> But did you know ClickUp has a desktop application that includes at least one feature your teams could seriously benefit from? The app is available for Linux, macOS and Windows, and it adds native desktop notifications to the experience. That feature alone is worth installing the desktop application.


> Think about it: You use ClickUp every day to stay ahead of your project’s demanding schedule. Although you can get notifications in the browser, for that to work, you have to have the ClickUp tab running and your browser configured to allow desktop notifications. If your browser doesn’t allow you to configure per-site notifications, you could easily be inundated with them.

↺ How To Install AnyDesk on Fedora 37 - idroot

This can be useful for providing remote support, collaborating with team members, or accessing files and applications on a different computer. To use AnyDesk on Linux, you will need to install the AnyDesk software on both the remote and the local computer, and then use the AnyDesk address of the remote computer to establish a connection.


> 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 the AnyDesk remote desktop on a Fedora 37.

How to Install Mono on Debian [Ed: But Mono is Microsoft trouble]


↺ How to Install Mono on Debian

↺ Mono is Microsoft trouble


> Mono is a free and open-source .NET Framework-compatible, cross-platform development framework. It implements Microsoft’s .NET legacy for a number of platforms using a single codebase, including Windows, macOS, and Linux. Mono can be thought of as a toolkit working much like Microsoft’s .NET Framework does, however it is released as Free and open-source software under the MIT license rather than being proprietary software.


> The main goal of Mono is to allow for the creation of .net applications on different platforms without restrictions from other toolsets. This includes the same DLL file format so that no code has to be rewritten for new platforms and the same infrastructure for executing .NET applications so that the same APIs can be used.
