  • Painting robot with ‘twin’ control scheme

    For a class project, University of Stuttgart students Ekin Sila Sahin, Lior Skoury, and Simon Treml came up with a unique painting robot named the Physical Twin.

    The Physical Twin travels on a three-wheeled chassis and mounts a four-axis arm with a brush. An operator controls the arm to dip the brush into an onboard paint container, and can then manipulate it for application.

  • Open Up: Benefits of Open Source Firmware

    Firmware is a set of programs inside most electronic equipment responsible for performing its basic functions. It’s similar to the parts of the brain in charge of involuntary functions, which tell your lungs when to breathe and your heart when to beat.

    When you turn on your computer, for example, your firmware directs power to every component, and then works in conjunction with your software kernel to boot into your operating system. Firmware is generally accompanied by a firmware menu, where you can change settings for these basic functions, choose boot drives, and more.

    Almost everything here at System76 is under the GNU GPL, or GNU General Public License, including our firmware. This means you can adapt it, modify it, learn from it, and redistribute it with the condition that the benefits are also offered to the original developer (in this case, us). There is an inherent shared collective progress built into the license. Powerful thrust lifts all rockets. (As a note, when something we create isn’t under the GNU GPL, that just means it’s under an even more permissive license that allows the code to be used in any way without contributing changes upstream.)

  • EU probe asks if Apple, Amazon, and other giants are stifling the Internet of Things

    The European Union’s antitrust watchdog is investigating whether Apple, Google, Amazon, or other companies are building monopolies with their digital assistants and smart home products. EU Competition Commissioner Margrethe Vestager announced a probe into the Internet of Things sector, aimed at making sure users aren’t locked into a single ecosystem. “When big companies abuse their power, they can very quickly push markets beyond the tipping point, where competition turns to monopoly,” said Vestager in a statement.

    Vestager raised concerns about products like Amazon’s Alexa assistant, which ties together the company’s vast retail, hardware, and data collection operations. “Voice assistants and smart devices can collect a vast amount of data about our habits. And there’s a risk that big companies could misuse the data collected through such devices,” she said. While the biggest targets appear to be Silicon Valley tech companies, Vestager also mentioned Deutsche Telekom’s Magenta voice assistant.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
