My diatribe against “skeptics” (2016)
April 10, 2023. The backlash was immediate after I spoke at the 2016 Northeast Conference on Science & Skepticism , which bills itself as a “celebration of science and critical thinking.” Although the conference had allotted me 10 minutes for questions, the stage manager, Jamy

Who invented vector clocks?
Back in spring 2020, I was wrapping up the distributed systems course I was teaching, and for the last lecture, decided to spend a little time poking at the question of who actually invented vector clocks. Most people who need something to cite for vector clocks cite Friedemann Mattern’s “Virtual Time and Global…

This service relied on sessions, which consisted of interconnected Java objects that were supposed to be cleaned up either when a user logged out or after a predetermined timeout period.

Writing a Simple Garbage Collector in C (2014)
People seem to think that writing a garbage collector is really hard, a deep magic understood by a few great sages and Hans Boehm (et al) . Well it’s not. In fact, it’s rather straight forward. I claim that the hardest part in writing a GC is writing the memory allocator, which is as hard to write as it is to look up…
