I had some time to play with a WowWee Rovio robot recently. It is having a battery charge issue where it runs out of charge quickly. A guy posted a fix for his Rovio battery issue online where he found a diode was installed improperly. However, in my case it appears the diodes match the silkscreen direction.

Machine Learning Class
I'm struggling through a machine learning class in LA. It is difficult to find the time for it and it is a very specialized topic.
On the other hand, seeing how math can be applied to solve problems with a computer is interesting. It seems that using a dedicated tool is a better start than coding up something in C#. For example, I've seen Roborealm applied to machine vision. Presumably using its gui is easier than using opencv. In class there was a demo of R and Jags. I've played a little bit with R in the past to plot some data and run a linear regression on it, but I feel like I'm just barely scratching the surface of this topic.

Software Requirements
A professor in the UK has the "No Silver Bullet" paper online.
This point from the paper is something I'm trying to remember and maybe follow up on later by reading about how Agile software development attempts to address this.
Requirements refinement and rapid prototyping. The hardest single part of building a software system is deciding precisely what to build. No other part of the conceptual work is as difficult as establishing the detailed technical requirements, including all the interfaces to people, to machines, and to other software systems. No other part of the work so cripples the resulting system if done wrong. No other part is more difficult to rectify later.
