  • How open organizations can harness energy disruptions

    Many people talk a lot about the values of Open Organization Principles, but in many ways, they require people to change how they do things, which can be difficult. That is true for businesses and industries as well. Disruption in many sectors is coming. How do we use Open Principles to address them? This article looks at what's happening in industries related to energy and transportation when it comes to drastic costing changes that will lead to industrial disruption. Business disruption is happening through new technology or methods, which will slash costs. This is forcing industrial change. Consider the oil, coal, natural gas, nuclear, petroleum, biofuels, and charcoal (the primary energy in many developing countries) industries. All these industries are grouped in the fossil fuel-burning energy-generating industry. Imagine them all becoming obsolete and totally replaced by the solar and wind industries in the next decade or so because of costs. That is industrial disruption.

  • OpenTelemetry: A Quarkus Superheroes demo of observability

    Are you building microservices? Do you struggle with observability and with capturing telemetry data between distributed services? This article shows how to quickly and easily introduce OpenTelemetry into a distributed system built on Java with Quarkus. This combination allows you to visualize the interactions between all the microservices within an overall system. The article introduces the official Quarkus sample application, Quarkus Superheroes, deploys it on the free Developer Sandbox for Red Hat OpenShift, and demonstrates how to collect and visualize telemetry data in order to observe microservices' behavior.

  • Python requirements.txt File

    “We need to employ a lot of modules while creating Python apps for various functionalities. The number of modules a given application uses can be considerable. Generally, it is advised to create a virtual environment tailored to the project when developing such massive programs, as well as smaller ones, because doing so enables us to install anything we want and of any version without overburdening the available package space. The script and dependencies must be installed on the user’s computers for them to utilize the developer. Because the dependencies are set up in a virtual environment, it would be useless to share the entire virtual environment because the folder size would be enormous, and there would be a risk of integrity problems. When this occurs, programmers include a requirements.txt file in the project that contains a list of all the dependencies that have been installed in the virtual environment as well as information on the version that is being utilized. To utilize the program, the borrower or end-user merely needs to set up a virtual environment and install any necessary components. This post will explain how to create the requirements.txt file and install dependencies using it.”
