  • Service composition in GuixSD

    GuixSD is not like your parents’ distro. Instead of fiddling with configuration files all around, or running commands that do so as a side effect, the system administrator declares what the system will be like. This takes the form of an operating-system declaration, which specifies all the details: file systems, user accounts, locale, timezone, system services, etc.

  • Meet HU-GO, the Open Source DIY Low-Cost Wheelchair with 3D Printed Parts

    Most able-bodied people don’t really understand exactly how expensive it is to be disabled in a world built for people who are not. I have heard several people, after reading an article about e-NABLE, comment about how shocked that they are at the cost of traditional prostheses. I would imagine that the same sticker shock would apply to those who have never had to purchase a wheelchair. On the low end, wheelchairs still cost several hundred dollars, but they can reach costs up into the thousands. And electric powered chairs are even more expensive, with prices often doubling the cost of their manual counterparts. That is hard for most people to afford in a developed country like the United States, but would be nearly impossible for a poor person in developing countries.

Changing Tack: Evolving Attitudes to Open Source

Filed under

What does it mean when an organization that saw software as an asset worth protecting commits to open source? Or one that viewed software as the ends rather than the means and had tens of billions of dollars worth of evidence supporting this conclusion? The short answer is that it means that open source is being viewed more rationally and dispassionately than we’ve seen since the first days of the SHARE user group.

Work Set on Open Source Compiler

Filed under

The U.S. Department of Energy’s National Nuclear Security Administration (NNSA) and its three national labs have reached an agreement with NVIDIA’s PGI® software to create an open source Fortran compiler designed for integration with the widely used LLVM compiler infrastructure.

LLVM (formerly Low Level Virtual Machine), a collection of reusable compiler and tool chain technologies with a modular design, facilitates support for a wide variety of programming languages and processor architectures. The Fortran front-end module created through this project will be derived from NVIDIA’s PGI Fortran compiler.

Parrot’s Bebop 2: smaller, faster, longer-lasting, Linux-fortified

Filed under

In San Francisco, Parrot unveiled a smaller, faster, longer lasting version of its Linux-based Bebop drone, helping to solidify its dominance in the mid-range consumer market. One of the key new features is an emergency cutoff that instantly kills the quadrotor motors when a blade hits an obstacle. The increasing focus on safety was also demonstrated this week when 3DR (Solo) and DJI (Phantom) announced similar new technology to make it easier for their customers to avoid restricted airspace (see farther below).

Why I chose Wordpress for my college football blog

Filed under

At this point, I started making WordPress websites—taking a theme and customizing it to create a branded site for companies. I definitely felt empowered. WordPress is open source, and I am grateful for this, as it has become the very core of many successful businesses across the globe. It is the core of what I do every day, whether writing, consulting, or developing a website.

  • Open source projects rely on donated time—what motivates participants?

    The study’s authors collected data from approximately a thousand R contributors who responded to a questionnaire distributed via e-mail. The respondents were asked about what drove them to participate in the project, with possible answers including taking pleasure in applying their skills and feeling a sense of responsibility toward the scientific community. They were also asked about extrinsic motivators, such as the potential that their work could help with academic advancement. Additionally, the surveys included questions about the characteristics of the software development work (e.g. repetitive, technical, social) and the demographics of participants.

  • Implementing open source requires tough staffing, IT calls
  • Import old email archives into Gmail using these open source tools from Google

    If you want to try these open source tools yourself, you can download them at Github (mail-importer and import-mailbox-to-gmail). Unfortunately, mail-importer appears to only support Thunderbird at this time. If you used a different client, you will need to wait for a future update. If you are savvy enough, maybe you can tweak the source to make it work. I have a large Lotus Notes archive saved -- I won't hold my breath on that one being anyone's priority.

    CMU today informed us that a team of its researchers is taking aim at the $10 million grand prize of the $15 million Global Learning XPRIZE competition, the goal of which is to empower children to take control of their own learning via tablet computers, software and the like. The competition was announced about a year ago.

  • LLVM's Clang Lands More CUDA Improvements

    Just days after writing about GPUCC as Google's open-source CUDA compiler built atop LLVM and how to compile CUDA code with LLVM, more improvements have landed.

    There's now support for CUDA compilation by default as one of the most prominent changes today. "Currently clang requires several additional command line options in order to enable new features needed during CUDA compilation. This patch makes these options default." That change was done by Artem Belevich at Google.

  • These Biohackers Are Creating Open-Source Insulin

    The 370 million people worldwide with diabetes rely on injections of insulin to regulate the amount of sugar in their blood, since their bodies can’t make the hormone themselves. Since there are no generic versions available in the United States, insulin is very expensive—that cost was likely a large proportion of the $176 billion in medical expenditures incurred by diabetes patients in 2012 alone. Now a team of biohackers with Counter Culture Labs, a community lab in Oakland, California, wants to pave the way towards generic insulin, and they’ve started a crowdfunding page for their project.

  • OpenCar wants to open source in-vehicle infotainment

    The OpenCar suite of offerings come together to work in a way similar to the software developer kits (SDK) offered for various tech and platforms. Everything from Web-based applications like WordPress to gadgets like the Apple Watch have developer kits associated with them so that third-party programmers can build software to work with them. In many ways, what OpenCar is offering is the platform for an SDK for in-car infotainment. Automakers still have to sign on and make their software compatible, but in return they can open their vehicle infotainment to outside developers without compromising its integrity or their control of the experience, branding, and legalities.

  • How will the children of the future learn about science?

    As our understanding of the world expands, it is important to ensure that that knowledge is equally accessible by all members of our society. This is vital to the progress of humanity. This philosophy, which is shared by the open source software movement, is not new; it has been around since the 1600s when the first academic journals were published for public reading. The Jupyter Notebook hints at what the academic journals of tomorrow will look like and paints a promising picture. They will be interactive, visualization-focused, user-friendly, and include code and data as first-class citizens. I believe that these unique characteristics will go a long way toward bridging the gap of understanding between the scientific community and the general public through both narrative and code—a gap that, when bridged, will have a significant impact on our society.

  • You might want to hug this book: a review of 'Git for Teams'

    Git has a bit of a reputation as being difficult to learn and even more difficult to master. Because it's such a powerful and flexible tool, it is easy for users to make hard-to-correct mistakes. When working with others, it becomes even easier to get out of sorts. Git for Teams aims to solve that problem by not only teaching the reader how to use Git, but how to use teams.
