  • The Raspberry Pi Pico As An SDR Receiver | Hackaday

    With the profusion of cheap RTL-SDR devices and the ever-reducing prices of more capable SDRs there might seem to be little place left for the low-bandwidth devices we’d have been happy with a decade or more ago, but there’s still plenty to be learned from something so simple. It’s something [Luigi Cruz] shows us with a simple SDR using the analogue-to-digital capabilities of the Raspberry Pi Pico, and since it works with GNU Radio we think it’s rather a neat project. CNX Software have the full story, and and quickly reveal that with its 500k samples per second bandwidth it’s not a machine that will set the SDR world on fire even when pushing Nyquist’s Law to the limit.

  • Raspberry Pi CM4 based mini-PC offers M.2, dual GbE

    OnLogic is prepping a fanless, industrial Raspberry Pi CM4-based mini-PC with dual GbE, 4x USB, micro-HDMI, serial, and M.2 for SATA.

    In honor of yesterday’s Pi Day celebration, OnLogic has teased an unnamed mini-PC due later this year that runs on a Raspberry Pi Compute Module 4. The “real industrial Raspberry Pi” appears to be OnLogic’s first Arm-based computer.

  • Onlogic industrial Raspberry Pi CM4 based mini PC to offer dual GbE, USB 3.1, M.2 SATA socket

    Yesterday, we covered two Raspberry Pi CM4 carrier boards with dual Ethernet ports, including one from Seeed Studio with dual Gigabit Ethernet and USB 3.1 ports, and another from MCUZone with Gigabit + Fast Ethernet ports, USB 2.0 ports, plus a 4G LTE modem.

  • UP Squared Pro SBC gets more I/Os, 3x M.2 sockets, TPM 2.0 security chip

    UP Squared Apollo Lake SBC was launched in 2016 via a crowdfunding campaign with a price starting at just 89 Euros for the model with 2GB RAM 16GB storage, and a dual-core Intel Celeron N3350 processor.

    AAEON has now announced an update simply called UP Squared Pro with many of the same features, but greater expandability and I/O features, for example, to add 5G modules and AI accelerators through one of the three M.2 sockets, as well as improved security via a TPM 2.0 chip.

  • Sparkfun Thing Plus - Quicklogic EOS S3 Arm eFPGA board launched in Crowd Supply

    Just like QuickFeather, Sparkfun EOS S3 board can run FreeRTOS or Zephyr RTOS, supports TensorFlow Lite and SensiML machine learning software, as well as open-source FPGA tools such as SymbiFlow and Renode. You’ll find links to software resources in our previous post about QuickLogic EOS S3 SoC.

    The Quick connector will give access to over 150 Qwiic-compatible expansion boards, which are connected through a 4-pin JST polarized Qwiic cable, and daisy-chainable to add two or more Qwicc expansion modules to your project.

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.
