Porting Firecracker to a Raspberry Pi 4 (2019)
Since we got our hands on the new Raspberry Pi 4, we started exploring how various virtualization technologies behave on the board.

Longbets: A bioerror will lead to one million casualties by Dec 2020
Biotechnology is plainly advancing rapidly, and by 2020 there will be thousands-even millions-of people with the capability to cause a catastrophic biological disaster. My concern is not only organized terrorist groups, but individual weirdos with the mindset of the people who now design computer viruses. Even if all…

The social side of science seen in the research on programming language quality
I love science. Not the “space is beautiful” faux-science, but the process of doing science. Hours spent calibrating equipment, cross-checking cites of cites of cites, tedious arguments about p-values and prediction intervals, all the stuff that makes science Go. And, when it does happen, the drama. I also want us to…
