  • KloudNote 10.3-inch E-reader supports WiFi, Bluetooth and cellular connectivity - CNX Software

    Geniatech used to be better known for their Amlogic TV boxes, before expanding their business to development boards and systems-on-modules. But the company has now introduced KloudNote, a 10.3-inch E-reader running Android 8.1 on a quad-core Cortex-A35 processor.

    The device is equipped with 2GB of RAM and a 16GB eMMC flash, supports WiFi 5 and Bluetooth, as well as optional 2G/3G/4G LTE cellular connectivity, and comes with a USB-C port and a headphone jack.

  • TI AM64x 7-core processor is made for PLC's, motor drives, industrial robots - CNX Software

    Texas Instruments AM64x is a family of 64-bit Arm processors with functional safety designed for Programmable Logic Controllers (PLC), motor drives, remote I/O, and industrial robots. The top-end processor of the family, AM6442, comes with seven cores including two Cortex-A53 application cores, four Cortex-R5F real-time cores, and one Cortex-M4F isolated core.

    AFAICT, while the documentation is dated January 2021 and TI announced the processor in February in a blog post with a cryptic title, it was only first picked up by Embedded Computing in early May. Besides the processor itself, TI also provides an AM64x starter kit and a full-featured AM64x evaluation kit, and several companies are already preparing development boards and modules as we’ll see further below.

  • 14 Awesome Arduino Cloud Features You Never Knew Existed

    There are dozens, if not hundreds of amazing Arduino Cloud features. So it’s perfectly understandable if you’ve missed some of them.

    So we’ve put together a list of our favorite Arduino Cloud features that you might not know existed.

  • Homemade mechanical color TV runs on an Arduino Due | Arduino Blog

    Nearly everyone alive today has never the technical marvel that is the mechanical television. In short, the work by quickly strobing a light through a disc that has holes cut around its perimeter, with each hole being slightly lower than its predecessor. Combined with the persistence of vision effect, this gives the illusion of a still image with its number of rows being equal to the number of holes in the disc. YouTuber “Science ‘n’ Stuff” wanted to try creating a modern version that uses a microcontroller to precisely adjust an LED’s color, rather than using an analog signal.

    The device has a single large plastic disc with 32 holes for a total of 32 rows in the image. It’s spun at 1500 RPM by a DC motor that’s driven via PWM, and because there can be some variance in the motor’s speed, the synchronization signal that’s produced on each full rotation is also used to carefully adjust the motor’s speed to keep it constant. Both images and sound are read from an onboard microSD card, with the images being converted into pulses of light and the sound being played on a mono speaker. All of this is controlled by an Arduino Due board.

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.
