I have some ideas for data coding (more on that in a later post) but it required me to do some heavy weight math. It has been a long time since I did math so I needed some refreshers. One amazing resource is the online MIT classes at MIT Open Course Ware. They have video lectures, class notes and exercises for freshman to graduate.

I’m making my way through freshman calculus. Have to begin somewhere and I’ve forgotten a lot. It’s like a foreign language — if you don’t use it, you loose it.

Spring is starting to happen here in the Willamette Valley. Some parts of the country are under snow and floods but here, in a milder place, the cherry trees are blooming.
