  • Qt 3D Studio 1.0 Released

    We are happy to announce that Qt 3D Studio 1.0 has now been released. Qt 3D Studio provides a 3D user interface authoring system that caters for both software developers and graphic designers.

  • Qt 3D Studio 1.0 Released, Powered By NVIDIA's Open-Source Code

    The Qt Company is today shipping Qt 3D Studio, its new 3D user-interface authoring system for both developers and designers.

    Qt 3D Studio 1.0 has a Studio Editor for creating interactive 3D presentations and applications, the Qt 3D Studio Viewer for testing new 3D designs in action, and is supported across Windows / macOS / Linux.

    Of course, this new 3D Studio is powered by the Qt5 tool-kit. This new software package is made possible and based upon NVIDIA's huge code contribution to Qt earlier this year of opening the NVIDIA DRIVE Design Studio that became the basis for Qt 3D Studio.

  • KDE's Goals for 2018 and Beyond
  • KDE's Goals for 2018 and Beyond

    The KDE community has spoken and it has chosen the proposals which will define the general direction of the KDE project over the next three or four years.

    How does the KDE community decide where it wants to take the project? Well, every once in a while, we hold a Request for Proposals, if you will. All members of the community are encouraged to submit their grand ideas which will lay out long-term targets. Proposals are voted on democratically, again, by the community. This ensures it is truly the community that guides the KDE project to wherever the community wants it to go.

Cutelyst 1.11.0 released!

Filed under
KDE

Cutelyst the Qt Web framework got a new release, this is likely to be the last of the year and will be one of lasts releases of the 1.x.x series. I’d like to add HTTP/2 support before branching 1.x.x and having master as 2.0 but I’m not yet sure I’ll do that yet.

For the next year I’d like to have Cutelyst 2 packaged on most distros soon due Ubuntu’s LTS being released in April, and H2 might delay this or I delay it since it can be done using a front-end server like Nginx.

KDE’s Goal: Privacy

Filed under
KDE
Security

In the past, KDE software has come a long way in providing privacy tools, but the tool-set is neither comprehensive, nor is privacy its implications widely seen as critical to our success in this area. Setting privacy as a central goal for KDE means that we will put more focus on this topic and lead to improved tools that allow users to increase their level of privacy. Moreover, it will set an example for others to follow and hopefully increase standards across the whole software ecosystem. There is much work to do, and we’re excited to put our shoulder under it and work on it.

  • Qt 5.10 Release Candidate Arrives Late

    Qt 5.10 RC was expected back on 16 November but only this morning is making its debut.

    While arriving nearly two weeks late, The Qt Company is still hoping to get the official Qt 5.10.0 release out on time, which has been scheduled for 30 November. Thus there's basically two days left to get the release candidate tested if getting the release out on time.

  • Qt 5.10.0 RC out

    We are targeting to get final Qt 5.10.0 out 30.11.2017 as planned so please test the packages now & report me immediately if you find something which should really block the release. But remember: We won't block the release without really good reasons. Qt 5.10.1 will be released quite quickly so if we can live with issue as known issue in Qt 5.10.0 we will. So please add those issues directly in known issues page (https://wiki.qt.io/Qt_5.10.0_Known_Issues).

  • Evolving KDE – The goals are set!

    Since Akademy in Almería we have been going through the process of defining goals for KDE for the next 3 to 4 years. Different ideas were proposed and refined. 10 of them made it into the community-wide vote to select 3 of them. Today I am proud to announce the result based on the 684 submitted votes.

  • KDE's Goals For The Next 3~4 Years

    Since this year's KDE Akademy conference, KDE developers have been plotting their vision for the next few years and recently wrapped up voting on what should be their three main goals to focus on over the next few years.

  • Krita Development Sprint 2017

    With all the turmoil the project experienced in 2017 it looked for a while as if we wouldn’t have a face to face meeting this year. But that’s not good for a project working on its fourth major release! We knew we really had to sit together, and finally managed to have a smaller than usual, but very productive, sprint in Deventer, the Netherlands from Thursday 23th to Sunday 26th.

    Not having been together since August 2016, we had an agenda stuffed with a enormous backlog of items. And since we’ve been working on new code for a long time ago, our bug tracker was also slowly dying from elephantiasis of the database.

    Let’s do the bug tracker first: we managed to close over 120 bugs! Not every bug that gets closed gets closed with a fix: the problem is that most bug reports are actually help requests from users, and many of the rest are duplicates, or requests for features that are irrelevant for Krita. Still, while triaging the list of open and unconfirmed bug reports, we managed to fix more than a dozen real bugs.

  • [Krita] Interview with Radian

    I tend to hate any of my artwork if it is more than 1-3 months old but there are a couple of exceptions. The Kiki painting I made for the artbook “Made with Krita” is one of them. I used a bunch of new tricks in here and probably made a few good choices by accident.

  • Porting Applications to Qt

    KDAB has unique experience in porting the code base for toolkits like Qt 3, Qt 4, Motif, Java, Tcl, GTK, .NET, MFC, and Photon to Qt 5. Porting legacy GUI toolkits to Qt 5 is a job where proven experience saves a lot of time.

  • QtVirtualKeyboard on Wayland

    For the last couple of years my focus was on the Osmocom project to bring Free Software to the world of telecommunication. With a group of enthusiasts we have implemented the components necessary to run a complete network using Free Software. The Rhizomatica project is using the software to connecting people that were left behind. Our tools enabled high impact security research leading, leading to improvements to privacy and security for all of us….

    But during the last months I had the opportunity to return to C++ and Qt work and it feels like coming home to the world of ARM powered hardware. When I left, the transition from consumer electronics (e.g. settop boxes) to automative (e.g. IVI) began and it seems it successfully completed! On Friday I explored a regression in OpenSSL and today I had the pleasure to understand input method handling of wayland a little bit better.

    I wanted to see if I can use wayland and run QtVirtualKeyboard only in the Compositor. I couldn’t find answers in the documentation and started to read the code. Once I understood how it should work, I found a simple example in QtWayland. Isn’t Qt wonderful?

Linux Foundation: Real-Time Linux (RT Linux), LF Deep Learning Foundation, OpenTracing and More

  • Developers: Prepare Your Drivers for Real-Time Linux
    Although Real-Time Linux (RT Linux) has been a staple at Embedded Linux Conferences for years -- here’s a story on the RT presentations in 2007 -- many developers have viewed the technology to be peripheral to their own embedded projects. Yet as RT, enabled via the PREEMPT_RT patch, prepares to be fully integrated into the mainline kernel, a wider circle of developers should pay attention. In particular, Linux device driver authors will need to ensure that their drivers play nice with RT-enabled kernels. At the recent Embedded Linux Conference in Portland, National Instruments software engineer Julia Cartwright, an acting maintainer on a stable release of the RT patch, gave a well-attended presentation called “What Every Driver Developer Should Know about RT.” Cartwright started with an overview of RT, which helps provide guarantees for user task execution for embedded applications that require a high level of determinism. She then described the classes of driver-related problems that can have a detrimental impact to RT, as well as potential resolutions. One of the challenges of any real-time operating system is that most target applications have two types of tasks: those with real-time requirements and latency sensitivity, and those for non-time critical tasks such as disk monitoring, throughput, or I/O. “The two classes of tasks need to run together and maybe communicate with one another with mixed criticality,” explained Cartwright. “You must resolve two different degrees of time sensitivity.” One solution is to split the tasks by using two different hardware platforms. “You could have an Arm Cortex-R, FPGA, or PLD based board for super time-critical stuff, and then a Cortex-A series board with Linux,” said Cartwright. “This offers the best isolation, but it raises the per unit costs, and it’s hard to communicate between the domains.”
  • Clarifying the Linux Real Time Issue
    I recently posted an article about the increasing development and availability of Linux-powered automation devices. This is a clear industry trend that’s unavoidable for anyone following the automation technology industry. Shortly after posting the article, I heard from a reader who wrote: “I read your article and I am surprised that you would promote the idea that anyone would use Linux for anything critical. It isn’t even a real-time control system. It can be used for non-critical applications, but the article implies that industry is adopting it for everything.” This reader brings up a valid point. Linux is not a real-time OS in and of itself. As Vibhoosh Gupta of GE Automation & Controls noted in the original article, GE uses “Type 1 hypervisor technology to run a real-time OS, such as VxWorks, running traditional control loops alongside our PAC Edge technology operating on Linux.” [...] The Linux Foundation launched the RTL (Real Time Linux) Collaborative Project in October 2015. According to the Foundation, the project was “founded by industry experts to advance technologies for the robotics, telecom, manufacturing and medical industries. The aim of the RTL collaborative project is mainlining the PREEMPT_RT patch.” While there are plenty of mission critical applications running Linux OS with real-time extensions—as highlighted by GE, Opto and Wago—the Linux Foundation notes on its site that there remains “much work to be done.”
  • Linux Launches Deep Learning Foundation For Open Source Growth In AI
    The Linux Foundation has launched the LF Deep Learning Foundation, an umbrella organisation which will support and sustain open source innovation in artificial intelligence, machine learning, and deep learning. The organisation will strive to make these critical new technologies available to developers and data scientists everywhere, said a statement published by LF. Founding members of LF Deep Learning include Amdocs, AT&T, B.Yond, Baidu, Huawei, Nokia, Tech Mahindra, Tencent, Univa, and ZTE, among others. LF Deep Learning, members are working to create a neutral space where makers and sustainers of tools and infrastructure can interact and harmonise their efforts and accelerate the broad adoption of deep learning technologies.
  • OpenTracing: Distributed Tracing’s Emerging Industry Standard
    What was traditionally known as just Monitoring has clearly been going through a renaissance over the last few years. The industry as a whole is finally moving away from having Monitoring and Logging silos – something we’ve been doing and “preaching” for years – and the term Observability emerged as the new moniker for everything that encompasses any form of infrastructure and application monitoring. Microservices have been around for a over a decade under one name or another. Now often deployed in separate containers it became obvious we need a way to trace transactions through various microservice layers, from the client all the way down to queues, storage, calls to external services, etc. This created a new interest in Transaction Tracing that, although not new, has now re-emerged as the third pillar of observability.

  • Hackers Leaked The Code Of iPhone Cracking Device “GrayKey”, Attempted Extortion
    The mysterious piece of hardware GrayKey might give a sense of happiness to cops because they can get inside most of the iPhone models currently active, including the iPhone X. The $30,000 device is known to crack a 4-digit iPhone passcode in a matter of a few hours, and a six-digit passcode in 3 days, or possibly 11 hours in ideal scenarios. That’s why security experts suggest that iOS users should keep an alphanumeric passcode instead of an all-number passcode.
  • Someone Is Trying to Extort iPhone Crackers GrayShift With Leaked Code
    Law enforcement agencies across the country are buying or have expressed interest in buying GrayKey, a device that can unlock up-to-date iPhones. But Grayshift, the company that makes the device, has attracted some other attention as well. Last week, an unknown party quietly leaked portions of GrayKey code onto the internet, and demanded over $15,000 from Grayshift—ironically, the price of an entry-level GrayKey—in order to stop publishing the material. The code itself does not appear to be particularly sensitive, but Grayshift confirmed to Motherboard the brief data leak that led to the extortion attempt.
  • It's not you, it's Big G: Sneaky spammers slip strangers spoofed spam, swamp Gmail sent files
    Google has confirmed spammers can not only send out spoofed emails that appear to have been sent by Gmail users, but said messages also appear in those users' sent mail folders. The Chocolate Factory on Monday told The Register that someone has indeed created and sent spam with forged email headers. These not only override the send address, so that it appears a legit Gmail user sent the message, but it also mysteriously shows up in that person's sent box as if they had typed it and emitted themselves. In turn, the messages would also appear in their inboxes as sent mail.
  • Cilium 1.0 Advances Container Networking With Improved Security
    For last two decades, the IPtables technology has been the cornerstone of Linux networking implementations, including new container models. On April 24, the open-source Cilium 1.0 release was launched, providing a new alternative to IPtables by using BPF (Berkeley Packet Filter), which improves both networking and security. The Cilium project's GitHub code repository defines the effort as Linux Native, HTTP Aware Network Security for Containers. Cilium development has been driven to date by stealth startup Covalent, which is led by CEO Dan Wendlandt, who well-known in the networking community for his work at VMware on software-defined networking, and CTO Thomas Graf, who is a core Linux kernel networking developer.

  • KStars 2.9.5 is out!
    Autofocus module users would be happy to learn that the HFR value is now responsive to changing seeing conditions. Previously, the first successful autofocus operation would set the HFR Threshold value of which subsequent measurements are compared against during the in-sequence-focusing step.
  • Kurly – An Alternative to Most Widely Used Curl Program
    Kurly is a free open source, simple but effective, cross-platform alternative to the popular curl command-line tool. It is written in Go programming language and works in the same way as curl but only aims to offer common usage options and procedures, with emphasis on the HTTP(S) operations. In this tutorial we will learn how to install and use kurly program – an alternative to most widely used curl command in Linux.
  • Pamac – Easily Install and Manage Software on Arch Linux
    Arch Linux is one of the most popular Linux distribution available despite its apparent technicality. Its default package manager pacman is powerful but as time always tells, it is a lot easier to get certain things done using a mouse because GUI apps barely require any typing nor do they require you to remember any commands; and this is where Pamac comes in. Pamac is a Gtk3 frontend for libalpm and it is the GUI tool that Arch Linux users turn to the most when they aren’t in the mood to manage their software packages via the terminal; and who can blame them? It was specifically created to be used with Pacman.
