Armadillo 5.000 released -- major new features.
http://arma.sourceforge.net

- added spsolve() for solving sparse systems of linear equations
- added svds() for singular value decomposition of sparse matrices
- added nonzeros() for extracting non-zero values from matrices
- added handling of diagonal views by sparse matrices
- expanded repmat() to handle sparse matrices
- expanded join_rows() and join_cols() to handle sparse matrices
- sort_index() and stable_sort_index() have been placed in the delayed operations framework for increased efficiency
- use of 64 bit integers is automatically enabled when using a C++11 compiler
- workaround for a bug in recent releases of Apple Xcode
- workaround for a bug in LAPACK 3.5

The Armadillo code base is now made up of 125,000+ raw lines of code, which is about 86,000+ lines without comments, blank lines, etc.

Self-recommending.  I caught most of it last night when it was streaming live.
One of today's great singers celebrates the centennial of a jazz icon. Wilson brings her fresh arrangements of classic tunes to the Kennedy Center in Washington, D.C.

This is good fun: Answer 24 questions revealing regional variation in use of German, and get a guestimate of your (linguistic) "home".  

And it is weird -- while I have been gone for 25 years (!!), the analysis based on the 24 answers put me ... squarely in the wrong place. Oh well.

RcppArmadillo 0.5.000.0 is now on CRAN and in +Debian 

This took a moment as I missed a regression / need for change with two packages that has now done.   Nice set of changes coming from Armadillo as Conrad posted a few days ago.

For the Android users: a bunch of free apps for Android today -- including +Wolfram|Alpha which I didn't yet have installed.
Amazon's running another one of their signature Android app giveaways, highlighted this time around by the likes of Plants vs. Zombies, Wolfram|Alpha, Runtastic PRO, and Osmos HD. If you own an Android device, take a minute to check out the full list and download anything you might want before the deal ends. [Amazon Appstore]

Happy Birthday, Herbie Hancock!  You'll always be Chicago's favorite son to me.

With a hat tip to +NPR over on Twitter, and thanks for the show recording.
The keyboard giant brought a stellar group of musicians to the JVC Jazz Festival Newport to help perform classics from his catalog, as well as recent reconfigurations of pop music.

Caught most of the full show last week in the live recording / live streaming and it is awesome.   Highly recommend.

Thanks to +KEXP  for this, and to +NPR for the tweet...

So wrong :)
Warning: this comic occasionally contains strong language (which may be unsuitable for children), unusual humor (which may be unsuitable for adults), and advanced mathematics (which may be unsuitable for liberal-arts majors). BTC 1FhCLQK2ZXtCUQDtG98p6fVH7S6mxAsEey ...

You gotta admit that sometimes the easy solution is the better one... although pulling power during a drive write or something could be catastrophic.
