  • Rocket League for Linux: The Definitive Video Review

    Rocket League blasted on to Linux at the end of last week and we were ridiculously about it — but perhaps you're not caught up in the excitement.

  • Last Minute Wayland Fixes For GNOME 3.22

    It looks like running the GNOME desktop environment natively on Wayland should be in pretty good shape after a round of last-minute improvements.

    GNOME 3.22 package updates this week provided a number of important Wayland fixes:

    Mutter 3.21.92 fixes for Wayland: absolute pointer motion events, animated cursors, various crashes, XWayland pointer warp emulation, and other non-Wayland improvements.

  • Who Needs the Internet of Things?

    This week, the Raspberry Pi Foundation announced it has sold more than 10 million Raspberry Pi boards and celebrated the milestone by releasing a new Raspberry Pi Starter Kit. While many of these Linux-driven hacker boards were used for the foundation’s original purpose -- creating a low-cost computer for computer education -- a large percentage have been sold to hobbyists and commercial developers working on Internet of Things (IoT) projects ranging from home automation to industrial sensor networks.

    Linux-driven open source and commercial single board computers and modules sit at the heart of the IoT phenomenon. They are usually found in the form of gateways or hubs that aggregate sensor data from typically wirelessly enabled, sensor-equipped endpoints. Sometimes these endpoints run Linux as well, but these are more often simpler, lower-power MCU-driven devices such as Arduino-based devices. Linux and Windows run the show in the newly IoT-savvy cloud platforms that are emerging to monitor systems and analyze data fed from the gateways in so-called fog ecosystems.

    Over the next few weeks, I’ll be analyzing the IoT universe, with a special focus on Linux and other open source technologies used in home and industrial automation. I’ll look at major open source products and projects, IoT-oriented hacker boards, security and privacy issues, and future trends.

  • Taunton’s open source success: a new era for electronic patient records

    Almost one year ago our organisation, Taunton and Somerset NHS FT, achieved an important milestone in delivering transformational change in our digital programme: we became the first NHS trust to go live with an open source electronic patient record (EPR).

    Some may have perceived this as a risky choice. An open source EPR was untested within the NHS, and NHS organisations can tend to do what everyone else has already tried. Yet we saw that, by having a flexible system that had no licence fees, we would be able to tailor the system as we went along, to suit the needs of our clinicians, patients and our healthcare partners in Somerset.

  • Navigating the challenges of international teamwork

    OpenEMR, OpenMRS, and VisTA are three of the most well-known open source applications in the health IT genre. OpenEMR has worldwide acceptance as a complete and flexible electronic healthcare records (EHR) system that can be tweaked with relative ease to work anywhere. That is evident in its adoption by the International Planned Parenthood Foundation, the Peace Corps, and most recently by the Health Services Dept of Israel. OpenMRS is a respected tool set and API that has been predominantly used in Africa, and has been adopted for targeted healthcare needs all over the world. Despite being a US-based project, its adoption in the US is minimal. VisTA is the US Veteran's Administration EHR and it is now, due mainly to the formation of OSEHRA.org, beginning to get traction in other countries as a solution to the high cost of proprietary EHR systems for hospitals. New on the horizon are projects like FHIR, started in Australia, and adopted by hl7.org.

  • Infostretch Adds New Open Source Test Automation Framework to QMetry Suite
  • Udacity plans to build its own open-source self-driving car

    Sebastian Thrun’s online education startup Udacity recently created a self-driving car engineering nanodegree, and on stage at Disrupt today Thrun revealed that the company intends to build its own self-driving car as part of the program, and that it also intends to open source the technology that results, so that “anyone” can try to build their own self-driving vehicle, according to Thrun.

    The crowdsourced vehicle plans will ultimately be created in service of the school, rather than a product in and of itself. The open-sourcing of the data should help other projects ramp up, and will include driving data and more to contribute to other people’s projects.

  • Q&A: SFU alumna launching new "open source" food co-op

    SFU alumna Jennifer Zickerman is making it easier to access locally grown, high quality herbs through her venture, the Lower Mainland Herb Growers Co-op.

    The co-operative offers economy of scale to local small growers growing culinary herbs. It will buy fresh herbs from local growers, then dry and package them as culinary herb blends and distribute them to retail stores.

    Zickerman first developed this business idea as a student in SFU's Community Economic Development (CED) program. She pitched it as part of the program's annual Social Innovation Challenge, winning $12,000 to implement her idea.

    The co-op's high quality products aim to replace the poor quality dried herbs found in most retail stores that are imported from countries with poor environmental and labour standards.

    Local farmers will also have a new market for a crop that grows well in this climate and requires few artificial supports such as fertilizer, pesticides and greenhouses.

  • Chile's green energy future is powered by open data analysis

    Open source software and open data play key roles in implementing Chile's long-term energy planning, identifying ways to get the maximum value from development, minimizing its impact, and requiring less development overall.

    Over the past two years, our company—in partnership with the Centro UC Cambio Global of the Pontificia Universidad Católica de Chile—has been designing, building, and testing a framework to support Chile's Ministry of Energy in policy evaluation and regional hydroelectric power planning activities. Open source software and open data play a key role in this framework, but before I explain how, I need to summarize the context.

  • DYNAcity project starts mobility pilot in Flemish City of Ghent

  • How to help developers help themselves

    Developers need help. It comes with the territory for software companies employing thousands of developers, many who live and work in remote locations all over the world. At Red Hat, Rafael Benevides doles out lots of help. He teaches developers about tools and practices so they can be more productive, and he'll be taking the show on the road for the tech conference All Things Open this year where he'll share his specfic thoughts on cloud development.

  • Adblock Plus finds the end-game of its business model: Selling ads

    Eyeo GmbH, the company that makes the popular Adblock Plus software, will today start selling the very thing many of its users hate—advertisements. Today, the company is launching a self-service platform to sell "pre-whitelisted" ads that meet its "acceptable ads" criteria. The new system will let online publishers drag and drop advertisements that meet Eyeo's expectations for size and labeling.

    "The Acceptable Ads Platform helps publishers who want to show an alternative, nonintrusive ad experience to users with ad blockers by providing them with a tool that lets them implement Acceptable Ads themselves,” said Till Faida, co-founder of Adblock Plus.

    Publishers who place the ads will do so knowing that they won't be blocked by most of the 100 million Adblock Plus users. The software extension's default setting allows for "acceptable ads" to be shown, and more than 90 percent of its users don't change that default setting.

    Eyeo started its "acceptable ads" program in 2011. With the new platform, it hopes to automate and scale up a process that until now has been a cumbersome negotiation. What once could take weeks, the company boasts in today's statement, now "takes only seconds."

  • 5 Ways The Modern World Is Shockingly Ready To Collapse

    As technology embraces the digital, abandoning the crude and primitive notion of "physical existence" entirely, the idea that you actually own the media you buy is vanishing faster than that goddamn Walkman you swore was in the closet. And it's more than inconvenient for consumers; it may be apocalyptic for our society.

    [...]

    If you tried to purchase an Adobe product recently, you're already aware of this trend. As of 2013, you can no longer buy programs such as Photoshop, Flash, or Dreamweaver. You can only "subscribe" to them for a monthly fee. Yes, now you have the privilege of paying for your software forever. Isn't the future wonderful?

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
