  • UP Squared 6000 - AAEON introduces Elkhart Lake SBC and Edge computer - CNX Software

    AAEON has unveiled a new single board computer and edge system from the “UP bridge the gap” family with UP Squared 6000 equipped with Intel Atom x6000, Celeron, or Pentium Elkhart Lake processor, up to 8GB DDR4, 64GB eMMC flash, two Gigabit Ethernet ports, DisplayPort 1.2, HDMI 2.0b, eDP video interfaces, SATA and M.2 storage, and more.

    The UP Squared 6000 is available in four different SKUs with notably an industrial SKU powered by the Intel Atom x6425RE optimized for automation, robotics, and industrial applications with support for Intel Time Coordinated Computing (TCC), Time-Sensitive Networking (TSN) via its 2.5GbE port.

  • Rockchip RK3588 datasheet available, SBC's coming soon - CNX Software

    We had most Rockchip RK3588 specifications so far for the long-awaited Cortex-A76/Cortex-A55 processor, but at today’s Rockchip Developer Conference 2021, more information surfaces with impressive CPU and GPU benchmarks, and the Rockchip RK3588 datasheet has just dropped from the sky directly into my laptop, as such document usually does. At least two single board computers are expected to soon follow from Radxa and Pine64.

  • Keynote Video: Elecia White Finds Treasure In The Memory Map | Hackaday

    Elecia starts out with the map file from a “hello world” program, but it’s a hello world running on an RTOS, so already there’s enough meat to dig into. She starts out with the top-level overview: flash for the code and RAM for the program to use. In flash, the code lives in .text and .const, and RAM has sections that should be familiar to you like .heap and .stack, but also .data and .bss. The memory map file also follows this structure: first an overview, then the section markers, and then the details of what’s inside each section.

    If you get a crash, for instance, and you know where the numerical value of program counter when it went all pear-shaped, the .text section lists the function name where that happened. The section with global variable definitions, listed alphabetically? You can probably just scroll on by that — there’s a lot of redundancy in the map file, sometimes sorted by memory address, sometimes sorted alphabetically. You don’t want to read a map file, you just want to dip in, get what you need, and get out. Got a variable that you think is getting overwritten? Find it in the section listed by address, and look at its neighbors — one of them might be overrunning.

  • Small-scale autonomous boat made out of recycled water bottles and a Tupperware container | Arduino Blog

    As part of their city’s beach restoration project, Instructables users Kousheek Chalraborty and Satya Schiavvina, who go by the team name Technovation, needed to construct a small and cheap boat that could assist in mapping the depth of the sea floor at various locations. The design they were able to come up with achieved this goal and even went beyond it by incorporating an autonomous navigation system into their watercraft.

    The hull of the boat was made from a leftover Tupperware container and discarded water bottles, therefore reducing the cost significantly and integrating recycled materials. After the pontoons were attached to the bottom, a pair of brushless DC motors were screwed into place at the top, along with an 11.1v LiPo battery and dual 30-amp ESC modules.

  • This maker designed an interactive LED-lit dress inspired by Katniss Everdeen's | Arduino Blog

    Inspired by Katniss Everdeen’s burning dress from the Hunger Games series, Cindy Li set out to create her own version that uses fabric-attached LEDs to both simulate fire when movement is detected and illuminate in other ways when a certain button is pressed.

    This light-up dress was based around two development boards: a Circuit Playground Bluefruit from Adafruit that handles the lights and an Arduino Nano RP2040 Connect, which connects to a sensor, some buttons, and a speaker for extra functionality. Li started building this project by sewing the Circuit Playground onto he fabric and then running a strip of individually addressable LEDs in an arch shape, with conductive thread tying it all together. Next, the Nano RP2040 Connect was wired to the speaker, buttons, and APDS-9960 sensor and placed within a custom-cut acrylic enclosure. Finally, another string of LEDs was wrapped around the bottom of the dress to act as the “fire” component.

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.
