The Windows 10 Calculator has been ported to Linux and can be installed from the Canonical Snap Store. The Uno Platform, an open-source toolkit to create cross-platform applications, has been used to port the Windows Calculator (calc.exe) to Linux under the name ‘Uno Calculator’ Using the same code base, developers can port it to other platforms, including Windows, Linux, macOS, and mobile. The toolkit demonstrates the power of the toolkits’ power. In July 2020, Microsoft opened-sourced the Procmon system monitoring utility to Linux.
