  • 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 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 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.

How to improve tech skills while contributing to open source projects

Filed under

Although some people think open source projects only need programmers—and experienced ones, at that— open source project needs go beyond the ability to write code. They also require testing, technical support, documentation, marketing, and more. And contributing to projects also is a great way to improve technical skills and connect with people who share similar interests. One barrier to participating in open source projects is not knowing how to join and get started. In this article, I'll explain how to start contributing to an open source project.

  • Snark attack: Cornell students teach software to detect sarcasm!

    A team of students participating in Cornell University's Tech Challenge program has developed a machine learning application that attempts to break the final frontier in language processing—identifying sarcasm. This could change everything… maybe.

    TrueRatr, a collaboration between Cornell Tech and Bloomberg, is intended to screen out sarcasm in product reviews. But the technology has been open sourced (and posted to GitHub) so that others can modify it to deal with other types of text-based eye-rolling.

  • How Thalmic Labs’ open source approach helped a man regain use of his arm

    When Thalmic Labs made the decision to go open source with its Myo arm band, it probably never imagined that doing so would lead to an amputee regaining the use of a limb.

    Thanks to the work of Johns Hopkins Medical School, Johnny Matheny has become the first person to attach a gesture-controlled limb directly to his skeleton, and it’s controlled with the Myo arm band. The delivery driver lost the lower part of his left arm to cancer in 2008. Late last year, Johns Hopkins designed a Modular Prosthetic Limb and used Myo’s electromyography (EMG) sensors to measure the electrical signals sent from Matheny’s upper arm to control his lower arm. Those signals are converted into Bluetooth transmissions to a controlling computer mounted on the prosthetic, which then determines the motion to be made with the limb.

  • Open-source GPU could push computing power to the next level

    Binghamton University computer science assistant professor Timothy Miller, Aaron Carpenter and graduate student Philip Dexterm, along with co-author Jeff Bush, have developed Nyami, a synthesizable graphics processor unit (GPU) architectural model for general-purpose and graphics-specific workloads. This marks the first time a team has taken an open-source GPU design and run a series of experiments on it to see how different hardware and software configurations would affect the circuit's performance.

  • Open-Source Arduino DIY Thermographic Camera From €450

    Developers and makers that are interested in making their very own open source Thermographic camera might be interested in a site called Thermocam that provides all the knowledge, instructions and components you need to do just that.

    The site also seems everything you need to make the camera from the Thermal sensor and board to the mini tripod that can be used to position the camera when finished.

    A fully working Thermographic Camera can be used for a variety of applications including finding heat leaks in the insulation of buildings, analysis of electrical or mechanical components and more. The project is Arduino compatible and the firmware is adaptable to your needs.

New open-source ad-blocking web browser emerges from brain of ex-Mozilla boss Eich

Filed under

A new open-source browser that blocks ads and tracking code and so promises to "fix the Web" by offering a faster, privacy-respecting experience has been released.

The Brave browser is the brainchild of former Mozilla (Firefox) CEO and JavaScript inventor Brendan Eich, and version 0.7 is now available to developers on GitHub.

Brave is built on top of open-source browser Chromium – which Google uses as the foundation for its Chrome browser – and claims to be between 1.5 and 4 times faster than competitors by stripping out not just ads, but also all the tracking code that lives in abundance on most ad-supported websites.

Contribute to open source! It’ll look great on your resume! It’s gratifying work!

You may have heard people make these statements, or ones similar to them, numerous times throughout your career. They’re not wrong—contributing to open source is a rewarding endeavor in multiple dimensions—but, when software engineers advise other software engineers to contribute to open source they usually mean code contributions. This is a fair assumption to make, but the reality is that there are numerous opportunities to contribute to open source without writing a single line of code.

7 Truths that Open Source Struggles With

Filed under

Open source development has consistently proved many ideas that were once considered impossible. For instance, thanks to open source, we now know that people can be motivated by more than money, and that co-operation can be more effective in some aspects of development than competition.

Personally, I get a lot of self-satisfied glee each time that open source undermines yet another “fact” that everyone knows.

However, just because open source has consistently confounded common expectations does not mean that it is always right. There are at least seven assumptions that many in open source continue to believe, often in the face of overwhelming evidence to the contrary:

The Licensing and Compliance Lab interviews AJ Jordon of

So basically Bradley Kuhn gave a talk at FOSDEM '17 about GPL enforcement and I was like, wow, it sucks how many companies and people think that enforcing the GPL is a bad idea. I mean, if you disagree with copyleft that's fine (though I personally would argue with that position), but then you should use a suitable license. Like MIT. The very idea that we shouldn't enforce the GPL just doesn't make sense to me because it suggests that the text of the license is watery and unimportant. I don't know about you, but when I say I want my programs to respect users' freedom, I mean it. So GPL enforcement is important. It seemed to me that there are probably a lot of developers out there who want to support GPL enforcement but don't have a good way to voice that support. is essentially a quick and dirty hack I wrote to make that dead-simple.
