No, it was Sunday to Sunday. Sorry I could not swing by Milan itself. In and out via MXP was all.

Congratulations. Also wrapped up for @Debian as usual and stuck into my PPA, and RQuantLib for #RStats continues to build and test unchanged. Brought to you from a rainy day in Lombardy, for once.
#QuantLib 1.32 was released today. Thanks to all contributors! github.com/lballabio/QuantLi…

You can now parse URL more efficiently in R, using the same C++ library that Node.js relies upon. You get full support for WHATWG URL! @eddelbuettel
Someone wrote a R wrapper for Ada, and it's 40 times faster than the alternative? github.com/schochastics/adaR

Please see the available documentation which covers this. Briefly: 1) Debian is not Ubuntu. #r2u is for #rstats on Ubuntu. 2) MSys is still Windows so no go. But many Windows users deploy #r2u via WSL2 which works very well as it is Ubuntu based.

#r2u going strong: now over ten million packages served, including two 1.5 millions plus days last month. More about #rstats on Ubuntu with all of CRAN plus a chunk of BioConductor as binaries via `install.packages()` at eddelbuettel.github.io/r2u #r2u: Fast. Easy. Reliable.

Indeed. In 2008 I wanted to "easily" short housing, and the CME obliged later (these contracts are still thin-ish in trading). More recently this nonsense was crying for shorting. So give me the Arrow-Debreu completion promised in grad school classes! Preferably as an ETF.

Yes, my own case as a kid in Lower Saxony was simple too (bicycle) but I was mentioning the more recent experience as a parent here in Cook County. Worked well for us, but during runs in the area one sees lots of cars idling in school queues.

We survived by being in walking distance to primary and middle schools, and an easy bike ride to the high school. Location. Location. Location. Oh and city designs matter.

Code nicely abstracts away the implementation 'detail'; meat and bones of the example above is a four-line loop---thanks to the new helpers. #rstats #rcpp
Coming soon to #rstats helper package `RcppInt64`: `nanotime` helpers for to/from C++ conversion. Example showing how the 'delta' is consistently one ns across the 18 orders of magnitude range. #rstats #rcpp
