  • Opening black boxes with statement tracing | Red Hat Developer

    Imagine you're a programmer with a problem: Your code is linked to a library that you're unfamiliar with. The code should work, but it doesn't. It almost works, but something is wrong inside the library. Another program works correctly with the same part of the same library. So, now what? It's probably a silly problem, but how will you locate it?

    In a scenario like this one, you could be in for some serious source code gazing, documentation digestion, and mailing list archaeology. If that fails, it's time to reach out to human experts and hope for the best. Or, you could try to save time with a clever tool. I was recently hit with several code traps like this one. Fortunately, I'm familiar with SystemTap.

  • Managing stateful applications with Kubernetes Operators in Golang | Red Hat Developer

    You can use Kubernetes Operators to set up automatic resource management for services in your applications. In a previous article, I described this pattern and how to create an operator in the Go language. In this article, we will continue to explore the pattern, this time by creating a Kubernetes Operator in Go to keep a WordPress site up to date. I recommend reading or reviewing the earlier article before starting this one.

  • Using Amazon EFS with Podman running on RHEL EC2

    Podman is a daemonless container engine for developing, managing, and running OCI containers on your Red Hat Enterprise Linux (RHEL) system. In this post, I will create a photo gallery running in a Podman container on a RHEL Amazon Elastic Compute Cloud (EC2) instance, where the photos displayed by the website are stored on the EC2 instances connected to AWS Elastic File System (EFS) across multiple Availability Zones (AZs).

    Amazon Elastic File System (Amazon EFS) provides a serverless, set-and-forget elastic file system that can be used with AWS cloud services and on-premise resources. It’s built to scale on demand to petabytes without disrupting applications. Amazon EFS helps eliminate the need to provision and manage capacity to accommodate growth.

  • Hybrid work by the numbers: 14 stats to see | The Enterprisers Project

    By at least one measure, people are returning – or planning to return – to the traditional office in 2021. A Deloitte survey of 275 executives conducted in April found that more than two-thirds of respondents (67 percent) were still fully remote at the time. But 64 percent expected their organization to return to the office at some point in 2021, and another 25 percent said they’d already reopened.

    In spite of some high-flying predictions – and high-profile company announcements – about long-term shifts to working from home, just two percent of the executives in the Deloitte survey said their organizations would remain permanently remote.

  • IT hiring: 5 ways to evolve your strategy

    COVID-19 has fundamentally changed how we work – and how we think about work – today and well into the future. As a result, it has prompted a reboot of how organizations recruit and onboard new employees.

    The struggles of the past year have also prompted many workers to rethink their career priorities, quitting their jobs in extraordinary numbers – with a record 4 million people doing so in April alone, according to the U.S. Labor Department. This has ushered in an era some pundits are calling “The Great Resignation,” creating a higher-than-usual demand for workers. And this has many employers – especially those in high-demand technology settings – scrambling to find adequate talent to fill the many job openings.

    CIOs in particular are struggling to accelerate digital transformation and ensure the latest technologies are available, a requirement for attracting tech-savvy workers – and of course, the customers they are striving to please.

  • 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.
