How Minecraft got me involved in the open source community

Monday 10th of October 2016 07:01:00 AM

When people first think of "open source," their mind probably first goes to code—something technical that requires an intermediate understanding of computers or programming languages. But open source is a broad concept that goes beyond binary bits and bytes. Open source projects hold great regard for community participation. The community is a fundamental piece of a successful open source project. For my experience getting involved with open source, I began in the community and worked my way around from there.

Tips for building your own maker workspace

Friday 7th of October 2016 07:02:00 AM

I firmly believe that in the absence of any intentional organizational strategy a person's workspace becomes a reflection of their mind. Like bits of knowledge stored in the brain, tools and assets instinctively find themselves organized in a way that feels right to the individual.

Why public libraries need to support open source

Friday 7th of October 2016 07:00:00 AM

People turn to public libraries for answers, and a lot of times libraries are superb at providing them. But when it comes to providing answers about open source, libraries have an uneven track record.

What can we do to make this better so that more people can turn to their public library to learn about open source software, hardware, and principles?

4 open source alternatives for Google Calendar

Thursday 6th of October 2016 07:03:00 AM

For many of us, our calendar is our lifeblood. Without it, we would be lost, perhaps both literally and figuratively.

While some people can get away with a wall calendar or a paper day planner to organize their schedule, a whole lot of us have turned over the process of managing time allotments to a digital calendar. In truth, most of us are juggling quite a few calendars from both our work and personal lives, and often a few other organizations that we're involved with, including anything from non-profits to tech meetups to social clubs.

How open source is enabling the digital art age

Thursday 6th of October 2016 07:02:00 AM

When I was in college, software development seemed much more difficult. I went to school for electrical engineering, so many of the courses dealt with programming tiny computers in assembly language. There were complicated toolchains, expensive compilers, and thousand-page manuals that described how to set the registers so that these chips would even operate.

Linux is a new frontier for young developer

Thursday 6th of October 2016 07:01:00 AM

When I was 17 years old, I started using Linux because I wanted a desktop that resembled my brother-in-law's Gentoo laptop, which used the KDE environment. Instead, I got the now-nostalgic brown and orange GNOME 2 environment because I'd installed Ubuntu. (Ubuntu has since changed its color palette.)

A guide to building trust in teams and organizations

Thursday 6th of October 2016 07:00:00 AM

My travels globally have given me a feeling for how best to work in many different contexts—like Latin America, West Africa, North Africa, and Southeast Asia, to name a few. And I've found that I can more easily adapt my work style in these countries if I focus on something that plays a role in all of them: trust.

How to champion your committers

Wednesday 5th of October 2016 07:02:00 AM

A number of companies today proudly wear the open source badge to show their dedication to various projects, particular communities, or simply the idea of free software licensing. Many have gone down the Red Hat business route, creating a revenue model based on support and services, while others have built their business around proprietary features and add-ons to open source projects.

Business models vary, but what all successful open source companies have in common is the ability to maintain healthy relationships.

Avoiding quality assurance disasters with openQA

Tuesday 4th of October 2016 07:02:00 AM

Proper quality assurance can save lives and money. (Anyone remember the Ariane 5 explosion in 1996?) That's why the openSUSE and Fedora communities heavily rely on openQA, a fully automated and open source test framework. OpenQA is primarily used to test different Linux distributions, but applications can also be installed on top of it to test desktop environments like GNOME and KDE.

How to prevent coworker competition from ruining company culture

Tuesday 4th of October 2016 07:00:00 AM

During the humid summer months of 1954, twenty-two 11 and 12-year-old boys were randomly split into two groups and taken to a 200-acre Boy Scouts of America camp in Robbers Cave State Park, Oklahoma.

Over the next few weeks, they would unknowingly be the subjects of one of the most widely known psychological studies of our time. And the ways these groups bonded and interacted with each other draw some interesting parallels to our understanding of workplace culture.

Leftovers: Software

  • i2pd 2.10 released
    i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client. I2P (Invisible Internet Protocol) is a universal anonymous network layer. All communications over I2P are anonymous and end-to-end encrypted, participants don't reveal their real IP addresses. I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers). I2P allows people from all around the world to communicate and share information without restrictions.
  • Pixeluvo Review | Photo Editor for Linux & Windows
    A review of Pixeluvo, a great photo editor available on Linux and Windows. Pixeluvo is not free or open source.
  • Blit, A Retrospective On My Largest Project Ever
    I’ve always been someone who’s liked art and programming. Especially combining the two. One of my favorite genres is pixel art, or sprites as they are also known. I’ve dabbled in making a few other art programs before, but nothing like this. Originally Blit supposed to be only a sprite animation tool that had a modern look and feel, but my ideas for it grew greater (*sigh* feature creep). There are many other sprinting tools out there like GrafX2, Aseprite, (and other 2D animation programs like TVPaint). I’m not saying that it’s wrong that they make their own GUI toolkit, but it feels kind of odd. I really wanted to bring these types of programs out of the days of the Amiga. After doing some initial research, I settled on using Qt.

  • FunYahoo++: New Yahoo Messenger Plugin For Pidgin / libpurple [PPA]
    Yahoo retired its old Messenger protocol in favor of a new one, breaking compatibility with third-party applications, such as Pidgin, Empathy, and so on. Eion Robb, the SkypeWeb and Hangouts developer, has created a replacement Yahoo prpl plugin, called FunYahoo++, that works with the new Yahoo Messenger protocol. Note that I tested the plugin with Pidgin, but it should work with other instant messaging applications that support libpurple, like BitlBee or Empathy.

    The latest GCC 7 development code has an optimization pass now for loop splitting.
  • GCC 7 To End Feature Development Next Month
    Friday's GCC 7 status report indicates the feature freeze is coming up in just a few weeks. Red Hat developer Jakub Jelinek wrote in the latest status report, "Trunk which will eventually become GCC 7 is still in Stage 1 but its end is near and we are planning to transition into Stage 3 starting Nov 13th end of day time zone of your choice. This means it is time to get things you want to have in GCC 7 finalized and reviewed. As usual there may be exceptions to late reviewed features but don't count on that. Likewise target specific features can sneak in during Stage 3 if maintainers ok them."
  • GNU Parallel 20161022 ('Matthew') released [stable]
    GNU Parallel 20161022 ('Matthew') [stable] has been released. It is available for download at: No new functionality was introduced so this is a good candidate for a stable release.

    I am pleased to announce the release of guile-ncurses 2.0 guile-ncurses is a library for the creation of text user interfaces in the GNU Guile dialect of the Scheme programming language. It is a wrapper to the ncurses TUI library. It contains some basic text display and keyboard and mouse input functionality, as well as a menu widget and a form widget. It also has lower level terminfo and termios functionality.
  • Unifont 9.0.03 Released
    Unifont 9.0.03 is released. The main changes are the addition of the Pikto and Tonal ConScript Unicode Registry scripts.
  • PATHspider 1.0.0 released!
    In today’s Internet we see an increasing deployment of middleboxes. While middleboxes provide in-network functionality that is necessary to keep networks manageable and economically viable, any packet mangling — whether essential for the needed functionality or accidental as an unwanted side effect — makes it more and more difficult to deploy new protocols or extensions of existing protocols. For the evolution of the protocol stack, it is important to know which network impairments exist and potentially need to be worked around. While classical network measurement tools are often focused on absolute performance values, PATHspider performs A/B testing between two different protocols or different protocol extensions to perform controlled experiments of protocol-dependent connectivity problems as well as differential treatment.

Leftovers: KDE

  • Happy 20th birthday, KDE!
    KDE turned twenty recently, which seems significant in a world that seems to change so fast. Yet somehow we stay relevant, and excited to continue to build a better future. Lydia asked recently on the KDE-Community list what we were most proud of.
  • SETI – Week of Information Technology
  • KDevelop for Windows available on Chocolatey now
    Which is already great in itself! But now it's also possible to install it via the super popular Windows package manager for Windows, Chocolatey.
  • colord-kde 0.5.0 released!
    Last official stable release was done more than 3 years ago, it was based on Qt/KDE 4 tech, after that a few fixes got in what would be 0.4.0 but as I needed to change my priorities it was never released. Thanks to Lukáš Tinkl it was ported to KF5, on his port he increased the version number to 0.5.0, still without a proper release distros rely on a git checkout.
  • Call for attendees Lakademy 2017
    As many of you know, since 2012 we organize the Lakademy, a sort of Latin American Akademy. The event brings together KDE Latin American contributors in hacking sessions to work on their projects, promo meetings to think KDE dissemination strategies in the region and other activities.
  • Plasma 5 Desktop on FreeBSD Branding
    The FreeBSD packages of KDE software — the KDE 4 desktop, and soon KDE Frameworks 5 and Plasma 5 Desktop and KDE Applications — have traditionally been shipped pretty much as delivered from the upstream source. We compile, we package, and there is very little customization we do as a “distro”. The KDE 4 packages came with a default wallpaper that was a smidgen different from the one shipped with several Linux distro’s. I think Ivan Cukic did that artwork originally. For Plasma 5 Desktop, we also wanted to do a tiny bit of branding — just the default wallpaper for new users, mind.
  • A bit on Tooling
    So on the weekend I also worked on updating Qt 5.6.1 to Qt 5.6.2 on FreeBSD, which involves using new and scary tools as well. Power tools, they can be really useful, or they can take off a finger if you’re not careful. In this case it was Phabricator, which is also used in KDE — but not everywhere in KDE. For FreeBSD, the tool is used to review updates to ports (the packaging instructions), so I did an update of Qt from 5.6.1 to 5.6.2 and we handled the review through FreeBSD’s Phab. The ports infrastructure is stored in SVN, so the review is relatively straightforward: update the ports-tree checkout, apply your changes, use arc to create or update a review request. I was amazed by how painless it was — somehow I’d been frightened. Using the tool once, properly, makes a big difference in self-confidence.
  • Krita 3.1 second beta.
    The Krita 3.1 beta come with a full features and fixes. The linux version to download your krita-3.0.91-x86_64.appimage.
  • Second Beta for Krita 3.1 Available
    We’re still fixing bugs like madmen… And working on some cool new features as well, but that’s for a later release. In any case, here is the second Krita 3.1 beta! Yes, you’re reading that correctly. Originally, we had planned to use 3.0.2 as the version for this release, but there is so much news in it that it merits a bigger version bump.


  • Consequences of the HACK CAMP 2016 FEDORA + GNOME
    I used to do install parties in order to promote the use of FEDORA and GNOME project since five years ago. As you can see more details in the Release Party FEDORA 17 for Fedora, and Linux Camp 2012, GNOME PERU 2013, GNOME PERU 2014...
  • GNOME Shell Making It Easy To Launch Apps/Games For Optimus / Dual GPU Systems
    With the GNOME 3.24 desktop that's currently in development the latest GNOME Shell code has support for easily letting the user launch an app on a dedicated GPU when applicable for handling NVIDIA Optimus use-cases of having integrated and discrete GPU laptops. When a dual-GPU system is detected, a menu item will be added to opt for "Launch using Dedicated Graphics Card", per this commit. The GNOME Shell change for supporting discrete GPUs was made and when the user opts to launch on the dedicated GPU, the DRI_PRIME=1 environment variable will automatically be set for that new program/game.
