## How do I upgrade Lambda Stack from Ubuntu 16.04 to 18.04?

I ran the code above and it seemed to have worked. When it was done I typed ‘sudo reboot’ as indicated. The system rebooted and now I am looking at the Ubuntu screen for the past two days. The dots change color which makes me think it is re-configuring itself. Is that correct? Will it come up in the end?

## Best Deep Learning book for beginners?

I also have two books (actually three but one is at home) on deep learning. One is called Deep Learning by Goodfellow, Bengio and Courville (MIT Press, 2016) and Deep Learning - A Practitioners Approach by Patterson and Gibson (O’Reilly, 2017). The first book has a website at [www.deeplearningbook.…](http://www.deeplearningbook.org/)

I reviewed a book for the Technometrics journal that was just published. The book was called The Essentials of Data Science - Knowledge Discovery Using R by Graham J. Williams (CRC Press, 2017). It is actually a companion to another book called Data Mining with Rattle and R by Graham Williams (Sprint).
