  • Why SELinux is inherently complex
    The root of SELinux's problems is that SELinux is a complex security mechanism that is hard to get right. Unfortunately this complexity is not (just) simply an implementation artifact of the current SELinux code; instead, it's inherent in what SELinux is trying to do.
  • SELinux is beyond saving at this point
    SELinux has problems. It has a complexity problem (in that it is quite complex), it has technical problems with important issues like usability and visibility, it has pragmatic problems with getting in the way, and most of all it has a social problem. At this point, I no longer believe that SELinux can be saved and become an important part of the Linux security landscape (at least if Linux remains commonly used). The fundamental reason why SELinux is beyond saving at this point is that after something like a decade of SELinux's toxic mistake, the only people who are left in the SELinux community are the true believers, the people who believe that SELinux is not a sysadmin usability nightmare, that those who disable it are fools, and so on. That your community narrows is what naturally happens when you double down on calling other people things; if people say you are an idiot for questioning the SELinux way, well, you generally leave.
  • Systemd 230 Is Upsetting Some Over Its KillUserProcess Setting
    Systemd 230 was released just last week and it has taken heat not only for opening up FBDEV to potential security issues, which already reverted, but also for changing the default behavior of user processes. Systemd 230 made a change where KillUserProcess defaults to yes. This terminates user processes that are part of the user session scope when the user logs out. This is causing problems for ssh-agent, screen, and other common Linux processes.

  • XnViewMP is a Full-featured Image Manipulation and Batch Converter Tool
    The quality of image and video capture has improved tremendously over the years and the capabilities of our digital devices continue to push the limits of image quality. However, there is a bummer! The high-res images we take does come at the hefty price of an increase in the size of images taken. For this reason, uploading images on the internet can be painfully slow especially if you’re on a network with minimal bandwidth. While there are varying online services and softwares for other platforms that will effectively convert your image files while still maintaining the original quality, it is rather hard to come by native clients for Linux systems.
  • XenServer Dundee Released
    It was a little over a year ago when I introduced a project code named Dundee to this community. In the intervening year, we've had a number pre-release builds; all introducing ever greater capabilities into what I'm now happy to announce as XenServer 7. As you would expect from a major version number, XenServer 7 makes some rather significant strides forward, and defines a significant new capability.
  • Meet Franz – Alles Klar Herr Kommissar?
    I decided to try Franz on Linux, and I chose the somewhat less than obvious CentOS 7 for this task, just to show that it can be done with modernity and delight. The installation package is an archive, which you extract, and then run the Franz binary. That is all. An elegant, somewhat flat and utterly HTML-JS-rich client will launch.
  • Access Blocked Websites In Censored Regions With Lantern
    Lantern is a free, open source internet censorship circumvention software that was created to "give users fast access to the blocked Internet". The application is available for desktops (Linux, Windows, Mac) and Android.
  • MKVToolNix 9.2.0 MKV Manipulation Tool Brings Small Fixes and Improvements
    Moritz Bunkus announced the second major release of his powerful and open source MKV (Matroska) manipulation utility for all supported operating systems, including Linux, Windows, and MacOS. MKVToolNix 9.2.0 comes a little over a month since the release of MKVToolNix 9.1.0, but users should not expect any many new features, as the developer only had time to fix some of the issues that have been reported during this time. There is, however, an important change in the mkvinfo component, but it only affects those who use the software on Microsoft Windows and Mac OS X platforms.
  • RcppArmadillo 0.7.100.3.0
    The first Armadillo release of the 7.* series is out: a new version 7.100.3. We uploaded RcppArmadillo 0.7.100.3.0 to CRAN and Debian. This followed the usual thorough reverse-dependecy checking of by now 230 packages using it.

Leftovers: KDE

  • Plasma Wayland ISO Checkup
    My Plasma Wayland ISOs are building nicely fresh each day. I asked Betty the fuzzy Guinea Pig to gave one a try today and there’s still obvious bugs like no text on task bar and the blue window bars are back but she’s generally impressed at how this is likely to be a good replacement for X in the near future.
  • Call for new KStars splash screen
    KStars gained two seats for Google Summer of Code 2016. The first project is to develop KStars Lite, a small footprint KStars aimed for tablet/mobile and low powered devices. The second project is to port KStars to Windows, including migration of INDI Client library and Ekos. Both projects are progressing along quite nicely and we expect to see stellar results by the end of the summer.

  • KDev-Embedded, The alpha version is coming !
    Today one of the most important steps was performed, the first upload to a microController. The code was a blink compiled with a makefile and uploaded with the KDev-Embedded plugin to an AVR microController (Arduino Nano board).
  • Verdigris: Qt without moc
    Verdigris is a header-only library that can be used with Qt. It uses macros to create a QMetaObject that is binary compatible with Qt's own QMetaObject without requiring moc. In other words, you can use Verdigris macros in your Qt or QML application instead of some of the Qt macros and then you do not need to run moc.

  • Some plans do not cooperate with you…
    I reached the creator at the IRC channel of KDE to see if he could help me, and Jonathan Riddel gives me the help that I need it, at the selection of bugs that I could work and others things that I was thinking about Umbrello. After two days, one before the end of submission time, I submitted my project to the KDE Community.
  • Coding at Lakademy
    Today is the third day that Lakademy is happening at Federal University of State of Rio de Janeiro (UNIRIO), and since the first hour, I’m doing a lot of code. The work is concentrate on my GSoC Project, and finally getting on track on my work in Umbrello.
  • if (LaKademy 2016) goto Rio de Janeiro
    Rio de Janeiro, the “Cidade Maravilhosa”, land of the eternal Summer. The sunlight here is always clear and hot, the sea is refreshing, the sand is comfortable. The people is happy, Rio de Janeiro has good music, food, the craziest parties of the world, and beautiful bodies having fun with beach games (do you know futevolei?).
  • Breeze Dark Color Scheme
    Just as quick info, with the next KDE Frameworks 5 release, namely KF5 version 5.23, the KTextEditor framework gains a Breeze Dark color scheme. The colors mostly stick to the Breeze color palette, with some minor changes, since KTextEditor needs more colors the the color palette itself ships. To use this color scheme, go to the config dialog and choose “Breeze Dark” in the Fonts & Colors config page. We hope this is useful – mandatory screenshot:

  • Yet Another GSoC Blog
    TL;DR: Well Hey there, Chantara here. I will be working with 2 awesome mentors, Stikonas and teo-, to add LVM and hopefully RAID support for KDE Partition Manager and KPMCore library over my summer with Google Summer of Code. If you’re interested, read on!!! :)
  • KDE Partition Manager 2.2.0
    KDE Partition Manager and KPMcore 2.2.0 are now released with a proper LUKS support! This is a fairly big feature release but it also got tested more than usual, so a lot of bugs were fixed (including some crashes). Unfortunately there is still one more reproducible crash (bug 363294) on exit when file open/save dialogs are used (and very similar crashes actually exist in some other KDE programs, e.g. kdebugdialog or Marble). If anybody has any idea how to fix it I would be grateful.

  • The work on animation features continues
    While the first stable Krita version with animation is just around the corner, I am already rolling up my sleeves with plans to take the feature to the next level. It's Google Summer of Code time again. A lot has happened since last year. Import for image sequences was added, the timeline docker was reworked and a large number of smaller changes and fixes were implemented to make the animation tools ready for inclusion in Krita 3.0. For a nice overview, check out GDQuest's video tutorial.
  • Free Software Artists and their Tools — Part I: David Revoy & Krita
    The idea that Free Software has no decent design programs, and that it is impossible to produce quality art without proprietary apps is one of those myths that refuses to die. For quite some time now, OCSmag has been on a mission to prove otherwise. In this latest series we talk to three artists who use Free Software tools to produce their works.
  • Krita at KomMissia
    Last weekend, ace Krita hacker Dmitry Kazakov attended KomMissia, the annual Russian comics festival. Best quote award goes to the Wacom booth attendants, who install Krita on all their demo machines because “too many people keep asking about it”!
  • KStars on Windows – Alpha version
    Using emerge tool, I started to build KStars on Windows. Since this process could be very troublesome, I used a Windows 7 32-bit virtual machine. Actually, for building KDE sources, the KDE developers recommend the 32-bit version of Windows 7.
