Lattice vs. ggplot2
Both lattice and ggplot2 seem really interesting and worthy of learning. But I only have time to learn one of them, and the choice is not an easy one.Here is an awesome reference; this blog is generally very interesting; and here is something...
Random generators for parallel processing
Given the growing interest in parallel processing through GPUs or multiple processors, there is a clear need for a proper use of (uniform) random number generators in this environment. We were discussing the issue yesterday with Jean-Michel Marin and briefly looked at a few solutions: given p parallel streams/threads/processors, starting each generator with a random 
Google Tech Talk on Integrating R and C++: video and slides

Where People Share Links About NYC
Last week I participated in bit.ly’s fourth hackabit hack-a-thon, which is a wonderful opportunity for NYC area hackers to get together, eat pizza, drink energy drinks, and stay up late hacking with some of the best data geeks around. I was lucky enough to saddle up next to Hilary Mason, bit.ly’s lead scientist, recently named
Zero Inflated Models and Generalized Linear Mixed Models with R.
