How to Exclude Packages from Transactions using DNF in RHEL Linux

While updating packages in your system, you might not want to allow specific packages from transactions, such as updates, for various reasons, such as bugs or instability in the latest release. Packages such as Kernel, PHP, MySql, Apache, Nginx, Python, etc., are regularly used on the running server. Updating them into unstable releases might lead to a catastrophe event.

• Greece about to secure Router Freedom but leaves fiber out

  Greece is one step closer to securing Router Freedom, but regulators are excluding fiber (FTTH) connections from the legislation. A coalition of organisations, allies of the FSFE, is now requesting that lawmakers reconsider this and thus safeguard the freedom of all users. Since 2021, the regulatory process that defines the network termination point (the NTP) in Greece has been carried out by the Hellenic Telecommunications and Post Commission (EETT). Defining the NTP is necessary to determine whether users have the right to choose their own router and modem or if their Internet Service Providers (ISPs) have the final say over network equipment. In April 2022, we welcomed that the Greek regulator proposed legislation safeguarding Router Freedom for common networks, such as DSL and coaxial. This is a leap forward in safeguarding consumer rights. However, in the same proposal, EETT has explicitly excluded fiber connections (FTTH), a decision that has the potential of negatively impacting end-users’ rights. The proposed regulation sets the NTP for fiber connections in a position that would make the optical terminal equipment part of the ISPs’ networks, making home network access equipment the property of the ISP. The FSFE assisted a coalition of organisations to respond to the EETT’s public consultation, supporting the regulator to implement Router Freedom for all types of internet connection, including FTTH.

• IBM’s AI-powered Mayflower ship crosses the Atlantic [Ed: This was a complete failure. It did not even reach its destination.]

  A groundbreaking AI-powered ship designed by IBM has successfully crossed the Atlantic, albeit not quite as planned. The Mayflower – named after the ship which carried Pilgrims from Plymouth, UK to Massachusetts, US in 1620 – is a 50-foot crewless vessel that relies on AI and edge computing to navigate the often harsh and unpredictable oceans.

• HPE Allies With Red Hat and SUSE on Containers - Container Journal

  At the HPE Discover 2022 conference, Hewlett-Packard Enterprise (HPE) today expanded its reach into container environments via separate alliances with Red Hat and SUSE. The Kubernetes-based Red Hat OpenShift platform along with Red Hat Enterprise Linux (RHEL) operating system and Red Hat Ansible automation platform will be made available via the HPE GreenLake managed service, HPE said.

• Bishop AI: A JavaScript-based Virtual Assistant With Natural Language Processing

  It was created in 2018, making it one of the newest open source software. And it is also released under the MIT license. The program is written in JavaScript, and built to handle Q/A style conversation. [...] Bishop AI is a MIT project; that’s why it is very likely that you will find it already packaged and available to install.

• AI Based Virtual Assistant in Python

  Many automation tools aims to help user in many fields in their life such as opening any application on the system, play and control music, solve mathematical expressions, getting weather details, and more.

• Notes on running containers with bubblewrap

  Hello! About a year ago I got mad about Docker container startup time. This was because I was building an nginx playground where I was starting a new “container” on every HTTP request, and so for it to feel reasonably snappy, nginx needed to start quickly. Also, I was running this project on a pretty small cloud machine (256MB RAM), a small CPU, so I really wanted to avoid unnecessary overhead. I’ve been looking for a way to run containers faster since then, but I couldn’t find one until last week when I discovered bubblewrap!! It’s very fast and I think it’s super cool, but I also ran into a bunch of fun problems that I wanted to write down for my future self.

• Fix: Why Isn’t Linux Detecting My Wi-Fi Adapter?

  Historically, Linux has had a somewhat strained relationship with Wi-Fi cards. In recent years, the situation has changed considerably—and for the better—but it is still possible to boot into your new Linux installation and get that sinking feeling when you realize you’ve got no Wi-Fi. Installation routines are very good at identifying the various components of the target computer and configuring itself to work with that hardware. But problems can still happen. Troubleshooting hardware issues is difficult, especially if the only computer you have on hand is the broken device. Obviously, not everything presented here will be applicable to all cases. But hopefully, something below will either fix your issue or point you in the right direction.

• Open-sourced tool speeds up Linux scripts via parallelization | Network World

  MIT has open-sourced pa.sh (also called pash), a tool that can dramatically speed up Linux scripts by using parallelization, saving time and without risk of introducing errors. The process of parallelization first examines a script for code that can be run separately and independently, so not all scripts can benefit from the tool. But when pa.sh does find portions that can run independently, it runs them in parallel on separate CPUs. It also uses other techniques to get the code to run faster. Below is a demonstration I ran on my home Fedora box, first running a script on its own and then again using pa.sh. Note that this script was provided with the pa.sh tool and lends itself to parallelization. It’s not nearly as demanding as scripts that might process gigabytes of data in a scientific or artificial-intelligence lab, so the results are not dramatic.

• Building in Kubernetes Using Tekton

  Continuous integration/continuous delivery (CI/CD) principles offer multiple benefits to software organizations, including faster time to market, higher-quality code, and simpler and faster fault isolation. Applications built using CI/CD pipeline best practices tend to see a huge increase in users over time, necessitating a migration from a large codebase and low-scalability monolithic architecture to a more manageable and efficient microservice architecture. Kubernetes is one of the most popular platforms for automating the management, deployment, and scaling processes of microservice applications. Because Kubernetes is complex, though, a framework can help developers and operations teams use the platform to follow CI/CD practices in building applications. This is where Tekton comes in.
