  • Pulling changes from GitHub to Git - The Linux Juggernaut [Ed: Careful not to conflate Microsoft proprietary software with Git, which is Free software. Git is not GitHub.]

    In our previous article, we demonstrated how we would push our git repositories from our local system out to GitHub. In this article, we will demonstrate how we would actually make changes in a file within a repository on GitHub and then pull the changes/updates to our local machine.

  • Fixing git/github merge conflicts - The Linux Juggernaut

    In our previous article on the git version control system, we explained how we could modify our files in repositories in our GitHub account and then pull the changes from GitHub to the git repositories on our local system and keep the files in synchronization. Now, what if we modified the same piece of information in a file on GitHub as well as within our local git repository? In this article, we will demonstrate how we would proceed if we modified the same information in a file on GitHub as well as locally within our git repository.

    Although there are tools that can display Linux system info graphically, however, here we are going to use the inbuilt commands.

    The question of how a system is equipped and how it performs in harsh everyday life is not only of theoretical interest. Lot’s of time to solve a problem we need to know hardware and its utilization to remove some bottleneck. Thus, if you are new to Linux systems or running any cloud server where you want to know about the system load, the network interface, and type of processor and chipset, or what hardware is actually in the system? Then here some top commands to follow…

  • How to Run Google Chrome OS from a USB Drive – Linux Hint

    Google Chrome OS is based on the open-source Chromium OS. It is a browser-based operating system. You will only have the Google Chrome web browser installed on it. You can install Chrome web apps or extensions from the Chrome Web Store and add more functionality to the operating system.
    Sadly, the Google Chrome OS is not publicly available for download, and only the source code of Chromium OS is publicly available. So, you can’t run the Google Chrome OS or Chromium OS directly on your computer.

This week in KDE: Adaptive panel opacity and auto-restored unsaved documents in Kate!

A big Plasma feature was added this week: adaptive Plasma panel opacity! Now the panel and panel applets are more transparent than they were before, allowing more of a tint from the beautiful wallpaper on your desktop! But what’s this? You’re about to complain that you maximize all your windows so the increased transparency will look ugly? In fact, we now make your panel and panel applets 100% opaque when there are any maximized windows, ensuring no ugly effect! But what if you don’t want that either? Well, if you don’t want adaptive opacity we now let you make your panel and panel applets always transparent, or always opaque! Hopefully that should make everyone happy. Let’s give a round of applause to Niccolò Venerandi and Jan Blackquill for this work, which will show up in Plasma 5.22. Read more

Self-supported Red Hat Enterprise Linux Server virty users see stealth inflation

Red Hat Enterprise Linux Server has maintained the same starting price over the past few years. Now, changes to the way the software is licensed have doubled the cost for some self-support customers using virtual machines. The change dates back to 2019, when Red Hat said its Red Hat Enterprise Linux Server, Self-support (RH0197181) was in the process of being retired and has been superseded by Red Hat Enterprise Linux Server Entry Level, Self-support (RH00005). According to a Red Hat spokesperson, RH00005 debuted in 2013 and RH0197181 stopped being sold in 2015. Both of these RHEL SKUs sell, or were sold, for $349 in the US. But only the discontinued product allows the use of virtualization at the lowest price tier. Now customers who opted for the discontinued entry-level offering have found they need to pay more than twice as much ($799 for the standard tier) to run a guest VM on a physical system. What's more, Red Hat in its subscription guide declares that its self-supported option "is not intended for production environments," making it clear that self-supported commercial usage with VM support requires greater investment that before.
