  • KDE's Project Neon Begins Publishing Daily Wayland Images

    KDE --
    KDE's Project Neon has begun publishing daily images of the latest KDE Plasma stack powered atop Wayland rather than the X.Org Server.

    Jonathan Riddell passed along word that daily ISOs are now being spun of the freshest KDE development code with KWin acting as a Wayland compositor. The OS base is still Ubuntu 16.04 LTS.

  • The Qt Company's Qt Start-Up

    The Qt Company is proud to offer a new version of the Qt for Application Development package called Qt Start-Up, the company's C++-based framework of libraries and tools that enables the development of powerful, interactive and cross-platform applications and devices.

  • KDE Akonadi Support For Microsoft Exchange
  • Akonadi Resource for Microsoft Exchange Web Services (EWS)

    Whether you are a Microsoft hater or a lover, when you have ever had a chance to work for a medium or large corporation, you have probably stumbled upon Microsoft Exchange mail server. While it can be made to talk to regular e-mail clients using standards such as IMAP, POP3 and SMTP, some corporate admins choose not to enable any of the standard mail protocols leaving the user with no choice other than to use Microsoft Outlook. Even if it is possible to use regular e-mail clients they will not be able to explore the full potential of Exchange, as it is not only a mail server but rather a groupware server which includes support for calendar, tasks, contacts and many more.

  • Evaluation of the Qt Quick Scene Graph Performance

    QPainter, which is the base of drawing in KStars, uses an imperative way whereas QtQuick Scene Graph utilizes declarative paradigm. In Scene Graph you add some set of "nodes" (classes with prefix QSG) to the root node that is returned by calling QQuickItem::updatePaintNode() whenever you want to render QQuickItem and manipulate them during the runtime (change position, geometry, material, etc.) This gives possibilities to perform some optimization like batching the nodes to draw them in fewer calls to OpenGL, which can be of tremendous help for us in drawing stars, for example.

  • Hello World!

    As the title suggests it is a lite version for mobile/tablets, slow machines like budget laptops, netbooks, single-board computers like Raspberry Pi, etc. One of the main differences between desktop and lite versions is that the graphics of the latter is based on QML/QtQuick. KStars Lite is built bearing in mind the differences between mouse/touch interfaces and the graphical frontend will be designed according to touch interfaces of mobile platforms.

  • A KMail Breakthrough.

    This tells the story of how I finally managed a successful transfer of email data from KMail version 1.13.6 to version 4.11.5. It is a non-technical essay exploring the obstacles I encountered, my options, and the methods I used to achieve my aim. It was written partly to give the information, but also with the hope that readers will both enjoy and be amused by the story of the "battle of KMail" that was ultimately won against "incredible odds". Links to the earlier articles discussing problems with KMail 4x are given at the end.

  • [GSoC] Kdev-Embedded, Debugging and programming embedded systems

    The actual embedded system word depends on closed-source IDEs and libraries, with high monetary value and deprecated functionalities. Programmers that would like to use ARM based boards without paying for an IDE will have problems setting up such development ambient and synchronized toolkits.

    The main idea of this project is to provide a plugin integrated with KDevelop to help the debugging and programming process of embedded systems like AVR, ARM and x86 based boards.

Taming Plasma

Filed under
KDE

How does one go about taming Plasma? Well, that seems to be a recurring question I get asked in the emails. People are really interested to know about theme, font, icon, and window decoration management in Plasma, and how it compares to the good ole KDE4. A valid question.

We already know quite a bit about this desktop environment. I was extremely keen on Plasma last year, and even crowned it my favorite for a while. We also talked about some neat tips and tricks on managing the desktop, so it’s not a stranger. Now, we shall delve deeper into the aesthetics side of things.

  • A Usability Guy’s Journey to Creating his First KDE Tool – Part 2: A Vision

    The nice thing is that we can reuse the information for AppStream to automatically create a website for each application which is at least a lot more informative for end users than what quickgit provides. Of course, those projects who have the manpower and motivation to create gorgeous websites like that for Minuet or Krita should still do that, but the others would still get at least something useful.

  • Kronometer 2.1 now available

    After many months since the last release, I’ve finally found the time to finalize the next stable release for kronometer. The main change is a redesign of the main window. The toolbar is now smaller and in top position, the statusbar is gone and the menubar is hidden by default. Usability of other dialogs has been improved as well.

  • Performance update for breeze icons

    As breeze is a monochrome icon set the contrast is one of the biggest issues. With Plasma 5.6, the developers solved this problem by applying the system color scheme to the icons. Now the icons use the same color (and contrast) as the text. With this shiny new feature, users can define the colors of the icon set by themselves.

  • Google Summer of Code, 2016

    Well, the wait for the results of Google Summer of Code 2016 is over. My proposal has been accepted and is a GSoC project now. I will be spending the summer writing code for KDE for implementing the project Minuet Mobile(KDE-edu).

  • KDE is not the right place for Thunderbird [Ed: This post, "KDE is not the right place for Thunderbird," has just been deleted. One wonder what happened. Maybe pressure from peers?]

    For years, Mozilla has been saying they are no longer focused on Thunderbird and its place is outside of Mozilla. Now it seems they are going to act on what they said: Mozilla seeks new home for e-mail client Thunderbird.

    The candidates they are exploring are the Software Freedom Conservancy, The Document Foundation, and I expect at least the Apache Software Foundation to be a serious candidate, and Gnome to propose.

  • open365, let's declare war at Google and Microsoft

    Open365 is a public and/or private cloud designed to compete with the likes of Google Drive or Office365 by leveraging all the best free software out there.

    The service is designed to scale horizontally as well as to be resilient to components crashing or going crazy. In order to achieve this we have implemented a microservice architecure that communicate using a bus (rabbitmq) plus some other tricks so we can scale using commodity hardware horizontally. Nothing fancy, nothing revolutionary but it had to be done Smile

    Finally, we’ve integrated under the same system very well know software solutions for File sinchronization, PIM (Email, calendar,contacts…) and office.

    Specifically

    Seafile
    Kontact
    Libreoffice

    For the last two, we re using SPICE and our HTML5/Javascript client to run those applications in the server and send only the interface to the Web browser in a really efficient way.

After it went down in the middle of CKI - and resulted in a few embarrassing moments in the middle of talks - we decided it had to go.

  • Reordering a Qt Quick ListView via drag'n'drop

    It is common in user interfaces to provide the user with a list of elements which can be reordered by dragging them around. Displaying a list of elements with Qt Quick is easy, thanks to the ListView component. Giving the user the ability to reorder them is less straightforward. This 3 article series presents one approach to implementing this.

I would like to thank KDE community, my mentor, and co-mentors for their support and giving me an opportunity to be a part of this programme. I will be working on the project LabPlot (KDEdu) which is a KDE-application for interactive graphing and analysis of scientific data. LabPlot provides an easy way to create, manage and edit plots.

  • Linux Unable To Boot Lenovo Yoga 900 & 900; Is Microsoft At Fault?
    The popular device developer Lenovo has verified the claims that Lenovo Yoga 900 and 900s unable to boot Linux OS but only Microsoft Windows 10. The new Lenovo convertible laptop, Lenovo Yoga 900 and 900s, would reject and decline any attempt to install Linux operating system, making users turn their heads to Microsoft as the suspect for this issue. [...] This issue about the OS started when an identity of BaronHK posted on Reddit about installing Linux on the latest Lenovo Yoga book in which BaronHK encountered being blocked by a locked solid state drive (SSD) which Linux cannot define itself, and come up to link the issue to Microsoft.

    Today, September 30, 2016, renowned Linux kernel developer Greg Kroah-Hartman announced the release of the sixth maintenance update to the latest stable Linux 4.7 kernel series. Linux kernel 4.7.6 comes only five days after the release of the previous maintenance version, Linux kernel 4.7.5, and, according to the appended shortlog and the diff from the last update, it changes a total of 76 files, with 539 insertions and 455 deletions. In summary, it updates multiple drivers, adds improvements to various filesystems and hardware architectures, and improves the networking stack.
  • Linux Kernel 4.4.23 LTS Has ARM and MIPS Improvements, Updated Filesystems, More
    Immediately after announcing the release of Linux kernel 4.7.6, Greg Kroah-Hartman proudly informed the community about the general availability of the Linux 4.4.23 LTS kernel. The Linux 4.4 kernel is a long-term supported branch, the latest and most advanced one, used in many stable and reliable GNU/Linux operating systems, including Ubuntu 16.04 LTS (Xenial Xerus) and Alpine Linux 3.4. Therefore, it is imperative for it to receive regular updates that bring fixes to the most important issues, as well as other general improvements.

    BUS1 has been in development as an in-kernel IPC mechanism building off the failed KDBUS project. An "RFC" will soon be sent out to Linux kernel developers about BUS1 and the subject will be discussed at next month's Kernel Summit. David Herrmann, one of the BUS1 developers, presented at this week's systemd.conf conference about the new capability-based IPC for Linux. He talked about how BUS1 is superior to KDBUS, how BUS1 is similar to Android's Binder, Chrome's Mojo, Solaris' Doors, and other common IPC implementations.
  • A New Wireless Daemon Is In Development To Potentially Replace wpa_supplicant
    In addition to the BUS1 presentation, also exciting from the systemd.conf 2016 conference is a thorough walkthrough of a new wireless daemon for Linux being developed by Intel's Open-Source Technology Center. Intel has been developing a new wireless daemon for Linux to potentially replace wpa_supplicant. This new daemon isn't yet public but the code repositories for it will be opened up in the next few weeks. This new daemon has improvements around persistency, WiFi management, reduced abstractions for different operating systems and legacy interfaces, and changes to operation. This daemon is designed to be very lightweight and work well for embedded Linux use-cases especially, including IoT applications.
