  • NVIDIA Extends PhysX for High Fidelity Simulations, Goes Open Source

    NVIDIA PhysX, the most popular physics simulation engine on the planet, is going open source.

    We’re doing this because physics simulation — long key to immersive games and entertainment — turns out to be more important than we ever thought.

    Physics simulation dovetails with AI, robotics and computer vision, self-driving vehicles, and high-performance computing.

  • NVIDIA have now made PhysX open source

    Popping up a little while ago on Twitter, NVIDIA has announced that they've now put PhysX under an open source license.

    Something I am sure many game developers and the open source community will approve of. Writing about it on their official blog, NVIDIA said "We’re doing this because physics simulation — long key to immersive games and entertainment — turns out to be more important than we ever thought.".

  • NVIDIA Makes PhysX Open-Source

    As a very big surprise bundled alongside the announcement today of the $2,499 USD TITAN RTX graphics card is word that NVIDIA's PhysX software is going open-source!

    It was a decade ago that NVIDIA acquired PhysX from their acquisition of AGEIA Technologies who at the time was working on Physics Processing Units. Since then, PhysX has become tightly coupled with NVIDIA GPUs and CUDA, but now the company is deciding to open-source it.

Open Science Means Open Source--Or, at Least, It Should

Why open source was actually invented in 1665.

When did open source begin? In February 1998, when the term was coined by Christine Peterson? Or in 1989, when Richard Stallman drew up the "subroutinized" GNU GPL? Or perhaps a little earlier, in 1985, when he created the GNU Emacs license? How about on March 6, 1665? On that day, the following paragraph appeared...

Those words are to be found in the very first issue of the Royal Society's Philosophical Transactions, the oldest scientific journal in continuous publication in the world, which published key results by Newton and others. Just as important is the fact that it established key principles of science that we take for granted today, including the routine public sharing of techniques and results so that others can build on them—open source, in other words.

  • Meet an opinionated quickstart for Sphinx docs authors

    Are you someone who writes documentation with the Sphinx tool chain? Do you want to encourage more people to write documentation in a distributed organization, but worry about maintaining compatible workflows? Introducing sphinx-docs-opinionated-quickstart, a template repository with an opinionated configuration of ReStructuredText documentation with Travis CI testing and readthedocs.org publishing.

    I created this for the RIT Linux User’s Group (a.k.a. RITlug). RITlug welcomes student-led projects for members to work on together. RITlug executive board members want to better encourage students to share and join projects for collaboration with the community (in the spirit of FOSS). To do this, the executive board members will create and offer both a template website and template documentation tools to introduce students to project development process. Then, students are better able to sustain a more diverse community around their projects.

  • The digital open-source future of scientific research in Europe

    According to Carlos Moedas, EU Commissioner for Research, Science, and Innovation “Science should have no borders.” This is the idea that prompted the setting up of Europe’s “digital coffeehouse” known as the European Open Science Cloud (EOSC), officially unveiled on 23 November at the University of Vienna, Austria.

    The first influx of funding for the EOSC will come from the European Commission, with a promise to invest €600 million to support the core functions of the EOSC up until 2020. Further financial support may come from a mix of funding sources, such as deposit fees from national funders, user-generated revenues.

    TheEuropean Commission also announced a team of eleven that will run the huge EOSC project, who were selected from the European research infrastructure and public research and funding organisations. Karel Luyben, vice president for research at CESAER ― a European association of 50 leading universities of science and technology in 25 countries ― was named as chair of the executive board, which will set the future directions of the cloud. Together with two additional management layers, a governance board and a stakeholder forum, the board will outline the annual work plans and rules of participation. The Commission will announce another team in January 2019 to run the stakeholder forum and deal with scientific outreach.

  • WebP image file sizes compared to equivalent Guetzli and Zopfli

    I decided to offer WebP images in addition to the traditional JPEG and PNG formats after Microsoft Edge and then shortly after Mozilla Firefox added support for the format. However, I did so blindly assuming that WebP would always produce smaller files without checking my that it actually did what I wanted. A reader called me out on my mistake and pointed out some WebP images were 15 % larger than the traditional file format.

    As discussed previously, I use libvips for image processing and preparing thumbnails from my source images. I’ve previously used libgd, but that created unwanted artifacts that hurt compression levels. However, I also use post-processing with the image optimization tool Guetzli for JPEG images and Zopfli for PNG images. These tools really help to slash image sizes without compromising on image quality but at the cost of significant memory and processor utilization (a one-time investment).

  • Cutting 3D Printing Costs with an Open Source Material Pelletizer

    Good filament can be pricey, although the polymers the filament is made from aren’t that expensive. That’s the opening observation of a paper entitled “3-D Printable Polymer Pelletizer Chopper for Fused Granular Fabrication-Based Additive Manufacturing.” The authors argue that the markup can be avoided by eliminating the process of creating filament and instead 3D printing directly from polymer granules. Fused granular fabrication (FGF), or fused particle fabrication (FPF), they point out, is held back by the lack of accessibility to low-cost pelletizers and choppers. So they developed their own open-source 3D printable pelletizer that can process both single thermopolymers as well as composites.

  • IBM's Big Bet On 'Hybrid' Cloud, Will It Work?
  • Open Source Hits The Big Time With Red Hat

    The proposed acquisition of Red Hat by IBM, the largest-ever software deal in history, is obviously important from the signalling: it means that the open-source movement has finally arrived. If a firm that offers paid services around freely available source code (much of it written by volunteers) is valued at the astronomical sum of $34 billion, it surely suggests open source is now viable. It is the ultimate triumph of the ‘bazaar’ over the ‘cathedral’ as suggested by Eric Raymond in his seminal, eponymous paper some time ago: barely-organised chaos has defeated the hierarchical, top-down organisation.

    It is surely ironic that IBM, the ultimate in buttoned-down, rule-bound, navy-blue-suited firms (although I hear the tie is now optional even if the white shirt remains de rigeur) should be the one buying the biggest player in the Linux-Apache-mySQL world of be-sandaled, bearded, shorts-wearing geeks infused with the libertarian cry that “software yearns to be free” or words to that effect from the arch-priest of that cult, Richard Stallman of the Free Software Foundation.

    For, IBM was for long the epitome of the closed, hierarchical ‘cathedral’ as opposed to the ‘bazaar’ (though Microsoft took on the cathedral mantle later). It was the object of hatred by legions of computer science students, who decried its monolithic, impenetrable operating systems such as for the System/370 mainframes, the corporate staples in the bad old days of the 1970s. (Operating systems are the most core software of computers, the innards of the system that give them their character, such as Windows, Apple iOS, or Android).

    In fact, it was as an act of rebellion against the work of thousands of programmers and their inscrutable code at IBM that the legendary Ken Thompson and Dennis Ritchie at AT&T’s Bell Labs wrote UNIX as a small, transparent operating system. It was a disruptive innovation, and it created a paradigm shift: here was the guts of the machine (reminiscent of Tracy Kidder’s The Soul of a New Machine) done by just two creative people, not an entire army of drone-like, faceless souls (as suggested in Apple’s famous ‘1984’ commercial where IBM is the Big Brother analog).

    In some circles, experts believe open source is on the wane. I strongly disagree. At its best, open source software explodes barriers to progress and accelerate innovation in ways licensed software with all its legislative impediments can only dream about. Furthermore, adopting open software as a strategy means users can add value and diversify with more speed and flexibility than ever before – all while raising overall operational standards.

  • Open Source powers innovation, transformation across government

    For government users, open source is no longer a bleeding-edge technology. Open source tools are powering innovation and transformation across government agencies because they offer affordable, secure, and innovative alternatives to traditional solutions.

    An open source approach allows developers to download code, start building prototypes and deploy solutions that meet their agency’s mission needs within days or weeks instead of months. It’s a far cry from the traditional government technology procurement cycle which often taking years from procurement to installation. Moreover, that solution still may not fully deliver on what was promised after being in development for years. Open source solutions don’t just shorten the procurement and development cycle, they also give developers and system users more confidence that the solutions will actually work because it’s faster and less expensive to build working proof of concepts (POCs).

  • 20 Years of Open Source: Why the Best Payment APIs Use Shared Code

    Although the idea of open source has been around since the pre-internet days of the early 20th century, its modern meaning dates back to early 1998. In these days, free software was a much more prevalent term that promoted the idea of “users have the freedom to run, copy, distribute, study, change and improve the software.” This concept is still around today, with many of its devotees, including Richard Stallman, the creator of the Free Software Movement (FSM), claiming it to be more accurate than what we now call open source software.

    Disagreements over the interpretation, actual and perceived, are what pushed the creators of the Open Source Initiative (OSI) to challenge the status quo. Since the idea of free software is more figurative than literal (think of “free speech,” not “free beer,” as Stallman puts it), open source software was meant to clarify the meaning behind the term and encourage companies to get on board with it.

Applications that used Android's SlidingDrawer library enabled users to hide content offscreen, then drag it onscreen using a "handle" when they wanted to use it. Unfortunately, the library was deprecated in Android 4.2, JellyBean (API 17), but independent developers have stepped in to create alternative versions for those who miss the cool animation and better UI experience it offered.

In this tutorial, we'll create a Sliding Drawer interface with SlidingRootNav, an open source alternative that is very easy to implement.

Foreword ======== I'd like to start by thanking Christian Perrier, who spent many years working on Debian Installer, especially on internationalization (i18n) and localization (l10n) topics. One might remember graphs and blog posts on Planet Debian with statistics; keeping track of those numbers could look like a pure mathematical topic, but having uptodate translations is a key part of having a Debian Installer that is accessible for most users. Thank you so much, Christian! Read more Also: Debian Installer Buster Alpha 4 Released
