  • Pi HAT brings Time-Sensitive Networking (TSN) to Raspberry Pi 4

    InnoRoute has launched its “Real-Time HAT,” a HAT for Raspberry Pi 4 that enables support for TSN and other real-time protocols. The Artix-7 FPGA-based HAT supports TSN and PoE through its 3 GbE ports.

    InnoRoute has rolled out the Real-Time HAT, a HAT that brings Time-Sensitive Networking (TSN) capability to the Raspberry Pi 4. At the heart of the Real-Time HAT’s functionality is a Xilinx Artix-7 FPGA and three Analog Devices ADIN13007 Gbit Ethernet transceiver PHY chips. The HAT enables precise network timing for real time protocols such as TSN and others. It can do synchronization between HATs, over the network, or with external GPS PPS. Its connectors are set up so that additional HATs can be attached on top of the Real-Time HAT.

  • $18 Tang Nano 4K FPGA board comes with HDMI output, optional camera - CNX Software

    Sipeed’s Tang Nano 4K FPGA board is an upgrade to the company’s Tang Nano FPGA board with a more powerful GOWIN GW1NSR-LV4C FPGA with 4608 LUT (instead of 1152) and a Cortex-M3 microcontroller embedded into the chip.

    Like the previous board, the new Tang Nano 4K features a USB-C port for power and downloading the bitstream, but replace the RGB LCD interface with an HDMI port, and adds support for an optional OV2640 camera.

  • Keep tabs on your daily runs with this interactive tracker | Arduino Blog

    Being able to keep oneself accountable while working out is a vital component to almost any good exercise plan, since repetition is the key to success. In response to their significant other wanting a way to track their workouts throughout the week, Instructables user smooth_jamie set out to build a highly interactive device that gives the person using it motivation to continue on after accomplishing the day’s goal.

    The project largely consists of a large rectangular enclosure, which houses a series of seven 128×32 OLED screens, along with a single push button next to each one. Just across from the displays is a string of WS2812B LEDs that correspond to that day’s achievement or lack thereof. Jamie had run into the issue of the OLEDs having hardcoded I2C address, so they were forced to use an I2C multiplexer breakout. They also wanted for the device to play a short song to really commemorate meeting that day’s goal, so a speaker and amplifier circuit was added onto the Arduino Mega.

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.
