  • How To Install Play Framework on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Play Framework on Ubuntu 20.04 LTS. For those of you who didn’t know, Play Framework is a framework that allows us to make web applications with Java and Scala in a fast and easy way. These applications are based on scalability and the possibility that they can be adapted to many different needs.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Play Framework on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to Fix Sudo Command Not Found in Debian 10

    Sudo also called “superuser do” is a command in Linux that allows you to run high-privilege admin commands as a root user. It asked to enter your personal password and confirms your requests by checking a sudoers file.

    After a fresh Debian 10 installation, you could not execute the privileges tasks by running the sudo command. You will get the error ‘sudo command not found in Debian 10′. The reason for this error is the sudo command isn’t included in Debian 10 by default.

    In this post, we will show you how to fix sudo command not found in Debian 10 VPS.

  • How to Transfer Files Between Linux, Android, and iOS Using Snapdrop

    Cross-platform file sharing has never been easy. Of course, you have services like AirDrop, Nearby Share, and Quick Share, but they only work within their ecosystems.

  • What to do when your Chromebook is no longer supported

    Recently, my Chromebook Pixel 2015 found itself no longer supported. I really loved that Chromebook. The two of us wrote several novels together and the keyboard/screen was unmatched. To this day I've yet to experience a better keyboard/trackpad combo. But, as they say, all things must end. So, when I received the notification that my Chromebook Pixel would no longer be receiving updates, I felt a tinge of sadness. Sure, I had a Pixelbook as a backup device, but it just wasn't the same. It had a nice keyboard, but it was nowhere near that of the Pixel. And the screen? There was zero comparison.

    I had a choice: Continue using the Pixel, even though it would no longer be receiving upgrades, or do something about it.
