  • Hardening Virtio for emerging security usecases

    Traditionally, when looking at a virtio device and its corresponding virtio driver, we assume the device is trusted by the driver. We do, however, need to protect the virtio device from a possible malicious virtio driver.

    The logic behind this approach is that the virtio driver is a "smart" software element which could contain malicious software logic while the virtio device is a "dumb" element capable of doing only what it’s asked to do. Another reason for this logic is that we traditionally focus on protecting the host from the workload running on it containing the virtio driver (be it a virtual machine (VM) or a container) or protecting workloads from each other.

    Emerging hardware frameworks and security frameworks are turning things around by shifting the focus to protecting the virtio driver from the virtio device. One reason for this change is emerging smart NIC technologies that contain virtio devices that are transformed from "dumb" elements to sophisticated elements that are also capable of running malicious software.

  • Using habits to practice open organization principles | Opensource.com

    Habits are a long-term interest of mine. Several years ago, I gave a presentation on habits, both good and bad, and how to expand on good habits and change bad ones. Just recently, I read the habits-focused book Smart Thinking by Art Markman. You might ask what this has to do with open organization principles. There is a connection, and I'll explain it in this two-part article on managing habits.

    In this first article, I talk about habits, how they work, and—most important—how you can start to change them. In the second article, I review Markman's thoughts as presented in his book.

  • Q&A: 3 digital transformation questions and answers about boosting team productivity

    Even after two years of rapid technology adoption, it’s rare to find a company that has a clear and accurate understanding of how each individual employee uses technology at work – and what they need from those tools.

    In this interview, Stanley Huang, Moxo's Chief Technology Officer, shares what organizations need to focus on in the years to come. He offers tips for CIOs and CTOs to help unburden employees and increase productivity through technology in the workplace.

  • How to convert a web application to Software-as-a-Service [Ed: Application you do not control. Someone else controls it remotely.]

    Software-as-a-Service (SaaS) offers a compelling opportunity for developers who create software originally intended to run at web scale. Having a single code base that runs a variety of enterprise-level business applications reduces the labor that goes into creating and maintaining the software that supports it all. The promise of "one code base to rule them all" makes developing SaaS platforms a value proposition that's hard to ignore—as long as the development team has the expertise to make their ideas real. You need to know a thing or two about creating SaaS platforms. They are a bit of a different beast than single-purpose web applications.

    There are two ways to create a SaaS platform. One is the "greenfield" approach: Build a SaaS platform from scratch. The other way is to transform an existing web application into a SaaS platform.

    This article takes a look at the second way. I describe how to transform an existing web application into a SaaS platform with the help of a concrete, yet fictitious, business named Clyde's Clarinets. The goal of the article is to describe how to transform Clyde's Clarinets into a SaaS platform named Instrument Resellers.

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.
