Krita 4.2.8 Beta

Filed under

We had to skip the October release because we were working on a bunch of issues that took longer to resolve than planned, but that means that this release has more fixes than ever. Please test this beta, and take the survey afterwards!

There has been a lot of work on vector shapes, the transform tool and, especially, saving on Windows. Windows usually only writes out saved files to the actual disk when it feels like it.

So if you’d cut the power to your computer before Windows did that, you might get corrupted files. With 1,500,000 distinct Windows 10 users of Kritain the past month, chances are good for that happening (just like there are people who work exclusively with unnamed autosave files — don’t do that!), so we now try to force Windows to write files to disk after saving.

How is User Support in Krita organized?

  • How is User Support in Krita organized?

    Some of our users seem to don’t really know how Krita (as a project) functions or not understand how User Support is done (User Support: helping users, solving their problems with Krita, hardware, use-cases, limitations of tools, misunderstanding on how some features work). That’s natural – nobody knows details before they get inside and can see for themselves.

    I did get inside and I’m tempted to write that the answer to the question in the title is “Not at all”, but that’s not actually true – often you’ll get the first answer on within a few hours. On the other hand, the person answering you will most probably be me…

    When I first came to, a lot of questions were left unanswered, and most of the others had an answer from Boudewijn Rempt: the lead developer. I thought that I’d prefer Krita’s main developer to develop, not answer user questions. I knew that helping Krita on the code side would be difficult because of the complexity of the code and me having little time between uni and writing my thesis, so I decided to help with user support which I could easily do in small chunks of free time. A year later, when I was hired to actually hack on Krita, I realized that now there is, again, a full-time Krita developer doing user support…

Events: KVM Forum 2019 and "Bar Charts for Diversity"

  • A recap of KVM Forum 2019

    The 13th KVM Forum virtualization conference took place in Lyon, France in October 2019. One might think that development may have finished on the Kernel Virtual Machine (KVM) module that was merged in Linux 2.6.20 in 2007, but this year's conference underscored the amount of work still being done, particularly on side-channel attack mitigation, I/O device assignment with VFIO and mdev, footprint reduction with micro virtual machines (VMs), and with the ability to run VMs nested within VMs. Many talks also involved the virtual machine monitor (VMM) user-space programs that use the KVM kernel module—of which QEMU is the most widely used.

  • Enhancing KVM for guest protection and security

    A key tenet in KVM is to reuse as much Linux infrastructure as possible and focus specifically on processor virtualization. Back in 2007, this meant a smaller code base and less friction with the other kernel subsystems, especially when compared with other virtualization technologies such as Xen. This led to KVM being merged into the mainline with relative ease. But now, in the era of microarchitectural vulnerabilities, the priorities have shifted, and the KVM's reliance on other kernel subsystems can be a liability. For one thing, the host kernel widens the TCB (Trusted Computing Base) and makes for a larger attack surface. In addition, kernel data structures such as the direct memory map give Linux access to guest memory even when it is not strictly necessary and make it impossible to fully enforce the principle of least privilege. In his talk "Enhancing KVM for Guest Protection and Security" (slides [PDF]) presented at KVM Forum 2019, long-time KVM contributor Jun Nakajima explained this risk and suggested some strategies to mitigate it.

  • Bar charts for diversity

    At the Linux App Summit I gave an unconference talk titles Hey guys, this conference is for everyone. The “hey guys” part refers to excluding people from a talk or making them feel uncomfortable – you can do this unintentionally, and the take-away of the talk was that you, (yes, you) can be better. I illustrated this mostly with conversational distance, a favorite topic of mine that I can demonstrate easily on stage. There’s a lot of diversity in how far people stand away from strangers, while explaining something they care about. The talk wasn’t recorded, but I’ve put the slides up. Another side of diversity can be dealt with by statistics. Since I’m a mathematician, I have a big jar of peanuts and raisins in the kitchen. Late at night I head down to the kitchen and grab ten items from the jar. Darn, all of them are raisins. What are the odds!? Well, a lot depends on whether there are any peanuts in the jar at all; what percentage is peanuts; whether I’m actually picking things randomly or not. There’s a convenient tool that Katarina Behrens pointed me to, which can help figure this out. Even if there’s only a tiny fraction of peanuts in the jar, there’s an appreciable chance of getting one (e.g. change the percentage on that page to 5% and you’ll see).

Linux on the MAG1 8.9 inch mini-laptop (Ubuntu and Fedora)

The Magic Ben MAG1 mini-laptop is a 1.5 pound notebook computer that measures about 8.2″ x 5.8″ x 0.7″ and which features an 8.9 inch touchscreen display and an Intel Core m3-8100Y processor. As I noted in my MAG1 review, the little computer also has one of the best keyboards I’ve used on a laptop this small and a tiny, but responsive trackpad below the backlit keyboard. Available from GeekBuying for $630 and up, the MAG1 ships with Windows 10, but it’s also one of the most Linux-friendly mini-laptops I’ve tested to date. [...] I did not install either operating system to local storage, so I cannot comment on sleep, battery life, fingerprint authentication, or other features that you’d only be able to truly test by fully installing Ubuntu, Fedora, or another GNU/Linux-based operating system. But running from a liveUSB is a good way to kick the tires and see if there are any obvious pain points before installing an operating system, and for the most part the two operating systems I tested look good to go. Booting from a flash drive is also pretty easy. Once you’ve prepared a bootable drive using Rufus, UNetbootin, or a similar tool, just plug it into the computer’s USB port, hit the Esc key during startup to bring up the UEFI/SETUP utility.
