KDE
  • Yahoo hit QupZilla.

    As most you already know as an XFCE environment installation comes with QupZilla web browser.
    The QupZilla web browser is a lightweight multiplatform web browser written in Qt Framework and using its web rendering engine QtWebEngine.
    If you using Fedora 28 the you can get the Falkon web browser.
    The wikipedia tell us about Falkon browser "(formerly QupZilla[3]) is a free and open-source web browser, intended for general users. Falkon is licensed under GPLv3."
    The Falkon browser working well with Yahoo.

  • Building KDE Connect

    After I shared the link to the KDE Connect Development Telegram group almost 20 people joined within 24 hours. I certainly did not expect such a interest in KDE Connect. When I joined the project about a year ago the hardest part for me was setting up a proper development workflow, meaning configuring, building, installing and debugging the application and interacting with git and Phabricator. To ease your start in KDE Connect development I would like to give you the guide I wish I had back then.

    I will show you how to fetch the project, build, run and debug it using KDevelop. It’s an IDE by the KDE Community designed with KDE projects in mind. In theory you can use any IDE you like, if you figure out how to configure it properly.

  • KDE Connect – New stuff I

    In my first post about KDE Connect I told you about the album cover art on Android. Thanks to Matthijs it now also works when the cover art is a local file, for example when you are using VLC. It already worked when the cover art was a remote URL, for example with Spotify. The cover art is now also shown in the media control notification and added to the Android media session.

  • KDAB at Embedded World 2018

    Embedded World, the leading exhibition for the international embedded community, just had its 16th edition and is still growing, with more than 1000 exhibitors and over 32,000 visitors from 78 countries in 2018.

    Software was more central to the exhibition than ever before, so it’s no wonder this is KDAB’s 8th year in a row exhibiting.

  • Qbs 1.11 Released As The Qt Build Tool Successor To QMake

    In addition to the Qt Creator 4.6 IDE being released today, The Qt Company also released the Qbs 1.11 build system.

  • Qbs 1.11 released

    We are happy to announce version 1.11.0 of the Qbs build tool.

  • Qt Creator 4.6.0 released

    We are happy to announce the release of Qt Creator 4.6.0!

  • Qt Creator 4.6 Released With Upgraded C++ Support, Navigation Improvements

    The Qt Company has released Qt Creator 4.6, the latest version of their Qt/C++ focused integrated development environment.

    Qt Creator 4.6 upgrades the C++ support thanks to moving its Clang-based code model from Clang 3.9 to the newer Clang 5.0, which in turn provides more C++17 features and other enhancements. Qt Creator 4.6 also has integration of Clang-Tidy and Clazy warnings into the editor's diagnostics messages, highlighting improvements, and other enhancements.

  • C++ Modernization Brochure

    New releases of the C++ language maintain incredibly strong backwards compatibility, making it easy to keep older C++ code working properly as standards march forward. C++11, C++14, and C++17 have transformed the C++ language in ways that make it as programmer-friendly as more recent languages but with many essential benefits that continue to make it the best choice for the most demanding software-engineering projects.

    Modernizing your C++ may be the best way to both improve your team’s efficiency as well as future-proof your software investment. KDAB has broad, deep experience delivering cost-effective, long-term, pragmatic solutions that modernize existing C++ codebases without losing functionality during the process.

Krita – Ars longa, vita brevis?

Filed under
KDE

My first encounter with Krita has been interesting so far. On one hand, without any tutorial and only my prior knowledge of GIMP, I was able to do about 80% of the stuff that I wanted, and that’s pretty good. Add to that some extra features that GIMP does not have, and you have yourself a reasonable IMP.

But then, on the other hand, there were a lot of frustrations – and that’s even before I got a chance to sit down for a few hours and paint. Macros didn’t work as well as they should, GIMC is missing, and some of the effects and options are clunky. Maybe all of it comes down to habit, but I doubt it. I have a fairly good natural affinity toward software, and if it’s not intuitive, it means it’s not designed right. Krita has some decent features, but then it also has some (let’s call them GIMP-like) quirks that simply make no sense from the workflow perspective. The UI show work with you, not against you.

All in all, Krita is better than what I’d expected. Things also become slightly more complicated when you take into account Karbon, which is another KDE application and part of the Calligra suite, but it also does vector graphics, and perhaps competes or complements Krita. The duality between GIMP and Krita is also intriguing, but also an indication of forking and wasted energy, because there’s 70% common base in both programs that could have been invested making dope effects, like, I don’t know, a comic strip speech bubble, rather than replicating what’s already there. In a way.

Bottom line, I like Krita, and I will explore it some more, trying to master its interface and options, and perhaps even render some original art without shouting at the computer. For me, GIMP is a no-go in this regard, so this will be an interesting comparison experiment. Lastly, I’d like to see more effects, GIMC seamlessly integrated, and the macros must work. Well, there you go.

Plasma 5.12 - 28 Days Later

Filed under
KDE

Plasma 5.12.2 brings in a lot of real, noticeable improvements, and it's a delight to see a living, breathing desktop environment that is pushing hard to become better and more accessible to its users. That said, the expectation of overnight miracles should be avoided, otherwise, you will, a bit like me, wrestle (naked) with frustration. Plasma is on the right course, but it will take a while before it becomes the dreamland bucket of code we want it to be. But the sooner the better, because competition, history and relevance won't wait.

I know it's easier to fix small things - but the ones that need attention and focus are the big ones. The things that ordinary people will see first, no matter how seemingly trivial they might seem. This is even more important for new users, because those already dabbling in Plasma will have made custom configurations that already cater to their needs and work around the system inefficiencies and problems. But then, if it were so easy, I'd have nothing to write and complain. I'm happy. Catch you in the sequel.

KAuth support in KDE Partition Manager

Filed under
KDE

Last November I reported that running KDE Partition Manager as non-root user is slowly shaping up. Instead of running the whole application as root, KAuth lets us run GUI parts as unprivileged user and some non-GUI helper running as root.

After another 4 months of development, KAuth support is mostly done. There are still a few things that need to be finished, some cleaning up, fixing bugs but major refactoring is complete. Unlike other KDE Applications, KDE Partition Manager uses root for almost any operation, so the way it uses KAuth is quite different from e.g. Kate where the only task the helper has to do is to copy the file to its destination. KDE Partition Manager might need to execute a lot of different commands to do some task (e.g. move/resize partition) and we don’t want user to authenticate 20 times during partitioning operation.

  • Certifiably Qt

    Expanding your team’s software development capacity is something that most managers will encounter at some point in their careers. There are several ways to do this – three of the most common options are hiring new employees, using a service company, or incorporating onsite contractors. Regardless of which route you choose to go, software certifications are an effective tool to help you identify the right resources. Qt certifications are a case in point.

  • Statistics, Google Code-in, Gitlab, Bugzilla
  • Collabora & GStreamer 1.14

    After a particularly long cycle of over 10 months, the GStreamer community had accumulated a lot of improvements that are now widely available in the 1.14 release. The release notes contain a good explanation of everything the community has produced, but I'd like to highlight some of the contributions from Collabora's engineers that we're particularly proud of.

  • Low-latency audio on Windows with GStreamer

    Digital audio is so ubiquitous that we rarely stop to think or wonder how the gears turn underneath our all-pervasive apps for entertainment. Today we'll look at one specific piece of the machinery: latency.

    Let's say you're making a video of someone's birthday party with an app on your phone. Once the recording starts, you don't care when the app starts writing it to disk—as long as everything is there in the end.

    However, if you're having a Skype call with your friend, it matters a whole lot how long it takes for the video to reach the other end and vice versa. It's impossible to have a conversation if the lag (latency) is too high.

Kraft out of KDE

Filed under
KDE
Software

Following my last blog about Krafts upcoming release 0.80 I got a lot of positive reactions.

There was one reaction however, that puzzles me a bit and I want to share my thoughts here. It is about a comment about my announcement that I prefer to continue to develop Kraft on Github. The commenter reminded my friendly that there is still Kraft code on KDE infrastructure, and that switching to a different repository might waste peoples time when they work with the KDE repo.

That is a fair statement, of course I don’t want to waste peoples time. What sounds a bit strange to me is the second paragraph, that says that if I decide to stay with Github, I should let KDE people know that I wish Kraft to not be a KDE project anymore.

But … I never felt that Kraft should not be a KDE project any more.

  • How to dual-boot Linux and Windows
    Even though Linux is a great operating system with widespread hardware and software support, the reality is that sometimes you have to use Windows, perhaps due to key apps that won't run under Linux. Thankfully, dual-booting Windows and Linux is very straightforward—and I'll show you how to set it up, with Windows 10 and Ubuntu 18.04, in this article. Before you get started, make sure you've backed up your computer. Although the dual-boot setup process is not very involved, accidents can still happen. So take the time to back up your important files in case chaos theory comes into play. In addition to backing up your files, consider taking an image backup of the disk as well, though that's not required and can be a more advanced process.

  • Openlab: what it is and why it matters
    Six months on from its announcement at Openstack Summit Sydney in late 2017, community testing project OpenLab is in full swing. OpenLab was initially formed by Intel, Huawei and the OpenStack foundation as a community-led project for improving SDK support and also introducing other platforms like Kubernetes and Cloud Foundry to the Openstack environment. Ultimately the idea is to improve usability in hybrid and multi-cloud environments. Melvin Hillsman sits on the governance board along with Dr Yih Leong Sun of Intel and Chris Hoge from the Foundation. Hillsman moved from Rackspace to Huawei to work specifically on the project. "The reason we think Openlab is important is, basically, Openstack for some time has been very specific about testing and integration for Openstack services, focusing only on the projects started at Openstack," Hillsman tellsComputerworld UK at the Openstack Vancouver Summit. "It's been working very well, it's a robust system. But for me as a person in the user community - my getting involved in Openstack was more on the operator-user side.
  • Open source innovation tips for the customer-driven economy
    New technologies, ranging from big data and blockchain to 3D printing, are giving rise to new opportunities and challenges for companies today. To stay competitive, organizations need to become more intelligent, customer-centric, and increasingly agile to cope with changing business demands. The worry for many companies which are trying to innovate is that while the speed and scope of applications are expanding rapidly, the variety and complexity of technology is increasing simultaneously, putting pressure on their IT infrastructure. Speaking at the SUSE Expert Days 2018 held in Singapore recently, Dr Gerald Pfeifer, VP of Products and Technology Program, SUSE, told attendees that these prevailing trends have come together to make Open Source the primary engine for business innovation.
  • Qualcomm is able to release the Snapdragon 845 source code in 6 weeks
    Qualcomm‘s latest high-end system-on-chip, the Qualcomm Snapdragon 845, was announced at the Snapdragon Tech Summit back in December. The chipset offers 4 Kryo 385 (A75 “performance”) and 4 Kryo 385 (A55 “efficiency”) CPU cores, the latest Adreno 630 GPU, the Spectra 280 ISP, the Hexagon 685 DSP, the Snapdragon X20 LTE modem, and a new Secure Processing Unit (SPU). The Snapdragon 845 SoC is a powerhouse in benchmarks and it is already available in devices like the Samsung Galaxy S9/S9+, Xiaomi Mi Mix 2S, and the OnePlus 6. Developers on our forums have been itching to get their hands on a device with Qualcomm’s latest and greatest, but there’s just one thing that has made some developers worry about the future of development on the platform: The lack of publicly available source code for the kernel, HALs, framework branches, and more on the CodeAurora Forums.

  • What's new in OpenStack?
    As OpenStack Foundation Chief Operating Officer Mark Collier referenced in his opening keynote, the uses which OpenStack is seeing today expand far beyond what most who were involved in the early days of the project could have ever imagined. While OpenStack started out primarily in the traditional data center and found many large-scale users, particularly in the telecommunications industry, who were using it to manage huge installations of traditional x86 server hardware, the flexibility of OpenStack has today allowed it to thrive in many other environments and use cases. Today, we see OpenStack powering everything from academic and research projects to media and gaming services, from online retail and e-commerce to manufacturing and industrial applications, and from finance to healthcare. OpenStack is found in all of these different places not just because it is cheaper than using the public cloud, not just because it makes compliance with various regulations easier, but because its open source code makes it flexible to all sort of different situations.
  • Should Red Hat Buy or Build a Database?
    For a decade, at least, observers of the company have speculated about whether Red Hat would or should enter the database market. The primary argument, one made in this space eight years ago, has historically been that Red Hat is de facto leaving potential dollars on the table by limiting itself to operating platform and immediately adjacent markets. In a more recent piece, analyst Krishnan Subramanian adds that Red Hat is at risk because databases represent a control point, one that the company is effectively ceding to competitors such as AWS or Microsoft.
  • Tidelift Raises $15M Series A From General Catalyst, Foundry, & Others
    This morning Tidelift, a startup focused on helping developers work with open source technology, announced that it has closed a $15 million Series A round of funding co-led by General Catalyst, Foundry, and Matthew Szulik, the former CEO of Red Hat, a public open source-centered technology company. The subscription-powered startup has an interesting business model which we’ll dive into shortly, but it’s worth noting that the open source space as a whole is quite active. It’s something that Crunchbase News covered last year, describing how startups working with open source software have enjoyed a dramatic rise in investor interest. That puts Tidelift in the midst of a trend.
  • Tidelift lands $15M to deliver professional open-source support
    Tidelift Inc. is raising $15 million as it looks to boost its unique open-source software model that sees companies pay for professional support of their favorite projects, allowing those that maintain them to get compensated too. The Series A round was led by the investment firms General Catalyst and Foundry Group, as well as former Red Hat Inc. Chairman and Chief Executive Matthew Szulik. The company was able to attract the investment after coming up with a novel idea for maintaining the most popular open-source software projects in a way that benefits both the users and those who help to create them. It works like this: Companies pay a subscription fee that entitles them to professional-grade support, similar to the kind of commercial subscriptions offered by firms such as Red Hat, Cloudera Inc. and Docker Inc. A part of these fees are then used to pay the developers who maintain the software. The net result, at least in theory, is that everyone is happy, as companies enjoy the benefits of professional support at lower rates than they might expect from an established firm, and the developers of the software are finally rewarded for their efforts.
