GNOME’s New System Monitor Tool is Available to Try in Bionic

Filed under
GNOME

Cast you mind back to 2016 and you recall there were plans for a GNOME System Monitor redesign.

The aim: to make checking system resource usage a little more accessible, ideally with historical data thrown into the mix for some added context.

Two years on and the fruits of that redesigned effort are finally available to sample, albeit through a new app called (aptly enough) GNOME Usage.

GNOME: WebKit, Fleet Commander, Introducing deviced

GNOME
  • On Compiling WebKit (now twice as fast!)

    Are you tired of waiting for ages to build large C++ projects like WebKit? Slow headers are generally the problem. Your C++ source code file #includes a few headers, all those headers #include more, and those headers #include more, and more, and more, and since it’s C++ a bunch of these headers contain lots of complex templates to slow down things even more. Not fun.

  • Fleet Commander is looking for a GSoC student to help us take over the world

    Fleet Commander has seen quite a lot of progress recently, of which I should blog about soon. For those unaware, Fleet Commander is an effort to make GNOME great for IT administrators in large deployments, allowing them to deploy desktop and application configuration profiles across hundreds of machines with ease through a web administration UI based on Cockpit. It is mostly implemented in Python.

  • Introducing deviced

    Over the past couple of weeks I’ve been heads down working on a new tool along with Patrick Griffis. The purpose of this tool is to make it easier to integrate IDEs and other tooling with GNU-based gadgets like phones, tablets, infotainment, and IoT devices.

    Years ago I was working on a GNOME-based home router with davidz which sadly we never finished. One thing that was obvious to me in that moment of time was that I’m not doing another large scale project until I had better tooling. That is Builder’s genesis, and device integration is what will make it truly useful to myself and others who love playing with GNU-friendly gadgets.

GNOME: GitLab, LVFS and GStreamer

Filed under
GNOME
  • Weekend Website Experiment

    As you may know if you read this blog via Planet GNOME, the GNOME project is busy switching to GitLab for its code hosting and bug tracking. I like GitLab! It’s a large step up from Bugzilla, which was what GNOME used for the last 20 years. Compared to GitHub, GitLab is about equal, with a few nicer things and a few less nice things.

    The one thing that I miss from Bugzilla is a dashboard showing the overall status of the bugs for your project. I thought it would not be too hard to use the GitLab API to do some simple queries and plop them on a web page. So, last weekend I gave it a try. The final result is here. Click the button to log into GitLab, and you’ll be redirected back to the page where you’ll get the results of the queries.

  • LVFS will block old versions of fwupd for some firmware

    Although fwupd 0.8.0 was released over a year ago it seems people are still downloading firmware with older fwupd versions. 98% of the downloads from the LVFS are initiated from gnome-software, and 2% of people using the fwupdmgr command line or downloading the .cab file from the LVFS using a browser manually.

  • SRT in GStreamer

    Transmitting low delay, high quality video over the Internet is hard. The trade-off is normally between video quality and transmission delay (or latency). Internet video has up to now been segregated into two segments: video streaming and video calls. On the first side, streaming video has taken over the world of the video distribution using segmented streaming technologies such as HLS and DASH, allowing services like Netflix to flourish. On the second side, you have VoIP systems, which are generally targeted a relatively low bitrate using low latency technologies such as RTP and WebRTC, and they don't result in a broadcast grade result. SRT bridges that gap by allowing the transfer of broadcast grade video at low latencies.

GNOME Desktop/GTK: GNOME 3.27.90, ArcMPD, xdg-desktop-portal, Meson

  • GNOME 3.27.90 released
  • ArcMPD – An Arc-Based Translucent GTK Theme for Minimalists

    We haven’t written about any themes since 2018 began so I think it is about time that happened. That’s why I’m happy to let you in on another beautiful theme you might not have known yet – ArcMPD.

    ArcMPD is a fork of the fan favorite Arc GTK theme and its inspiration is even implied in its name. Unlike Arc GTK theme, however, it features a more transparent header, sidebar; and window control buttons reminiscent of Apple’s OS X.

  • Moving a portal

    Most of the portals in use are implemented by a module called xdg-desktop-portal, with backend implementations for Gtk+ and KDE. Many of the portals in it, such as the important file chooser portal relies on a lowlevel portal called the document portal. It is a combined dbus and fuse service that controls access to files with fine-grained per-application permissions.

  • Meson's dependency manager in action building GTK

    It is easy to see how this makes it easier for newcomers to participate. There are no longer pages upon pages of instructions on how to set up a build environment and so on. All that is required is to clone one Git repo and start building. The build system will take care of all the rest.

Solus 4 Is Coming Soon with Experimental Wayland Session for GNOME, Linux 4.15

Filed under
Linux
GNOME

Solus Project's Joshua Strobl posted today more details about the upcoming Solus 4 desktop operating system and some of the new features that will be integrated. These include a revamped Software Center with the latest Linux Driver Management for better hardware driver support, Hotspot support, Budgie 10.4.1, MATE 1.20, and an experimental Wayland session for the GNOME edition.

"Wayland will not be the default for Solus Budgie or Solus GNOME, however GNOME users will be able to install a separate session package if they wish to test and experiment with Wayland support," says Joshua Strobl. "During my testing, I have not found the quality of the GNOME + Wayland to be sufficient enough to be provided as a default experience for our users."

Better Late Than Never: GNOME 3.28 Beta Desktop Arrives for Valentine's Day

Filed under
GNOME

GNOME 3.28 is the next major update to the widely-used Linux desktop environment, which is now used by default in the popular Ubuntu operating system. It promises many new features, as well as a wide range of enhancements, especially under the hood as most of the components were ported to the Meson build system.

Most importantly, the beta was delayed because the GNOME 3.28 desktop environment is now using BuildStream project's build sandbox, which ensures a reliable build process regardless of the dependencies you might have installed on your GNU/Linux operating system.

  • Python for GNOME Mobile?

    As you may already know, Python is one of the hottest programming language out there, with thousand of job offerings, so makes sense, at least for me, to push this language as official one for GNOME Mobile applications.

    elementary OS is doing a good job on engagement new developers, while use Vala as its official language. For me, Vala is a good candidate for advanced/performance constrained Mobile applications.

  • Shelved Wallpapers

    GNOME 3.28 will release with another batch of new wallpapers that only a freaction of you will ever see. Apart from those I also made a few for different purposes that didn’t end up being used, but it would be a shame to keep shelved.

    So here’s a bit of isometric goodness I quite enjoy on my desktop, you might as well.

GNOME: GNOME 3.28, FOSDEM 2018 and More

  • Entering the “home stretch” for GNOME 3.28

    Earlier this week I´ve released GNOME Maps 3.27.90 (even though I just read an e-mail about the deadline for the release tarballs had been postponed for one week just after uploading the tarball).

    This weekend I (like some 8000 others) participated in an exciting FOSDEM with lots of interesting talks and the week before that I gave presentation of GNOME Maps, and in particular the public transit functionality for TrafikLab (the sort of “developer community” driven by the Swedish organization Samtrafiken AB, who coordinates and aggregates data from all public transit operators, both commercial/private and regional/public ones.

  • Bastian Ilsø Hougaard: Behind the GNOME Booth, FOSDEM 2018

    Saturday was spent selling lots and lots of socks. I choose this year not to go to any talks and instead hangout with fellow GNOMEies in the booth and have a chat with bypassing users. I’m accumulating many advertising arguments for buying socks including that it allows you to have feet on your feet and that you have an excuse to say “GNOME Socks!” as much as you want, once you own a pair. Wink Kat brought the awesome hoodies and then we had a big load of leftover t-shirts from GUADEC 2017 which we more or less sold (I think there’s still some 20 left in small). In the end we sold a 160 pairs of socks which is almost half the enormous stock of socks I purchased. When the evening came by and the booth had to close, we went to the GNOME Beer Event in La Bécasse, where I had my annual taste of Lambic Blanc, which is one of the few beers I really enjoy drinking.

  • Speaking at FOSDEM 2018 in Brussels, Belgium

    I think that we in the GNOME community can use data to make more informed decisions. For example, right now we’re fading out our Bugzilla instance and we don’t really have any way to measure how successful we are. In fact, we don’t even know what it would mean to be successful. But by looking at data we might get a better feeling of what we are interested in and what metric we need to refine to express better what we want to know. Then we can evaluate measures by looking at the development of the metrics over time. Spontaneously, I can think of these relatively simple questions: How much review do our patches get? How many stale wiki links do we have? How soon are security issues being dealt with? Do people contribute to the wiki, documentation, or translations before creating code? Where do people contribute when coding stalls?

  • Gnome without chrome-gnome-shell

    New laptop, has a touchscreen, can be folded into a tablet, I heard gnome-shell would be a good choice of desktop environment, and I managed to tweak it enough that I can reuse existing habits.

    I have a big problem, however, with how it encourages one to download random extensions off the internet and run them as part of the whole desktop environment. I have an even bigger problem with gnome-core having a hard dependency on chrome-gnome-shell, a plugin which cannot be disabled without root editing files in /etc, which exposes parts of my destktop environment to websites.

    Well, currently WikiToLearn runs on MediaWiki, which is a good model for dealing with an encyclopedia but, when you are trying to build a more structured content, it doesn’t fit.

    For the release 1.0 we have developed CourseEditor, which tries to make the unstructured content more structured, for example offering a drag-and-drop UI to manage a course structure.

  • On-Screen Keyboard Improvements, Thunderbolt UI Land In GNOME Shell

    Last minute work ahead of the imminent UI/feature freeze for GNOME 3.28 landed on Monday for the GNOME Shell.

    Most notable to the work that landed on Monday is the Thunderbolt policy provider and indicator. These are the UI/shell elements to Red Hat's Bolt project for dealing with secure handling of Thunderbolt peripherals when connected to Linux systems. The GNOME Shell bits interface with the Bolt daemon via the org.freedesktop.bolt D-Bus service. Great to see this UI work land in time for GNOME 3.28.

  • GTK+ 4.0 Gets More House Cleaning, Dropping Old Version References Saves ~7k L.O.C

    Yesterday I wrote about GTK4 dropping the Mir display back-end in favor of the Wayland back-end. Additionally, the "big GDK lock" was also stripped out. The latest is some additional cleaning to lighten the tool-kit code-base by about seven thousand lines of code.

    The latest significant cleanup is removing old GTK 2.x/3.x version references in the code and documentation. By dropping these old version annotations, GTK+ 4.0 saw nearly eight thousand lines of code removed but just over one thousand new insertions across more than 400 files.

  • MongoDB for WikiToLearn migration

    Today i want to talk about my experience with the WikiToLearn migration.

    The problem of every migration is getting your hands on the data in a way such that you can work on it.

    Starting from the mysql backend and trying to have everything into a versioned object storage (python eve is the one we are tring now) is not an option.

    The solution is to use a temporary database to keep the data, process the data in this temporary storage and afterwards uploading everything in the destination.

    After some tries we managed to have the pipeline that reads all the MediaWiki pages, parses the structure and uploads everything in eve, using mongodb as a temporary storage.

  • GTK4 Ejects The Mir Backend & Drops The Big GDK Lock

    After adding the Mir back-end for the GTK+ 3.16 cycle, GTK+ 4.0 is dropping this back-end for the Canonical-developed display server.

    The Mir back-end has been removed from the latest GTK+ code. This clears out about 6,500 lines of code from the tool-kit's codebase. The removal of the Mir back-end is coming since Mir has been focusing on Wayland protocol support to which GTK+ has more mature Wayland support than Mir. Since Mir's change of focus last year and the work the past number of months, the Wayland support on Mir has become more viable.

  • Ibus-Hangul and Compose key: the incredible journey of a simple patch

    Today I decided to tell how I reported a bug (then ended up fixing it) on a non-GIMP related project. Well I do regularly this kind of stuff, and this could have just been one more of these silent commits to a random project as I did many times in my life. But since I decided recently to post more articles, well… I may as well tell a story as one-time contributor (as opposed to “regular contributor”) for once!

    Also I think the whole process of reporting a bug on projects you don’t know at all — worse! A whole stack of software you don’t know much! — is quite interesting for people wondering how they should report bugs happening to them.

  • On GNOME 3.27.90, time management, and a goodbye

    This is a first version that can be polished further but it works quite well. This is the original C/C++/SDL2 code with a few tweaks, cross-compiled to WebAssembly (and an alternate version in asm.js) with emscripten. Nothing brand new I know, but things are getting smoother, and WebAssembly is definitely a performance boost. I like distributed and autonomous tools, so I'm generally not inclined to web-based solutions. In this case however, this is a local version of the game. There's no server side. Savegames are in your browser local storage. Even importing D-Mods (game add-ons) is performed purely locally in the in-memory virtual FS with a custom .tar.bz2 extractor cross-compiled to WebAssembly.

  • Why bootstrap?
    Over the next few quarters, I'm going to focus my attention on Mozilla's experimentation platform. One of the first questions we need to answer is how we're going to calculate and report the necessary measures of variance. Any experimentation platform needs to be able to compare metrics between two groups. For example, say we're looking at retention for a control and experiment group. Control shows a retention of 88.45% and experiment shows a retention of 90.11%. Did the experimental treatment cause a real increase in retention or did the experiment branch just get lucky when we assigned users? We need to calculate some measure of variance to be able to decide. The two most common methods to do this calculation are the frequentist's two-sample t-test or some form of the bootstrap. In ye olden days, we'd be forced to use the two-sample t-test. The bootstrap requires a lot of compute power that just wasn't available until recently. As you can imagine, the bootstrap is all the rage in the Data Science world. Of course it is. We get to replace statistics with raw compute power! That's the dream!
