  • Art-Pi STM32H750 Cortex-M7 board supports RT-Thread, mainline Linux

    I like to browse Linux changelog to learning about new features in the kernel, but also new hardware that made it into mainline Linux, even if only preliminary or partial.

  • Ugoos AM6B Plus 2021 TV box adds WiFi 6 connectivity

    Ugoos AM6B Plus 2021 is an update to last year’s Ugoos AM6 Plus Android 9.0 TV box with Dolby Vision support through Amlogic S922X-J hexa-core processor. What has changed exactly? A WiFi 6 & Bluetooth 5.0 LE module replaces the WiFi 5 & Bluetooth 5.0 LE module used on the previous model.

    The new WiFi 6 TV box still comes with 4GB RAM, 32GB eMMC flash, Gigabit Ethernet, 4K video support through an HDMI 2.1 port, and VPU capable of 4Kp60 H.265, H.264, and VP9 video decoding.

  • DIY radar speed sign looks and works like the real thing | Arduino Blog

    Those large, white speed signs you encounter alongside the road while driving can be annoying, as inattentive drivers slam their brakes right in front of you. However, the underlying technology that powers them is quite cool, which is why John McNelly wanted to construct his own DIY version that closely reflects the actual one.

    McNelly’s design relies on an Arduino Nano and a Doppler radar module that sends out 10.525GHz radio pulses continuously and measures how much the reflected frequency has changed. Thinking back to that one high school physics class, you probably learned that as an object approaches, the reflected frequency will increase, whereas the frequency will decrease as the object gets further away. Using the Doppler effect, speed can be determined by subtracting the frequency coming from a custom pre-amplifier from the original signal.

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.
