  • As a casual self-hoster for twenty years, I ran into a consistent pattern: I would install things to try them out and they’d work great at first; but after installing/uninstalling other services, updating libraries, etc, the conflicts would accumulate until I’d eventually give up and re-install the whole system from scratch. And by then I’d have lost track of how I installed things the first time, and have to reconfigure everything by trial and error.

    Docker has eliminated that cycle—and once you learn the basics of Docker, most software is easier to install as a container than it is on a bare system. And Docker makes it more consistent to keep track of which ports, local directories, and other local resources each service is using, and of what steps are needed to install or reinstall.



  • Clarification: data can be sent at c, but electronic data can’t. Electrons have mass and can’t move at the speed of light; the electromagnetic waves they carry can move at the speed of light in the medium through which the electrons are conducted, which is still slower than c. Photons, on the other hand, can transmit optical data at c (which still doesn’t do anything unexpected with respect to time).












  • Skimming through the cited paper, it looks like their conclusion is based less on a detailed model of the climate as much as a general property of dynamical systems and how plausible it is that current climate processes could result in a chaotic state.

    What I’d like to see is if the more detailed models used in most climate forecasts are able to capture the sort of dynamics they describe. (Not predicting the outcome, obviously, but maybe predicting the circumstances in which a transition to a chaotic regime could occur.)
