GCC 9 Drops Support For Older ARM Microarchitecture Versions

Filed under
Development
GNU

Next year's GCC 9 compiler release will be eliminating support for older ARM versions.

Fortunately, ARMv7 and newer is still in great shape given they are still common and even ARMv6 support is also still supported by the GNU Compiler Collection. But as of Friday they dropped support for ARMv3 and older followed by dropping ARMv5 and ARMv5E.

The dropping of ARMv3 and older even includes finally eliminating the support for ARM2. The ARM2 target in GCC is finally no more.

This doesn't come as too much of a surprise though with pre-ARMv4T support being deprecated since GCC 6 and the ARMv5 support being deprecated since GCC 7 last year.

Linux fragmentation - The Sum of All Egos

Filed under
GNU
Linux

If Tom Clancy had been a technophile of the software kind, he'd have used this title instead of the familiar one for one of his iconic blockbuster thrillers. The thing is, Linux accounts for a tiny percentage of the overall desktop market share. The perennial 1% has been around roughly since 2005, and even if the actual share is higher than that, it's still a small and largely insignificant fraction. And yet, there are hundreds of Linux distributions populating this narrow, crowded arena. Why? Well, ego, of course.

One might say: open source. Ah, well, the open-source nature of Linux has been the chief excuse to the colorful abundance of replication and duplication of the Linux desktop world, while at the same time serving as the main catalyst to the expansion of Linux in the commercial space, which makes for a dubious cause. I believe the reason is different. Let me tell you what it is.

  • Mozilla Firefox 60.0.1 Released with Many Improvements, Disables WebVR on macOS

    Mozilla released on Wednesday the first point release to the Firefox 60.0 web browser, version 60.0.1, which brings several improvements and fixes some annoyances reported by users lately.

    One of the annoyances that Mozilla resolved in the Firefox 60.0.1 release, which started rolling out to Linux, Mac, and Windows platforms, is the displaying of "Sponsored content" on the New Tab page. Mozilla says that it will now immediately disappear when the user disables the "Sponsored Stories" option in Preferences.

    With the Firefox 60.0.1 release, the web browser now avoids overly long cycle collector pauses with certain add-ons, improves momentum scrolling on non-zoomable pages for touchscreen devices, and restores language translations of the Preferences panels when using a language pack.

  • Boxes now supports RDP connections

    Boxes has been the go-to option for easy virtual machine setups in GNOME for quite some time, but some people don’t know that our beloved application can also act as a remote viewer.

    The “Enter URL” option in the new machine assistant is how you get a new remote machine added to your collection. It supports addresses of Spice and VNC servers and oVirt and Libvirt brokers. You can also paste the URL of an operating system image (iso, img, qcow, etc…) and Boxes will download and boot it for you.

  • Dual Monitor: Fix Mouse Getting Stuck On Second Monitor In Gnome Shell With Ubuntu Dock Or Dash To Dock

    On my dual monitor setup, if I made any application fullscreen on the primary monitor (left-hand side screen - monitor "1" in the image above), the mouse cursor would get stuck on the secondary monitor (right-hand side screen) and I could only move it back to the primary monitor if I moved between monitors through the top part of the screen.

  • Dash to Panel Update Adds Intellihide, New Configuration Options

    Dash to Panel merges the GNOME Dash (aka Dock) and top bar into a unified, single panel that you can place on any edge of the screen:

    In the latest update, Dash to Panel v14, the task bar picks up a bunch of welcome improvements, including support for “intellihide” (aka auto-hide).

    This option (off by default) makes the panel slide out of view when an application window is maximised and/or touching it, and gracefully restored when there’s space for it.

    Although hidden you can access the panel at any time just by moving your mouse to the screen edge it’s hiding under.

    On April 22nd and 23rd, we attended a growing OSS event called FOSS North in Gothenburg – Sweden. According to foss-north.se, “FOSS-North is a free / open source conference covering both software and hardware from the technical perspective. Hosted in Gothenburg between Copenhagen, Oslo and Stockholm with an international airport, we provide a meeting place for the Nordic foss communities and will bring together great speakers with a great audience.” and that alone sounds like a lot of fun for us nerds!

    [...]

    FOSS-North hosted a bevy of different speeches during the 2-day period with 25 speakers, 2 of them from Jolla! We held our speech about the history of Jolla and the Sailfish community, continued by a piece of our roadmap for Sailfish X, Sailfish 3, and what is planned for the future. We ended the talk by a rather long Q&A from the audience. You can watch the whole talk below, and also access our slides that we used during the talk here.

  • Join us in Hamburg for the Hamburg Mini-DebConf!

    Thanks to Debian, I have the chance to be able to attend the Hamburg Mini-DebConf, taking place in Hamburg from May 16th to May 20th. We are hosted by Dock Europe in the amazing Viktoria Kaserne building.

  • MiniDebConf Hamburg - Thursday

    I missed my flight on Wednesday, and for a moment I thought I would have to cancel my attendance, but luckily I was able to buy a ticket for Thursday for a good price.

    I arrived at the venue just in time for a "stand-up" meeting, where people introduced themselves and shared what are they working on / planning to work on. That gave me a great feeling, having an idea of what other people are doing, and gave me motivation to work on my projects.

    The venue seems to be some kind of cooperative, with office space for different associations, there is also a small guest house (where I am sleeping), and a "kantina". The building seems very pretty, but is going through some renovations, so the scaffolding does not let you see it much. It also has a big outdoors area, which is always welcomed.

  • Blockchain Consolidation Phase Is Imminent, Hyperledger Chief Says

    Brian Behlendorf, a driving force behind the Apache web server and longtime supporter of open source software, now spends his time developing blockchain technology for the enterprise.

    As the executive director of the Hyperledger project, an open source blockchain initiative hosted by the Linux Foundation, Mr. Behlendorf is working to create enterprise-ready distributed ledger technologies and develop a community of corporate blockchain developers that will outlast a fevered investment climate.

    Blockchain is still nascent in the enterprise, but the conversation has evolved beyond basic technology questions to more involved discussions about scale, interoperability and governance, Mr. Behlendorf said.

  • 6 key data strategy considerations for your cloud-native transformation

    Many organizations are making the move to cloud-native platforms as their strategy for digital transformation. cloud-native allows companies to deliver fast-responding, user-friendly applications with greater agility. However, the architecture of the data in support of cloud-native transformation is often ignored in the hope that it will take care of itself. With data becoming the information currency of every organization, how do you avoid the data mistakes commonly made during this cloud transformation journey? What data questions should you ask when building cloud-native applications? How can you gain valuable insight from your data?

    The ensuing presentation includes six key considerations companies must have when they make this transition to cloud-native.

  • Making Kubernetes Easier with Cloud Foundry Platform

    Kubernetes is one of the biggest technology disruptors to hit the IT industry in a long time — maybe since Amazon EC2, now more than a decade old. It has helped turn containers from a convenient packaging method into the building blocks of modern application architectures, and has shifted the discussion in many circles from cloud computing to cloud-native computing.

    If that seems like a form of technological hair-splitting, it isn’t. Cloud-native technologies and architectures are the means by which more traditional businesses — like insurance, financial services or even heavy machinery — can transition from simply consuming cloud resources into operating like the cloud providers themselves. This is shifting the way they run their businesses, making them more agile, distributed and ready to tackle via software, whatever their businesses demand. As with most new technologies, however, it’s important to look at Kubernetes with some perspective.

  • Virtualized lab demonstration using a tweaked Labtainers running in a container

    Labtainers is quite interesting as it allows isolating a lab in several containers running in their own dedicated virtual network, which helps distributing a lab without needing to install anything locally.

    My tweak allows to run what I called the “master” container which contains the labtainers scripts, instead of having to install labtainers on a Linux host. This should help installation and distribution of labtainers, as well as deploying it on cloud platforms, some day soon. In the meantime Labtainer containers of the labs run with privileges so it’s advised to be careful, and running the whole of these containers in a VM may be safer. Maybe Labtainers will evolve in the future to integrate a containerization of its scripts. My patches are pending, but the upstream authors are currently focused on some other priorities.

Security and privacy: Do you know what's lurking on your system?

Filed under
Security

The first was the kernel. I ended up hand-crafting a kernel, removing anything I thought was unlikely we'd need, then restarting several times when I discovered that the system wouldn't boot because the things I thought I understood were more … esoteric than I'd realised. I'm not a kernel developer, and this was a salutary lesson in how skilled those folks are. At least, at the time I was doing it, there were less code and fewer options than there are today. On the other hand, I was having to hack back to a required state, and now there are more cut-down kernels and systems to start with than there were back then.

The other piece I left for last was pruning the installed operating system applications and associated utilities. Again, there are cut-down options that are easier to use now than then, but I also had some odd requirements—I believe that we needed Java, for instance, which has, or had …. well let's say a lot of dependencies. Most modern Linux distributions start off by installing lots of pieces so you can get started quickly without having to worry about trying to work out dependencies for every piece of external software you want to run.

  • virtual-keyboard: Add new virtual keyboard protocol
  • Purism Is Proposing A Virtual Keyboard Protocol For Wayland

    Purism's Dorota Czaplejewicz has been active within the Wayland community recently as they work on their Librem 5 phone Wayland compositor and Phosh shell for this software stack and iMX8 hardware they hope to begin shipping next year.

    On behalf of Purism, Dorota's latest Wayland work is proposing a new virtual keyboard protocol for Wayland. This allows for the emulation of keyboards by applications and complements the existing input-method protocol. The new virtual-keyboard protocol is based upon the Wayland keyboard specification but with support for seat bindings and dropping serials.

  • Introducing Calls

    Arguably the most critical functionality in a phone is the ability to make and receive calls through the Public Switched Telephone Network (PSTN), that is normal cellular calls using phone numbers. While at Purism we are eager to implement communication systems that enable much greater privacy and security than one can expect from PSTN calls, the PSTN is still the most ubiquitous network and for the time being we can’t very well go around selling a phone that isn’t able to make PSTN calls.⁰

    My task has been to develop a dialer and call handler for PSTN calls. Like all of our work on the Librem 5, this is intended to make use of existing code wherever possible and also target the GNOME platform which our PureOS defaults to. There is currently no GNOME PSTN dialer so we intend to contribute our program to the GNOME project.

  • Purism Introduces Its Telepathy-Using GTK3-Based Phone Dialer Plans

    Purism has formally introduced "Calls", its GTK3-based PSTN (Public Switched Telephone Network) phone dialing application that it hopes will be accepted into the upstream GNOME project. Purism plans to develop this phone dialer using GNOME's Telepathy framework but for now is using a simple oFono back-end.

    Calls is the new program Purism is developing to make and receive conventional telephone calls for supporting their default GNOME-based software stack being developed for the Purism 5 smartphone.

    While Telepathy is controversial among even GNOME developers, they are pursuing this framework for their phone call application as it will also support SIP calls and other features provided by the GNOME framework.

    The in-development Panfrost reverse-engineered, open-source driver for supporting ARM Mali T700 series graphics is now much more capable thanks to work carried out on their "half-way" Gallium3D driver in recent weeks.

    Alyssa Rosenzweig has provided an update on the Panfrost driver progress and their very early stage Gallium3D driver. Their recent code is quite a bit of progress considering where they were one month ago with just being able to render a cube.

  • CUDA 9.2 Released With GEMM Improvements

    We knew it was coming while today NVIDIA has rolled out the CUDA 9.2 stable release update.

    The CUDA 9.2 release includes speed-ups for launching CUDA kernels as well as faster performance for GEMM computational performance for half-precision and small N matrices. CUDA 9.2 also fixes a number of issues, including incorrect results with some GEMM calls on V100 Tensor Core GPUs and other BLAS problems.

  • Mesa 18.1 Released With Intel Shader Cache Default, OpenGL 3.1 ARB_compatibility

    First time Mesa release manager Dylan Baker has managed to release Mesa 18.1 on time as the Q2'2018 quarterly update to this OpenGL/Vulkan driver stack.

    While it feels like Mesa 18.0 was just recently released, it's already been a month and a half, which had arrived significantly late due to release delays. Fortunately, Mesa 18.1 is now available and hopefully allowing for a normal Mesa 18.2 release cycle for next quarter.

    Mesa 18.1 ships with the Intel OpenGL shader cache now being enabled by default, OpenGL 3.1 with ARB_compatibility context support for the prominent Gallium3D drivers, ARB_bindless_texture support for Nouveau NVC0 that is important for some newer Linux game ports like Dawn of War 3, EXT_semaphore support for RadeonSI, various other new OpenGL and Vulkan extensions being supported by Radeon and Intel, and other enhancements. See our Mesa 18.1 feature overview for a more thorough look at all of the changes that made it into this release.

Embracing and Extending Git, Push Notifications Harmful

  • Git Has A New Wire Protocol Yielding Much Greater Performance

    The Git Protocol Version 2 was announced today by Google as a major update to the distributed revision control system's wire protocol. Git protocol version 2 is much more efficient and yields significant performance benefits.

    The new Git wire protocol offers server-side filtering for references, easy extensibility for new features, and simplified client handling of the HTTP transport.

  • Introducing Git protocol version 2

    Today we announce Git protocol version 2, a major update of Git's wire protocol (how clones, fetches and pushes are communicated between clients and servers). This update removes one of the most inefficient parts of the Git protocol and fixes an extensibility bottleneck, unblocking the path to more wire protocol improvements in the future.

    The protocol version 2 spec can be found here.

    [...]

    We recently rolled out support for protocol version 2 at Google and have seen a performance improvement of 3x for no-op fetches of a single branch on repositories containing 500k references. Protocol v2 has also enabled a reduction of 8x of the overhead bytes (non-packfile) sent from googlesource.com servers. A majority of this improvement is due to filtering references advertised by the server to the refs the client has expressed interest in.

Hands-On with First Lubuntu 18.10 Build Featuring the LXQt Desktop by Default

Filed under
Reviews
Ubuntu

The Lubuntu development team promised to finally switch from LXDE (Lightweight X11 Desktop Environment) to the more modern and actively maintained LXQt (Lightweight Qt Desktop Environment), and the switch is now official.

Lubuntu developer Simon Quigley approached us earlier today to inform that the latest Lubuntu 18.10 daily build is quite usable as he and his team did a lot of work in the past week to accommodate the LXQt desktop environment by default instead of the LXDE desktop environment.

The main difference between LXDE and LXQt is that the former is written with the GTK+ 2 technologies, which will eventually be phased out in favor of the more advanced GTK+ 3, and the latter is built using the Qt framework. However, it doesn't look like there are any plans for LXDE to move to GTK+ 3.

Security Leftovers, Mostly 'Spectre' and 'Meltdown' Related

  • More Meltdown/Spectre Variants
  • Spectre V2 & Meltdown Linux Fixes Might Get Disabled For Atom N270 & Other In-Order CPUs
    There's a suggestion/proposal to disable the Spectre Variant Two and Meltdown mitigation by default with the Linux kernel for in-order CPUs. If you have an old netbook still in use or the other once popular devices powered by the Intel Atom N270 or other in-order processors, there may be some reprieve when upgrading kernels in the future to get the Spectre/Meltdown mitigation disabled by default since these CPUs aren't vulnerable to attack but having the mitigation in place can be costly performance-wise.

    Canonical released the first kernel security update for its Ubuntu 18.04 LTS (Bionic Beaver) operating system to fix a security issue that affects this release of Ubuntu and its derivatives. As you can imagine, the kernel security update patches the Ubuntu 18.04 LTS (Bionic Beaver) operating system against the recently disclosed Speculative Store Buffer Bypass (SSBB) side-channel vulnerability, also known as Spectre Variant 4 or CVE-2018-3639, which could let a local attacker expose sensitive information in vulnerable systems.
  • RHEL and CentOS Linux 7 Receive Mitigations for Spectre Variant 4 Vulnerability
    As promised earlier this week, Red Hat released software mitigations for all of its affected products against the recently disclosed Spectre Variant 4 security vulnerability that also affects its derivatives, including CentOS Linux. On May 21, 2018, security researchers from Google Project Zero and Microsoft Security Response Center have publicly disclosed two new variants of the industry-wide issue known as Spectre, variants 3a and 4. The latter, Spectre Variant 4, is identified as CVE-2018-3639 and appears to have an important security impact on any Linux-based operating system, including all of its Red Hat's products and its derivatives, such as CentOS Linux.
