  • Implementing Gtk based Container-Widget: Part — 2

    This write-up is in continuation of its previous part — setting up basic container functionality.

    In the past couple of weeks, we moved on from just adding children to actually repositioning them (child widgets of the container, NewWidget) when enough space is not available for all widget to fit in the given width. Though the grid structure is yet to put in place, the widget could be seen taking shape already (look at below gif).

  • This week in GNOME Builder #2

    This week we fixed some specific topics which were planned for the previous cycle. If anyone wants to contribute so see some of our “Builder wishlist” go there: Builder/ThreePointThirtyfive

    Last time i had forgotten to mention the great work of our translation team which contributed various translations to Builder. Thank you!

  • Synopsys DesignWare ARC HS CPUs Now Supported By GNU C Library

    The Synopsys DesignWare ARC HS is designed for high performance embedded environments with the 32-bit HS5x and 64-bit HS6x series. Synopsys has long offered their own GNU toolchain builds to support the DesignWare ARC hardware on Linux while now the mainline support is in good shape with glibc for the ARCv2 ISA having been mainlined. Though do note it's ARCv2 and not the latest ARCv3 ISA.

  • A FIXIT-dive into an old CPAN module

    Let’s have a thought experiment. Assume there is an Open Source-licensed Perl module published on CPAN that you care about, and that hasn’t had any updates in a very long time - what are your options?

    In this blog post, I’ll take a dive into this problem, and use the Geo::Postcodes::NO module as an example. As of this writing, the module version is 0.31, and it’s most recent release was in September 2006.

    [...]

    Contribution information for the module is missing (or at least, less than expected). The author ARNE has offered his email address, and after a quick search one can find his Github page. He hasn’t published this module there, though. If we are going to contribute with this, then just adding a CONTRIBUTING.md file is a probably a good place to start. If the module you are looking for has the same problem, then check out it’s “How to contribute” page on MetaCPAN (you can find a link to it in the menu there).

    There’s another issue though – we can’t offer a pull-request! At best we can send a patch(1) file attached to an email. While this is a bit old-school and should still work (assuming the author accepts those), there might be better options available.

  • Chapter 3 - Google Correlate example update

    In Chapter 3 on Page 87, the book refers to the Google Correlate service. However, as of December 2019, the service has been shutdown. Since the chapter requires you to download a CSV formatted data, it is no longer possible. However, you can instead download a version of the data that I had used 5 years back when writing the book from here.

Our favorite open source writing tools

Writing is one of the primary ways we communicate, and it's endlessly fascinating to see the different ways writers work. I can hardly imagine writing before computers and their ability to instantly edit and rearrange the words I've typed onto a screen. Likewise, I wonder whether people who started out writing on a typewriter process their thoughts differently, even on a modern word processor, or whether their workflow has changed and adapted because of these new tools. We asked some of our correspondents how they get their thoughts into comprehensible words and what open source tools they prefer while doing so. As you might expect, we got different answers from everyone who answered. Read more

  • FLOSS Weekly 591: PLATO & The Rise of Cyberculture - Programmed Logic for Automatic Teaching Operations

    P.L.A.T.O. is an acronym for Programmed Logic for Automatic Teaching Operations. Before the internet, there was the PLATO system which was not only computer-based education but, surprisingly, the first online community. Doc Searls talks with Shawn Powers and Brian Dear who was the author of Friendly Orange Glow which is the first book on PLATO. The book discusses the importance of PLATO. PLATO was the original incubator for social computing: instant messaging, chat rooms, message forums, the world's first online newspaper, and so much more. PLATO also created flat-panel gas plasma displays and was one of the first systems with touch panels built-in to the screen. They discuss how PLATO and the rise of the cyberculture and the internet were due to the "Hacker Method" an agreement among early developers to share and have open code.
