Statistics::RserveClient, a new Perl interface to R

Sun, 03/31/2013 - 13:25

I'm pleased to announce the first public beta release of Statistics::RserveClient, a Perl module providing an interface for interacting with the powerful open-source R platform for statistical computation.

Using RserveClient, a Perl applications can make a connection to a (possibly remote) Rserve server, send R commands as strings, and receive the results of the evaluation as Perl data structures.

Since Rserve communicates via a binary protocol, computations can return plots and other binary data.

Using RserveClient is straightforward:

What's up with the WeBWorK Problem Library?

Mon, 06/18/2012 - 09:54

WeBWorK's extensive library of problems (numbering almost 29,000 entries, at current count) is one of the great attractions of the system. I'm planning a post discussing some statistics about the growth of the library and the distribution of authorship, types of problems, and so on, but that will have to wait for another day. What I wanted to highlight today is current work on the library, and plans for future directions.

What's with the Name?

One of the most noticeable changes for casual users is the name change. At the recent Code Camp in Rochester, there was an extensive discussion of this topic. We wanted to choose a new name that reflected the fact that WeBWorK is now international. This fact is also manifesting in the recent work in internationalizing and creating translations for the WeBWorK user interface. But the existing moniker ("National Problem Library") was starting to feel a bit constrained and unnatural. In the end, we voted on WeBWorK Open Problem Library, or just OPL for short.

This choice was intended to emphasize WeBWorK, the software (or project, or brand, if you

WeBWorK Rochester CodeCamp 2012

Fri, 06/15/2012 - 11:57

I spent most of last week participating in an intensive code sprint/code camp for WeBWorK. I've been using the software for over three years, and hacking on it for about two, but this was my first real meeting with many of the community members.

I'll go into more detail in a later post, but for now I'll just say I was incredibly impressed by the technical expertise, passion and energy, thoughfulness, and openness of the community. It was humbling and inspiring to be welcomed to such an atmosphere of warmth, trust, and positivity, and super cool to be working with a group whose experience ranged from 2nd year undergrad to emeritus professor.
