KDE: KDevelop 5.3.3 Released, Latte Dock Update and Release of Kaidan 0.4.1

Filed under
KDE

  • KDevelop 5.3.3 released

    We today provide a stabilization and bugfix release with version 5.3.3. This is a bugfix-only release, which introduces no new features and as such is a safe and recommended update for everyone currently using a previous version of KDevelop 5.3.

    You can find a Linux AppImage as well as the source code archives on our download page. Windows installers are no longer offered, we are looking for someone interested to take care of that.

  • Latte, Documentation and Reports...

    First Latte beta release for v0.9.0 is getting ready and I am really happy about it Smile . But today instead of talking for the beta release I am going to focus at two last minute "arrivals" for v0.9; that is Layouts Reports and Documentation. If you want to read first the previous article you can do so at Latte and "Flexible" settings...

  • Kaidan 0.4.1 released!

    After some problems were encountered in Kaidan 0.4.1, we tried to fix the most urgent bugs.

Krita 4.2.3 Released

Filed under
KDE

Today we’re releasing Krita 4.2.3. This is mostly a bug fix release, but has one new feature: it is now possible to rotate the canvas with a two-finger touch gesture. This feature was implemented by Sharaf Zaman for his 2019 Google Summer of Code work of porting Krita to Android. The feature also works on other platforms, of course.

The most important bug fix is a workaround for Windows installations with broken, outdated or insufficient graphics drivers. The core of the issue is that our development platform, Qt, in its current version needs a working OpenGL or Direct3D installation as soon as there is a single component in the application that uses QML, a technology for creating user interfaces. We have managed to work around this issue and especially users of Windows 7 systems that have become a bit messy should be able to run Krita again.

Q4OS 3.8 Centaurus, stable

Filed under
OS
KDE

We are proud to announce the immediate availability of the brand new stable Q4OS 3.8 version, codenamed 'Centaurus'. This is a long-term support LTS release, to be supported for at least five years with security patches and software updates.

The primary Q4OS aim is stability. As we want to provide as stable as possible operating system for companies as well as for individuals, once installed and configured, Q4OS will work reliably in a long standing way, getting security fixes and updates. Adopting a new feature into the core system could be committed in a highly exceptional cases only. We treat such possible cases as best as possible, doing testing and investigating consequences carefully before such a change.

Q4OS Centaurus is based on Debian Buster 10 and Plasma 5.14, optionally Trinity 14.0.6, desktop environment, and it's available for 64bit and 32bit/i686pae computers, as well as for older i386 systems without PAE extension. We are working hard to bring it for ARM devices too.

  • 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.

KDE Itinerary - Vector Graphic Barcodes

Filed under
KDE

I have previously written about why we are interested in barcodes for the KItinerary extractor. This time it’s more about the how, specifically how we find and decode vector graphic barcodes in PDF files, something KItinerary wasn’t able to do until very recently.

While PDF is a vector graphics format, most barcodes we encounter in there are actually stored as images. Technically this might not be the cleanest or most efficient way, but it makes KItinerary’s life very easy: We just iterate over all images found in the PDF, and feed them into the barcode decoder.

It’s of course a bit more complicated to make this as efficient as possible, but conceptually you could script this with Poppler’s pdfimages command line tool and ZXing with just a few lines of code.

Kdenlive 19.04.3 is out

Filed under
KDE

While the team is out for a much deserved summer break the last minor release post-refactoring is out with another huge amount of fixes. The highlights include fixing compositing and speed effect regressions, thumbnail display issues of clips in the timeline and many Windows fixes. With this release we finished polishing the rough edges and now we can focus on adding new features while fixing other small details left. As usual you can get the latest AppImage from our download page.

Speaking of that, the next major release is less than a month away and it already has some cool new features implemented like changing the speed of a clip by ctrl + resize and pressing shift and hover over a thumb of a clip in the Project Bin to preview it. We’ve also bumped the Qt version to 5.12.4 and updated to the latest MLT. You can grab it from here to test it. Also planned is finishing the 3 point editing workflow and improvements to the speed effect. Stay tuned for more info soon.

KDE Applications 19.04 Reaches End of Life, KDE Apps 19.08 Arrives on August 15

Filed under
KDE

Launched on April 18th, 2019, the KDE Applications 19.04 open-source software suite series received a total of three maintenance updates, the last one being released today as KDE Applications 19.04.3, which fixes some remaining issues but also marks the end of life of KDE Applications 19.04.

KDE Applications 19.04.3 brings numerous changes across various of the included applications, but the most important changes are the fact that the Konqueror and Kontact apps no longer crash on exit when QtWebEngine 5.13 is used and the Python importer in the Umbrello UML app now supports parameters with default arguments.

Security: Linux 5.2 Dissection, New Patches, New ZDNet (CBS) FUD and Kali NetHunter App Store

  • Kees Cook: security things in Linux v5.2

    Gustavo A. R. Silva is nearly done with marking (and fixing) all the implicit fall-through cases in the kernel. Based on the pull request from Gustavo, it looks very much like v5.3 will see -Wimplicit-fallthrough added to the global build flags and then this class of bug should stay extinct in the kernel. That’s it for now; let me know if you think I should add anything here. We’re almost to -rc1 for v5.3!

  • Security updates for Wednesday

    Security updates have been issued by Debian (libreoffice), Red Hat (thunderbird), SUSE (ardana and crowbar, firefox, libgcrypt, and xrdp), and Ubuntu (nss, squid3, and wavpack).

  • Malicious Python Libraries Discovered on PyPI, Offensive Security Launches the Kali NetHunter App Store, IBM Livestreaming a Panel with Original Apollo 11 Technicians Today, Azul Systems Announces OpenJSSE and Krita 4.2.3 Released

    Offensive Security, the creators of open-source Kali Linux, has launched the Kali NetHunter App Store, "a new one stop shop for security relevant Android applications. Designed as an alternative to the Google Play store for Android devices, the NetHunter store is an installable catalogue of Android apps for pentesting and forensics". The press release also notes that the NetHunter store is a slightly modified version of F-Droid: "While F-Droid installs its clients with telemetry disabled and asks for consent before submitting crash reports, the NetHunter store goes a step further by removing the entire code to ensure that privacy cannot be accidentally compromised". See the Kali.org blog post for more details.

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.

Mozilla: Android, VR and Rust

  • Recent fixes to reduce backlog on Android phones

    Last week it seemed that all our limited resource machines were perpetually backlogged. I wrote yesterday to provide insight into what we run and some of our limitations. This post will be discussing the Android phones backlog last week specifically. The Android phones are hosted at Bitbar and we split them into pools (battery testing, unit testing, perf testing) with perf testing being the majority of the devices.

  • Q&A: Igniting imaginations and putting VR in the hands of students with Kai Frazier

    When you were in school, you may have taken a trip to a museum or a local park, but you probably never got to see an active volcano or watch great whites hunt. As Virtual Reality grows, this could be the way your kids will learn — using headsets the way we use computers. When you were in school, you may have gone on a trip to the museum, but you probably never stood next to an erupting volcano, watching molten lava pouring down its sides. As Virtual Reality (VR) grows, learning by going into the educational experience could be the way children will learn — using VR headsets the way we use computers. This kind of technology holds huge potential in shaping young minds, but like with most technology, not all public schools get the same access. For those who come from underserved communities, the high costs to technology could widen an already existing gap in learning, and future incomes.

Python Programming Leftovers

  • Generate a List of Random Integers in Python

    This tutorial explains several ways to generate random numbers list in Python. Here, we’ll mainly use three Python random number generation functions. These are random.randint(), random.randrange(), and random.sample(). You can find full details of these methods here: Generate random numbers in Python. All these functions are part of the Random module. It employs a fast pseudorandom number generator which uses the Mersenne Twister algorithm. However today, we’ll focus on producing a list of non-repeating integers only. Go through the below bullets to continue.

  • Gradient Boosting Classifiers in Python with Scikit-Learn

    Gradient boosting classifiers are a group of machine learning algorithms that combine many weak learning models together to create a strong predictive model. Decision trees are usually used when doing gradient boosting. Gradient boosting models are becoming popular because of their effectiveness at classifying complex datasets, and have recently been used to win many Kaggle data science competitions. The Python machine learning library, Scikit-Learn, supports different implementations of gradient boosting classifiers, including XGBoost.

  • Create a Flask Application With Google Login

    You’ve probably seen the option for Google Login on various websites. Some sites also have more options like Facebook Login or GitHub Login. All these options allow users to utilize existing accounts to use a new service. In this article, you’ll work through the creation of a Flask web application. Your application will allow a user to log in using their Google identity instead of creating a new account. There are tons of benefits with this method of user management. It’s going to be safer and simpler than managing the traditional username and password combinations. This article will be more straightforward if you already understand the basics of Python. It would also help to know a bit about web frameworks and HTTP requests, but that’s not strictly necessary.
