them. The good news is that Linux provides the ability to intercept system calls in the form of seccomp(). The bad news is that this mechanism, as found in current kernels, is not suited to the task of intercepting only system calls made from Windows code running within a larger process. Intercepting every system call would slow things down considerably, an effect that tends to make gamers particularly cranky. Tracking which parts of a process's address space make Linux system calls and which make Windows calls within the (classic) BPF programs used by seccomp() would be awkward at best and, once again, would be slow. So it seems that a new mechanism is called for. The patch set adds a new memory-protection bit for mmap() called PROT_NOSYSCALL which, by default, does not change the kernel's behavior. If, however, a given process has turned on the new SECCOMP_MODE_MMAP mode in seccomp(), any system calls made from memory regions marked with PROT_NOSYSCALL will be trapped; the handler code can then emulate the attempted system call.

  • systemd 246-RC1 Released

    With this being the first systemd release since March, there is a lot in store for the v246 milestone. There are many systemd 246 features including new unit settings, the service manager has support for the cgroup v2 freezer, the CPU affinity setting now supports a NUMA value, systemd.hostname= can be used for setting the hostname from the kernel command line during early boot, hardware database updates, systemd-journald now supports Zstd compression, numerous networkd additions, systemd-cryptsetup now supports activating Microsoft BitLocker volumes during boot, systemd-homed improvements, the new systemd-xdg-autostart-generator, and much more. Just yesterday was one of the latest additions of exposing host OS information to containers.

  • Intel Gen12/Xe Graphics Have AV1 Accelerated Decode - Linux Support Lands

    On top of Intel Gen12/Xe Graphics bringing other media engine improvements and much better 3D graphics support, another exciting element of the next-generation Intel graphics is now confirmed: GPU-accelerated AV1 video decoding! There has been talk of Gen12/Xe supporting AV1 at least on the decode side but a lack of hard information to date. But landing this week in Intel's Media Driver for Linux is indeed AV1 decode wired up for Gen12. This is nice to see happen and a bit of a surprise as so far the Intel Media Driver support matrix has lacked any references to AV1.

  • Four years of Zephyr

    The Zephyr project is an effort to provide an open-source realtime operating system (RTOS) that is designed to bridge the gap between full-featured operating systems like Linux and bare-metal development environments. It's been over four years since Zephyr was publicly announced and discussed here (apparently to a bit of puzzlement). In this article, we give an update on the project and its community as of its v2.3.0 release in June 2020; we also make some guesses about its near future. The authors are both Zephyr developers working for Nordic Semiconductor; Cufí was the release manager for the v2.3.0 release. [...] The Zephyr kernel supports multiple architectures and scheduling algorithms. There are cooperative and preemptive threads, along with facilities for reducing interrupt latencies and guaranteeing the execution of key threads. An optional user mode can use the Memory Protection Units (MPUs) typically present in microcontrollers to isolate and sandbox threads or groups of threads from one another and the kernel. Zephyr supports six major architectures (x86, Arm, ARC, NIOS II, Xtensa, and RISC-V) and also runs in emulation. Both 32- and 64-bit processor support exists for some architectures. Within the Arm architecture, the emphasis has been on the usual 32-bit Cortex-M cores, but experimental support for Cortex-R and Cortex-A (including 64-bit Cortex-A) exists and continues to improve. Beyond "real hardware," Zephyr runs on QEMU, and as an ELF executable. It supports a simulated radio, which can save time and expense when testing and debugging radio frequency (RF) issues. In all, there are upstream support files for over 200 "boards". Zephyr has logging and shell subsystems. These have configurable transports, including traditional serial ports (for both) and over the network (for logging). Logging is optionally asynchronous; in this case, a separate thread actually sends log messages. The logging calls themselves post compact messages to a queue, which can be done quickly, so logging can be done even from within interrupt context. Hardware-specific APIs are built around a lightweight device driver model that is tightly integrated with the kernel. It supports a wide range of peripherals and sensors under this common model. Multiple storage options are available. These range from basic key-value storage optimized for NOR flash to filesystems.

Mozilla Leftovers and Firefox Development

  • Browser Wish List - Tab Splitting for Contextual Reading

    On Desktop, I'm very often in a situation where I want to read a long article in a browser tab with a certain number of hypertext links. The number of actions I have to do to properly read the text is tedious. It's prone to errors, requires a bit of preparation and has a lot of manual actions.

  • Mozilla Privacy Blog: Laws designed to protect online security should not undermine it

    Mozilla, Atlassian, and Shopify yesterday filed a friend-of-the-court brief in Van Buren v. U.S. asking the U.S. Supreme Court to consider implications of the Computer Fraud and Abuse Act for online security and privacy. Mozilla’s involvement in this case comes from our interest in making sure that the law doesn’t stand in the way of effective online security. The Computer Fraud and Abuse Act (CFAA) was passed as a tool to combat online hacking through civil and criminal liability. However, over the years various federal circuit courts have interpreted the law so broadly as to threaten important practices for managing computer security used by Mozilla and many others. Contrary to the purpose of the statute, the lower court’s decision in this case would take a law meant to increase security and interpret it in a way that undermines that goal.

  • Changes to storage.sync in Firefox 79

    Firefox 79, which will be released on July 28, includes changes to the storage.sync area. Items that extensions store in this area are automatically synced to all devices signed in to the same Firefox Account, similar to how Firefox Sync handles bookmarks and passwords. The storage.sync area has been ported to a new Rust-based implementation, allowing extension storage to share the same infrastructure and backend used by Firefox Sync. Extension data that had been stored locally in existing profiles will automatically migrate the first time an installed extension tries to access storage.sync data in Firefox 79. After the migration, the data will be stored locally in a new storage-sync2.sqlite file in the profile directory.

  • Testing Firefox more efficiently with machine learning

    At Mozilla we have around 50,000 unique test files. Each contain many test functions. These tests need to run on all our supported platforms (Windows, Mac, Linux, Android) against a variety of build configurations (PGO, debug, ASan, etc.), with a range of runtime parameters (site isolation, WebRender, multi-process, etc.). While we don’t test against every possible combination of the above, there are still over 90 unique configurations that we do test against. In other words, for each change that developers push to the repository, we could potentially run all 50k tests 90 different times. On an average work day we see nearly 300 pushes (including our testing branch). If we simply ran every test on every configuration on every push, we’d run approximately 1.35 billion test files per day! While we do throw money at this problem to some extent, as an independent non-profit organization, our budget is finite. So how do we keep our CI load manageable? First, we recognize that some of those ninety unique configurations are more important than others. Many of the less important ones only run a small subset of the tests, or only run on a handful of pushes per day, or both. Second, in the case of our testing branch, we rely on our developers to specify which configurations and tests are most relevant to their changes. Third, we use an integration branch. [...] The early results of this project have been very promising. Compared to our previous solution, we’ve reduced the number of test tasks on our integration branch by 70%! Compared to a CI system with no test selection, by almost 99%! We’ve also seen pretty fast adoption of our mach try auto tool, suggesting a usability improvement (since developers no longer need to think about what to select). But there is still a long way to go! We need to improve the model’s ability to select configurations and default to that. Our regression detection heuristics and the quality of our dataset needs to improve. We have yet to implement usability and stability fixes to mach try auto. And while we can’t make any promises, we’d love to package the model and service up in a way that is useful to organizations outside of Mozilla. Currently, this effort is part of a larger project that contains other machine learning infrastructure originally created to help manage Mozilla’s Bugzilla instance.

  • Async Interview #8: Stjepan Glavina

He is one of the primary authors of the various crossbeam crates, which provide core parallel building blocks that are both efficient and very ergonomic to use. He was one of the initial designers for the async-std runtime.

Why Windows Power Users Break Linux

As more people come to Linux, those of us who help the Windows refugees make the switch will need to be very patient with them. The more someone knows about Windows, the more likely it is that they will break Linux. Handing them a Linux laptop and saying, “Here ya go…” is not enough if they are going to succeed. You’re going to have to hold their hand for a while and telling them to “RTFM” will just drive them back to Windows. Understanding why they struggle as much as they do will help you to help them avoid some of the common pitfalls. I specialize in helping people get started with Linux. I’ve helped hundreds of people over the last few years and I can pretty much spot the ones who are going to do well and those who are going to be frustrated. If a client approaches me and they start the conversation with “I’ve been using Windows for 20 years…” I know it’s going to be a bumpy ride. The pattern is always the same: I walk them through an install and all is well for about two weeks and then I get a frustrated message from them about how Linux is stupid and doesn’t work. I know without asking that they’ve broken something major or borked up the whole system. I usually can fix the problem and make a good lesson out of it for them. I have gone so far as to walk them through a second installation from scratch. If the system is totally hosed, that’s the best way to go. Give them a clean slate to work with and hope they learned something. On the other hand, if a client tells me that they know nothing about computers but they need one to get things done like writing documents, spreadsheets, web surfing and email then they usually have zero issues. I get them setup and I don’t hear from them again. I usually contact then after a month or two and they invariably tell me everything is working perfectly. I got a call from a gentleman I hadn’t heard from in a year and a half recently. He said everything was working nicely but he wanted some advice about upgrading his Linux Mint from 17.3 to 18.1 and could I help him get it right. No problem. Wonderful to hear that all is well!

IBM/Red Hat/Fedora Leftovers

  • Making compliance scalable in a container world

    Software is increasingly being distributed as container images. Container images include the many software components needed to support the featured software in the container. Thus, distribution of a container image involves distribution of many software components, which typically include GPL-licensed components. We can't expect every company that distributes container images to become an open source compliance expert, so we need to build compliance into container technology. [...] Package maintainers and package management tools have played an underappreciated role in source availability for over two decades. The focused nature of a package, the role of a package maintainer, and the tooling that has been built to support package management systems results in the expectation that someone (the package maintainer) will take responsibility for seeing that the sources are available. Tools that build binaries also collect the corresponding sources into an archive that can be delivered alongside the binaries. The result is that most people don't need to think about source code availability. The sources are available in the same unit as the delivery of the executable software and via the same distribution mechanism; for software delivered as an RPM, the corresponding source is available in a source RPM. In contrast, there is no convention for providing the source code that corresponds to a container image. The many software components in a container image often include GPL-licensed software. Companies that may not have much experience with distribution of FOSS software may begin distributing GPL-licensed software when they start offering their software in the form of container images. Let's make it straightforward for everyone, including companies who may be new to FOSS, to provide source code in a consistent way.
