Installed elementaryOS on one of antique PCs at work (language school) because it was struggling with Windows 8...
Convinced the boss to put Linux on his own computer.

Today, the colleague for whom I did this told me that she said to one of her students that some programmer (Meeee 😀) told her to stop using some stupid unsecured local mail providers and to use ProtonMail.

Was very proud... Why life not like this everyday.
