Small world! Around 1995, he had pinged me as we were among the (then very small) se(c)t of @Debian developers, and I (as a semi-permanent visitor) had been using a @queensu handle (his alma mater).
Doug was instrumental in me getting into R. So big thanks to @BatesDmbates !

It was twenty years ago ... this week that I first showed up in debian/changelog for the r-base package.

Old and "hard" problem: if you want to guarantee rng streams across systems / languages you need to implement your own.
See eg Paul Gilbert in his R/Finance 2012 keynote referencing work he did in the 1990s at the Bank of Canada comparing R and S-Plus.

Ok - thank you. I don't need anymore. So random.seed() doesn't lead to same sequence of random numbers in Python 2.7 as in Python 3. Anyone have a work around?

Second music recommendation in two days: a really nice video essay on why John Coltrane's 1959 album Giant Steps is such a monumentally important piece.
And I also learned the title track is 290 bpm :)

With the untimely coming demise of @GooglePlus, our small group of @lballabio @CaspersPeter and myself are "forced" to continue our habit of sharing music somewhere else.
No let's start here with another 26 wicked minutes of live music by @TheNational: youtube.com/watch?v=jscmj8Iz…

Thanks to @RogerBivand for having me to talk to his @nhhnor "Business Analytics" students for an hour over @appear.in -- that was fun, and I hope I didn't scare anybody away from participating in @OpenSourceOrg
