I've read this book recently and found it a very useful overview of ML. It is a bit theoretical which is good for somebody that comfortably reads math notation. Also the notation is pretty consistent which makes connections between methods and algorithms stand out.

Amazon Snowball 11 years ago

The math for the time to transfer comparison is interesting:

"Even with high-speed Internet connections, it can take months to transfer large amounts of data. For example, 100 terabytes of data will take more than 100 days to transfer over a dedicated 100 Mbps connection. That same transfer can be accomplished in less than one day, plus shipping time, using two Snowball appliances."

With a 100 Mbps connection it takes over 100 days [1] but with a 100 times faster connection (10 Gbps) it takes less than a day :)

[1] Assuming no network overhead it is 92.6 days

I was wondering what that means too - maybe the strange unit ($103 kWh per hour) is a clue to what they are talking about. Remember this is temporary storage for wind or solar energy, presumably to be extracted when the sun goes down or the wind stops turning the blades.

In the first two images you link there are dual mode indicators - one in the middle and one just by the value itself - in what looks like a manual they are both shown lit up at the same time which seems more like a problem with the documentation than what is shown in the actual aircraft picture (your third link). I'd venture a guess that in "V/S" mode you'd see that indicated next to the number just as you see "FPA" in the cockpit image.

A little gem from the article: "It was an extremely ugly, long (2 years!) divorce hearing: it made the newspapers because of Bell’s allegations of “extreme cruelty” by Feynman, including the notion that he spent all of his waking hours either doing calculus and playing the bongos."

I wonder if using the supercharger deteriorates the battery more than a more gentle charge (I am warned about this for fast charging my Leaf). Find it interesting that they ask that question on the supercharger FAQ but don't answer it:

"How often can I Supercharge? Is it bad for my battery? Supercharging does not alter the new vehicle warranty. Customers are free to use the network as much as they like."

I got a syntax error somewhere on this line: "Not because it's wrong (although it is), but because it's right."

This is interesting however - how about substantiating it with a concrete example? "C++ does have many nuances. It is a very interesting and very subtle language, to the point even machines (namely compilers) disagree about its meaning."
