Interviews

Back in 2010 while learning game development and programming, I was looking for a free tool for 2D graphics. After some research, I settled with GIMP.

Krita has the most important feature for any digital artist out there. Freedom of choice. Almost every important aspect of the UI, brushes or workflow is customizable. It’s literally like my own physical studio where I can put things where they belong because it suits me. Missing something? Write a plugin.

Also, the previously mentioned Wrap Around Mode is incredibly useful and time-saving.

[KDE] Packaging updates in FreeBSD

Filed under
KDE

We’re in the process of packaging poppler 0.82, which (as usual) leads to some breakage in consumers of that package – things like editors/calligra – so there will be more updates soon-ish. I think I independently re-created a patch for LibreOffice to fix the build already (turns out there was a patch in Gerrit already).

Looking in or looking out?

Development
KDE
Software
OSS

In my previous blog post, I mentioned that being part of the wider Free Software community can be a drag on a project.

In this post, I want to put that in perspective. Elaborate a bit, if you will.

For someone like me who wrote his first GPL’ed application in 1993 (it was a uucp mail and usenet client written in –gasp!– Visual Basic), I’ve spent countless hours pleasantly occupied contemplating the where and which of Free Software. I am part of the KDE community, the Libre Graphics community, the Free Software community. Inside our communities, we’ve got engrossing discussions about licensing, diverting flamewars about business models, scintillating technical developments, awesome foes to smite, forks to be praised or lambasted. There are conferences to be visited, or be perorated at, sprints to organize and organizations to join.

In short, you can develop Free Software within the Free Software community while all the while looking in. This is important for Free Software. That is bad for Free Software. If I make this effort, or take this initiative, or mentor this student, Free Software will improve.

And that’s fun, and gives one the satisfied feeling of making the world a better, freer place. And I care about software freedom, really I do!

It does take a lot of time, though, and that time — is that really spent making the world better for the people who use my software? Is all that caring about the ins and outs of the Free Software community the best use of my time, when I’m working on an end-user application? And does it give me the right kind of insight in what I should be doing?

That’s what I meant when I wrote that I was kind of agreeing with Ton that being part of the Free Software community could be a drag on Krita becoming successful.

If I’m spending my time on GNOME vs KDE, Flatpak vs Snap vs AppImage, deb vs RPM, then I’m only worrying about technical details that don’t mean a thing for someone who wants to paint a comic. That makes it at worst a waste of my time, or at best a hobby that is only tangentially related to Krita and its users.

If I’m looking inside the community, and not out of it, facing the people who will actually be using my software, I probably won’t be making the right kind of software.

Qt 3D in Qt 6

  • What about Qt 3D in Qt 6?

    In the previous article we described the changes to Qt 3D that are already in recent Qt 5 versions or in upcoming ones. This article will explain the work that is going on towards the major changes for Qt 3D in Qt 6.

    There are many things we would like to improve in Qt 3D for Qt 6 but here I will focus on a couple of the big ones: caching renderer work and modern graphics APIs like Vulkan, Metal and DirectX 12.

  • The Qt 3D Story With Vulkan Should Be Quite Compelling For Qt 6.0

    With the soon to be released Qt 5.14 is the start of their new high-level 3D API that itself is graphics API independent for being able to target the likes of Apple Metal and Vulkan as well as Direct3D and still falling back to OpenGL. The start of the graphics API independent scenegraph renderer is turning out well for Qt 5.14 but there will be more to come in the spring with Qt 5.15 while at the end of next year with Qt 6.0 should be a much more compelling story.

    The work going into Qt Quick 3D and all of the new graphics API independent work for this leading cross-platform toolkit is very exciting. As well, Qt 3D (non Qt Quick 3D) will continue to be advanced too for those wanting more control over the 3D programming process.

Plasma Mobile now uses the same notification code that is used on the desktop, which has received some slight adjustments when running on a phone (Marco Martin).

The dialer now uses the SearchField component from Kirigami, giving it the same look and feel as in similar places (Jonah Brüchert).

The icons in the top drawer are consistently monochrome now (Nicolas Fella).

LabPlot 2.7 released

Filed under
KDE

We are happy to announce the release of LabPlot 2.7. The biggest effort in this version went into improving the user experience to make working with LabPlot easier and fun.

The Spreadsheet is where plots get data from. It consists usually of columns containing the imported data or the data entered manually by the user. Besides this, the content of a calculated column in the spreadsheet is computed using a mathematical expression applied to the content of other columns in the same spreadsheet.

Such calculated columns are now more flexible and react to data changes in the parameter columns when they get deleted or re-added. When such changes occur the content of the calculated column is properly updated or invalidated.

The Functions Values dialog is where calculated columns are defined. A red-highlight in this dialog indicates that one of the parameter columns in a calculation was deleted from the project. This dialog also prevents selecting the calculated column as a parameter column and thus avoids circular dependencies.

  • Ubuntu Podcast from the UK LoCo: S12E33 – The Sentinel

    This week we’ve been to the Linux Application Summit in Barcelona. We round up news from the Ubuntu and desktop Linux community and bring you our picks from the wider tech news. It’s Season 12 Episode 33 of the Ubuntu Podcast! Alan Pope, Mark Johnson and Martin Wimpress are connected and speaking to your brain.

  • Kubernetes and the misconception of multi-cloud portability
  • Linux 5.5 To Finally Expose NVMe Drive Temperatures Via HWMON

    Linux for years has supported monitoring NVMe drive temperatures when installing the nvme user-space utility and run as root, etc. But now finally with Linux 5.5 the kernel is supporting NVMe drive temperature reporting through the hardware monitoring "HWMON" infrastructure alongside other hardware sensors. Come the Linux 5.5 stable release in early 2020 is the NVMe HWMON support to allow reporting the current NVMe drive temperature sensor(s) and min/max thresholds via this kernel infrastructure. This in turn allows user-space to simply query the data over sysfs without the need for any utilities, no root requirement, and should gracefully work with the various programs that report HWMON sensor readings to Linux desktop users.

  • PHP 5.3 To PHP 7.4 Performance Benchmarks On AMD EPYC

    With the big PHP 7.4.0 release due out next week, yesterday we published our PHP 7.4.0 benchmarks using the near-final build for this annual update to PHP. Those benchmarks compared previous releases as far back as PHP 5.6. But out of curiosity after that article I went to do some benchmarks going back to PHP 5.3 through PHP 7.4 and PHP 8.0-dev. With the AMD EPYC 7642 server running Ubuntu 19.10 used in yesterday's article, I ran the final PHP 5.3/5.4/5.5 benchmarks added in to yesterday's data. So for those curious how the historical PHP5 performance compares to the imminent PHP 7.4, these benchmarks are for your enjoyment today.

  • Wine Patches Coming To Allow UMIP Emulation - Works Around Issues For Ryzen 3000

    Coming up this weekend with the Linux 5.4 kernel is emulation/spoofing of the SGDT/SIDT/SMSW instructions around UMIP for allowing newer 64-bit Windows games to run on Wine and Steam Play (Proton). With newer CPUs like the AMD Ryzen 3000 series that support UMIP, these instructions are not allowed to run in user-space with Wine due to UMIP. So while the first stable kernel release is about to land with this support, some Wine-based emulation not contingent on the kernel patches is also in the works.

  • KF6 Sprint - Day One

    Today we started our KF6 sprint at the MBition office in Berlin. Beside the people attending in person, we have David Faure joining us via web conference. Thanks already to the people at MBition that spend time on making it possible to host the sprint there. First stuff to be discussed were some high level things, like does the monthly release scheme work out well. Short answer: yes :) The short period works well, allows people to fix issues directly in frameworks and still have that reasonable fast provided to the users. And the overhead of release creation is low, thanks to automation.

  • Goldman Sachs is planning on giving some of its most valuable software to Wall Street for free

    Goldman Sachs wants to give away some of its most valuable software. The investment bank spent countless hours over 14 years developing a platform called Alloy to help it access and analyze the growing set of financial databases being created across the firm. Now Goldman is taking the unusual step of making that program, as well as the language underlying it, available to the rest of Wall Street for free as open-source software in collaboration with a nonprofit called Finos. The software and language "have grown to become critical tools within our firm across the trade lifecycle that help us price, assess and evaluate risk, clear transactions, and perform regulatory reporting," said Neema Raphael, co-chief data officer at Goldman. By making it publicly available, "we'll unlock tremendous value for the industry when we co-develop and share models."

  • Open source transparency comes to root of trust hardware

    Geopolitics have put enterprise data centers in the crosshairs of international espionage. From all corners of the globe, hackers of all sorts, including those aligned with national spy agencies, are zeroing in on hardware roots of trust. For any computing platform, the root of trust is the ultimate line of defense against cybersecurity attacks. No matter how secure your operating system and applications appear to be, they are acutely vulnerable if running on a hardware platform whose root of trust has been compromised by an unauthorized party.

  • Cloud Print becomes the latest product to face Google death squad

    At the end of 2020, after over a decade in beta, Google will pick up its product-ending shotgun and take Cloud Print for a talk behind the back shed, from which it will never return. "Beginning January 1, 2021, devices across all operating systems will no longer be able to print using Google Cloud Print," Google said in a support note. "We recommend that over the next year, you identify an alternative solution and execute a migration strategy." Last week for its own Chrome OS operating system, Google added CUPS printing, which it will use instead of Cloud Print.

  • Google shuts down its Cloud Print service after 10-year Beta

    Google revealed plans to shut down Cloud Print, a cloud-based printing solution, at the end of 2020 permanently. The company launched Cloud Print back in 2010 as a solution to print from any Internet connected device to compatible printers. The main benefit of the solution was that users did not have to install printer drivers on their client devices and that devices did not need to be in the same local network as the printer. The solution enabled printing on devices without official support from the printer's manufacturer or drivers for that particular device. On Windows users could install the Google Cloud Printer application to add cloud printing functionality to the operating system.

  • Google Cloud Print will be shut down on December 31, 2020

    After offering printing from any device, from any location, to any web-connected printer with Cloud Print, Google is shutting down the service that has technically been a beta product since 2010. Cloud Print will be gone by the end of next year and users will need to find an alternative before December 31, 2020. Chrome OS, which originally relied on Cloud Print entirely for printing needs, eschewing the need to develop native printing controls, is now going full native. Chrome OS already handles some administrative tasks for printers that use the Common Unix Printing System (CUPS). Google promises to expand administrative options through the end of the year, and add more robust support for external print servers and other security policy administration in 2020. Since Chrome OS and its apps relied entirely on Cloud Print, Google will also be developing APIs for third-party developers to handle printing tasks.

Why You Should Be Using Linux

How many times have you been happily working away when, out of nowhere, Windows either forced a reboot to update, stopped responding, or completely crashed? With Linux, those events are a thing of the past. Because of the way Linux was designed, you (the user) have complete control over nearly everything. Say, for example, an application fails on you. Instead of that application taking the entire desktop along for the ride (an issue that often stumps even software development providers), you can log into what’s called a virtual console and force that crashed application closed via the command line. Yes, that does take a bit more skill than the average user possesses, but once you know how it’s done, it becomes second nature. The likelihood of that actually happening, however, is low. The few instances where this has happened to me was due to my using beta or “nightly” releases of software, which the average user wouldn’t be working with. Linux simply works and works with an almost unheard of reliability. Read more

Industrial-grade Linux OS gets Over-the-Air updates

Modern embedded systems need a reliable and secure way to deliver software updates remotely. Toradex aims to accomplish this by publishing critical operating system updates to customers with devices running TorizonCore, an easy-to-use industrial-grade Linux OS. The system will provide full control over which updates and when these updates are pushed to their devices by way of a web interface. Additionally, customers will be able to push their own updates to their devices using the same OTA system. Managing deployed devices is made easy by providing a high-level view of all devices and their current status. Grouping devices together into fleets is supported and makes managing updates for many devices easy. Every device publishes information up to the server which can prove useful for evaluating device health, inconsistencies in deployed devices, etc. Read more

  • YaST Team: Highlights of YaST Development Sprints 88 and 89

    A few weeks ago, we wrote about the new ItemSelector widget that is finding its way into YaST user interfaces. It turned out that just a simple on/off status is not enough in some cases, so we had to extend that concept. For example, software modules may have dependencies, and we want to show the difference between one that was explicitly selected by the user and one that was auto-selected because some other software module requires it. This kind of shook the foundations of the underlying classes; all of a sudden a bit is no longer just a bit, but it needs to be broken down into even smaller pieces. Well, we cheated; we now use integer values instead. Most of the class hierarchy still only uses 0 and 1, but the new YCustomStatusItemSelector also supports using higher numbers for application-defined purposes. For each possible status value, the application defines the name of the icon to be displayed (for graphical UIs like the Qt UI), the text equivalent (for text mode / the NCurses UI), and an optional nextStatus which tells the widget what status to cycle to when the user changes the status of an item with a mouse click or with the keyboard. A value of -1 lets the application handle this. So this is not a one-trick-pony that is useful only for that one use case (the software modules), but a generic tool that might find good uses in other places all over YaST as well.
