"The purpose of computing is insight, not numbers." (Richard Hamming)

"The reason we model and analyze systems is to gain insight." (C. Nelson Dorny)

At the beginning of April, with the COVID-19 outbreak upending much of life as we previously knew it, I was casually following the case count numbers …

I presented at Utah Code Camp 2015 on machine learning with the Google Prediction API. IPython notebooks are available on GitHub, or they can be viewed directly with the IPython Notebook Viewer here:

• Converting Raw Input Files
• Machine Learning with Google Prediction API
• Taylor Swift Prediction with scikit-learn
• Taylor Swift …

I presented on machine learning and prediction to the Big Data Utah meetings as part of StartSLC 2015. Check out the the slides!

I competed in this year's edition of the Utah Data Competition, a local data science competition. The semiconductor yield prediction problem seemed simple enough on the surface, but it ultimately proved to be quite challenging. I attempted several modeling approaches but eventually converged on two that received most of my …

A little over a hundred years ago, some bright people thought it might be really useful for someone in New York to talk to someone in San Fransisco by telephone. They eventually succeeded in completing the first voice test of the system in 1914, and the first "official" transcontinental long …

After updating to IPython 2.0, I decided to get rmagic working on a Windows 8.1 install. These instructions should probably work with IPyhon 1.X, too, although I have not tried.

R on Windows

Behind the scenes, rmagic assumes that a working version of R is available on …

Here's a quick IPython notebook gist about FFTs in Python. Ironically, most tutorials don't describe how to scale and format the FFT output so that sinusoidal amplitudes are correctly displayed. Sometimes that's important. If you don't have IPython installed, the notebook can be viewed using the awesome IPython Notebook Viewer …

Two good articles on exporting C++ classes from a DLL from Eli Bendersky and Alex Blekhman. I've researched this before and found varying degrees of intelligibility. These seem to be fairly complete yet concise.

Analog engineering legend Bob Pease killed in car crash

As a university student I took a job in an electronics lab while studying mechanical engineering. I guess the job required that you could solder and do a little metalworking, so I qualified on the latter and learned the former. In …

The words or the language, as they are written or spoken, do not seem to play any role in my mechanism of thought. The psychical entities which seem to serve as elements in thought are certain signs and more or less clear images which can be 'voluntarily' reproduced and combined …
