What am I doing with Tracker?

Filed under
GNOME

Some years ago I was asked to come up with some support for sandboxed apps wrt indexed data. This drummed up into Tracker 2.0 and domain ontologies, allowing those sandboxed apps to keep their own private data and collection of Tracker services to populate it.

Fast forward to today and… this is still largely unused, Tracker-using flatpak applications still whitelist org.freedesktop.Tracker, and are thus allowed to read and change content there. Despite I’ve been told it’s been mostly lack of time… I cannot blame them, domain ontologies offer the perfect isolation at the cost of the perfect duplication. It may do the job, but is far from optimal.

So I got asked again “we have a credible story for sandboxed tracker?”. One way or another, seems we don’t, back to the drawing board.

Mutter 3.33.4

Filed under
GNOME

About mutter
============

Mutter is a window and compositing manager that displays and manages
your desktop via OpenGL. Mutter combines a sophisticated display
engine using the Clutter toolkit with solid window-management logic
inherited from the Metacity window manager.

While Mutter can be used stand-alone, it is primarily intended to be
used as the display core of a larger system such as GNOME Shell. For
this reason, Mutter is very extensible via plugins, which are used
both to add fancy visual effects and to rework the window management
behaviors to meet the needs of the environment.

GNOME

I have recently spent some time on Pango again, in preparation for the Westcoast hackfest. Behdad is here, and we’ve made great progress on the first day.

My last Pango update laid out our plans for Pango. Today I’ll summarize the major changes that will be in the next Pango release, 1.44.

Ubuntu/Fedora GNOME Feud and GNOME's Sriram Ramkrishna

  • Fedora, GNOME Software, and snap

    A question about the future of package distribution is at the heart of a disagreement about the snap plugin for the GNOME Software application in Fedora. In a Fedora devel mailing list thread, Richard Hughes raised multiple issues about the plugin and the direction that he sees Canonical taking with snaps for Ubuntu. He plans to remove support for the plugin for GNOME Software in Fedora 31.

    There are currently two major players for cross-distribution application bundles these days: snaps, which were developed by Canonical for Ubuntu and the Snap Store, and Flatpak, which was developed by Alexander Larsson of Red Hat as part of freedesktop.org. Both systems are available for multiple Linux distributions. They are meant to give an "app-like" experience, where users simply install an application, which comes with any dependencies it has that are not provided by the snap or Flatpak runtime.

    The GNOME Software application has a snap plugin that, when enabled, supports the distribution, installation, and management of snaps. The Fedora project currently provides the snap plugin as a package in Fedora 30, though it is not installed by default. Hughes is the Fedora maintainer for the plugin; he announced his intention to disable the plugin since, he says, he was told that Canonical was not going to be installing GNOME Software in the next Ubuntu Long Term Support (LTS) release.

  • Molly de Blanc: Meet Sriram Ramkrishna

    Sriram Ramkrishna, frequently known as Sri, is perhaps GNOME’s oldest contributor. He’s been around the community for almost as long as it’s been around!

    [...]

    But more than that, GNOME was a project that if you think about it was audacious in its purpose. Building a desktop in 1997 around an operating system that was primitive in terms of user experience, tooling, and experience. I wanted to be part of that.

GNOME: GSOC, GNOME Foundation, GLib

  • Gaurav Agrawal: GSOC Progress by Mid July

    July Marked the beginning of II GSOC coding month. This month our goal is to make the diff bar model as accurate and intuitive as possible.

    One of the biggest thing which I learnt so far is how to contribute on upstream repositories on which our project depends.

    In our case this was with Libgit2, we discovered a bug in Libgit2 while doing our project, and Albfan made this a perfect example to show me how to contribute on upstream, how to raise bugs and how to do discussions for getting it solved.

  • Andrei Lisita: Getting closer

    Since my last blog post I have been on a short vacation but I have also managed to make some progress on my GSoC project again with guidance from my mentor.

    [...]

    Every savestate also has a creation date which is displayed in the menu, but that’s certainly not as eye-catching as the screenshots.

    There are still many missing features and things that need improving (such as the date formatting) but with every commit I feel that I am getting closer to the finished project.

  • KDE Plasma5 for Slackware, introducing Qt 5.13 in the July’19 update

    Now that all major components of the KDE software stack have fresh new releases, I bundled them for Slackware-current and voila: KDE-5_19.07.

    I have uploaded KDE-5_19.07 to my ‘ktown‘ repository. As always, these packages are meant to be installed on a full installation of Slackware-current which has had its KDE4 removed first. These packages will not work on Slackware 14.2.

  • The new userbase wiki

    When you find a kool feature in KDE software, you can write a small tutorial or just a small paragraph about it and the KDE Userbase Wiki is the right place to publish it. You don’t need to know how to code, have perfect English or know how MediaWiki’s formatting work, to contribute. We also need translators.

GNOME: Summer of Code with Pitivi, GLib 2.61.2 and GNOME's Mutter Picks Up Another Optimization

    In the first phase of my project, I worked on redesigning Pitivi’s “Effect Library” to allow users to easily find, organise and utilize their desired effects.

  • g_test_summary and g_get_console_charset in GLib 2.61.2

    Another short post about new APIs, this time from the upcoming 2.61.2 release. This time it’s two unrelated new APIs, which I’m covering together because they’re fairly short.

    g_test_summary() is a new API along the same lines as the existing g_test_bug() function. It’s to be called from within a unit test to provide a summary of the test to the test harness. In contrast, g_test_bug() provides a bug reference for the unit test. In this fashion, the two can be used to provide documentation within the test code of what the test is testing, how it goes about testing it, and which bug it’s checking for regressions in. The summary passed to g_test_summary() might be printed out as a comment in the test logs.

  • GNOME's Mutter Picks Up Another Optimization For Helping DisplayLink-Type Hardware

    Collabora's Pekka Paalanen landed another optimization this week into GNOME's Mutter for further enhancing the performance of using DisplayLink hardware and similar secondary GPUs under this Linux desktop.

    Over the past few cycles we've seen a lot of improvements made for bettering the performance of DisplayLink USB graphics connected displays under the GNOME desktop environment. While the experience has already improved a lot, for GNOME 3.34 due out in September will be more optimizations.

I have been involved GNOME for a long time. My first commits to GTK are from sometime around 2002. GTK is where I spend most of my development and project maintenance time. But I’ve been involved in many other parts of GNOME at one point or another, from GLib to GNOME Software.
Apart from writing code and fixing bugs, I am a member of the release team, and do a few of the GNOME releases every cycle. In recent years, I’ve often done the .0 stable releases.

GNOME Software in Fedora will no longer support snapd

In my slightly infamous email to fedora-devel I stated that I would turn off the snapd support in the gnome-software package for Fedora 31. A lot of people agreed with the technical reasons, but failed to understand the bigger picture and asked me to explain myself.

I wanted to tell a little, fictional, story:

In 2012 the ISO institute started working on a cross-vendor petrol reference vehicle to reduce the amount of R&D different companies had to do to build and sell a modern, and safe, saloon car.

Industrial PC with 6th or 7th Gen Intel CPUs has four PCIe slots for Nvidia graphics

Axiomtek’s “IPC974-519-FL” industrial PC for AI edge applications runs on Xeon E3 or 6th or 7th Gen Core CPUs and offers 4x PCIe/PCI slots for up to 300W Nvidia graphics plus 2x SATA, 2x GbE, and modular I/O expansion. Axiomtek announced the latest member in its line of IPC (industrial PC) computers with full-sized PCIe/PCI expansion slots. The new IPC974-519-FL computer is very similar to the IPC962-511-FL we reported on last February, which similarly supports Intel Xeon E3 or 6th Gen (Skylake) or 7th Gen (Kaby Lake) Core CPUs. However, the new model has four PCIe/PCI expansion slots instead of two. Read more

Red Hat Enterprise Linux 6 and CentOS 6 Receive Important Kernel Security Update

Marked by the Red Hat Product Security team as having a security impact of "Important," the new Linux kernel security update is here to patch a memory corruption (CVE-2018-9568) that occurred due to incorrect socket cloning and a NULL pointer dereference (CVE-2019-11810) discovered in drivers/scsi/megaraid/megaraid_sas_base.c, which could lead to a denial of service. Also fixed in this update are two bugs affecting the performance of the Linux kernel on Red Hat Enterprise Linux 6 and CentOS Linux 6 systems, namely a fragmented packets timing out issue and the backport TCP follow-up for small buffers. These two bugs can be corrected if you install the new kernel versions for your operating system. Read more
