  • MutantC V4 - DIY Raspberry Pi Handheld PC adds ESP32-S2 module - CNX Software

    Earlier this year we wrote about Mutantc V3 DIY Raspberry PI UMPC after noticing a talk about it at FOSDEM 2021 online conference. MutantC V4 is a new version of the Raspberry Pi handheld PC that is both easier to build and cheaper.

    The new model replaces the Arduino Pro Micro board with a more compact ESP32-S2 module and offers a Lite version with even fewer parts (notification LED, IR blaster, IMU, etc..) to make it easier to build.

  • T-Watch 2021 ESP32 round smartwatch features ESP32 SoC, touchscreen, 500mAh battery - CNX Software

    Back in May, LilyGo started selling “Paul’s 3D Things” Open-Smartwatch open-source hardware ESP32 watch as a kit with the board and a round display, but no case, wristband, or battery, although now a smartwatch kit, but still without battery, is available for around $30.

    The company has now designed the T-Watch 2021 which builds upon the Open-Smartwatch but adds features like a touchscreen display, a vibration motor, a magnetometer, and ships as a devkit with board and display or a complete smartwatch kit including a 500mAh battery.

  • Trakcore is a Nano 33 IoT-based posture correction device | Arduino Blog

    Poor posture is an epidemic for nearly anyone who spends an excessive amount of time sitting, and this can lead to a whole host of problems later in life. Some of these might include back pain, limited range of motion, and muscle tightness. Recognizing that his own posture was lacking, element14 user vlasov01 got to work designing and constructing a small wearable device for element14 Design for a Cause 2021 contest, which could help him alter his posture throughout the day to a more correct one. This project was dubbed the Trakcore, and it uses the sensors on the Arduino Nano 33 IoT to sense how a person is sitting or standing and then sends an alert when it needs adjustment.

  • Sustainable transformation of agriculture with the Internet of Things

    With the urgency to prevent environmental degradation, reduce waste and increase profitability, farmers around the globe are increasingly opting for more efficient crop management solutions supported by optimization and controlling technologies derived from the Industrial Internet of Things (IIoT).

    Intelligent information and communication technologies (IICT) (machine Learning (ML), AI, IoT, cloud-based analytics, actuators, and sensors) are being implemented to achieve higher control of spatial and temporal variabilities with the aid of satellite remote sensing. The use and application of this set of related technologies are known as “Smart Agriculture.”

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.
