Far Too Young to Die
He seemed to be healthy; he was active in Twitter, hardly at Microsoft's GitHub, so the death was sudden and unexpected (health or young age is not a guarantee of life)
Daniel Bristot de Oliveira's blog was last active a year ago and it's still online, but he himself has just died and there are short tributes outside Microsoft's LinkedIn.
Daniel Casini, an Assistant Professor, said (in Microsoft's LinkedIn) that he "suddenly passed away at the age of 37, probably due to a heart attack."
I don't want to speculate about work-related stress (certainly fatal in Debian's case; he worked for Red Hat, according to this obituary, for over a decade) or the exceptionally high death rates (excess deaths) that include many unforeseen cardiac events which millions attribute to COVID-19 or the barely-tested vaccines (that's hardly a fringe or niche belief). See In Memory of Daniel Bristot de Oliveira or the screenshot below. It's sad that they break the news of the death of a Linux developer in a proprietary Microsoft platform that spies and censors a lot. █
