  • FreeIPA Server on Alma Linux 8/CentOS 8 - Unixcop

    We have 3 users, Jhon, Doe, Mike. Suppose you are at the IT department for a Software Company. You have to manage the identity of those 3 users. Easy right? You can easily manage their Identity Access. But how about 3 users become 300 or 3000? How can you manage them?

    Well things get pretty hard I guess, How about if we can have a system that has a central identity info, maybe that would be easier to solve our stated problem.No worries, FreeIPA is here to help you by solving the problem.

  • Add Client to the FreeIPA Server on CentOS 8 - Unixcop

    Hi Everyone ! In the previous article, we have seen how to set up freeIPA Server on centOS 8.

    In this write up, we will show how to add a client host to the freeIPA Domain. We will be configuring a CentOS 8 machine to authenticate against an existing FreeIPA server.

  • How to Install KDE Plasma Desktop Environment on Ubuntu 20.04 - LinuxCapable

    The name KDE comes from “K Desktop Environment”. For those not familiar with KDE Desktop, it is a free, open-source desktop environment. It provides Linux users on various distributions an alternative graphical interface to customize their desktop environment and applications for everyday use enhancement.

    Besides the graphical enhancements and changes, it is also a lightweight, fast, smooth environment with superior performance compared to native shipped desktops with some Linux Distributions. In Ubuntu’s case, this is Gnome.

    At the end of the tutorial, you will have learned how to install KDE Desktop Environment on your Ubuntu 20.04 system.

  • How To Install NVIDIA Drivers on Fedora – TecAdmin

    Fedora, the operating system of RHEL(Red Hat Enterprise Linux) does not have pre-installed exclusive Nvidia drivers in it for the users. Although it does have default Nouveau drivers which work in most conditions, you may face some problems while using them. If you encounter issues while using the Nouveau drivers you will have to install the official proprietary Nvidia drivers.

    The official Nvidia drivers can help you get the most out of your GPU by enhancing its performance. In this article, we will learn to install the official Nvidia drivers on Fedora

    However, before we start with the installation process, we need to do system configuration. The first configuration we need to do is stop the GUI from running and the second step is to disable the default nouveau drivers. From the GRUB boot menu, it is really easy and doable.

  • Securing your Kubernetes cluster with Kubewarden

    Kubernetes is fast becoming the operating system of the cloud. Every major cloud provider has a supported Kubernetes platform, Kubernetes can be run on-premises, and Kubernetes even has a package manager with Helm.

LibreOffice extension to remove blank cells – Help to improve it!

Rafael Lima from the Brazilian LibreOffice community is working on an extension to remove blank cells in LibreOffice Calc. It has four modes (single column, single row, blank rows and blank columns). Here’s a quick animation of it in action... So far, the main functionality is there, but Rafael would like to improve it. We asked him for some more info… Read more

5 Best Free and Open Source TypeScript Static Site Generators

LinuxLinks, like most modern websites, is dynamic in that content is stored in a database and converted into presentation-ready HTML when readers access the site. While we employ built-in server caching which creates static versions of the site, we don’t generate a full, static HTML website based on raw data and a set of templates. However, sometimes a full, static HTML website is desirable. Because HTML pages are all prebuilt, they load extremely quickly in web browsers. There are lots of other advantages of running a full, static HTML website. Read more

You Can Now Install KDE Plasma 5.23 on Kubuntu 21.10, Here’s How

Released last week, Kubuntu 21.10 ships with KDE Plasma 5.22.5 as default desktop environment, but users who want to use the recently released KDE Plasma 5.23 “25th Anniversary Edition” desktop environment can now upgrade their installations if they have the Kubuntu Backports PPA repository installed. The Kubuntu team announced today that the KDE Plasma 5.23.1 packages are now available in the Kubuntu Backports PPA repository, along with the KDE Frameworks 5.87 and KDE Gear 21.08.2 software suites, to make your Plasma desktop and KDE apps experience better.

  • Labyrinthian Circuit Sculpture Evokes Moods With Sound And Light | Hackaday

    We can’t help but wonder if [Eirik Brandal] was evoking such Wilde thoughts when he wrote to tell us about ddrysfeöd, an electronic sound and light sculpture which he called “uselessly applied electronics.” Given the mood created by the video below the break, we have to agree that it is indeed quite artful. But if it serves a purpose to inspire and cause wonderment, is it really useless? Let the philosophers philosophize. On to the hack!

  • This Arduino radio looks like something from 100 years ago | Arduino Blog

    As time has progressed, personal radios have shrunk from the size of a large filing cabinet down to a tiny circuit that can be integrated into other ICs. Instructables user exposedwire wanted to bring back the feeling of a vintage 1920s radio set, so they built one out of wood that carries the same antique feeling with some more modern features. For the electronics, exposedwire went with an Arduino Uno for the main control board, along with a TEA5767 FM receiver IC that communicates with the Uno over I2C. The currently tuned frequency is displayed on a seven-segment LED module, which is driven by the ubiquitous TM1637 chip. The station can be changed by rotating the accompanying rotary encoder. Finally, the resulting audio signal is sent from the TEA1637 to an NS8002 amplifier and outputted from a small speaker.

  • Quit Hunching Over Your Screen With A Little Robotic Help | Hackaday

    This simple Arduino-based build uses the ubiquitous MPU-6050 which provides 3-axis acceleration and 3-axis gyro data all processed on-chip, so it can measure where you’re going, which way you are orientated and how fast you are rotating. This is communicated via the I2C bus, so hooking into an Arduino or Raspberry Pi is a simple affair. There are plenty of Open Source libraries to work with this very common device, which helps reduce the learning curve for those unfamiliar with programming a fairly complex device.
