Big Thank You to @joshua_ulrich for this work, and for tirelessly slaying several dragons while doing it. Or, as he calls it, a regular day working with Windows.
Instructions at github.com/eddelbuettel/rqua… still hold, now for 0.4.4 too.
FOSS Trading: New Windows binaries for RQuantLib 0.4.4!

Still having tons of fun with @quasardb , C++ and R.
Now with a new 2.3 version of the C API thanks to @edouarda14 we have full queries. Which map wonderfully into data.table.
Next: write a loader for nanosecond timestamp data, then query.

Inbox a moment ago: "i wrote a question on Stalkoverflow" [sic]
Best way to ensure I ignore a question is to ask it via Twitter, Twitter DM, LinkedIn (groan) or by spamming my inbox.
So a "Pro Tip": Use. A. GitHub. Issue. Ticket.
Pretty-please.

Two maintenance releases on CRAN this week:
- digest 0.6.13 allowing serialize version for R 3.5.0 / ALTREP
- RVowpalWabbit not using a directory change for tests
digests creates hash digests, RVowpalWabbit is a fast learner.

Here are some thanks to @Nate_Cohn and the @UpshotNYT team for a fantastic demonstration of what _live_ predictive modeling can do. Double thanks for turning the effing jitter off. As @statpumpkin called; finest stats porn.

Brilliant. And yet so sad.
Same as it ever was.
And you may say yourself, "My God! What have I done?"
