  • Join GNU Guix through Outreachy

    We are happy to announce that for the second time this year, GNU Guix offers a three-month internship through Outreachy, the inclusion program for groups traditionally underrepresented in free software and tech.

  • Functional programming in Python: Immutable data structures

    In this two-part series, I will discuss how to import ideas from the functional programming methodology into Python in order to have the best of both worlds.

    This first post will explore how immutable data structures can help. The second part will explore higher-level functional programming concepts in Python using the toolz library.

  • Kiwi TCMS 6.0

    This release removes squashed migrations. Direct upgrades from versions < 5.3.1 to 6.0 will break without an intermediate upgrade to 5.3.1!

  • littler 0.3.5: Other kids broke my toys

    The sixth release of littler as a CRAN package is now available, following in the now more than twelve-year history as a package started by Jeff in 2006, and joined by me a few weeks later.

    littler is the first command-line interface for R and predates Rscript. And it is (in my very biased eyes) better as it allows for piping as well shebang scripting via #!, uses command-line arguments more consistently and still starts faster. It also always loaded the methods package which Rscript converted to rather recently.

    littler lives on Linux and Unix, has its difficulties on macOS due to yet-another-braindeadedness there (who ever thought case-insensitive filesystems as a default where a good idea?) and simply does not exist on Windows (yet – the build system could be extended – see RInside for an existence proof, and volunteers are welcome!).

piwheels: Speedy Python package installation for the Raspberry Pi

One of the great things about the Python programming language is PyPI, the Python Package Index, where third-party libraries are hosted, available for anyone to install and gain access to pre-existing functionality without starting from scratch. These libraries are handy utilities, written by members of the community, that aren't found within the Python standard library. But they work in much the same way—you import them into your code and have access to functions and classes you didn't write yourself. Read more

KDE: digiKam Recipes, Krita and Calligra Boost From Handshake Foundation

  • digiKam Recipes 18.10.15 Released
    It’s time for another digiKam Recipes update. The most visible change in this update is the new book cover. All screenshots were also updated to reflect changes in the current version of digiKam.
  • [Krita] Interview with Sira Argia
    2014 is the year that I first started to try Linux on my laptop, and then I knew that Windows programs don’t run perfectly on Linux even using “wine”. My curiosity about Linux and the alternative programs led me to Krita. The more time I spent with Linux, the more I fell in love with it. And finally I thought that “I’ll choose Linux as a single OS on my laptop and Krita as a digital painting program for work someday after I get my first graphic tablet.”
  • And so the [Krita] Fundraiser Ends
    Yesterday was the last day of the developers sprint^Wmarathon, and the last day of the fundraiser. We’re all good and knackered here, but the fundraiser ended at a very respectable 26,426 euros! That’s really awesome, thanks everybody!
  • Sizeable donation from Handshake Foundation
    We’re glad to announce that we received donation of 100,000 USD, which is part of 300,000 USD offered to our KDE organization. Quite appropriate for a birthday present, as the KDE project just turned 22 this last weekend! It’s true recognition for KDE as one of the world’s largest open source project.

GNOME: Restyling, Geoclue and Outreachy

  • Restyling apps at scale
    Over the past few months we’ve had a lively debate about “theming” in GNOME, and how it affects our ecosystem. In this discussion I’ve found that there is a divide between people who design and/or develop apps, and people who don’t. I have yet to see an app developer who thinks the current approach to “theming” can work, while many people who aren’t app developers are arguing that it can. After a few long discussions I started to realize that part of the reason why there’s so little agreement and so much drama around this issue is that we don’t agree what the problem is. Those who don’t work on apps often can’t see the issues with theming and think we want to remove things for no reason, while those who do are very frustrated that the other side doesn’t want to acknowledge how broken everything is.
  • Geoclue 2.5 & repeating call for help
    Also, while I'm at it, I wanted to highlight the "call for help" at the end of that post by repeating it here again. I apologize of repeating to those who already read it but a friend pointed out that it's likely going to be missed by many folks: The future of Mozilla Location Service When Mozilla announced their location service in late 2013, Geoclue became one of its first users as it was our only hope for a reliable WiFi-geolocation source. We couldn't use Google's service as their ToC don't allow it to be used in an open source project (I recall some clause that it can only be used with Google Maps and not any other Map software). Mozilla Location Service (MLS) was a huge success in terms of people contributing WiFi data to it. I've been to quite a few places around Europe and North America in the last few years and I haven't been to any location, that is not already covered by MLS.
  • Making a first contribution in Outreachy usability testing
    If you want to join us in GNOME usability testing as part of the upcoming cycle in Outreachy, you'll need to make a first contribution as part of your application process. Every project in Outreachy asks for a first contribution; this is a requirement in Outreachy. Don't make too big of a deal about your first contribution in usability testing. We don't expect interns to know much about usability testing as they enter the internship. Throughout the internship, you'll learn about usability testing. So for this first contribution, we set a low bar.

Kali Linux: What You Must Know Before Using it

Kali Linux is the industry’s leading Linux distribution in penetration testing and ethical hacking. It is a distribution that comes shipped with tons and tons of hacking and penetration tools and software by default, and is widely recognized in all parts of the world, even among Windows users who may not even know what Linux is. Because of the latter, many people are trying to get alone with Kali Linux although they don’t even understand the basics of a Linux system. The reasons may vary from having fun, faking being a hacker to impress a girlfriend or simply trying to hack the neighbors’ WiFi network to get a free Internet, all of which is a bad thing to do if you are planning to use Kali Linux.
