  • Spaghetti Detective: Open Source AI Software Detects Prints Gone Wrong

    Desktop 3D printer users are quite familiar with the mishaps of some print job going wrong and extruders spilling material all over their machine while they’re out at the store or soundly sleeping in bed. Being confronted with a printer full of plastic spaghetti when you next go to check on it is one of the most disheartening and frustrating experiences a user can face.

    Attempting to address this issue is the Spaghetti Detective (TSD), a piece of open source artificial intelligence software that automatically interrupts failed prints. The software runs continuously on a computer server and uses a computer or printer’s webcam to monitor the printing process. If it detects a print failure, it automatically pauses the print and alerts the user via text or email. You can then choose to cancel the print and prevent not only a plate of inedible spaghetti from forming, but also the possibility of equipment damage or fire hazard. The Spaghetti Detective can run on an old PC connected to the web or, if you prefer not to rely on the cloud, it’s possible to host the TSD server on a Jetson Nano card from NVIDIA.

  • Open Source Telescope Controller Puts Smart Features In Old Telescopes

    In times like these, we all need to look beyond ourselves. This project might help: OnStep is an open-source telescope controller, a device that controls a telescope to point at something interesting in the sky. Want to take a look at M31? Use an app on a PC or smartphone, select the object and the OnStep will pan and tilt your telescope until the Andromeda Galaxy pops into view.

    [...]

    It is pretty hardware agnostic: the controller can be an Arduino, a Teensy 3 or even an ESP32. The PCB design can work with any of these controllers. The same is true of the motors that move the telescope, so you can build the device from parts that you might have lying around. Many of those who have built OnStep controllers have adapted older telescope mounts that are motorized but aren’t smart. Others have used older mounts and replaced the slow, inaccurate motors with more precise ones that make the telescope more accurate and smooth. The gallery of telescope builds on the OnStep wiki is a great place to start and see examples like this 30-year old Celestron telescope that was brought into the 21st century with a OnStep conversion, or this conversion of a 1960s telescope that adds a smart mount.

  • BSC-Led DRAC Project to Manufacture New Chip, Open Source Accelerators in Barcelona

    If Lagarto, the first open source processor developed in Spain and Mexico, was introduced in December, now DRAC is presented. It is a project to develop a new processor and several open source accelerators. DRAC (Designing RISC-V-based Accelerators for next generation Computers) is a new step in research led by the Barcelona Supercomputing Center (BSC) to manufacture open source chips from Europe. The project has the collaboration of the Polytechnic University of Catalonia (UPC), the University of Barcelona (UB), the Autonomous University of Barcelona (UAB) and the Rovira i Virgili University (URV).

    The objective of DRAC is to manufacture a processor and several accelerators to be used in security tasks (encryption or protection from attacks against hardware, for example), personalized medicine (especially genomic analysis) and autonomous navigation (cars and other vehicles).

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.
