Parallel R: Quick Ways Model More (The Data Warehouse Insider)

Blogs.Oracle.Com - The Data Warehouse Insider

I am less and less often mistaken for a pirate when I mention the R language.  While I miss the excuse to wear an eyepatch, I'm glad more people are beginning to explore a statistical language I've been touting for years.  When it comes to plotting or running complex statistics in a single line of code, R is a great tool to have.  That said, there are plenty of pitfalls for the casual or new user: syntax, learning to write vectorized code, or even just knowing which "apply" function you really should choose.

  I want to explore a slightly less-often considered aspect of R development: parallelism.  Out of the box, R can seem very limited to someone used to working on compute clusters or even a multicore server.  However, there are a few tricks we can leverage to get the most out of R on everything from a personal workstation to a Hadoop cluster.

Open Government

Open Government | EEDSP | Scoop.it

Open Government was published in 2010 by O'Reilly Media. The United States had just elected a president in 2008, who, on his first day in office, issued an executive order committing his administration to "an unprecedented level of openness in government." The contributors of Open Government had long fought for transparency and openness in government, as well as access to public information. Aaron Swartz was one of these contributors (Chapter 25: When is Transparency Useful?). Aaron was a hacker, an activist, a builder, and a respected member of the technology community. O'Reilly Media is making Open Government free to all to access in honor of Aaron. #PDFtribute

TalkView - Meeting C++

What is good C++11 coding style? Although just ratified in late 2011, we already have early implementations to show us the path to good coding style. Indeed, much of C++11 was designed following rules to allow us to to achieve a superior coding style rather than the litter of bad code that was normal in C++98/03. Gone are the casts, macros, pointers, naked new and deletes, complicated control structures, special cases that don't fit generic programming, and deep nesting. This talk will illustrate the design rules we were aiming for in C++11, many of the pitfalls of migrating from C++98/03 to C++11, and how to achieve good code style using C++11's type-rich interfaces, integrated resource management, uniform generic programming and efficient mapping to hardware. In essence, modern C++11 coding style should be noticeably different than C++98 code, even at a glance. This talk will show you what to look for as code begin to migrate towards C++11.
