  • AI box PC combines a 10th Gen CPU, dual 2.5GbE and dual PCIe for medical analytics

    IEI’s Linux-ready “HTB-210-Q470 AI Box PC” runs on Comet Lake-S and supplies up to 128GB DDR4, 2x 2.5GbE, M.2 A- and M-key, and PCIe x4 and x16 for Nvidia Tesla T4. Intel plans to phase out Comet Lake-S in 2022.

    IEI announced an edge AI desktop computer based on Intel’s 10th Gen Comet Lake-S. The HTB-210-Q470 “AI Box PC” is especially suitable for medical analytics due to its support for Nvidia Tesla T4 graphics cards, as well as its ease of cleaning and white, streamlined, medical appliance design.

  • PneuMod is a wearable haptic device that produce pressure and thermal feedback | Arduino Blog

    When trying to imagine a new way of interacting with either a video game or even another person remotely, being able to feel both temperature and touch sensations isn’t what most people would have in mind. However, thanks to some very interesting research being done by University of California, Santa Barbara student Bowen Zhang and professor Misha Sra, a novel method for interacting with the virtual world could come quite soon.

    The project, which Zhang calls the “PneuMod,” is a modular system of tiny air bladders that each have a Peltier element on their surface. Then using an Arduino Mega and a custom-designed control board, commands can be sent from a laptop that open or close solenoid valves to let air inflate/deflate the air bladders, thus creating pressure against the wearer’s skin. Different temperatures are safely produced by combining the Peltier elements with temperature sensors, and by adjusting the polarity of the current headed to these elements, both hot and cold can be achieved with the exact same hardware.

  • An Open Source Detector For Identifying Plastics | Hackaday

    One of the challenges involved in recycling plastic is determining the specific type of plastic a given item is actually made of. To keep up with demand, large scale recycling centers rely on various automated systems to separate different types of plastic from a stream of incoming material. But in less technologically advanced parts of the world, workers can find themselves having to manually identify plastic objects; a time consuming and error-prone process.

    To try and improve on the situation, [Jerry de Vos], [Armin Straller], and [Jure Vidmar] have been working on a handheld open hardware device that they refer to simply enough as the Plastic Scanner. The hope is that their pocket-sized unit could be used in the field to positively identify various types of plastic by measuring its reflectivity to infrared light. The device promises to be very easy to operate, as users simply need to bring the device close to a piece of plastic, push the button, and wait for the information to pop up on the OLED display.

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.
