  • Sipeed Lichee RV RISC-V module gets $5+ carrier board with HDMI and USB ports, optional WiFi - CNX Software

    Sipeed introduced the Lichee RV Allwinner D1 Linux RISC-V board going for just $17 with 512MB RAM last month. While with a USB-C port it could be used as a standalone part, its dual M.2 connector makes it more like a module and we noted a tiny carrier board was in the works at the time.

    The baseboard is now available and known as the Lichee RV Dock adding HDMI and USB ports, as well as a 40-pin GPIO header for just $5, or $8 if you’d like to get Wi-Fi 4 and Bluetooth 4.2 connectivity through a Realtek RTL8723DS module.

  • CH583 RISC-V microcontroller supports Bluetooth 5.3 LE - CNX Software

    Following up on the CH572 RISC-V BLE microcontroller with 10KB SRAM, WCH has now introduced the CH583 RISC-V microcontroller with 32KB SRAM, 1 MB flash, and support for the latest Bluetooth 5.3 LE standard.

    The new microcontroller also offers a wide range of peripherals with two USB host/device interfaces, up to 40 GPIOs, four UART, two SPI, one I2C, up to 14 ADC interfaces, and more. WCH also offers CH581 and CH582 microcontrollers with a different minimum input voltage, less storage (256KB for CH581) and/or peripherals.

  • Indoor positioning BU01 development board can detect tiny body movements - CNX Software

    GPS is available for outdoor positioning, what about indoors? There is a positioning technology that is more accurate than GPS: UWB. The technology offers positioning accuracy within 10cm which greatly compensates for the shortcomings of the indoor RSSI positioning of past IoT products.

  • ESP32 Pretends To Be GPU; Gives You A Ransomware Scare | Hackaday

    Sometimes a piece of hardware meets a prank idea, and that’s how the fun Hackaday articles are born. [AnotherMaker] shows us some harmless entertainment at the expense of an IT enthusiast in your life – programming an ESP32-powered devboard with a VGA output to show an ever-feared “all your files are encrypted” screen on a monitor connected to it. The ASCII text in its 8-bit glory helps sell this prank, making it look exactly like a BIOS-hijacking piece of malware it claims to be; akin to UIs of the past that skilled hackers would whip up in x86 assembly. The devboard’s integration into a PCI card backplate is a cherry on top, a way to seamlessly integrate this into a PC case, making it look not particularly different from an old graphics card. In such a configuration, we don’t doubt that this would be a head-scratcher to a certain kind of an IT department worker.

  • Some predictions for the year ahead [Ed: Takes note of the role of GNU/Linux in robotics]

    Robotics processor vendors will increasingly offer Robot Operating System (ROS)-based solutions for hardware acceleration across the entirety of robotics offerings.

    This should help tackle the problem of system integration and entice developers to adopt more off-the-shelf processors and hardware.

    Furthermore, the hardware-software optimization will provide a set of benchmarks and standards for the field, which is fairly fragmented at the moment, accelerating the time-to-market.

    As a total of 45,000 cobots and 452,000 mobile robots are expected to be shipped in 2022, a 65 percent and 51 percent Y-o-Y growth, end users are expected to benefit from the tighter integration.

    What will not happen in 2022 includes:

    The democratization of robotics expertise

    While the emergence of ROS and various robotics startups will offer real advances in the short term, robotics as a whole suffers from a significant shortage in expertise.

    In the long run, this will have an adverse effect on development and commercialization. Considerable investment in resource- and time-intensive areas requiring experts from different fields is badly needed, but this will not happen anytime soon.

  • 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.
