  • Framework Laptop Now Enjoys Open-Source EC Firmware

    While just one part of the overall equation for a system with open-source firmware, the Framework Laptop has joined the ranks of the Linux-focused laptops these days being backed by open-source firmware for its embedded controller (EC).

    Framework announced last month that as part of "open sourcing our firmware" they have now published the EC firmware.

  • An Entire Computer In ICMP Packets | Hackaday

    The earliest stored program computer in the modern sense was not one of the names such as ENIAC or Colossus that you might expect, but the Manchester Baby, an experimental prototype computer built at the University of Manchester in 1948. Its 550 tubes gave it the multi-rack room-filling size common to 1940s machines, but its architecture makes it a comparatively simple processor by the standards of today. So simple in fact, that [Hrvoje Čavrak] has recreated it using ICMP packets as its storage, and a custom packet filter as its processor emulation. It’s a project that’s simultaneously both elegant and gloriously pointless, but as he says, “It’s still better than doing drugs or JavaScript”.

  • This sneaky ransomware is now targeting Linux servers, too | ZDNet [Ed: It's not a Linux issue; ZDNet is a very Linux-hostile site, funded partly by Microsoft]

    One of the most prolific families of ransomware now has additional Linux and VMware ESXi variants that have been spotted actively targeting organisations in recent months.

    Analysis by cybersecurity researchers at Trend Micro identified LockBit Linux-ESXi Locker version 1.0 being advertised on an underground forum. Previously, LockBit ransomware – which was by far the most active ransomware family at one point last year – was focused on Windows.

  • Vulnerabilities that aren’t. Cross Site Tracing / XST

    This is the first of my posts that explain why some common security vulnerabilities are most likely not real threats. They should be treated as security enhancements rather than vulnerabilities. Bearing in mind the number of scanning tools that rate such vulnerabilities as “high” it’s no wonder people make the mistake of reporting them. It’s also a reminder to mistrust the output from something until you’ve verified it.

    I’m going to start with the not-a-vulnerability mother of them all, the HTTP TRACE (and TRACK) method. Something that could lead to an attack called Cross Site-Tracing (XST). In 20 years I have never seen a real-world exploit for it.

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.
