  • Here’s Why Running Linux Distros In VirtualBox Is About To Get Much Better

    With the help of hypervisors like Oracle VirtualBox, one can run operating systems within another pre-installed host operating system and try out the features. When it comes to Linux, the beginners are often advised to try out user-friendly Linux distros in a virtual machine before making the brave jump.

  • Dillinger – A Cloud-Enabled HTML5 Markdown Editor

    Our post today is about another Markdown editor – one that has been termed “the last Markdown editor you will ever use“, presumably because of its full-featured Markdown support and free accessibility.

    We told you about StackEdit the last time so today, we introduce to you, Dillinger.

    Dillinger is an AngularJS powered online HTML5 Markdown editor that is mobile ready, cloud-enabled, supports live preview and offline document storage.

    GNU developers are preparing to quickly ship GCC 7.3 now in order to get out the Spectre patches, a.k.a. the compiler side bits for Retpoline with -mindirect-branch=thunk and friends.

    It was just this past weekend that the back-ported patches landed in GCC 7 while now GCC 7.3 is being prepared as the branch's next bug-fix point release.

  • Announcing LibrePlanet 2018 keynote speakers

    The keynote speakers for the tenth annual LibrePlanet conference will be anthropologist and author Gabriella Coleman, free software policy expert and community advocate Deb Nicholson, Electronic Frontier Foundation (EFF) senior staff technologist Seth Schoen, and FSF founder and president Richard Stallman.

    LibrePlanet is an annual conference for people who care about their digital freedoms, bringing together software developers, policy experts, activists, and computer users to learn skills, share accomplishments, and tackle challenges facing the free software movement. The theme of this year's conference is Freedom. Embedded. In a society reliant on embedded systems -- in cars, digital watches, traffic lights, and even within our bodies -- how do we defend computer user freedom, protect ourselves against corporate and government surveillance, and move toward a freer world? LibrePlanet 2018 will explore these topics in sessions for all ages and experience levels.

Open Source in 3-D Printing

  • 17,000% Cost Reduction with Open Source 3D Printing: Michigan Tech Study Showcases Parametric 3D Printed Slot Die System

    We often cover the work of prolific Dr. Joshua Pearce, an Associate Professor of Materials Science & Engineering and Electrical & Computer Engineering at Michigan Technological University (Michigan Tech); he also runs the university’s Open Sustainability Technology (MOST) Research Group.

    Dr. Pearce, a major proponent for sustainability and open source technology, has previously taught an undergraduate engineering course on how to build open source 3D printers, and four of his former students, in an effort to promote environmental sustainability in 3D printing, launched a business to manufacture and sell recycled and biodegradable filaments.

  • Open Source 3D printing cuts cost from $4,000 to only $0.25 says new study

    Slot die coating is a means of adding a thin, uniform film of material to a substrate. It is a widely used method for the manufacturing of electronic devices – including flat screen televisions, printed electronics, lithium-ion batteries and sensors.

    Up until recently, slot die components were only machined from stainless steel, restricting development and making the process expensive. Now slot dies for in-lab experimental use can be made on a 3D printer at a fraction of the cost.

  • Dutch firm unveils world's first 3-D-printed propeller

    Three-dimensional (3-D) printing technology has caught the logistics world's attention for its potential to save on warehouse and shipping costs by producing items on demand at any location. In the past two years, for example, UPS Inc. announced plans to partner with software developer SAP SE to build a nationwide network of 3-D printers for use by its customers, and General Electric Co. spent nearly $600 million to buy a three-quarters stake in the German 3-D printing firm Concept Laser GmbH.

    Recently, transportation companies have begun turning to the same technology for another application, creating the actual hardware used in vehicles that move the freight. For instance, in late 2016, global aircraft maker Airbus S.A.S. contracted with manufacturing firm Arconic Inc. to supply 3-D printed metal parts for its commercial aircraft.

  • RadeonSI NIR Backend Now Supports GLSL 4.50

    The experimental RadeonSI NIR back-end is taking a final step forward for Mesa 18.0.

    Up until today when using the RadeonSI NIR code-path the GLSL (OpenGL Shading Language) version was limited to 1.50 due to not having any tessellation shader support, but now it's supported up through 4.50 -- the GLSL version matching OpenGL 4.5.

  • RADV Vulkan Driver Now Supports VK_EXT_debug_report

    With the flurry of Mesa development activity with Mesa 18.0 being branched in a few days, the RADV Radeon Vulkan driver picked up support for another extension.

    Building off groundwork laid by Intel ANV, the RADV driver now implements VK_EXT_debug_report. At the moment it doesn't output any messages but can be easily added during development for usage with RenderDoc and other Vulkan debuggers.

  • The DRM Graphics Driver Changes Coming For Linux 4.16

Will 2018 Be the Year of the Linux Desktop

Filed under
GNU
Linux

The “Year of the Linux Desktop” is a fabled time when Linux finally rises up and becomes the dominant desktop operating system, supplanting Windows.

Now, that might sound ridiculous, but the notion has been fueled over the years by Linux’s rise to dominance in every other market. The vast majority of servers run Linux. Just about every supercomputer runs on Linux. If you have an Android phone, it’s running the Linux kernel. Even the Internet of Things and automotive computers are primarily running some variation of Linux.

    The plan goes beyond just picking and choosing the best open-source alternatives to Microsoft products out there, as Barcelona will apparently be hiring developers to create bespoke software. The idea is that these projects could potentially be rolled out across other Spanish cities if they’re up to the task.

It’s not a hidden fact that Google has been using Ubuntu-based Linux distribution called Goobunu for years.

The home-baked distribution used by Google engineers is like a light skin on top of Ubuntu Linux LTS releases. The company has been a customer of Canonical as part of the Ubuntu Advantage Program, so it shouldn’t come as a surprise.

  • Benchmarking Retpoline Underflow Protection With Intel Skylake/Kabylake

    Beyond the Retpoline support already found in the mainline Linux kernel, developers are working on Retpoline Underflow support that would be used for Intel Skylake and Kabylake CPUs. RETPOLINE_UNDERFLOW protects against falling back to a potentially poisoned indirect branch predictor when a return buffer underflows and this additional protection is needed for Intel Skylake/Kabylake processors. I ran a couple benchmarks.

  • This week in Discover

    I guess I’m becoming a Discover developer, since it’s where I seem to spend most of my time these days. It’s just so darn fun since the lead Developer Aleix Pol is super easy to work with, there’s a lot of low-hanging fruit, and with Kirigami, it’s very simple to make consequential changes even when you’re a novice programmer and not very familiar with the codebase. That said, Aleix is still making about 99% of the code changes, and I’m mostly doing UI tweaks, bug screening, promotion, strategy, and work with apps to get their houses in order.

  • Librem 5 Phone Progress Report – The First of Many More to Come!

    First, let me apologize for the silence. It was not because we went into hibernation for the winter, but because we were so busy in the initial preparation and planning of a totally new product while orienting an entirely new development team. Since we are more settled into place now, we want to change this pattern of silence and provide regular updates. Purism will be giving weekly news update posts every Tuesday, rotating between progress on phone development from a technology viewpoint (the hardware, kernel, OS, etc.) and an art of design viewpoint (UI/UX from GNOME/GTK to KDE/Plasma). To kickoff this new update process, this post will discus the technological progress of the Librem 5 since November of 2017.

An introduction to Inkscape for absolute beginners

Filed under
OSS

Inkscape is a powerful, open source desktop application for creating two-dimensional scalable vector graphics. Although it's primarily an illustration tool, Inkscape is used for a wide range of computer graphic tasks.

The variety of what can be done with Inkscape is vast and sometimes surprising. It is used to make diagrams, logos, programmatic marketing materials, web graphics, and even for paper scrapbooking. People also draw game sprites, produce banners, posters, and brochures. Others use Inkscape to draft web design mockups, detail layouts for printed circuit boards, or produce outline files to send to laser cutting equipment.

Interviews
Ubuntu

In October, Linux PC maker System76 released its homegrown version of Linux, Pop!_OS, giving users the choice between its legacy Ubuntu operating system or the new Pop!_OS flavor of Linux. Recently Opensource.com gave away a System76 laptop with Pop!_OS installed, which made me curious about the company and this new version of Linux, so I spoke with Cassidy James Blaede, Pop!_OS's user experience (UX) designer.

Blaede joined System76 in 2014, fresh out of college at the University of Northern Iowa and marriage to his wife, Katie. While in college, he co-founded the elementary OS project and interned at UX consultancy Visual Logic, both of which influenced his work for System76. He started at System76 as a front-end developer and was later promoted to UX architect.

  • HHVM 3.24 Released, The Final Supporting PHP5

    The Facebook crew responsible for the HHVM project as a speedy Hack/PHP language implementation is out with its 3.24 release.

    HHVM 3.24 is important as it's the project's last release focusing on PHP5 compatibility. Moving forward, PHP5 compatibility will no longer be a focus and components of it will likely be dropped. As well, Facebook will be focusing on their Hack language rather than PHP7. Now that PHP7 is much faster than PHP5 and all around in a much better state, Facebook developers are focusing on their Hack language rather than just being an alternative PHP implementation.

  • How to get into DevOps

    I've observed a sharp uptick of developers and systems administrators interested in "getting into DevOps" within the past year or so. This pattern makes sense: In an age in which a single developer can spin up a globally distributed infrastructure for an application with a few dollars and a few API calls, the gap between development and systems administration is closer than ever. Although I've seen plenty of blog posts and articles about cool DevOps tools and thoughts to think about, I've seen fewer content on pointers and suggestions for people looking to get into this work.

  • RcppMsgPack 0.2.1

    Am update of RcppMsgPack got onto CRAN today. It contains a number of enhancements Travers had been working on, as well as one thing CRAN asked us to do in making a suggested package optional.

    MessagePack itself is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it is faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves. RcppMsgPack brings both the C++ headers of MessagePack as well as clever code (in both R and C++) Travers wrote to access MsgPack-encoded objects directly from R.

  • A Modularity rethink for Fedora
    We have covered the Fedora Modularity initiative a time or two over the years but, just as the modular "product" started rolling out, Fedora went back to the drawing board. There were a number of fundamental problems with Modularity as it was to be delivered in the Fedora 27 server edition, so a classic version of the distribution was released instead. But Modularity is far from dead; there is a new plan afoot to deliver it for Fedora 28, which is due in May. The problem that Modularity seeks to solve is that different users of the distribution have differing needs for stability versus tracking the bleeding edge. The pain is most often felt in the fast-moving web development world, where frameworks and applications move far more quickly than Fedora as a whole can—even if it could, moving that quickly would be problematic for other types of users. So Modularity was meant to be a way for Fedora users to pick and choose which "modules" (a cohesive set of packages supporting a particular version of, say, Node.js, Django, a web server, or a database management system) are included in their tailored instance of Fedora. The Tumbleweed snapshots feature of the openSUSE rolling distribution is targeted at solving much the same problem. Modularity would also facilitate installing multiple different versions of modules so that different applications could each use the versions of the web framework, database, and web server that the application supports. It is, in some ways, an attempt to give users the best of both worlds: the stability of a Fedora release with the availability of modules of older and newer packages, some of which would be supported beyond the typical 13-month lifecycle of a Fedora release. The trick is in how to get there.
