KDE: OpenSUSE Leap 15 KDE Edition, Falkon in GSoC, Plasma in Slackware and Future KWin Work

Filed under
KDE
  • What’s New in openSUSE Leap 15 KDE Edition

    openSUSE Leap 15 has been released by OpenSUSE project. This released based on the upcoming SUSE Enterprise Linux 15 series that offers better stability and long-term support, also features updated components and technologies designed for power users.

    Major highlights of the openSUSE Leap 15 operating system include a new partitioner implemented in the installer, integration with the Kopano open-source groupware application suite, Firewalld as the default firewall management tool, a new classic “server” and “transactional server” system roles with read-only root filesystem and transactional updates, cloud optimizations, and a brand-new look that’s been closely aligned with SUSE Linux Enterprise.

  • [Falkon] Fifth week of coding phase, GSoC'18

    The week was totally involved in developing the GUI for QML Plugins.

    [...]

    Everything is fine upto this until I found that this didn't worked. My Mentor (David Rosca) explained that this is because the QWindow is not grabing mouse and keyboard events - which means that the window is not activated - so I added QWindow::requestActivate and It works like a charm!

  • [Slackware] Ktown in June ’18 – Plasma 5.13 in the ‘testing’ repo

    It’s that time of the month again. KDE tarballs have all been refreshed, and so this presents the opportunity to release a new package set for the Plasma 5 Desktop Environment… but then I found out that the new Plasma 5.13 depends on a minimum Qt5 version number of 5.10. Currently I have Qt 5.9.5 in my repository, and this is a LTS release (Long Term Support). The next LTS release will be 5.12 and this will not be available before end of 2018. Also, the current Plasma 5.12 has Long Term Support and the new Plasma 5.13 has not.

  • It’s not a good bye

    As you might have heard I decided to step down from my maintainer positions in KDE, especially KWin. Unfortunately I had to read very weird things about it and so I think it’s time to write about what it means that I am no longer maintainer of KWin.

    First of all: I’m not leaving KDE. I’m still contributing in form of code, bug management and reviews. And I intend to continue to do this.

    Second of all: I did not step down as maintainer because of the VDG or the usability group. I understand that my mail read like this, but it’s not the case. That I would step down as maintainer was inevitable and I’m sure it didn’t come as a general surprise to my fellow Plasma and KWin hackers. Personally I decided to step down as maintainer once the Wayland port is finished years ago. In my opinion KWin reached that state about two years ago. I continued to be maintainer to prepare for a good hand over. I deliberately reduced my involvement and passed responsibility to others. This was a long process and worked great in my opinion. As an example I want to point out the new and awesome blur effect introduced in 5.13. My first comment on the phabricator code review was that I’m not going to review it, but leave it to others. I think the result is great and I’m very happy how this worked out.

  • Linux Accra: A haven for open source software enthusiasts

    If you’re a community-minded software enthusiast with some free time on Saturday afternoons then, the Linux Accra Users Group (LAUG) is probably the most important institution you may be hearing about only now.

    Consisting of open source and Linux hobbyists, professionals, enthusiasts, developers, as well as newbies, LAUG members meet over their shared interest in Linux and other software—to undertake related projects as well as offer assistance and resources to individual members’ projects.

  • SouthEast LinuxFest 2018 Recap

    SouthEast LinuxFest (SELF) just wrapped up, and we had a great time getting to visit with our friends on the East Coast. We had a steady stream of people stop by our booth to tell us how much they enjoy using FreeNAS. We answered questions about what’s new in FreeNAS, iXsystems storage solutions, and Project Trident (a new Open Source project focusing on BSD desktop development). TrueOS and Lumina Desktop also sparked the interest of many SELF attendees. A demo system was on display to showcase the current state of the Open Source projects we support and to emphasize the differences between FreeBSD-based projects and standard Linux Distributions.

  • BSDCan 2018 Recap

    BSDCan is special for starting at connecting airports around the world and ending informally at cafes around ByWard Market in Ottawa. Celebrating its 15th year, BSDCan 2018 tied with BSDCan 2015 for the record number of attendees at 280. This made for a busy, but never crowded, event where the hallway track is always just as important as the sessions tracks. Choosing which concurrent sessions to miss and deciding where to eat are probably the two most difficult decisions that BSDCan attendees face.

  • Vendors, Disclosure, and a bit of WebUSB Madness

    Was there any specific bug to report before we gave the talk? No, because it was widely discussed in the security scene that WebUSB is a bad idea. We believe we have demonstrated that by showing how it breaks U2F. There was no single issue to report to Google or Yubico, but a public discussion to trigger so WebUSB is fixed.

    [...]

    I do not know what “private outreach” means and why Yubico lied about being unable to replicate our findings in a call on March 2nd, even though they had it apparently working internally.

    “I just wanted to change the conversation I was having with all my neighbors who were like, ‘Ugh, computers are hard, what can you do?’ to ‘Hey, here are some things you can do’,” she said. “A lot of people don’t feel they have agency around privacy and technology in general. This case was about having your own agency when companies don’t behave how they’re supposed to with our private information.”

You may think it's still Saturday for me, and that I should give you
one more day of merge window to send in some last-minute pull
requests, but I know better. I'm in Japan, and it's Sunday here. Plus
I hope to spend much of this Sunday on a boat (assuming the swells
allow it), so I'm closing the merge window early morning rather than
in the afternoon.

So here we are - no more merge window, so please don't even try to
send me updates any more. Just fixes, please.

Gnome 3.28 review - Minimalism gone wrong

Filed under
GNOME
Reviews

Gnome 3.28 brings in a few interesting changes to the Gnome table - not too many, though, this version isn't a radical revamp, more sort of a gradual progression of the basic idea behind the Gnome desktop environment. Not bad in that regard. Bad in every other regard.

Unfortunately - and this is nothing personal, all I care for is to be happy and productive with my desktops, and Gnome 2 was my favorite thing for years and years - Gnome 3.28 is a sterile, counterproductive pseudo-touch concept that serves little purpose on the desktop. It requires significant tweaking and immense changes under the hood to make presentable and usable, and even then, it works hard against the user. Performance is really bad, a decade-old laptop with anything other than Gnome works better than a contemporary model with Gnome, and you feel the sluggishness with every little thing you do. It's life-sapping. The more you multi-task the worse it gets.

All in all, Gnome 3.28 has changed little from the original Gnome 3 a few years ago. It is still not suited for purpose, it has not evolved in any way, and in fact, there are fresh new functional regressions in the product. It's getting more and more difficult to achieve simple things, and you're fighting against the desktop. Not how it's meant to be. Maybe Linux will make it big on the phone and tablet one day, and then Gnome could be a blast. But on traditional computing devices, it's a flop. Not recommended, I'm afraid. Take care.

Canonical Releases Ubuntu 18.04 LTS Kernel Security Update for Raspberry Pi 2

Filed under
Linux
Ubuntu

Earlier this week, Canonical released an important kernel security update for Ubuntu 18.04 LTS, as well as other supported Ubuntu releases like Ubuntu 17.10, Ubuntu 16.04 LTS, and Ubuntu 14.04 LTS, to address various vulnerabilities affecting the kernel packages for 64-bit machines, Amazon Web Services (AWS) and Google Cloud Platform (GCP) systems, and cloud environments.

Now, the same kernel patch that was made available for Ubuntu 18.04 LTS users on 64-bit, AWS, GCP, and cloud environments is now available for Raspberry Pi 2 devices too, fixing an issue (CVE-2018-1092) in Linux kernel's EXT4 file system implementation discovered by Wen Xu, which could allow an attacker to crash the affected system by mounting a specially crafted EXT4 file system.

GitHub as the Latest Example of Microsoft Entryism in Free/Libre Software

Filed under
Just talk

"This is in effect the very same trick they did/pulled with Novell and SUSE (where Nat Friedman came from after his Microsoft internship) about a decade ago."

Postman

THE recent GitHub takeover, which has not formally been approved just yet (although there are no foreseen barriers to it), is definitely bad news; it is a lot of things to Microsoft however. It is good news only to Microsoft and GitHub shareholders, who basically sold out many developers without rewarding/compensating them for this unwanted (to them) takeover.

There are many aspects to it: First of all, it helps paint Microsoft as "open source" and it helps Microsoft gain leverage over developers, e.g. their choice process of framework/s and licence/s (Microsoft still dislikes copyleft); by leverage over platform they can suggest Azure, for example, or create bindings to it; they gain leverage over projects tied to governments, including some of our clients at work; Microsoft can vainly tell them, i.e. the governments and their developers: "look, you want FOSS? We're FOSS" (so they effectively become their own competitor!). In fact, there's so much more and I could easily name a couple dozen examples, but I know people pursue/need concision here. For an analogy, in politics this concept or strategy is known as "entrism" or "entryism".

Microsoft also uses patents to blackmail FOSS; there's that element too, albeit many people conveniently choose to forget it. Microsoft is sending patents to patent trolls, then offers "Azure IP Advantage". This is in effect the very same trick they did/pulled with Novell and SUSE (where Nat Friedman came from after his Microsoft internship) about a decade ago.

There are many other angles to it, including programming languages, frameworks (e.g. proprietary IDEs like MSVS), code editors and not just bindings to Microsoft as a host and API provider. People, especially developers of software, generally know how E.E.E. works; the basic precondition/premise is that you gain controls/leverage over that which threatens you (Nokia: Elop, Novell: Mono and lots more examples). So that's kind of a way of getting inside, gradually forming a partnership and then shutting down or sidelining whatever threatens you. Like Xamarin did to RoboVM, in effect killing it under Friedman's leadership. Friedman is going to be the chief of GitHub.

Microsoft can direct the opposition's decisions and its fate. Sadly, they already do this inside the Linux Foundation, where Microsoft staff already has chairs in the Board.

From what I can gather, developers ditching GitHub is becoming a fairy common thing this month. I already see the 1) active 2) large 3) non-Windows ones leaving, but it can take time; some told me they still rely on open bug reports and other 'vendor lockin'; that needs some work before they can migrate; the real alternative is self-hosted git.

  • GSoC 2018 - First month status

    Hi all, I am Chinmoy and I am working on the GSoC project Verifying signatures of pdf files. This is my very first post and in this I intend to inform about the progress I have made since May 14.

    Now due to some unforeseen problems I had to deviate from my proposed timeline. Initially my plan was to implement all non-graphical components in the first half of coding period and in the later half implement the graphical components. But while coding RevisionManager (this would have enabled to view a signed version of document before an incremental update like Adobe Reader does) I ran into some issues while designing its API. So I postponed my work on RevisionManager and started working on the graphical components. So as a result I was able to add basic GUI support needed to verify signed PDF. The patches are listed in T8704.

  • How to Enable the Blur Effect in KDE Plasma 5.13

    The new blur effect in KDE Plasma 5.13 is wowing a lot of people, us included, but a few of you have been in touch to ask how you can enable or configure the blur on your own system.

    Plasma 5.13 should (as I understand it) come with the swish new gaussian blur effect enabled by default provided you use the Breeze theme. Provided you’re on a Linux distro that has the latest Plasma release (like KDE Neon) you should see it.

    If you don’t have it, or if you want to adjust the blur strength and opacity, read on. In this post, we’ll show you what you need to do to get it working.

  • In Defense Of Ubisoft: Crowdsourcing Game Content Creation Is Actually Fun And Non-Exploitive

    Crowdsourcing has obviously now been a thing for some time. Along internet timelines, in fact, crowdsourcing is now something close to a mature business practice and it's used for all manner of things, from the payment for goods created, to serving as a form of market research for new products and services, all the way up to and including getting fans involved in the creation and shaping of an end product. The video game industry was naturally an early adopter of this business model, given how well-suited the industry is to technological innovation. Here too we have seen a range of crowdsourcing efforts, from funding game creation through platforms like Kickstarter to empowering supporters to shape the development of the game.

    [...]

    I'll end this with a thought experiment. Imagine for a moment if I had written this same post, except I did a find/replace for "Ubisoft" and replaced it with "Sole game creator." Does anyone really think the same level of outrage would exist? If not, then this isn't a moral question at all, but a monetary one. And if that's the case, it should go without saying that Ubisoft's reputation shouldn't prevent it from being able to try something good and cool with its fans.

“Respects Your Freedom” (RYF) and Purism's Librem 5

  • Purism's Librem 5 To Rely On Secondary Processor For Binary Blobs
    With not being able to deliver a 100% fully free software / libre system, the Librem 5 smartphone will rely upon a secondary processor for dealing with the necessary binary blobs for hardware initialization to keep them out of touch from the U-Boot boot-loader and Linux kernel. The first road-block in their effort to make the Librem 5 smartphone as open as possible is the DDR PHY with firmware blobs needed for the DDR4 memory training process at boot time. With it not being realistic for them to rewrite the firmware blob to do the DDR4 PHY training, they are planning to punt the binary-only blobs out to a secondary processor. In doing so, they can also apply for an exclusion with the Free Software Foundation for still having a device that "Respects Your Freedom" while still having necessary binary blobs at play.

    Larry Trowell, principal consultant with Synopsys Software Integrity Group, said the government shares some of the blame for the NSA exploit. "It's in every country's interest to develop systems enabling offensive and defensive strategies to protect individuals and national services," Trowell wrote via email. "There is no fault in that. If the NSA does have some blame to share in this situation, it is for allowing secrets to be exfiltrated -- not in developing them." Jett said although the NSA exploit was stolen, "they didn't create the vulnerabilities that allow for the malware to exploit devices." "As such, you can't hold them responsible for the malware that has emerged from the EternalRomance exploit. Vendors whose products are vulnerable to EternalRomance are responsible for resolving the exploit problem," Jett wrote. "Additionally, it has been more than a year since the NSA exploits were released, and vendors have created patches. It becomes incumbent on the users to make sure they are properly patching their software and reducing the threat surface for these exploits."
