  • Arduino Mbed Core for RP2040 boards | Arduino Blog

    Arduino support for the Raspberry Pi RP2040 chip is available now using the official Arduino Mbed Core. This is obviously very important, and exciting, for the upcoming Arduino Nano RP2040 Connect. But it goes beyond the Arduino device to also bring support to other boards built around the RP2040 chip.

  • Playing Connect Four against a mini golfing AI opponent | Arduino Blog

    Have you dreamed of combining the two incredible activities putt-putt and Connect Four together into the same game? Well one daring maker set out to do just that. Bithead’s innovative design involves a mini golf surface with seven holes at the end corresponding to the columns. The system can keep track of where each golf ball is with an array of 42 color sensors that are each connected to one of seven I2C multiplexers, all leading to a single Arduino Uno.

    The player can select from six distinct levels of AI, all the way from random shots in the dark to Q Learning, which records previous game-winning moves to improve how it plays over time. It can putt by first loading a golf ball into a chamber and then spinning up a pair of high-RPM motors that launch it. For the human player, there is a pair of dispensers on the left that give the correct color of ball.

  • SGET OSM (Open Standard Module) compliant SoM features NXP i.MX 8M Mini SoC - CNX Software

    The company provides supports for Buildroot & Yocto to build a custom Linux image running on the Cortex-A53 core(s) and FreeRTOS for the Cortex-M4 microcontroller. The module will be available until 2029.

  • SiFive Intelligence X280 64-bit RISC-V processor integrates AI extensions - CNX Software

    The last RISC-V core announced by SiFive was the U8-Series out-of-order RISC-V Core IP that aims to compete against Arm Cortex-A72 Core. But in their latest announcement, the company built upon the 64-bit RISC-V U7-series with the SiFive Intelligence X280 multi-core, Linux capable RISC-V processor adding vector extensions and SiFive Intelligence Extensions, and optimized for AI/ML compute at the edge.

    [...]

    SiFive further explains that in addition to ML inferencing, the new Intelligence X280 core is also suited for applications requiring high-throughput, single-thread performance while under power constraints citing AR/VR, sensor hubs, IVI systems, IP cameras, digital cameras, and gaming devices as examples.

    The first customer integrating the RISC-V core into their design will be Tenstorrent, a company that provides AI training and inference processors. More details may be found on the product page and press release.

  • Arm Outlines More Neoverse N2 + Neoverse V1 Platform Details

    Arm published today a set of blog posts outlining more power/performance and feature details of their forthcoming Neoverse N2 and Neoverse V1 platforms.

    As announced last September, Arm's Neoverse V1 platform is for delivering the highest performance from any Arm-designed core. The Neoverse V1 while based on the N1 has a "radical redesign of the CPU microarchitecture". The Neoverse V1 platform supports multi-chiplet and multi-socket solutions and can support DDR5/HBM3 memory, PCI Express 5.0, and CXL 2.0 attached memory and coherent accelerators.

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.
