Much ado about explosive methane

Posted on 14 December 2020 by ecoquant

Sunday’s Boston Globe had a lead article about the demise of opposition to the Weymouth natural gas compressor station, defeated by Commonwealth and federal support for its operation. Many people I know protested that scourge of Weymouth and the Commonwealth, … Continue reading →

    I have used dlm almost exclusively, except when extreme efficiency was required. Since Jouni Helske's KFAS was rewritten, though, I'm increasingly drawn to it, because the noise sources it supports are more diverse than dlm's. KFAS uses the notation and approaches of Durbin, Koopman, and Harvey.

    ``The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.''
