Devices: Spectrogram and Boards With (Optional) Linux

  • Spectrogram Drawing For Fun And Coding | Hackaday

    The code is a bit slow so writes its values to a file which is output by a HackRF, but it could just as easily be used by any other capable output device such as GNU Radio and a soundcard if you too want an Aphex Twin moment.

  • Fanless Coffee Lake computer targets testing and analysis

    No OS support was listed for the Neu-X302, but the Neu-X300 runs Linux or Win 10. The new Coffee Lake Refresh options range up to the octa-core, 1.8GHz/2.2GHz Core i7-9100TE with 35W TDP. Once again, there is a choice of Intel Q370 or Intel H310 I/O chipsets, creating two SKUs. However, there are fewer feature differences.

  • Arm-based IoT gateway reaches out with WiFi, Bluetooth, LTE, and NB-IoT

    Aaeon’s compact “SRG-3352C” IoT gateway is equipped with a TI AM3352, 3x USB, 2x RS-485, 2x GbE, WiFi/BT, mini-PCIe with micro-SIM, and an NB-IoT connector.

    It’s always a bit troubling when vendors omit the name of an embedded system’s processor. However, Aaeon’s fanless SRG-3352C Compact Edge IoT Gateway System, which is said to be based on an 800MHz, Cortex-A8 SoC, gives away the mystery in its name: the IoT gateway no doubt features the aging TI Sitara AM3352. No OS support was listed but given the AM3352 — the lowest end model in the AM335x line, with no 3D GPU or PRU-ICSS cores — Linux is almost certainly supported.

  • Embedded Artists launches 1GHz NXP i.MX RT1176 Crossover MCU module and devkit

    Anders Rosvall, CTO at Embedded Artists AB, explains the i.MX RT1176 uCOM board “enables customers to move up to application-level performance without having to move to the Linux world”, and provides an update from the company’s iMX RT1064 uCOM with double the SDRAM, MIPI-DSI interface, and a 2D graphics engine. In case you wonder why a company would not want to move their application to a Linux platform, reasons include code reuse, faster real-time responsiveness, and lower power consumption.

  • Cortex-A7 module debuts with optional Pico-ITX carrier

    DH unveiled a “DHCOM STM32MP1” module that runs Linux on ST’s Cortex-A7/M4 SoC with up to 1GB RAM, 16GB eMMC, and WiFi/BT. “DH PicoITX2” and “DH PDK” carriers are also available.

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.
