  • Making Java programs cloud-ready, Part 4: Optimize the runtime environment | Red Hat Developer

    This is the final article in a series where we are updating a monolithic Java EE application to function as a microservice and run in a distributed cloud environment such as Red Hat OpenShift. In the first article, we set up the legacy Java application and defined our goals. Then, we upgraded the Java environment to Jakarta EE. In the last article, we used MicroProfile to prepare the application for use in a distributed environment.

  • IBM emeritus IWB: What Musical Mindsets Can Teach Us About Business Innovation

    Over the past few decades, creativity and innovation have received increasing attention in the business world. For example, the overriding finding of a Global CEO Study conducted by IBM in 2010 was that creativity is the most crucial factor for future success. The IBM study interviewed more than 1,500 CEOs from 33 different industries and 60 countries, who overwhelmingly said that creativity, - even more than management discipline or strategic vision, - was the key leadership quality required to navigate an increasingly volatile and complex world.

  • Modernizing retail banking with blockchain, Red Hat and HCL

    The global financial system has long been at the forefront of technological change. Initially, banking institutions had minimal systems and fewer products, instead, the focus was on regular in-person customer interactions. However, as the global reach of finance grew, so did the need for proxies and platforms.

    At present, there is a need to simplify this multi-system approach within banks and streamline the flow of data among various banking platforms. The concept of distributed ledger on blockchain can help a bank share information across the board internally or with different banks under the same network. Blockchain ledgers are hard to tamper with. Transactions written to a blockchain cannot be amended, making it easier to establish accountability and reduce dispute among network participants.

    Cross border transactions is an area that has been heavily looked upon as a blockchain use case and one of the most lucrative opportunities for innovation. Cross border payments account for $130 trillion USD annually as per The 2020 McKinsey Global Payments Report (PDF). Banks usually have to incur high charges for cross border transactions.

    These charges can be as high as 10% of the transaction because of the hops a transaction goes into till it finally settles with the end customer. Using blockchain tokens, transactions can be done in real time with ledgers reflecting the transacted tokens between banks. This can be achieved using smart contract functionality where a smart contract can hold the business logic agreed between banks and once a transaction is executed, the shared ledger will keep the record immutable. These transaction records can help in reconciliation and faster settlements.

  • Managing secrets for Kubernetes pods | Enable Sysadmin

    The term container is not new in our collective IT vocabulary. Currently, many utilities are available in the industry for managing containers. Kubernetes is one of them and it provides container orchestration tools. In Kubernetes, pods are deployed. You can create containers in these pods. Kubernetes also offers several ways to keep your data secure. When you deploy a pod in a Kubernetes cluster, hiding sensitive data about the pod is an essential part of the deployment.

  • Oliver Gutierrez: Non destructive system tests for Toolbox

    Toolbox system tests were developed for using them in the Tooolbox CI. Because of that, that tests were not designed with local execution in mind. I've spent some time working on this tests to make them executable locally.

    The system tests basicly use podman and skopeo to execute the setup and test tasks. They are run with the bats test suite, and they do a heavy handling of images and containers to run the different tests needed for Toolbox.

  • 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.
