  • NXP i.MX RT500 Cortex-M33 Crossover MCU integrates DSP, 2D GPU for wearables and IoT devices - CNX Software

    NXP i.MX RT500 is the second Cortex-M33 Crossover MCU following the NXP i.MX RT600 Series announced in 2018, and optimized for low-power HMI applications such as wearables and Smart Home & IoT devices.

    NXP Crossover MCUs are typically clocked at 600 MHz or more, but NXP i.MX RT500 Cortex-M33 is limited to 200 MHz, and combined with 200 MHz Tensilica Fusion F1 DSP as well as a 2D GPU, and power optimizations that enable long battery life of up to 40 days on a charge for wearables like smartwatches.

  • Raspberry Pi based Pi-KVM goes to Kickstarter

    A year after the first release, Raspberry Pi based Pi-KVM presented its own hardware on Kickstarter.

    Pi-KVM is a software and instructions project that turns a Raspberry Pi into a fully functional IP-KVM. This device connects to the HDMI and USB ports of the server, and allows it to be controlled remotely over the network, regardless of the operating system. You can turn on, turn off or reboot the server, configure the BIOS, and even completely reinstall the OS from an image on emulated virtual media. All functionality (including video transmission) is available through a web interface that does not require any additional plugins and applets, and is implemented only using HTML5 tools.

  • Meet Roamer, a companion robot that charges itself | Arduino Blog

    Tiny mobile robots are a blast to use. They are fast, fun, and can even be autonomous. However, they all suffer from a similar issue: batteries, which are notorious for running out of charge quickly when the motors are kept spinning for too long. To address this issue, Mike Rigsby came up with a small robot that has a simple “brain” but has the ability to never run out of power.

    Rigsby’s robot, named Roamer, starts off on a charging station that is comprised of a large metal plate on the bottom and a small, energized bump rail. The bot contains a spring under its base that contacts the plate, and its front plate contacts the bumper. Therefore, when the two meet, the circuit is completed, and Roamer can determine if it needs to charge.

  • 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.
