  • What Is PWM in Arduino

    Pulse width modulation (PWM) is a widely-used concept in physics, electronics and telecommunications. It is defined as a form of signal modulation to derive analog waveforms from digital inputs.

    In Arduino applications, PWM is useful in varying the intensity of a signal such as the brightness of an LED diode, the ping time of sensors or the power delivery of servomotors.

  • RISC-V Bases and Extensions Explained

    The other day we reported about GigaDevice GD32V general-purpose 32-bit RISC-V microcontroller, and one of the commenters asked whether it was rv32imac or rv32emac..

  • Innocomm Unveils MediaTek i300/i500 SoMs for IoT and AI Applications

    Just announced by Innocomm are the SB30 and the SB50 SoMs carrying the MediaTek i300 and i500 SoC’s, and running either Linux or Android. The rundown on the systems is the MediaTek AIoT processor series has been out for some time, and we reported on the latest SoC in the MediaTek i700 article last July.

  • Logic Supply Announces Karbon 700 Rugged Linux PC With Core / Xeon CPU Options

    Earlier this summer we checked out the Logic Supply Karbon 300 as a well-built and very durable Linux-friendly PC for low-power environments. That Karbon 300 came equipped with a low-power Apollo Lake Atom processor while today the company announced the Karbon 700 with higher-wattage Core and Xeon CPU options for high performance IoT / edge computing.

    The Karbon 700 series is built similarly well to the Karbon 300 series and a similar (but slightly larger) form factor while now being able to handle 35 Watt / 65 Watt Core CPUs or up to 80 Watt Xeon E "Coffeelake" processors.

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.
