Nvidia passes Microsoft in market cap to become most valuable public company - The new dynamic among the top spots is interesting. Nvidia is more similar to Apple than Microsoft since it's trying control the entire stack. It's good that not all the top companies are full stack, but I think it would be interesting to have a top company that was full stack and building exclusively open source software. And for that matter a purely software company that was all open source. I wonder if that's even possible. www.cnbc.com #
