  • Tiny, dual-GbE Raspberry Pi CM4 carrier sells for $30

    DFRobot’s $30, 66 x 55mm “Compute Module 4 IoT Router Carrier Board Mini” extends the Raspberry Pi CM4 with 2x GbE, 2x Type-C, microSD, and 26-pin GPIO.

    Earlier this month, we saw the first dual-Ethernet carrier boards for the Raspberry Pi Compute Module 4 in Seeed’s Dual Gigabit Ethernet Carrier Board (2x GbE) and Mcuzone Raspberry Pi CM4-4G IO (GbE and 10/100). Now DFRobot has opened $30 pre-orders for a Raspberry Pi Compute Module 4 IoT Router Carrier Board Mini with dual GbE ports. At 66 x 55mm, the board is even smaller than the 75 x 64mm, $45 Seeed carrier.

  • Open-spec Piunora and MirkoPC carriers for RPi CM4 feature M.2 for NVMe

    Diodes Delight has launched a $39 “Piunora” carrier for the Raspberry Pi CM4 with Arduino, ADC, and Qwiic expansion, and Mirko Electronics is prepping a “MirkoPC” carrier with dual HDMI and a DAC.

    Lately, it seems, most of the interesting embedded Linux news has been about carrier boards for the Raspberry Pi Compute Module 4. This morning we covered DFRobot’s tiny, $30 Compute Module 4 IoT Router Carrier Board Mini with dual GbE ports. Here we look at the Arduino-like Piunora board, which just went live on Crowd Supply, plus an upcoming MirkoPC CM4 carrier board. Jeff Geerling recently dropped a YouTube video that used a Mirko Electronics MirkoPC prototype to demonstrate beta code released by the Raspberry Pi Foundation to enable booting from NVMe (see farther below).

  • Arm v9: First New Architecture in a Decade Doubles Down on AI and Security

    Arm has launched a major architecture revision, Arm v9, which provides additional features for security, confidential computing and AI as well as boosting overall performance. Arm said it expects v9 to deliver more than 30% performance uplift in the next two mobile and infrastructure generations. AI features, thus far most typically available with GPUs, will be available across the company’s GPUs, CPUs, and NPUs.

  • Arm’s v9 Architecture Explains Why Nvidia Needs To Buy It

    Many of us have been wracking our brains why Nvidia would spend a fortune – a whopping $40 billion – to acquire Arm Holdings, a chip architecture licensing company that generates on the order of $2 billion in sales – since the deal was rumored back in July 2020. As we sat and listened to the Arm Vision Day rollout of the Arm V9 architecture, which will define processors ranging from tiny embedded controllers in IoT device all the way up to massive CPUs in the datacenter, we may have figured it out.

  • Arm launches v9 architecture – Arm

    Today, Arm introduced the Arm®v9 architecture in response to the global demand for ubiquitous specialized processing with increasingly capable security and artificial intelligence (AI). Armv9 is the first new Arm architecture in a decade, building on the success of Armv8 which today drives the best performance-per-watt everywhere computing happens.

  • Armv9: The Future of Specialized Compute

    One year ago, as Arm’s global workforce began adjusting to remote working, we knew that technology would be key to weathering the storm.

    Across the complex data-driven networks supporting all areas of the business world, we saw how technology enabled us to keep communicating and collaborating. The sudden switch to a digital-first life for Arm’s 7,000 people was almost seamless, and we were all able to keep pushing our design and engineering efforts without much interruption.

    Looking back, I’m hugely grateful for the resilience of our people, and our partners. Now, as we think about a return to working together face-to-face, we’re once again considering how technology can speed our path back to shared physical workspaces.

  • Arm Announces ARMv9 Architecture With SVE2

    ARMv9 is introducing the Arm Confidential Compute Architecture (CCA) for confidential computing with dynamically created "Realms", Scalable Vector Extensions 2 (SVE2) for greater machine learning performance and digital signal processing capabilities, and other improvements over ARMv8.

Piunora has the guts of a Raspberry Pi 4 with Arduino...

  • Piunora has the guts of a Raspberry Pi 4 with Arduino form factor, M.2 PCIe socket (Crowdfunding)

    The Raspberry Pi 4 is a pretty cool board, but if you wished it was just a bit smaller, and you could use the PCIe interface exposed by the Broadcom BCM2711 processor more easily, Timon has designed Piunora carrier board for the Raspberry Pi Compute Module 4.

    The solution provides a board with the guts of Raspberry Pi 4 SBC but using the Arduino form factor including access to the six ADC pins, and an M.2 socket with the PCIe signal from the Broadcom SoC.

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.
