  • Responding to Growing Demand, Edgewater Launches Wi-Fi Spectrum Slicing Development Kit

    Wi-Fi Spectrum Slicing offers breakthrough performance, slicing available spectrum, and exposing a new level of Wi-Fi spectrum granularity for developers to exploit. Edgewater’s groundbreaking MCSR™ silicon solutions and advanced Linux drivers allow the global Linux community to use the widely adopted Linux and OpenWrt software platforms to harness Edgewater’s technology and invent new and creative applications for the platform.

  • Rugged Kaby Lake vehicle PC does it all on the road or rail

    Vecow’s Linux-friendly “IVH-9024MX ICY” in-vehicle PC runs on a 7th or 6th Gen Core or Xeon CPUs and offers triple displays, 6x SATA bays, 4x PoE+ ports, 2x mini-PCIe, and EN50155: 2017 and EN45545-2 railway compliance.

    Vecow unveiled the rugged IVH-9024MX ICY back in June as an all-purpose in-vehicle and rolling-stock computer and this week announced certifications for EN50155 and EN45545-2 (fire protection) railway safety standards. This is the first 7th Gen Kaby Lake based fanless embedded system to receive these certifications, claims Vecow.

    • Get started with... Arduino?

    Yes, you read that title right, and no, you haven’t accidentally stumbled upon the Arduino Foundation’s website. Today, we’re pleased to announce a new addition to the Raspberry Pi Press family: Get Started with Arduino, a complete how-to guide to help you get hands on with the other pocket-sized board.

  • Exploring Zyxel GS1900 firmware with Ghidra

    Earlier this year the NSA released Ghidra, a reverse engineering suite with support for a large number of CPU/MCU instruction sets. While I have some experience with Hopper and radare2 I wanted to play with Ghidra to poke around the firmware for my Zyxel GS1900-8 switch which runs on a 32-bit MIPS CPU. All in all this has turned out to be an interesting exploration of both Ghidra and the GS1900-8-2.40(AAHH.2)C0.bix firmware image.

    Initially I wanted to write about poking around the firmware image and showing how one can use Ghidra to explore unknown binaries, but whilst looking around some libraries that are used by this switch I realised there is actually an interesting vulnerability to write about.

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.
