  • Mythic Licenses Codasip's L30 RISC-V Core for Next-Generation AI Processor

    Codasip, the leading supplier of customizable RISC-V® embedded processor IP, announced today that Mythic, the pioneering AI processor company with breakthrough analog compute-in-memory technology, has selected Codasip’s L30 (originally Bk3) RISC‑V‑based core for Mythic’s next generation Analog Matrix Processor (Mythic AMP™).

  • This lamp consists of 122 LED-lit domes on a sphere, controllable over Bluetooth | Arduino Blog

    There are already countless projects that utilize individually addressable RGB LED strips in some way or another, except most of them lack a “wow” factor. This is one problem that Philipp Niedermayer’s Sphere2 Lamp does not suffer from, as it is a giant sphere comprised of 122 smaller domes (cut ping pong balls) that are each lit by their own LED. The project uses an Arduino Nano running code with the FastLED library to output signals via its GPIO pins to the LEDs. It is controlled over its serial interface by a Nano 33 BLE Sense since the latter has integrated BLE functionality.

  • Arduino-based control panel streamlines laser cutting | Arduino Blog

    Laser cutters require quite a lot of power and laser tubes need active water cooling, which means you need a coolant reservoir and a water pump. You also need an exhaust fan to remove smoke, which will reduce the laser’s efficacy. Add in a computer, positioning laser, etc., and you’ve got quite a lot to control. That’s why Kaleb Clark used an Arduino to create a control panel for his laser cutter.

    This control panel provides several toggles switches, which Clark can flip to turn on the water pump, the air assist, and so on. Each switch has a corresponding WS2812B individually-addressable RGB LED indicator light. There are also status lights that tell him if the air pressure and water flow are in the correct range. Instead of messing around with extension cords and outlets, he can flip all the switches in sequence and then start cutting. When the job finishes, he can flip them all back off.

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.
