Setting up RStudio Server quickly on Amazon EC2
I have recently been working on projects using Amazon EC2 (elastic compute cloud), and RStudio Server. I thought I would share some of my working notes. Amazon EC2 supplies near instant access to on-demand disposable computing in a variety of sizes (billed in hours). RStudio Server supplies an interactive user […]

Apple machines historically have sat at a sweet spot of convenience, power, and utility: Convenience: Apple machines are available at retail stores, come with purchasable support, and can run a lot of common commercial software.

Neural net image salad again (with code)
Alexander Mordvintsev, Christopher Olah, and Mike Tyka, recently posted a great research blog article where they tried to visualize what a image classification neural net “wants to see.” They achieve this by optimizing the input to correspond to a fixed pattern of neural net internal node activation. This generated truly […]

“The Mythical Man Month” is still a good read
Re-read Fred Brooks “The Mythical Man Month” over vacation. Book remains insightful about computer science and project management.
Must Have Software
Having worked with Unix (BSD, HPUX, IRIX, Linux and OSX), Windows (NT4, 2000, XP, Vista and 7) for quite a while I have seen a lot of different software tools. I would like to quickly exhibit my “must have” list. These are the packages that I find to be the […]
