Parrot is prepping two Linux-based mini-drones: a $160 “Jumping Sumo” wheeled robot and a $100 “Rolling Spider” quadrocopter that can fly, roll, or climb.

Parrot, which last month announced a Bebop successor to its popular AR.Drone 2.0 quadrocopter, has released new information on two smaller, cheaper mini-drones that were originally unveiled back at CES in January. The Jumping Sumo and Rolling Spider will launch in August for $160 and $100, respectively.

The Next Open Source Battle Is Being Waged In The 3D Printing Industry

Sci/Tech

More than twenty years ago, Linux began wending its way out of the primordial soup that was the early Internet and ensconcing itself in servers and workstations around the world.

After its creation in 1991 it took another eight years or so to be widely recognized, but during that period, arguments arose as to what Linux really was. Could Red Hat, a company founded in 1993, sell services around it? Who made money when you sold a CD containing the latest version of Mandrake Linux? Who owned code written on top of Linux for specific purposes? To the open source community, the answers to all those questions was “No one. The community owned Linux.”

3D Printing's Next Revolution: Linux

Hardware
Sci/Tech

3D printers may be trendy, but they are hardly new. One of the earliest of all is the RepRap project, which began back in 2005. As its name implies - it's short for "replicating rapid" prototyper - RepRap is designed to be able to produce copies of itself, or at least most of its parts. Not only that, it is completely open source, both in terms of its hardware (which uses Arduino kit) and software.

Because of its open nature it has gone on to form the basis of many other 3D-printing systems, including those from MakerBot.

Licensing: Facebook Responds to Licence Complaints, Cloud Native Open Source License Choices Analysed

  • Facebook relicenses several projects
    Facebook has announced that the React, Jest, Flow, and Immutable.js projects will be moving to the MIT license. This is, of course, a somewhat delayed reaction to the controversy over the "BSD+patent" license previously applied to those projects.
  • Relicensing React, Jest, Flow, and Immutable.js
    Next week, we are going to relicense our open source projects React, Jest, Flow, and Immutable.js under the MIT license. We're relicensing these projects because React is the foundation of a broad ecosystem of open source software for the web, and we don't want to hold back forward progress for nontechnical reasons. This decision comes after several weeks of disappointment and uncertainty for our community. Although we still believe our BSD + Patents license provides some benefits to users of our projects, we acknowledge that we failed to decisively convince this community.
  • Cloud Native Open Source License Choices
    One of the most common questions regarding open source licensing today concerns trajectories. Specifically, what are the current directions of travel both for specific licenses as well as license types more broadly. Or put more simply, what licenses are projects using today, and how is that changing? We’ve examined this data several times, most recently in this January look at the state of licensing based on Black Duck’s dataset. That data suggested major growth for permissive licenses, primarily at the expense of reciprocal alternatives. The Apache and MIT licenses, for example, were up 10% and 21% respectively, while the GPL was down 27%. All of this is on a relative share basis, of course: the “drop” doesn’t reflect relicensing of existing projects, but less usage relative to its peers. [...] One such community with enough of a sample size to be relevant is the one currently forming around the Cloud Native Computing Foundation. Founded in 2015 with the Kubernetes project as its first asset, the Foundation has added eleven more open source projects, all of which are licensed under the same Apache 2 license. But as a successful Foundation is only a part of the broader ecosystem, the real question is what are the licensing preferences of the Cloud Native projects and products outside of the CNCF itself. [...] Unsurprisingly, perhaps, given the influence of the CNCF itself, Apache strongly outperforms all other licenses, showing far greater relative adoption than it has in more generalized datasets such as the Black Duck survey. Overall in this dataset, approximately 64% of projects are covered by the Apache license. No other project has greater than a 12% share. The only other licenses above 10%, in fact, are the GPL at 12% and MIT at 11%. After that, the other projects are all 5% or less.

    Half-Life: C.A.G.E.D. [Steam] is a mod from former Valve worker Cayle George, it's a short prison escape and it should be coming to Linux. Mr George actually worked on Team Fortress 2 and Portal 2 during his time at Valve, but he's also worked for other notable developers on titles like Horizon Zero Dawn.
  • Game Engine Powered Arcan Display Server With Durden Desktop Updated
    Arcan, the open-source display server powered by a game engine, is out with a new release. Its Durden desktop environment has also been updated. Arcan is a display server built off "the corpse of a game engine" and also integrates a multimedia framework and offers behavior controls via Lua. Arcan has been in development for a half-decade while its original code traces back more than a decade, as explained previously and has continued advancing since.
  • Arcan 0.5.3, Durden 0.3
    It’s just about time for a new release of Arcan, and way past due for a new release of the reference desktop environment, Durden. Going through some of the visible changes on a ‘one-clip or screenshot per feature’ basis:

KDE: Plasma 5.11 in Kubuntu 17.10, Krita 3.3, Randa and Evolution of Plasma Mobile

  • KDE Plasma 5.11 Desktop Will Be Coming to Kubuntu 17.10 Soon After Its Release
    KDE kicked off the development of the KDE Plasma 5.11 desktop environment a few months ago, and they've already published the Beta release, allowing users to get a first glimpse of what's coming in the final release next month. Canonical's Ubuntu Desktop team did a great job bringing the latest GNOME 3.26 desktop environment to the upcoming Ubuntu 17.10 (Artful Aardvark) operating system, and it looks like the Kubuntu team also want to rebase the official flavor on the forthcoming KDE Plasma 5.11 desktop environment.
  • Krita 3.3 Digital Painting App Promises Better HiDPI Support on Linux & Windows
    Work on the next Krita 3.x point release has started, and a first Release Candidate (RC) milestone of the upcoming Krita 3.3 version is now ready for public testing, giving us a glimpse of what's coming in the new release. In the release announcement, Krita devs reveal the fact that they were forced to bump the version number from 3.2.x to 3.3.x because the upcoming Krita 3.3 release will be introducing some important changes for Windows platforms, such as support for the Windows 8 event API, thus supporting the n-trig pen in Surface laptops.
  • Randa-progress post-hoc
    So, back in Randa I was splitting my energies and attentions in many pieces. Some attention went to making pancakes and running the kitchen in the morning — which is stuff I take credit for, but it is really Grace, and Scarlett, and Thomas who did the heavy lifting, and Christian and Mario who make sure the whole thing can happen. And the attendees of the Randa meeting who pitch in for the dishes after lunch and dinner. The Randa meetings are more like a campground than a 5-star hotel, and we work together to make the experience enjoyable. So thanks to everyone who pitched in. Part of a good sprint is keeping the attendees healthy and attentive — otherwise those 16-hour hacking days really get to you, in spite of the fresh Swiss air. [...] You can read more of what the attendees in Randa achieved on planet KDE (e.g. kdenlive, snappy, kmymoney, marble, kube, Plasma mobile, kdepim, and kwin). I’d like to give a special shout out to Manuel, who taught me one gesture in Italian Sign Langauage — which is different from American or Dutch Sign Language, reminding me that there’s localization everywhere.
  • The Evolution of Plasma Mobile
    Back around 2006, when the Plasma project was started by Aaron Seigo and a group of brave hackers (among which, yours truly) we wanted to create a user interface that is future-proof. We didn’t want to create something that would only run on desktop devices (or laptops), but a code-base that grows with us into whatever the future would bring. Mobile devices were already getting more powerful, but would usually run entirely different software than desktop devices. We wondered why. The Linux kernel served as a wonderful example. Linux runs on a wide range of devices, from super computers to embedded systems, you would set it up for the target system and it would run largely without code changes. Linux architecture is in fact convergent. Could we do something similar at the user interface level?
