> Release Candidate versions are available in testing repository for Fedora and Enterprise Linux (RHEL / CentOS / Alma / Rocky and other clones) to allow more people to test them. They are available as Software Collections, for a parallel installation, perfect solution for such tests, and also as base packages.
> Here’s your weekly Fedora report. Read what happened this week and what’s coming up. Your contributions are welcome (see the end of the post)! F37 Beta was released on Tuesday.
> I have weekly office hours on Wednesdays in the morning and afternoon (US/Eastern time) in #fedora-meeting-1. Drop by if you have any questions or comments about the schedule, Changes, elections, or anything else. See the upcoming meetings for more information.
> Silverblue is an operating system for your desktop built on Fedora Linux. It’s excellent for daily use, development, and container-based workflows. It offers numerous advantages such as being able to roll back in case of any problems. Let’s see the steps to upgrade to the newly released Fedora 37 Beta, and how to revert if anything unforeseen happens.
> Before attempting an upgrade to the Fedora 37 Beta, apply any pending upgrades.
> If there's anything business leaders can count on over the last few years, it’s that you can’t count on anything. With a volatile job market, changes in employee priorities, and the lasting effects of COVID-19, there’s no way leaders can guarantee employee satisfaction, motivation, and retention.
> Company executives learned quickly that their efforts to retain and motivate employees must be continually addressed and shifted to succeed in today’s climate. With hybrid or fully remote work options being the new norm, knowing the feelings, needs, and motivators of employees has become even more critical.
> The Java runtime environment in your containers could stop receiving updates in the coming months. It's time to take action. This article explains the decisions that led to this issue and proposes a solution.
> Filtering and searching text with regular expressions is an important skill for every developer. Regular expressions can be tricky to master. To work with them effectively, you need a detailed understanding of their symbols and syntax.
> Fortunately, learning to work with regular expressions can be incremental. You don't need to learn everything all at once to do useful work. Rather, you can start with the basics and then move into more complex topics while developing your understanding and using what you know as you go along.
> This article is the second in a series. The first article introduced some basic elements of regular expressions: The basic metacharacters (.*^$\s\d) as well as the escape metacharacter \.
> This article introduces some more advanced syntax: quantifiers, pattern collections, groups, and word boundaries. If you haven't read the first article, you might want to review it now before continuing with this content.
> These articles demonstrate regular expressions by piping string output from an echo command to the grep utility. The grep utility uses a regular expression to filter content. The benefit of demonstrating regular expressions using grep is that you don't need to set up any special programming environment. You can execute an example of a regular expression immediately by copying and pasting the code directly into your terminal window running under Linux.
