egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…

<paculino> Couldn't this just be a link to a GitHub page?
<raptop> I guess the citations section to a degree

<queqiao-> ⟨thunkii⟩ you might as well try to find a fifth Fermat prime by running the CGoL pattern that self-destructs if it finds it
<queqiao-> ⟨thunkii⟩ theoretically possible, never going to happen

<queqiao-> ⟨sleepysaf⟩ curiously, only happens if i decouple […] ⮪ going to try this order:
<queqiao-> 2. time accelerate
<queqiao-> and see if problem persists
<queqiao-> 3. decouple
<queqiao-> 1. pass 140km
<queqiao-> ⟨sleepysaf⟩ +briefly
<queqiao-> ⟨sleepysaf⟩ I'd like to get to the bottom of this because not being able to time accelerate with a probe is unplayable
<queqiao-> ⟨sleepysaf⟩ cannot repro anymore???
