MySQL transactions per second vs. fsyncs per second (2020)
Just wondering how many transactions or writes per second MySQL can handle? While it depends on many factors, fundamentally, about as many transactions as MySQL can commit to disk per second. A modern disk can do ~1000 fsyncs per second , but MySQL will group multiple writes with each fsync. An okay rule-of-thumb…

Tabular Programming: A New Paradigm for Expressive Computing
I've been exploring the m8 Dirtywave tracker for a few months now, and it's been a fascinating experience. If you're not familiar with it, the m8 is a portable music sequencer built on the Teensy platform that combines a minimal 8-button interface with a powerful tabular workflow. What makes it special isn't just its…

Quirks of Common Lisp Types
Humans have a tendency toward binary thinking (pardon the pun). If it's not A, it's B. Perhaps because Lisps have REPLs, they are often thought of from the outside as being dynamic, interpreted languages. Our years of Python have taught us that such languages don't really have strong typing - it's all a wild guess…
