  • Why Sustainable Software Needs a Change in the Culture of Science

    Open Source and good practice

    The challenge to the scientific community is how to do the work needed to make software sustainable. Either reducing the amount of work, or bringing together new resources, can make this more successful. The first is often thought of as using good software engineering practices (which has the additional benefit of making the software more likely to be correct), and the second can potentially be satisfied through Open Source communities.

    In some sense, these are both social issues, rather than technical ones. The goal is to encourage software developers, whatever the type of software they are developing, to do the extra work needed to make their own software sustainable and to build or join communities whose members work together on shared code. The task is how to achieve this.

  • NGINX Plus R8 Fully Supports HTTP/2, Field Tests OAuth2

    Fracturing a site’s contents into a plurality of arbitrary domains to improve performance is still being taught as a legitimate practice for Web servers. It remains the best way to get around HTTP 1.1’s maximum limitation of six connections per host, and the, even more, draconian limit of two connections for older browsers such as Internet Explorer 7.

  • In Memoriam of John McCreesh & FOSDEM 2016

    I was about to write about the main topic of this post, namely FOSDEM 2016 when we learned of the death of someone who was a really nice and gentle human being, John McCreesh. For those who may not know John, it’s important to say that while he was not as famous as Ian Murdock, he was definitely one of the pillars of the OpenOffice.org community for long years. He served as a volunteer there in various capacities, but mostly as one of the marketing project lead. During his tenure, he had to deal with complicated situations and several challenges. John was, I already wrote it, a gentle human being. He managed to help build and strengthen the OpenOffice.org community and make it bloom even when times were dire. He was nice, always listening to others, soothing and comforting people around him. John knew the value of peace and moving forward. His origins (he was born in Northern Ireland if I’m not mistaken and his family origins are quite interesting in that regard) and upbringing made him respect anyone who was coming towards him and his welcoming stance gained him many friends and many open source volunteers. In some cases, his generous and kind attitude helped him make people stay in the project even as they had every obvious reasons to leave.

  • VIDEO: Driverless tractors and open-source software

    The Inventors’ Showcase winner, and president of Reimer Robotics, has built a system to move tractors – driverless no less, with grain cart in tow – across a field to a harvesting combine on the go. Reimer’s invention can help producers save time during harvest – and since the software and hardware are open-source – other producers can build on his work and adapt it to their needs.

  • Open-source GPU from Binghamton University could shake up the industry

    GPU's are fantastic tools for completing scientific computational work. They're effective at calculating math that's highly parallel, doing it far faster than any CPU could do alone. And now the GPU is going open-source with Binghamton University's new Nyami architecture that researchers have developed.

  • What's New in 3D Printing, Part II: the Hardware

    This is the second article in what will be a four-part series on the current state of 3D printing compared to how things were three years ago when I wrote my first series on 3D printing. Of course, this is Linux Journal, so the focus will be on Linux and open-source-specific aspects in 3D printing. I won't dwell much on proprietary products. In my last article, I gave a general overview on the state of 3D printing; in this one, I focus on the hardware side.

    If you were to compare 3D printers three years ago to today, probably the first thing you would notice is just how polished and consumer-focused the overall look of the machines are now. Three years ago, most printers were based off the RepRap line of 3D printers. They had a hobbyist look, with 3D-printed gears and other parts combined with nuts and bolts you could get from the hardware store. Those printers that didn't consist of a series of threaded and smooth rods for their structure were made from laser-cut wood. The focus was much more on community and sharing designs freely to improve the quality of the printers as rapidly as possibly while still using parts easily purchased from a hardware store or on-line. Many of the commercial 3D printer offerings at the time also were some form of a RepRap printer sold pre-assembled and calibrated with some refinements and improvements, plus support from the company if anything went wrong.

  • Webinar on real-time IoT data analytics, visualization and collection with open-source Kaa IoT, Apache Cassandra and Apache Zeppelin

    In the course of the webinar we will set up an end-to-end solution comprising Kaa, Apache Cassandra and Apache Zeppelin to demonstrate their cumulative capabilities for collecting, analyzing and visualizing large sets of data in real time.

  • Microservices served on blockchain, in open source
    Cloud application marketplace company Wireline is working with open source blockchain project developer Qtum The new union is intended to provide a conduit to consuming microservices at [web] scale using blockchain at the core. As we know, microservices offer the ability to create Application Programming Interfaces (APIs) without having to manage the underlying hardware and software infrastructure. [...] The Qtum a blockchain application platform combines the functions of Bitcoin Core, an account abstraction layer allowing for multiple virtual machines and a proof-of-stake consensus protocol aimed at tackling industry-use cases. The Qtum Foundation, headquartered in Singapore, is the decision-making body that drives the project’s development.

    A few days back I wrote about Intel's work on Control-flow Enforcement Technology beginning to land in GCC. This "CET" work for future Intel CPUs has now landed in full for GCC 8. The bits wiring up this control-flow instrumentation and enforcement support are now all present in mainline GCC SVN/Git for next year's GCC 8.1 release.

    After having moved from FSFE’s wordpress instance I thought long about whether I still want to have comments on the new blog. And how I would be able to do it with a statically generated site. I think I have found/created a pretty good solution that I document below.

  • Where Did That Software Come From?
    The article explores how cryptography, especially hashing and code signing, can be use to establish the source and integrity. It examines how source code control systems and automated build systems are a key part of the software provenance story. (Provenance means “a record of ownership of a work of art or an antique, used as a guide to authenticity or quality.” It is increasingly being applied to software.)

  • NVIDIA TX2 / Tegra186 Display Support Isn't Ready For Linux 4.15
    While the Jetson TX2 has been out since this past March and it's a phenomenal ARM development board, sadly the Direct Rendering Manager (DRM) driver support for it still isn't ready with the mainline Linux kernel. Thierry Reding of NVIDIA sent in the Tegra DRM driver changes for DRM-Next that in turn is staged for Linux 4.15. Reding commented that there is prepatory work for the TX2 (Tegra186) but it's not all ready for upstream yet.
