New BH release 1.51.1-3

A new release of the BH package is now on CRAN and its mirrors. BH provides (a subset of) the Boost library for C++, particularly the (large) parts delivered as pure template headers not requiring linking.

When this package is installed, an R package developer can deploy it at build-time via a simple LinkingTo: BH declaration (which, despite the title affects only compilation, not linking; don't ask...). This frees developers from having to include the (sizeable) Boost headers in their packages, and provides (parts of) Boost as part of the R build system.

A short example of using this BH package with Rcpp is provided in this Rcpp Gallery post; a number of other Boost-related posts are also available.

This release expands the scope of the package by a quite bit as shown in the NEWS entry:

Changes in version 1.51.0-3 (2013-10-19)

The other change is that I am now acting as maintainer taking over from Jay who has headed the initial creation and first releases after he, Mike and I had talked about this for way too long without actually doing anything about it. Thanks for getting everything rolling, Jay!

Comments and suggestions are welcome via the mailing list or issue tracker available via the package page at R-Forge.

Yes another Herbie Hancock concert

Hadn't mentioned yet that I saw Herbie Hancock last Friday at the CSO / Symphony Center. That's about the fourth time I have him according to this blog (September 2007,March 2005, April 2004) and I think I saw him two more times when I lived in France, and maybe once while I was in Canada.

This time, the format was a horn-free quintet with Lionel Loueke on guitar, James Genus on bass, Vinnie Colaiuta on drums and Zakir Hussain on tabla. Hancock himself played mostly keyboards / synthesizer, even when he used the full piano as input. Overall the concert was little uneven--Hancock himself alluded to the fact that the five hadn't really practised together. At times they were rolling: the opening was a very rhythmic version of his very old standard Watermelon Man; the encore was a very rocking version of his best-selling pop-fusion hit Rockit. In between, it was sometimes wanting. Still, all five are tremendous artists and I also had a fabulous seat as shown in this Google+ post with a picture of Hancock's setup, including multiple screens. But they did not really connect with audience as a whole, and by the time the encore rolled around, the house was pretty empty.
