  • 3 key considerations for your trusted compute base

    This isn't the first article I've written about trusted computing bases (TCBs), so if the concept is new to you, I suggest you have a look at What's a trusted compute base? to get an idea of what I'll be talking about here. In that article, I noted the importance of the size of the TCB: "What you want is a small, easily measurable and easily auditable TCB on which you can build the rest of your system—from which you can build a 'chain of trust' to the other parts of your system about which you care."

    In this article, I want to discuss the importance of a TCB's size, how you might measure it, and how difficult it can be to reduce its size. Let's look at those issues in order.

  • What you need to know about Quarkus in 2021

    Part of publishing services on the cloud is providing users and developers easy access to those services through easy and reliable means. One of the most popular methods of interfacing with applications online is through an application programming interface (API), a fancy term that means you allow users to interact with your app through code.

    The API concept is significant because it helps others build upon your app. Suppose you design a website that returns a random number when a user clicks a button. Normally, that would require a user to navigate to your site and click a button. The site might be useful, but only to a point. If you included an API, a user could just send a signal to your server requesting a random number, or they could program something of their own that "calls" your server for a number with no clicking or manual interaction required. A developer could use your random number as a value for a game or as part of a passphrase generator or whatever else developers need random numbers for (there's always something). A good API unlocks your application for others to use your code's results, transforming your work on the web into, essentially, a software library.

  • Building a real-time leaderboard with Red Hat Data Grid and Quarkus on a hybrid Kubernetes deployment

    Red Hat Data Grid, built on the Infinispan community project, has been a key component of the Red Hat Summit keynote demonstration for several years, and the first part of our virtual summit in April 2021 was no exception. This year, we built an online Battleship game that was deployed across three continents and hosted on Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. If you missed the live action with Burr Sutter, you can catch the video replay on YouTube.

    In this article, we’re going to take a closer look at Data Grid's role in the demonstration, explain the architecture, and break down some of the technical details behind what Burr calls “that Data Grid magic.”

  • IT leadership: 5 steps to foster inclusive decision-making

    Everyone with a good idea should be given the respect to have that idea thoughtfully and authentically considered. Everyone, regardless of demographic, should be able to freely contribute and lend their expertise to the conversations when decisions are made. It isn’t just the morally right thing to do; it makes good business sense.

    To accomplish this within Research & Development at Tricentis, we use a framework called “R&D Thinks.” Participation is not limited to the R&D department. We also invite solution architects, support engineers, marketing content strategists, product marketing managers, and others to participate – and they do!

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.
