KDE: Linux App Summit 2019, Okular and Krita

  • Bring the Linux App Summit 2019 home

    The GNOME and KDE communities are looking for locations for the Linux App Summit (LAS) 2019, an event that will be held sometime between September and December 2019.

    The Linux App Summit is an evolution of the Libre Application Summit and has a specific focus on the creation of applications that target Linux devices. By co-hosting the conference, KDE and GNOME want to create a space for a more widespread collaboration and work towards a common goal: make the Linux application ecosystem flourish.

    If you are interested in hosting LAS 2019 in your town, send us an e-mail to appsummit@lists.freedesktop.org by May 15th with your proposed location. This will allow the organizing committee to establish contact with you and give you assistance as you put together a bid later on.

  • Rajeesh K Nambiar: Okular: improved PDF annotation tool

    Okular, KDE’s document viewer has very good support for annotating/reviewing/commenting documents. Okular supports a wide variety of annotation tools out-of-the-box (enable the ‘Review’ tool [F6] and see for yourself) and even more can be configured (such as the ‘Strikeout’ tool) — right click on the annotation tool bar and click ‘Configure Annotations’.

    One of the annotation tools me and my colleagues frequently wanted to use is a line with arrow to mark an indent. Many PDF annotating software have this tool, but Okular was lacking it.

    So a couple of weeks ago I started looking into the source code of okular and poppler (which is the PDF library used by Okular) and noticed that both of them already has support for the ‘Line Ending Style’ for the ‘Straight Line’ annotation tool (internally called the TermStyle). Skimming through the source code for a few hours and adding a few hooks in the code, I could add an option to configure the line ending style for ‘Straight Line’ annotation tool. Many line end styles are provided out of the box, such as open and closed arrows, circle, diamond etc.

  • Summer is coming...

    All of this began here, probably this was the first day I was giving Krita a try cause this was the closest I got to Photoshop after switching to Linux. It has been something on and off from that day, sometimes I used Krita, sometimes I mixed it up with GIMP and Inkscape too for satisfying my needs to replace the “Photoshop through Wine”.

    Until 2017 I was just a Krita user, but after installing Gentoo and getting comfortable with compiling programs on my own, I decided to contribute to Krita, cause it feels awesome when your work is being used by millions of people, right?

    So I headed over to their IRC channel, introduced me and told them my intentions, luckily, Scott was there to help me with the things I would love to work on and in a couple of days, I made my first patch to the new Text Tool. Cool, sounds perfect, except it wasn’t cause, that branch which I committed into will probably never get merged into master, why? why? (read them quickly one after another) For the reason that, I immediately left working on that part (even though I promised that I would work) after the first commit, god knows what I was thinking, such an idiot I was.

  • Audio Component Support Being Worked On For The Radeon & Nouveau Drivers

    Linux sound maintainer Takashi Iwai of SUSE has posted a set of patches implementing HD audio component notifier support for the Radeon and Nouveau DRM kernel drivers. Audio component notifier support may not seem like much to get excited about but it allows for more reliable audio hotplug notifications and ELD (EDID Like Data) transfer without accessing the HD audio bus. This yields efficiency benefits and can function without waking up the run-time power management hardware.

  • How to reinstall Linux

    The time has come when you need to wipe your machine and reinstall the operating system so that it is like brand new. However, you don't know what to do and you don't know where to turn. TechRadar has you covered ... even those of you who use Linux! Now, if you're my father, you would delete everything and complain about stuff missing later. In order to be smart about this procedure, it is very wise to do a backup of your computer with all of your files. We have reviewed some great backup solutions from the Toshiba 3TB Cavio, the Western Digital DL4100, to the SanDisk Connect Wireless Flash Drive. You will want to back up your files so that this process is easy. Assuming that is all done, I am going to walk you through each step and what you need to prep.

  • Srestha Srivastava: Google Summer of Code 2019 Update

    I then checked if we were able to get the script and command line for installing these Operating Systems, we can get the script list for an OS, and then choose one using get_nth(), we also needed installation configuration to generate command line from this script, I used default unattended configuration and printed the generated command line on terminal. After having a discussion with my mentor, we split the work further into steps and he created issues for every task on my development branch. First, I created a new class Installer from which the already existing class InstallerMedia will inherit and also the new InstallerTree class which we would need for tree based installations. I realised how important it is to write clear commit messages at every step, especially when your code might be read by many other people, I once included a lot of things in one commit, hence, had to undo it and do it in smaller and cleaner commits. Until now, GNOME Boxes was performing express installations using ISO of the Operating System, so we would extract the kernel and initrd from the downloaded ISO, we had a helper class ISOExtractor, that would help in extracting the kernel and initrd from an ISO file using the ArchiveReader and ArchiveWriter class, but now for tree based installations, we will need to download the kernel and initrd from a https location, so I have created a TreeExtractor class that takes the help of Downloader class, the same class that we use to download ISOs for an Operating System. Hence, now there is an Extractor class from which TreeExtractor and ISOExtractor class inherit.

  • ProFTPD Vulnerability Lets Users Copy Files Without Permission [Ed: Troll site BleepingComputer changed headline from "ProFTPD Remote Code Execution Bug Exposes Over 1 Million Servers" to "ProFTPD Vulnerability Lets Users Copy Files Without Permission" (under rare conditions) because that's too much FUD even by its own standards?]

    Under certain conditions, ProFTPD servers are vulnerable to remote code execution and information disclosure attacks after successful exploitation of an arbitrary file copy vulnerability in the mod_copy module. ProFTPd is an open-source and cross-platform FTP server with support for most UNIX-like systems and Windows, and one of the most popular ones targeting the UNIX-based platforms along with Pure-FTPd and vsftpd.

  • Lyft releases open source data set for autonomous vehicle development

    In an effort to bolster the development of cars capable of driving themselves around without human supervision, Lyft today released an autonomous vehicle data set that the company is calling the largest of its kind. It’s freely available in the existing nuScenes format, which was initially developed by Aptiv. “Autonomous vehicles are expected to dramatically redefine the future of transportation.
