  • AVA Developer Platform offers 32 64-bit Arm cores, 32GB RAM, 10GbE for $5,450 - CNX Software

    The AVA Developer Platform was announced together with ADLink COM-HPC Ampera Altra server module for embedded applications with up to 80 64-bit Arm cores, up to 768GB DDR4, 4x 10GbE, and 64x PCIe Gen4 lanes.

    The AVA Developer Platform is not fitted with the top-end COM-HPC module, but still, with a 32-core COM-HPC Ampere Altra module fitted with 32 GB DDR4 memory, plus a 128 GB NVMe M.2 SSD, and an Intel Quad X710 10GbE LAN card, it still makes an impressive workstation for native Arm development. We did not know the price the last time, but now we do as the workstation is available for pre-order for $5,450.

  • USB board emulates CR2032 or CR2016 coin cell battery - CNX Software

    You can now develop CR2032 or CR2016 powered devices without having to use an actual coin cell thanks to Peter Misenko’s (Bobricius) “coin cell battery emulator CR2016/CR2032”.

    The USB board contains a rounded part that is compatible with CR2016 or CR2032 coin cell batteries and allows you to power your target board via USB. The board also includes holes for alligator clips to measure the current, and by extension the power consumption.

  • RPi CM4 based local storage server launches on Kickstarter

    KubeSail has launched a compact, $250 “PiBox” NAS and local clouding hosting server powered by a RPi CM4 with dual native SATA SSD bays for up to 16TB plus GbE, HDMI, 2x USB, 40-pin, and KubeSail software for private clouds.

    Self-hosting cloud startup KubeSail has gone to Kickstarter to successfully fund its compact network-attached storage (NAS) and storage server called the PiBox. Built around the Raspberry Pi Compute Module 4 (RPi CM4), the system offers dual, PCIe-driven native SATA bays for 2.5-inch SSDs.

  • Raspberry Pi CM4 based PiBox 2 Mini serves as NAS, private Cloud storage (Crowdfunding) - CNX Software

    The PiBox 2 Mini is a networked storage solution based on a Raspberry Pi CM4 module and equipped with two slots for 2.5-inch SATA drivers be it HDD’s or SSD’s. It also exposes USB ports and an HDMI port, so I could also be used as a computer.

    Designed by KubeSail “self hosting company”, the PiBox does not only serve as a standard NAS, but aims to provide a home-based private cloud hosting solution that can replace services such as Google Photos or Dropbox with easily installable templates that are hosted in the box.

  • Surf Sensor Adds Depth To Finding The Ultimate Wave

    o say that the ocean is a dynamic environment would be a gross understatement, especially when coastlines are involved. Waves crash, tides go in and out, and countless variables make even the usual conditions a guessing game. When [foobarbecue] goes surfing, he tries to take into account all of these things. The best waves at his local beach are directly over an ever-moving sand bar, and their dynamics are affected by depth, another constant variable. [foobarbecue]’s brilliant solution to understanding current conditions? Build a depth finder directly into his surf board!

    At the heart of the “surfsonar” is the Ping Sonar Echosounder, a sonar transducer designed for AUV’s and ROV’s. [foobarbecue] embedded the transducer directly into the board. Data is fed to a Raspberry Pi 4b, which displays depth and confidence (a percentage of how sure it is of the measurement) on a 2.13 inch e-Paper Display Hat.

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.
