Windows, OpenSSH & keys
Since the end of 2017, Microsoft offers native OpenSSH-functionality in Windows 10. And while PuTTY has accompanied me for a number of years, I'm not exactly sad to finally get 'the real deal', so I can painlessly pretend I'm being productive while I'm on Windows (No, that's not a game you see minimized in the taskbar. Move along, peasant!).
