  • Device Tailored Compositors with Qt Wayland at CLAAS E-Systems

    Have you heard about software in cars that run on embedded devices? Do you think that creating such software might be challenging? Well, welcome to a complete new world of complexity, welcome to the world of agriculture machines! For many years, automatic steering (on fields), terminals to control the complex mechanical operations of a self-driving 16 ton combine harvester on a soft ground, and self-optimization systems to optimize any tiny bit of your harvester, are key demands from customers. I, myself, am working at CLAAS E-Systems, the electronics and software department within the CLAAS group. Our group is well known for being among the leading manufacturers for combine harvesters, tractors and forage harvesters.

  • Qt Wayland Is Next Appearing On Tractors & Farm Equipment

    With Qt 5.8's Qt Wayland Compositor Framework taking shape, more developers are beginning to tailor a Qt Wayland compositor to their use-cases. One of those is a company specializing in farm equipment like combine harvesters, tractors, and harvesters.

    As a guest post on the official Qt blog, developer Andreas Cord-Landwehr of CLAAS E-Systems talked up Qt Wayland for their purposes in the highly-regulated agriculture industry.

  • KDE ideas – A better browser

    The first thing I have to do when I log into KDE is move Firefox windows to the activities they ought to be in. One to Programming, another to Writing, Administration, Internet, etcetera. KDE deserves a browser that takes advantage of activities and other features of the Plasma Desktop.

    I want to thank the people who worked so hard to create Krita and keep making it better and better. Thank you for this opportunity to show my work here and I appreciate all the encouragement and support I have received from my friends and family. I hope my art can encourage more people to paint with Krita and develop their talent and creativity. If there is any way I can contribute to making Krita better, I would be most happy to help!

  • Almost perfect HiDPI experience on Linux (Xorg)

    In 2013 I bought a Macbook Pro 13” which came with a HiDPI display (also known as retina display). Already back then the support for a single HiDPI display was quite alright with KDE4 and a few tweaks here and there. Months later Qt5 got native HiDPI support and most applications switched from GTK2 to GTK3 and finally the outliers (chromium based apps, godot, arduino…) got support for higher DPIs as well.

  • The Opening of the First KDE Slimbook

    Fresh off the production line from 101’s factory in València is the first KDE Slimbook which I opened today at FLOSS UK conference here in Manchester.

  • The First KDE Slimbook Unboxing Video Appears Online

    If you’ve been itching to see more of the KDE Slimbook, the ultra-thin laptop announced by Spanish company Slimbook back in January, then you’re in luck.

    KDE developer (and all-round awesome chap) Jonathan Riddell snagged some one-on-one time with the bespoke KDE-branded laptop at the FLOSS Spring 2017 conference taking place in Manchester.

    “Fresh off the production line from 101’s factory in València is the first KDE Slimbook which I opened today at FLOSS UK conference here in Manchester,” he writes in a short blog post.

KDE

We are excited to announce the first Chakra release of 2017, codenamed Goedel, to honor the logician, mathematician and philosopher Kurt Goedel.

The 2017.03 release introduces two noteworthy changes:
- The installer, Calamares, has been updated to version 3.0.1.91. As a result, users are now able to install Chakra on btrfs and LUKS encrypted partitions. Calamares has received lots of partitioning enhancements and bug fixes since our previous ISO release and the installation process should be smoother than ever.

    For the part one, the custom commands were possible thanks to Google Actions Apis. I used API.AI for my purpose since they had good documentation. I wont go into detail explaining the form fields in Api.ai, they have done a good job with documentation and explaining part, I will just share my configurations screenshot for your quick reference and understanding. In Api.ai the conversations are broken into intents. I used one intent (Default Welcome Intent) and a followup intent (Default Welcome Intent – custom) for my application.
  • Google Assistant SDK preview brings voice agent to the Raspberry Pi
    Google has released a Python-based Google Assistant SDK that’s designed for prototyping voice agent technology on the Raspberry Pi 3. Google’s developer preview aims to bring Google Assistant voice agent applications to Linux developers. The Google Assistant SDK is initially designed for prototyping voice agent technology on the Raspberry Pi 3 using Python and Raspbian Linux, but it works with most Linux distributions. The SDK lets developers add voice control, natural language understanding, and Google AI services to a variety of devices.
  • Huawei, Google create a high-powered single board computer for Android
    The Raspberry Pi is very popular with DIY enthusiasts because of the seemingly endless possibilities of how you can design devices with it. Huawei and Google have created their own single board computer (SBC), but this will probably benefit Android developers more than DIY enthusiasts. The HiKey 960 is a very robust SBC aimed at creating an Android PC or a testing tool for Android apps.

  • Light a fire under Cassandra with Apache Ignite
    Apache Cassandra is a popular database for several reasons. The open source, distributed, NoSQL database has no single point of failure, so it’s well suited for high-availability applications. It supports multi-datacenter replication, allowing organizations to achieve greater resiliency by, for example, storing data across multiple Amazon Web Services availability zones. It also offers massive and linear scalability, so any number of nodes can easily be added to any Cassandra cluster in any datacenter. For these reasons, companies such as Netflix, eBay, Expedia, and several others have been using Cassandra for key parts of their businesses for many years.
  • Proprietary Election Systems: Summarily Disqualified
    Hello Open Source Software Community & U.S. Voters, I and the California Association of Voting Officials, represent a group of renowned computer scientists that have pioneered open source election systems, including, "one4all," New Hampshire’s Open Source Accessible Voting System (see attached). Today government organizations like NASA, the Department of Defense, and the U.S. Air Force rely on open source software for mission critical operations. I and CAVO believe voting and elections are indeed mission-critical to protect democracy and fulfill the promise of the United States of America as a representative republic. Since 2004, the open source community has advocated for transparent and secure—publicly owned—election systems to replace the insecure, proprietary systems most often deployed within communities. Open source options for elections systems can reduce the costs to taxpayers by as much as 50% compared to traditional proprietary options, which also eliminates vendor lock-in, or the inability of an elections office to migrate away from a solution as costs rise or quality decreases.

  • Creative Commons Is Resurrecting Palmyra
    Creative Commons launched its 2017 Global Summit today with a rather moving surprise: a seven-foot-tall 3D printed replica of the Tetrapylon from Palmyra, Syria. For those who don't know the tragic situation, Palmyra is one of the most historic cities in the world — but it is being steadily destroyed by ISIS, robbing the world of countless irreplaceable artifacts and murdering those who have tried to protect them (the folks at Extra History have a pair of good summary videos discussing the history and the current situation in the city). Among ISIS's human targets was Bassel Khartabil, who launched Syria's CC community several years ago and began a project to take 3D scans of the city, which CC has been gathering and releasing under a CC0 Public Domain license. He was captured and imprisoned, and for the past five years his whereabouts and status have been unknown. As the #FreeBassel campaign continues, Creative Commons is now working to bring his invaluable scans to life in the form of 3D-printed replicas, starting with today's unveiling of the Tetrapylon — which was destroyed in January along with part of a Roman theatre after ISIS captured the city for a second time.
