HTML5 Canvas Issue: Half-Pixel Offset
One of the issues I encountered when working with the HTML5 canvas element was the issue of pixel alignment. I made sure that the only size definition was given in the HTML declaration for the image itself as in:

To know and not to do is not yet to know. This idea has been attributed to many sources. Let’s assume it is essentially Buddhist. The same idea is expressed below in terms of neuroscience. These items are saying that … Continue reading
Lack of sleep() in Javascript
I get it. I really do. Javascript is intended to work in a (mostly) single threaded way and allowing it to sleep could gum things up tremendously. Reading that and similar links has been beneficial and I’ll be making time … Continue reading
Simulation: Continuing Yesterday’s Analysis
Yesterday I analyzed some of the considerations involved in modeling a section of a petrochemical refining process, namely that of hydrodesulfurization. That is adding hydrogen to hydrocarbons containing sulfur in the presence of a catalyst at an elevated temperature so … Continue reading

Simulations: What Gets Modeled And What Doesn’t
When I’m not flogging away at code these days I’m thinking about continuous simulations and the details that get modeled within them. Specifically I’ve been reading about and thinking about operations in petrochemical refineries, and even more specifically certain classes … Continue reading
