• setupSSO.sh : SAML SSO in Univention UCS Server

  The official HowTo on setting up SAML SSO basically covers the process of setting it up, but my impression was, that this process can be made better, less error-prone and more reproducible by automatting the setup. So I wrote in my spare time a small shell script to follow the instructions from the official HowTo and after many tests and enhancements, I released the script on Codeberg: setupSSO.sh.

• 3 Ways to install Steam on Linux Mint or LMDE - Linux Shout

  Here we learn the commands to install and use Steam client’s latest version on Linux Mint based on Ubuntu or LDME Debian based to play games.

Only games that are originally published by the developers with Linux support can be. Yes, indeed as compared to Windows the numbers of the games are not much for Ubuntu or other Linux distributions but whatever is there yet a good source to satisfy the binge of gaming on open source platforms. The games are protected with DRM.

6 Top Free and Open Source Groovy Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Groovy is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform aimed at improving developer productivity thanks to a concise, familiar and easy to learn syntax.

• Kernel now 5.15.60 with RTLXXXU driver

  I have had email communications with Muthukrishnan, Realtek wifi not working, but it does work on a different Linux distribution. He has investigated firmware, but narrowed the problem down to a missing kernel driver. This is part of one of his emails: The issue appears to be that CONFIG_RTL8XXXU is not set in the kernel config setting. Since the firmware for my laptop is RTL8723BU, it appears to be not loading it at the time of booting.

• How SQLite Helps You Do ACID

• Level up your HTML document with CSS | Opensource.com

  When you write documentation, whether that's for an open source project or a technical writing project, you should have two goals: The document should be written well, and the document should be easy to read. The first is addressed by clear writing skills and technical editing. The second can be addressed with a few simple changes to an HTML document. HyperText Markup Language, or HTML, is the backbone of the internet. Since the dawn of the "World Wide Web" in 1994, every web browser uses HTML to display documents and websites. And for almost as long, HTML has supported the stylesheet, a special addition to an HTML document that defines how the text should appear on the screen. You can write project documentation in plain HTML, and that gets the job done. However, plain HTML styling may feel a little spartan. Instead, try adding a few simple styles to an HTML document to add a little pizzazz to documentation, and make your documents clearer and easier to read.
