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.

Ubuntu: Data Collection, a Decade at Canonical, Xubuntu 18.04 Community Wallpaper Contest

Filed under
Ubuntu
  • Canonical wants Ubuntu to collect your personal data

    This has gone down like a bucket of cold sick with Linux users. After all, this is the sort of thing that Microsoft does and is precisely the sort of thing that they hate about Windows 10.

  • 10 Amazing Years of Ubuntu and Canonical

    10 years ago today, I joined Canonical, on the very earliest version of the Ubuntu Server Team!

    And in the decade since, I've had the tremendous privilege to work with so many amazing people, and the opportunity to contribute so much open source software to the Ubuntu ecosystem.

    We’re on our way to the 18.04 LTS release and it’s time for another community wallpaper contest!

KDE: Qt, Cutelyst, Spectacle, Kirigami

Filed under
KDE
  • SFXR Qt noise buffer

    I was working on adding sounds to Pixel Wheels rescue helicopter, so I started SFXR Qt and after a few experiments I came up with a decent sound. Unfortunately it did not sound that good in the game. It was much more dull than in the app. Listening again to the sound in SFXR Qt I realized there were subtle variations between each plays, which made the sound more interesting.

  • Qt in Visual Studio: Improving Performance

    In the last post, we discussed a new approach to design time and build time integration of external tools in Visual Studio using MSBuild rules and targets. This will be included in the upcoming release of version 2.2 of the Qt VS Tools. In this post, we will discuss the performance improvements that are also included in this new version.

  • Cutelyst on TechEmpower benchmarks round 15

    Since this round took a long time and was scheduled to be release many times last year I decided not to update Cutelyst to avoid not having the chance to fix any issues and have broken results. Cutelyst 1.9.0 and Qt 5.9 were used, both had some performance improvements compared to round 14, and thus you can see better results on this round compared to 14, most notably the JSON tests went from 480K request/second to 611K req/s, also due this old Cutelyst release jemalloc was again not used due a bug we had in CMake files that didn’t link against it.

  • Usability & Productivity highlight: Spectacle

    Over the past few weeks, we’ve done a lot of Usability & Productivity work for Spectacle, KDE’s screenshot tool. I’d like to share the progress! But first, a screenshot. Here’s how spectacle looks now:

  • This week in Discover (and Kirigami!), part 6

    This is going to be a double-header: today we’re discussing Discover as well as Kirigami–KDE’s UI framework that facilitates writing convergent apps that look and feel good on both the desktop and a mobile device.

    …At least that’s the idea. The truth is, KDE users have voiced a lot of criticism for how well this works out in practice. An especially common complaint is that the desktop user experience gets short shrift, and Kirigami apps feel like big phone apps.

  • LibreOffice 6.0.1 Available To Install In Ubuntu/Linux Mint

    LibreOffice is the power-packed free, libre and open source personal productivity suite for Windows, Macintosh and GNU/Linux, that gives you six feature-rich applications for all your document production and data processing needs: Writer: the word processor, Calc: the spreadsheet application, Impress: the presentation engine, Draw: our drawing and flowcharting application, Base: our database and database frontend, and Math: for editing mathematics.

  • LibreOffice 6.0 scored close to 1 million downloads in just 14 days

    The LibreOffice 6.0 release at the end of January was met by enthusiasm from tech bloggers and open-source enthusiasts alike.

    And that enthusiasm translated into some very healthy download numbers.

  • HiFive, LibreOffice, Meltdown and Spectre and more

    We would like to congratulate the hard working folks behind the LibreOffice 6.0 application suite. Officially released on January 31, the site has counted almost 1 million downloads. An amazing accomplishment.

Plasma – The road to perfection is paved with bugs

Filed under
KDE

There you go. Now, before you say “But Windows or Gnome also …” Wait. Stop. The purpose of this list is not to seek solace in failures or incomplete/imperfect implementations of desktop environment solutions that may exist out there. The purpose is to express my view, as an individual user, of the big and little things that do not seem to work well in Plasma. After all, the desktop is there to allow people to enjoy themselves, to have fun, to be productive, and whatnot. And every little papercut or inconsistency is detrimental to the experience.

It would be a nice exercise to actually do the same thing with … other desktop environments. I believe that Plasma probably has the fewest issues, as odd as it may sound after you’ve just consumed this long j’accuse list. But it is still not perfect, it’s still not good enough to everyday use, and there are many things that need to be improved. Then again, no one said creating a splendid desktop environment was going to be easy or boring, right. Take care, and perhaps in your comments, you will come up with a few more niggles that I missed. Let’s hear your thoughts. Spill them out.

diff -u: Automated Bug Reporting

Filed under
Linux

A variety of automated bug-hunters are roaming around reporting bugs. One of them is Syzbot, an open-source tool specifically designed to find bugs in Linux and report them. Dmitry Vyukov recently sent in a hand-crafted email asking for help from the community to make Syzbot even more effective.

The main problems were how to track bugs after Syzbot had reported them and how to tell when a patch went into the kernel to address a given bug.

It turned out that Andrey Ryabinin and Linus Torvalds got together to collaborate on an easy solution for Dmitry's problem: Syzbot should include a unique identifier in its own email address. The idea is that anything after a "+" in an email address is completely ignored. So zbrown@gmail.com is exactly the same as zbrown+stoptrump@gmail.com. Andrey and Linus suggested that Syzbot use this technique to include a hash value associated with each bug report. Then, Linux developers would include that email address in the "Reported-By" portion of their patch submissions as part of the normal developer process.

Real-time Linux based automation controller supports up to 16 I/O modules

Filed under
Linux

Opto 22 announced its first Linux-based automation controller: a rugged “Groov EPIC” system that runs real-time Linux on a quad-core ARM SoC, and supports process and machine control, SCADA/RTU, and industrial IoT edge gateway applications.

Increasingly, industrial equipment manufacturers must not only compete on features, but also meet their clients’ need to attract the best developers. That often means shifting from proprietary RTOS or Windows based solutions to Linux. The latest to make the switch is Opto 22, whose announcement suggests the Groov EPIC controller represents a major new product direction compared to its previous Groov products.

The npm Bug

  • ​Show-stopping bug appears in npm Node.js package manager
    Are you a developer who uses npm as the package manager for your JavaScript or Node.js code? If so, do not -- I repeat do not -- upgrade to npm 5.7.0. Nothing good can come of it. As one user reported, "This destroyed 3 production servers after a single deploy!" So, what happened here? According to the npm GitHub bug report, "By running sudo npm under a non-root user (root users do not have the same effect), filesystem permissions are being heavily modified. For example, if I run sudo npm --help or sudo npm update -g, both commands cause my filesystem to change ownership of directories such as /etc, /usr, /boot, and other directories needed for running the system. It appears that the ownership is recursively changed to the user currently running npm."
  • Botched npm Update Crashes Linux Systems, Forces Users to Reinstall
    A bug in npm (Node Package Manager), the most widely used JavaScript package manager, will change ownership of crucial Linux system folders, such as /etc, /usr, /boot. Changing ownership of these files either crashes the system, various local apps, or prevents the system from booting, according to reports from users who installed npm v5.7.0. —the buggy npm update.
