The CT Scanner is indeed an astounding marvel of engineering. This is what it looks like with the covers off.

9 quintillion calculations later ("one of the largest computations ever"), a crypto breakthrough from Google:

Dalai Lama: "Everyday, think as you wake up, 'today I am fortunate to have woken up, I am alive, I have a precious human life, I am not going to waste it. I am going to use all my energies to develop myself, to expand my heart out to others, to achieve enlightenment for the benefit of all beings, I am going to have kind thoughts towards others, I am not going to get angry or think badly about others, I am going to benefit others as much as I can.'"

Hopefully, this video will help convince more people of how serious the situation is, so that together we can help to reverse the trend!

No one can do everything, but everyone can do something.

Google's super awesome technical marvel Spanner DB is available as Cloud Spanner
Nice to see the release of Cloud Spanner today! I helped design and implement Spanner along with many other people in order to provide a strongly consistent, geographically distributed database system that could be used in our products. Google's advertising systems was one of our primary early customers for Spanner. Now the same system can be used externally.

Engineers at Quizlet did a nice comparison of Cloud Spanner's performance and scaling characteristics compared with MySQL:

A detailed paper about Spanner appeared in OSDI 2012:

To all the people continuing to improve Spanner today, congrats on the launch! Great work!

Melinda Gates:
Optimism isn’t the passive expectation that things will get better.
It’s the conviction we can make things better.

Burdick ends his book by pointing to its inconclusiveness: “I can guarantee that these pages do not answer your every last question about time.” This is how it should be and clearly what Burdick intended: You realize that there are far more open puzzles about time than what you thought before opening the book. The three minutes during which you have been reading this short review are now ending: How does your brain connect the you that started three minutes ago with the present you? How does it fold together the events of these three minutes into the unitary experience of the passage of three minutes? At the end of “Why Time Flies,” you will be puzzled by what “the present” really means; you will be asking yourself how we know, without looking at a clock, what time it is, how we know that time flies, and what it even means that time flies. You will be closer to what is today’s state of scientific knowledge about the nature of time: an enchanting enigma.
