First, to let you know, I've created a seperate blog, USACO coding blog, for specific coding stuff or math-ish stuff. All others, like EE, will remain on this blog.
Also, I had a fun time at Maker Faire Bay Area 2015, and met some awesome people, such as Arduino co-founder, Massimo Banzi, and Raspberry Pi founder, Ebon Upton.
