  • Quarking Drools: How we turned a 13-year-old Java project into a first-class serverless component

    Rule-based artificial intelligence (AI) is often overlooked, possibly because people think it’s only useful in heavyweight enterprise software products. However, that’s not necessarily true. Simply put, a rule engine is just a piece of software that allows you to separate domain and business-specific constraint from the main application flow. We are part of the team developing and maintaining Drools—the world’s most popular open source rule engine and part of Red Hat—and, in this article, we will describe how we are changing Drools to make it part of the cloud and serverless revolution.

  • Why feedback, not metrics, is critical to DevOps

    Most managers and agile coaches depend on metrics over feedback from their teams, users, and even customers. In fact, quite a few use feedback and metrics synonymously, where they present feedback from teams or customers as a bunch of numbers or a graphical representation of those numbers. This is not only unfortunate, but it can be misleading as it presents only part of the story and not the entire truth.

  • L2TP Tunnel Support Added To Systemd

    The newest feature addition for systemd is supporting L2TP, the Layer 2 Tunneling Protocol, as part of its networking code. 

    Systemd's networkd now has support merged for LT2TP tunnel support. L2TP can be used for extending a local area network (LAN) or also for VPN purposes when paired with the likes of IPsec for providing encryption. L2TP also has a variety of other use-cases with this bare protocol able to offer a layer two link over an L3 network.

  • libinput 1.12.901
    The first RC for libinput 1.13 is now available.
    
    
    
    
    Only two notable features in this release but patches are accumulating on
    master, it's been 6 months since 1.12 and I've decided to postpone the two
    major features (hi-res scrolling and totem support) to 1.14.
    
    
    
    
    Touch arbitration has improved for tablets, especially on touch screens.
    A timer set on pen proximity out means we don't get ghost touches anymore
    when the hand lifts off slower than the pen itself. And location-based touch
    arbitration means that parts of the screen can be interacted with even while
    the pen is in proximity. libinput uses the tilt information where
    available to disable touches in a rectangle around the pen where the hand is
    likely to be but leaves the rest of the touchscreen available otherwise.
    Where the UI supports it, this allows for bimanual interaction.
    
    
    
    
    The test suite is installed on demand (meson -Dinstall-tests=true). Where
    run from the installed location it will use the normal library lookups and
    the quirks directory as defined by the prefix. This makes it useful for
    distribution-level testing, i.e. run this on a test machine after updating
    the package to make sure everything is as expected. Where available, you can
    invoke it with the "libinput test-suite" command.
    
    
    
    
    Other than that, a load of fixes, quirks added, cleanups, tidy-ups and so on
    an so forth.
    
    
    
    
    As usual, the git shortlog is below. Many thanks to all the contributors.
  • Libinput 1.13 Is Coming But High-Resolution Scrolling & Dell Totem Support Delayed

    Libinput is fairly mature at this stage for offering a unified input handling library for use on both X.Org and Wayland Linux desktops. Libinput has largely reached a feature plateau with new releases no longer coming out so often and no glaring gaps in support. With it already being a half-year since the last major release, libinput 1.13 is now being buttoned up for release and available today is the first release candidate. 

    Libinput 1.13 isn't that exciting of a release particularly since maintainer Peter Hutterer of Red Hat decided to delay the high resolution scrolling support. The Linux 5.0 kernel brought the much anticipated high resolution scrolling support for various Logitech/Microsoft mice to improve the scroll-wheel experience. Besides the kernel support, there is also the user-space support that needs updating. Peter decided to delay this functionality now until Libinput 1.14 to give it more time to bake.

Programming/Development: Python Natural Language Processing, DevNation Federal, KTextEditor/Kate, Blender3D

  • Top 10 Python NLP Libraries For 2019
    With the help of Natural Language Processing, an organisation can gain valuable insights, patterns, and solutions. Python is one of the widely used languages and it is implemented in almost all fields and domains. In this article, we list down 10 important Python Natural Language Processing Language libraries.
  • DevNation Federal brings open source to the Beltway
    On June 27th, Red Hat will not only be hosting one of the best technical gatherings of 2019, but it will be doing so in Washington D.C. — not San Francisco, Seattle, or ... DevNation Federal conference will bring together industry experts and key maintainers of popular open source projects in a one-day immersive conference for federal developers.
  • KTextEditor/Kate Bugs – Help Appreciated
    The bug report count of KTextEditor (implementing the editing part used in Kate/KWrite/KDevelop/Kile/…) and Kate itself reached again some value over 200. If you have time and need an itch to scratch, any help to tackle the currently open bugs would be highly appreciated. The full list can be found with this bugs.kde.org query. [...] The team working on the code is small, therefore please be a bit patient if you wait for reactions. I hope we have improved our reaction time in the last months but we still are lacking in that respect.
  • Blender3D User interface and API Freeze
    In the last month, we’ve polished the user interface and added the last planned features to Blender 2.80. The details can be found in the weekly development notes. Now we are freezing the user interface, so that there is a stable base for creating documentation and tutorials. Settings will stay in the same place and screenshots should remain valid for the final 2.80 release. A handful of menu entries may be added, or a tooltip might be improved, but nothing major that would break documentation.
  • Blender 2.80 Reaches Its API & UI Freeze
    In order to meet the July release target for Blender 2.80, there is now an API and user-interface freeze on this next feature update for this leading open-source, cross-platform 3D modeling software. Blender 2.80 has now entered its UI and API freeze milestone for the 2.80 release. The Blender settings should also be maintained now moving forward for the Blender 2.80 release and its Python API compatibility, including for add-ons.

Additionally, the root user password is set to root. It is strongly recommended to change the password for both users after gaining access to the system.
  • FreeBSD 11.3 Enters Beta Ahead Of July Release
    While FreeBSD 12 is the latest and greatest stable series since the end of last year, for those still on FreeBSD 11 there is the 11.3 update due out for release in July while this weekend the first beta was issued. FreeBSD 11.3 offers up the latest security updates and other stable bug fixes over FreeBSD 11.2 that was released nearly one year ago. But for those craving all the latest features and functionality, FreeBSD 12 is in release form or there is also FreeBSD 13-CURRENT.

Best Command-Line FTP Clients for Linux

File Transfer Protocol (FTP) is a network protocol used for transferring files between a client and a server on a computer network. The very first FTP applications were made for the command line before GUI Operating Systems even became a thing and while there are several GUI FTP clients, developers still make CLI-based FTP clients for users who prefer using the old method. Here’s a list of the best command-line based FTP clients for Linux. Read more
